Astronomy & Space news

Cassini caught in Hyperion's particle beam

Static electricity is known to play an important role on Earth's airless, dusty moon, but evidence of static charge building up on other objects in the solar system has been elusive until now. A new analysis of data from NASA's Cassini mission has revealed that, during a 2005 flyby of Saturn's moon Hyperion, the spacecraft was briefly bathed in a beam of electrons coming from the moon's electrostatically charged surface.

NASA's Hubble telescope finds potential Kuiper belt targets for New Horizons Pluto mission

Peering out to the dim, outer reaches of our solar system, NASA's Hubble Space Telescope has uncovered three Kuiper Belt objects (KBOs) the agency's New Horizons spacecraft could potentially visit after it flies by Pluto in July 2015.

Who owns the moon?

Whether you're into mining, energy or tourism, there are lots of reasons to explore space. Some "pioneers" even believe humanity's survival depends on colonising celestial bodies such as the moon and Mars, both becoming central hubs for our further journey into the cosmos. Lunar land peddlers have started doing deals already – a one-acre plot can be yours for just £16.75.

A newborn supernova every night

Thanks to a $9 million grant from the National Science Foundation and matching funds from the Zwicky Transient Facility (ZTF) collaboration, a new camera is being built at Caltech's Palomar Observatory that will be able to survey the entire Northern Hemisphere sky in a single night, searching for supernovas, black holes, near-Earth asteroids, and other objects. The digital camera will be mounted on the Samuel Oschin Telescope, a wide-field Schmidt telescope that began its first all-sky survey in 1949. That survey, done on glass plates, took nearly a decade to complete.

Top-secret space plane lands on California coast

(AP)—A top-secret space plane landed Friday at an Air Force base on the Southern California coast.

Argentina launches its first home-built satellite

(AP)—Argentina launched its first domestically built communications satellite Thursday.

Opportunity rover gets panorama image at 'Wdowiak Ridge'

The latest fieldwork site for NASA's Mars Exploration Rover Opportunity, which has been examining a series of Martian craters since 2004, is on the slope of a prominent hill jutting out of the rim of a large crater and bearing its own much smaller crater. It's called "Wdowiak Ridge."

Fifth launch for Ariane 5 this year (w/ Video)

An Ariane 5 has lifted off from Europe's Spaceport in Kourou, French Guiana and delivered two telecom satellites, Intelsat-30/DLA-1 and Arsat-1, into their planned orbits.

See one of the year's best meteor showers, thanks to Halley's comet

As Earth orbits the sun, it continually ploughs through dust and debris left behind by passing comets and asteroids. On any night of the year, a keen-eyed observer might see five, or even ten, meteors (shooting stars) per hour.

NASA investigating deep-space hibernation technology

Manned missions to deep space present numerous challenges. In addition to the sheer amount of food, water and air necessary to keep a crew alive for months (or years) at a time, there's also the question of keeping them busy for the entirety of a long-duration flight. Exercise is certainly an option, but the necessary equipment will take up space and be a drain on power.

Medicine & Health news

Young adults found displaying symptoms of net addiction

In 2012, Allen Frances, MD, professor emeritus and former chair of the department of psychiatry at Duke University, cautioned that "Internet Addiction" could be the next new fad diagnosis, complete with "an exuberant trumpeting by newly minted 'thought leading' researchers and clinicians." So far, he said, the research on Internet "addiction" is "remarkably thin and not very informative." He cautioned that pictures showing the same parts of the brain lighting up during Internet use and drug use should not get viewers too excited, as they "light up non-specifically for any highly valued activity and are not indicative of pathology."

How pairs of proteins collaborate to splice RNAs into cell-specific products

A team of scientists led by RIKEN researcher Yutaka Muto, in collaboration with Hidehito Kuroyanagi of Tokyo Medical and Dental University and Masatoshi Hagiwara of Kyoto University, has revealed some of the mechanisms that regulate the mysterious RNA splicing process that produces specific protein variants.

How the brain leads us to believe we have sharp vision

Its central finding is that our nervous system uses past visual experiences to predict how blurred objects would look in sharp detail.

Study finds that action video games bolster sensorimotor skills

A study led by University of Toronto psychology researchers has found that people who play action video games such as Call of Duty or Assassin's Creed seem to learn a new sensorimotor skill more quickly than non-gamers do.

School and job failure may increase drug users' risks of suffering a fatal overdose

For the first time, researchers have found that problem drug users with less successful educational and employment careers are more likely to die of an overdose. Moreover, there is no link between parents' professional status and the likelihood that their problem drug-using child will die from an overdose.

Presence of enzyme may worsen effects of spinal cord injury and impair long-term recovery

Traumatic spinal cord injury (SCI) is a devastating condition with few treatment options. Studies show that damage to the barrier separating blood from the spinal cord can contribute to the neurologic deficits that arise secondary to the initial trauma. Through a series of sophisticated experiments, researchers reporting in The American Journal of Pathology suggest that matrix metalloproteinase-3 (MMP-3) plays a pivotal role in disruption of the brain/spinal cord barrier (BSCB), cell death, and functional deficits after SCI. This link also presents new therapeutic possibilities.

Improving the view through tissues and organs

This summer, several undergraduate students at Caltech had the opportunity to help optimize a promising technique that can make tissues and organs—even entire organisms—transparent for study. As part of the Summer Undergraduate Research Fellowship (SURF) program, these students worked in the lab of Assistant Professor of Biology Viviana Gradinaru, where researchers are developing such so-called clearing techniques that make it possible to peer straight through normally opaque tissues rather than seeing them only as thinly sectioned slices that have been pieced back together.

Study finds inconsistent achievement of guidelines for acute asthma care in hospital EDs

A study comparing the care delivered to patients coming to hospital emergency departments (EDs) for acute asthma attacks in recent years with data gathered more than 15 years earlier finds inconsistencies in how well hospitals are meeting nationally established treatment guidelines. A team led by Massachusetts General Hospital (MGH) investigators found that, while the achievement of most guidelines defining appropriate pharmacologic treatments for particular patients improved over the study period, hospitals did less well in meeting several other guidelines. The study that will appear in the Journal of Allergy and Clinical Immunology has been published online.

Image guided radiation therapy is commonly used to ensure accuracy in treating pediatric tumors
