(Phys.org)—Researchers from the University of Michigan working in collaboration with associates from the US Air Force have created a new type of surface cover that repels oils, water, alkali solutions, acids and even non-Newtonian fluids. In their paper published in Journal of the American Chemical Society, the researchers describe their new material and the different ways it can repel various liquids. The material they’ve created works due to two separate aspects: its chemical structure and its physical layout. It’s based on a very small gauge steel mesh which has been coated with polymer (PDMS and POSS) beads. The unique pattern laid down limits surface area and has an overhanging structure that limits adhesion. Also, tiny air pockets between the beads prevent materials from actually touching other parts of the surface, preventing liquids from getting a grip.The researchers explain that surface repellents work in general by limiting the wetting hysteresis – the amount of deformation that occurs when a liquid hits a surface. Ideally the contact angle at both the front and rear of a drop remain the same – the result is a lessened impact area. In practical terms this means that the more a drop remains formed like a drop when it strikes, the less likely it is to adhere to a surface. Play Credit: J. Am. Chem.

Am. Chem. Soc., Article ASAP, DOI: 10.1021/ja310517s The researchers demonstrated the material’s ability to repel liquids by shooting various liquids through a small jet at a covered surface and filming it as it bounced off instead of adhered. They also demonstrated that the covering also provides protection from chemical attack by dunking a coated aluminum plate into several acidic solutions. Its strength in doing so, the team explains, comes about from the same properties that prevent adhesion. If an acid cannot touch a surface (because of the air pockets) it cannot destroy it.

Soc., Article ASAP, DOI: 10.1021/ja310517s Researchers have found it particularly difficult to develop surface covers that repel liquids that contain polymers, particularly non-Newtonian fluids. This is because such substances tend to deform almost immediately on contact. Thus, the challenge has been to discover a way to cause such fluids to retain their shape as they drop onto a surface. With the new material, the overhanging, eave-like edges of the beads prevent the liquid drop from distending while also preventing it from reaching an adjacent part of the surface. That limits the amount of distension and thus the deformation of the drop. More information: Superomniphobic Surfaces for Effective Chemical Shielding, J. Am. Chem. Soc., Article ASAP, DOI: 10.1021/ja310517sAbstractSuperomniphobic surfaces display contact angles >150° and low contact angle hysteresis with essentially all contacting liquids. In this work, we report surfaces that display superomniphobicity with a range of different non-Newtonian liquids, in addition to superomniphobicity with a wide range of Newtonian liquids. Our surfaces possess hierarchical scales of re-entrant texture that significantly reduce the solid–liquid contact area. Virtually all liquids including concentrated organic and inorganic acids, bases, and solvents, as well as viscoelastic polymer solutions, can easily roll off and bounce on our surfaces. Consequently, they serve as effective chemical shields against virtually all liquids—organic or inorganic, polar or nonpolar, Newtonian or non-Newtonian.

, Astrophysical Journal , arXiv A trio of researchers with The University of Hong Kong, Academia Sinica Institute of Astronomy and Astrophysics in Taiwan and Northwestern University in the U.S., has come up with an alternative theory to explain how some stellar-mass black holes can grow bigger than others. In their paper published in The Astrophysical Journal Letters, Shu-Xu Yi, K.S. Cheng and Ronald Taam describe their theory and how it might work. Citation: Another way for stellar-mass black holes to grow larger (2018, August 17) retrieved 18 August 2019 from https://phys.org/news/2018-08-stellar-mass-black-holes-larger.html Since the initial detection of gravitational waves three years ago, five more detections have been observed—and five of the total have been traced back to emissions created by two stellar-mass black holes merging. The sixth was attributed to neutron stars merging. As part of their studies of such detections, space researchers have been surprised by the size of the stellar-mass black holes producing the gravity waves—they were bigger than other stellar-mass black holes. Their larger size has thus far been explained by the theory that they grew larger because they began their lives as stars that contained very small amounts of metal—stars with traces of metals would retain most of their mass because they produce weaker solar winds. In this new effort, the researchers suggest another possible way for stellar-mass black holes to grow larger than normal.The new theory starts out by noting that some supermassive black holes at the hearts of galaxies are surrounded by a disk of gas and dust. In such galaxies, there are often stars lying just outside the disk—stars that could evolve to become stellar-mass black holes. The researchers suggest that it is possible that sometimes, pairs of these stars wind up in the disk as they evolve into black holes. Such stellar-mass black holes would pull in material from the disk, causing them to grow larger. The researchers note that if such a scenario were to play out, it is also possible that the two merging stars could wind up with a synchronized spin resulting in a stellar-mass black hole that produces more gravity waves than if the spins had not been synchronized, making them easier for researchers to spot.

DOI: 10.3847/2041-8213/aac649 , On Arxiv: https://arxiv.org/abs/1805.07026AbstractAmong the four black hole (BH) binary merger events detected by the Laser Interferometer Gravitational-Wave Observatory (LIGO), six progenitor BHs have masses greater than 20 M ⊙. The existence of such massive BHs suggests that extreme metal-poor stars are the progenitors. An alternative possibility, that a pair of stellar mass BHs each with mass ~7 M ⊙ increases to >20 M ⊙ via accretion from a disk surrounding a supermassive BH (SMBH) in an active galactic nucleus (AGN), is considered. The growth of mass of the binary and the transfer of orbital angular momentum to the disk accelerates the merger. Based on the recent numerical work of Tang et al., it is found that, in the disk of a low-mass AGN with mass ~106 M ⊙ and Eddington ratio >0.01, the mass of an individual BH in the binary can grow to >20 M ⊙ before coalescence, provided that accretion takes place at a rate more than 10 times the Eddington value. This mechanism predicts a new class of gravitational wave (GW) sources involving the merger of two extreme Kerr black holes associated with AGNs and a possible electromagnetic wave counterpart.

Beatle star Paul McCartney almost guest starred on Friends as he was offered the role of Ross’ father-in-law.Emmy-nominated casting director Leslie Litt, who was working on the NBC hit series during most of its run, revealed that McCartney, now 72, could’ve appeared in the season 4 finale of the show as David Schwimmer’s on-screen father-in-law, but he turned it down, reported Huffington Post.“I went through his manager and gave him all the details. One day, someone in the office brought me a faxed letter written to me by Paul himself! He thanked me for my interest and said how flattered he was, but it was a very busy time for him,” Litt said.If the British musician had agreed to do it, he would’ve appeared in the two-part season four finale which aired in 1998.In the said outing, Ross married Emily (Helen Baxendale) in London though he accidentally said Rachel’s (Jennifer Aniston) name instead of his bride’s name at the altar.
Kolkata: The Regional Meteorological Centre in Alipore on Wednesday issued a warning of heavy to very heavy rainfall in several South Bengal districts, including the city, in the next 24 hours. The northern parts of the state will also witness rainfall till Friday.A cyclonic circulation over the northern part of Bay of Bengal has formed into a low pressure area over the bay and its adjoining areas, bringing heavy downpour in the state. Under its influence, heavy to very heavy rain is likely to occur in North 24-Parganas, South 24-Parganas, Nadia and Murshidabad, Hooghly, West Midnapore and South 24-Parganas. Also Read – Rain batters Kolkata, cripples normal lifeAccording to the weather office prediction, the other districts will also receive moderate to heavy rainfall in the next 24 hours. It has been learnt that the low pressure trough has become stationary at one point and is moving very slowly. So, it may cause heavy rain in various places in both North and South Bengal districts. There is a possibility of strong wind blowing in some parts along with rain, the Met office has predicted.According to experts, the low pressure area over Bay of Bengal may turn into a depression during the next 24 hours, resulting in more rain in the state. In view of the prediction of heavy rainfall, the fishermen in the coastal districts have been advised not to venture into the sea as it might turn turbulent. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedAccording to a senior weather official, a few days ago a low pressure trough had formed over North Odisha and adjoining parts of Bengal and gained strength, contributing to rainfall in the state. Rain is also predicted in the North East states as well.It may be mentioned that the city and other districts have been witnessing moderate to heavy rainfall for the past few days. Continuous rain for the last few days have, however, given some relief to the city dwellers as both the temperature and the humidity levels have been brought down by the downpour.The people were experiencing sweltering heat before it started raining. The situation is likely to continue in the next couple of days, when city residents will experience comparatively comfortable weather.
Airbnb—the room rental company that does not own any rooms—has just sued the city of New York. Why? This is because the city has introduced a bill to penalise anyone who rents out their apartment for less than 30 days. This would effectively kill Airbnb’s business, which makes every household owner a potential hotelier. Airbnb provides an online listing system—anyone who owns a house, or many properties can rent out space. The business cuts into the profits of conventional hotels who have to buy land, build rooms and take care of the establishment. In Airbnb’s case, the costs are low and distributed. More importantly, thousands, even millions, of rooms suddenly become available, which eat into the market of house rentals or hotels. Airbnb is, not surprisingly, hitting old business, which also is hitting back. Also Read – Add new books to your shelfIt is also difficult to regulate. Just think. How do city governments control millions of property owners who have become instant hoteliers? Airbnb argues that its reputational system, where owners and guests rate each other, regulates the informal market. Governments disagree. Airbnb is fighting similar battles in Amsterdam, Barcelona, Berlin and even in its hometown of San Francisco, and the list is growing. Uber—the taxi service that does not own any cars—has similar battles on hand. Uber, and others like it, have turned every car owner into a potential service provider. All that Uber does is to aggregate these millions of car owners who have overnight become taxi drivers. This is why it can reduce costs and work the market—drastically undercut the market price and drive regular taxi service into the red. All this without owning a single car. Also Read – Over 2 hours screen time daily will make your kids impulsiveUber and its variants are facing tremendous hostility from the old business. I saw this at close hand when the Supreme Court of India directed that all taxis, including those run by aggregators like Uber or Ola, should convert to CNG. This was done to reduce Delhi’s runaway air pollution. But the result of this seemingly simple order was out and out war. All taxi owners—from the black and yellow, radio taxi, to the tourist taxi and all India tourist taxi—converged at the Environment Pollution (Prevention and Control) Authority (I am a member of it), which is required to oversee the implementation of the Supreme Court’s direction. They had only one demand: stop Uber and Ola. Our objective was different—to regulate the fuel used by taxis and not to stop their operations. But regulation is a challenge. In the very first meeting, the police informed us that they are helpless. They could not identify the taxi—every car had become a taxi. Uber and Ola told us that they were not taxi operators—only aggregators. In fact, their companies are registered as information technology providers. They were also not responsible for anything—customers hired cars using their platform and rated the service provided by drivers. The Delhi government had issued guidelines, which would curtail the operations of such aggregators, but Uber challenged this in the court. Finally, after weeks of protracted discussions, and often violent disagreements, it was agreed that all taxis, including those listed with the aggregators, would run on CNG. But all other issues, including the contentious issue of surge pricing, remained unresolved. Governments in India and abroad are battling with taxi operators and technology companies to formulate these rules. But why am I writing this now? The fact is Airbnb and Uber are part of the inevitable change in our future. The reason is that the modern world has formalised its economy to the point that it has become unviable. The brick-and-mortar world requires massive infrastructure, and this then requires regulations to ensure that all this operates within rules. The cost of regulations is also high and adds to the cost of running the economy. In my view, Uber and Airbnb are undercutting this world—by making the best use of the individual’s assets. In both cases, they are optimising existing resources—the cars and houses people own—to make more money and share the profits. But most importantly, these businesses are working the informal space. They are doing this to reduce costs and to expand opportunity. This is where we need to think further of what our world is about. In countries like India, informal business is the existing order of the day. Everything—from collecting sewage from homes, recycling garbage to providing transport in our cities—is managed by millions of myriad informal businesses. But we do not consider it part of our future. Worse, it defies regulation as we know it today. So, it must go. But given that the formal economy comes with costs, we cannot replace this informal and thriving business. But to kill it we neglect it; make it illegal, and altogether despise it. But still, it stays. We just can’t make it work. So, is it time we thought of a different business future? Let’s discuss this again.(The writer is Editor of Down To Earth magazine.

Kolkata: Taking strong exception to road blockades staged by college students over attendance mandate, West Bengal Education Minister Partha Chatterjee has asserted the government will be forced to take action if the agitators cause inconvenience to public for “personal benefit”. A large number of students from two institutes – Shibnath Shastri College and Heramba Chandra College – took to streets on Thursday and Friday to protest against the Calcutta University (CU) mandate of 60 per cent minimum attendance for appearing in examinations. Also Read – Rain batters Kolkata, cripples normal life The agitators of Heramba Chandra College blocked thoroughfares in Golpark area for two consecutive days, demanding immediate relaxation of norms. The protest was also backed by students of Gurudas College and Jaipuria College, who demonstrated outside their campuses. The education minister said the government will not succumb to the pressure tactics of the students. “Under no circumstances will the administration tolerate such pressure tactics. Many people were inconvenienced as they (students) blocked the roads to get their demands fulfilled. This is unacceptable,” Chatterjee told reporters on Saturday. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killed Earlier this year, the CU authorities had asked all affiliated colleges to ensure that only those with a minimum 60 per cent attendance would be allowed to sit for semester exams. A list of non-eligible students was recently published at Heramba Chandra College, triggering the agitation. Chatterjee pointed out that the state education department has fixed 60 per cent attendance as a criterion to sit for semester exams, even as the UGC suggested 75 per cent attendance for higher educational institutions. “Maybe the agitating students wanted to sit for exams without attending classes or studying,” he said. Heramba Chandra College Principal Nabanita Chakraborty, who met Chatterjee Saturday morning, said the authorities are planning to reduce the cut-off figure for attendance from 60 per cent to 55 per cent. Trinamool Congress Chhatra Parishad (TMCP), the students’ wing of the ruling party, also appealed to the education minister to find a “way out of the deadlock” to restore normalcy in the institutes. TMCP president Trinankur Bhattacharya, who met the minister at his residence, told reporters that the unit has sought a solution that would be acceptable to all sides. A TMCP source said the union urged Chatterjee to consider relaxation in attendance norm for this year.

Kolkata: The state Power department has developed a comprehensive ‘Energy Action Plan’ in order to generate world-class electricity in Bengal.The Power department has been exploiting all its resources to ensure that the people here in the state can avail the quality of electricity that is normally found in Western countries. In its attempt to produce best quality power, the state government has focused on the renewable energy sector. A senior official of the department said through the development of an ‘Energy Action Plan’, the department aims to produce the best quality electricity, at par with the Western countries, in the next 2-3 years. Also Read – Rain batters Kolkata, cripples normal life”We are venturing into the unknown areas of renewable energy sources and in the future years, there will be a paradigm shift from conventional energy to renewable energy. We are taking all necessary steps to make the whole process more sustainable. How the grid integration will be done remains a big challenge for us,” a senior official of the Power department said. In the last one year, more than 10 power sub-stations have been constructed across the state to maintain better quality of electricity and also to address the voltage problem that has often been reported from some pockets, the official added. In the solar energy sector, Bengal has already achieved a significant growth through various projects. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedStressing on the generation of hydroelectricity, the Bengal government has taken up a number of new initiatives. Several hydroelectric projects are coming up on Teesta river, namely Teesta I, Teesta II, Teesta V, Teesta Intermediate state and Rammam Stage I in Darjeeling, each having a capacity of 80-84 MW. “The number of hydroelectricity resources is not plenty in Bengal. Despite the challenges, we are trying our best to generate hydroelectricity, which is one of our main focus areas in the state now,” the official said. It may be mentioned here that the Centre, during the Paris Convention in 2015, had vowed to catch up with other developed nations in the field of energy generation and power. The Centre has also made some commitments before the United Nations, saying that it will achieve the target of producing 40 percent of its power through renewable sources by the end of 2030. The overall carbon emission level in the country will also be reduced within the same period. India has so far been successful in generating 20 percent of its total power through renewable sources. The country will achieve the goal if all the states give more emphasis on renewable energy, thereby contributing towards the cause. Bengal is one of the states that has done a great deal of work on building infrastructure in the renewable energy sector. Since the Mamata Banerjee government came to power in the state, there has been a significant infrastructural reform in the energy sector. Power generation from solar energy has been given paramount importance through the launch of the ‘Aloshree’ project, a brainchild of the Chief Minister. To this end, solar panels have been set up on the rooftops of various government buildings, schools, colleges and other offices by the Power department.
Kolkata: The Meteorological Centre at Alipore has predicted that North Bengal districts may witness slight rainfall in the next few days, while the South Bengal districts are likely to stay dry.The temperature in the city may go down by a few notches. The lowest temperature in the city on Monday remained at 18.3 degree Celsius, which is 4 degrees above normal. The mercury may slide down for the next couple of days and then again start to climb up. A sudden drop in the temperature will have no major impact on the overall cold condition in the South Bengal districts, a weather official said on Monday. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedAccording to the weather office, a low pressure trough has formed over some parts of Uttar Pradesh and Chhattisgarh, as a result of which the flow of northwesterly wind has been interrupted. It may also bring some rainfall in the North Bengal districts. In South Bengal districts, the sky may remain partly cloudy during daytime. The people may witness misty morning in the next few days, which will disappear as the day progresses. After the low pressure trough becomes weak and its impact ceases, the mercury will again continue to soar up, paving the way for the advent of spring. Also Read – Bose & Gandhi: More similar than apart, says Sugata BoseThe Met office also predicted that temperature in all the South Bengal districts will be rising from early February and with this, the winter season will be bidding farewell. The prediction also says that the days will generally remain warm while the nights may be comparatively cold. It has been learnt that the people in North Bengal districts may continue to feel a cold condition for a few more days, as the temperature in some places may hover around 10-12 degree Celsius.

Fifteen artists from different backgrounds have gathered to showcase sculptures and installations on the theme of ‘Public art and its relevance’, at India International Centre. Titled ‘Sculpt for Delhi-II’, the group exhibition was inaugurated by Anil Baijal, Lt Governor, Delhi and Ambassador of Bulgaria Eleonora Dimitrova in the presence of Vijay Kumar Dev, Chief Secretary, Delhi.”Exhibitions like these offer a platform to express our thoughts through the medium of art, showcase our creativity, and bring it into the notice of concerned authorities. The authorities need to understand our strengths, and therefore use our potential in the best way possible. It is a way to communicate with them and discuss the importance of such installations and sculptures for artists as well as the public,” said Shovin Bhattacharjee, whose sculpture ‘Mystery of life’ highlights how urbanisation is destroying the nature. Also Read – Add new books to your shelf”I have tried to bring a mirror in front of the people to see the sad reality, and understand why it’s important to be sensitive towards nature,” he added. The show is conceptualised by artist and sculptor Neeraj Gupta, President, Delhi Art Society in collaboration with Indian International Centre, and will go on until March 19. Well-known artists including Bipasa Sen Gupta, Anjali Khosa Kaul, Asurvedh, Suresh Kumar, O P Khare, Sangeeta Gupta, Farhat Jamshed, Neeraj Gupta, Shreedhar Mukul Panwar, Kavita Nayyar, among others, have created tangible forms and figures of smooth stimulations, gradual escalation of symmetry and a hint of mystery for the ongoing exhibition. Also Read – Over 2 hours screen time daily will make your kids impulsiveOn this occasion, Lieutenant Governor of Delhi, Anil Baijal said that this exhibition will be a witness to the symbol of art and cultural influences, which the artists have raised with finesse. All artists have given their best to make this exhibition one of its kind. I have always been a fan of sculpture exhibitions, and I congratulate the Delhi Art Society and India International Centre for organising such an event with great enthusiasm.” Neeraj Gupta said, “This liberating form of art is a mystical practice, and thus brings together a dreamy amalgamation of form, features, ideations, and ideals. Art is what metamorphoses the world into a more humane world. ‘Sculpt for Delhi II’ is one such attempt to control your world to consecutively take over culture. Works of art displayed in public places are the magnets that may hold the public space together. They represent the relentless spiral of the energies of the people.”

Odell Beckham, Jr. is an All-Pro diva The entire Giants fanbase suffered a simultaneous heart attack last night when Odell Beckham took a shot to the leg and had to leave the preseason game against the Browns. At first, the injury appeared severe, and Beckham made it look worse when he melodramatically collapsed on his way to the locker room to get evaluated.It turns out Beckham only had a sprained ankle and ended up walking out for the second half like nothing happened, despite vying for the Oscar with his dramatic tunnel performance. Add this to knocking over kicking nets, proposing to kicking nets, boat trips, and the verdict is in: he’s the NFL’s leading diva.Beckham is a freakish talent, but his constant dramatics are exactly why Colin would never build his team around OBJ, and would gladly trade him for a bedrock left tackle.Colin sees Beckham as the guy that goes to a party with a boa constrictor wrapped around his neck because he’s addicted to attention. You don’t build championship NFL franchises by building around ‘Look at me guy.’
February 29, 2016 Waiting patiently for the day when you won’t have to keep track of all your passwords? Microsoft took a field trip this weekend to help further the development of an alternative.On Saturday, the tech giant set up shop at popular Seattle tourist site the Ballard Locks to get help from a handful of volunteers who lent their visages to the company’s research for Windows Hello, a year-old biometric authentication system for Windows 10.Related: 3 Biometrics Startups Heating Up the Password Security Race The tech giant created 3-D infrared scan of participants’ faces in an effort to “gather a wide variety of real-world scans to improve the accuracy of the facial recognition technology,” according to GeekWire.The people who donated five minutes and their likenesses signed a release ahead of time explaining that the 3-D scans would only be used for the company’s research.

Yet, people find ways to insulate themselves on social media sites and elsewhere on the web.People might unintentionally find themselves in a “filter bubble” — that is, only reading and / or engaging with content that confirms their views and opinions. Consider, for instance, what sites you head to for news (besides Entrepreneur, of course), if you use anti-tracking software and the types of posts and comments you put online. All of these aspects of your digital life might be signs of being in a filter bubble.The digital echo chamber can lead people to stop expanding their horizons and learning new information. Therefore, Hyper Island, a company that focuses on educational programs and courses as well as innovation consulting for companies, put together an infographic to help raise awareness of these filter bubbles.

6 min read Opinions expressed by Entrepreneur contributors are their own. On Oct. 21, 2016, the largest distributed denial of service attack (DDoS) in history was launched at around 7 a.m. EDT. It nailed servers belonging to a company called Dyn, an internet performance-management company that directs traffic for major sites.The Dyn attack caused a severe disruption of internet traffic to major sites, including many you may be familiar with, like Amazon, Reddit, Twitter, Tumblr, Verizon, Pinterest, Etsy, Spotify, PayPal, Comcast and even Playstation. The first attack was followed by at least two more.Back in 2012, there was a DDoS attack that took out the websites of JPMorgan Chase, Bank of America, Wells Fargo, Citigroup and other financial companies. In 2007, a DDoS attack literally knocked most of Estonia off the grid.How do these attacks work? The hackers look for a distribution model that can deliver sufficient traffic — in this latest case, a webcam that had sold well and had easily exploitable security. Then they focus on a target. The target here seems to have been companies that act as the internet’s phone book, making sure that traffic requests find the fastest route to any particular destination.If you’re a fan of The Walking Dead, imagine a huge herd of zombies lumbering toward a valley with three fenced communities. While all three are in harm’s way, the one with the weakest fence will be overrun. The other two are more likely to withstand the onslaught.Another way to imagine this scenario is a subway car or bus contaminated with a cold virus. While everyone on board is exposed, not everyone will get sick. The virus goes where it encounters the least amount of resistance, which in this most recent attack happened to be Dyn.We can make this a problem of the past.While our government has disappointed time and again, in particular on matters of cybersecurity, a DDoS solution may possibly be only a rule or two away from becoming reality. That is, of course, if the new administration truly focuses on the issue.In that case Congress will actually agree on the day of the week to discuss the issue, and we can all say adios to the debate about whether the “Great Wall of Mexico” will be the answer to most of our problems.Related: Expert Hacker Shares 3 Ways Small Businesses Can Minimize Cybersecurity Threats The solution may lie in the way many ATMs now handle the new chip technology in credit and debit cards. When you make a request for cash or any other transaction, many machines will not release your card until you grab your cash or completely finish your transaction. This ensures that consumers don’t leave their cards in machines, which of course can create a very real vulnerability.When it comes to the Internet of Things (IoT) devices, the six billion (and geometrically increasing) connected and interconnected devices that surround us in our personal and business lives, the same principle might help. However, it would have to become the law of the land to work — a law that would include authority over trade, i.e., products coming in from overseas.Meanwhile, the “insert and release only when the transaction is completed” ATM process is a security measure designed to better protect your card, your accounts and your financial institution. If all IoT devices required the user to set a long and strong password before the device would function, a major vulnerability available for use by hackers in DDoS attacks would go the way of three-card monte scams.In the meantime, there are a few things you can do to put your organization in the best position to survive a DDoS attack. While these measures are somewhat technical, they are within the skill sets of whomever is in charge of your digital security.1. Identify a DDoS attack early.You can do this with the right Intrusion Detection System (IDS) or a state-of-the art firewall that uses “Stateful Inspection.” These are techniques that can alert you to an attack and allow you to respond before systems fail. Another good move: having a technology professional that is capable of identifying traffic that looks like a DDoS attack and is ready to respond by immediately applying filters to the inbound DDoS traffic.Related: 7 Cybersecurity Layers Every Entrepreneur Needs to Understand 2. Have plenty of bandwidth available.Bandwidth is pretty cheap, and if you are able to over-provision what you need, you can ride out smaller attacks or at least buy some time to react properly to larger attacks.3. Have a rule book.Apply the right technical defenses at your perimeter. For example, you could “rate-limit” your web server so that only so many traffic requests are allowed. This will keep your server from getting swamped. Doubtless, it will still slow down during a DDoS attack, but it won’t fail.There are other things you can do that are beyond a generalist’s knowledge, but are straightforward for a professional who handles the engine room of your online presence. One strategy is to add network rules that dump requests from suspicious places or deny all traffic that doesn’t come from trusted sources.Your IT team may decide it makes sense to time-out suspicious connections, drop malformed packages or set lower flooding thresholds on certain types of traffic. It is crucial to have these rules — however you choose to throttle them — applied to all routers and firewalls and even internal internet-working components to filter out the most common kinds of DDoS-type traffic.4. Get your provider involved.Your service provider will have better tools than anyone else when it comes to locking down the DDoS traffic headed your way. Alert the provider as soon as you see something. The company can even “null route” your address (a network route that goes nowhere) so you will see no DDoS traffic at all while it figures out how to neutralize the attack.5. Outsource your traffic.There are technical firms that specialize in filtering traffic for you in an emergency. When a DDoS attack occurs, all your traffic moves through one of their routers first, and they are very good at blocking all the DDoS traffic that would be coming your way.Related Offer: Experience ESET’s award-winning antivirus software right now with a 30-day free trial.While you cannot prevent someone from launching a DDoS attack against your company, you can be prepared to mitigate its impact. The key thing is to assume that it’s going to happen and be as ready for it as possible.

A recent report from CB Insights found that healthcare Artificial Intelligence startups have raised $4.3 billion across 576 funding rounds in the last five years – more than any other sector. Investment flowing into building AI that works with people to tackle healthcare issues will continue globally. Meanwhile, finding sustainable answers to tragic conditions like Alzheimer’s Disease will require accurately kept health records to advance progress — and take the willing participation of people whose lives are fatally impacted by the disease. The party ultimately responsible for finding the answer to Alzheimer’s might not be human — or at least, the effort to rid the world of the disease may not be fully a human one.Artificial Intelligence presents the medical field with new opportunities to use learnings from existing and newly created data sets to solve complex human issues over the next few years. The technology’s complementary utility for health science and medical research offers new opportunities to unearth minuscule clues from individual patient histories that lead to global breakthroughs. AI has the potential to serve as a natural partner for medical researchers and professionals who spend careers combing through records to uncover trends and anomalies.Related: AI Is Transforming Healthcare as We Know It. Here’s a Look at the Future — and the Opportunities for Entrepreneurs.AI helps people find medical answers.As an industry, health science is beginning to realize the full benefits of using precision medicine to treat disease. Early success stories include making progress in cancer detection and uncovering potential health indicators from medical histories and DNA analysis. The underlying idea of using AI for health science, in particular, is to look at people’s specific genetic or molecular profiles and determine what personalized treatment works best on a case-by-case basis.In the coming years, successfully advancing precision health science will depend on collecting and storing data representing diverse patient populations. It will also rely on the health science sector’s ability to develop sophisticated AI and machine learning algorithms that mine massive amounts of data to answer very specific healthcare questions. Questions like: how do we find the indicators hidden in countless health records? Which genetic variants matter? Why does one disease impact a patient and not someone with a similar genetic makeup? AI can serve as as a means to helping the health science sector answer some of these questions, analyze specific factors with precision and bring clarity to patients earlier in the diagnosis discovery process.Related: Wonders Artificial Intelligence is Doing For The Healthcare SectorAI’s real world impact across health sectors.AI’s real world impact on health science has already materialized in the form of new pharmaceutical combinations, more promising hypotheses, improved medical diagnostics, targeted risk factor analysis and reporting that leads to more accuracy in personalized medicine. AI can fully absorb, contextualize and analyze critical healthcare information in the time it takes a human counterpart to read through a few records. The technology is built to mobilize and manage large data sets autonomously. Meanwhile, human counterparts can focus on communicating the benefits of AI findings, proactively using them to address individual medical concerns and offer more personalized patient care.AI can integrate data from multiple sources and determine relevance to specific cases swifter than humans. The technology can analyze data in real-time and produce actionable insights that would take several hours — or years in some cases — for people to complete. When built responsibly using objective data sets and lab-tested technology, AI does not have preconceived notions about the medical records, DNA and RNA analysis and general information it sorts through, eliminating potential biases and erroneous conclusions.AI’s health science success hinges on the availability of human-curated training data sets that allow for performance and bias testing prior to AI entering the market. The opportunity to connect AI and countless data sets presents the greatest opportunity for medical professionals looking toward technology for answers. In practice, AI’s core ability to automate data analysis frees up medical research people to focus on the end result, apply findings to real world medical or pharmaceutical trials, and, ultimately, adapt individual healthcare plans to incorporate new methods.Related: How AI is Making the Impossible Possible in Healthcare SectorLooking ahead to an uncertain future.The biggest challenge for health practitioners turning to AI in 2019 will remain the availability of curated data sets needed to train algorithm-driven technologies destined for disease detection and other crucial medical work. AI must be trustworthy enough to make accurate predictive assessments that dramatically impact patient care and health results in the real world. The process of preparing AI for health will become easier in the near future as the technology advances, regular people become more familiar with AI and its real world applications for disease prevention prove successful.After all, disease prevention is the holy grail. Technologies, like AI, that enable early disease detection and interception will transform patient care wholesale. AI can help medical professionals detect diseases earlier and give people impacted by those diseases a fighting opportunity to overcome them.Undoubtedly, human efforts to rid the world of Alzheimer’s disease, and other deadly illnesses or inherited conditions, will advance with the support of data-driven technologies. Tapping AI for those tasks will allow doctors and medical professionals to focus on providing more precise and empathetic patient care. Researchers can spend time making sense of AI-driven findings in order to bring machine-discovered remedies into a very human reality, like living with Alzheimer’s, that changes lives — and saves them.

For the next version of its Mac operating software, Apple is coming out of the desert and heading to the see. macOS Catalina debuts this fall, and it’s highlighted by the breakup of iTunes into three separate apps and the promise of more iOS apps making their way to the Mac.”We love the Mac, and our customers do too,” CEO Tim Cook told attendees at Apple’s Worldwide Developers Conference today (June 3). Here’s how Apple plans to show that love with macOS Catalina.Farewell, iTunesEven iTunes’ most ardent fans — and surely, there are dozens — would have to admit that Apple’s music player has gotten bloated over the years, adding all sorts of multimedia and device syncing features on top of its original mission of just managing your music.MacBook Air vs MacBook Pro: Which 13-inch MacBook Is Right For You?Apple’s entry-level MacBook Air and Pro look pretty similar, but our testing proved they differ in crucial ways.Your Recommended PlaylistVolume 0%Press shift question mark to access a list of keyboard shortcutsKeyboard Shortcutsplay/pauseincrease volumedecrease volumeseek forwardsseek backwardstoggle captionstoggle fullscreenmute/unmuteseek to %SPACE↑↓→←cfm0-9接下来播放Which Cheap Tablet Is Best?

The new Music app will focus almost entirely on music playback, with Apple’s Craig Federighi describing the new app as “blazingly fast.” Apple Music subscribers will be able to get personalized recommendations from within the app.As for syncing your device, that now takes lace in the Finder, where your iPhone or iPad will appear as just another drive you’ve plugged into your Mac. Apple envisions the process taking place in the background, but you’ll be able to drag songs, podcasts and other media over from Apple’s apps onto your mobile device.The other remnants of iTunes can be found in the new Podcasts and TV apps, which will work a lot like they do on iOS devices. Podcasts will play back your favorite audio shows, and a new machine-learning powered feature will be able to search for spoken content, so you can search for episodes using words and phrases that appear in the podcasts themselves.As for the new TV app, it will give Mac user access to the Watch Now and Apple Channels features already enjoyed by iOS users on their version of the TV app. Newer Macs will be able to enjoy 4K HDR playback with HDR10 and Dolby Vision support.Project CatalystAt last year’s WWDC, Apple announced plans to make it easier for app makers to bring their software over to the Mac, with macOS Mojave showing how it’s done with apps like Apple’s own News offering. The other show dropped at this year’s developer conference, with app makers now gaining access to what Apple calls Project Catalyst.Project Catalyst is aimed at bringing iPad apps over to the Mac, and there are more than 1 million of those, according to Federighi. The feature will be available through Apple’s Xcode developer tools.Apple says that apps like Twitter, Asphalt 9 and Jira Cloud are already taking advantage of Project Catalyst to produce Mac versions.SidecarIf you’re the kind of person who likes dual-display setups to get more work done, macOS Catalina is adding a feature that should interest you, especially if you use one of Apple’s laptops. The updated OS adds a feature called Sidecar that will let you turn your iPad into a second display.With Sidecar, you’ll even be able to use an Apple Pencil on iPad that support that input device to control and interact with apps on your Mac via that secondary screen.AccessibilitymacOS Catalina boosts the accessibility features on the Mac by adding voice control, with similar support coming to iOS devices this fall. In a demo video, Apple executives showed off how voice controls can halde everything from dictation to navigation. The feature will even add numbers to files and photos so that you can select them with your voice.Improved securityWhile macOS Catalina splits up iTunes, it’s combining two other apps — Find My iPhone and Find My Friends. (As with the accessibility improvements, this enhancement is headed to iOS devices as well, with iOS 13.) The new Find My feature will be your one-stop location tracking app for keeping tabs on your friends and assorted Apple devices.One new twist involves the ability to find devices even if they’re offline — particularly important if you’ve lost your MacBook Pro, and it’s asleep. Apple devices will now use secure Bluetooth beacon technology so that they’re detected by other nearby Mac users who are online. That encrypted location data will be anonymously forwarded to you so that you can find that offline laptop. As described by Apple, the process sounds a lot like the technology that leading key trackers use to pinpoint the location of missing items by crowd-sourcing the location information.New Macs with T2 security chips add a new Activation Lock feature in macOS Catalina that require your login information to re-active a stolen or misplaced laptop. That essentially makes your computer useless to a thief, Apple says.Other system app improvementsLook for other apps to gain new features in macOS Catalina, though Apple breezed through the changes during today’s keynote. Photos gets a new browsing experience similar to the one slated for iOS 13, while the Notes app gains a new gallery view. Apple is completely redesigning Reminders for the Mac as well.Another app making the leap from iOS devices to the Mac is Screen Time, which makes its Mac debut in macOS Catalina. Expect the same features like time limits to make their way to the Mac, with those limits enforced across all your Apple devices.macOS Catalina availabilityThe final release of macOS Catalina comes this fall. Developers will be able to get their hands on a beta today, while the public will have to wait until July for their chance to test out the new macOS features.Editors’ Note: This story has been updated to correct information about how syncing will be handled post-iTunes.For all the Apple announcements from today, check out our WWDC 2019 hub page. by Taboolaby TaboolaSponsored LinksSponsored LinksPromoted LinksPromoted LinksYou May LikeKelley Blue Book5 Mid-engine Corvettes That Weren’tKelley Blue BookUndoForbes15 Cities With the Worst Drivers in AmericaForbesUndoCNN International for ANAWhy Tennis Pundits Are Tipping This WomanCNN International for ANAUndoTODAYCeline Dion Discusses Her Recent Weight Loss: ‘Everything’s Fine’TODAYUndoMy Food and FamilyHealthy, Homemade Drunken Thai Noodles In Just 20 MinutesMy Food and FamilyUndoVerizon WirelessThis new phone will blow your mind.Verizon WirelessUndoAdvertisement
