![]() | Astronomers reveal insights into the nature of a distant ultraviolet-bright starA team of astronomers led by William Dixon of the Space Telescope Science Institute in Baltimore, Maryland, has presented new spectral analysis of the ultraviolet-bright star Y453. The study, presented Aug. 3 in a paper published on arXiv.org, reveals insights about the star's physical parameters, chemical composition and its evolution. |
![]() | SpaceX to launch super-computer to spaceSpaceX is poised to launch an unmanned cargo ship toward the International Space Station Monday, including a super-computer that could direct astronauts on future deep-space missions. |
![]() | TRAPPIST-1 is older than our solar systemIf we want to know more about whether life could survive on a planet outside our solar system, it's important to know the age of its star. Young stars have frequent releases of high-energy radiation called flares that can zap their planets' surfaces. If the planets are newly formed, their orbits may also be unstable. On the other hand, planets orbiting older stars have survived the spate of youthful flares, but have also been exposed to the ravages of stellar radiation for a longer period of time. |
![]() | Properties of a massive galaxy 800 million years after the Big BangSearches for the most distant galaxies have now probed earlier than the first billion years in the history of the universe, early enough to start seeing the primary effects of the first stars: the reionization of neutral atoms. |
![]() | Image: A partial solar eclipse seen from spaceThanks to a quirk of our cosmos, the moon's average distance from Earth is just right for it to appear as the same size in the sky as the significantly larger sun. Once in a while the moon slides directly between Earth and the sun such that it appears to cover our star completely, temporarily blocking out its light and creating a total solar eclipse for those along the narrow path cast by the moon's shadow. |
![]() | Hubble displays a dwarf spiral galaxyThe subject of this NASA/ESA Hubble Space Telescope image is a dwarf galaxy named NGC 5949. Thanks to its proximity to Earth—it sits at a distance of around 44 million light-years from us, placing it within the Milky Way's cosmic neighborhood—NGC 5949 is a perfect target for astronomers to study dwarf galaxies. |
![]() | Asteroid Apophis has one in 100,000 chance of hitting Earth, expert estimatesThe huge, nearly 400-meter-wide asteroid Apophis is still on a list of hazardous near-Earth objects (NEOs), regarded as a potential threat to the planet. However, new calculations made by NASA's Jet Propulsion Laboratory (JPL) show that Apophis' odds of Earth impact are lower than previously estimated. |
![]() | Stars orbiting supermassive black hole show Einstein was right againAt the center of our galaxy, roughly 26,000 light years from Earth, lies the supermassive black hole (SMBH) known as Sagittarius A*. Measuring 44 million km across, this object is roughly 4 million times as massive as our Sun and exerts a tremendous gravitational pull. Since astronomers cannot detect black holes directly, its existence has been determined largely from the effect it has on the small group of stars orbiting it. |
![]() | SpaceX launches experiments, ice cream to space stationA SpaceX capsule rocketed to the International Space Station on Monday, carrying tons of science research, plus ice cream. |
![]() | Get them while they're young: Astronomers catch exploding supernova early (Update)For the first time, astronomers have observed a cosmic event in great detail that they only had glimpses of before: a supernova and its explosive ejecta slamming into a nearby companion star. The discovery was made possible by a specialized survey taking advantage of recent advances in linking telescopes across the globe into a robotic network. |
![]() | Tidally locked exoplanets may be more common than previously thoughtMany exoplanets to be found by coming high-powered telescopes will probably be tidally locked—with one side permanently facing their host star—according to new research by astronomer Rory Barnes of the University of Washington. |
![]() | More than spectacle: Eclipses create science and so can youThe sun is about to spill some of its secrets, maybe even reveal a few hidden truths of the cosmos. And you can get in on the act next week if you are in the right place for the best solar eclipse in the U.S. in nearly a century. |
Eclipse of reason—why do people disbelieve scientists?If you've been paying attention, you know that on Aug. 21, we're in for a special cosmic treat: the Great American Eclipse of 2017. | |
![]() | NASA Reignites Program for Nuclear Thermal RocketsIn its pursuit of missions that will take us back to the moon, to Mars, and beyond, NASA has been exploring a number of next-generation propulsion concepts. Whereas existing concepts have their advantages – chemical rockets have high energy density and ion engines are very fuel-efficient – our hopes for the future hinge on us finding alternatives that combine efficiency and power. |
![]() | New 3-D simulations show how galactic centers cool their jetsSome of the most extreme outbursts observed in the universe are the mysterious jets of energy and matter beaming from the center of galaxies at nearly the speed of light. These narrow jets, which typically form in opposing pairs are believed to be associated with supermassive black holes and other exotic objects, though the mechanisms that drive and dissipate them are not well understood. |
![]() | Studying the Sun's atmosphere with the total solar eclipse of 2017A total solar eclipse happens somewhere on Earth about once every 18 months. But because Earth's surface is mostly ocean, most eclipses are visible over land for only a short time, if at all. The total solar eclipse of Aug. 21, 2017, is different - its path stretches over land for nearly 90 minutes, giving scientists an unprecedented opportunity to make scientific measurements from the ground. |

![]() | Discovery of new prostate cancer biomarkers could improve precision therapyMayo Clinic researchers have identified a new cause of treatment resistance in prostate cancer. Their discovery also suggests ways to improve prostate cancer therapy. The findings appear in Nature Medicine. In the publication, the authors explain the role of mutations within the SPOP gene on the development of resistance to one class of drugs. SPOP mutations are the most frequent genetic changes seen in primary prostate cancer. These mutations play a central role in the development of resistance to drugs called BET-inhibitors. |
![]() | Change in protein production essential to muscle functionResearchers at Baylor College of Medicine have shed light on the process that guides the maturation of newborn muscles into adult, fully functional organs. In mice, they determined that a group of genes involved in calcium handling undergoes a highly-regulated process called alternative splicing that changes the type of protein the genes produce as muscles transition from newborn to adult. These protein changes are essential for normal adult muscle function and, when disturbed, lead to muscle disorders such as myotonic dystrophy, the second most common cause of muscular dystrophy, and numerous other muscle disorders that affect tens of thousands of individuals in the U.S. The study appears in eLife. |
![]() | Granulins are brain treasure, not trashEmory University School of Medicine researchers have developed tools that enable them to detect small proteins called granulins for the first time inside cells. Granulins are of interest to neuroscientists because mutations in the granulin gene cause frontotemporal dementia (FTD). However, the functions of granulins were previously unclear. |

'Smiley' emojis in formal workplace e-mails could create frowns, study saysA smiley face emoji and similar emoticons included in work-related e-mails may not create a positive impression and could even undermine information sharing, according to a new study by researchers at Ben-Gurion University of the Negev (BGU). | |
![]() | New blood test may transform the way cancer is monitored and treatedStanford University scientists have described a new type of test that can detect genetic mutations in minute amounts of DNA released from cancer cells into the blood. The test, which is called single color digital PCR, requires only a fraction of a tube of blood and can detect as few as three mutation-bearing molecules in a single reaction. According to the report in The Journal of Molecular Diagnostics, this highly sensitive test has the potential to be personalized to recognize mutations unique to any individual cancer. |
Cognitive abilities seem to reinforce each other in adolescenceOne of the most striking findings in psychology is that almost all cognitive abilities are positively related - on average, people who are better at a skill like reasoning are generally also better at a skill like vocabulary. This fact allows scientists and educational practitioners to summarize people's skills on a wide range of domains as one factor - often called 'g', for 'general intelligence'. Despite this, the mechanisms underlying 'g' and its development remain somewhat mysterious. | |

Menopausal status may better predict blood vessel health in women than fitness levelHigh physical fitness is known to be related to enhanced blood vessel dilation and blood flow (endothelial function) in aging men. However, for women, endothelial function and the effect of exercise may be related more to menopausal status than fitness. Researchers from the University of Massachusetts Amherst will present their findings today at the Cardiovascular Aging: New Frontiers and Old Friends conference in Westminster, Colo. | |
![]() | Map of oncogenic dependencies for the design of personalized therapeutic approachesBeing able to predict the resistance or sensitivity of a tumour cell to a drug is a key success factor of cancer precision therapy. But such a prediction is made difficult by the fact that genetic alterations in tumours change dynamically over time and are often interdependent, following a pattern that is poorly understood. A recent study led by researchers at the SIB Swiss Institute of Bioinformatics, University of Lausanne and EPFL provides a promising framework to anticipate drug resistance in cancer by predicting the co-occurrence of about 500 known tumour alterations, as well as their response to over 200 common cancer drugs. The research, published in Cancer Cell, showed that while some co-occurrences between genomic alterations confer a resistance to tumour cells against particular drugs, they also make them sensitive to other unexpected drugs. |
Characteristics of international drug regulatory regimesThe regulatory requirements for the approval of new drugs vary greatly internationally in regards to the resources allocated to the authorities, the evaluation periods for approval and the fees for the pharmaceutical companies.

![]() | Genetic mechanism prevents kidney injury after severe dehydrationMillions of people die every year from dehydration as a result of exposure and illness. In humans, even the most minor dehydration can compromise the kidneys causing lifelong, irreparable issues or even death. However, some animals living in desert environments are able to survive both acute and chronic dehydration. While these animals, like cactus mice, have evolved over time to deal with environmental stressors like dehydration, researchers at the University of New Hampshire have found it's not the physical makeup that is helping them survive, but rather their genetic makeup. |

![]() | High use of electronic cigarettes seen in 8th-9th graders in OregonA study at Oregon Research Institute (ORI) shows that rates of electronic cigarette (e-cigarette) use among Oregon 8th and 9th graders is higher than seen in national samples, and that e-cigarette use is closely linked with use of marijuana and other tobacco products. Led by ORI scientist Erika Westling, Ph.D., study investigators examined e-cigarette prevalence rates in 8th graders and tracked early usage patterns from 8th grade through 9th grade, the first year of high school. Westling and her team also examined gender, ethnicity, and the use of other substances. Study results were recently published in the June 2017 issue of the Journal of Adolescent Health. |
Doctors trained at lowest-ranked medical schools prescribe more opioidsPhysicians trained at the United States' lowest-ranked medical schools write more opioid prescriptions than physicians trained at the highest-ranked schools, according to a study by Princeton University.

![]() | Most people expect physicians and nurses to protect them from harm in the hospitalHospitals are not off limits to tragic shooting events, and with these incidents on the rise in public places, more than half of the general public expects that physicians and nurses will protect them from harm if an active shooter event erupts while they're in the hospital. Likewise, more than half of health care professionals believe they have a special duty to protect patients under these circumstances. But the two groups differ about the inherent safety of hospitals, with most people viewing them as safe havens, while health care professionals are more likely to view the hospital as a potentially risky setting for an active shooter event. These beliefs are among key findings from a national survey conducted in March 2017 by the Hartford Consensus. The results are published online as an "article in press" on the website of the Journal of the American College of Surgeons in advance of print. |

Virulence factor made by influenza virus is potential target for vaccine drug developmentA new study describes how NS1, a protein produced by influenza A viruses, suppresses the body's immune responses to viral infection. Researchers present the potential to develop a live attenuated vaccine based on an engineered influenza A virus lacking NS1 and to design antiviral drugs that target NS1. The study is published in Journal of Interferon & Cytokine Research (JICR). | |
Working memory may compensate for lack of attentionA study in eNeuro shows that, when remembering a sequence of events, the brain focuses on the event paid the least attention, rather than replaying the events in the order they occurred. This finding suggests that attention during the initial encoding of a memory influences how information is manipulated in working memory. | |
![]() | Running rats remember betterYoung rats with access to a running wheel show improved memory later in life and increased activity of neurons generated in adulthood, finds a study published in eNeuro. The results raise the possibility that exercise early in life may help to protect against age-related cognitive decline. |

![]() | Cancer-fighting T cells are smarter, stronger than experts thoughtScientists studying the body's cancer-fighting T cells have a serious problem: When they culture them in the lab, the T cells sit around at equilibrium, waiting to bump into cancerous cells. But that's not how they operate inside the body. There, they are motorized little bloodhounds, actively seeking out infected cells. |
![]() | The origin of the chloroplastA new study, led by the University of Bristol, has shed new light on the origin, timing and habitat in which the chloroplast first evolved. |
![]() | Viruses up their game in arms race with immune systemIn a classic example of the evolutionary arms race between a host and a pathogen, the myxoma virus—introduced to control the rabbit population in Australia in 1950—has developed a novel and deadly ability to suppress the immune response of its host rabbits. New research shows that viruses collected in the 1990s are much more effective at shutting down the immune systems of rabbits that have never been exposed to the virus than are viruses from the 1950s. |
![]() | Researchers describe neural mechanisms for gregariousness and monogamy in zebra finchesHow do gregarious songbirds such as zebra finches, where both males and females live in close proximity and where females may be attracted by the songs of many potential suitors, sustain monogamy? A new study appearing in eLife sheds light on how males have evolved a high tolerance to birdsong while females have evolved a high selectivity to these songs. |

![]() | Fighting ivory trafficking with forensic scienceTwo weeks ago, Kevin Uno was on a field expedition in Kenya when he got a message he'd been hoping for: the NY Department of Environmental Conservation had officially approved his request to sample some ivory that had been confiscated from retail stores in the U.S. The Lamont-Doherty Earth Observatory geochemist and his colleague, University of Washington research professor Samuel Wasser, use radiocarbon dating and DNA testing to determine when and where an elephant was killed; sampling this recently seized ivory would be an opportunity for them to find out whether it was recently harvested, and help law enforcement target the poachers responsible. |
![]() | Why aren't we more outraged about eating chicken?Like a B-movie for a post-Brexit era, consumers in Britain may soon be unwillingly cast in the 2019 blockbuster, Attack of the Chlorine Chickens. If news headlines are to be believed, flocks of toxic fowl are waiting to storm Britain's shores like mini featherless zombies as part of a US-UK trade deal. |
![]() | Cows in Antarctica? How one expedition milked them for all their worthDomestic animals are rarely associated with Antarctica. However, before non-native species (bar humans) were excluded from the continent in the 1990s, many travelled to the far south. These animals included not only the obvious sledge dogs, but also ponies, sheep, pigs, hamsters, hedgehogs and a goat. Perhaps the most curious case occurred in 1933, when US Admiral Richard E. Byrd's second Antarctic expedition took with it three Guernsey cows. |
