Astronomy & Space news

	New instrument reveals recipe for other Earths How do you make an Earth-like planet? The "test kitchen" of Earth has given us a detailed recipe, but it wasn't clear whether other planetary systems would follow the same formula. Now, astronomers have found evidence that the recipe for Earth also applies to terrestrial exoplanets orbiting distant stars.
	Super-Earths have long-lasting oceans For life as we know it to develop on other planets, those planets would need liquid water, or oceans. Geologic evidence suggests that Earth's oceans have existed for nearly the entire history of our world. But would that be true of other planets, particularly super-Earths? New research suggests the answer is yes and that oceans on super-Earths, once established, can last for billions of years.
	Stars' spins reveal their ages When you're a kid every birthday is cause for celebration, but as you get older they become a little less exciting. You might not want to admit just how old you are. And you might notice yourself slowing down over the years. You're not alone - the same is true of stars. They slow down as they age, and their ages are well-kept secrets. Astronomers are taking advantage of the first fact to tackle the second and tease out stellar ages.
	NASA explores inflatable spacecraft technology (Update) Devising a way to one day land astronauts on Mars is a complex problem and NASA scientists think something as simple as a child's toy design may help solve the problem. Safely landing a large spacecraft on the Red Planet is just one of many engineering challenges the agency faces as it eyes an ambitious goal of sending humans into deep space later this century.
Before explosion, NASA knew aging Soviet engines could crack and leak fuel Years before an unmanned rocket erupted in a fireball in October, NASA officials knew the metal in its 50-year-old Soviet-made engines could crack, causing fuel to leak and ignite, government documents show.
	Technology innovations spin NASA's SMAP into space t's active. It's passive. And it's got a big, spinning lasso.
	Image: Hubble sees an ancient globular cluster This image captures the stunning NGC 6535, a globular cluster 22,000 light-years away in the constellation of Serpens (The Serpent) that measures one light-year across.
	New analyses of Martian chemical maps suggest water bound to sulfates in soil A research team led by LSU Geology and Geophysics Assistant Professor Suniti Karunatillake reveals a spatial association between the presence of sulfur and hydrogen found in martian soil. The work by this multi-institutional team of researchers from Georgia Tech (James Wray), Stony Brook University (Scott McLennan and Deanne Rogers), CNRS/ Université Fédérale Toulouse Midi-Pyrénées (Olivier Gasnault), Cornell University (Steve Squyres), and University of Arizona (William Boynton) may in turn identify hydrous iron sulfates as key carriers of H2O in bulk martian soil. The gamma spectral signature of hydrogen serves as a possible indicator of water, a primary driver of weathering and life processes on Earth.
	Comet probe 'may revive in March', French space chief says A probe that made the first landing on a comet but fell silent when its battery ran down may revive with sunlight in March, France's space chief said Monday.
	SpaceX to try ocean platform landing of Falcon rocket SpaceX aims to launch a new era in modern rocket science Tuesday by landing a key part of its Falcon 9 rocket on a barge in the Atlantic Ocean.
	Image: Solar coronal hole welcomes the new year There were no fireworks on the sun to welcome in the New Year and only a few C-class flares during the last day of 2014. Instead, the sun starts 2015 with an enormous coronal hole near the south pole. This image, captured on Jan. 1, 2015 by the Atmospheric Imaging Assembly (AIA) instrument on NASA's Solar Dynamics Observatory, shows the coronal hole as a dark region in the south.
	Image: Space simulation chamber prepared for testing Webb telescope This photo was captured from outside the enormous mouth of NASA's giant thermal vacuum chamber, called Chamber A, at Johnson Space Center in Houston.
	Tracking the night sky for January 2015 Jupiter will dominate the night during January from the time it rises until dawn, soaring high across the sky in the constellation Leo the Lion about 10 degrees northwest of Leo's brightest star, Regulus.
	How did we find the distance to the sun? How far is the Sun? It seems as if one could hardly ask a more straightforward question. Yet this very inquiry bedeviled astronomers for more than two thousand years.
	Video: What is the biggest thing in the universe? Think big. Really big. Like, cosmic big. How big can things in the Universe get? Is a galaxy big? What about a supercluster? What is the biggest thing in the Universe?
	Rogue star HIP 85605 on collision course with our solar system, but Earthlings need not worry It's known as HIP 85605, one of two stars that make up a binary in the Hercules constellation roughly 16 light years away. And if a recent research paper produced by Dr. Coryn Bailer-Jones of the Max Planck Institute for Astronomy in Heidelberg, Germany is correct, it is on a collision course with our Solar System.

Medicine & Health news

	More effective diet pill: 'Imaginary meal' tricks the body into losing weight Salk researchers have developed an entirely new type of pill that tricks the body into thinking it has consumed calories, causing it to burn fat. The compound effectively stopped weight gain, lowered cholesterol, controlled blood sugar and minimized inflammation in mice, making it an excellent candidate for a rapid transition into human clinical trials.
	Rotating night shift work can be hazardous to your health Night shift work has been consistently associated with higher risk for cardiovascular disease (CVD) and cancer. In 2007 the World Health Organization classified night shift work as a probable carcinogen due to circadian disruption. In a study in the current issue of the American Journal of Preventive Medicine, researchers found that women working rotating night shifts for five or more years appeared to have a modest increase in all-cause and CVD mortality and those working 15 or more years of rotating night shift work appeared to have a modest increase in lung cancer mortality. These results add to prior evidence of a potentially detrimental effect of rotating night shift work on health and longevity.
	Fructose more toxic than table sugar in mice When University of Utah biologists fed mice sugar in doses proportional to what many people eat, the fructose-glucose mixture found in high-fructose corn syrup was more toxic than sucrose or table sugar, reducing both the reproduction and lifespan of female rodents.
	Women, quitting smoking for New Years? Time it with your period The menstrual cycle appears to have an effect on nicotine cravings, according to a new study by Adrianna Mendrek of the University of Montreal and its affiliated Institut universitaire en santé mentale de Montréal.
	'Small screens' prevent kids from sleeping, study says Children who have access to tablets or smartphones in their bedrooms get less sleep than children who do not have the devices with them at night, a US study said Monday.
	Pair finds lawyers with deep voices less likely to win cases at Supreme Court (Medical Xpress)—A pair of researchers, Alan Yu of the University of Chicago who is a linguist and Daniel Chen who studies legal theory at ETH Zurich in Switzerland has found, via a study they conducted, that lawyers with higher, less masculine voices, tend to have a better chance of winning a case presented to the U.S. Supreme Court than do those with deeper voices. The two will be presenting their findings to attendees at this year's Linguistic Society of America meeting in Portland later this month.
	Researchers find the missing part of brain's 'internal compass' If you have taken a walk and would like to return home you need to have an idea of where you are in relation to your destination. To do this, you need to know which way you are facing and also in which direction home lies. This all seems fairly instinctive to humans and other animals, so how do we manage it?
	Cold virus replicates better at cooler temperatures The common cold virus can reproduce itself more efficiently in the cooler temperatures found inside the nose than at core body temperature, according to a new Yale-led study. This finding may confirm the popular yet contested notion that people are more likely to catch a cold in cool-weather conditions.
	Study IDs risk factors linking low birthweight to diabetes A new study of more than 3,000 women confirms that low birthweight predicts an increased risk of type 2 diabetes in adulthood and reports which intermediating biomarkers appear to be the best predictors. The research could help physicians better assess patient risk.
	Whole plant therapy shows promise to beat malaria parasites' drug resistance For decades, physicians and public health officials worldwide have been thwarted by the malaria parasite's ability to evolve resistance to the succession of drugs developed to treat it. But now University of Massachusetts Amherst microbiologist Stephen Rich and his research team report an effective and sustainable malaria intervention that shows great promise in laboratory models.
	Epigenomics analysis reveals surprising new clues to insulin resistance In studying the cellular structure and function of insulin, a research team led by investigators at Beth Israel Deaconess Medical Center (BIDMC) has uncovered previously unknown steps in the development of insulin resistance, a hallmark of type 2 diabetes. Reported in the January 2015 issue of Nature Cell Biology, their surprising new findings identify two transcription factors—the glucocorticoid receptor (GR) and the vitamin D receptor (VDR) - that play a key role in insulin resistance, providing some of the first evidence that changes in the cellular nucleus underlie the condition and offering a promising new route for the development of drug therapies for type 2 diabetes.
	Animal study points to a treatment for Huntington's disease By adjusting the levels of a key signaling protein, researchers improved motor function and brain abnormalities in experimental animals with a form of Huntington's disease, a severe neurodegenerative disorder. The new findings may lay the groundwork of a novel treatment for people with this fatal, progressive disease.
Skin microbes trigger specific immune responses New research in mice shows that the immune system in the skin develops distinct responses to the various microbes that naturally colonize the skin, referred to as commensals. A team led by scientists at the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, found that each type of microbe triggers unique aspects of the immune system, suggesting that immune cells found in the skin can rapidly sense and respond to changes in microbial communities.
	Imaging linking cell activity and behavior shows what it means for mice to have sex in mind Most people have seen fMRI scans of the human brain. These use a technology called functional magnetic resonance imaging to identify portions of the brain that are active while a subject is being scanned. Fuzzy, ill-defined areas that "light up" on the scans indicate where neurons are active, based on magnetic changes in the blood that correlate with activated cells' need for glucose, their energy supply.
	Diabetes debate: Triglycerides form in liver despite insulin resistance Solving one of the great mysteries of type 2 diabetes, a team of Yale researchers found that triglycerides, a type of fat in the blood and liver, are produced in the liver independent of insulin action in the liver.
	Major study of bereaved military families underway With his wife and child close at hand, Army Maj. Chad Wriglesworth battled skin cancer for more than a year before dying at age 37.
Another drug is approved to help the obese The Food and Drug Administration has approved a drug that may be help some of the millions of Americans resolving to lose weight this year.
Small change in blood acidity could prove detrimental to kidney disease patients (Medical Xpress)—A University of Manchester scientist has discovered that very small changes in the level of acidity in blood may have a detrimental impact on the health of patients with kidney disease.
The power of mental visualization in maintaining real-life muscle Anyone who has worn a cast knows that rebuilding muscle strength once the cast is removed can be difficult. Now researchers at the Ohio Musculoskeletal and Neurological Institute (OMNI) at Ohio University have found that the mind is critical in maintaining muscle strength following a prolonged period of immobilization and that mental imagery may be key in reducing the associated muscle loss.
	Poor sleep causes weight gain and susceptibility to diabetes People who suffer breathing and heart rate abnormalities, called obstructive sleep apnea, are likely to develop diabetes, and the risk increases if they have a hereditary proclivity.
New study examines criminal behavior in patients with neurodegenerative diseases Criminal behavior can occur in patients with some neurodegenerative diseases, although patients with Alzheimer disease (AD) were among the least likely to commit crimes, according to a study published online by JAMA Neurology.
	More whole grains associated with lower mortality, especially cardiovascular Eating more whole grains appears to be associated with reduced mortality, especially deaths due to cardiovascular disease (CVD), but not cancer deaths, according to a report published online by JAMA Internal Medicine.
	Stress can be a factor for developing diabetes and autoimmune diseases Over time, recurrent stress can trigger insulin resistance, hypertension, and abdominal fat deposition, researchers have found.
Health-promoting Nordic diet reduces inflammatory gene activity in adipose tissue A Nordic study led by the Institute of Public Health and Clinical Nutrition at the University of Eastern Finland discovered that the health-promoting Nordic diet reduces the expression of inflammation-associated genes in subcutaneous adipose tissue. In overweight persons, the expression of these genes reduced without weight loss. To a certain extent, the adverse health effects of overweight are believed to be caused by an inflammatory state in adipose tissue. The results were published in the American Journal of Clinical Nutrition.
	The man who revolutionized our knowledge of the human body December 31, 2014 marks the 500th anniversary of the birth of one of the most important figures in the history of medicine. He authored one of the most elegant and influential books in scientific history. His investigations revolutionized our understanding of the interior of the human body and the methods physicians use to study and teach about it, reverberating throughout medicine down to the present day.

	'Magic' blood test simply a matter of science A blood-typing test based on bioactive paper has enormous implications for use in the developing world and poor and remote regions.
	For most 'healthy' obese, health declines over time The idea of "healthy" obesity is a misleading concept in that most obese individuals become progressively less healthy over time, according to a study that tracked the health of more than 2,500 men and women for 20 years. The research was published online today in the Journal of the American College of Cardiology.
	A healthy lifestyle may prevent heart disease in nearly three out of four women A new study that followed nearly 70,000 women for two decades concluded that three-quarters of heart attacks in young women could be prevented if women closely followed six healthy lifestyle practices.
Public reporting on quality slows price increases for bypass surgery and other hospital procedures A public reporting website that allows insurance companies and others to compare hospitals based on quality has injected a dose of competition into negotiations on the hospital prices for common procedures, according to a first-of-a-kind study out today in the January issue of Health Affairs. Avi Dor, a professor of health policy and management at Milken Institute School of Public Health at the George Washington University and colleagues, looked at the impact of Medicare's Hospital Compare website on actual hospital prices, finding that the public reporting initiative appears to have slowed price increases for two kinds of major cardiac procedures.
	Infections increase death risk by 35 percent for ICU patients, study finds Elderly patients admitted to intensive care units (ICUs) are about 35 percent more likely to die within five years of leaving the hospital if they develop an infection during their stay, a new study finds. Preventing two of the most common health care-acquired infections - sepsis caused by central lines and pneumonia caused by ventilators - can increase the odds that these patients survive and reduce the cost of their care by more than $150,000.
Radiation plus hormone therapy prolongs survival for older men with prostate cancer Adding radiation treatment to hormone therapy saves more lives among older men with locally advanced prostate therapy than hormone therapy alone, according to a new study in the Journal of Clinical Oncology this week from Penn Medicine researchers.
	Overly conservative FDA label likely prevents use of metformin in many type 2 diabetics Many patients with type 2 diabetes in the United States may be discouraged from taking metformin—a proven, oral diabetes medicine—because the U.S. Food and Drug Administration inappropriately labels the drug unsafe for some patients also suffering from kidney problems, researchers from Penn Medicine and Weill Cornel Medical College report this week in a research letter published in JAMA Internal Medicine.
	Higher altitude not necessarily better for athlete training Sports scientists have demonstrated that sprint training at a simulated altitude of 4000m results in poorer training performance, suggesting that a moderate altitude may give the greatest benefit to team sport athletes.
	Support, childcare needed for mothers of kids with intellectual disability Extra support, education and childcare services are needed to address a high rate of mental health problems in mothers of children with intellectual disabilities, research suggests.

	Chronic high blood pressure increases risk of glaucoma A new study published in Investigative Ophthalmology & Visual Science (IOVS) has found that chronic (long term) hypertension increases a person's susceptibility to glaucoma. These results suggest that doctors should consider a patient's blood pressure levels in managing the potentially blinding eye disorder.
	Patent granted for new technology diagnosing cancer A new diagnostic technology may significantly improve early detection and treatment of cancer and other diseases. Via a simple blood test the method can potentially diagnose diseases such as cancer at an early stage, enable screening of healthy individuals at risk of developing cancer, and help plan an individual course of treatment. Aarhus University has just received a patent for the technology in the USA.
Cancer prevention guidelines may lower risk of obesity-linked cancers Low alcohol consumption and a plant-based diet, both healthy habits aligning with current cancer prevention guidelines, are associated with reducing the risk of obesity-related cancers, a New York University study shows. The findings appear in the journal Cancer Causes & Control.
A human enzyme (CD 39) targets the Achilles heel of sepsis There may never be a way to completely prevent infection, but sepsis may have an Achilles heel that would allow for more effective treatment of the condition. In a new report published in the January 2015 issue of the FASEB Journal, scientists use mice to show that a human membrane-bound enzyme called CD39, which can clear the dangerous buildup of adenosine triphosphate (ATP) from the bloodstream, significantly improves survival of mice in sepsis. In addition to sepsis, the researchers speculate that CD39 may also be used in other diseases associated with inflammation, such as trauma, hemorrhagic shock and burns.
Researchers discover byproducts from bacteria in gum disease can awaken dormant T-cells and HIV viruses Dental and medical researchers from Case Western Reserve University found another reason to treat periodontal disease as soon as possible.
Gamma-Delta T cells may play a role in insulin resistance and type 2 diabetes New research in mice suggests that an unusual type of immune cell called "γδ T cells" may be a new drug and research target for treating or preventing type 2 diabetes caused by obesity. The research report, appearing in the January 2015 issue of the Journal of Leukocyte Biology, suggests that γδ T cells are necessary for obesity-induced accumulation of macrophages, which are associated with promoting inflammation in fat tissue. This inflammation, which is induced during obesity, is known to be a risk factor for insulin resistance and type 2 diabetes, but its underlying causes have not been clear.
Melanoma: Scientists find new link between pigment production and mitochondrial function A new research report published in the January 2015 issue of the FASEB Journal helps explain what goes wrong to when someone gets skin cancer and the relationship between changing skin pigment and the cancer itself. In particular, this research shows that there is a direct link between changes in mitochondrial function and melanin production in cancerous skin cells. This link may also serve as a viable drug target for the disease.
Exposure to cold reveals the 'switch' that controls the formation of brown and white fat The roles that white fat and brown fat play in metabolism is well documented, but new research published in the January 2015 issue of the FASEB Journal presents a new wrinkle: each type of fat may change into the other, depending on the temperature. In particular, cold temperatures may encourage "unhealthy" white fat to change into "healthy" brown fat.
Infection control preparedness measures control avian flu in Hong Kong hospital A proactive infection prevention plan implemented widely in a Hong Kong healthcare system was a significant factor preventing the spread of influenza strain A H7N9, otherwise known as Avian flu. The study was published in the January issue of Infection Control and Hospital Epidemiology, the journal of the Society for Healthcare Epidemiology of America (SHEA).
Hold your breath to protect your heart Women who have breast cancer on their left side present a particular challenge to radiation oncologists. Studies have shown that the risk of heart disease is higher in this group of women after radiation treatment because it can be difficult to ensure that a sufficient dose of radiation is delivered to the left breast while adequately shielding the heart from exposure. New research shows a woman who holds her breath during radiation pulses can greatly reduce radiation exposure to the heart.
	For men, income linked to changes in bone mineral density (HealthDay)—For men, income, but not self-identified race/ethnicity or genetic ancestry, is associated with annualized percentage changes in bone mineral density (BMD), according to a study published in the December issue of the Journal of Bone and Mineral Research.

Vitamin B may counter negative effect of pesticide on fertility Women who have adequate levels of B vitamins in their bodies are more likely to get and stay pregnant even when they also have high levels of a common pesticide known to have detrimental reproductive effects, according to new Johns Hopkins Bloomberg School of Public Health research.
A novel biomarker for mutant p53 could help pathologists assessing tumors during surgery Researchers at Cold Spring Harbor Laboratory (CSHL) today report the discovery of a novel cellular biomarker that could make it comparatively easy for cancer surgeons to determine if a patient has a potentially lethal mutation in a protein called p53, the most powerful of the body's natural tumor suppressors and often called "the guardian of the genome."
Mom's exercise habits good for blood pressure in kids It's been well established among doctors and researchers alike, that babies with lower birth weight have a greater risk of having high blood pressure later in life.
Alcohol taxes protective against binge drinking, study shows Higher alcohol taxes strongly protect against binge drinking, according to a new study by Boston University School of Public Health (BUSPH) researchers.
Human speech's surprising influence on young infants America's preoccupation with the "word gap"— the idea that parents in impoverished homes speak less to their children, which, in turn, predicts outcomes like school achievement and income later in life—has skyrocketed in recent years, leading to a rise in educational initiatives aiming to narrow the achievement gap by teaching young children more words.
	Nutrition education may help prevent breast cancer reoccurrence Breast cancer is the most frequent cause of death among women worldwide, and five-year survival rates are just 58.4% in Brazil, lower than in many other regions. In a new study, however, researchers from Federal University of Santa Catarina provided Brazilian breast cancer patients with nutrition education and found it could benefit patients and may help prevent reoccurrence of the cancer.

Geographic information helps provide public health intelligence at mass gatherings Infectious diseases are one of the many health issues that worry the organizers of mass gatherings, such as the Hajj and the World Cup. Geographers' tools of the trade can help event organizers to better plan, monitor and respond timely to such eventualities. The ways in which geographers gather, analyze, and visualize information provide health officials with clearer pictures of the transport routes and environmental factors that may further the spread of viruses to and from the attendees' home countries. In Chapter 3 of the new book Health, Science, and Place: A New Model, geographer and biologist Dr. Amy Blatt explains how geographic information is used for disease surveillance at mass gatherings.
Ouch! When teeth and hands connect, bites may be beastly Hand injuries are frequently caused by human and animal bites, prompting as many as 330,000 emergency department visits in the United States each year.
