LCD projector used to control brain, muscles of tiny organisms such as worms

Researchers are using inexpensive components from ordinary liquid crystal display (LCD) projectors to control the brain and muscles of tiny organisms, including freely moving worms. Red, green and blue lights from a projector activate light-sensitive microbial proteins that are genetically engineered into the worms, allowing the researchers to switch neurons on and off like light bulbs and turn...

'Electron vortices' have the potential to increase conventional microscopes' capabilities

(PhysOrg.com) -- Electron microscopes are among the most widely used scientific and medical tools for studying and understanding a wide range of materials, from biological tissue to miniature magnetic devices, at tiny levels of detail. Now, researchers at the National Institute of Standards and Technology have found a novel and potentially widely applicable method to expand the capabilities of...

In scientific first, researchers visualize naturally occurring mRNA

In a technique that could eventually shed light on how gene expression influences human disease, scientists at Albert Einstein College of Medicine of Yeshiva University have for the first time ever successfully visualized single molecules of naturally-occurring messenger RNA (mRNA) transcribed in living mammalian cells. The scientific achievement is detailed in the January 16 online edition of...

MicroRNA suppresses prostate cancer stem cells and metastasis

A small slice of RNA inhibits prostate cancer metastasis by suppressing a surface protein commonly found on prostate cancer stem cells. A research team led by scientists at The University of Texas MD Anderson Cancer Center reported today in an advance online publication at Nature Medicine.

CU researchers use technological innovation to study bone structure

A team of researchers at Columbia Engineering and Columbia University Medical Center announced today the results of the first study comparing bone structure in Chinese-American women to Caucasian women. The report, just presented at the Orthopaedic Research Society's annual meeting at Long Beach, CA, found that pre-menopausal Chinese-American women have far greater bone strength than their...

(AP) -- In a cautionary tale for users of social-networking sites, a California man has admitted using personal information he gleaned from Facebook to hack into women's e-mail accounts, then send nude pictures of them to everyone in their address book.

Green super rice is coming

Rice bred to perform well in the toughest conditions where the poorest farmers grow rice is a step away from reaching farmers thanks to a major project led by the Chinese Academy of Agricultural Sciences and the International Rice Research Institute (IRRI).
