Researchers have pieced together a set of puzzling fossils from a stocky dinosaur discovered in Romania. The newly described predator helps to flesh out the spotty fossil record of carnivorous animals from Europe's Cretaceous...
An apple a day keeps the doctor away, but can knowing its genetic secrets help feed the nine billion people expected on this planet by 2050? Scientists hope so, especially considering they have added wheat this week to the list of crops that have had their genetic instruction set read...
It looks like a solar-powered treadmill, but researchers at the Massachusetts Institute of Technology (M.I.T.) say they have created a flat, conveyor belt–like device that could clean up oil slicks far more efficiently than anything used at the Deepwater Horizon site...
The benefits of breast-feeding for babies have proved to be myriad, and an increasing number of studies are finding long-term health benefits for mothers, too, including reduced risk of cardiovascular disease and lower odds of some cancers...

Inside cells, some DNA is wound into tight packets, known as nucleosomes. Special enzymes bind to these compact packages of genetic material, helping to activate genes.
Electromagnetic pulses from far-flung celestial objects can provide a sort of scale with which to gauge the mass of the planets, according to a new study.
A new analysis of a meteorite shows that an inclusion within the carbonaceous stone is older than any known material in the solar system. The finding pushes back the estimated age of the solar system to 4.568 billion years, older than previous estimates by up to 1.9 million years...
