Optimization for self-production may explain mysterious features of the ribosome

A new study explains the previously mysterious characteristics of ribosomes, the protein production factories of the cell. Researchers mathematically demonstrated that ribosomes are precisely structured to build themselves as quickly as possible to support efficient cell growth.

Cecil the lion's son killed in trophy hunt

Xanda, a 6-year-old lion that was the son of Cecil, was shot dead during a legal hunting safari in Zimbabwe.

Name that scotch: Colorimetric recognition of aldehydes and ketones

Vodka tastes different from brandy, and connoisseurs can distinguish among different brands of whiskeys. The flavors of spirits result from a complex bouquet of volatile compounds. New colorimetric sensor arrays on disposable test-strips read by hand-held devices allow for their rapid, inexpensive, and sensitive identification by their chemical 'fingerprints'. They are based on novel sensor arrays that detect and differentiate among a diverse range of aldehydes and ketones.

Rush hour pollution may be more dangerous than you think

Everyone knows that exposure to pollution during rush hour traffic can be hazardous to your health, but it's even worse than previously thought. In-car measurements of pollutants that cause oxidative stress found exposure levels for drivers to be twice as high as previously believed.

Good fighters are bad runners

For mice and men, a strength in one area of Darwinian fitness may mean a deficiency in another. A look at Olympic athletes shows that a wrestler is built much differently than a marathoner. It's long been supposed that strength in fighting, or protecting territory and resources, comes at the expense of running, or spatial mobility. Now an experiment with house mice provides evidence for this theory.

3-D scanning with water

An innovative technique has been developed that more completely reconstructs challenging 3-D objects. This new approach to 3-D shape acquisition is based on the well-known fluid displacement discovery by Archimedes and turns modeling surface reconstruction into a volumetric problem. Their method accurately reconstructs even hidden parts of an object that typical 3-D laser scanners are not able to capture.

Ultrathin device harvests electricity from human motion

A new electrochemical energy harvesting device can generate electrical current from the full range of human motions and is thin enough to embed in clothing.

Your stinky feet can reveal who you’re living with

Couple in bed

Sharing a life means sharing your microbes.

The story of love is also the story of slowing sharing more and more of your microbiome with another human being. This is truly the stuff of romance novels.

Superluminous supernova marks the death of a star at cosmic high noon

The death of a massive star in a distant galaxy 10 billion years ago created a rare superluminous supernova, one of the most distant ever discovered. The brilliant explosion, more than three times as bright as the 100 billion stars of our Milky Way galaxy combined, occurred about 3.5 billion years after the big bang at a period known as 'cosmic high noon,' when the rate of star formation in the universe reached its peak.
