Astronomy & Space news

	Researcher shows that black holes do not exist Black holes have long captured the public imagination and been the subject of popular culture, from Star Trek to Hollywood. They are the ultimate unknown – the blackest and most dense objects in the universe that do not even let light escape. And as if they weren't bizarre enough to begin with, now add this to the mix: they don't exist.
	New milestone in the search for water on distant planets Astronomers have found water vapor in the atmosphere of a planet about four times bigger than Earth, in the constellation Cygnus about 124 light years - or nearly 729 trillion miles - from our home planet. In the quest to learn about planets beyond our solar system, this discovery marks the smallest planet for which scientists have been able to identify some chemical components of its atmosphere.
	Mars mission opens India for space business (Update) India celebrated putting a spacecraft into orbit around Mars on Wednesday, hoping the rare feat will show the world it is open for business in space exploration and inspire a new generation of homegrown scientists to help drive growth.
	Solar explosions inside a computer Strong solar flares can bring down communications and power grids on Earth. By demonstrating how these gigantic eruptions are caused, ETH physicists are laying the foundations for future predictions.
	Most stars are born in clusters, some leave 'home' New modeling studies from Carnegie's Alan Boss demonstrate that most of the stars we see were formed when unstable clusters of newly formed protostars broke up. These protostars are born out of rotating clouds of dust and gas, which act as nurseries for star formation. Rare clusters of multiple protostars remain stable and mature into multi-star systems. The unstable ones will eject stars until they achieve stability and end up as single or binary stars. The work is published in The Astrophysical Journal.
	Most metal-poor star hints at universe's first supernovae A team of researchers, led by Miho N. Ishigaki, at the Kavli IPMU, The University of Tokyo, pointed out that the elemental abundance of the most iron-poor star can be explained by elements ejected from supernova explosions of the universe's first stars. Their theoretical study revealed that massive stars, which are several tens of times more immense than the Sun, were present among the first stars. The presence of these massive stars has great implications on the theory of star formation in the absence of heavy elements.
	ESA spaceplane on its way The Intermediate eXperimental Vehicle is ready to fly and left the Netherlands today for the launch site in French Guiana.
	Signs of the formation of a planetary system around the star HD169142 Planets are formed from disks of gas and dust that orbit around young stars. Once the "seed" of the planet —composed of a small aggregate of dust— is formed, it will continue to gather material and it will carve out a cavity or gap in the disk along its orbital path.
	Why is everyone vying for a piece of Mars? The red planet is about to welcome a new visitor: India's Mars Orbiter Mission (MOM) started orbiting Mars on September 24. But MOM is not the only new kid in town. The American MAVEN explorer arrived at the planet on September 21.
	Evidence of gravity waves clouded by interstellar dust In March, scientists working on the BICEP2 experiment, a microwave telescope based at the South Pole, announced that they had seen 'gravity waves' from the early universe, created just after the Big Bang. Ever since the announcement, the cosmological community has been excitedly debating the implications of their detection.
	The origin of Uranus and Neptune elucidated? A team of French-American researchers led by the UTINAM Institute (CNRS/Université de Franche-Comté) has just proposed a solution to the problematic chemical composition of Uranus and Neptune, thus providing clues for understanding their formation. The researchers focused on the positioning of these two outermost planets of the Solar System, and propose a new model explaining how and where they formed. Their results have been published in The Astrophysical Journal on September 20.
	What is the geometry of the universe? One of the big questions in cosmology regards the shape of the universe. "Shape" in this case is not the distribution of galaxies, but rather the shape of space and time itself. In general relativity, space and time can be warped by masses (producing the effect of gravity), and it can be warped by dark energy (producing cosmic expansion). Knowing the shape of the cosmos lets us determine if it is finite in size or infinite, and whether it will expand forever or collapse back upon itself.
	Coronal mass ejections at Mars Looking across the Mars landscape presents a bleak image: a barren, dry rocky view as far as the eye can see. But scientists think the vista might once have been quite different. It may have teemed with water and even been hospitable to microbial life. What changed?
	New ISERV tool enables rapid view of Earth images from space Flipping through online photo albums and social media collections of "selfies" is one thing, but when pictures can show land areas where millions of people live, it can put things in a completely different perspective - especially for scientists.
	Who are the two new arrivals at Mars? As I write this, a team of engineers and scientists will be nervously watching the clock (in fact they are probably in their beds not sleeping). They are waiting for the time when the Mars Orbiter Mission (or MOM) will fire its thrusters and start a gravitational pas-de-deux with Mars.
	NASA image: Sunrise at the Soyuz launch pad The sun rises as the Soyuz TMA-14M spacecraft is rolled out by train to the launch pad at the Baikonur Cosmodrome, Kazakhstan, Sept. 23, 2014.
	A challenging series of occultations this weekend and more Got clear skies? This week's equinox means the return of astronomical Fall for northern hemisphere observers and a slow but steady return of longer nights afterwards. And as the Moon returns to the evening skies, all eyes turn to the astronomical action transpiring low to the southwest at dusk.

Medicine & Health news

	New analysis of human genetic history reveals female dominance Female populations have been larger than male populations throughout human history, according to research published today in the open access journal Investigative Genetics. The research used a new technique to obtain higher quality paternal genetic information to analyse the demographic history of males and females in worldwide populations.
	Researchers find clues to superbug evolution Imagine going to the hospital with one disease and coming home with something much worse, or not coming home at all. With the emergence and spread of antibiotic-resistance pathogens, healthcare-associated infections have become a serious threat. On any given day about one in 25 hospital patients has at least one such infection and as many as one in nine die as a result, according to the Centers for Disease Control and Prevention.
	Imaging studies open a window on how effective antibodies are formed Sometimes, in order to understand what's happening in the immune system, you just have to watch it. By imaging the immune response, researchers have observed how two types of immune cells, T and B cells, interact with one another during a critical period following infection in order to prepare the best antibodies and establish long-lasting protection. Their surprising finding: T cells and B cells form numerous short-term contacts, each lasting no more than a few minutes, in a dynamic process that is very different from how T cells interact with other cell types. The results were recently published in Science.
	Brain scans reveal true nature of muscle control in 'floating arm trick' (Medical Xpress)—A trio of neuroscientists has learned more about what the brain does during the "floating arm trick" by enlisting volunteers who underwent brain scans while performing the trick. In their paper published in Proceedings of the Royal Society B: Biological Sciences, Arko Gosh, John Rothwell and Patrick Haggard, describe their ideas leading into the experiment and what they learned from the brain scans.
	How a single, genetic change causes retinal tumors in young children Retinoblastoma is a childhood retinal tumor usually affecting children one to two years of age. Although rare, it is the most common malignant tumor of the eye in children. Left untreated, retinoblastoma can be fatal or result in blindness. It has also played a special role in understanding cancer, because retinoblastomas have been found to develop in response to the mutation of a single gene – the RB1 gene—demonstrating that some cells are only a step away from developing into a life-threatening malignancy.
	Brain scans reveal 'gray matter' differences in media multitaskers Simultaneously using mobile phones, laptops and other media devices could be changing the structure of our brains, according to new University of Sussex research.
	Scientists use stem cells to learn how common mutation in Asians affects heart health Over 500 million people worldwide carry a genetic mutation that disables a common metabolic protein called ALDH2. The mutation, which predominantly occurs in people of East Asian descent, leads to an increased risk of heart disease and poorer outcomes after a heart attack. It also causes facial flushing when carriers drink alcohol.
	Immune activity shortly after surgery holds big clue to recovery rate, study finds The millions of people who undergo major surgery each year have no way of knowing how long it will take them to recover from the operation. Some will feel better within days. For others, it will take a month or more. Right now, doctors can't tell individual patients which category they'll fit into.
	From rats to humans: Project NEUWalk closer to clinical trials Lausanne, Switzerland. EPFL scientists have discovered how to control the limbs of a completely paralyzed rat in real time to help it walk again. Their results are published today in Science Translational Medicine.
Family-based therapies can treat anorexia in teens, study finds Two different family-based therapies are both effective at combating anorexia nervosa in teenagers, according to the largest study ever to compare two such treatments for the life-threatening eating disorder.
First mouse model for ALS dementia The first animal model for ALS dementia, a form of ALS that also damages the brain, has been developed by Northwestern Medicine scientists. The advance will allow researchers to directly see the brains of living mice, under anesthesia, at the microscopic level. This will allow direct monitoring of test drugs to determine if they work.
Modest effect of statins on diabetes risk and bodyweight related to mechanism of action The mechanism by which statins increase the risk of type 2 diabetes has been investigated in a large-scale analysis from an international team led by researchers from UCL and the University of Glasgow, using information from genetic studies and clinical trials.
	New EEG electrode set for fast and easy measurement of brain function abnormalities A new, easy-to-use EEG electrode set for the measurement of the electrical activity of the brain was developed in a recent study completed at the University of Eastern Finland. The solutions developed in the PhD study of Pasi Lepola, MSc, make it possible to attach the electrode set on the patient quickly, resulting in reliable results without any special treatment of the skin. As EEG measurements in emergency care are often performed in challenging conditions, the design of the electrode set pays particular attention to the reduction of electromagnetic interference from external sources.
	Protein Mfn2 may increase the currently short therapeutic window in stroke A new study published in the prestigious publication The EMBO Journal shows that the mitochondrial protein Mfn2 may be a future therapeutic target for neuronal death reduction in the late phases of an ischemic stroke. The study has been coordinated by Dr Francesc Soriano, Ramón y Cajal researcher at the Department of Cell Biology of the University of Barcelona (UB) and member of the Research Group Celltec UB.

Researchers develop new anticancer peptide vaccines and inhibitors (Medical Xpress)—Researchers have developed two new anticancer peptide vaccines and two peptide inhibitors as part of a larger peptide immunotherapy effort led by investigators at The Ohio State University Comprehensive Cancer Center – Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC – James).
	Details of monkey antibodies against chikungunya virus could help to fight the disease in humans Chikungunya fever can cause severe and long-lasting joint pain, with several epidemics affecting multiple continents in the past decade. The illness is caused by chikungunya virus (CHIKV), but there is no effective vaccine or drug against it. Now, research led by Lisa Ng from the A*STAR Singapore Immunology Network provides details of how the immune system responds to CHIKV—findings that could support the development of vaccines and therapies.
	Dual-action chemical agents improve a high-resolution and noninvasive way to detect cancer Concerns over toxicity have constrained the clinical application of photoacoustic imaging—a new experimental technique used to detect tumors lurking among healthy cells. A*STAR researchers from the Singapore Bioimaging Consortium and an international team have now discovered how to improve both the safety and the tumor-locating efficacy of photoacoustic imaging using 'photosensitizer' contrast agents.
	Organ donation – do we opt-in or opt-out? Researchers say there should be an international data base containing the very latest information about organ donations and transplants so policy makers can make informed decisions on whether to adopt an opt-out or opt-in system.
	Bowel cancer patients may do better if diagnosed through screening Although bowel cancer screening usually detects cancer at an earlier stage, new research indicates that when screening detects a late stage cancer patients may be more likely to survive than those whose late stage cancer is only diagnosed after developing symptoms.
	Ageing isn't fixed—we can manipulate it to live longer When I was younger, about ten years old, I realised that everyone ages and dies. And I thought well why should that be? Can't we do something about it? I then thought I'd do it. I'll study ageing and figure it out, and I'll find a solution so people don't have to age and die. And that's what I do today.
Cardiorespiratory fitness is often misdiagnosed A recent study by the University of Eastern Finland shows that scaling maximal oxygen uptake and maximal workload by body weight confounds measures of cardiorespiratory fitness. It has been a common practice in exercise testing to scale the results by body weight and, according to researchers, this practice should be abandoned. More reliable data on cardiorespiratory fitness can be observed by using lean mass proportional measures. The results were published recently in Clinical Physiology and Functional Imaging.
	Teens world-wide self-medicate with over-the-counter and prescription drugs Adolescents around the world are frequently using over-the-counter and prescription medications without a doctor's order, a risky practice that can lead to overuse and abuse and is often continued into adulthood, reveals a new review in the Journal of Adolescent Health.
	Child maltreatment alters hormone levels linked to obesity (Medical Xpress)—Children who are maltreated may be at an increased risk of obesity and inflammatory disorders because of low levels of leptin—a hormone involved in regulating appetite, according to new research from King's College London.
New intervention in the fight against bowel cancer It is widely known that bowel cancer is often driven by increased tumour cell survival and proliferation mediated by the deregulation of a key mechanism within gut cells controlled by the protein Wnt.
Higher risk of autism found in children born at short and long interpregnancy intervals A study published in the MONTH 2014 issue of the Journal of the American Academy of Child and Adolescent Psychiatry found that children who were conceived either less than 1 year or more than 5 years after the birth of their prior sibling were more likely to be diagnosed with autism than children conceived following an interval of 2-5 years.
	Children can be trained recognise emotions Children can using training to spot crucial cues on someone's emotional state, new research from the University of Lincoln, UK, has show.
First screen for genetic risk factors of IBS in the general population In the largest gene-hunting effort ever conducted in irritable bowel syndrome, IBS, researchers have found that some regions in the genome may be associated with an increased risk of developing the disease. The results from the international study led by researchers at Karolinska Institutet are published in the journal Gut.
	States need to assume greater role in regulating dietary supplements Dietary supplements, which are marketed to adults and adolescents for weight loss and muscle building, usually do not deliver promised results and can actually cause severe health issues, including death. But because of lax federal oversight of these supplements, state governments need to increase their regulation of these products to protect consumers.
	Researchers identify brain areas activated by itch-relieving drug Areas of the brain that respond to reward and pleasure are linked to the ability of a drug known as butorphanol to relieve itch, according to new research led by Gil Yosipovitch, MD, Professor and Chairman of the Department of Dermatology at Temple University School of Medicine (TUSM), and Director of the Temple Itch Center. The findings point to the involvement of the brain's opioid receptors—widely known for their roles in pain, reward, and addiction—in itch relief, potentially opening up new avenues to the development of treatments for chronic itch.
Many elite college athletes return to play after ACL surgery The majority of athletes included in a new study by researchers at the University of North Carolina School of Medicine were able to return to play after having knee surgery to repair an anterior cruciate ligament (ACL) injury.
	Most breast cancer patients who had healthy breast removed at peace with decision More women with cancer in one breast are opting to have both breasts removed to reduce their risk of future cancer. New research shows that in the long term, most have no regrets. Mayo Clinic surveyed hundreds of women with breast cancer who had double mastectomies between 1960 and 1993 and found that nearly all would make the same choice again. The findings are published in the journal Annals of Surgical Oncology.
	Tonsil stem cells could someday help repair liver damage without surgery The liver provides critical functions, such as ridding the body of toxins. Its failure can be deadly, and there are few options for fixing it. But scientists now report in the journal ACS Applied Materials & Interfaces a way to potentially inject stem cells from tonsils, a body part we don't need, to repair damaged livers—all without surgery.
Skin cells can be engineered into pulmonary valves for pediatric patients Researchers have found a way to take a pediatric patient's skin cells, reprogram the skin cells to function as heart valvular cells, and then use the cells as part of a tissue-engineered pulmonary valve. A proof of concept study published in the September 2014 issue of The Annals of Thoracic Surgery provides more detail on this scientific development.
Good news for young patients with a leukemia subtype associated with a poor prognosis St. Jude Children's Research Hospital investigators found that adjusting treatment based on early response to chemotherapy made a life-saving difference to young patients with an acute lymphoblastic leukemia (ALL) subtype associated with a poor outcome. The study appeared in the September 20 edition of the Journal of Clinical Oncology.

The plus side of population aging Around the world, people are living longer and having fewer children, leading to a population that is older, on average, than in the past. On average, life expectancy in developed countries has risen at a pace of three months per year, and fertility has fallen below replacement rate in the majority of Europe and other developed countries.
	Think you have Alzheimer's? You just might be right, study says New research by scientists at the University of Kentucky's Sanders-Brown Center on Aging suggests that people who notice their memory is slipping may be on to something.
Clinical trial examined treatment for complicated grief in older individuals Bottom Line: A treatment designed to help older individuals deal with complicated grief (CG) after the loss of a loved one appeared to be more effective than using a treatment designed for depression.
	Alzheimer's patients can still feel the emotion long after the memories have vanished A new University of Iowa study further supports an inescapable message: caregivers have a profound influence—good or bad—on the emotional state of individuals with Alzheimer's disease. Patients may not remember a recent visit by a loved one or having been neglected by staff at a nursing home, but those actions can have a lasting impact on how they feel.
