New study explains previously mysterious characteristics of ribosomes, the protein production factories of the cell. Researchers mathematically demonstrate that ribosomes are precisely structured to build themselves as quickly as possible to support efficient cell growth.
New research in an animal model suggests a high-fat diet during pregnancy alters the development of the brain and endocrine system of offspring. The new study links an unhealthy diet during pregnancy to mental health disorders such as anxiety and depression in children.
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, as reported in the journal Angewandte Chemie.
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.
The death of a massive star in a distant galaxy 10 billion years ago created a rare superluminous supernova that astronomers say is one of the most distant ever discovered. The researchers reported their findings in a paper published on July 21 in the Monthly Notices of the Royal Astronomical Society.
A new electrochemical energy harvesting device developed at Vanderbilt University can generate electrical current from the full range of human motions and is thin enough to embed in clothing.
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.
Ion channels in the membrane vesicles that mediate intracellular protein transport play a crucial role in cell physiology. A method developed by an Ludwig-Maximilians-Universitaet (LMU) in Munich team now allows them to be studied with greater specificity than ever before.
A web that passes through infinite intergalactic spaces, a dense cosmic forest illuminated by very distant lights and a huge enigma to solve. These are the picturesque ingredients of a scientific research -- carried out by an international team composed of researchers from SISSA and the ICTP in Trieste, the Institute of Astronomy of Cambridge and the University of Washington - that adds an important element for understanding one of the fundamental components of our Universe: the dark matter.
Biochemists from the University of Freiburg have elucidated the structure of an enzyme that supplies carotenoid.
