Astronomy & Space news

	Cosmic first: European spacecraft lands on comet (WATCH LIVE) Landing with a bounce after traveling 4 billion miles, a European spacecraft made history Wednesday by successfully reaching the icy, dusty surface of a speeding comet—a cosmic first designed to answer big questions about the universe.
	Venturing into the upper atmosphere of Venus As the end of its eight-year adventure at Venus edges ever closer, ESA scientists have been taking a calculated risk with the Venus Express spacecraft in order to carry out unique observations of the planet's rarefied outer atmosphere. First results from this aerobraking campaign were reported today at the 2014 Division for Planetary Science meeting, in Tucson, Arizona.
	Astronomers thrilled by extreme storms on Uranus The normally bland face of Uranus has become increasingly stormy, with enormous cloud systems so bright that for the first time ever, amateur astronomers are able to see details in the planet's hazy blue-green atmosphere.
	Comet lander may not be securely anchored: ESA A European probe Wednesday made the first-ever landing on a comet in a quest to explore the origins of the Solar System, but there were concerns over whether it was fastened securely enough to carry out its mission.
	All systems go for historic comet landing (WATCH LIVE) The European Space Agency (ESA) ordered a probe to attempt Wednesday the first landing on a comet and investigate one of the great mysteries of the Solar System.
	NASA hails comet landing as 'breakthrough moment' NASA on Wednesday hailed the first-ever landing of a spacecraft on a comet as a "breakthrough moment" in the history of space exploration.
	Rosetta begins descending to comet 67P (WATCH LIVE) Hundreds of millions of miles from Earth, a speeding European spacecraft released a lander toward the icy, dusty surface of a comet on Wednesday, setting off a seven-hour countdown to an audacious attempt to answer some of the biggest questions about the origin of the universe.
Planetary scientist explains the significance of the historic Rosetta satellite mission After 10 years and four billion miles NASA's Rosetta satellite is poised make space science history tomorrow when it launches its Philae lander onto the surface of the ancient comet, 67P/Churyumov-Gerasimenko.
	Image: Rosetta solar wing This is one of Rosetta's two massive solar wings, keeping ESA's comet-chaser powered out in the cold depths of space, currently some 448 million km from the Sun.
	Explainer: Why the Rosetta comet mission is such a big deal The first attempted landing on the surface of a comet is a huge landmark in the history of space exploration that will not only uncover further details about comets but could unlock further clues about the origins of our solar system and the development of life on Earth.
	From doomsday to fact: Science lifts veil on comets For millennia, the sight of a comet filled humans with awe or dread.
	Giant sunspot returns – and it's bigger and badder than ever The largest sunspot seen in 24 years is rotating back to face the Earth, and it looks to have grown even bigger.
	Guide to the 2014 Leonid meteors If there's one meteor shower that has the potential to bring on a storm of epic proportions, it's the Leonids. Peaking once every 33 years, these fast movers hail from the Comet 55P Temple-Tuttle, and radiate from the Sickle, or backwards "question mark" asterism in the constellation Leo. And although 2014 is an "off year" in terms of storm prospects, it's always worth taking heed these chilly November mornings as we await the lion's roar once again.
	NASA sun probe silent now for six weeks No one knows exactly why a NASA solar probe stopped talking to Earth six weeks ago, but it's possible the spacecraft is out of power and is drifting without a way of calling for help, the agency said in an update.
	Relief as signal arrives from comet lander Europe's Rosetta spacecraft made contact with its robot craft Philae soon after the lander embarked Wednesday on a solo, seven-hour descent to a comet, ground controllers said. (WATCH LIVE)

	Five questions about the historic comet landing The European Space Agency has achieved a historic first—landing a washing machine-sized spacecraft on a comet speeding through our solar system at 41,000 mph (66,000 kph). Here are answers to five questions about the space mission:
European probe lands on comet, fails to anchor (Update) Europe made history Wednesday by placing the first-ever lander on a comet—but the robot failed to anchor itself properly, raising concerns at ground control.
	Spaceship pilot unaware co-pilot unlocked brake The pilot of the Virgin Galactic spaceship that tore apart over the Mojave Desert didn't know his co-pilot had prematurely unlocked its brakes, despite protocol requiring the co-pilot to announce the step.
	NASA's new capsule at launch pad for test flight NASA's new Orion spacecraft is now at the launch pad for next month's test flight.
	Rosetta's comet sings strange, seductive song Scientists can't figure exactly why yet, but Comet 67P/Churyumov-Gerasimenko has been singing since at least August. Listen to the video – what do you think? I hear a patter that sounds like frogs, purring and ping-pong balls. The song is being sung at a frequency of 40-50 millihertz, much lower than the 20 hertz – 20 kilohertz range of human hearing. Rosetta's magnetometer experiment first clearly picked up the sounds in August, when the spacecraft drew to within 62 miles (100 km) of the comet. To make them audible Rosetta scientists increased their pitch 10,000 times.

Medicine & Health news

	'Smart' drugs won't make smart people smarter It is claimed one in five students have taken the 'smart' drug Modafinil to boost their ability to study and improve their chances of exam success. But new research into the effects of Modafinil has shown that healthy students could find their performance impaired by the drug.
	Scientists discover new properties of microbes that cause common eye infection Scientists from Massachusetts Eye and Ear/Harvard Medical School Department of Ophthalmology have used the power of new genomic technology to discover that microbes that commonly infect the eye have special, previously unknown properties. These properties are predicted to allow the bacterium—Streptococcus pneumoniae—to specifically stick to the surface of the eye, grow, and cause damage and inflammation.
	Facial structure predicts goals, fouls among World Cup soccer players The structure of a soccer player's face can predict his performance on the field—including his likelihood of scoring goals, making assists and committing fouls—according to a study led by a researcher at the University of Colorado Boulder.
Molecular profiling of Ketamine's rapid antidepressant effect One third of the patients with major depressive disorder suffer from treatment resistance and do not respond to commonly used antidepressants. Ketamine, a drug that works through a different mechanism, improves depressive symptoms within hours and is particularly effective in treatment-resistant patients. Scientists at the Max Planck Institute of Psychiatry in Munich have for the first time identified metabolite alterations, affected pathways and biomarker candidates for the Ketamine treatment response in mice. An improved understanding of the molecular events causing the rapid antidepressant effect of Ketamine will allow the development of alternative drugs with a similar mode of action but fewer side effects.
	Research links tobacco smoke and roadway air pollution with childhood obesity New research from Keck Medicine of the University of Southern California (USC) bolsters evidence that exposure to tobacco smoke and near-roadway air pollution contribute to the development of obesity.
	Bilingual brains better equipped to process information Speaking more than one language is good for the brain, according to new research that indicates bilingual speakers process information more efficiently and more easily than those who know a single language.
	Discovery opens up possibility of slowing cancer spread A trawl through a library of more than 50,000 'small molecules' has identified a potential candidate to inhibit the spread of cancer cells throughout the body. Reported today in the journal Nature Communications, the molecule targets a mechanism of tumour development that had previously been considered 'undruggable'– in other words, extremely difficult, if not impossible, to target with a drug – and could open the door to further promising new candidates.
	Scientists unveil new targets, test to develop treatments for memory disorder In a pair of related studies, scientists from the Florida campus of The Scripps Research Institute (TSRI) have identified a number of new therapeutic targets for memory disorders and have developed a new screening test to uncover compounds that may one day work against those disorders.
Best supporting actors in your ears?

This innovative approach reduced self-criticism and increased self-compassion and feelings of contentment in naturally self-critical individuals. The scientists behind the MRC-funded study say it could be applied to treat a range of clinical conditions including depression.
	Semen directly impairs effectiveness of microbicides that target HIV In the fight against HIV, microbicides—chemical compounds that can be applied topically to the female genital tract to protect against sexually transmitted infections—have been touted as an effective alternative to condoms. However, while these compounds are successful at preventing transmission of the virus in a petri dish, clinical trials using microbicides have largely failed. A new study from the Gladstone Institutes and the University of Ulm now reveals that this discrepancy may be due to the primary mode of transportation of the virus during sexual transmission, semen.
	World's oldest people share no genetic secrets, study finds Think the reason some people live beyond the age of 100 is because of their genes? Think again.
	Learning languages is a workout for brains, both young and old Learning a new language changes your brain network both structurally and functionally, according to Penn State researchers. "Learning and practicing something, for instance a second language, strengthens the brain," said Ping Li, professor of psychology, linguistics and information sciences and technology. "Like physical exercise, the more you use specific areas of your brain, the more it grows and gets stronger."
	Errors in single gene may protect against heart disease Rare mutations that shut down a single gene are linked to lower cholesterol levels and a 50 percent reduction in the risk of heart attack, according to new research from Washington University School of Medicine in St. Louis, the Broad Institute at Massachusetts Institute of Technology and Harvard, and other institutions.
	Brain protein influences how the brain manages stress; suggests new model of depression The brain's ability to effectively deal with stress or to lack that ability and be more susceptible to depression, depends on a single protein type in each person's brain, according to a study conducted at the Icahn School of Medicine at Mount Sinai and published November 12 in the journal Nature.
	The backwards brain? Study shows how brain maps develop to help us perceive the world Driving to work becomes routine—but could you drive the entire way in reverse gear? Humans, like many animals, are accustomed to seeing objects pass behind us as we go forward. Moving backwards feels unnatural.
	Humans' big brains might be due in part to newly identified protein A protein that may partly explain why human brains are larger than those of other animals has been identified by scientists from two stem-cell labs at UC San Francisco, in research published in the November 13, 2014 issue of Nature.

Oral cancer-causing HPV may spread through oral and genital routes Oral human papillomavirus (HPV) infections were more common among men who had female partners with oral and/or genital HPV infection, suggesting that the transmission of HPV occurs via oral-oral and oral-genital routes, according to a McGill University study published in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research.
Scoring system masks variation between GPs' communication skills A large-scale study has revealed that the system of aggregating practice scores on GPs' communication skills may mask variation between individual doctors in lower-scoring centres.
Experts urge US to change organ donation policies A group of more than 300 prominent doctors, religious leaders and ethicists on Wednesday urged President Barack Obama to change the current system for organ donation, saying too few people get life-saving transplants.
Psychotropic drug prescriptions: Therapeutic advances or fads? Why are psychotropic drugs such as antidepressants, psychostimulants, anxiolytics, and antipsychotics are increasingly prescribed in North America? Drawing a parallel between the dilemmas facing medicine in the nineteenth century and those that currently exist in the field of mental health, the sociologist and historian Johanne Collin, a professor at the Université de Montréal's Faculty of Pharmacy, believes this increase in prescriptions is partly explained by the therapeutic reasoning of physicians.
	Mothers nurture emotions in girls over boys, new study finds A new study published today in The British Journal of Developmental Psychology has found that conversations mothers have with their daughters tend to contain more emotional words and content, than the conversations they have with their sons.
Researchers studying blood test that could reduce antibiotic use A new blood biomarker test that indicates whether bacteria is the cause of a patient's lung infection is now being studied at UPMC Presbyterian, launching a national multicenter trial. The information could help doctors decide when to prescribe antibiotics and possibly reduce overuse of the drugs, which can lead to antibiotic-resistant strains of bacteria.
HPV vaccine uptake among girls is lowest in states with highest rates of cervical cancer The proportion of adolescent girls receiving human papillomavirus (HPV) vaccines was much lower in states with higher rates of cervical cancer incidence and mortality, according to data presented at the American Association for Cancer Research (AACR) conference on The Science of Cancer Health Disparities in Racial/Ethnic Minorities and the Medically Underserved, held Nov. 9–12.
	Implementing ACA-mandated health risk assessments will stretch primary care providers beyond capacity Primary care practices are willing to implement behavioral and mental health assessments required by the Affordable Care Act, but lack the resources to do so effectively, and if they implement the assessments, the high number of health risks identified will likely stretch many practices beyond treatment capacity, according to a Virginia Commonwealth University-led study that produced two articles published this month in the Annals of Family Medicine.
	Researchers help China to better predict dengue fever outbreaks Queensland University of Technology (QUT) researchers have found the habit of Googling for an online diagnosis before visiting the doctor can be a powerful predictor of infectious diseases outbreaks.

Innovative approach to treating pancreatic cancer combines chemo- and immuno-therapy VCU Massey Cancer Center and VCU Institute of Molecular Medicine (VIMM) researchers discovered a unique approach to treating pancreatic cancer that may be potentially safe and effective. The treatment method involves immunochemotherapy - a combination of chemotherapy and immunotherapy, which uses the patient's own immune system to help fight against disease. This pre-clinical study, led by Paul B. Fisher, M.Ph., Ph.D., and Luni Emdad, M.B.B.S., Ph.D., found that the delivery of [pIC]PEI - a combination of the already-established immune-modulating molecule, polyinosine-polycytidylic acid (pIC), with delivery molecule polyethlenimine (PEI), a polymer often used in detergents, adhesives and cosmetics - inside pancreatic cancer cells triggers cancer cell death without harming normal pancreatic cells.

Single-dose, needle-free Ebola vaccine provides long-term protection in macaques Scientists have demonstrated for the first time that a single-dose, needleless Ebola vaccine given to primates through their noses and lungs protected them against infection for at least 21 weeks. A vaccine that doesn't require an injection could help prevent passing along infections through unintentional pricks. They report the results of their study on macaques in the ACS journal Molecular Pharmaceutics.
How does the brain develop in individuals with autism? Geneticists at Heidelberg University Hospital's Department of Molecular Human Genetics have used a new mouse model to demonstrate the way a certain genetic mutation is linked to a type of autism in humans and affects brain development and behavior. In the brain of genetically altered mice, the protein FOXP1 is not synthesized, which is also the case for individuals with a certain form of autism. Consequently, after birth the brain structures degenerate that play a key role in perception. The mice also exhibited abnormal behavior that is typical of autism. The new mouse model now allows the molecular mechanisms in which FOXP1 plays a role to be explained and the associated changes in the brain to be better understood.
	Moderate consumption of sugary drinks has little impact on adolescents' metabolic health Sugar-sweetened beverages are the largest source of added sugar in the diets of adolescents in the United States, and young adults ages 15-20 consume more of these drinks than any other age group, according to the Centers for Disease Control and Prevention. Adolescent obesity rates, which have quadrupled over the past thirty years, led to widespread scrutiny of added dietary sugars, especially those found in carbonated beverages. Now, MU researchers have found that short-term, moderate consumption of high-fructose and high-glucose beverages has little impact on the metabolic health of weight-stable, physically active adolescents.
	Team identifies genetic variant linked to better memory performance People with a newly identified genetic variant perform better on certain types of memory tests, a discovery that may point the way to new treatments for the memory impairments caused by Alzheimer's disease or other age-associated conditions.
Single molecular switch may contribute to major aging-related diseases A study led by Massachusetts General Hospital (MGH) investigators has identified what appears to be a molecular switch controlling inflammatory processes involved in conditions ranging from muscle atrophy to Alzheimer's disease. In their report published in Science Signaling, the research team found that the action of the signaling molecule nitric oxide on the regulatory protein SIRT1 is required for the induction of inflammation and cell death in cellular and animal models of several aging-related disorders.
Not all elderly Americans will surf to health Providing health information on the internet may not be the "cure all" that it is hoped to be. It could sideline especially those Americans older than 65 years old who are not well versed in understanding health matters, and who do not use the web regularly. So says Helen Levy of the University of Michigan in the US, who led the first-ever study to show that elderly people's knowledge of health matters, so-called health literacy, also predicts how and if they use the internet. The findings appear in the Journal of General Internal Medicine.
	Rapid Heme Panel speeds treatment decisions for blood cancer patients For patients with aggressive types of leukemia and other blood cancers, quickly identifying and starting the right treatment can make all the difference.
Predicting US Army suicides after hospital discharge It has long been known that patients recently discharged from psychiatric hospitalizations have a significantly elevated suicide risk. However, the rarity of suicide even in this high-risk segment of the population makes it impractical to justify providing intensive post-hospital suicide prevention programs to all recently discharged patients. Targeted programs for patients at especially high suicide risk would be more feasible, but it is difficult for clinicians to predict with good accuracy which patients are at high risk for suicide.
Vitamin B may not reduce risk of memory loss, study says Taking vitamin B12 and folic acid supplements may not reduce the risk of memory and thinking problems after all, according to a new study published in the November 12, 2014, online issue of Neurology, the medical journal of the American Academy of Neurology. The study is one of the largest to date to test long-term use of supplements and thinking and memory skills.

Furin – the answer to the Ebola crises? With an estimated fatality rate of 52%, the need to discover a cure for Ebola has never been more urgent. New research published in Journal of Biomolecular Structure and Dynamics this month suggests that scientists currently investigating potential cures for the Ebola virus should focus more attention on the protein furin.
New survey of US workers reveals two in five survey participants missed work due to depression Nearly a quarter (23 percent) of U.S. respondents indicated they have been diagnosed with depression in their lifetime and two in five (nearly 40 percent) of those patients reported taking time off of work - an average of 10 days a year - as a result of their diagnosis. These findings are just a few of the key outcomes stemming from The Impact of Depression at Work Audit (IDeA), evaluating the societal and economic burden of depression in the workplace. Employers Health, an Ohio-based employer coalition, announced results for the U.S. survey at the National Business Coalition on Health annual meeting in Washington, D.C. on November 12.
