Applying a gentle electric current to the brain during sleep can significantly boost memory, University of Luebeck researchers report.
They believe this is due to the pattern of the applied current mimicking that seen in naturally occurring deep sleep, where memory consolidation is thought to take place.

Engineers at the University of Texas at Austin have patented a laser microscalpel that allows a surgeon to operate on tissue one cell at a time, precisely targeting disease while leaving healthy surrounding cells alive.
The device combines two technologies–a femtosecond laser and two-photon fluorescence microscopy–into a single miniaturized, flexible probe. The probe can target single cells in three-dimensional space, penetrating up to 250 micrometers into tissue.

Magnetic nanoparticles can be used to kill cancer cells by controlling cell signaling pathways, researchers from Yonsei University in South Korea have demonstrated.
They developed magnetic nanoparticles that turn on apoptosis cell signaling (commands to kill cells) in cancer cells by using a remote, non-invasive magnetic field.
The magnetic switch uses zinc-doped iron oxide magnetic nanoparticles (Zn0.4Fe2.6O4), combined with a targeting antibody for death receptor 4 (DR4, a… read more
No, it’s not a new version of the classic Asteroids video game. Engineers at the University of Strathclyde in Glasgow have envisioned a swarm of small agile satellites flying in formation, firing solar-powered lasers at an asteroid.
According to Dr. Massimiliano Vasile, of Strathclyde’s Department of Mechanical and Aerospace Engineering, the concept is more feasible than a single large spacecraft carrying a multi-mega watt laser.
“Our system is… read more

A new project by Coriell Institute for Medical Research aims to incorporate the results of genetic screening into medicine.
The researchers will evaluate the relevance of specific genes in terms of their disease risk and clinical utility, and make a direct effort to involve medical professionals.
Unlike some private services, the Coriell project will give participants only that genetic information deemed by an advisory board to be medically… read more

YouTube will provide an option for full HD 1080p resolution and a new full-screen player within days.
July 12, 2010
YouTube has announced that its player now supports 4k, a standard resolution for films that measures 4096×3072 pixels (requiring special equipment to view).
As YouTube Engineer Ramesh Sarukkai explained in the announcement on YouTube’s official blog, “4K is nearly four times the size of 1080p,” and it dwarfs even Imax, which projects films in the slightly smaller 2k format, with its 2048?1080-pixel resolution.
