Astronomy & Space news

	Researchers find tidally distorted exoplanets may have unique signatures Astronomers could soon be able to find rocky planets stretched out by the gravity of the stars they orbit, according to a group of researchers in the United States. The team, led by Prabal Saxena of George Mason University, describe how to detect these exotic worlds in a paper in the journal Monthly Notices of the Royal Astronomical Society.
	MESSENGER data suggest recurring meteor shower on Mercury The closest planet to the sun appears to get hit by a periodic meteor shower, possibly associated with a comet that produces multiple events annually on Earth.
	Signs of ancient Mars lakes and quakes seen in new map Long ago, in the largest canyon system in our solar system, vibrations from "marsquakes" shook soft sediments that had accumulated in Martian lakes.
	MAVEN mission identifies links in chain leading to atmospheric loss Early discoveries by NASA's newest Mars orbiter are starting to reveal key features about the loss of the planet's atmosphere to space over time.
	Fermi brings deeper focus to thunderstorm gamma-rays Each day, thunderstorms around the world produce about a thousand quick bursts of gamma rays, some of the highest-energy light naturally found on Earth. By merging records of events seen by NASA's Fermi Gamma-ray Space Telescope with data from ground-based radar and lightning detectors, scientists have completed the most detailed analysis to date of the types of thunderstorms involved.
	Potentially hazardous asteroid surprises astronomers "Watch therefore, for ye know not the day nor the hour," could be still an actual description of our ability to predict asteroid threats to Earth. The sentence from the Bible (Matthew 25:13) sounds like a reminder of a vast number of more than 1,500 currently potentially hazardous objects, floating in space, meandering around in the Solar System. Some of them may be destined to pay our planet a close visit someday, unexpectedly, Chelyabinsk-style, as the one that hit Russia in February 2013, causing serious damages and injuring about 1,500 people. Who would have predicted that? Lately, one of the potentially hazardous asteroids, named 2014 UR116, created quite a buzz when various media reported that the 370 meters wide space rock may hit Earth. Its impact would cause an explosion 1,000 times greater than the Chelyabinsk meteor. But the discoverer of 2014 UR116, Vladimir Lipunov, a professor at Moscow State University, becalms the ! public. "This asteroid will not collide with Earth during the next 100 years," Lipunov told astrowatch.net.
	Engineering students aim to generate first breathable air on Mars A project by students from The University of Western Australia and Mars One astronaut candidate Josh Richards has reached the finals of an international competition to land vital experiments on the Red Planet.

	NASA image: Super Guppy spends a restful night in the NASA Langley hangar NASA's Super Guppy aircraft, designed to transport extremely large cargo, rests after making a special delivery to the NASA Langley Research Center in Hampton, Virginia. The aircraft measures more than 48 feet to the top of its tail and has a wingspan of more than 156 feet with a 25-foot diameter cargo bay – the aircraft features a hinged nose that opens 110 degrees.

Medicine & Health news

	Neuronal circuits filter out distractions in the brain The next time you are in a crowded room, or a meeting, or even at the park with your kids, take a look around. How many people are on their phone? Distractions invade every aspect of our lives. Status updates, text messages, email notifications all threaten to steal our attention away from the moment. While we fight the urge to check the phone, our brains are making constant judgment calls about where to focus attention. The brain must continually filter important information from irrelevant interference.
	Are you genetically predisposed to antisocial behavior? Both positive and negative experiences influence how genetic variants affect the brain and thereby behaviour, according to a new study. "Evidence is accumulating to show that the effects of variants of many genes that are common in the population depend on environmental factors. Further, these genetic variants affect each other," explained Sheilagh Hodgins of the University of Montreal and its affiliated Institut Universitaire en Santé Mentale de Montréal. "We conducted a study to determine whether juvenile offending was associated with interactions between three common genetic variants and positive and negative experiences." Hodgins and her colleagues published the study on December 11, 2014 in the International Journal of Neuropsychopharmacology.
	Neurotransmitter binding-site function revealed with unprecedented accuracy What does it take for a drug molecule to turn on a protein? Sometimes nothing more than jostling a few atoms. New research from University at Buffalo scientists will help pharmacologists better understand how drugs work and how to make them more effective.
	Brain stimulation may hold key to treating anxiety Researchers at The University of Western Australia have found that that brain stimulation may help retrain unhelpful cognitive habits associated with anxiety and depression. The paper was published today in the international journal Biological Psychiatry.
	Algorithm identifies networks of genetic changes across cancers The algorithm, called Hotnet2, was used to analyze genetic data from 12 different types of cancer assembled as part of the pan-cancer project of The Cancer Genome Atlas (TCGA). The research looked at somatic mutations—those that occur in cells during one's lifetime—and not genetic variants inherited from parents. The study identified 16 subnetworks of genes—several of which have not previously received much attention for their potential role in cancer—that are mutated with surprising frequency in the 3,281 samples in the dataset.
	Discovery may hold clues to treatments that slow aging In a study published today by Nature, researchers at Joslin Diabetes Center used a microscopic worm (C. elegans) to identify a new path that could lead to drugs to slow aging and the chronic diseases that often accompany it—and might even lead to better cosmetics.
	Virtual bodyswapping diminishes people's negative biases about others What if you could, for a moment, have the body of someone of a different race, age, or sex? Would that change the way you feel about yourself or the way that you stereotype different social groups? In a paper publishing online December 15 in the Cell Press journal Trends in Cognitive Sciences, researchers explain how they have used the brain's ability to bring together information from different senses to make white people feel that they were inhabiting black bodies and adults feel like they had children's bodies. The results of such virtual bodyswapping experiments are remarkable and have important implications for approaching phenomena such as race and gender discrimination.
Complex interactions between proteins Rbm38 and p53 govern tumor suppression, aging Scientists have long known the p53 protein suppresses tumors. However, a recent animal study by UC Davis researchers has uncovered a complicated relationship between p53 and another protein, Rbm38, highlighting how the body calibrates protein levels. Too much Rbm38 reduces p53 levels, increasing the risk of cancer. Too little Rbm38 allows p53 overexpression, causing premature aging. The study was published in the journal PNAS on Dec. 15.
	'Darwinian' test uncovers an antidepressant's hidden toxicity Because of undetected toxicity problems, about a third of prescription drugs approved in the U.S. are withdrawn from the market or require added warning labels limiting their use. An exceptionally sensitive toxicity test invented at the University of Utah could make it possible to uncover more of these dangerous side effects early in pharmaceutical development so that fewer patients are given unsafe drugs.
	Proteins drive cancer cells to change states A new study from MIT implicates a family of RNA-binding proteins in the regulation of cancer, particularly in a subtype of breast cancer. These proteins, known as Musashi proteins, can force cells into a state associated with increased proliferation.
	Making sense through order Cognitive scientists at the University of Rochester say they have an alternative to the standard explanation for why order matters when the human mind processes information. Instead of ignoring the order in which people receive information, they embrace it.
	Cake or carrots? Timing may decide what you'll nosh on When you open the refrigerator for a late-night snack, are you more likely to grab a slice of chocolate cake or a bag of carrot sticks? Your ability to exercise self-control—i.e., to settle for the carrots—may depend upon just how quickly your brain factors healthfulness into a decision, according to a recent study by Caltech neuroeconomists.
Long noncoding RNAs: A novel prognostic marker in older patients with acute leukemia A new study led by researchers at The Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC - James) describes a novel marker that might help doctors choose the least toxic, most effective treatment for many older patients with acute myeloid leukemia (AML). AML occurs mainly in older patients and has a three-year survival rate of 5 to 15 percent.
People with low numeracy feel negative about taking part in bowel cancer screening People who have problems with numbers may be more likely to feel negative about bowel cancer screening, including fearing an abnormal result, while some think the test is disgusting or embarrassing, according to a Cancer Research UK supported study published today in the Journal of Health Psychology.

In a new editorial published in the American Journal of Transplantation, experts explain how simple assessments of donors can help ensure that the organ supply is safe, while having little impact on the donor pool.
Medicare payment reform saves money, helps patients, study finds Researchers have found evidence that Medicare reimbursement reform has reduced the incidence of easily preventable, hospital-acquired health problems.
FDA approves drug that extends survival in the most common type of lung cancer The U.S. Food and Drug Administration today approved a new drug to treat non-small-cell lung cancer (NSCLC), offering patients new hope in fighting this difficult disease. Lung cancer is expected to lead to over 150,000 deaths in the United States this year alone, and NSCLC accounts for about 85 percent of all lung cancers.
	Report shows challenges for working families in transition off of public benefits Getting a better job or more hours at work should be a boon to low-income individuals who are trying to lift themselves and their families out of poverty. But sometimes, instead, their families suffer more just when they should begin to thrive.
	Antibiotics resistance could kill 10m a year by 2050 A British government-commissioned review has found that resistance to antibiotics could account for 10 million deaths a year and hit global gross domestic product by 2.0 to 3.5 percent by 2050.
	Researcher develops robotic surgery technique to treat previously inoperable head and neck cancer In a groundbreaking new study, UCLA researchers have advanced a robotic surgical technique to successfully access a previously unreachable area of the head and neck.
New floor covering can lead to breathing problems in babies New flooring in the living environment of pregnant women significantly increases the risk of infants to suffer from respiratory diseases in their first year of life. This is the result of a study carried out by the Helmholtz Centre for Environmental Research (UFZ) and the "St Georg" Municipal Hospital, which demonstrates that exposure to volatile organic compounds in the months before and after birth induces breathing problems in early childhood . The scientists therefore recommend that redecoration should be avoided during pregnancy or in the first year of children's life. According to an article written by the scientists in the scientific journal Environment International this could prevent at a rough estimate around 20,000 cases per year of wheezing requiring medical treatment in infants in Germany alone.
Skipping meals increases children's obesity and cardio metabolic risk Children who skip main meals are more likely to have excess body fat and an increased cardiometabolic risk already at the age of 6 to 8 years, according to a Finnish study. A higher consumption of sugary drinks, red meat and low-fat margarine and a lower consumption of vegetable oil are also related to a higher cardiometabolic risk. "The more of these factors are present, the higher the risk," says Ms Aino-Maija Eloranta, MHSc, who presented the results in her doctoral thesis at the University of Eastern Finland.
Lowering dietary fat intake reduces death rates in some women with breast cancer Among early-stage breast cancer patients who reduced their dietary fat intake for five years following a diagnosis, after over 15 years follow-up, death rates from all causes were significantly reduced in those who had hormone-unrelated breast cancer, according to data from the Women's Intervention Nutrition Study (WINS) presented at the 2014 San Antonio Breast Cancer Symposium, held Dec. 9–13.

Current practices in reporting on behavioural genetics can mislead the public "Media reports about behavioural genetics unintentionally induce unfounded beliefs, therefore going against the educational purpose of scientific reporting," writes the University of Montreal's Alexandre Morin-Chassé, following his study of 1,500 Americans. "Among other things, we wanted to know if the public understood (or misunderstood) popular science articles about a new research field, genopolitics, and whether this popularization indeed helped people have an informed opinion on human genetics," Morin-Chassé explained.
Novel agent decreases neuropathic pain in patients with type 2 diabetes Molecular Medicine, a peer-reviewed biomedical journal published by the Feinstein Institute Press, published the results of a new study reporting clinically significant pain reduction in type 2 diabetic patients. In an exploratory study conducted by Araim Pharmaceuticals, a biotech company developing novel treatments for chronic diseases, investigators also observed improvements in metabolic control in patients administered ARA 290. ARA 290 is a peptide engineered to activate the innate repair receptor, a receptor discovered by Araim scientists, which is only expressed following tissue damage or stress.
	Neurons listen to glia cells Scientists at Johannes Gutenberg University Mainz (JGU) in Germany have discovered a new signal pathway in the brain that plays an important role in learning and the processing of sensory input. It was already known that distinct glial cells receive information from neurons. However, it was unknown that these same glial cells also transmit information to neurons. The glia release a specific protein fragment that influences neuronal cross-talk, most likely by binding to the synaptic contacts that neurons use for communication. Disruption of this information flow from the glia results in changes in the neural network, for example during learning processes.
War metaphors for cancer hurt certain prevention behaviors It's not unusual for people to use war metaphors such as "fight" and "battle" when trying to motivate patients with cancer.
Faces that distract from actions The sudden appearance of a face within our visual field can affect the motor action accompanying a gesture even if the face is totally unrelated to what we are doing and even if we try to ignore it. At one condition, though: the face must display an emotionally significant expression. A study conducted by scientists of the International School for Advanced Studies in Trieste, and just published in Psychonomic Bullettin & Review, describes the phenomenon in detail.
Less than half of parents think their 18-year-olds can make a doctors appointment Most parents agree their children should be ready to move out of the pediatrician's office into adult-focused care by age 18 - but just 30 percent actually make that transition by that age, according to the University of Michigan C.S. Mott Children's Hospital National Poll on Children's Health.
