Astronomy & Space news

	What does the next generation telescope need to detect life? Almost 2,000 extrasolar planets have been discovered to date and this number is constantly increasing. Yet, we still know little about these alien worlds, especially their atmospheres. The atmospheres of terrestrial exoplanets could betray the presence of life on the planet, sparking NASA's interest in acquiring the spectra that appears as starlight shines through these planetary atmospheres.
	'Eau de comet' is a bit of a stinker Rotten eggs, horse pee, alcohol and bitter almonds: this is the bouquet of odours you would smell if a comet in deep space could be brought back to Earth, European scientists said on Thursday.
	Earth hit by double asteroids 458 million years ago Some 458 million years ago, Earth was whacked in a double asteroid strike, leaving craters visible in Sweden today, space scientists reported on Thursday.
	Lucky star escapes black hole with minor damage Astronomers have gotten the closest look yet at what happens when a black hole takes a bite out of a star—and the star lives to tell the tale.
	OSIRIS images of Rosetta's comet show spectacular streams of dust emitted into space Rosetta's comet 67P/Churyumov-Gerasimenko is beginning to show a clearly visible increase in activity. While in the past months most of the dust emitted from the body's surface seemed to originate from the neck region which connects the two lobes, images obtained by Rosetta's scientific imaging system OSIRIS now show jets of dust along almost the whole extent of the comet.
	Close encounters: Comet siding spring seen next to mars (Phys.org) —This composite NASA Hubble Space Telescope Image captures the positions of comet Siding Spring and Mars in a never-before-seen close passage of a comet by the Red Planet, which happened at 2:28 p.m. EDT October 19, 2014. The comet passed by Mars at approximately 87,000 miles (about one-third of the distance between Earth and the Moon). At that time, the comet and Mars were approximately 149 million miles from Earth.
	NASA taps Livermore photon scientists for heat-shield research Researchers in Lawrence Livermore National Laboratory's NIF & Photon Science Directorate are working with NASA Ames Research Center at Moffet Field, California on the development of technology to simulate re-entry effects on the heat shield for the Orion spacecraft, NASA's next crewed spaceship. Orion is designed to carry astronauts beyond low Earth orbit to deep-space destinations such as an asteroid and, eventually, Mars.
	NASA ultra-black nano-coating to be applied to 3-D new solar coronagraph An emerging super-black nanotechnology that is to be tested for the first time this fall on the International Space Station will be applied to a complex, 3-D component critical for suppressing stray light in a new, smaller, less-expensive solar coronagraph designed to ultimately fly on the orbiting outpost or as a hosted payload on a commercial satellite.
	The great world wide star count How many stars can you see at night? Right now people all over the world are being asked to go out and count them!
	The formation and development of desert dunes on Titan Combining climate models and observations of the surface of Titan from the Cassini probe, a team from the AIM Astrophysics Laboratory (CNRS / CEA / Paris Diderot University) , in collaboration with researchers at the Paris Earth Physics Institute (IPGP / CNRS / Paris Diderot University) and the Matter and Complex Systems Laboratory - MSC (CNRS / Paris Diderot University), have proposed a new formation and growth mechanism for the dunes on the surface of the moon. This growth mechanism, also seen in some terrestrial deserts and on the planet Mars, appears to be the dominant mechanism in the deserts of Titan, explaining not only the shape of the dunes, but also their orientation and direction of growth, together with their confinement to the tropical belt around the moon. The results of this study have been published in Geophysical Research Letters.
	Assembly complete for NASA's maiden Orion spacecraft launching in December 2014 Technicians at the Kennedy Space Center have completed the final major assembly work on NASA's maiden Orion crew module slated to launch on its first unmanned orbital test flight this December, dubbed Exploration Flight Test-1 (EFT-1)
	Beastly sunspot amazes, heightens eclipse excitement That's one big, black blemish on the Sun today! Rarely have we been witness to such an enormous sunspot. Lifting the #14 welder's glass to my eyes this morning I about jumped back and bumped into the garage.
The search for habitable worlds, from sub-Neptunes to super-Earths During a live Google Hangout, three astrophysicists—Zachory Berta-Thompson, Bruce Macintosh and Marie-Eve Naud—discussed the huge variety of planets discovered so far, how close we are to being able to see other Earth-like planets, and all that remains unknown.
	Researchers highlight acousto-optic tunable filter technology for balloon-borne platforms Narrowband or hyperspectral imaging is a valuable technique used in planetary science for characterizing surfaces and surrounding environments. For example, it can be used to spatially map molecular species of interest on the surface of a solid or icy body, or to sound to different depths in a giant planet atmosphere. However, conducting narrowband or hyperspectral imaging of solar system targets from a balloon-borne platform presents several technical challenges, including mechanical failures and power requirements. These risks can be mitigated with the use of an electronically tunable filter such as an acousto-optic tunable filter (AOTF).

Medicine & Health news

	Researchers find novel way body defends against harmful bacteria Bacterial infections can cause major problems for people undergoing treatment for cancer and other diseases. The concern is especially acute during hospitalization, when patients often have weakened immune function.
	Stopping anti-CCL2 breast cancer treatment aggravates the disease Mohamed Bentires-Alj and his team at the Friedrich Miescher Institute for Biomedical Research (FMI) together with scientists from the Novartis Institutes for BioMedical Research (NIBR) show in a study published today in Nature that a promising therapeutic approach for metastatic breast cancer elicits deleterious effects after cessation of the treatment. Stopping CCL2 inhibition paradoxically increases metastasis formation and leads to premature death thus thwarting the initially beneficial effects of the treatment. This has implications for the design of therapies targeting these processes and indicates that therapeutic approaches to inactivate the chemokine CCL2 should be administered with extreme caution.
	Thyroid cancer genome analysis finds markers of aggressive tumors A new comprehensive analysis of thyroid cancer from The Cancer Genome Atlas Research Network has identified markers of aggressive tumors, which could allow for better targeting of appropriate treatments to individual patients.
	People with type 2 diabetes are physically less able to recover from stress (Medical Xpress)—People with type 2 diabetes are physically less able to recover from stress, finds a study by scientists at UCL and the University of Zurich, funded by the British Heart Foundation.
	Flu viruses disguised as waste: Crafty manipulator deceives cellular waste disposal system Disguising itself as waste, the shell of the flu virus is torn apart by the cell's own disposal system, thereby releasing viral genetic information. For the first time, a research team headed by researchers at ETH Zurich has now managed to show the exact process.
	Music therapy reduces depression in children and adolescents Researchers at Queen's University Belfast have discovered that music therapy reduces depression in children and adolescents with behavioural and emotional problems.
New test could identify infants with rare insulin disease A rare form of a devastating disease which causes low blood sugar levels in babies and infants may now be recognised earlier thanks to a new test developed by researchers from The University of Manchester.
Two days later: Adolescents' conflicts with family spill over to school, vice versa Family conflict and problems at school tend to occur together on the same day. A new study has found that these problems spill over in both directions for up to two days after. The study found that teens with more pronounced mental health symptoms, anxiety and depression, for example, are at risk for intensified spillover. The study followed over a hundred 13 to 17 year olds and their parents over a 14-day period.
'Breath test' shows promise for diagnosing fungal pneumonia Many different microbes can cause pneumonia, and treatment may be delayed or off target if doctors cannot tell which bug is the culprit. A novel approach—analyzing a patient's breath for key chemical compounds made by the infecting microbe—may help detect invasive aspergillosis, a fungal infection that is a leading cause of mortality in patients with compromised immune systems, according to a proof-of-concept study now online in Clinical Infectious Diseases.
Children in high-quality early childhood education are buffered from changes in family income While losses in family income predict increases in behavior problems for many children, attending high-quality early childhood education and care centers offers some protection against families' economic declines, according to a new study out of Norway. In Norway, publicly subsidized high-quality early childhood education and care is available to all children, from low-income to affluent, starting at age 1. The study found that children who don't take part in such programs have more early behavior problems when their families' income drops.
Teens whose parents exert more psychological control have trouble with closeness, independence For teenagers, learning to establish a healthy degree of autonomy and closeness in relationships (rather than easily giving in to peer pressure) is an important task. A new longitudinal study has found one reason adolescents struggle with balancing autonomy and closeness in relationships: parents' psychological control. Teens whose parents exerted more psychological control over them when they were 13 had more problems establishing friendships and romantic relationships that balanced closeness and independence, both in adolescence and into early adulthood.

	New insight on why people with Down syndrome invariably develop Alzheimer's disease A new study by researchers at Sanford-Burnham Medical Research Institute reveals the process that leads to changes in the brains of individuals with Down syndrome—the same changes that cause dementia in Alzheimer's patients. The findings, published in Cell Reports, have important implications for the development of treatments that can prevent damage in neuronal connectivity and brain function in Down syndrome and other neurodevelopmental and neurodegenerative conditions, including Alzheimer's disease.
'Long tail' thinking can help eliminate health disparities "Long tail" thinking in public health might yield greater progress in eliminating health disparities, according to a new study from the Brown School at Washington University in St. Louis.
	Doctors must examine own weight bias before treating patients, researcher says In the war on obesity, the medical profession is needed on the front lines. Yet there is mounting concern that some practitioners harbor a negative weight bias.
Gene that once aided survival in the Arctic found to have negative impact on health today In individuals living in the Arctic, researchers have discovered a genetic variant that arose thousands of years ago and most likely provided an evolutionary advantage for processing high-fat diets or for surviving in a cold environment; however, the variant also seems to increase the risk of hypoglycemia, or low blood sugar, and infant mortality in today's northern populations. The findings, published online October 23 in Cell Press's American Journal of Human Genetics, provide an example of how an initially beneficial genetic change could be detrimental to future generations.
	New study identifies potential targets for personalized cancer vaccines (Medical Xpress)—A team of University of Notre Dame scientists, in collaboration with researchers at the University of Connecticut, have announced the results of a new study on identifying potential targets for personalized cancer vaccines.

Traumatic stress may affect DNA, but psychotherapy may heal it A new study published in the current issue of Psychotherapy and Psychosomatics for the first time demonstrates that traumatic stress may induce DNA breakage, but psychotherapy may heal it. Previous research reveals an association between traumatic stress and an increased risk for numerous diseases, including cancer. At the molecular level, stress may increase carcinogenesis via increased DNA damage and impaired DNA repair mechanisms. The authors assessed DNA breakage in peripheral blood mononuclear cells from individuals with post-traumatic stress disorder (PTSD) and measured the cellular capacity to repair single-strand breaks after exposure to ionizing X-radiation. They also investigated the effect of psychotherapy on both DNA breakage and DNA repair.
Changing lifestyle may improve cognitive function in the elderly A randomized controlled trial published in the current issue of Psychotherapy and Psychosomatics indicates that modifications in lifestyle may improve cognitive function in the elderly. Since a healthy lifestyle may protect against cognitive decline, the authors examined outcomes in elderly individuals after 18 months of a five-group intervention program consisting of various modalities: physical activity, antismoking, social activity, cognitive activity, alcohol drinking in moderation, and leaning about body mass and a healthy diet.
	New window of opportunity to prevent cardiovascular and cerebrovascular diseases Future prevention and treatment strategies for vascular diseases may lie in the evaluation of early brain imaging tests long before heart attacks or strokes occur, according to a systematic review conducted by a team of cardiologists, neuroscientists, and psychiatrists from Icahn School of Medicine at Mount Sinai and published in the October issue of JACC Cardiovascular Imaging.

The study, titled "Sleep Onset and Night Waking Insomnias in Preschoolers with Psychiatric Disorders," is now published online in the journal Child Psychiatry & Human Development.
A gut bacterium that attacks dengue and malaria pathogens and their mosquito vectors Just like those of humans, insect guts are full of microbes, and the microbiota can influence the insect's ability to transmit diseases. A study published on October 23rd in PLOS Pathogens reports that a bacterium isolated from the gut of an Aedes mosquito can reduce infection of mosquitoes by malaria parasites and dengue virus. The bacterium can also directly inhibit these pathogens in the test tube, and shorten the life span of the mosquitoes that transmit both diseases.
Mother's gestational diabetes linked to daughters being overweight later Women who developed gestational diabetes and were overweight before pregnancy were at a higher risk of having daughters who were obese later in childhood, according to new research published today in Diabetes Care.
Genetic causes underlying the disqualification of two elite American Standardbred pacers A DNA mutation that can lead to horses being genetically male, but female in appearance, may explain at least two cases of controversial sexual identity, according to research led by professors from the Texas A&M College of Veterinary Medicine & Biomedical Sciences (CVM) and published in PLOS Genetics.

The study will appear in the November 6 edition of the scientific journal Cell Reports.
Cancer exosome 'micro factories' aid in cancer progression Exosomes, tiny, virus-sized particles released by cancer cells, can bioengineer micro-RNA (miRNA) molecules resulting in tumor growth. They do so with the help of proteins, such as one named Dicer. New research from The University of Texas MD Anderson Cancer Center suggests Dicer may also serve as a biomarker for breast cancer and possibly open up new avenues for diagnosis and treatment. Results from the investigation were published in today's issue of Cancer Cell.
	Study finds significant increase in type 1 diabetes rates among non-Hispanic white youth The rate of non-Hispanic white youth diagnosed with type 1 diabetes increased significantly from 2002 to 2009 in all but the youngest age group of children, according to a new study published today in the journal Diabetes.

New drug naming system unveiled at ECNP in Berlin What's in a name? Doctors have found that the name of the drug you are prescribed significantly influences how the patient sees the treatment. Now in a significant shift, the world's major psychiatry organisations are proposing to completely change the terminology of the drugs used in mental disorders shifting it from symptom based (e.g. antidepressant, antipsychotic etc.) to pharmacologically based (e.g. focusing on pharmacological target (serotonin, dopamine etc.) and the relevant mode of action). This will mean that patient will no longer have the confusion of being prescribed a drug for what appears to be an unrelated condition, but also means that drug names will be more understandable to doctors.
England's NHS appeals for more government funds Leaders of England's state-funded National Health Service (NHS) warned on Thursday that billions of pounds in extra funds were needed to maintain patient care, laying down the gauntlet to politicians ahead of May's general election.
Initiative to emphasize concussions are treatable At a time when the national concussion conversation instills fear and uncertainty among parents and athletes at all levels, the UPMC Sports Medicine Concussion Program is working to change the current discussion where two powerful messages are lost: Concussions can be treated, and there are evidence-based therapies that result in full recoveries every day.

Added benefit of vedolizumab is not proven Vedolizumab (trade name Entyvio) has been approved since May 2014 for patients with moderately to severely active Crohn disease or ulcerative colitis. In an early benefit assessment pursuant to the Act on the Reform of the Market for Medicinal Products (AMNOG), the German Institute for Quality and Efficiency in Health Care (IQWiG) examined whether the drug offers an added benefit over the appropriate comparator therapy in these patient groups. According to the findings, such an added benefit is not proven because the dossier contained no suitable data for any of the two therapeutic indications.
Poland bans junk food in schools Poland on Thursday banned junk food in schools from January next year to trim rising rates of childhood obesity.
	The Homeless World Cup isn't immune to Ebola fear-mongering Convenience stores in Santiago, Chile still stock Coca-Cola bottles adorned with 2014 FIFA World Cup Brazil branding. It's a small reminder of the ubiquity and overhang of the world's largest football event, which played out under some controversy on the eastern side of the continent three months ago.
	Country kids benefit from new burns education program Children in rural Western Australia are the main beneficiaries of a project delivering burns education to clinicians in remote areas.
'Watch' cites concern about flexible reamer breakage during anatomic ACL reconstruction JBJS Case Connector, an online case journal published by the Journal of Bone and Joint Surgery, has issued a "Watch" regarding concerns over flexible reamer breakage during anatomic single-bundle ACL reconstruction. Flexible reamers help surgeons achieve optimal femoral-tunnel parameters, but they are prone to breakage in certain situations, as the "Watch" article explains.
Useful markers to predict response to chemotherapy in patients with liver cancer A study led by the researcher at the Institute of Biomedical Research (IDIBELL), Isabel Fabregat, could serve to select patients with hepatocellular carcinoma unresponsive to most frequently used drug in liver cancer: sorafenib. The study, published in the International Journal of Cancer describes how tumor cells that have a less differentiated phenotype (mesenchymal) and expresses CD44, do not respond to Sorafenib action.
Paperwork consumes one-sixth of US physicians' time and erodes morale, study finds The average U.S. doctor spends 16.6 percent of his or her working hours on non-patient-related paperwork, time that might otherwise be spent caring for patients. And the more time doctors spend on such bureaucratic tasks, the unhappier they are about having chosen medicine as a career.
	New, faster therapeutic hypothermia techniques Rapid lowering of body temperature following an acute myocardial infarction (MI) can be an effective therapeutic strategy to minimize damage to the heart muscle caused by the loss and restoration of blood flow to the heart. While hypothermia shows clinical promise, current methods to cool the heart are insufficient. Faster, more effective techniques are needed to realize the full cardioprotective potential of this emerging intervention, as described in an article in Therapeutic Hypothermia and Temperature Management.

Anaplastic lymphoma kinase immunohistochemistry testing comparable to fluorescence in situ hybridization testing Sixteen institutions across Europe collaborated together to show for the first time that a semi-quantitative anaplastic lymphoma kinase (ALK) protein expression test, immunohistochemistry (IHC), is reliable amongst several laboratories and reviewers when test methodology and result interpretation are strictly standardized and the scoring pathologists are appropriately trained on the test.
An over-the-scope clipping device for endoscopic management of gastrointestinal defects is safe and effective An international multicenter study reports that over-the-scope clip (OTSC) placement is a safe and effective therapy for the closure of gastrointestinal (GI) defects, which includes anastomotic leaks, fistulae and perforations. Clinical success was best achieved in patients undergoing closure of perforations or leaks when OTSC placement was used for primary or rescue therapy. The overall clinical success for the closure of perforations and leaks ranged between 90 percent and 73 percent; however, successful closure of fistulae was achieved in less than half of the patients. The type of defect (i.e. perforation or leak) is the best predictor of successful long-term closure. The study appears in the October issue of GIE: Gastrointestinal Endoscopy, the monthly peer-reviewed scientific journal of the American Society for Gastrointestinal Endoscopy (ASGE).
