It's no secret that more companies are getting hacked now than ever. The government is getting hacked, major corporate companies are getting hacked, and even news outlets are getting hacked. This raises the obvious question: why aren't people investing more in bolstering their security? The answer is, as a report on The Register points out, money. Despite losing a significant sum of money on a data breach, it is still in a company's best interest to not spend on upgrading their security infrastructure. From the report: A study by the RAND Corporation, published in the Journal of Cybersecurity, looked at the frequency and cost of IT security failures in US businesses and found that the cost of a break-in is much lower than thought -- typically around $200,000 per case. With top-shelf security systems costing a lot more than that, not beefing up security looks in some ways like a smart business decision. "I've spent my life in security and everyone expects firms to invest more and more," the report's author Sasha Romanosky told The Reg. "But maybe firms are making rational investments and we shouldn't begrudge firms for taking these actions. We all do the same thing, we minimize our costs." Romanosky analyzed 12,000 incident reports and found that typically they only account for 0.4 per cent of a company's annual revenues. That compares to billing fraud, which averages at 5 per cent, or retail shrinkage (ie, shoplifting and insider theft), which accounts for 1.3 per cent of revenues. As for reputational damage, Romanosky found that it was almost impossible to quantify. He spoke to many executives and none of them could give a reliable metric for how to measure the PR cost of a public failure of IT security systems.

An anonymous reader quotes a report from Phys.Org: New research by the University of Surrey published in the journal Monthly Notices of the Royal Astronomical Society has shone light on a globular cluster of stars that could host several hundred black holes, a phenomenon that until recently was thought impossible. Globular clusters are spherical collections of stars which orbit around a galactic center such as our Milky-way galaxy. Using advanced computer simulations, the team at the University of Surrey were able to see the un-see-able by mapping a globular cluster known as NGC 6101, from which the existence of black holes within the system was deduced. These black holes are a few times larger than the Sun, and form in the gravitational collapse of massive stars at the end of their lives. It was previously thought that these black holes would almost all be expelled from their parent cluster due to the effects of supernova explosion, during the death of a star. It is only as recently as 2013 that astrophysicists found individual black holes in globular clusters via rare phenomena in which a companion star donates material to the black hole. This work, which was supported by the European Research Council (ERC), has shown that in NGC 6101 there could be several hundred black holes, overturning old theories as to how black holes form.

schwit1 quotes a report from ScienceAlert: A team of astronomers has performed new calculations on the data that originally gave rise to the Planet Nine hypothesis, and these new numbers suggest that the hypothetical extra planet might not be alone -- there could be multiple planets hiding at the edge of our Solar System that we've yet to discover. If the researchers are correct -- which nobody knows for sure right now -- it could really mean a do-over for the high school textbooks. The scientists estimate that Planet Nine is 10 times more massive than Earth, and think it performs an extremely elongated orbit of the Sun, that takes between 10,000 and 20,000 years to complete. The Caltech researchers based their hypothesis for the existence of Planet Nine on the unusual movement of six large objects floating in the Kuiper belt, suggesting that their orbits are being shaped by a hidden planet.

An anonymous reader quotes a report from Washington Post: Most of the time when we talk about silly scientific papers related to alien life, we're talking about crazy ideas for how to find aliens. But a new study in the Monthly Notices of the Royal Astronomical Society proposes a way of hiding from aliens. Humans are so fickle. A lot of our search for Earth-like planets (and, by extension, for life as we know it) hinges on transiting planets. These are planets that pass in front of their host star in such a way that the transit is visible from our perspective. The movement of the planet in front of the host star makes the light from that star dim or flicker, and we can use that to determine all sorts of things about distant worlds -- including how suitable they may be for life. Professor David Kipping and graduate student Alex Teachey, both of Columbia University, determined how much laser light it would take to mask the dimming caused by our planet transiting the sun, or cloak the atmospheric signatures associated with biological activity, [such as oxygen, which is achievable with a peak laser power of just 160 kW per transit]. From the report: "According to their math, it would take 10 continuous hours of shining a 30 MW laser once a year to eliminate the transit signal in visible light. Actually replicating every wavelength of light emitted by the sun would take about 250 MW of power."

sciencehabit writes: According to a new study, 92% of Earth-like planets haven't been born yet. Science reports: "Using data from the Hubble Space Telescope, researchers estimated the rates of past star and planet formation in the universe, which is now about 13.8 billion years old. They then combined that information with data from previous surveys that estimated the amounts of hydrogen and helium left over from the big bang that still haven't collapsed to form stars. At the time our solar system formed about 4.6 billion years ago, only about 39% of the hydrogen and helium in our galaxy had collapsed into clouds that then evolved into stars, they say. That means that the remaining 61% is available to form future solar systems that may include Earth-like planets in their habitable zones, the researchers report online today in Monthly Notices of the Royal Astronomical Society. In the universe as a whole, the researchers suggest, only 8% of its original starmaking gases was locked up in stars by Earth's first birthday. The rest will, over the remaining trillions of years of the universe's lifetime, coalesce into stars whose solar systems will contain a myriad of Earth-like planets."

An anonymous reader writes: A study published in the journal Clinical Infectious Diseases details the recent trial of a drug named Truvada, which researchers think might excel at preventing HIV infections (abstract). The scientists administered the drug to 657 people at high risk for contracting HIV, including users of injected drugs. At the end of the study, every single subject was still free of the virus. This is encouraging news in the fight against AIDS, though it shouldn't be taken to mean the drug is perfectly effective. Since researchers can't ethically expose people to HIV, we don't know for sure that any of the subjects were definitely saved by the drug. Other studies have also had to be stopped because it was clear subjects who were on a placebo were suffering from noticeably higher rates of infection. Leaders in the fight against AIDS say this new study closes a "critical gap" in existing research by demonstrating that Truvada can work in real-world health programs.

New submitter shuheng writes with news that a study out of Purdue claims to have identified the sixth distinct taste known to humans: fat. The scientists say it should be called oleogustus which means "fatty taste" in Latin (abstract). Professor Richard Mattes said, Most of the fat we eat is in the form of triglycerides, which are molecules comprised of three fatty acids. Triglycerides often impart appealing textures to foods like creaminess. However, triglycerides are not a taste stimulus. Fatty acids that are cleaved off the triglyceride in the food or during chewing in the mouth stimulate the sensation of fat. The taste component of fat is often described as bitter or sour because it is unpleasant, but new evidence reveals fatty acids evoke a unique sensation satisfying another element of the criteria for what constitutes a basic taste, just like sweet, sour, salty, bitter and umami.

Beeftopia (1846720) writes In a case reported in the journal Open Forum Infectious Diseases, a woman suffering from a drug-resistant intestinal infection gained 36 pounds after receiving a fecal transplant from her overweight daughter. Previous mouse studies have shown thin mice gain weight after ingesting fecal bacteria from obese mice. The woman previously was not overweight. After the procedure, despite a medically supervised liquid protein diet and exercise regimen, the woman remained obese. Her doctor said, "She came back about a year later and complained of tremendous weight gain... She felt like a switch flipped in her body, to this day she continues to have problems... as a result I'm very careful with all our donors don't use obese people."

concertina226 writes Scientists working together from several international universities have discovered that it is possible to block a pathway in the brain of animals suffering from neuropathic pain, which could have a huge impact on improving pain relief in humans. So far, the most successful ways to treat chronic pain from a pharmacological point of view are to create drugs that that interact or interfere with various channels in the brain to decrease pain, including adrenergic, opioid and calcium receptors. However, there is another way – a chemical stimulator called adenosine that binds to brain receptors to trigger a biological response. Adenosine has shown potential for killing pain in humans, but so far, no one has managed to harness this pain pathway successfully without causing a myriad of side effects. Led by Dr Daniela Salvemini of SLU, the researchers discovered that by activating the A3 adenosine receptor in the rodents' brains and spinal cords, the receptor was able to prevent or reverse pain from nerve damage (the cause of chronic pain).

vrml (3027321) writes Biofeedback is well-known as a relaxation technique, but the HCI Lab of the University of Udine has tried to use it for the opposite purpose: making people anxious. The technique, described by a paper in the November 2014 issue of the Interacting with Computers journal, exploits heartbeat detection. While users navigated a 3D world, the computer detected and played their actual heartbeat (users were not told it was theirs) in the audio background of the virtual world. At a couple of times during the experience, the application artificially increased the frequency of the played heartbeat and then reverted it to the actual one after some seconds. The study described in the paper contrasts the technique with aversive stimuli frequently used in video games when the character gets hurt such as decreasing health bars or increasing the frequency of an heartbeat sound that is not related to the user's actual heartbeat. The biofeedback-based technique produced much larger (subjective as well as physiological) levels of user anxiety than those classic aversive stimuli.

An anonymous reader writes: Diagnosed with high blood pressure? If so, you were probably told to moderate or avoid the use salt in your food. Well, a new study (abstract found that salt is not associated with systolic blood pressure after controlling for other factors. The study found that BMI, age, and alcohol consumption all strongly influenced blood pressure, and concluded that maintaining a healthy body weight was the best way to counteract it. The publication of this research follows a CDC report from Tuesday decrying the amount of salt in children's diets — a report that lists high blood pressure as one of its main concerns. The debate on this issue is far from over, and it'll take years to sort out all the contradictory evidence.

An anonymous reader sends this report from Eurekalert: Scientists began gathering biological information only a few months after the disastrous 2011 meltdown of the Fukushima power plant in Japan. Results of these studies are now beginning to reveal serious biological effects of the Fukushima radiation on non-human organisms ranging from plants to butterflies to birds. A series of articles summarizing these studies has been published in the Journal of Heredity describing impacts ranging from population declines to genetic damage (abstract 1, abstract 2, abstract 3, abstract 4). Most importantly, these studies supply a baseline for future research on the effects of ionizing radiation exposure to the environment. Common to all of the published studies is the hypothesis that chronic (low-dose) exposure to ionizing radiation results in genetic damage and increased mutation rates in reproductive and non-reproductive cells. Meanwhile, efforts to restart Japan's nuclear power program are dead in the water.

schwit1 writes: New research by astronomers suggests that the Milky Way is about half as massive as previously estimated. It was thought to be roughly the same mass as Andromeda, weighing in at approximately 1.26 x 10^12 solar masses (PDF). This new research indicates its mass is around half the mass of Andromeda. "Galaxies in the Local Group are bound together by their collective gravity. As a result, while most galaxies, including those on the outskirts of the Local Group, are moving farther apart due to expansion, the galaxies in the Local Group are moving closer together because of gravity. For the first time, researchers were able to combine the available information about gravity and expansion to complete precise calculations of the masses of both the Milky Way and Andromeda. ... Andromeda had twice as much mass as the Milky Way, and in both galaxies 90 percent of the mass was made up of dark matter."

Rambo Tribble writes: "Writing in the American Journal of Epidemiology, researchers have found that sleeping with high ambient light levels may contribute to obesity (abstract). In a survey of 113,000 women, a high correlation was found between higher bedroom light levels and increased propensity to be overweight or obese. Excess light in the sleeping environment has long been known to adversely affect melatonin production and circadian rhythms. It is posited that such an interference with the 'body clock' may be behind these results. Although there is not yet enough evidence to call this a smoking gun, as one researcher put it, 'Overall this study points to the importance of darkness.'"

astroengine writes "The number of known planets beyond the solar system took a giant leap thanks to a new technique that verifies candidate planets found by NASA's Kepler space telescope in batches rather than one-by-one. The new method adds 715 planets to Kepler's list of confirmed planets, which previously totaled 246, scientists said Wednesday. Combined with other telescopes' finds, the overall exoplanet headcount now reaches nearly 1,700. 'By moving ... to statistical studies in a "big data" fashion, Kepler has showcased the diversity and types of planets present in our galaxy,' said astronomer Sara Seager." In other exoplanet news, a recent study found that so-called 'super earths,' planets that are bigger than Earth but smaller than gas giants like Uranus and Neptune, are unlikely to be habitable to known forms of life. The higher mass traps significantly more hydrogen during the formation of the planetary system, which results in extremely high atmospheric pressure — high enough to be hostile to known life.

sciencehabit writes "Smart, successful, and well-connected: a good description of Albert Einstein and his brain. The father of relativity theory didn't live to see modern brain imaging techniques, but after his death his brain was sliced into sections and photographed. Now, scientists have used those cross-sectional photos to reveal a larger-than-average corpus callosum — the bundle of nerve fibers connecting the brain's two hemispheres. The thickness of Einstein's corpus callosum was greater than the average, and more nerve fibers connected key regions such as the two sides of the prefrontal cortex, which are responsible for complex thought and decision-making. Combined with previous evidence that parts of the physicist's brain were unusually large and intricately folded, the researchers suggest that this feature helps account for his extraordinary gifts."

HonorPoncaCityDotCom writes "BBC reports that cases of an incurable illness called valley fever are multiplying at an alarming and mystifying rate in the American south-west. Few places have been hit as hard as Avenal, a remote city of 14,000 people, nestling in a dip in the floor of the San Joaquin Valley in what experts refer to as a 'hot zone' for coccidioidomycosis — an illness caused by the inhalation of tiny fungal spores that usually reside in the soil. 'On windy days you are more conscious of it,' says Enrique Jimenez. 'You breathe in through your nose, and try not to breathe in as much dust. I worked in the fields for a long time, my father managed a few crops out here, and we took precautions, wearing bandanas.' Valley Fever is not easy to treat. Anti-fungal drugs are available for serious cases but some patients don't respond and it can take years to clear up. It never leaves the body and symptoms can be triggered again. Some patients are on the drugs for life, at a crippling financial cost. During World War II, German prisoners held at a camp in Arizona fell ill. Germany reportedly invoked the Geneva Convention to try to get them moved. Longstanding concerns about valley fever were heightened recently when a federal health official ordered the transfer of more than 3,000 exceptionally vulnerable inmates from two San Joaquin Valley prisons where several dozen have died of the disease in recent years. Dale Pulde, a motorcycle mechanic in Los Angeles County, said he contracted the disease three years ago after traveling to Bakersfield in Kern County and was coughing so hard he was blacking out; he spit blood and couldn't catch his breath. For two months, doctors tested him for everything from tuberculosis to cancer until blood tests confirmed he had the fever. 'When I found out that health officials knew about (this disease) and how common it is, I was beside myself,' said Pulde. 'Why don't they tell people?'"

coondoggie writes "As if landing on an asteroid wouldn't be dangerous enough, a new microgravity experiment on the forces generated by an asteroid and its make-up suggests landing on one may cause a big avalanche. The rubble and dust covering asteroids and comets can feel changes in what is known as 'force-chains' between particles over much larger distances than on Earth, making these surfaces less stable than previously imagined, said Dr. Ben Rozitis of the Open University, who presented his experiment's findings (abstract) on July 4 at the National Astronomy Meeting."

New submitter mal0rd writes "NewScientist reports a 'collection of galaxies that is a whopping four billion light years long is the biggest cosmic structure ever seen. The group is roughly one-twentieth the diameter of the observable universe – big enough to challenge a principle dating back to Einstein, that, on large scales, the universe looks the same in every direction.' For reference, Andromeda is only 2.5 million light years away."

SternisheFan sends this excerpt from ABC: "On the heels of the latest NFL suicide, researchers announced today that 34 NFL players whose brains were studied suffered from CTE, a degenerative brain disease brought on by repeated hits to the head that results in confusion, depression and, eventually, dementia. The study was released just days after the murder-suicide of Kansas City Chiefs linebacker Jovan Belcher. It's not yet known what triggered Belcher's action, but they mirror other NFL players who have committed suicide. Researchers at Boston University's Center for the Study of Traumatic Encephalopathy published the largest case series study of CTE to date (abstract), according to the center. Of the 85 brains donated by the families of deceased veterans and athletes with histories of repeated head trauma, they found CTE in 68 of them. Of those, 34 were professional football players, nine others played college football and six played only high school football. Of the 35 professional football players' brains donated, only one had no evidence of the disease, according to the study." It's a good thing we protect our youth from conditions like this.

An anonymous reader writes "By taking skin cells and turning them into stem cells, a technique that is already well known, researchers at Technion Israel Institute of Technology were able to generate beating heart cells — a medical first. 'We have shown that it's possible to take skin cells from an elderly patient with advanced heart failure and end up with his own beating cells in a laboratory dish that are healthy and young — the equivalent to the stage of his heart cells when he was just born,' Lior Gepstein, study author and professor of medicine said."

An anonymous reader writes with this news out of the University of Illinois: "Scientists report that they have mapped the physical architecture of intelligence in the brain. Theirs is one of the largest and most comprehensive analyses so far of the brain structures vital to general intelligence and to specific aspects of intellectual functioning, such as verbal comprehension and working memory. Their study, published in Brain: A Journal of Neurology (abstract), is unique in that it enlisted an extraordinary pool of volunteer participants: 182 Vietnam veterans with highly localized brain damage from penetrating head injuries. ... The researchers took CT scans of the participants’ brains and administered an extensive battery of cognitive tests. They pooled the CT data to produce a collective map of the cortex, which they divided into more than 3,000 three-dimensional units called voxels. By analyzing multiple patients with damage to a particular voxel or cluster of voxels and comparing their cognitive abilities with those of patients in whom the same structures were intact, the researchers were able to identify brain regions essential to specific cognitive functions, and those structures that contribute significantly to intelligence."

ananyo writes "A landmark study involving U.S. miners that links cancer rates to diesel fume exposure has been published after a seventeen-year legal battle with an industry group. A February 27 Slashdot story had reported that lawyers for the mining industry had sent threatening letters to scientific journals advising them against publishing the study. Initiated in 1998, after the first of many legal delays, the study analyzed exposures in detail for more than 12,000 workers while controlling for smoking and other risk factors. In the end, the scientists found that miners faced a threefold risk of lethal lung cancer, and underground workers who were heavily exposed to diesel fumes faced a fivefold risk. The two concluding papers from the study are available in full."

Although reports call this latest form a 'new entity,' researchers suggest that it is instead another development in a long-standing problem.

Med-trump writes "Neanderthals, whose ancestors left Africa about 400,000 to 800,000 years ago, evolved in what is now mainly France, Spain, Germany and Russia, and are thought to have lived until about 30,000 years ago. Now scientists have identified a piece of Neanderthal DNA (called a haplotype) in the human X chromosome and conclude that this haplotype is present because of mating between our ancestors and Neanderthals. The study was published in the latest issue of the journal Molecular Biology and Evolution."

Thorfinn.au writes "A new study indicates that heavy coffee drinking staves off deadly prostate cancer in men. Some 47,911 US men were surveyed over the period 1986 to 2008 for the research. During this time some 5,035 of them developed prostate cancer with 642 dying of it. According to analysis by investigating scientists, men who drank the most coffee (a fairly normal six-plus cups per day) had a 20 per cent lower risk of developing any kind of prostate cancer. If they did get prostate cancer, the java-swillers were much less likely to die from it than others: their risk of deadly prostate cancer was no less than 60 per cent lower than normal. Even less thirsty coffee drinkers who only put away one to three cups daily saw their chance of deadly prostate cancer fall by a useful 30 per cent."
