Astronomy & Space news

	Meteorite material born in molten spray as embryo planets collided Asteroids may be a byproduct of planet formation rather than planetary building blocks, according to a recent paper in Nature.
	Hubble gazes at R Sculptoris and its hidden companion This NASA/ESA Hubble Space Telescope image shows the region around a star known as R Sculptoris, a red giant located 1,500 light-years from Earth in the constellation of Sculptor. Recent observations have shown that the material surrounding R Sculptoris actually forms a spiral structure—a phenomenon probably caused by a hidden companion star orbiting the star. Systems with multiple stars often lead to unusual or unexpected morphologies, as seen, for example, in the wide range of striking planetary nebulae that Hubble has imaged.
	New exoplanet-hunting telescopes on Paranal The Next-Generation Transit Survey (NGTS) has achieved first light at ESO's Paranal Observatory in northern Chile. This project will search for transiting exoplanets—planets that pass in front of their parent star and hence produce a slight dimming of the star's light that can be detected by sensitive instruments. The telescopes will focus on discovering Neptune-sized and smaller planets, with diameters between two and eight times that of Earth.
	Alarm sends astronauts to shelter at space station (Update) Astronauts at the International Space Station rushed to take shelter Wednesday after a system failure signaled a possible ammonia leak, but NASA said later it was likely a false alarm.
	One of the Milky Way's arms might encircle the entire galaxy Given that our Solar System sits inside the Milky Way Galaxy, getting a clear picture of what it looks like as a whole can be quite tricky. In fact, it was not until 1852 that astronomer Stephen Alexander first postulated that the galaxy was spiral in shape. And since that time, numerous discoveries have come along that have altered how we picture it.
	Asteroid to fly by Earth safely on January 26 An asteroid, designated 2004 BL86, will safely pass about three times the distance of Earth to the moon on January 26. From its reflected brightness, astronomers estimate that the asteroid is about a third of a mile (0.5 kilometers) in size. The flyby of 2004 BL86 will be the closest by any known space rock this large until asteroid 1999 AN10 flies past Earth in 2027.
	Artificial intelligence helps physicists predict dangerous solar flares Solar flares can release the energy equivalent of many atomic bombs, enough to cut out satellite communications and damage power grids on Earth, 93 million miles away. The flares arise from twisted magnetic fields that occur all over the sun's surface, and they increase in frequency every 11 years, a cycle that is now at its maximum.
	NASA launches sounding rockets into auroras to study atmospheric effects The interaction of solar winds and Earth's atmosphere produces northern lights, or auroras, that dance across the night sky and mesmerize the casual observer. However, to scientists this interaction is more than a light a display. It produces many questions of the role it plays in Earth's meteorological processes and the impact on the planet's atmosphere.
	Huygens mission: Ten years at Titan Celebrating the 10th anniversary of the pioneering Huygens mission to Saturn's moon Titan, the first successful landing on an outer Solar System world.
	What other worlds have we landed on? Think of all the different horizons humans have viewed on other worlds. The dust-filled skies of Mars. The Moon's inky darkness. Titan's orange haze. These are just a small subset of the worlds that humans or our robots landed on since the Space Age began.
	Astronauts back in US side of space station; no ammonia leak The astronauts are back in the American side of the International Space Station.
	SOFIA airborne observatory begins 2015 science campaign The Stratospheric Observatory for Infrared Astronomy, or SOFIA, Program began its third season of science flights on Jan. 13, 2015. SOFIA is NASA's next generation flying observatory and is fitted with a 2.5-meter (100-inch) diameter telescope that studies the universe at infrared wavelengths.
	Fresh supplies and experiments delivered to ISS Yesterday, ESA astronaut Samantha Cristoforetti and NASA astronaut Butch Wilmore captured the Dragon spacecraft with its supplies and new experiments for the six astronauts living 400 km above our planet.
Video: Exciting space missions ahead for 2015 After a very fruitful 2014, there is no time to rest, another busy space year is already underway.
	Experts explore the medical safety needs of civilian space travel The commercial aviation industry has medical care standards, as does NASA for traditional space missions, and the emerging commercial space transportation industry will need to define medical care practices as well. The unique risks posed by commercial spaceflight warrant the establishment of Medical Levels of Care to account for the different phases of suborbital and orbital missions, as described in an article published in New Space.

Medicine & Health news

	Possible treatments identified for highly contagious stomach virus Antibiotics aren't supposed to be effective against viruses. But new evidence in mice suggests antibiotics may help fight norovirus, a highly contagious gastrointestinal virus, report scientists at Washington University School of Medicine in St. Louis.
	Eye surgeon uses stem cells to repair damaged corneas In Hyderabad, India, Sayan Basu is using stem cells in a pilot project to restore the eyesight of patients with damaged corneas. If proven successful, the procedure could mean that Indian citizens can avoid long waiting lists for cornea transplants and avoid eye surgery altogether.
	Lack of exercise responsible for twice as many deaths as obesity A brisk 20 minute walk each day could be enough to reduce an individual's risk of early death, according to new research published today. The study of over 334,000 European men and women found that twice as many deaths may be attributable to lack of physical activity compared with the number of deaths attributable to obesity, but that just a modest increase in physical activity could have significant health benefits.
	'Titin' gene mutations will help identify patients at risk of heart failure A new study has identified genetic mutations that cause the heart condition dilated cardiomyopathy (DCM), paving the way for more accurate diagnosis.
	A paradox revealed: Cues associated with infant abuse may help reduce stress in adult brain Neurobiologists at NYU Langone Medical Center and elsewhere have found a surprising and paradoxical effect of abuse-related cues in rat pups: those cues also can lower depressive-like behavior when the rat pups are fully grown.
	One punch to knock out flu: Researcher sees universal flu vaccine ahead The fact that this year's flu shot is not a good match against this year's influenza strain is well known, and has happened before.
Research group identifies GLUT2 protein's role in zebrafish brain development Researchers from the University of Barcelona (UB) have described the key role that GLUT2 protein plays in embryonic brain development in zebrafish. A new article —highlighted on the cover of the January issue of the Journal of Cerebral Blood Flow & Metabolism— proves that this molecule depletion alters the development of brain basic structures involved in glucose sensing.
	US slipping as global leader in medical research Once the undisputed center of global innovation in medicine, the U.S. is steadily losing ground to Asia and Europe and will, if trends continue, relinquish its leadership in the coming decade. That is the conclusion of an analysis appearing today in the Journal of the American Medical Association.
	UR tests HIV vaccine pill Researchers at the University of Rochester Medical Center are testing a new oral vaccine to prevent infection with HIV, the virus that causes AIDS. The vaccine is unique because it is given as a pill, unlike most HIV vaccines tested to date that have been given as shots.
	Researchers propose new regulations for off-label uses of drugs and devices Off-label use of drugs and medical devices—using approved remedies in unapproved ways—has long been a part of medicine. The practice provides public health benefits but also presents some risks.
	Children of melanoma survivors need better protection from sun's harmful rays UCLA researchers have found that children of melanoma survivors are not comprehensively adhering to sun protection recommendations, despite them being at an increased risk for developing the disease as adults.
	Online registry will help cancer patients preserve their fertility In a world-first, the Randwick Hospitals Campus and UNSW Australia have launched an online registry that will capture a cancer patient's journey from diagnosis through to survivorship, and which can be used to help them plan for a family.
Study challenges notions of Australian men's openness to counseling Australian men have a reputation for being macho and practical, but when it comes to using phone helplines most men just want to talk about their feelings, according to researchers at the University of Adelaide.
	Revamped drug may overcome resistance in brain tumours Cancer Research UK scientists have taken steps to overcome drug resistance in glioblastoma, the most common type of brain tumour in adults, according to research published in Molecular Cancer Therapeutics.
	We need new antibiotics to beat superbugs, but why are they so hard to find? We've heard a lot lately about superbugs – bacteria that are resistant to current antibiotics. But as the threat of superbugs continues to rise, the number of new treatments available has flatlined. This has placed us dangerously close to the edge of a return to the pre-antibiotic era, when even simple infections caused death.
	Advance in the development of the first reversible male contraceptive The outer membrane of sperm cells was first described as a result of the work by a Mexican biotechnologist.
	Genetic test classifies kidney cancer Singaporean researchers have developed a genetic test that can reliably identify different subtypes of a specific kind of kidney cancer. The test has the potential to improve treatment, as it can assess a patient's prognosis and likely response to therapy.
Scientists look to heart disease and strokes for clues to treating Alzheimer's A growing body of research suggests that the most common cause of dementia in older people is a mix of vascular and Alzheimer's-related brain abnormalities, and that approximately half of people who die with Alzheimer's also have evidence of strokes in their brains. Furthermore, when strokes and hallmark Alzheimer's plaques and tangles are combined, it increases a person's likelihood of experiencing dementia. Stroke, or as it is known more generally as cerebrovascular disease, occurs with aging and is made worse by conditions like smoking, hypertension or diabetes.
Cardiac specialists recommend donor heart allocation changes A group of leading cardiac specialists has proposed new guidelines for the allocation of donor hearts to patients awaiting transplant. The changes are aimed at improving the organ distribution process to increase the survival rate of patients awaiting transplant and posttransplant.
	For obesity research, self-reported diet and physical activity data too inaccurate Asking patients to self-report their nutrition and physical activity is a common data-collection method used by obesity investigators. But a newly published expert opinion—signed by leading scientists and led by investigators at the University of Alabama at Birmingham—says this often misleading information can lead to disappointing research outcomes.
	Teens abusing prescription pills are a growing concern Parents and physicians still aren't doing enough to address the rise of "pharming," or recreational use and abuse of prescription drugs, among teenagers, according to public health researchers at Drexel University.
	Opinion: Will legal marijuana lead to more addicts? At present, cannabis is fully legalized in Colorado and Washington and will soon be fully legalized in Oregon and Alaska. Additionally, medical cannabis is legal in 23 states. The writing is on the wall that more and more states are going to legalize cannabis in various ways and that access will become easier and easier. In the face of this reality, two big questions arise: will cannabis usage skyrocket? Will addiction rates go through the roof?
	Testing for bovine tuberculosis is more effective than badger culls at controlling the disease Modelling produced by researchers at Queen Mary University of London (QMUL) has found that the only effective potential Bovine Tuberculosis (TB) control strategies are badger culling, cattle testing, controlling cattle movement, and ceasing the practice of housing farm cattle together during winter. The modelling found that in a region containing about 1.5m cows of which 3000 to 15,000 might have TB, badger culling could account for a reduction of 12 in the number of infected cattle. While reducing the testing interval by one month could reduce the number of those infected by 193.
	The math of one-night stands and long-term relationships Popular wisdom and established evolutionary science hold that the sexes seek fundamentally different relationships: men want short-term, no-strings-attached relationships whereas women value longer-term, loyal partnerships.
	You are what you 'like', according to new Facebook personality test Pretty much all of us work with computers these days. The problem with computers is that while they can complete complex calculations and recall distant details, they're terrible at sensing how you're feeling. And that can make them very frustrating.
Total milk intake dropped by nearly half when chocolate milk removed from School program Researchers from the College of Pharmacy and Nutrition, University of Saskatchewan measured milk consumption (plain milk and flavoured milk) by children in a sample of Saskatoon elementary schools. This is the first study in a Canadian elementary school population to investigate the impact of removing chocolate milk from schools.
Study links biomarkers to long-term kidney damage and death in critically ill High levels of two novel urinary biomarkers early in critical illness are associated with adverse long-term outcomes in patients with acute kidney injury (AKI), according to an international, multi-center study led by University of Pittsburgh School of Medicine Researchers. AKI is a condition that often affects those in intensive care and can occur hours to days after serious infections, surgery or taking certain medications.
	Long duration weightlessness in space induces a blood shift In a study published today in The Journal of Physiology, researchers found that in space, the shift of blood and fluid from the lower to the upper body caused by weightlessness is much higher and the blood pressure much lower than previously thought.
	Neck artery stents may not be worthwhile in 'real world' setting (HealthDay)—Placing stents in the neck arteries, to prop them open and help prevent strokes, may be too risky for older, sicker patients, a new study suggests.
The doctor is in … your mobile device It was 11:45 a.m. and Dr. Christopher Bailey's laptop was chirping, indicating a patient was on the line.
Clinical trial examines safety, effectiveness of drug to treat binge eating disorder At some doses, the medication lisdexamfetamine dimesylate, a drug approved to treat attention-deficit/hyperactivity disorder, was effective compared with placebo in decreasing binge-eating (BE) days in patients with binge-eating disorder (BED), a public health problem associated symptoms of mental illness and obesity and for which there are no approved medications, according to a study published online by JAMA Psychiatry.
Patients with advanced colon cancer having less surgery, better survival With the dawn of the modern era of new chemotherapeutic and biologic agents available for managing their disease, patients with metastatic colorectal cancer are undergoing less surgery for the removal of their primary tumors, according to research from The University of Texas MD Anderson Cancer Center.
	Depression, behavioral changes may precede memory loss in Alzheimer's Depression and behavioral changes may occur before memory declines in people who will go on to develop Alzheimer's disease, according to new research at Washington University School of Medicine in St. Louis.
	Team associates rare gene variants with side effects from chemotherapy with paclitaxel Paclitaxel is a chemotherapeutic drug that has been shown to be highly effective when treating solid tumours, such as breast, ovarian and lung tumours. However, its use frequently causes peripheral neuropathies, neurological problems that affect the vast majority of patients. Symptoms include tingling and pain in the extremities, cramping, muscular weakness and difficulty walking, in addition to others. In severe cases, the severity of these adverse effects mandates dosage reduction, and even stopping the treatment.
	Shoulder to the wheel: Parental intervention improves teen driving Motor vehicle accidents are the leading cause of teenage death in America. According to the Centers for Disease Control and Prevention, seven 16- to 19-year-olds die every day as a result of injuries incurred from road crashes. But attempts to address the problem through legislation and technological innovation have yielded limited results.
	Scientists develop novel platform for treatment of breast, pancreatic cancer Scientists from the Florida campus of The Scripps Research Institute (TSRI) have identified a novel synthetic compound that sharply inhibits the activity of a protein that plays an important role in in the progression of breast and pancreatic cancers.
	Advanced 3-D facial imaging may aid in early detection of autism Autism is a spectrum of closely related disorders diagnosed in patients who exhibit a shared core of symptoms, including delays in learning to communicate and interact socially. Early detection of autism in children is the key for treatments to be most effective and produce the best outcomes. Using advanced three-dimensional imaging and statistical analysis techniques, researchers at the University of Missouri have identified facial measurements in children with autism that may lead to a screening tool for young children and provide clues to its genetic causes.
People conform to the norm—even if the norm is a computer Often enough it is human nature to conform. This tendency makes us follow the lead of computers, even if the machines give us the wrong advice. This is the finding of a study in Psychonomic Bulletin & Review that investigates how people make judgment calls after playing role-playing video games. The research was led by Ulrich Weger of the University of Witten/Herdecke in Germany.
	Combat veterans' brains reveal hidden damage from IED blasts The brains of some Iraq and Afghanistan combat veterans who survived blasts from improvised explosive devices (IEDs) and died later of other causes show a distinctive honeycomb pattern of broken and swollen nerve fibers throughout critical brain regions, including those that control executive function. The pattern is different from brain damage caused by car crashes, drug overdoses or collision sports, and may be the never-before-reported signature of blast injuries suffered by soldiers as far back as World War I.
Taking sightlessness for a spin can harm people's attitudes toward blindness Using simulation to walk in the shoes of a person who is blind—such as wearing a blindfold while performing everyday tasks—has negative effects on people's perceptions of the visually impaired, according to a University of Colorado Boulder study.
Potassium salts aid bone health and limit osteoporosis risk, new research finds Latest research from the University of Surrey has found that the potassium salts (bicarbonate and citrate) plentiful in fruit and vegetables, play an important part in improving bone health. For the first time, the results also showed that these potassium salts reduce bone resorption, the process by which bone is broken down, therefore increasing their strength.
	Mutations linked to repair of chromosome ends may make emphysema more likely in smokers Mutations in a gene that helps repair damaged chromosome ends may make smokers—especially female smokers—more susceptible to emphysema, according to results of a new study led by Johns Hopkins Kimmel Cancer Center researchers.
New study reports worsening health conditions increase risk of mortgage default and disclosure The mortgage strain of American home ownership can lead to poor health but a new study finds that the inverse may also be true— changes in health can serve as a predictor to mortgage distress.
	US needs harm-reduction approach to drug use, researcher says The United States' law-and-order approach to reducing the supply of drugs and punishing sellers and users has impeded the development of a public health model that views drug addiction as a disease that is preventable and treatable. A new policy paper from Rice University's Baker Institute for Public Policy advocates that a harm-reduction approach would more effectively reduce the negative individual and societal consequences of drug use.
Health outcomes improve in states where nurse practitioners independently provide care As America's population ages, life spans lengthen and more individuals enroll in insurance plans under the Affordable Care Act, the need for health care professionals will increase. The Association of American Medical Colleges estimates that the health care market will fall short of demand by 45,000 primary care physicians in 2020. Many states do not allow advanced practice registered nurses (APRNs) to perform primary care duties to their full potential; however, University of Missouri researchers say APRNs can help relieve the shortage of healthcare workers and expand access to care for underserved populations. In a recently published study, MU Sinclair School of Nursing researchers, Gina Oliver, Lila Pennington, Sara Revelle and Marilyn Rantz, found that quality of health care is improved in states where APRNs are allowed to practice independently.
Platelet transfusions increase odds of death in some rare blood cell disorders People hospitalized with certain rare blood cell disorders frequently receive a treatment that is associated with a two- to fivefold increase in death, according to a new study that reviewed hospital records nationwide. The study authors recommend that for these rare disorders, doctors should administer the treatment, a platelet transfusion, only in exceptional circumstances.
	Brazil approves marijuana derivative for medical treatment Brazil on Wednesday for the first time approved the use of a marijuana derivative to treat people suffering from severe seizures and other conditions.
US approves new weight-loss device for obese people US regulators on Wednesday approved a new kind of pacemaker-like device that aims to help people lose weight by stimulating a nerve that runs from the brain to the stomach.
Debunking aging myths in financial decisions Growing older leaves many with a gloomy prognosis, namely that cognitive aging will slow the mind and the ability to make decisions. However, when it comes to making financial decisions, many baby boomers would be pleased to know that experience, knowledge, and expertise can compensate for the challenges that age-related deterioration present in finance, according to new research from Columbia Business School.The study, "Sound Credit Scores and Financial Decisions Despite Cognitive Aging" recently published in the journal, Proceedings of the National Academy of Sciences (PNAS), found evidence that "crystallized intelligence," which is gained through experience and accumulated knowledge, can be more important that "fluid intelligence," the ability to think logically and process new information.
Lab creates pint-size weapon in pancreatic cancer fight Long Island scientists have developed miniature pancreatic "organoids" that for the first time provide investigators with living three-dimensional models of the human gland to aid understanding of pancreatic cancer and ways to stop it.
Dangerous 'poppers' contain toxic aerosol chemicals While it is widely known that "huffing" -  inhaling organic solvents or propellants to achieve a "high" - is extremely dangerous, new products being sold as "poppers" and distributed throughout the US,  primarily to men who have sex with men (MSM), actually contain harmful solvents and propellants and pose the same health risks as huffing. In their article titled "Sometimes Poppers Are Not Poppers: Huffing as an Emergent Health Concern among MSM Substance Users", authors Timothy M. Hall MD PhD, Steven Shoptaw PhD, and Cathy J. Reback PhD point out that these products marketed as "poppers" are not equivalent to conventional poppers, which are based on alkyl nitrites and related to the medication amyl nitrite.
More birds culled as Taiwan battles worst avian flu in 10 years A major outbreak of avian flu in Taiwan has spread to 19 more farms with a total of 160,000 birds slaughtered in the island's worst bout of the disease in a decade, authorities said Wednesday.

This historic expansion of data sharing is made possible through collaboration with Johnson & Johnson.
	Nemours, Therapy Box create app for kids, adults with speech deficits to use own voices The UK-based Therapy Box has released the first app that allows people who have limited vocal ability or are losing their voices due to ALS and other disabling conditions to replace generic text-to-speech synthesis with a synthesizer based on their own voice. The app breaks new ground via the integration of ModelTalker, a program developed by Tim Bunnell, PhD and colleagues at the Nemours Speech Research Laboratory in Wilmington, DE.
IOM report proposes standards for sharing clinical trial data Stakeholders in clinical trials should foster a culture in which data sharing is the expected norm and commit to responsible strategies aimed at maximizing the benefits, minimizing the risks, and overcoming the challenges of sharing data, says a new report from the Institute of Medicine. The report lays out recommended guidelines about which data from a clinical trial should be shared and when, such as the analytic data set that supports publication of results should be shared no later than six months after publication and the full analyzable data set should be shared no later than 18 months after study completion or 30 days after regulatory approval.
NIH expands early-stage human testing of infectious disease treatment candidates The National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, has awarded contracts to three organizations to support early-stage human clinical trials of investigational infectious disease treatments. The new awards for the Phase I Clinical Trial Units for Therapeutics increases the number of funded organizations under the program from two to three, expanding capacity for conducting early safety testing of novel investigational drugs.
Endobronchial forceps effective in retrieval of tip-embedded inferior vena cava filters When retrievable inferior vena cava (IVC) filters were approved for use in the United States in 2003 to prevent pulmonary embolism among patients unable to receive the standard blood thinner treatment, many experts anticipated most of them would be removed when no longer needed and IVC filter complications would decrease. Instead, the number of IVC filters placed has more than doubled in the last 10 years, and by some estimates, less than half of these retrievable devices are actually removed each year. Leaving the devices in place risks filter fracture or symptoms from penetration of filter components outside of the vein into adjacent structures, increased risk of new blood clots in the legs, and other complications.
