Astronomy & Space news

	Are asteroid fragments drifting around a distant white dwarf star? (Phys.org)—WD 1145+017, a white dwarf star located some 570 light years from the Earth, captured the attention of astronomers last year, when evidence suggested that a rocky object orbiting it was being ripped apart. It was the first discovery of a planetological body transiting a white dwarf. Now, a team of astronomers lead by Saul Rappaport of the Massachusetts Institute of Technology (MIT), unveils evidence that the mysterious object is an asteroid and its fragments are drifting around this dense star remnant. A paper describing the new findings was published online on Feb. 1 in the arXiv journal.

	NIST performs critical measurements for James Webb Space Telescope The National Institute of Standards and Technology (NIST) has accurately measured parts designed for the upcoming James Webb Space Telescope, the long-awaited successor to the Hubble Space Telescope. The NIST-measured composite titanium and stainless steel parts, which support the skeleton for the telescope's massive mirror, will be used in the final round of NASA's vibration tests on the mirror assembly before the telescope's scheduled launch in October 2018.
	Astrophysicists use new methods to simulate the common-envelope phase of binary stars When we look at the night sky, we see stars as tiny points of light eking out a solitary existence at immense distances from Earth. But appearances are deceptive. More than half the stars we know of have a companion, a second nearby star that can have a major impact on their primary companions. The interplay within these so-called binary star systems is particularly intensive when the two stars involved are going through a phase in which they are surrounded by a common envelope consisting of hydrogen and helium. Compared to the overall time taken by stars to evolve, this phase is extremely short, so astronomers have great difficulty observing and hence understanding it. This is where theoretical models with highly compute-intensive simulations come in. Research into this phenomenon is relevant understanding a number of stellar events such as supernovae.
	James Webb Space Telescope primary mirror fully assembled The 18th and final primary mirror segment is installed on what will be the biggest and most powerful space telescope ever launched.

Medicine & Health news

	New study indicates why children are likelier to develop food allergies An estimated 15 million Americans suffer from food allergies, many of them children. These are non-trivial concerns, as food allergy or intolerance can cause symptoms ranging from a harmless skin rash to a potentially lethal anaphylactic shock. The good news is that many affected children outgrow their allergy, presumably as the immune system learns to tolerate food initially mistaken as "foreign".
Connective tissue disease increases risk for cardiovascular problems A study based on medical records from more than a quarter million adult patients found that African-American patients with connective tissue diseases such as lupus or rheumatoid arthritis were twice as likely as white patients to suffer from narrowed or atherosclerotic blood vessels, which increase the risk of a heart attack, stroke or death.
	Scientists uncover neural pathway responsible for opioid withdrawal In addition to the desire to experience a "high," one of the obstacles drug addicts encounter is the difficulty of overcoming a myriad of harsh withdrawal symptoms including anxiety, depression, nausea, vomiting and diarrhea. When people learn to associate the loss of drug use with the pain of withdrawal, it can create an urge to use that is as strong as the "high" itself, making it even more difficult to quit.
	New clues to common and elusive KRAS cancer gene One of the most common cancer-causing genes has continuously stymied researchers' efforts to develop treatments against it.
	Stopping tumor cells killing surrounding tissue may provide clue to fighting cancer Cancer cells kill off surrounding cells to make room to grow, according to new research from the University of Cambridge. Although the study was carried out using fruit flies, its findings suggest that drugs to prevent, rather than encourage, cell death might be effective at fighting cancer - contrary to how many of the current chemotherapy drugs work.
	Removing race from human genetic research A group of scientists are urging their colleagues to take a step forward and stop using racial categories when researching and studying human genetics.
	Individuals' medical histories predicted by their noncoding genomes, study finds Identifying mutations in the control switches of genes can be a surprisingly accurate way to predict a person's medical history, researchers at the Stanford University School of Medicine have found.

Improvised naloxone nasal sprays lack evidence of absorption and effect Naloxone hydrochloride is a medication that can reverse the effects of an opioid overdose. First responders (peers, family, police, etc.) may prefer nasal sprays to injectable naloxone, which has led to widespread use of improvised naloxone kits with atomisers for nasal delivery of the drug. On 18 November 2015, the US Food and Drug Administration (FDA) approved a nasal naloxone product to replace those improvised kits.
Tool decreases superfluous lab testing, cuts health-care costs Anyone who's spent a night in a hospital knows the drill: In comes a phlebotomist, first thing in the morning, for lab tests. Physicians have long recognized that lab testing isn't necessary for all hospitalized patients on a daily basis. Regardless, such tests are often conducted because of routine.
For pregnant women with flu, the earlier the better for antiviral treatment Pregnant women are at higher risk for serious illness and complications, including death, from influenza. For expectant mothers hospitalized with flu, early treatment with the influenza antiviral drug oseltamivir may shorten their time in the hospital, especially in severe cases, suggests a new study published in The Journal of Infectious Diseases and available online. The findings also underscore the importance of flu vaccination for this risk group.
	Have national smoking bans worked in reducing harms in passive smoking? The most robust evidence yet, published today in the Cochrane Library, suggests that national smoking legislation does reduce the harms of passive smoking, and particularly risks from heart disease. The updated Cochrane review containing more up-to-date research found that countries who imposed smoking bans found their populations benefited from reduced exposure to passive smoke, specifically cardiovascular disease.

	Tuning macrophages a 'breakthrough' in cancer immunotherapy Similar to stem cells differentiating to make your body's tissues, the immune system's macrophages pick a life path, differentiating into macrophages that recruit resources for wound repair or macrophages that recruit resources for wound sterilization. An article in the journal Cancer Research describes the relevance of macrophages to cancer: Cancers encourage macrophages to pick the path of wound-repair, making what are called "M2" or "repair-type" macrophages. Cancers use these M2 macrophages to promote their own growth. However, researchers can now successfully flip M2 macrophages into their wound-sterilizing cousins, called "M1" or "kill-type" macrophages, which, contrary to promoting the growth of new tissue, may aid the immune system in clearing the body of cancer. The article in this careful scientific journal calls this a "breakthrough".
	Team develops approach for identifying processes that fuel tumor growth in lung cancer patients Scientists at the Children's Medical Center Research Institute at UT Southwestern (CRI) have pioneered a new method for conducting in-depth research on malignant tumors in patients, in the process discovering new complexities underlying cancer biology and overturning a nearly century-old perception about cancer metabolism.

Patients with macular degeneration show improvement with high-dose statin treatment Researchers at Massachusetts Eye and Ear/Harvard Medical School and the University of Crete have conducted a phase I/II clinical trial investigating the efficacy of statins (cholesterol-lowering medications) for the treatment of patients with the dry form of age-related macular degeneration (AMD)—the leading cause of blindness in the developed world. Although effective treatments are available for the wet form of AMD, they are currently lacking for the more prevalent dry form. The researchers found evidence that treatment with high-dose atorvastatin (80mg) is associated with regression of lipid deposits and improvement in visual acuity, without progression to advanced disease, in high-risk AMD patients. Their findings were published in EBioMedicine—a new online journal led by editors of the journals Cell and The Lancet—and not only further the connection between lipids, AMD and atherosclerosis, but also present a potential t! herapy for some patients with dry AMD.

	Researchers hone in on why female newborns are better protected from brain injury Each year, thousands of newborn babies suffer complications during pregnancy or birth that deprive their brains of oxygen and nutrient-rich blood and result in brain injury. This deprivation results in hypoxic ischemic encephalopathy (HIE), which can lead to long-term neurological issues such as learning disabilities, cerebral palsy or even death.
Better quality of care may reduce risk of death for patients on opioid painkillers Better quality of care may reduce the risk of death for patients who are prescribed opioid painkillers for chronic pain, say Yale researchers. Their study, published Feb. 4 in the Journal of General Internal Medicine, offers evidence that supports recommendations from clinical practice guidelines encouraging physicians to engage patients with mental health services and substance abuse treatment, as well as to avoid co-prescriptions for sedatives.
Graphical display of nutrition information helps keep health-conscious eaters on target Diseases such as obesity, diabetes, and heart disease can often be prevented or treated by managing the intake of certain nutrients. However, in a time-constrained situation, such as standing in line at a cafeteria or restaurant, it can be difficult for consumers to quickly calculate and use numerical nutrition information—beyond the amount of calories—provided for menu items.

Syrian aid—lack of evidence for 'interventions that work', say researchers The lack of an evidence base in the donor-funded response to Syrian migrant crisis means funds may be allocated to ineffective interventions, say researchers, who call on funders and policymakers in London for this week's Syrian Donor Conference to insist on evaluation as a condition of aid.
	AGS guidance on diversity proves 'seeing' older patients is about more than seeing age New guidance from the American Geriatrics Society (AGS) aims to transform approaches to healthcare for our increasingly diverse older population. Developed by a committee of experts in ethnogeriatrics (the study of how ethnicity and culture impact the health and well-being of older people), "Achieving High-Quality Multicultural Geriatric Care" outlines present health disparities and the need for sensitivity to culture and health literacy when working with older individuals. As we look toward a not-so-distant future in 2050 when more than 80 million Americans will be 65-years-old or older, the factors outlined by AGS experts represent aspirational hallmarks of health care for a nation where "minorities" will soon account for nearly 40 percent of all older adults.
New edition of landmark neurology textbook For 26 years, the classic neurology textbook Bradley's Neurology in Clinical Practice has been an essential resource for practicing neurologists and trainees.
Gambling is associated with 'risk-taking behavior' in young teens, study finds Gambling among young teens may be associated with increased use of alcohol, cigarettes, or marijuana according to a study that surveyed sixth- to eighth-graders in Italian schools. The research is reported in the February issue of the Journal of Developmental & Behavioral Pediatrics, the official journal of the Society for Developmental and Behavioral Pediatrics.
Health-care disparities contribute to delayed testicular cancer diagnosis in a transgender woman A family physician reports the case of a transgender woman whose testosterone levels rose unexpectedly while on feminizing hormones, leading eventually to a diagnosis of a rare, virilizing form of testicular cancer. The complex medical and psychosocial factors related to the care of transgender patients that contributed to the delay in diagnosis are examined in the study published in LGBT Health.
Emerging vascular risk factors in women: Any differences from men? The incidence and severity of both traditional and emerging cardiovascular disease (CVD) risk factors as well as the response to treatment may differ between genders. In this narrative review, several emerging CVD risk factors (i.e. inflammatory and haemostatic markers, endothelial dysfunction, homocysteine, lipid disorders, microalbuminuria/proteinuria, coronary artery calcium score, arterial stiffness, periodontitis, inflammatory bowel syndrome, obstructive sleep apnea, impaired glucose metabolism, metabolic syndrome and non-alcoholic fatty liver disease) are discussed in the context of gender differences.
Predicting periodontitis at state and local levels in the United States The International and American Associations for Dental Research (IADR/AADR) have published an article titled "Predicting Periodontitis at State and Local Levels in the United States" in the OnlineFirst portion of the Journal of Dental Research. In it, authors P.I. Eke, X. Zhang, H. Lu, L. Wei, G. Thornton-Evans, K.J. Greenlund, J.B. Holt and J.B. Croft estimate the prevalence of periodontitis at state and local levels across the United States by using a novel, small area estimation (SAE) method.
Lack of research keeps end-of-life care in status quo Randomized controlled trials often are considered the gold standard of research studies that help guide the medical care of patients across the world. However, in hospices, randomized controlled trials are difficult to conduct since patients are so close to the end of their lives, causing a gap in research that could improve the quality of hospice care overall. Now, a University of Missouri School of Medicine researcher has found that only 10 randomized controlled trials have taken place in U.S. hospices since 1985. The researcher said more randomized trials by hospice researchers could lead to improved care for hospice patients.

Biology news

	Functional biological compass linked to light receptor protein (Phys.org)—Many animals including birds and insects have been observed to perceive geomagnetic fields. Past studies have demonstrated that cryptochrome/photolyase family (CPF) light receptor proteins are involved in animal behavioral responses to the presence of geomagnetic fields, but so far, no studies have determined whether these proteins are linked with the direction of the magnetic field vector.
	Loss of wild flowers across Britain matches pollinator decline The first ever Britain-wide assessment of the value of wild flowers as food for pollinators, led by the University of Bristol, shows that decreasing resources mirror the decline of pollinating insects, providing new evidence to support the link between plant and pollinator decline.
	Bears' seasonal hibernation linked to changes in gut microbes Each year, as bears prepare to hibernate, they gorge themselves on food to pack on fat. And yet, despite the rapid weight gain, the animals somehow avoid the health consequences so often associated with obesity in humans. Now, researchers reporting in Cell Reports on February 4 show that the bears' shifting metabolic status is associated with significant changes in their gut microbes.
	Bee virus spread manmade and emanates from Europe The spread of a disease that is decimating global bee populations is manmade, and driven by European honeybee populations, new research has concluded.
	Study finds ratio between speed of evolution, population change Does evolution really trundle along like Darwin's famous Galapagos tortoise? And do the populations undergoing this evolution really grow and decline with the speed of a hare?
	Study finds half of attacks on people by large carnivores in the wild due to risky behavior (Phys.org)—A team of researchers from several countries in Europe and Canada has found that approximately half of all attacks on humans by large carnivores in the wild can be attributed at least in part, to risky behavior by those that have been attacked. In their paper published in Scientific Reports, the team describes the study they carried out, their results and their hope that better education will prevent more such attacks from happening in the future.
	The return of the flatworm Where does the acoel flatworm belong in the tree of life? Biologists have discussed this question for the last 20 years. Now Andreas Hejnol and his colleagues at the Sars Centre believe they have found the answer. The results are published in Nature.
	A newly discovered form of immunity helps explain how bacteria fight off viruses When seeking to protect themselves from viruses, some bacteria use a seemingly risky strategy: They wait until the invading virus has already begun to replicate. Research at The Rockefeller University shows how the microbes use two newly identified enzymes to fight off an infection even after delaying action.
	Molecular switch lets salmonella fight or evade immune system Researchers at the University of Illinois at Chicago have discovered a molecular regulator that allows salmonella bacteria to switch from actively causing disease to lurking in a chronic but asymptomatic state called a biofilm.
	Get a room! Tokyo zoo's bashful pandas try for a baby Two giant pandas at Tokyo's Ueno Zoo have been given some private time in a bid to create a romantic environment in which the bashful creatures can mate.
	Scientists overcome hurdles for champion racehorses Scientists at Queen Mary University of London (QMUL) are a step closer to preventing the kind of injuries that affect ageing race horses like champion hurdler Rock on Ruby, the winner of Coral Hurdle at Ascot in 2015.
	Scientists disable infectious bacteria by removing key protein Scientists at the John Innes Centre and the University of East Anglia have made an exciting discovery that could provide a new way to prevent bacterial infections in both humans and plants without triggering multi-drug resistance in bacteria.
	Making use of the head Move over metal fans—there's a new head-banging king in town.
	Researchers sequence first bedbug genome Scientists have assembled the first complete genome of one of humanity's oldest and least-loved companions: the bedbug. The new work, led by researchers at the American Museum of Natural History and Weill Cornell Medicine, and published Feb. 2 in Nature Communications, could help combat pesticide resistance in the unwelcome parasite. The data also provides a rich genetic resource for mapping bedbug activity in human hosts and in cities, including subways.
	Scientists boost lifespan of mice by deleting defective cells The ageing population is one of the greatest challenges facing society. More people are surviving to old age than ever before, but we currently lack the means to keep them healthy and independent. If a treatment existed to reduce sickness and death from ageing by 20% then between now and 2050, the US alone would save US$4 trillion on healthcare costs – enough money to give everyone on Earth clean drinking water for the next three decades.
How roots grow In contrast to animals, plants form new organs throughout their entire life, i.e. roots, branches, flowers and fruits. Researchers in Frankfurt wanted to know to what extent plants follow a pre-determined plan in the course of this process. In the renowned journal Current Biology, they describe the growth of secondary roots of thale cress (Arabidopsis thaliana). They have observed it cell by cell in a high-tech optical microscope and analysed it with computer simulations. Their conclusion: root shape is determined by a combination of genetic predisposition and the self-organization of cells.
	Australian parrots need more protection Australia has the world's highest diversity of parrots, but a new analysis by researchers at The Australian National University (ANU) has found the nation's record in conserving these beautiful birds leaves much to be desired.
	Seagrass doubles its chances in last-ditch reproductive strategy If you're faced with your own mortality you would do nearly anything to improve your chances of survival, right? So too for a species of seagrass called Posidonia australis that grows in Shark Bay.
	Insecticide increases effect of varroa mite Honeybees infected with the Varroa destructor mite have less stamina than those which have been effectively treated against the parasite. Additional exposure to the insecticide Imidacloprid further increases the harmful effect of the varroa mite. This was the conclusion of Wageningen UR scientists Lisa Blanken, Frank van Langevelde and Coby van Dooremalen as published in an article in the British Royal Society's magazine Proceedings B.
The odor of stones Diatoms are unicellular algae that are native in many waters. They are a major component of marine phytoplankton and the food base for a large variety of marine organisms. In addition, they produce about one fifth of the oxygen in the atmosphere and are therefore a key factor for our global climate. However, these algae, which measure only a few micrometers, have yet another amazing ability: they can "smell" stones.
	Satellite measurements of ocean color, temperature help researchers predict sturgeon locations Researchers at the University of Delaware are one step closer to developing an online map that would help Mid-Atlantic fishermen avoid catching Atlantic sturgeon.
	Rhino, tiger and snow leopard DNA found in Chinese medicines More should be done to stop the use of endangered species in traditional Chinese medicines, with snow leopard, tiger and rhinoceros DNA still being found in remedies, according to a leading University of Adelaide pathologist.
	The evolution of Dark-fly On November 11, 1954, Syuiti Mori turned out the lights on a small group of fruit flies. More than sixty years later, the descendents of those flies have adapted to life without light. These flies—a variety now known as "Dark-fly"—outcompete their light-loving cousins when they live together in constant darkness, according to research reported in the February issue of G3: Genes|Genomes|Genetics. This competitive difference allowed the researchers to re-play the evolution of Dark-fly and identify the genomic regions that contribute to its success in the dark.
Bachelor's paradise: Researcher finds female turtles outnumbering males Rising global temperatures may skew gender imbalance among the marine turtle population, according to new Florida State University research.
	Leading bugs to the death chamber: A kinder face of cholesterol Cells of our immune system kill pathogens by enclosing them in a compartment called the phagosome. The phagosome undergoes programmed maturation, where the pathogen is degraded. Intimately linked to this degradation is active transport of the phagosome inside cells by nanoscale "Motor" proteins such as Dynein and Kinesin, which are force generators for many kinds of biological movements.
In Boston area, the bald eagle population is soaring People spotting bald eagles in the skies over the Boston area aren't hallucinating—there really are more of the majestic birds of prey setting up shop in the urban eastern areas of the state, experts say.
	New tarantula named after Johnny Cash among 14 spider species found in the United States A new species of tarantula named after the famous singer-songwriter Johnny Cash is one of fourteen new spiders discovered in the southwestern United States. While these charismatic spiders have captured the attention of people around the world, and have been made famous by Hollywood, little was actually known about them. The new descriptions nearly double the number of species known from the region. Biologists at Auburn University and Millsaps College have described these hairy, large-bodied spiders in the open-access journal ZooKeys.
Data gaps hinder explanation for Alaska seabird die-off A preliminary investigation into the massive die-off of common murres, one of the Northern Hemisphere's most abundant seabirds, off Alaska's coast is revealing gaps in basic information on North Pacific waters and the wildlife that inhabit them.
	Study to develop new forensic methods for human DNA cases Sam Houston State University (SHSU) was awarded a grant from the National Institute of Justice (NIJ) to develop and test the best possible sample preparation methods for skeletal and decomposing human remains using emerging next generation DNA technology to help identify missing persons or victims of mass disasters.
	'Exploding' sugar beet cells for faster fermentation Sugar beet is an interesting raw material in the biobased economy as the sugars it contains can easily be fermented into valuable molecules. This does require a profitable process, however. The European ERA-NET innovation project ChemBeet is developing a very promising technology in which cells are exploded to create a faster and cheaper fermentation process.
	Key threats to siamese crocodiles and highlights lessons learned from 15 years of conservation work A new paper 'Status, distribution and ecology of the Siamese crocodile Crocodylus siamensis in Cambodia' (October 2015, Cambodian Journal of Natural History) reports that fewer than 400 wild Siamese crocodiles remain in Cambodia, following decades of poaching. However, the paper concludes that there are good prospects of rebuilding their populations by enlisting the help of indigenous communities and by releasing genetically-screened captive-bred stock
	One step closer to commercial edamame production in the US Edamame, touted as a healthy snack for its high protein content, is becoming increasingly popular in the United States. The soybean seeds are consumed at an immature stage, giving a sweet and slightly nutty flavor. Yet, despite the fact that grain soybean is grown on approximately 74 million acres in the U.S., the majority of edamame consumed here is imported from Asia. Part of the problem is that production practices, including weed control options, have not been well researched. A new University of Illinois study sheds light on weed management in edamame, bringing the crop one step closer to domestic cultivation.
	Whale washes ashore on British beach A sperm whale washed up in shallow water off a beach in Britain on Thursday, the 29th such stranding in Europe in the last two weeks.
