Astronomy & Space news
Violent origins of disc galaxies probed by ALMAFor decades scientists have believed that galaxy mergers usually result in the formation of elliptical galaxies. Now, for the the first time, researchers using the Atacama Large Millimeter/sub-millimeter Array and a host of other radio telescopes have found direct evidence that merging galaxies can instead form disc galaxies, and that this outcome is in fact quite common. This surprising result could explain why there are so many spiral galaxies like the Milky Way in the Universe. | |
Smallest known galaxy with a supermassive black hole foundA University of Utah astronomer and his colleagues discovered that an ultracompact dwarf galaxy harbors a supermassive black hole – the smallest galaxy known to contain such a massive light-sucking object. The finding suggests huge black holes may be more common than previously believed. | |
Pulse of a dead star powers intense gamma rays(Phys.org) —Our Milky Way galaxy is littered with the still-sizzling remains of exploded stars. | |
Dawn operating normally after safe mode triggered(Phys.org) —The Dawn spacecraft has resumed normal ion thrusting after the thrusting unexpectedly stopped and the spacecraft entered safe mode on September 11. That anomaly occurred shortly before a planned communication with NASA's Deep Space Network that morning. The spacecraft was not performing any special activities at the time. | |
Mystery of rare five-hour space explosion explainedNext week in St. Petersburg, Russia, scientists on an international team that includes Penn State University astronomers will present a paper that provides a simple explanation for mysterious ultra-long gamma-ray bursts—a very rare form of the most powerful explosions in the universe. | |
NASA's Maven spacecraft reaches Mars this weekendMars, get ready for another visitor or two. This weekend, NASA's Maven spacecraft will reach the red planet following a 10-month journey spanning 442 million miles (711 million kilometers). | |
Atlas V rocket launches, taking satellite aloftA communications satellite has been launched from the Cape Canaveral Air Force Station, carried aloft aboard an Atlas 5 rocket. | |
Experts: Mystery fireball was Russian satellitePeople from New Mexico to Montana saw the bright object break apart as it moved slowly northward across the night sky. Witnesses described it as three "rocks" with glowing red and orange streaks. | |
Video: MAVEN set to slide into orbit around MarsA NASA mission to Mars led by the University of Colorado Boulder is set to slide into orbit around the red planet this week after a 10-month, 442-million mile chase through the inner solar system. | |
Repaired Opportunity rover readies for 'Marathon Valley'With a newly cleared memory, it's time for Opportunity to resume the next stage of its long, long Martian drive. The next major goal for the long-lived rover is to go to Marathon Valley, a spot that (in images from orbit) appears to have clay minerals on site. Clay tends to form in the presence of water, so examining the region could provide more information about Mars' wet, ancient past. | |
Elon Musk gets fresh challenge with space contractWith a $2.6 billion contract for his firm SpaceX to build a spacecraft for carrying astronauts to the International Space Station, Elon Musk's star is on the rise again. | |
NASA releases IRIS footage of X-class flare (w/ Video)On Sept. 10, 2014, NASA's newest solar observatory, the Interface Region Imaging Spectrograph, or IRIS, mission joined other telescopes to witness an X-class flare – an example of one of the strongest solar flares—on the sun. Combing observations from more than one telescope helps create a much more complete picture of such events on our closest star. Watch the movie to see how the flare appears different through the eyes of IRIS than it does through NASA's Solar Dynamics Observatory. | |
Space: The final frontier... open to the publicHistorically, spaceflight has been reserved for the very healthy. Astronauts are selected for their ability to meet the highest physical and psychological standards to prepare them for any unknown challenges. However, with the advent of commercial spaceflight, average people can now fly for enjoyment. The aerospace medicine community has had very little information about what medical conditions or diseases should be considered particularly risky in the spaceflight environment, as most medical conditions have never been studied for risk in space—until now. | |
Amazon founder's firm to build new rocket enginesAmazon.com founder Jeff Bezos plans to build a rocket engine that would eventually replace the Russian mainstay used in many American unmanned launches. | |
Image: Rainbow aurora captured from space stationAuroras occur when particle radiation from the Sun hits Earth's upper atmosphere, making it glow in a greenish blue light. ESA astronaut Alexander Gerst has one of our planet's best views of this phenomenon, circling 400 km up on the Station. | |
Glowing galaxies in telescopic timelapseWe often speak of the discoveries and data flowing from astronomical observatories, which makes it easy to forget the cool factor. Think of it—huge telescopes are probing the universe under crystal-clear skies, because astronomers need the dark skies to get their work done. |
Medicine & Health news
Connection found between birth size and brain disorders(Medical Xpress)—A trio of researchers has found what appears to be a clear connection between birth size and weight, and the two brain disorders, autism and schizophrenia. In their paper published in Proceedings of the Royal Society B: Biological Sciences, Sean Byars and Jacobus Boomsma of the University of Copenhagen and Stephen Stearns with Yale University, describe how they found patterns in data from health records of almost 1.8 million people living in Denmark (born between 1978 and 2009) that connected the two types of brain disorders with birth weight and size. | |
Artificial sweeteners linked to abnormal glucose metabolismArtificial sweeteners, promoted as aids to weight loss and diabetes prevention, could actually hasten the development of glucose intolerance and metabolic disease; and they do it in a surprising way: by changing the composition and function of the gut microbiota – the substantial population of bacteria residing in our intestines. These findings, the results of experiments in mice and humans, were published today in Nature. Among other things, says Dr. Eran Elinav of the Weizmann Institute's Immunology Department, who led this research together with Prof. Eran Segal of Computer Science and Applied Mathematics Department, the widespread use of artificial sweeteners in drinks and food may be contributing to the obesity and diabetes epidemic that is sweeping much of the world. | |
Study links physical activity in older adults to brain white-matter integrityLike everything else in the body, the white-matter fibers that allow communication between brain regions also decline with age. In a new study, researchers found a strong association between the structural integrity of these white-matter tracts and an older person's level of daily activity – not just the degree to which the person engaged in moderate or vigorous exercise, but also whether he or she was sedentary the rest of the time. | |
Blood test could identify when cancer treatment has become detrimentalSome treatments for prostate cancer, while initially effective at controlling the disease, not only stop working over time but actually start driving tumour growth, a major new study shows. | |
Researchers use iPS cells to show statin effects on diseased boneSkeletal dysplasia is a group of rare diseases that afflict skeletal growth through abnormalities in bone and cartilage. Its onset hits at the fetal stage and is caused by genetic mutations. A mutation in the gene encoding fibroblast growth factor receptor 3 (FGFR3) has been associated with two types of skeletal dysplasia, thanatophoric dysplasia (TD), a skeletal dysplasia that cause serious respiratory problems at birth and is often lethal, and achondroplasia (ACH), which causes stunted growth and other complications throughout life. Several experimental treatments have been considered, but none are commercially available. | |
Babies learn words differently as they age, researcher findsResearch has shown that most 18-month-olds learn an average of two to five new words a day; however, little is known about how children process information to learn new words as they move through the preschool years. In a new study, a University of Missouri researcher has found that toddlers learn words differently as they age, and a limit exists as to how many words they can learn each day. These findings could help parents enhance their children's vocabularies and assist speech-language professionals in developing and refining interventions to help children with language delays. | |
In mice, vaccine stops urinary tract infections linked to cathetersThe most common type of hospital-associated infection may be preventable with a vaccine, new research in mice suggests. | |
World Alzheimer Report 2014 reveals persuasive evidence for dementia risk reductionThe World Alzheimer Report 2014 'Dementia and Risk Reduction: An analysis of protective and modifiable factors', released today, calls for dementia to be integrated into both global and national public health programmes alongside other major non communicable diseases (NCDs). | |
Sharks' skin has teeth in the fight against hospital superbugsTransmission of bacterial infections, including MRSA and MSSA could be curbed by coating hospital surfaces with microscopic bumps that mimic the scaly surface of shark skin, according to research published in the open access journal Antimicrobial Resistance and Infection Control. | |
Phthalates heighten risk for childhood asthmaResearchers at the Columbia Center for Children's Environmental Health at the Mailman School of Public Health are the first to demonstrate an association between childhood asthma and prenatal exposure to two phthalates used in a diverse array of household products. Results appear online in the journal Environmental Health Perspectives. | |

Identification of mutations causing lung cancer resistance leads to new treatment strategiesTwo mutations that cause lung cancer resistance to the investigational ALK inhibitor alectinib were identified, and this information may help design new treatment regimens for patients with ALK-positive lung cancer, according to a study published in Clinical Cancer Research, a journal of the American Association for Cancer Research. | |
Study offers clues to how breast implants may cause lymphoma(Medical Xpress)—There have been 71 known cases worldwide of a type of blood cancer called anaplastic large cell lymphoma (ALCL) that the researchers suggest were associated with the patient's breast implants. This means it is an extremely rare occurrence – for every three million breast implant procedures, the study estimates between one and six cases of ALCL. The ALCL was found to develop in patients, on average, 10 years after breast augmentation or reconstruction surgery. Studies have found no clear evidence of an increase in risk of any other type of cancer in women with breast implants. | |
Celebrity baby bumps found to affect pre-natal attachmentObsessing over celebrity baby bumps can have a negative impact on women's attachment to their babies during pregnancy and after birth, Victoria University of Wellington research has found. | |

Emotions in the brainThis year has been a busy one for biologist David Anderson, Caltech's Seymour Benzer Professor of Biology. In 2014 alone, Anderson's lab has reported finding neurons in the male fly brain that promote fighting and, in the mouse brain, identified a "seesaw" circuit that controls the transition between social and asocial behaviors, neurons that control aggressive behavior, a neural circuit that controls anxiety, and a network of cells that switches appetite on and off. | |
Improved risk identification will aid fertility preservation in young male cancer patients(Medical Xpress)—A study led by St. Jude Children's Research Hospital investigators has found the chemotherapy dose threshold below which male childhood cancer survivors are likely to have normal sperm production. The study appears in September 17 edition of the journal Lancet Oncology. | |
Study finds that neighbors improve well-being in middle and later life(Medical Xpress)—The old proverb says, "Good fences make good neighbors." But a new Rutgers study has found that having continuously low levels of contact with neighbors, or losing contact with them altogether, is associated with declining levels of psychological well-being in middle and later life. | |
What's in your porcini packet? You may find a new species ... or threeMycologists – scientists who study fungi – estimate there are up to five million species of fungi on Earth. Of these, only about 2%, or 100,000 species, have been formally described. So where are the other 98% of fungi hiding? | |
Here's to wine, chocolate and a long, healthy lifeJeanne Calment, who died in 1997 at the age of 122, remains the oldest person on record. One might assume that she led a faultless, healthy lifestyle. Not at all.

Five genes to predict colorectal cancer relapsesResearchers at the Catalan Institute of Oncology-Bellvitge Biomedical Research Institute (ICO-IDIBELL), led by David Garcia-Molleví have identified 5 genes differentially expressed in normal accompanying cells in colorectal tumors. Analysis of these genes could be used to classify colorectal tumors, predict the evolution of the patient and thus take appropriate clinical decisions to prevent relapses. | |
Protein variant may boost cardiovascular risk by hindering blood vessel repairResearchers at UT Southwestern Medical Center have found that the most common variant of the circulating protein apolipoprotein E, called apoE3, helps repair the lining of blood vessels. Individuals with another variant, called apoE4, do not get the benefit of this repair, putting them at higher risk for cardiovascular disease. | |
Researchers examine role of hormone in response to ovarian cancer treatmentThe work comes out of the molecular therapeutic laboratory directed by Richard G.

Research shows that magnetic resonance helps to detect and quantify fat in liverObesity and overweight affect more than half of the population in our Community. Excess weight causes important alterations in the organism, one of which affects liver function. Fat accumulates in the liver producing hepatic steatosis which, in certain circumstances, causes inflammation, fibrosis and finally, cirrhosis. To date, the most reliable method for determining hepatic fat has been hepatic biopsy. Imaging techniques such as abdominal ecography detect it but are less precise for determining the quantity of fat. | |
New MRI technique helps clinicians better predict outcomes following mild traumatic brain injuryDiffusion Tensor Imaging (DTI), a specialized magnetic resonance imaging (MRI) technique that detects microstructural changes in brain tissue, can help physicians better predict the likelihood for poor clinical outcomes following mild traumatic brain injury compared to conventional imaging techniques such as computed tomography (CT), according to a new study published in Journal of Neurotrauma. | |

US health system not properly designed to meet needs of patients nearing end of life, says IOMThe U.S. health care system is not properly designed to meet the needs of patients nearing the end of life and those of their families, and major changes to the system are necessary, says a new report from the Institute of Medicine. The 21-member committee that wrote the report envisioned an approach to end-of-life care that integrates traditional medical care and social services and that is high-quality, affordable, and sustainable. The committee called for more "advance care planning" for end-of-life by individuals, for improved training and credentialing for clinicians, and for federal and state governments and private sectors to provide incentives to patients and clinicians to discuss issues, values, preferences, and appropriate services and care. | |
Targeted radiation, drug therapy combo less toxic for recurrent head, neck cancersPatients with a recurrence of head and neck cancer who have previously received radiation treatment can be treated more quickly, safely and with fewer side effects with high doses of targeted radiation known as Stereotactic Body Radiation Therapy (SBRT) in combination with a drug that also carefully targets cancerous tumors. These findings from a UPMC CancerCenter study were presented today at the American Society of Radiation Oncology (ASTRO) annual meeting in San Francisco. | |
