Several proteins are now known to influence longevity, energy use and the response to caloric restriction, including sirtuins (thought to help the body ride out famines), receptors for insulin, IGF-1, and TOR ("target of rapamycin") -- an antimicrobial that was recently found to extend lifespan significantly, even when given to mice at an advanced age).Four active clinical trials of sirtuin activators (drugs that mimic resveratrol) are under way b...

(US Pharmacopeia) Counterfeit and adulterated food and drugs and advances in measurement science used to detect them emerged as key themes of the Annual Scientific Meeting hosted by the US Pharmacopeial Convention. Held in Toronto, Canada, more than 300 people from 26 countries attended, making this a truly multinational event. Experts from all countries need to grapple with the worldwide proliferation of fakes -- notably manifest in drugs sold ov... More

We will be able to upload the human brain to a computer, capturing "a person's entire personality, memory, skills and history," by the end of the 2030s; humans and non-biological machines will then merge so effectively that the differences between them will no longer matter; and, after that, human intelligence, transformed for the better, will start to expand outward into the universe, about 2045, says Ray Kurzweil.

A new mathematical model developed by Rockefeller University scientists describes how the trillions of interconnections among neurons could maintain a stable but dynamic relationship that leaves the brain sensitive enough to respond to stimulation without veering into a blind seizure: neurons function together in localized groups to preserve stability.The new model differs from the traditional Hebbian model of neural networks, which assume that ea...

UC San Diego physicists have created integrated circuits with particles called "excitons" at 125 degrees Kelvin (can be easily attained commercially with liquid nitrogen), bringing the possibility of a new type of extremely fast computer based on excitons closer to reality.Excitons are pairs of negatively charged electrons and positively charged holes that can be created by light in a semiconductor such as gallium arsenide. When the electron and ... More

Researchers at Cornell University have developed a simple device that could be used to move vast quantities of data at fast speeds over the Internet or on optical chips inside computers, using a silicon chip called a "time lens," lengths of optical fiber, and a laser.It splits up a data stream encoded at 10 gigabits per second, puts it back together, and outputs the same data at 270 gigabits per second. It could also be a critical step in the deve... More

Technion-Israel Institute of Technology researchers have designed a blueprint for a "photonic machine gun" that could fire out 12 qubits on demand. It uses a quantum dot (nanoscale crystal within a semiconducting device) chilled to a low temperature. When a short, strong pulse of light hits the dot, one of the electrons inside is raised to an excited state. As it "relaxes" back to its resting energy state it throws out a photon.

(American Physical Society) Working toward ever lower temperatures is only part of the battle for physicists studying ultra-cold systems of atoms. A group of researchers has now found a way to deal with disorder as well, as they pump entropy away from an atomic gas.

(Durham University) Decision-making on science - especially emerging technologies such as nanotechnology -- must become more democratic, a new report on science policy released today argues. The group of leading European academics behind the "Reconfiguring Responsibility" report argue forcefully that current governance activities are limiting public debate and may repeat mistakes made in managing GM.
