	New chemical analysis of ancient Martian meteorite provides clues to planet's history of habitability A new analysis of a Martian rock that meteorite hunters plucked from an Antarctic ice field 30 years ago this month reveals a record of the planet's climate billions of years ago, back when water likely washed across its surface and any life that ever formed there might have emerged.
	Image: Hubble sweeps a messy star factory This sprinkle of cosmic glitter is a blue compact dwarf galaxy known as Markarian 209. Galaxies of this type are blue-hued, compact in size, gas-rich, and low in heavy elements. They are often used by astronomers to study star formation, as their conditions are similar to those thought to exist in the early Universe.
	Gecko grippers get a microgravity test flight (w/ Video) There are no garbage trucks equipped to leave the atmosphere and pick up debris floating around the Earth. But what if we could send a robot to do the job?
	The Milky Way's new neighbour The Milky Way, the galaxy we live in, is part of a cluster of more than 50 galaxies that make up the 'Local Group', a collection that includes the famous Andromeda galaxy and many other far smaller objects. Now a Russian-American team have added to the canon, finding a tiny and isolated dwarf galaxy almost 7 million light years away. Their results appear in Monthly Notices of the Royal Astronomical Society.
	Ultra-luminous X-ray sources in starburst galaxies Ultra-luminous X-ray sources (ULXs) are point sources in the sky that are so bright in X-rays that each emits more radiation than a million suns emit at all wavelengths. ULXs are rare. Most galaxies (including our own Milky Way) have none, and those galaxies that do host a ULX usually contain only one. ULXs are also mysterious objects. They can't be normal stars because their huge luminosities should then tear them apart. Most astronomers think that ULXs are black holes more than about ten solar masses in size (so-called intermediate mass black holes) that are accreting matter onto a surrounding disk and emitting X-rays. Bright X-ray emission is not unusual - the nuclei of galaxies also are bright X-ray emitters - but they are super-massive black holes, while ULXs are neither super-massive nor located in galactic nuclei.
	When a bright light fades Astronomer Charles Telesco is primarily interested in the creation of planets and stars. So, when the University of Florida's giant telescope was pointed at a star undergoing a magnificent and explosive death, Telesco, a UF professor, didn't immediately appreciate what a rare and valuable find he had.
	Astrophysicists offer new research, tool for identifying habitable zones Research by a University of Texas at Arlington astrophysicist sheds greater light on S-type and P-type binary stars and forms the basis for BinHab, a new online tool that can be used to calculate the regions of binary systems favorable for life, commonly known as habitable zones.
	Funding challenges for Orion and SLS The Government Accountability Office (GAO) is the audit, evaluation, and investigative arm of Congress, which exists to support Congress in meeting its constitutional responsibilities and to help improve the performance and accountability of the federal government. On Dec. 10 the Space Subcommittee of the House Science, Space and Technology Committee held a hearing on the progress of the nation's next generation deep space exploration vehicle and heavy lift rocket. GAO Director of Acquisition and Sourcing Management Christina Chaplain testified on the progress of the Space Launch System (SLS) and Orion crew vehicle, which are being developed for deep space human missions that will take astronauts to the Moon and Mars. In an interview with astrowatch.net Chaplain discusses challenges that NASA's human space exploration programs have to face in order to successfully send U.S. astronauts beyond Earth.
	Image: Horsehead nebula viewed in infrared Sometimes a horse of a different color hardly seems to be a horse at all, as, for example, in this newly released image from NASA's Spitzer Space Telescope. The famous Horsehead nebula makes a ghostly appearance on the far right side of the image, but is almost unrecognizable in this infrared view. In visible-light images, the nebula has a distinctively dark and dusty horse-shaped silhouette, but when viewed in infrared light, dust becomes transparent and the nebula appears as a wispy arc.
	Four Galileo satellites at ESA test centre ESA engineers unwrapped a welcome Christmas present: the latest Galileo satellite. The navigation satellite will undergo a full checkout in Europe's largest satellite test facility to prove its readiness for space.
	Water fleas prepared for trip to space Local 'Daphnia' waterfleas are currently being prepared by scientists at the University of Birmingham for their trip to the International Space Station (ISS), where they will be observed by astronauts.
	NASA's first Orion crew module arrives safely back at Kennedy Space Center After a history making journey of more than 66,000 miles through space, ocean splash down and over 2000 mile cross country journey through the back woods of America, NASA's pathfinding Orion crew capsule has returned to its home base at the Kennedy Space Center in Florida.
	The worst trip around the world As you celebrate the end of the year in the warmth of your home, spare a thought for the organisms riding with a third-class ticket on the International Space Station – bolted to the outside with no protection against open space.
	Scientists 'map' water vapor in Martian atmosphere Russian scientists from the Space Research Institute of the Russian Academy of Sciences and the Moscow Institute of Physics and Technology (MIPT), together with their French and American colleagues, have created a 'map' of the distribution of water vapour in Mars' atmosphere. Their research includes observations of seasonal variations in atmospheric concentrations using data collected over ten years by the Russian-French SPICAM spectrometer aboard the Mars Express orbiter. This is the longest period of observation and provides the largest volume of data about water vapour on Mars.
	Image: Multicoloured view of supernova remnant Most celestial events unfold over thousands of years or more, making it impossible to follow their evolution on human timescales. Supernovas are notable exceptions, the powerful stellar explosions that make stars as bright as an entire galaxy for several days.
	Holiday lights on the Sun: SDO imagery of a significant solar flare The sun emitted a significant solar flare, peaking at 7:28 p.m. EST on Dec. 19, 2014.

Medicine & Health news

	Light-emitting e-readers detrimentally shift circadian clock, study shows You may think your e-reader is helping you get to sleep at night, but it might actually be harming your quality of sleep, according to researchers. Exposure to light during evening and early nighttime hours suppresses release of the sleep-facilitating hormone melatonin and shifts the circadian clock, making it harder to fall asleep at bedtime.
	Team finds new genetic anomalies in lung cancer Developing effective treatments for lung cancer has been challenging, in part because so many genetic mutations play a role in the disease.
	New research suggests an existing drug, riluzole, may prevent foggy 'old age' brain Forgetfulness, it turns out, is all in the head. Scientists have shown that fading memory and clouding judgment, the type that comes with advancing age, show up as lost and altered connections between neurons in the brain. But new experiments suggest an existing drug, known as riluzole and already on the market as a treatment for ALS, may help prevent these changes.
Echolocation acts as substitute sense for blind people Recent research carried out by scientists at Heriot-Watt University has demonstrated that human echolocation operates as a viable 'sense', working in tandem with other senses to deliver information to people with visual impairment.
	Diverse autism mutations lead to different disease outcomes People with autism have a wide range of symptoms, with no two people sharing the exact type and severity of behaviors. Now a large-scale analysis of hundreds of patients and nearly 1000 genes has started to uncover how diversity among traits can be traced to differences in patients' genetic mutations. The study, conducted by researchers at Columbia University Medical Center, was published Dec. 22 in the journal Nature Neuroscience.
	Flashes of light help researchers to both 'read' and 'write' brain signals University College London researchers have developed an innovative way to understand how the brain works by using flashes of light, allowing them to both 'read' and 'write' brain signals.
	Scientists uncover new, fundamental mechanism for how resveratrol provides health benefits Scientists at The Scripps Research Institute (TSRI) have found that resveratrol, the red-wine ingredient once touted as an elixir of youth, powerfully activates an evolutionarily ancient stress response in human cells. The finding should dispel much of the mystery and controversy about how resveratrol really works.
	Suppressing a protein reduces cancer spread in mice Scientists have found that decreasing the levels of or blocking a specific protein commonly found in humans and many other animals allowed them to slow the spread of two different kinds of cancer to the lungs of mice. The research indicates that when the protein becomes dysregulated it helps pave the way for cancers to spread and suggests that addressing such dysregulation is a lead worth pursuing in fighting metastasis.
	New technology makes tissues, someday maybe organs A new instrument could someday build replacement human organs the way electronics are assembled today: with precise picking and placing of parts.
	Fast-food consumption linked to lower test score gains in 8th graders The amount of fast food children eat may be linked to how well they do in school, a new nationwide study suggests.
	New non-invasive method can detect Alzheimer's disease early No methods currently exist for the early detection of Alzheimer's disease, which affects one out of nine people over the age of 65. Now, an interdisciplinary team of Northwestern University scientists and engineers has developed a noninvasive MRI approach that can detect the disease in a living animal. And it can do so at the earliest stages of the disease, well before typical Alzheimer's symptoms appear.
	New cell marking technique to help understand how our brain works Scientists from the University of Southampton have developed a new technique to mark individual brain cells to help improve our understanding of how the brain works.
	Fragile bones of modern humans result from reduced physical activity New research across thousands of years of human evolution shows that our skeletons have become much lighter and more fragile since the invention of agriculture - a result of our increasingly sedentary lifestyles as we shifted from foraging to farming.
	Team finds drug that helps Huntington's disease-afflicted mice—and their offspring Famine, drug abuse and even stress can "silence" certain genes, causing health problems in generations to come. Now scientists are wondering—could therapies that change gene expression in parents help their children?
	Blocking Notch pathway leads to new route to hair cell regeneration to restore hearing Sensory hair cell loss is the major cause of hearing loss and balance disorders. The postnatal mammalian inner ear harbors progenitor cells which have the potential for hair cell regeneration and hearing recovery, but the mechanisms that control their proliferation and hair cell regeneration are yet to be determined. Now scientists from the Eaton-Peabody Laboratories at Massachusetts Eye and Ear/Harvard Medical School and Fudan University, Shanghai, China, have shown that blocking the Notch pathway, known to control the elaborate hair cell distribution in the inner ear, plays an essential role that determines cochlear progenitor cell proliferation capacity. Their research was published today in PNAS Early Edition.
	Fear of terrorism increases resting heart rate and risk of death A new study of over 17,000 Israelis has found that long-term exposure to the threat of terrorism can elevate people's resting heart rates and increase their risk of dying. This is the first statistics-based study, and the largest of its kind, which indicates that fear induced by consistent exposure to the threat of terror can lead to negative health consequences and increase the risk of mortality.
	Study: Extra income boosts health of elderly in poor countries Boosting the incomes of poor, elderly residents in developing countries can significantly improve their health and well-being, particularly in lung function and memory, a new study released Monday shows.
Skin patch could help heal, prevent diabetic ulcers, study finds Researchers at the Stanford University School of Medicine say they have developed a safe and effective skin patch to deliver a drug that enhances the healing of diabetes-related ulcers. The patch, which they tested in mice, may also serve as a way to prevent ulcer formation.
Consumer purchases of cakes, cookies, pies have decreased by 24 percent Ready-to-eat grain-based desserts (RTE GBDs) are pre-packaged consumer baked goods such as cakes, cookies, pies, doughnuts, and pastries.
