![]() | NASA observatories take an unprecedented look into superstar Eta CarinaeEta Carinae, the most luminous and massive stellar system within 10,000 light-years of Earth, is known for its surprising behavior, erupting twice in the 19th century for reasons scientists still don't understand. A long-term study led by astronomers at NASA's Goddard Space Flight Center in Greenbelt, Maryland, used NASA satellites, ground-based telescopes and theoretical modeling to produce the most comprehensive picture of Eta Carinae to date. New findings include Hubble Space Telescope images that show decade-old shells of ionized gas racing away from the largest star at a million miles an hour, and new 3-D models that reveal never-before-seen features of the stars' interactions. |
![]() | Unusual light signal yields clues about elusive black hole merger(Phys.org)—The central regions of many glittering galaxies, our own Milky Way included, harbor cores of impenetrable darkness—black holes with masses equivalent to millions, or even billions, of suns. What is more, these supermassive black holes and their host galaxies appear to develop together, or "co-evolve." Theory predicts that as galaxies collide and merge, growing ever more massive, so too do their dark hearts. |
![]() | Where did all the stars go? Dark cloud obscures hundreds of background starsSome of the stars appear to be missing in this intriguing new ESO image. But the black gap in this glitteringly beautiful starfield is not really a gap, but rather a region of space clogged with gas and dust. This dark cloud is called LDN 483—for Lynds Dark Nebula 483. Such clouds are the birthplaces of future stars. The Wide Field Imager, an instrument mounted on the MPG/ESO 2.2-metre telescope at ESO's La Silla Observatory in Chile, captured this image of LDN 483 and its surroundings. |
![]() | Volunteer 'disk detectives' top 1 million classifications of possible planetary habitats(Phys.org) —A NASA-sponsored website designed to crowdsource analysis of data from the agency's Wide-field Infrared Survey Explorer (WISE) mission has reached an impressive milestone. In less than a year, citizen scientists using DiskDetective.org have logged 1 million classifications of potential debris disks and disks surrounding young stellar objects (YSO). This data will help provide a crucial set of targets for future planet-hunting missions. |
![]() | No signals from newest Kepler planetA newly discovered planet has been observed with the Allen Telescope Array in a search for radio signals that would betray technically sophisticated inhabitants, but no transmissions have been detected. |
![]() | Image: First Mars orbital photo of 2015This image was taken on 2 January just after midday GMT, and is one of the first of the Red Planet this year from the low-resolution Visual Monitoring Camera – the 'Mars Webcam' – on ESA's Mars Express orbiter. |
![]() | Princeton satellite successfully heads to the 'edge of space' to study the early universe(Phys.org) —With a noise like giant flags billowing in the wind, the massive white helium balloon rose into the air and carried SPIDER, a telescope designed to investigate the origin of the universe, high above Antarctica. The successful Jan. 1 launch signaled the beginning of a roughly 20-day mission above the continent. |
![]() | Japan's Akatsuki spacecraft to make second attempt to enter orbit of Venus in December 2015Back in 2010, the Japanese Aerospace Exploration Agency (JAXA) launched the The Venus Climate Orbiter "Akatsuki" with the intention of learning more about the planet's weather and surface conditions. Unfortunately, due to engine trouble, the probe failed to make it into the planet's orbit. |
![]() | NOAA's DSCOVR to provide 'EPIC' views of EarthNASA has contributed two Earth science instruments for NOAA's space weather observing satellite called the Deep Space Climate Observatory or DSCOVR, set to launch in January 2015. One of the instruments called EPIC or Earth Polychromatic Imaging Camera will image the Earth in one picture, something that hasn't been done before from a satellite. EPIC will also provide valuable atmospheric data. |

![]() | Scientists train immune system to spot and destroy cure-defying mutant HIVLuring dormant HIV out of hiding and destroying its last cure-defying holdouts has become the holy grail of HIV eradication, but several recent attempts to do so have failed. Now the findings of a Johns Hopkins-led study reveal why that is and offer a strategy that could form a blueprint for a therapeutic vaccine to eradicate lingering virus from the body. |
![]() | New approach sees breakthrough in antibiotics researchScientists using a revolutionary approach have devised an antibiotic that may offset the mounting problem of drug resistance for decades, they said on Wednesday. |
![]() | How songbirds may help build a better hearing aid(Medical Xpress)—Untreated hearing loss can have devastating and alienating repercussions on a person's life: isolation, depression, sapped cognition, even dementia. |
![]() | Two brain regions join forces for absolute pitchPeople who have "absolute pitch" can identify notes immediately without relying on a reference tone. Intensive research is being conducted into the neuronal basis of this extraordinary ability at the University of Zurich's Department of Neuropsychology. The researchers have now detected a close functional link between the auditory cortex in the brain and the frontal lobe in these extraordinary people – a discovery that is not only important in theory, but also in practice. |
![]() | Schizophrenia onset linked to elevated neural linksIn its chronic stage, schizophrenia is typically marked by a dearth of links between brain cells in the prefrontal cortex, the region of the brain responsible for higher-order thinking. However, a new study by Yale and Chinese researchers shows that the onset of the disease—usually in the early 20s—is marked by an abnormal spike in neural connections. |
![]() | Was Beethoven's music literally heartfelt? Could cardiac arrhythmia have influenced famous works?Could it be that when Ludwig van Beethoven composed some of the greatest masterpieces of all time that he was quite literally following his heart? |
![]() | Too much gas, too little food appear major factors in injury, disease-related memory lossInflammation plays a role in learning and memory loss that can result from brain Injury or disease, and researchers now have evidence that neurons may be suffering from too much gas and too little food. |
Research shows small proteins called defensins neutralize toxins released by pathogensA small protein active in the human immune response can disable bacterial toxins by exploiting a property that makes the toxins effective - but also turns out to be a weakness. | |
![]() | Research findings have implications for regenerating damaged nerve cellsTwo new studies involving the University of Colorado Boulder and the University of Queensland (UQ) in Brisbane, Australia have identified a unique molecule that not only gobbles up bad cells, but also has the ability to repair damaged nerve cells. |
![]() | Brain scientists figure out how a protein crucial to learning and memory worksResearchers at Johns Hopkins have found out how a protein crucial to learning works: by removing a biochemical "clamp" that prevents connections between nerve cells in the brain from growing stronger. The finding moves neuroscientists a step closer to figuring out how learning and memory work, and how problems with them can arise. A report on the discovery appears Jan. 7 in the journal Neuron. |
![]() | Scientists identify first nutrient sensor in key growth-regulating metabolic pathwayKnown as much for its complexity as its vital role in regulating cellular and organismal growth, the mechanistic target of rapamycin complex 1 (mTORC1) pathway has seemingly been acting in mysterious ways. |
Tracking subtle brain mutations, systematically: Tool can trace and spatially map 'mosaic' mutations in the brainDNA sequences were once thought to be identical from cell to cell, but it's increasingly understood that mutations can arise during brain development that affect only certain groups of brain cells. A technique developed at Boston Children's Hospital allows these subtle mutation patterns to be traced and mapped spatially for the first time. This capability is a significant advance for genetics research and provides a new way to study both the normal brain and brain disorders such as epilepsy and autism. | |
Researchers make new discoveries in key pathway for neurological diseasesA new intermediate step and unexpected enzymatic activity in a metabolic pathway in the body, which could lead to new drug design for psychiatric and neurodegenerative diseases, has been discovered by researchers at Georgia State University. | |

Alcohol sales linked with alcohol deaths across GB regionsFor the first time alcohol sales data, which act as a proxy for alcohol consumption, and alcohol-related deaths for regions in Great Britain have been analyzed. The results, published in the open access journal BMC Public Health, show that of eleven regions analyzed, the South West, Central Scotland, North East, North West and Yorkshire had higher levels of alcohol sales per adult than the GB average. There were lower sales in London, Central England and the East of England. | |
Blood sugar levels in heart failure patients predict risk of early deathNew research suggests that people who arrive at hospital emergency departments with acute heart failure should have their blood sugar levels checked on arrival. This simple and inexpensive measure could identify patients at high risk of early death, further hospitalisations, or the development of more health problems, such as diabetes. | |
More than a third of people with abnormal results drop out of bowel cancer screeningAlmost 40 per cent of people who have abnormal results from bowel cancer screening tests and are referred for further investigation ignore their next screening invitation two years later, according to a Cancer Research UK study* published today in the British Journal of Cancer. | |
![]() | Having a hard time focusing? Research identifies complex of neurons crucial to controlling attentionOur ability to pay attention to certain things while ignoring distractions determines how good we are at a given task, whether it is driving a car or doing brain surgery. A research team at McGill University has for the first time convincingly identified a network of neurons in a particular area of the brain, the lateral prefrontal cortex, that interact with one another to promptly filter visual information while at the same time ignoring distractions. It's a discovery with potentially far reaching implications for people who suffer from diseases such as autism, ADHD and schizophrenia. |
![]() | Variation in ability to ID inappropriate nuclear stress test(HealthDay)—There is modest inter-rater reliability for the 2009 Appropriate Use Criteria for nuclear stress testing and inter-rater variability in identification of inappropriate tests, according to a study published online Jan. 6 in Circulation: Cardiovascular Quality and Outcomes. |

Dog paralysis study shows need for customized treatmentsA clinical trial from North Carolina State University involving paraplegic dogs has demonstrated that a one-size fits all approach is not ideal for treating spinal cord injuries. Instead, the study highlights the fact that the population of canine paraplegics – even those with the same type of injury – are very diverse, and that courses of treatment should be equally so. These findings may lead the way to personalized treatments for spinal cord injuries, and hopefully better outcomes for canine and potentially human patients. | |
![]() | What should a hospital do when critical drugs are in short supply?Four years ago, just before Christmas, my hospital ran out of cytarabine, an essential drug used to treat and cure certain kinds of acute leukemia. This drug was suddenly in short supply across the nation. At Duke, we had enough for about 10 days based upon our historical usage, but after that we could no longer treat those already on therapy or begin treatment for newly diagnosed patients. And we couldn't ask other hospitals in the region to "lend" us some since they were in the same boat. |
![]() | How to get your stress levels in checkStress is the physical and emotional response we all experience when faced with demanding situations. |
![]() | Do ice cream and cold drinks cool us down?All over the world summer is synonymous with water activities, cold beverages and, of course, ice cream. While most of us agree ice cream and cold beverages are refreshing summer treats, do they actually help cool us down? |
![]() | Humans use facial expression to help recall emotionSmiles are contagious, even when we're trying to remember them. A study carried out by a research team of the International School for Advanced Studies (SISSA) of Trieste shows that in order to recall an emotion (positive or negative) we "re-enact" the motor sequence of the facial expression corresponding to that emotion. In other words: when remembering a smile, we smile. |
A head start against tooth decayMassachusetts public health advocates have developed oral health guidelines to ensure the well-being of the 70,000 babies born in the state each year as well as that of their mothers. | |
![]() | Study links TV use and unhealthy eatingThe holidays can be a time for binge watching TV shows or movies. According to a University of Houston (UH) researcher, all of those hours in front of the television may lead to increased snacking. |

![]() | Study disputes previous theories on loss of muscle stem cells and aging(Medical Xpress)—Professional athletes often spend hours in a gym working to build strong healthy muscles needed to keep them at the top of their game. But strong muscles help all humans maintain peak physical performance – the non-athlete, the young and the old – and can prevent frailty later in life, a condition that can exacerbate an illness and even shorten one's life. According to Charlotte Peterson, co-director of the Center for Muscle Biology at the University of Kentucky, "muscle powers health." |
Study suggests that dopamine is safe anti-angiogenic drug in cancer treatmentA new study led by scientists at The Ohio State University Comprehensive Cancer Center - Arthur G.

![]() | Expressing anger linked with better health in some culturesIn the US and many Western countries, people are urged to manage feelings of anger or suffer its ill effects—but new research with participants from the US and Japan suggests that anger may actually be linked with better, not worse, health in certain cultures. The findings are published in Psychological Science, a journal of the Association for Psychological Science. |
Review article estimates annual US cost of psoriasis in 2013The annual U.S. cost of psoriasis, a chronic inflammatory skin condition, was estimated to be between $112 billion and $135 billion in 2013, according to a review article published online by JAMA Dermatology. | |
PTSD doubles diabetes risk in womenWomen with post-traumatic stress disorder are nearly twice as likely to develop type 2 diabetes compared with women who don't have PTSD, according to researchers at the Mailman School of Public Health at Columbia University and Harvard School of Public Health. | |
Brain imaging may help predict future behaviorNoninvasive brain scans, such as functional magnetic resonance imaging, have led to basic science discoveries about the human brain, but they've had only limited impacts on people's day-to-day lives. A review article published in the January 7 issue of the Cell Press journal Neuron, however, highlights a number of recent studies showing that brain imaging can help predict an individual's future learning, criminality, health-related behaviors, and response to drug or behavioral treatments. The technology may offer opportunities to personalize educational and clinical practices. | |
After weight-loss surgery, people could experience discrimination when interviewing for jobsPeople say that they would be more likely to hire someone who has lost weight through exercise and dieting than through surgery. This is just one of the stigmas faced by obese people who undergo weight-reducing bariatric surgery, reports Robert Carels of East Carolina University in the US and his team of researchers. The findings are published in Springer's journal Obesity Surgery. | |
Physical recovery in critically ill patients can predict remission of anxiety and PTSD symptomsIn a two-year longitudinal study involving 13 intensive care units in four U.S. hospitals, researchers found that better physical functioning—basic and complex activities considered essential for maintaining independence—is associated with remission of general anxiety and post-traumatic stress disorder (PTSD) symptoms. These findings may help clinicians be better prepared for caring for the growing number of survivors of critical illness, potentially leading to a better quality of recovery for patients. | |

![]() | Campus debit cards let students buy cigarettes with parents' moneyA University of Colorado Cancer Center study published in the British Medical Journal: Tobacco Control shows that of the top 100 universities as ranked by U.S. News and World Report, 11 allow tobacco sales and 13 allow e-cigarette sales on "campus cash" debit cards that are commonly prepaid by parents. |
Team develops prognostic test for E2F4 in breast cancerBy looking at the expression levels of downstream genes of the regulators in breast cancer, investigators at Dartmouth Hitchcock's Norris Cotton Cancer Center (NCCC), led by Chao Cheng, PhD, have identified a gene signature in E2F4 that is predictive of estrogen receptor positive (ER+) breast cancer. The findings, published in Breast Cancer Research, define a new opportunity for personalizing medicine for women whose Oncotype DX assay results classify them as of "intermediate-risk for recurrence." Until now, there has been no standard of care for those with intermediate risk. Results at NCCC support reclassifying 20-30% of those patients as "high-risk for recurrence," indicating they should receive aggressive follow-up treatment. | |
![]() | Article highlights top technology challenges for 2015(HealthDay)—The introduction of the International Classification of Diseases, 10th Revision (ICD-10), Health Insurance Portability and Accountability Act (HIPAA) audits, meaningful use 2, and the burdens of technology are the top four technological challenges for physicians in 2015, according to an article published in Medical Economics. |

![]() | Misfit or Miss Goody Two Shoes? Adolescent misperceptions aboundIt's true: teens are misunderstood. But apparently, teens themselves have dramatic misperceptions about what their peers are doing when it comes to sex, drugs and studying, possibly prompting them to conform to social norms that don't exist. |
Type 2 diabetes risk varies with magnesium intake, genes and ethnicityMagnesium is an important nutrient, in part because it appears to help regulate insulin secretion and/or action. Sure enough, studies over the last decade have shown that low intake of the mineral is a risk factor for developing type 2 diabetes. But everyone is different, so doctors need to know much more before they can accurately tailor nutritional therapy for patients. A new study in the Journal of Nutrition found several deep, specific interactions of diet, genetics, and ethnicity in determining magnesium-mediated diabetes risk in postmenopausal women. | |
![]() | Restoring vision to the blindScientists have long known that species such as amphibians and fish can regenerate retinal cells—so why can't mammals? This and related questions are the premise for the third report from the Albert and Mary Lasker Foundation and the International Retinal Research Foundation's 10-year collaboration, recently published in the ARVO journal Translational Vision Science & Technology (TVST). |
![]() | Mind-body connection not a one-way streetWe usually think our mind is in control and telling our body what to do. But there is a lot of scientific evidence that shows the chatter between mind and body goes two ways, and the body is an integral part of how we think. In the new book How the Body Knows Its Mind, Prof. Sian Beilock provides the latest scientific evidence about the body's influence on our psyche, drawing on work from her own laboratory and from colleagues around the world. |
