Along with its main mission of scientific research, NASA's Cassini orbiter is one heck of a photographer.
NASA just released the striking image above, which shows the upper layers of Saturn's atmosphere illuminated by the eclipsed Sun. And that's far from the the only modernist photo Cassini has snapped over the years.
Autistic children have distinctive chemicals in their urine, according to a study by British researchers who say the results could pave the way for an diagnostic test for the disorder.
The finding also lends more weight to theories that substances related to gut bacteria may contribute to autism, New Scientist reports.
Researchers have found a novel method for stopping the spread of influenza viruses, a finding that could lead to a universal treatment for flu. The method involves stopping the genetic process by which the virus replicates itself. Researchers can essentially flip a switch that stops RNA in its tracks.
Sensors built into cellphones could detect hazardous chemicals and spread the word to people nearby

Your smartphone can post Twitter updates and find late-night pizza. But warn you of a hazardous chemical spill? Soon there will be an app for that too. The Department of Homeland Security is working on technology that allows cellphones to double as chemical detectors.
Nanowires inside a rat can convert the power of breathing and heartbeats into electricity, according to researchers at the Georgia Institute of Technology. The nano-generator could conceivably lead to nano-scale medical implants and sensors powered by the body, Technology Review reports.
Something is consuming hydrogen and organic molecules on Saturn's moon Titan, and the recipe matches astrobiologists' theories about possible methane-based life. Granted, there may be other chemical explanations -- it's just that no one knows what they are yet.
New data from the Cassini spacecraft show hydrogen is disappearing near Titan's surface. What's more, scientists have not been able to find acetylene, an organic molecule that should be pretty abundant in the moon's thick atmosphere.
All this fits very nicely with a theory from NASA astrobiologist Chris McKay, who proposed five years ago that microbial life on Titan could breathe hydrogen and eat acetylene, producing methane as a result.
In a breakthrough that could shake up the way researchers think about cancer vaccines, researchers at the Cleveland Clinic have found a protein that appears to prepare the immune system to prevent cancer.
Just about everyone can think of some memory he or she would rather forget. For some, it's something like a relationship gone wrong, or high school. For others -- like soldiers returning from war zones -- those bad memories can be highly disruptive, impeding the ability to live a normal life. But Puerto Rican researchers may have found a way to reduce the fear associated with our memories by injecting a naturally occurring chemical directly into the brain, replacing anxiety with feelings of security.
Cycling helmets serve but one singular purpose: protecting your cranium when speed and gravity conspire against your cycling prowess. But a helmet that's damaged -- even slightly damaged -- can fail when you need it the most. Compounding the problem is the fact that it's very hard to detect hairline cracks or other flaws in a cycling helmet that result from routine wear and tear. That's why researchers at Germany's Fraunhofer Institute have engineered the first bicycle helmet that literally makes a stink when it becomes damaged.
