Astronomy & Space news

	Magnetic fields frozen into meteorite grains tell a shocking tale of solar system birth The most accurate laboratory measurements yet made of magnetic fields trapped in grains within a primitive meteorite are providing important clues to how the early solar system evolved. The measurements point to shock waves traveling through the cloud of dusty gas around the newborn Sun as a major factor in solar system formation.
	X-ray telescopes find black hole may be a neutrino factory (Phys.org) —The giant black hole at the center of the Milky Way may be producing mysterious particles called neutrinos. If confirmed, this would be the first time that scientists have traced neutrinos back to a black hole.
	Scientists hope for data after historic but dodgy comet landing European scientists were hoping for a stream of data Thursday after a robot lab made the first-ever landing on a comet, a key step in a marathon mission to probe the mysteries of space.
	Space agency releases first picture from comet The European Space Agency on Thursday published the first image taken from the surface of a comet, and said that its Philae lander is still "stable" despite a failure to latch on properly to the rocky terrain.
	Comet lander ends up in cliff shadow (Update) A shadow was cast—literally—across Europe's historic mission to land on and explore a comet. Scientists said Thursday the landing craft not only bounced twice, it also came to rest next to a cliff that's blocking sunlight from its solar panels.
	Mars, too, has macroweather Weather, which changes day-to-day due to constant fluctuations in the atmosphere, and climate, which varies over decades, are familiar. More recently, a third regime, called "macroweather," has been used to describe the relatively stable regime between weather and climate.
	The answer is blowing in the intergalactic wind Astronomers from the University of Toronto and the University of Arizona have provided the first direct evidence that an intergalactic "wind" is stripping galaxies of star-forming gas as they fall into clusters of galaxies. The observations help explain why galaxies found in clusters are known to have relatively little gas and less star formation when compared to non-cluster or "field" galaxies.
	Research reveals the real cause of death for some starburst galaxies Like hedonistic rock stars that live by the "better to burn out than to fade away" credo, certain galaxies flame out in a blaze of glory. Astronomers have struggled to grasp why these young "starburst" galaxies—ones that are very rapidly forming new stars from cold molecular hydrogen gas up to 100 times faster than our own Milky Way—would shut down their prodigious star formation to join a category scientists call "red and dead."
	New Horizons set to wake up for Pluto encounter (Phys.org) —NASA's New Horizons spacecraft comes out of hibernation for the last time on Dec. 6. Between now and then, while the Pluto-bound probe enjoys three more weeks of electronic slumber, work on Earth is well under way to prepare the spacecraft for a six-month encounter with the dwarf planet that begins in January.
	Despite landing fumble, comet probe working well (Update) Europe's comet probe Philae was "working well" despite a rough-and-tumble touchdown that left it partly shadowed from battery-boosting sunlight, ground controllers said Thursday.
	ICON cleared for next development phase NASA has officially confirmed the Ionospheric Connection Explorer, or ICON, mission, clearing it to move forward into the development phase. ICON will explore a swath of Earth's atmosphere where weather close to the ground impacts the dynamic space environment above in unexpected ways.
	How Rosetta made an epic journey through space and overcame incredible challenges Imagine launching a robotic spacecraft on a ten-year mission to land on a comet, 600 million kilometres from Earth, knowing that you will not be able to make any physical repairs to the craft during the journey. This daunting engineering challenge has been the ultimate goal of the European Space Agency's (ESA) Rosetta mission.
	Comet photos awaken wonder at space exploration It took a set of retro-looking images to reawaken the world's sense of wonder about space exploration.
	GOES-S satellite EXIS instrument passes final review One of the instruments that will fly aboard NOAA's GOES-S satellite has completed its final review.
New findings could help keep satellites and space debris from colliding Half a million objects, including debris, satellites, and the International Space Station, orbit the planet in the thermosphere, the largest layer of Earth's atmosphere. To predict the orbits—and potential collisions—of all this stuff, scientists must forecast the weather in the thermosphere.

Medicine & Health news

Tumor suppressor also inhibits key property of stem cells A protein that plays a critical role in preventing the development of many types of human cancers has been shown also to inhibit a vital stem cell property called pluripotency, according to a study by researchers at the Stanford University School of Medicine.
	Psychiatrist suggests better tracking of positive drug side-effects that improve mental health (Medical Xpress)—Noted British psychiatrist and former advisor to the British government, David Nutt is suggesting in a World View column in the journal Nature, that a means be created for noting side-effects of drugs that offer improvements in mental health maladies. He suggests that a database be created that allows people with mental illnesses who inadvertently experience improvements in mental health by taking drugs for other reasons, to submit their findings, because it might lead to the discovery of new mental health therapies.
	Researchers getting closer to understanding why odors are so difficult to describe (Medical Xpress)—Ask someone to describe something they are looking at, and they will offer words that have evolved to describe seen objects, but ask them to describe odors, and they will almost always use comparative words based on detection of prior odors. Why this is has puzzled scientists for quite some time, though now it appears that some are getting closer. One team working at Northwest University has been using brain scans to understand what happens when we try to identify smells—they've published a paper describing their findings in The Journal of Neuroscience. Meanwhile, another team has been studying the differences between cultures and how they describe odors and have found that some do a much better job than others. They published a paper earlier this year in the journal Cognition.
	Team develops novel method to prevent, cure rotavirus infection Activation of the innate immune system with the bacterial protein flagellin could prevent and cure rotavirus infection, which is among the most common causes of severe diarrhea, says a Georgia State University research team that described the method as a novel means to prevent and treat viral infection.
	Direct drug screening of patient biopsies could overcome resistance to targeted therapy A new screening platform using cells grown directly from tumor biopsy samples may lead to truly individualized treatment strategies that would get around the problem of treatment resistance, which limits the effectiveness of current targeted therapy drugs. In a paper that will appear in Science and is receiving advance release on the Science Express website, researchers from the Massachusetts General Hospital (MGH) Cancer Center describe how screening samples grown from treatment-resistant tumors against a panel of current and potential targeted therapy drugs identified previously unknown resistance mechanisms, several of which could not be found by gene sequencing.
	Total recall: The science behind it Is it possible to change the amount of information the brain can store? Maybe, according to a new international study led by the Research Institute of the McGill University Health Centre (RI-MUHC). Their research has identified a molecule that puts a brake on brain processing and when removed, brain function and memory recall is improved. Published in the latest issue of Cell Reports, the study has implications for neurodevelopmental and neurodegenerative diseases, such as autism spectral disorders and Alzheimer's disease.
Pre-pregnancy body weight affects early development of human embryos New research indicates that the embryos of women who are overweight or obese at the time they conceive display distinct differences in early development compared to embryos from women of a healthy weight.
Moms with rheumatoid arthritis more likely to give birth prematurely Researchers from Denmark and the U.S. report that babies of women with rheumatoid arthritis (RA) or pre-clinical RA—the period prior to symptoms—are 1.5 times more likely to be born prematurely in Denmark. Findings published in Arthritis & Rheumatology, a journal of the American College of Rheumatology (ACR), indicate that body measurements of the baby at birth were only slightly lower in children exposed to maternal or preclinical RA compared to those with no exposure to the disease. Paternal RA was not found to impact fetal growth or preterm birth risk.
Video tool improves health literacy in prostate patients A video-based tool given to prostate cancer patients significantly improved their understanding of key terms essential to making decisions about prostate cancer treatment, according to a study initiated by the Winship Cancer Institute of Emory University and published today in Cancer, the peer-reviewed journal of the American Cancer Society.
	Researcher develops an injectable antidote for carbon monoxide poisoning When Joseph Roderique was a first-year student in the Virginia Commonwealth University School of Medicine, he had an idea for an injectable antidote for carbon monoxide poisoning. It was a big idea, one that could have dramatic and wide-ranging results if he could make it work.
Sleep disorders found to be highly prevalent in firefighters Sleep disorders are independent risk factors for heart attacks and motor vehicle crashes, which are the two leading causes of death for firefighters in the United States. In a national sample of almost 7,000 firefighters, researchers at Brigham and Women's Hospital (BWH) examined the prevalence of common sleep disorders and their association with adverse health and safety outcomes and found that sleep disorders are highly prevalent, and associated with substantially increased risk of motor vehicle crashes and cardio-metabolic diseases among firefighters.
Hedgehog signaling pathway for breast cancer identified Molecules called long non-coding RNAs (lncRNAs) have been implicated in breast cancer but exactly why they cause metastasis and tumor growth has been little understood...until now.
	Molecular time signalling controls stem cells during brain's development Researchers at Karolinska Institutet in Sweden have succeeded in explaining how stem cells in the brain change to allow one type of stem cell to produce different cell types at different stages. In a study being published in the journal Neuron, researchers show that the signal molecule TGF-beta acts as a time signal that regulates the nerve stem cells' potential at different stages of the brain's development - knowledge that may be significant for future pharmaceutical development.
	Next-gen polio vaccine tackles wild virus emergency Vaccine technology being developed at The University of Queensland could hold the key to completely eradicating polio by removing live virus from the vaccine production process.
	Researchers report breakthrough in qualitative and reliable EEG monitoring systems At next week's Neuroscience 2014, held Nov. 15-19 in Washington, D.C., nanoelectronics research center imec and Holst Centre will present their next-generation wireless electroencephalography (EEG) headset achieving increased EEG data quality. The headset combines dry electrodes with integrated skin-to-electrode impedance monitoring to provide information about the contact quality throughout the entire EEG recording. Unique signal processing is integrated to cancel out motion artefacts. This breakthrough technology paves the way to wireless EEG monitoring solutions for environments without specialized technical assistance, such as at family doctors, psychiatrists, paramedic care, ICU or even at home.
	The geographic origin of AIDS is now known A study published in Science magazine reveals for the first time where, when and how the world's AIDS pandemic originated. Thanks to a statistical analysis of all the genetic data available on the human immunodeficiency virus (HIV), an international research team has just confirmed that the scourge broke out in 1920 in Kinshasa, the capital of what is now the Democratic Republic of the Congo. By comparing this result with historical data, researchers explain how, from a single contamination by a chimpanzee, HIV spread to humans.
	Integrating force feedback into therapies for impaired hands The Hong Kong Polytechnic University has successfully developed a novel training programme using haptic technology for impaired hands that cannot function normally. This programme is unique as it provides force feedback, which creates a true sense of weight to the user through the control device.
	The real disease burden of foodborne infections in Denmark Campylobacter is the foodborne bacteria that contributes most to the burden of disease in Denmark. This is the finding of a study from the National Food Institute, Technical University of Denmark, which for the first time in Denmark ranks three foodborne bacteria according to the burden of disease they impose on society as a whole. The study provides authorities and other decision makers with the scientific basis to prioritize initiatives aimed at increasing food safety and reducing the health consequences of infection with one of the three bacteria.
Study finds marked benefits for cancer prevention with a higher intake of fatty fish A new research review published today will once again have people asking for a second helping of wild Alaskan salmon at the dinner table. While several other studies have recently challenged the long-held belief of the benefits of a diet high in omega-3 fatty acids, this new study led by Saint Luke's Mid America Heart Institute Cardiovascular Research Scientist James J. DiNicolantonio, PharmD, cites compelling evidence that eating the right kinds of fatty fish, in the right quantity, and prepared the right way, can in fact help prevent the body's development of adenocarcinomas, a common type of cancerous tumor. A high proportion of the cancers arising in the breast, prostate, pancreas, colon, and the rest of the gastrointestinal tracts are adenocarcinomas.
Cancer-killing virus combined with a chemotherapy drug might effectively treat recurrent ovarian cancer In six out of 10 cases, ovarian cancer is diagnosed when the disease is advanced and five-year survival is only 27 percent. A new study suggests that a cancer-killing virus combined with a chemotherapy drug might safely and effectively treat advanced or recurrent forms of the disease.
	Personality predicts our driving behaviour Personality traits can be used to predict a lot about a person. They can tell about their probable career success, if they're likely to get divorced, their risk at dying early from disease – and now, how safe they are as drivers.
	What about the mental health of kids with intellectual disability? High-quality epidemiological research shows children and adolescents with intellectual disability are four times more likely to have diagnosable mental health problems compared to others their age. This mental health inequality clearly needs attention.
	Preventing iPosture pain Technology has its benefits but sometimes it can be a pain in the neck – literally. Health care professionals often use the terms "text neck" or "iPosture" to describe the position we take when using our electronic devices, which can often lead to headaches, back pain, and aching shoulders. And for younger users, there are long-term health consequences for their developing bodies.
	New treatment strategies in race against rapidly evolving 'bugs' Evolution kills people. Andrew Read has been saying so for years. But he never actually saw it firsthand until he worked this summer in a hospital in Ann Arbor, Michigan.

Patients around the country are having a hard time booking appointments for outpatient care, and face significant hurdles when it comes to receiving inpatient psychiatric care. Why is this the case?
Studying links between EI and delinquency Young women with high levels of emotional intelligence (EI) are far more likely to engage in delinquency than their male counterparts, and those with apparently lower ability to regulate their emotions.
	Researchers create new guide to help men lose weight A new 'How to' guide launched today by the Men's Health Forum charity - and based on research led by the University of Aberdeen - is the first to show how to adapt and run weight-loss programmes so they are tailored specifically for men.
Cold-induced pain linked to the garlic and mustard receptor Some people experience cold not only as feeling cold, but actually as a painful sensation. This applies even to fairly mild temperatures – anything below 20°C. A group of researchers from Lund University in Sweden have now identified the mechanism in the body that creates this connection between cold and pain. It turns out that it is the same receptor that reacts to the pungent substances in mustard and garlic.
	Genetic testing could improve breast cancer prevention Scientists used mathematical models to show that analysing genetic data, alongside a range of other risk factors, could substantially improve the ability to flag up women at highest risk of developing breast cancer.
Novel cancer vaccine approach for brain tumors Glioblastoma is the most common aggressive primary brain tumor, and despite advances in standard treatment, the median survival is about 15 months (compared to 4 months without treatment). Researchers at Thomas Jefferson University have been working on a cancer vaccine that would extend that survival by activating the patient's immune system to fight the brain tumor. A study published online November 13th in the journal Cancer Immunology, Immunotherapy drilled down to the cellular and molecular mechanisms behind the vaccine, paving the way for further development and refinement of this new experimental treatment.
African Americans at greater risk from stroke and other cerebrovascular diseases Researchers at The University of Texas have found that compared to Caucasian Americans, African Americans have impaired blood flow regulation in the brain that could contribute to a greater risk of cerebrovascular diseases such as stroke, transient ischaemic attack ("mini stroke"), subarachnoid haemorrhage or vascular dementia. These findings were published in Experimental Physiology.
Premature infants exposed to unsafe levels of chemical in medical products Hospitalized premature infants are exposed to unsafe levels of a chemical found in numerous medical products used to treat them, raising questions about whether critically ill newborns may be adversely affected by equipment designed to help save their lives.

Genotype found in 30 percent of ALS patients speeds up disease progression Mice bred to carry a gene variant found in a third of ALS patients have a faster disease progression and die sooner than mice with the standard genetic model of the disease, according to Penn State College of Medicine researchers. Understanding the molecular pathway of this accelerated model could lead to more successful drug trials for all ALS patients.
Oxytocin helps to better overcome fear Frightening experiences do not quickly fade from memory. A team of researchers under the guidance of the University of Bonn Hospital has now been able to demonstrate in a study that the bonding hormone oxytocin inhibits the fear center in the brain and allows fear stimuli to subside more easily. This basic research could also usher in a new era in the treatment of anxiety disorders. The study has already appeared in advance online in the journal Biological Psychiatry. The print edition will be available in a few weeks.
	Researchers discover that the liver and brain communicate in order to regulate appetite The liver stores excess glucose, sugar, in the form of glycogen—chains of glucose—, which is later released to cover body energy requirements. Diabetic patients do not accumulate glucose well in the liver and this is one of the reasons why they suffer from hyperglycemia, that is to say, their blood sugar levels are too high.
	Software to automatically outline bones in X-rays Amidst a national shortage of radiographers in the UK and an increasing requirement for researchers to work with large databases of radiograph images, the software which is being funded by the Engineering and Physical Sciences Research Council, is being designed to automatically pick out the shapes of bones in the images, rather than relying on individual researchers.
Study finds Alzheimer's drug may reduce the urge to binge eat The Alzheimer's drug memantine may perform double-duty helping binge eaters control their compulsion. Researchers have demonstrated that memantine, a neuroprotective drug, may reduce the addictive and impulsive behavior associated with binge eating.
Legally prescribed opioid use may increase mortality in chronic pain patients Associations between opioid-related overdoses and increased prescription of opioids for chronic noncancer pain are well known. But some suggest that overdose occurs predominately in individuals who obtain opioids from nonmedical sources. In a new study published in the November issue of the journal Pain, researchers in Denmark found an increased risk of death associated with chronic pain without opioid treatment, as well as an even higher risk among those prescribed opioids for long-term use and a somewhat lower risk associated with short-term use.
	Scientists develop scoring scheme that predicts ability of cancer cells to spread Scientists at the Cancer Science Institute of Singapore (CSI Singapore) at the National University of Singapore (NUS) and their collaborators have developed a scoring scheme that predicts the ability of cancer cells to spread to other parts of the body, a process known as metastasis. This system, which is the first of its kind, opens up the possibility to explore new treatments that suppress metastasis in cancer patients. The findings were published in EMBO Molecular Medicine in September.

Researchers identify estrogen's role in regulating common health disease risks What makes some women more susceptible to heart disease than others? To help answer that question, researchers at Western University's Robarts Research Institute have identified that an estrogen receptor, previously shown to regulate blood pressure in women, also plays an important role in regulating low-density lipoprotein (LDL) cholesterol levels. LDL, also known as bad cholesterol, drives the process that leads to heart disease.
	New Alzheimer's-related memory disorder identified A multi-institutional study has defined and established criteria for a new neurological disease closely resembling Alzheimer's disease called primary age-related tauopathy (PART). Patients with PART develop cognitive impairment that can be indistinguishable from Alzheimer's disease, but they lack amyloid plaques. Awareness of this neurological disease will help doctors diagnose and develop more effective treatments for patients with different types of memory impairment.
'Tis the season to indulge in walnuts Researchers at UC Davis and other institutions have found that diets rich in whole walnuts or walnut oil slowed prostate cancer growth in mice. In addition, both walnuts and walnut oil reduced cholesterol and increased insulin sensitivity.

Patients suffering from hip fracture receive higher quality of care in smaller hospitals For several years the Danish health service has been moving towards increased centralisation and specialisation in large hospital departments based on the thesis that this provides better results for patients. A new study involving more than 12,000 Danish patients with hip fractures presents a different picture, however:
	Clinical trials on tap for possible Ebola vaccine A top U.S. health official says long-anticipated clinical trials of a possible Ebola vaccine will start soon in West Africa, as the global response to the outbreak took on added urgency with new cases in Mali and reports that the death toll has surpassed 5,000.
Many dialysis patients unprepared for emergencies and disasters Patients on dialysis are very vulnerable during emergencies or disasters, but many are unprepared for such situations, according to two studies that will be presented at ASN Kidney Week 2014 November 11-16 at the Pennsylvania Convention Center in Philadelphia, PA.
New theory may help demystify pregnancy-related condition Preeclampsia, a late-pregnancy disorder that is characterized by high blood pressure and organ damage, may be caused by problems related to meeting the oxygen demands of the growing fetus, experts say in a new Anaesthesia paper.
	Response to Ebola needs flexibility, experts say Many beds are empty at newly opened Ebola treatment units in Liberia's urban centers because the outbreak is now flaring in more rural parts of the country. In Sierra Leone's capital, there aren't enough treatment units as the epidemic spreads there.
	Sharpening state spending on seniors As our society ages, a University of Montreal study suggests the health system should be focussing on comorbidity and specific types of disabilities that are associated with higher health care costs for seniors, especially cognitive disabilities. Comorbidity is defined as the presence of multiple disabilities. Michaël Boissonneault and Jacques Légaré of the university's Department of Demography came to this conclusion after assessing how individual factors are associated with variation in the public costs of healthcare by studying disabled Quebecers over the age of 65 who live in private homes. "Healthcare spending accounts for a growing share of the budgets of economically developed countries. While technological innovations have been identified as the main driver of the increase in costs in recent decades, population aging could contribute more in the years to come. It is therefore important to understand the individual characteristics associated with the high costs of health care," Légaré said.
