Study shows how DNA finds its match
It's been more than 50 years since James Watson and Francis Crick showed that DNA is a double helix of two strands that complement each other. But how does a short piece of DNA find its match, out of the millions ...
A spider web's strength lies in more than its silk
While researchers have long known of the incredible strength of spider silk, the robust nature of the tiny filaments cannot alone explain how webs survive multiple tears and winds that exceed hurricane strength.
Astronomers probe 'sandbar' between islands of galaxies
(PhysOrg.com) -- Astronomers have caught sight of an unusual galaxy that has illuminated new details about a celestial "sandbar" connecting two massive islands of galaxies. The research was conducted in part ...
Mining bacterial genomes reveals valuable 'hidden' drugs
A new tool to excavate bacterial genomes that potentially hide a rich array of pharmaceutical treasures has led to the discovery of a novel antibiotic. The study, reported in the August issue of Microbiology, could ...
Fibers that can hear and sing
For centuries, "man-made fibers" meant the raw stuff of clothes and ropes; in the information age, it's come to mean the filaments of glass that carry data in communications networks. But to Yoel Fink, an ...
Hydrogen still in the eco-car race
(AP) -- Hydrogen, one of Earth's most abundant elements, once was seen as green energy's answer to the petroleum-driven car: easy to produce, available everywhere and nonpolluting when burned.
