Walking through doorways causes forgetting, new research shows

November 21, 2011

We’ve all experienced it: The frustration of entering a room and forgetting what we were going to do. Or get. Or find.

New research from University of Notre Dame Psychology Professor Gabriel Radvansky suggests that passing through doorways is the cause of these memory lapses. “Entering or exiting through a doorway serves as an ‘event boundary’ in the mind, which separates episodes of activity and… read more

Walking in nature lowers risk of depression, scientists find in MRI study

Urbanization is associated with increased levels of mental illness

rumination to sgPFC-ft

A new study has found quantifiable evidence that supports the common-sense idea that walking in nature could lower your risk of depression.

The study, published in Proceedings of the National Academy of Science, found that people who walked for 90 minutes in a natural area, as opposed to participants who walked in a high-traffic urban setting (El Camino Real in Palo Alto, California, a noisy street with three to four… read more

Walking for 40 minutes three times a week can make you smarter

August 27, 2010

Walking at one’s own pace for 40 minutes three times a week can enhance the connectivity of important brain circuits, combat declines in brain function associated with aging, and increase performance on cognitive tasks, researchers have found.

The new study used fMRI to determine whether aerobic activity increased connectivity in the default mode network (DMN), which dominates brain activity when a person is least engaged with the outside world,… read more

Walking again after spinal cord injury

June 1, 2012

Rats with spinal cord injuries and severe paralysis are now walking (and running) thanks to researchers at EPFL.

They found that a severed section of the spinal cord can make a comeback when its own innate intelligence and regenerative capacity is awakened.

The study points to a profound change in our understanding of the central nervous system. According to lead author Grégoire Courtine, it… read more

Walk like this, said the caterpillar to the robot

April 28, 2011

GoQBot

The new generation of search and rescue soft robots can wiggle their way into some tight spaces, but as for speed, not so much.

So Tufts University researchers decided to make their bots imitate caterpillars, some of which have the extraordinary ability to rapidly curl themselves into a wheel and propel themselves away from predators — really fast.

It’s called “ballistic rolling— one of the fastest wheeling… read more

Walgreen To Sell Pathway Genomics Genetic Test Kits Mid-May

May 12, 2010

Walgreen Co. will sell genetic tests in about 6,000 of its stores starting in mid-May to help evaluate a person’s relative risk of developing certain diseases.

Walgreen plans to offer Pathway’s Insight Saliva Collection Kit at retail from $20 to $30. The saliva test, which will be done at Pathway’s labs, will cost between $79 and $249. Genetic tests typically cost about $300.

Wake-up call to genes may lead to cure for baldness

May 20, 2007

Scientists have found a way to regenerate hair follicles that may lead to a cure for baldness, by reawakening genes once active only in developing embryos.

Waiting for the lights to go out

October 19, 2005

“The greatest getting-and-spending spree in the history of the world is about to end,” says Matthew Stein in his book, When Technology Fails: A Manual for Self-Reliance and Planetary Survival.

“The 200-year boom that gave citizens of the industrial world levels of wealth, health and longevity beyond anything previously known to humanity is threatened on every side. Oil is running out; the climate is changing at a potentially catastrophic… read more

Waiting for Flexible Displays and Flexible Devices

January 18, 2010

We could expect to see flexible displays in the marketplace in the next three to five years, but the other components are a little further out, says Nicholas Colaneri, director of the Flexible Display Center at Arizona State University.

Waiter, There’s a Drug in My Rice

March 31, 2004

The California Rice Commission on Monday approved Ventria Bioscience’s request to grow the state’s first crop genetically modified to contain a drug.

The rice is genetically modified to produce two human proteins that fight infection: lactoferrin and lysozyme, both naturally present in breast milk.

Opponents say growing the crops in open fields endangers organic and conventional crops, as well as human health.

Wait, some stem cells use nanotubes to communicate with other cells? Seriously?

Certain types of stem cells use microscopic, threadlike nanotubes to communicate with neighboring cells, rather than sending a broadcast signal, researchers at University of Michigan Life Sciences Institute and University of Texas Southwestern Medical Center have discovered.

The fruit-fly research findings, published today (July 1) in Nature, suggest that short-range, cell-to-cell communication may rely on this type of direct connection more than was previously understood, said… read more

Mark Wahlberg and Liam Neeson are mulling over offers to headline director Vicenzo Natali’s long-gestating adaptation of William Gibson‘s Neuromancer, Moviehole reports.

Wahlberg would play the anti-hero Case and Neeson would play Armitage.

 

Waging war by remote control

October 18, 2001

The United States is for the first time flying armed, unmanned aircraft into combat and controlling them with operators in the United States via satellite.The use of the armed RQ-1 Predator drone planes is a revolutionary step in the conduct of warfare because they signal that the Air Force is now able to survey and then shoot at ground positions from lower altitudes without putting pilots at risk.

Wafer-scale, flexible thin-film electronics

Can even wrap around a human hair
January 14, 2014

ultrathin_electronic_membrane

Researchers at ETH Zurich are developing thin-film transistors, sensors, and other electronic components that are thin and flexible enough to be wrapped around a wide range of surfaces without damaging the electronics.

The aim is to weave these types of components into textiles or apply them to the skin to make “smart,” unobtrusive, comfortable sensors  that can monitor various functions of the body, aka “temporary tattoo” biosensors.… read more

Vulcan project aims to build ‘Digital Aristotle’

February 13, 2004

Can a computer be loaded with the world’s textbook-science knowledge, reason through it and then answer questions in plain English like a phenomenal teacher, a “Digital Aristotle”?

Paul Allen’s private investment company, Vulcan, has announced it is willing to bankroll three competing research teams from around the world to answer this question, in what it calls “Project Halo,” a quest over the next 30 months to create a computerized… read more
