Equifax CEO Hired a Music Major as the Company’s Chief Security Officer

Susan Mauldin, the person in charge of the Equifax’s data security, has a bachelor’s degree and a master of fine arts degree in music composition from the University of Georgia, according to her LinkedIn profile. Mauldin’s LinkedIn profile lists no education related to technology or security. If that wasn’t enough, news outlet MarketWatch reported on Friday that Susan Mauldin’s LinkedIn page was made private and her last name was replaced with “M”, in a move that appears to keep her education background secret. Earlier this month Equifax, which is one of the three major consumer credit reporting agencies, said that hackers had gained access to company data that potentially compromised sensitive information for 143 million American consumers, including Social Security numbers and driver’s license numbers. On Friday, the UK arm of the organisation said files containing information on “fewer than 400, 000” UK consumers was accessed in the breach. Read more of this story at Slashdot.

A nanoparticle-coated skin patch could treat obesity and diabetes

A new study out today in ACS Nano presents an interesting and effective way to reduce fat stores in the body. Researchers at Columbia University and the University of North Carolina showed that a patch loaded with nanoparticles could reduce fat, increase energy expenditure and ameliorate type-2 diabetes in obese mice. The patch consists of an array of microscopic needles that help deliver drugs enclosed in nanoparticles directly into fat lying beneath the skin. Those drugs help turn white fat, which stores energy, into brown fat, which burns energy. Humans have both types, but as we age, we lose more and more of our brown fat, leaving mostly white fat behind. Therefore, it’s harder to get rid of the fat we have once we store it. Turning white fat into brown — a process called browning — has been a concept explored by researchers looking to treat obesity and diabetes , but earlier efforts have been largely done with pills or injections, which can cause a number of side effects since they deliver the drugs to the entire body. This patch, however, can concentrate the drug to just the area with the fat. And when they tested it on obese rats, putting a patch with drug on one side and a patch without drug on the other, researchers found that the drug side showed around 30 percent reductions of a particular type of white fat. Additionally, genes associated with brown fat were upregulated in the treated side, meaning the changes appeared to be due to a browning of the white fat stores. The patches even had an effect in healthy mice, leading to increased metabolic activity and upregulated brown fat genes. The research team is now working on figuring out which drugs work best and at which concentrations. The treatment isn’t ready for human testing, but these first results seem promising. “Many people will no doubt be excited to learn that we may be able to offer a noninvasive alternative to liposuction for reducing love handles, ” Li Qiang, one of the lead researchers of the study, said in a statement . “What’s much more important is that our patch may provide a safe and effective means of treating obesity and related metabolic disorders such as diabetes.” Via: Phys.org Source: ACS Nano , Columbia University

Canada’s new radio telescope starts mapping the universe

On September 7th, an extraordinarily powerful radio telescope in Canada has begun listening to the sounds of the universe. The Canadian Hydrogen Intensity Mapping Experiment or CHIME will help scientists learn more about the history of the cosmos, radio bursts from pulsars and gravitational waves, the ripples in spacetime whose existence were finally confirmed by scientists in 2016. CHIME looks like a collection of four 100-meter-long skateboarding halfpipes, but they weren’t made for anybody to skate on. They were built over the past seven years to hear very weak signals from the universe and to gather one terabyte of information per second all day, every day. That means it’s constantly creating and updating a massive 3D map of space. When the 50 Canadian scientists from the University of British Columbia, the University of Toronto, McGill University and the National Research Council of Canada (NRC) started conceptualizing the project, there was no system that could handle that amount of information. Thanks to advances in video game hardware, the system now exists. Since 1 TB per second is pretty insane, CHIME compresses the info it gathers by a factor of 100, 000 first before saving files on disks. Now that it’s up and working, CHIME is ready to work towards achieving its primary goal: measuring the acceleration of the universe’s expansion. An accurate measurement of the expansion will help scientists figure out what causes it, whether it’s actually the mysterious form of energy that’s believed to be permeating space called ” dark energy ” or something else. By extension, the telescope’s data could one day confirm if dark energy truly exists. University of British Columbia’s Dr. Mark Halpern explains: “With the CHIME telescope we will measure the expansion history of the universe and we expect to further our understanding of the mysterious dark energy that drives that expansion ever faster. This is a fundamental part of physics that we don’t understand and it’s a deep mystery. This is about better understanding how the universe began and what lies ahead.” Source: CHIME

A Canadian University Gave $11 Million To a Scammer

A Canadian university transferred more than $11 million CAD (around $9 million USD) to a scammer that university staff believed to be a vendor in a phishing attack, a university statement published on Thursday states. From a report: Staff at MacEwan University in Edmonton, Alberta became aware of the fraud on Wednesday, August 23, the statement says. According to the university, the attacker sent a series of emails that convinced staff to change payment details for a vendor, and that these changes resulted in the transfer of $11.8 million CAD into bank accounts that the school has traced to Canada and Hong Kong. The school is working with authorities in Edmonton, Montreal, London, and Hong Kong, the statement reads. According to the university, its IT systems were not compromised and no personal or financial information was stolen. A phishing scam is not technically a “hack, ” it should be noted, and only requires the attacker to convince the victim to send money. The school’s preliminary investigation found that “controls around the process of changing vendor banking information were inadequate, and that a number of opportunities to identify the fraud were missed.” Read more of this story at Slashdot.

Ancient Tablet Reveals Babylonians Discovered Trigonometry

An anonymous reader quotes a report from Science Magazine: Trigonometry, the study of the lengths and angles of triangles, sends most modern high schoolers scurrying to their cellphones to look up angles, sines, and cosines. Now, a fresh look at a 3700-year-old clay tablet suggests that Babylonian mathematicians not only developed the first trig table, beating the Greeks to the punch by more than 1000 years, but that they also figured out an entirely new way to look at the subject. However, other experts on the clay tablet, known as Plimpton 322 (P322), say the new work is speculative at best. Consisting of four columns and 15 rows of numbers inscribed in cuneiform, the famous P322 tablet was discovered in the early 1900s in what is now southern Iraq by archaeologist, antiquities dealer, and diplomat Edgar Banks, the inspiration for the fictional character Indiana Jones. Now stored at Columbia University, the tablet first garnered attention in the 1940s, when historians recognized that its cuneiform inscriptions contain a series of numbers echoing the Pythagorean theorem, which explains the relationship of the lengths of the sides of a right triangle. (The theorem: The square of the hypotenuse equals the sum of the square of the other two sides.) But why ancient scribes generated and sorted these numbers in the first place has been debated for decades. Mathematician Daniel Mansfield of the University of New South Wales (UNSW) realized that the information he needed was in missing pieces of P322 that had been reconstructed by other researchers. He and UNSW mathematician Norman Wildberger concluded that the Babylonians expressed trigonometry in terms of exact ratios of the lengths of the sides of right triangles, rather than by angles, using their base 60 form of mathematics, they report today in Historia Mathematica.

Study finds massive volcano range hidden in Antarctica’s ice

A new study claims to have found a huge expanse of volcanoes lurking beneath the ice in Antarctica . Scientists unearthed a total of 91 previously undiscovered volcanoes — some stretching up to 3, 850 metres (12, 600 feet) in height — in the region known as the West Antarctic Rift System (WARS). The area is comparable to the densely concentrated volcanic regions in east Africa and North America, according to researchers from the University of Edinburgh. Due to the ice sheets that cover its terrain, geologists have found it extremely difficult to study Antarctica for signs of volcanic systems. To overcome the obstacles posed by nature, the team of scientists remotely surveyed the underside of the ice using a digital elevation model known as Bedmap 2 DEM. They cross-referenced that info by examining aerial and satellite imagery. The results showed peaks of basalt rock poking up through the ice to form cone-shaped structures. Of those 178 edifices, 91 were outlined as previously undiscovered volcanoes. The study suggests that the density of the volcanoes in the WARS is one volcano per 4, 800 square miles, making it one of the world’s largest volcanic regions. Although, the results do not indicate whether the volcanoes are active, the data could allow future studies to determine just that. Whereas previous research has pointed to seismic activity in Antarctica, it is not thought to have impacted the present ice retreat. That wasn’t the case in Iceland, where studies found an increase in ice flow due to subglacial eruptions. Comparably, west Antarctica contains a thicker sheet of ice, but that may not be enough to prevent the affects of volcanic disturbance on future ice flow, suggest the scientists — especially during warmer periods . On the other hand, seeing as ice tends to slope downwards on a smooth surface, the cone-shaped structures could even act as deterrents against the current pace of glacial motion, claim the researchers.

Nanomaterial charges everyday batteries in seconds

If you want a battery that charges in seconds rather than hours, you go for a supercapacitor . There are some catches to that, though: either you give up the long-lasting energy of a chemical battery (like the lithium pack in your phone) or have to resort to exotic storage tech to get a long lifespan. Drexel researchers think they have a better balance. They’ve developed electrodes based on a nanomaterial, MXene, that promise extremely quick charging times for chemical batteries. The near-2D design combines an oxide-metal ‘sandwich’ with hydrogel to create a structure that’s extremely conductive, but still lets ions move freely as the battery builds up a charge. In the lab’s design, you can charge MXene electrodes within “tens of milliseconds” — you could top up a phone in seconds or an electric car in minutes . As is often the case, the big challenge is scaling this up to production-quality energy cells. It could be years before this reaches something you can buy. However, its very focus on supporting chemical batteries makes it more practical. Factories would only have to adapt to the new electrodes, rather than throwing out their existing battery know-how. If nothing else, the existence of the MXene design shows that ultra-fast charging is becoming more realistic. Via: ScienceAlert Source: Drexel University , Nature

A robot that milks scorpions could aid cancer research

A scorpion-milking robot designed to extract and store venom could put an end to the tricky manual method traditionally used by scientists. Researchers at the Ben M’sik Hassan II University in Morocco claim their robot not only speeds up the extraction process, but also makes it safer. Scorpion venom is used in a variety of medical fields, including cancer research, and the development of anti-malarial drugs. Current harvesting methods include electrical and mechanical stimulation, which can prove deadly for the scorpions and troublesome for scientists, due to electric shocks from the equipment. Not to mention the fact that the mere thought of grasping a venomous arachnid sounds pretty darn terrifying. The lightweight VES-4 device created by Mouad Mkamel and his team of researchers is a portable robot that can be used in the lab and in the field. It works by clamping the scorpion’s tail and electrically simulating the animal to express droplets of venom, which it captures and stores. The VES-4 wouldn’t be the first robot to be utlized by medical scientists. In the past, robotic devices have been used to design drugs , with researchers also recently suggesting humanoid robots be employed to grow human tissue grafts. “[VES-4] is designed to extract scorpion venom without harming the animal and to provide more safety for the experimenters, ” said Mkamel. “It could [even] be used by one person using a remote control to safely recover scorpion venom remotely.” The robot has been tested on multiple species of scorpions and can be programmed to remember them via its adjustable settings. It also contains an LED screen that displays the name of the species being milked. Source: EurekAlert!

Seattle’s $15 Minimum Wage May Be Hurting Workers, Report Finds

As companies look for ways to cut costs, Seattle’s $15 minimum wage law may be hurting hourly workers instead of helping them, according to a new report. From a USA Today article: A report (PDF) from the University of Washington (UW), found that when wages increased to $13 in 2016, some companies may have responded by cutting low-wage workers’ hours. The study, which was funded in part by the city of Seattle, found that workers clocked 9 percent fewer hours on average, and earned $125 less each month after the most recent increase. “If you’re a low-skilled worker with one of those jobs, $125 a month is a sizable amount of money, ” Mark Long, a UW public-policy professor and an author of the report told the Seattle Times. “It can be the difference between being able to pay your rent and not being able to pay your rent.” Read more of this story at Slashdot.

Researchers will attempt to ‘reanimate’ a corpse with stem cells

Brain death may no longer be a life sentence if one Philadelphia-based biomedical startup has its way. The company, Bioquark, plans to initiate a study later this year to see if a combination of stem cell and protein blend injections, electrical nerve stimulation, and laser therapy can reverse the effects of recent brain death. They’re literally trying to bring people back from the dead. “It’s our contention that there’s no single magic bullet for this, so to start with a single magic bullet makes no sense. Hence why we have to take a different approach, ” Bioquark CEO, Ira Pastor, told Stat News . As Pastor told the Washington Post last year, he doesn’t believe that brain death is necessarily a permanent condition, at least to start. It may well be curable, he argued, if the patient is administered the right combination of stimuli, ranging from stem cells to magnetic fields. The resuscitation process will not be a quick one, however. First, the newly dead person must receive an injection of stem cells derived from their own blood. Then doctors will inject a proprietary peptide blend called BQ-A into the patient’s spinal column. This serum is supposed to help regrow neurons that had been damaged upon death. Finally, the patient undergoes 15 days of electrical nerve stimulation and transcranial laser therapy to instigate new neuron formation. During the trial, researchers will rely on EEG scans to monitor the patients for brain activity. This isn’t the first time that Bioquark has attempted this study. Last April, the company launched a nearly identical study in Rudrapur, India. However, no patients enrolled and the study wound up getting shut down that November by the Indian government over clearance issues with India’s Drug Controller General. Bioquark is reportedly nearing a deal with an unnamed Latin American country to hold a new trial later this year. Whether the treatment will actually work is an entirely different matter. Bioquark admits that it has never actually tested the regimen, even in animals, and the various component treatments have never themselves been applied to brain death. They’ve shown some promise in similar cases like stroke, brain damage and comas but never actually Lazarus-ing a corpse. “I think [someone reviving] would technically be a miracle, ” Dr. Charles Cox, a pediatric surgeon at the University of Texas Health Science Center at Houston, told Stat News . “I think the pope would technically call that a miracle.” Source: Stat News
