UCLA group discovers humongous prime number
(AP) -- Mathematicians at UCLA have discovered a 13 million-digit prime number, a long-sought milestone that makes them eligible for a $100,000 prize.
Near Infrared Nanoparticles Shine A Bright Light On Cancer
A new imaging method for breast cancer has been developed. More effective early detection of diseases is one of the promises of nanotechnology. Current imaging methods, such as x-rays and...
Tsunami Invisibility Cloak
Rather than building stronger ocean-based structures to withstand tsunamis, it might be easier to simply make the structures disappear.
Tweezers Trap Nanotubes By Color
Singled-walled carbon nanotubes are graphene sheets wrapped into tubes, and are typically made up of various sizes and with different amounts of twist (also known as chiralities). Each type of...
Bacteria ready to make plastic from sugar
Claims of biology-based oil and plastic usually bear the caveat "in five years." But a San Diego-based company claims they will have a pilot plant for production of E. coli-based...
New More Efficient Ways To Use Biomass
Researchers have developed a new catalyst that directly converts cellulose, the most common form of biomass, into ethylene glycol, an important intermediate product for chemical industry.
VIDEO: Needle-Free Injection Invented
Needle-free syringes use air pressure or gases to deliver drugs, and a Japanese inventor says he's gone even further to cut costs and improve efficiency.
Cracking charge density
UK scientists answer the all important question: how many electrons are there on each atom in a molecule?
Engineer: Head-first slide is quicker
Base running and base stealing would seem to be arts driven solely by a runner's speed, but there's more than mere gristle, bone and lung power to this facet of...
CERN sticks to opening gala despite atom-smasher troubles
Europe's leading physicists will swap their lab coats for their best suits next month for the official inauguration of a multi-billion dollar machine designed to shed light on the "Big...
