Scientists have identified the key molecular pathway leading to depression, revealing potential new targets for drug discovery, according to research led by King’s College London’s Institute of Psychiatry.

The study reveals for the first time that the “Hedgehog pathway” regulates how stress hormones, usually elevated during depression, reduce the number of brain cells.

Depression affects approximately 1 in 5 people in the UK at some point in… read more

iSpy vs. gSpy

We are all being watched, whether we like it or not.

It is a battle between you and the government — like Mad Magazine’s Spy vs. Spy comic, but it’s gSpy vs. iSpy, Andy Kessler, author of Eat People, writes in The Wall Street Journal.

There are thousands of toll booths at bridges and turnpikes across America recording your license plate. There are 4,214 red-light cameras… read more

Are you ready for computers as comedians?

January 7, 2013

As verbal interaction between humans and computers becomes more prominent in daily life — from Siri, Apple’s voice-activated assistant technology, to speech-based search engines to fully automated call centers — demand has grown for “social computers” that can communicate with humans in a natural way.

Teaching computers to grapple with humor is a key part of this equation, author Alex Stone writes in The New York Times Sunday Review.… read more

CESLexusResearch001

Toyota Motor Corporation (TMC) will reveal an advanced active safety research vehicle at the Consumer Electronics Show (CES) today (Jan. 7).

Lexus (a Toyota sales division} plans to explore the use of autonomous technologies and high-level driver assistance systems related to TMC’s  Intelligent Transport Systems (ITS) research and development, which includes vehicle-to-vehicle and vehicle-to-infrastructure communications technology.

Also highlighted at CES will be the new 2013 Lexus LS, equipped with the… read more

Billions and billions of planets

January 4, 2013

How many planets are in our galaxy?

Billions and billions of them at least. That’s the conclusion of a new study by astronomers at the California Institute of Technology, which provides yet more evidence that planetary systems are the cosmic norm.

The team made their estimate while analyzing planets orbiting a star called Kepler-32 — planets that are representative, they say, of the vast majority… read more

Promising compound restores memory loss and reverses symptoms of Alzheimer’s

New research in the FASEB Journal by NIH scientists suggests that a small molecule called TFP5 rescues plaques and tangles by blocking an overactive brain signal, thereby restoring memory in mice with Alzheimer’s — without obvious toxic side effects.

“We hope that clinical trial studies in AD patients yield an extended and a better quality of life, as observed in mice upon TFP5 treatment,” said Harish C.read more

Reducing Internet and telecom greenhouse gases

January 4, 2013

The information communications and technology (ICT) industry, which delivers Internet, video, voice and other cloud services, produces more than 830 million tons of carbon dioxide (CO2) annually — about 2 percent of global CO2 emissions — the same proportion as the aviation industry produces. This is expected to double by 2020.

Now researchers from the Centre for Energy-Efficient Telecommunications (CEET) and Bell Labs are reporting new models of emissions and… read more

NASA mulls plan to drag asteroid into moon’s orbit

January 3, 2013

asteroid

NASA is mulling over a plan to build a robotic spacecraft to grab a small asteroid and place it in high lunar orbit, according to researchers with the Keck Institute for Space Studies in California.

The mission would cost about $2.6 billion and could be completed by the 2020s, New Scientist reports.

The Obama administration has said it also wants to send astronauts to a near-Earth asteroid. One… read more

Electric stimulation of brain releases powerful, opiate-like painkiller

Researchers used electricity on certain regions in the brain of a patient with chronic, severe facial pain to release an opiate-like substance that’s considered one of the body’s most powerful painkillers.

The findings help explain what happens in the brain that decreases pain during the brief sessions of electricity, says Alexandre DaSilva, the senior researcher in the study from the University of Michigan School of… read more

Attention seniors: French scientists have developed a process that permanently dyes white hair without harmful chemicals.

Philippe Walter and colleagues soaked white hairs in a solution containing fluorescent gold nanoparticles.

The hairs turned pale yellow and then darkened to a deep brown. The color remained even after repeated washings.

Using an electron microscope, the scientists confirmed that the particles were forming inside the hairs’ central core cortex.… read more

The slower you grow, the longer you live

Fish study may also apply to humans

New research from the University of Glasgow suggests that lifespan is affected by the rate at which bodies grow early in life: manipulating growth rates in stickleback fish can extend their lifespan by nearly a third or reduce it by 15 percent.

A team from the University’s Institute of Biodiversity, Animal Health and Comparative Medicine altered the growth rate of 240 fish by exposing… read more

Why you should go paperless in 2013

Are you still printing things out? Really?

Amazingly, the average office worker still uses about 10,000 sheets of paper per year, the EPA says.

To make a new push for a really paperless office, the “Paperless Coalition,” which includes Google Drive, HelloFax, Manilla, HelloSign, Expensify, Xero and Fujitsu ScanSnap, has launched a… read more

How to watch chemo killing liver tumors in real time

Immediate feedback shows if chemotherapy worked, or if additional treatment is needed

Using two successive pairs of specialized CT scans, a team of Johns Hopkins and Dutch radiologists has produced real-time images of liver tumors dying from direct injection of anticancer drugs into the tumors and their surrounding blood vessels.

Within a minute, the images showed whether the targeted chemotherapy did or did not choke off the tumors’ blood supply and saved patients a month of worry… read more

Acrobatic space rovers to explore moons and asteroids

An autonomous system for exploring the solar system's smaller members, such as moons and asteroids, could bring us closer to a human mission to Mars
January 2, 2013

Stanford researchers in collaboration with NASA JPL and MIT have designed a robotic platform that involves a mother spacecraft deploying one or several spiked, roughly spherical rovers to the Martian moon Phobos.

Measuring about half a meter wide, each rover would hop, tumble and bound across the cratered, lopsided moon, relaying information about its origins, as well as its soil and other surface materials.

Developed by… read more
