Astronomy & Space news

	Rogue supernovas likely flung into space by black hole slingshots Rogue supernovas that explode all alone in deep space present an astronomical mystery. Where did they come from? How did they get there? The likely answer: a binary black hole slingshot, according to a new study by Ryan Foley, a professor of astronomy and physics at the University of Illinois.
	Cassini to make last close flyby of Saturn moon Dione NASA's Cassini spacecraft will zip past Saturn's moon Dione on Monday, Aug. 17—the final close flyby of this icy satellite during the spacecraft's long mission.
	Rosetta's big day in the sun ESA's Rosetta today witnessed Comet 67P/Churyumov–Gerasimenko making its closest approach to the sun. The exact moment of perihelion occurred at 02:03 GMT this morning when the comet came within 186 million km of the sun.
	Parkes telescope takes on the Roger Federer of space Using the moon and the GPS system, scientists have turned CSIRO's 64-m Parkes radio telescope in eastern Australia into a new tool for finding the highest-energy particles nature can hurl at us. The work is being presented this week at the 29th General Assembly of the International Astronomical Union in Hawai'i by CSIRO Fellow Professor Ron Ekers, on behalf of a team from Australia and Europe.
	Why is it tough to land on a comet? Why is landing on a comet so difficult and what does this tell us about future missions to comets and asteroids?
	The dwarf planet Haumea The Trans-Neptunian region has become a veritable treasure trove of discoveries in recent years. Since 2003, the dwarf planets and "plutoids" of Eris, Sedna, Makemake, Quaoar, and Orcus were all observed beyond the orbit of Pluto. And in between all of these, Haumea – that odd, oblong-shaped dwarf planet that has its own system of moons – was also discovered.

Technology news

	Software can automatically critique composition of digital photographs Everyone may be a critic, but now Penn State researchers are paving a way for machines to get in on the act. However, the researchers add that their photo-analysis algorithm is designed to offer constructive feedback, not to replace photographers.
	Ohm has worked up a drop-in replacement for car battery Ohm is a 6-pound drop-in replacement for your car battery. What's not to like about what it claims to deliver. It never needs jump-starting. Works on the coldest days (in temperatures as low as -40C). Lasts more than twice than lead-acid batteries, which go for three years. Here, you are looking at a 7-year average lifetime. No lead, no acid. When Ohm says it is a drop-in replacement they mean that it is installed in the same way.
	Transforming farm residues into biofuels and more To cut the cost of biofuels, their production-process can be enhanced to include additional valuable biochemical compounds. A recent experimental study focuses on one source of biomass: residues from Brazilian palm oil production.
	Could a digital pen change how we diagnose brain function? For all of the advances in medical technology, many of the world's most widely-used diagnostic tools essentially involve just two things: pen and paper.
	Money gushes into California firm's water-saving shower A super-efficient shower fixture that reduces water waste by 70 percent is gaining enthusiastic backing from some of Silicon Valley's biggest names, reaping in some $1.38 million in just two days.
	Researchers at RIT seek to solve the problem of looping with Meshed Tree Protocol The next breakthrough in computing that will make our computer networks more reliable, faster and more secure against cyber attacks is being developed at Rochester Institute of Technology.
	On Wikipedia, politically controversial science topics vulnerable to information sabotage Wikipedia reigns. It's the world's most popular online encyclopedia, the sixth most visited website in America, and a research source most U.S. students rely on. But, according to a paper published today in the journal PLOS ONE, Wikipedia entries on politically controversial scientific topics can be unreliable due to information sabotage.
Apple more than doubles hiring of women and minorities Apple says it more than doubled the numbers of women, blacks and Hispanics hired in the last year, although that barely moved the needle in terms of improving the diversity of its total workforce.
	Google gets third extension to answer EU case Brussels has given Google an extension until the end of August to answer an anti-trust case alleging that it abuses its search engine's market dominance, a company spokesman said Thursday.
	Drawing in the third dimension Imagine you could reach inside your old Batman comic, grab the Caped Crusader by the shoulder, and spin the whole scene around to get a new 3-D view.
	Australia court sides with Internet firms in piracy row Australians who illegally downloaded the movie "Dallas Buyers Club" will not be asked to pay for the film just yet, after the Federal Court on Friday decided not to release their names and addresses.
We should not dismiss the dangers of 'killer robots' so quickly In an open letter I helped publish on July 28 – which has now been signed by more than 2,700 artificial intelligence (AI) and robotics researchers from around the world – we stated that "starting a military AI arms race is a bad idea, and should be prevented by a ban on offensive autonomous weapons beyond meaningful human control".
	Don't expect straight answers on data sharing from the firms that profit from it Data is a new currency of sorts: we all generate a lot of it, and many companies already use it to serve their ends or ours. But, for many very good reasons, it's not easy to persuade people that they should give their data away. There are more than enough surveillance scandals or data breaches to make an open approach seem like a bad idea.
	How to protect planes and passengers from explosions on the surface of the sun Air travel today is extraordinarily safe. Despite the high profile downings of MH370 and MH17, aviation magazine Flightglobal found 2014 to be the safest ever year of air travel. But natural events, such as the Icelandic volcanic eruption and ash cloud in 2011, can sometimes pose unexpected but critical questions for air safety.
	Breaking the US government's hold on the internet won't be easy The internet today is far bigger and more inextricably linked to our daily lives than its creators in the 1970s and 1980s could have imagined. So perhaps it is not surprising that some of the structures put in place decades ago may have failed to keep pace with its rapid evolution.
	Researchers carefully protect dangerous pathogens – but how secure are all their data? Ebola, smallpox, anthrax and many others: the most dangerous microorganisms are strictly regulated in the United States. The federal government oversees use of 65 so-called select agents with "the potential to pose a severe threat to public, animal or plant health, or to animal or plant products." Before scientists can work with them to learn more, find cures or create vaccines, they must meet a long list of conditions. The goal is to keep deadly infectious agents safely under lock and key, where they can't threaten the general population or fall into the wrong hands.
	Taiwan hits Uber with $1m in fines over nearly a year Taiwan has fined Uber a total of US$1 million since September for improper registration, turning up the pressure on the app-based taxi service as authorities mull revoking its license to operate on the island.
	Oceanic junk ranges from Legos to suspected jet wreckage For years along the Cornish coast of Britain, Atlantic Ocean currents have carried thousands of Lego pieces onto the beaches. In Kenya, cheap flip-flop sandals are churned relentlessly in the Indian Ocean surf, until finally being spit out onto the sand. In Bangladesh, fishermen are haunted by floating corpses that the Bay of Bengal sometimes puts in their path.
Excess baggage: Uzbek airline starts weighing passengers Plump passengers beware! The national airline of Uzbekistan says it has begun weighing those travelling along with their carry-on luggage.
	In a slow-growth world, technology stocks are trending again Technology stocks are trending big-time as investors latch on to innovative companies racing ahead in a slow-growth world.

	Studies reveal how anesthesia's brain effects differ in older adults and in children Recent Massachusetts General Hospital (MGH) investigations into the neurobiology underlying the effects of general anesthesia have begun to reveal the ways different anesthetic agents alter specific aspects of the brain's electrical signals, reflected by EEG (electroencephalogram) signatures. While those studies have provided information that may lead to improved techniques for monitoring the consciousness of patients receiving general anesthesia, until now they have been conducted in relatively young adult patients. Now a series of papers from MGH researchers is detailing the differences in the way common anesthetics affect the brains of older patients and children, findings that could lead to ways of improving monitoring technology and the safety of general anesthesia for such patients.

Study cautions against statins as general preventive medicine Statins' success in reducing atherosclerosis-related events has elevated the medications to wonder-drug status, with some researchers advocating for their wider use as a preemptive therapy for cardiovascular disease. Using statins, however, can have side effects, including memory loss, muscle problems and increased diabetes risk. A new study in the American Journal of Physiology—Cell Physiology explains why statins are more beneficial in some cases than others and highlights the importance of weighing individual risk when considering statins as a preventive measure.
	Vitamin D in teens: Don't overdo it, bad things might happen Dosing obese teens with vitamin D shows no benefits for their heart health or diabetes risk, and could have the unintended consequences of increasing cholesterol and fat-storing triglycerides. These are the latest findings in a series of Mayo Clinic studies in childhood obesity.
Scientists discover a pathway that controls cancer cell proliferation by nutrients In a new study by Sanford Burnham Prebys Medical Discovery Institute (SBP), researchers have identified a novel kinase cascade that regulates mTORC1, a protein complex implicated in the control of cancer cell growth in response to nutrients. The study, published in Cell Reports, provides further insight into the control of mTORC1 activation, and highlights several new potential drug targets to treat human pathologies linked to mTORC1 deregulation.
	Young minds think alike – and older people are more distractible 'Bang! You're Dead', a 1961 episode of Alfred Hitchcock Presents, continues to surprise – but not just with the twist in its tale. Scientists at the University of Cambridge have used the programme to show that young people respond in a similar way to events, but as we age our thought patterns diverge.

	Study finds little improvement in mortality rate for extremely preterm infants since 2000 About 500,000 babies are born premature in the United States each year, according to the U.S. National Library of Medicine. Those infants, born before 37 weeks of gestation, will likely deal with the threat of numerous complications or even death.
	A better way to personalize bladder cancer treatments Researchers at UC Davis, in collaboration with colleagues at Jackson Laboratory, have developed a new way to personalize treatments for aggressive bladder cancer. In early proof-of-concept research, the team took bladder tumors from individual patients, identified actionable mutations and grafted the tumors into mice. From there, the researchers simultaneously tested multiple therapies in the tumor models. Treatments that were effective in the models could then be given to patients. The research was published today in the journal PLoS One.

Big Food and public health research As an obesity researcher I have publicly grappled with the ethics of working with the food industry here on Obesity Panacea for several years.  Originally I had always leaned more towards the view of engaging with industry.  While I felt that people like Michele Simon and Yoni Freedhoff made good arguments against engaging with Big Food, I felt it was possible that the positive aspects of engagement (primarily in the form of money for research or other programs that might not be possible otherwise) outweighed their potential to do harm.
Rural medicare beneficiaries receive less follow-up care Medicare patients in rural areas have lower rates of follow-up care after leaving the hospital—which may place them at higher risk of emergency department (ED) visits and repeat hospitalizations, according to a study in the September issue of Medical Care.

Biology news

	New evidence suggests marmosets learn vocalizations from parents (Phys.org)—A team of researchers with Princeton University has found that marmosets appear to learn at least some of their vocalizations from their parents. In their paper published in the journal Science, the group describes a study they carried out with the little South American monkeys and what they learned from it. David Margoliash with the University of Chicago and Ofer Tchernichovski with City University of New York offer some insight into the work done by the team in a Perspectives piece in the same journal edition.

	Look at me! Forest-dwelling anoles 'glow' to attract attention See and be seen. In the elaborate game of seeking and attracting a mate, male anole lizards have a special trick—they grab attention by perching on a tree limb, bobbing their heads up and down, and extending a colorful throat fan, called a dewlap.
	Australia to tag sharks but rules out cull Australia's most populous state said Friday it will boost the monitoring and tagging of sharks off its beaches but ruled out culling great whites after a spate of attacks left one surfer dead and two seriously hurt.
	Comprehending chemotaxis: Team uncovers the intricate mechanisms that allow certain cells to move What if cancer cells couldn't move? What if patients – once they're diagnosed with cancer – could take a drug that made cancer cells immobile? The answer is simple: survival rates would skyrocket. But reality is complicated. It's hard to know with precision how metastasis happens. But that's what James Bear, PhD, professor of cell biology and physiology, is trying to do – understand cell movement so he and others can do something about it.
	Yes, you can make alcohol from Vegemite, but ... Vegemite has been in the news of late for all the wrong reasons. It all started when Minister for Indigenous Affairs Nigel Scullion said he'd heard the yeast extract was being used in dry communities to brew alcohol.
	Company eliminates pests from stored grain with ozone and reduce costs A new process replaces the chemical tablets phosphine and methyl bromide, which are toxic and carcinogenic, used in traditional spraying methods. This new process avoids the usual loss of 18 percent of product damaged by pathogenic organisms.
Unlikely element turns up in enzyme; commercial renewable fuels might ultimately result Tungsten is exceptionally rare in biological systems. Thus, it came as a huge surprise to Michael Adams, PhD., and his collaborators when they discovered it in what appeared to be a novel enzyme in the hot spring-inhabiting bacterium, Caldicellulosiruptor bescii. The researchers hypothesized that this new tungstoenzyme plays a key role in C. bescii's primary metabolism, and its ability to convert plant biomass to simple fermentable sugars. This discovery could ultimately lead to commercially viable conversion of cellulosic (woody) biomass to fuels and chemical feedstocks, which could substantially reduce greenhouse emissions. The research is published 14 August in Applied and Environmental Microbiology, a journal of the American Society for Microbiology.
	World's largest ever fishing impact study brings hope for Cardigan Bay Scallop fishermen Scientists from Bangor University, working together with the Welsh Fishermen's Association, Welsh Government and Natural Resources Wales have published their findings from the world's largest ever fishing impact study, funded in part by the European Fishery Fund.
