Astronomy & Space news

	Musk is testing x-wing style fins, spaceport drone ship (Phys.org) —Elon Musk over the weekend sent out a number of tweets about what's up at SpaceX in its rocket endeavors, talking about features that triggered a steady response stream of "Awesome," "Rad," and "Wow" reactions from Musk enthusiasts, eager to track the progress of the SpaceX reusable rocket program.
	How can we search for life on icy moons such as Europa? Our solar system is host to a wealth of icy worlds that may have water beneath the surface. The Cassini spacecraft recently uncovered evidence of a possible ocean under the surface of Saturn's moon, Mimas.
	Gas cloud in the galactic centre is part of a larger gas streamer (Phys.org) —In November, astronomers at the Max Planck Institute for Extraterrestrial Physics presented new observations of the gas cloud G2 in the galactic centre originally discovered in 2011. These data are in remarkably good agreement with an on-going tidal disruption. As a complete surprise came the discovery that the orbit of G2 matches that of another gas cloud detected a decade ago, suggesting that G2 might actually be part of a much more extensive gas streamer. This would also match some of the proposed scenarios that try to explain the presence of G2. One such model is that G2 is originating from the wind from a massive star.
	Time in space exposes materials to the test of time Much like that pickup truck rusting in your backyard thanks to time, rain and the elements, extended stays in the brutal environment of space can take its toll on spacecraft, satellites and space stations. In fact, anything outside the protective blanket of our atmosphere can be assaulted by orbital debris, temperature extremes, micrometeoroids, direct sunlight and, when spacecraft are in low-Earth orbit (LEO) or orbiting near another planet like Mars, atomic oxygen. Over time this relentless hammering by the space environment degrades many spacecraft materials.
	Rosetta Comet Landing in 'Thud' and 3D (Phys.org) —A 3D image shows what it would look like to fly over the surface of comet 67P/Churyumov-Gerasimenko. The image was generated from data collected by the Rosetta Lander Imaging System (ROLIS) aboard the European Space Agency's Philae spacecraft during the descent to the spacecraft's initial touchdown on the comet Nov. 12. The European Space Agency also released an audio track of the first of the lander's three touchdowns on the surface of the cometю
	Soyuz spacecraft docks with International Space Station A Russian Soyuz spacecraft carrying Italy's first female astronaut has safely docked with the International Space Station, NASA said.
	Lockheed Martin keeps fingers crossed for Orion's first test flight As we move closer to the highly anticipated first ever test flight of the Orion spacecraft, there's an aerospace company which would be keeping its fingers tightly crossed during this nail-biting moment for the U.S. spaceflight. Lockheed Martin which built the manned capsule that will take American astronauts far beyond Earth, is much more than excited about the milestone flight. "We live for this kind of project. We will tell our kids and our grandkids about this," Allison Rakes, Lockheed Martin spokesperson told Astrowatch.net. The company's hard working crew literally lives for this first step of future deep space exploration. "We've had a team in Florida working around the clock for the past several months preparing for this moment. Once that Delta IV lifts off, you're going to see quite the celebration," Rakes added.
	CubeSat instruments to demonstrate NASA firsts The Dellingr six-unit CubeSat, which is taking its developers just one year to design, build and integrate, won't be the only potentially groundbreaking capability for NASA. Its heliophysics payloads also are expected to significantly advance science on tiny platforms.
	Earth's orbit around the sun Ever since the 16th century when Nicolaus Copernicus demonstrated that the Earth revolved around in the Sun, scientists have worked tirelessly to understand the relationship in mathematical terms. If this bright celestial body – upon which depends the seasons, the diurnal cycle, and all life on Earth – does not revolve around us, then what exactly is the nature of our orbit around it?
	Image: Hubble captures the Egg Nebula This colourful image shows a cosmic lighthouse known as the Egg Nebula, which lies around 3000 light-years from Earth. The image, taken with the NASA/ESA Hubble Space Telescope, has captured a brief but dramatic phase in the life of a Sun-like star.

	Pain in a dish: Researchers turn skin cells into pain sensing neurons After more than six years of intensive effort, and repeated failures that made the quest at times seem futile, Harvard Stem Cell Institute (HSCI) researchers at Boston Children's Hospital (BCH) and Harvard's Department of Stem Cell and Regenerative Biology (HSCRB) have successfully converted mouse and human skin cells into pain sensing neurons that respond to a number of stimuli that cause acute and inflammatory pain.
	Brain's reaction to virtual reality should prompt further study, suggests new research UCLA neurophysicists have found that space-mapping neurons in the brain react differently to virtual reality than they do to real-world environments. Their findings could be significant for people who use virtual reality for gaming, military, commercial, scientific or other purposes.
	Schizophrenia may be triggered by excess protein during brain development A gene associated with schizophrenia plays a role in brain development and may help to explain the biological process of the disease, according to new Rutgers research.
	Mutant protein takes babies' breath away Babies start breathing in the womb, inhaling and exhaling irregularly at first, and then gradually more and more, until the day when they're born and have to do it all the time. But premature babies sometimes have trouble. They stop breathing periodically, sometimes for 20 or 30 seconds at a time. Sometimes they're fine, and sometimes they're not, and doctors struggle to help them. That may soon change, however, thanks to a two-month-old patient at UConn Health with a rare connexin mutation, and his doctor's willingness to call for help.
	The sound of status: People know high-power voices when they hear them Being in a position of power can fundamentally change the way you speak, altering basic acoustic properties of the voice, and other people are able to pick up on these vocal cues to know who is really in charge, according to new research published in Psychological Science, a journal of the Association for Psychological Science.
	Healthy gut microbiota can prevent metabolic syndrome, researchers say Promoting healthy gut microbiota, the bacteria that live in the intestine, can help treat or prevent metabolic syndrome, a combination of risk factors that increases a person's risk for heart disease, diabetes and stroke, according to researchers at Georgia State University and Cornell University. Their findings are published in the journal Gastroenterology.
	Motor coordination issues in autism are caused by abnormal neural connections Abnormal connections between neurons are the likely cause of motor coordination issues seen in autism spectrum disorder. Using a mouse model of autism, scientists from the University of Chicago identified a malfunctioning neural circuit associated with reduced capacity for motor learning. This appears to arise from an inability to eliminate unneeded neural connections in the brain. They report their findings Nov. 24 in Nature Communications.
	'Good fat' could help manage type 2 diabetes (Medical Xpress)—A special type of fat found in some people could be used to manage type 2 diabetes.
	New insights into how tumor-suppressing p53 binds to the human genome Scientists from the US Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have learned new details about how an important tumor-suppressing protein, called p53, binds to the human genome. As with many things in life, they found that context makes a big difference.
Scientists identify bone cells that could help children who need corrective facial surgery Our bones are smart. Bones know that by adolescence it's time to stop growing longer and stronger, and from that point on bones keep their shape by healing injuries.
	New research discovers gene that reduces risk of stroke Scientists have discovered a gene that protects people against one of the major causes of stroke in young and middle-aged adults and could hold the key to new treatments.
	Masking HIV target cells prevents viral transmission in animal model Cloaking immune cells with antibodies that block T cell trafficking to the gut can substantially reduce the risk of viral transmission in a non-human primate model of HIV infection, scientists report.
Excessive contact between cellular organelles disrupts metabolism in obesity Researchers at Harvard School of Public Health (HSPH) have found a novel mechanism causing type 2 diabetes that could be targeted to prevent or treat the disease. The research highlights a previously unrecognized molecular pathway that contributes to the malfunction of liver cells in obesity, leading to insulin resistance and diabetes.
	Drugs to block angiogenesis could provide new treatment for TB The body responds to tuberculosis infection by locking the bacterial offenders into tiny clusters of immune cells called granulomas, which are a hallmark of the disease. This containment strategy succeeds at first, but eventually the bacteria manage to break out of these intercellular jails and spread throughout the body.
	Team identifies new mechanism for misfolded proteins in heart disease A Jackson Laboratory research team has found that the misfolded proteins implicated in several cardiac diseases could be the result not of a mutated gene, but of mistranslations during the "editing" process of protein synthesis.
Scientists convert human skin cells into sensory neurons A team led by scientists from The Scripps Research Institute (TSRI) has found a simple method to convert human skin cells into the specialized neurons that detect pain, itch, touch and other bodily sensations. These neurons are also affected by spinal cord injury and involved in Friedreich's ataxia, a devastating and currently incurable neurodegenerative disease that largely strikes children.
	Babies remember nothing but a good time, study says Parents who spend their time playing with and talking to their five-month-old baby may wonder whether their child remembers any of it a day later.
	Muscle relaxant may be viable treatment for Wolfram syndrome—rare form of diabetes A commonly prescribed muscle relaxant may be an effective treatment for a rare but devastating form of diabetes, researchers at Washington University School of Medicine in St. Louis report.
Adult survivors of childhood eye cancer experience few cognitive or social setbacks Most long-term survivors of retinoblastoma, particularly those who had been diagnosed with tumors by their first birthdays, have normal cognitive function as adults, according to a St. Jude Children's Research Hospital study. The research, which appears in the current issue of the journal Cancer, found that the vast majority of survivors work full time, live independently and fulfill other milestones of adult life.
	Chilean moms growing support for medical marijuana Paulina Bobadilla was beyond desperate. The drugs no longer stopped her daughter's epileptic seizures and the little girl had become so numb to pain, she would tear off her own fingernails and leave her small fingers bleeding.
Scientists raise alarm that shortage of human islet cells will slow diabetes research Rohit Kulkarni, M.D., Ph.D., Senior Investigator in the Section on Islet Cell and Regenerative Biology at Joslin Diabetes Center and Associate Professor at Harvard Medical School, coauthored a paper that was published today in Diabetes, which voiced concerns about the increasing difficulty of access to high quality islet cells for diabetes research. Andrew Stewart, M.D., Director of the Diabetes, Obesity and Metabolism Institute at of Mount Sinai Hospital in New York, served as the other lead author.
	Possible cause discovered for failure of targeted liver cancer therapies The failure of experimental liver cancer therapies directed specifically against the EGFR protein is presumably the result of insufficiently specific patient selection. This is the conclusion that can be drawn from data that were obtained within the framework of a project carried out by an Austrian Science Fund FWF doctoral programme, and that have now been published in Nature Cell Biology. The data prove that the tumour-promoting effect of EGFR originates, not directly from its expression in the tumour cells, but rather from its presence in the surrounding cells (macrophages) of the immune system. This predicts that experimental anti-EGFR therapeutic agents will prove effective only in patients who exhibit EGFR in the immune cells. This expanded understanding of the occurrence of EGFR in macrophages now offers, however, potential new approaches for the treatment of liver cancer.
	High carriage rates of Giardia among children in a remote Indigenous community Recent research in a remote Indigenous community in the Northern Territory has found high carriage rates of the intestinal parasite Giardia among children. Giardia duodenalis is an enteric parasite that causes gastrointestinal disease (giardiasis) including symptoms of diarrhoea and vomiting, but can lead to malnutrition and wasting among children who are constantly infected.

	Rise in anti-psychotic scripts for kids is a serious worry News this week that as many as 100,000 prescriptions for anti-psychotics were written for Australian children in 2013 is cause for concern. Though the drugs may be appropriate in a small number of cases, their possibly irreversible side effects make them highly undesirable for use in children.
Research centre to tackle musculoskeletal disorders in the workplace A major new research centre to tackle the impact of musculoskeletal disorders on people's ability to work has been announced by two leading medical research bodies.
	Declining loneliness among American teenagers There has been a growing concern that modern society is increasingly lonely. In 2006, a New York Times article "The Lonely American Just Got a Bit Lonelier" highlighted research that shows a decline in social engagement—people are less likely to join clubs, have fewer close friends, and are less likely to perceive others as trustworthy. However, studies have also shown an increase in extraversion and self-esteem, which suggests loneliness is decreasing.
	More aging boomers, but fewer doctors to care for them By 2030, the last of the Baby Boomer generation will have turned 65 years old, putting the population of "senior boomers" in the United States at approximately 71 million. Currently, only about 7,000 certified geriatricians – physicians specializing in the care of older adults – are practicing in the US. That's about one geriatrician for every 10,000 of these expected seniors, assuming that the number of geriatricians remains stable. However, the number of new trainees in the field of geriatrics is going down.

	Football players found to have brain damage from mild 'unreported' concussions A new, enhanced MRI diagnostic approach was, for the first time, able to identify significant damage to the blood-brain barrier (BBB) of professional football players following "unreported" trauma or mild concussions. Published in the current issue of JAMA Neurology, this study could improve decision making on when an athlete should "return to play."
	Obese children burdened by more than weight High blood pressure and nonalcoholic fatty liver disease (NAFLD) are two emerging health problems related to the epidemic of childhood obesity. In a recent study, researchers at University of California, San Diego School of Medicine sought to determine the prevalence of high blood pressure in children with NAFLD, which places them at risk for premature cardiovascular disease.
Experience with family verbal conflict as a child can help in stressful situations as an adult The holiday season gives people the opportunity to reconnect with friends and family each year. Sometimes these interactions can be stressful, especially around the Thanksgiving table where a heated debate can occur. How come some people are better at handling these stressful interactions than others? A recent study published in the journal Human Communication Research by researchers at Rollins College and The Pennsylvania State University found that individuals who were exposed to intense verbal aggression as children are able to handle intense conflict later in life.
Starting treatment soon after HIV infection improves immune health, study finds HIV-1-infected U.S. military members and beneficiaries treated with antiretroviral therapy (ART) soon after infection were half as likely to develop AIDS and were more likely to reconstitute their immune-fighting CD4+ T-cells to normal levels, researchers reported Nov. 24 in JAMA Internal Medicine.
	Study finds most older adults qualify for statin therapy under new cholesterol guidelines Nearly all individuals in their late 60s and early 70s—including 100 percent of men—now qualify for and should consider starting a statin medication to reduce their risk of cardiovascular disease, under the recently released cholesterol guidelines from the American College of Cardiology (ACC) and the American Heart Association (AHA).
