Astronomy & Space news
Searching for water in the atmosphere of a Neptune-mass exoplanet HAT-P-26b(Phys.org)—HAT-P-26b is an inflated, Neptune-mass exoplanet located about 437 light years from Earth, which orbits its parent star HAT-P-26 every 4.23 days. The planet has a relatively low surface gravity that is well suited for atmospheric characterization. However, we still know very little about the gas layer around this distant alien world. A team of astronomers led by Kevin B. Stevenson of the University of Chicago wants to change that, presenting new insights on the atmosphere of this celestial body. | |

No fireworks in the galactic centerThe center of our Milky Way galaxy, about twenty-five thousand light years from Earth, is invisible to us in optical light because of the extensive amounts of absorbing, intervening dust. Radiation at many other wavelengths, however, including the infrared, radio, and energetic X-rays, can penetrate the veiling material. At the heart of the galactic center is a supermassive black hole, SagA*, with about four million solar-masses of material. It is a relatively dim object, and shows some slight flickering that is thought to be the result of small blobs of material randomly accreting onto a disk around it. Its general passivity distinguishes SagA* from many other supermassive black holes in other galactic centers that actively accrete and heat large amounts of material, and then eject powerful bipolar jets of fast-moving charged particles. | |
Rotational clock for stars needs recalibrationNew work from a team of astronomers led by Carnegie's Jennifer van Saders indicates that one recently developed method for determining a star's age needs to be recalibrated for stars that are older than our Sun. This is due to new information about the way older stars spin, as spin rate is one of the few windows into stellar ages. Their findings, published in Nature, have implications for our own Solar System, as they indicate that our own Sun might be on the cusp of a transition in its magnetic field. | |
Will 2016 be the year Elon Musk reveals his Mars colonial transporter plans?There are several space stories we're anticipating for 2016 but one story might appear—to some—to belong in the realm of science fiction: sometime in the coming year Elon Musk will likely reveal his plans for colonizing Mars. | |

Two studies show father's diet can impact on offspring(MedicalXpress)—Two teams of researchers conducting independent experiments have found evidence that indicates that what a male mouse eats prior to mating with a female mouse can have an impact on the offspring that result. The first group, from several institutions in China, ran experiments testing the impact of male mice eating a high fat diet, on offspring, while the second team, with members from the U.S. and Canada, tested the impact of a low-protein diet by male mice prior to siring offspring. Both teams describe their experiments and results in papers published in the journal Science. | |
Researchers identify the brain circuits involved in anhedonia in rats(MedicalXpress)—A combined team of researchers from Stanford and Cornell University's has found what they believe to be the brain circuits that are involved in the development of anhedonia—where a person, or rat, is incapable of feeling pleasure. In their paper published in the journal Science, the team outlines their experiments with rats and why they believe their findings could provide a possible path to curing the disorder in people. Trevor Robbins with the University of Cambridge offers a Perspectives piece on the work done by the team in the same journal issue and outlines possibilities for where such work may head in the future. | |
Using genes to understand the brain's building blocksUnderstanding the cellular building blocks of the brain, including the number and diversity of cell types, is a fundamental step toward understanding brain function. Researchers at the Allen Institute for Brain Science have created a detailed taxonomy of cells in the mouse visual cortex based on single-cell gene expression, identifying 49 distinct cell types in the largest collection of individual adult cortical neurons characterized by gene expression published to date. The work appears this month online in Nature Neuroscience. | |
Scientists find minor flu strains pack bigger punchMinor variants of flu strains, which are not typically targeted in vaccines, carry a bigger viral punch than previously realized, a team of scientists has found. Its research, which examined samples from the 2009 flu pandemic in Hong Kong, shows that these minor strains are transmitted along with the major strains and can replicate and elude immunizations. | |
Do we have free will? Researchers test mechanisms involved in decision-makingOur choices seem to be freer than previously thought. Using computer-based brain experiments, researchers from Charité - Universitätsmedizin Berlin studied the decision-making processes involved in voluntary movements.

Solving the mystery of defective embryosIt's the dream of many infertile couples: to have a baby. Tens of thousands of children are born by in vitro fertilization, or IVF, a technique commonly used when nature doesn't take its course. However, embryos obtained when a sperm fertilizes an egg in a test tube often have defects. In a study published today in the journal Proceedings of the National Academy of Sciences, researchers at the University of Montreal Hospital Research Centre (CRCHUM) discovered an important element in understanding how these anomalies occur in the developing embryo. | |
Research shows that tiny non-fibrous regions within fibrous tissue affect behaviorInjury and degeneration of fibro-cartilaginous tissues, such as the knee meniscus and the intervertebral disc, have significant socioeconomic and quality-of-life costs. But the development of effective treatment strategies to address pathologies in these load-bearing tissues has been hindered by a lack of understanding of the relationships between their structure and their function. | |

Use of anticholinergic drugs does not increase risk for dementia in Parkinson's disease patientsRecent evidence has shown a greater risk of dementia, in particular Alzheimer's disease (AD), in individuals using anticholinergic medications regularly. These drugs are widely used by older adults to treat bladder dysfunction, mood, and pain, and many of them are available without prescription. Since these drugs are often used to treat both motor symptoms and non-motor symptoms in patients with Parkinson's Disease (PD), there is concern for increased risk of dementia. Contrary to expectations, a study in the current issue of the Journal of Parkinson's Disease determined that the cognitive performance of PD patients taking anticholinergic medications did not differ from those who did not. | |

New national perioperative guideline for the delivery of quality care for geriatric surgical patients releasedCHICAGO: Responding to the needs of the country's growing older adult population, a new collaborative best practices guideline was released today for optimal care of older adults immediately before, during, and after surgical operations (a timeframe known as the "perioperative" period). The new consensus-based guideline was developed by the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP®) and the American Geriatrics Society's (AGS) Geriatrics-for- Specialists Initiative (GSI), with support from The John A. Hartford Foundation. With more than 40 million older adults living in the U.S. today—and with that number expected to nearly double to 89 million by 2050*—providing expert guidance on surgical care is key since the need for surgical services increases with age and targeted guidance during the perioperative period can speed recovery. | |
Improving access to clinical trials when biopsies are requiredThe requirement for tumor tissue specimens and associated analyses in order to participate in clinical trials appears to be a significant barrier to clinical trial enrollment and may delay treatment. Potential solutions to reducing or eliminating these barriers include routine tissue banking at diagnosis, easing use of available diagnostic samples, development of less invasive tests, faster turnaround time at central laboratories or allowing for local testing and more resources for timely tissue collection. | |
US emergency departments face serious drug shortagesA new study reveals that drug shortages affecting emergency care have skyrocketed in the United States in recent years.

A worm with five facesFor eight years, a research team headed by Ralf Sommer and Matthias Herrmann travel to Réunion Island in the Indian Ocean. The scientists from the Max Planck Institute of Developmental Biology have now discovered a new nematode species on the island. The discovered nematodes live inside of fig plants and at first sight they look totally different. Much to their surprise, the scientists found that all the worms belong to a single species, which can develop five different mouth forms. The nematodes are genetically identical, however their food source decides on the mouth form. They are an extreme example of evolutionary divergence within a species. | |
An ancient symbiosis founded entirely on exploitation, not mutual benefitBiologists at the universities of Exeter and York have published new research which shows that an ancient symbiosis is founded entirely on exploitation, not mutual benefit. | |
