Astronomy & Space news

	US spacecraft enters Mars orbit, India probe next (Update) NASA's Maven spacecraft entered orbit around Mars for an unprecedented study of the red planet's atmosphere following a 442 million-mile (710 million-kilometer) journey that began nearly a year ago.
	Sky survey of gamma ray sources reveals galactic energy bubbles Yesterday I talked about the Fermi gamma ray telescope, and how it allowed us to make much more precise observations of gamma rays in the universe. Part of the purpose of the Fermi telescope is to observe gamma ray bursts, but its broader purpose is to make a sky survey of gamma ray sources in the universe. Already it has found something quite interesting.
	Finding hints of gravitational waves in the stars Scientists have shown how gravitational waves—invisible ripples in the fabric of space and time that propagate through the universe—might be "seen" by looking at the stars. The new model proposes that a star that oscillates at the same frequency as a gravitational wave will absorb energy from that wave and brighten, an overlooked prediction of Einstein's 1916 theory of general relativity. The study, which was published today in the Monthly Notices of the Royal Astronomical Society: Letters, contradicts previous assumptions about the behavior of gravitational waves.
	Infant solar system shows signs of windy weather Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have observed what may be the first-ever signs of windy weather around a T Tauri star, an infant analog of our own Sun. This may help explain why some T Tauri stars have disks that glow weirdly in infrared light while others shine in a more expected fashion.
	An anomaly in satellite flybys confounds scientists When space probes, such as Rosetta and Cassini, fly over certain planets and moons in order to gain momentum and travel long distances, their speed changes slightly for an unknown reason. A Spanish researcher has now analysed whether or not a hypothetical gravitomagnetic field could have an influence. However, other factors such as solar radiation, tides, or even relativistic effects or dark matter could be behind this mystery.
	What causes the diffraction spikes in images of stars? When stars are portrayed in media, they are often shown with long spikes emanating from them. Perhaps the most common example is that of the "star of Bethlehem" which, according to the story, led the wise men to baby Jesus. Of course when we look at stars in the night sky, we don't see any such spikes. Stars twinkle due to atmospheric disturbances, but that's about it. In photographs, however, bright stars often have such long spikes. So what causes them? It all has to do with an interesting bit of optics.
	The frequency of high-energy gamma ray bursts In the 1960s a series of satellites were built as part of Project Vela.  Project Vela was intended to detect violations of the 1963 ban on above ground testing of nuclear weapons.  The Vela satellites were designed to detect bursts of gamma rays, which are high energy electromagnetic waves (light) produced by radioactive decay.  If any nuclear weapon was detonated in space, the resulting radioactive decay would release a large amount of gamma rays which would be detected by the Vela satellites.
	How gamma ray telescopes work Yesterday I talked about the detection of gamma ray bursts, intense blasts of gamma rays that occasionally appear in distant galaxies. Gamma ray bursts were only detected when gamma ray satellites were put into orbit in the 1960s. This is because gamma rays are absorbed by our atmosphere. Even then, the detectors were relatively primitive and couldn't determine the direction of the bursts. Instead, multiple satellites were used to triangulate the location of these bursts. Since then, gamma ray astronomy has gotten much more sophisticated.
	Experts and audience contest Pluto's 'dwarf planet' status Could the stars be aligned for Pluto to reassume its place in the solar system? The International Astronomical Union (IAU) voted in 2006 to demote Pluto from planetary status. But after an hourlong debate Thursday night between planetary science experts on what constitutes a planet, an audience packed into Phillips Auditorium at the Harvard-Smithsonian Center for Astrophysics (CfA) voted to restore it to its former rank.
	University launches world's first photographs taken with telescope made by 3D printing The University of Sheffield has released the very first photos of space ever taken with a telescope that has been made using a 3D printer.
	Living on the edge: Rosetta's lander philae is set to take the plunge This is a very exciting time for space science in general and for the Rosetta spacecraft in particular. A little more than a month after arriving at comet 7P/Churyumov-Gerasimenko, Rosetta has mapped its surface well enough to help scientists choose a location to set down Philae, the first-ever comet lander. Or, at least, try to. Here to tell us more about the recent mapping of comet 7P/Churyumov-Gerasimenko, the announcement Philae's landing site, and what comes next for the Rosetta spacecraft is Dr. Claudia Alexander of the Rosetta mission.
	NASA launches RapidScat wind watcher to Space Station A new NASA mission that will boost global monitoring of ocean winds for improved weather forecasting and climate studies is among about 5,000 pounds (2,270 kilograms) of NASA science investigations and cargo now on their way to the International Space Station aboard SpaceX's Dragon spacecraft. The cargo ship launched on the company's Falcon 9 rocket from Space Launch Complex-40 at Cape Canaveral Air Force Station in Florida at 10:52 p.m. PDT Saturday, Sept. 20 (1:52 a.m. EDT Sunday, Sept. 21).
	Explainer: What makes the spring equinox? It's the time of the equinox or more specifically the spring equinox for us in the southern hemisphere.
	Breezy science, plant studies and more head to space station on SpaceX-4 Imagine a dragon flying through the heavens on mighty, outstretched wings. The majestic beast knows the currents of winds and how to harness their power as it soars above the clouds. SpaceX's real Dragon- the company's spacecraft that transports supplies and science to the International Space Station (ISS) - will deliver, and later return, new technology, biology and biotechnology and Earth and space science research to the orbiting outpost.
Gravitational waves according to Planck Scientists of the Planck collaboration, and in particular the Trieste team, have conducted a series of in-depth checks on the discovery recently publicized by the Antarctic Observatory, which announced last spring that it had detected some direct effects of gravitational waves on cosmic microwave background radiation, a potentially groundbreaking discovery in the field of cosmology. Analysis of the Planck satellite data demonstrates that the effect of contaminating sources, such as gases from our galaxy, cannot be ruled out.
SpaceX breaks ground on Texas rocket launch site SpaceX founder Elon Musk says his company expects to spend $100 million in South Texas over the next three to four years on the first commercial orbital spaceport.
	NASA launches new citizen science website; opens challenge to participate in future Mars missions NASA announced Saturday the opening of registration for its Mars Balance Mass Challenge and the launch of its new website, NASA Solve, at the World Maker Faire in New York.

Medicine & Health news

	Study reveals how gene expression affects facial expressions A person's face is the first thing that others see, and much remains unknown about how it forms—or malforms—during early development. Recently, Chong Pyo Choe, a senior postdoctoral fellow working in the lab of USC stem cell researcher Gage Crump, has begun to unwind these mysteries.
	Neuroscientists challenge long-held understanding of the sense of touch Different types of nerves and skin receptors work in concert to produce sensations of touch, University of Chicago neuroscientists argue in a review article published Sept. 22, 2014, in the journal Trends in Neurosciences. Their assertion challenges a long-held principle in the field—that separate groups of nerves and receptors are responsible for distinct components of touch, like texture or shape. They hope to change the way somatosensory neuroscience is taught and how the science of touch is studied.
	Brainwave test could improve autism diagnosis and classification A new study by researchers at Albert Einstein College of Medicine of Yeshiva University suggests that measuring how fast the brain responds to sights and sounds could help in objectively classifying people on the autism spectrum and may help diagnose the condition earlier. The paper was published today in the online edition of the Journal of Autism and Developmental Disabilities.
	The fine line between breast cancer and normal tissues Up to 40 percent of patients undergoing breast cancer surgery require additional operations because surgeons may fail to remove all the cancerous tissue in the initial operation. However, researchers at Brigham and Women's Hospital (BWH) have successfully tested a tool they developed that will help surgeons better distinguish cancerous breast tissue from normal tissue, thereby decreasing the chances for repeat operations.
	Immune response turned up, not down, by flu during pregnancy, study finds Pregnant women have an unusually strong immune response to influenza, an unexpected finding that may explain why they get sicker from the flu than other healthy adults, new research from the Stanford University School of Medicine and Lucile Packard Children's Hospital Stanford has found.
	Platelets modulate clotting behavior by 'feeling' their surroundings Platelets, the tiny cell fragments whose job it is to stop bleeding, are very simple. They don't have a cell nucleus. But they can "feel" the physical environment around them, researchers at Emory and Georgia Tech have discovered.
	Using mathematical theory and software tools, team studies why a variable heart rate is a sign of health and fitness Although the heart beats out a very familiar "lub-dub" pattern that speeds up or slows down as our activity increases or decreases, the pattern itself isn't as regular as you might think. In fact, the amount of time between heartbeats can vary even at a "constant" heart rate—and that variability, doctors have found, is a good thing.
	Old drug may be key to new antibiotics McMaster scientists have found that an anticonvulsant drug may help in developing a new class of antibiotics.
	Dry roasting could help trigger peanut allergy Dry roasted peanuts are more likely to trigger an allergy to peanuts than raw peanuts, suggests an Oxford University study involving mice.
E-cigarettes unhelpful in smoking cessation among cancer patients In a new study of cancer patients who smoke, those using e-cigarettes (in addition to traditional cigarettes) were more nicotine dependent and equally or less likely to have quit smoking traditional cigarettes than non-users. Published early online in Cancer, a peer-reviewed journal of the American Cancer Society, the findings raise doubts about the potential benefits of e-cigarettes for helping cancer patients give up smoking.

Narrow focus on physical activity could be ruining kids' playtime While public health authorities focus on the physical activity benefits of active play, a new study from the University of Montreal reveals that for children, playing has no goal – it is an end in itself, an activity that is fun, done alone or with friends, and it represents "an opportunity to experience excitement or pleasure, but also to combat boredom, sadness, fear, or loneliness."
Researchers study impact of smoking ban in homeless shelter Instituting a partial smoking ban at a homeless shelter can lead to a reduction in expired carbon monoxide levels, an indicator of exposure to cigarette smoke, and may have positive effects on shelter residents' health, according to new research. The University of Texas Health Science Center at Houston (UTHealth) released the study results last week in the journal Addictive Behaviors.
