Brain-boosting technique might help some functions while hurting others

March 6, 2013

transcranial_stimulation

Electrically stimulating the brain may enhance memory, but impede a person’s ability to react without thinking, MIT Technology Review reports.

Using a noninvasive technique called transcranial electrical stimulation (TES) to stimulate the brain, researchers found they could enhance learning when they targeted a certain spot.

But that also made people worse at automaticity, or the ability to perform a task without really thinking about it. Stimulating another… read more

New results indicate that new particle is a Higgs boson

March 14, 2013

An example of simulated data modelled for the CMS particle detector on the Large Hadron Collider (LHC) at CERN. Here, following a collision of two protons, a Higgs boson is produced which decays into two jets of hadrons and two electrons. The lines represent the possible paths of particles produced by the proton-proton collision in the detector while the energy these particles deposit is shown in blue. (Image credit: CERN)

At the recent Moriond Conference, the ATLAS and CMS collaborations at the Large Hadron Collider (LHC) presented preliminary new results, finding that the new particle is looking more and more like a Higgs boson, the particle linked to the mechanism that gives mass to elementary particles.

It remains an open question, however, whether this is the Higgs… read more

World’s first green piglets born in China, sheep next

In Guangdong Province in Southern China, ten transgenic piglets have been born this year, in  and under a black light, they glow a greenish tint.

A technique developed by reproductive scientists from the University of Hawai`i at Mānoa’s John A. Burns School of Medicine was used to quadruple the success rate at which plasmids carrying a fluorescent protein from jellyfish DNA were transferred into the… read more

Chronic stroke patients safely recover after injection of human stem cells

Stanford researchers now actively recruiting 156 patients for new trial
June 3, 2016

Sonia Olea Coontz had a stroke in 2011 that affected the movement of her right arm and leg. After modified stem cells were injected into her brain as part of a clinical trial, she says her limbs "woke up." (credit: Mark Rightmire/Stanford University School of Medicine)

Injecting specially prepared human adult stem cells directly into the brains of chronic stroke patients proved safe and effective in restoring motor (muscle) function in a small clinical trial led by Stanford University School of Medicine investigators.

The 18 patients had suffered their first and only stroke between six months and three years before receiving the injections, which involved drilling a small hole through their skulls.

Flexible sensors turn skin into a touch-sensitive interface for mobile devices

March 4, 2015

iSkin2

Computer scientists at Saarland University and Carnegie Mellon University are studying the potential use of the human body as a touch sensitive surface for controlling mobile devices. They have developed flexible silicone rubber stickers with pressure-sensitive sensors that fit snugly to the skin.

By operating these touch input stickers, users can use their own body to control mobile devices. Because of the flexible material used, the sensors can be… read more

New solar structure cools buildings in full sunlight, replacing air conditioners

Homes and buildings chilled without air conditioners? Car interiors that don't heat up in the summer sun? Tapping the frigid expanses of outer space to cool the planet? Yes.

sunlight_building

Stanford University researchers have designed an entirely new form of cooling structure that cools even when the sun is shining, eliminating the need for air conditioning.

Such a structure could vastly improve the daylight cooling of buildings, cars, and other structures by reflecting sunlight back into space.

“We’ve developed a new type of structure that reflects the vast majority of sunlight, while at the same… read more

Thiel tells Schmidt: ‘Google is out of ideas’

July 18, 2012

Google Chairman Eric Schmidt and investor Peter Thiel took aim at each other in a recent debate, CNET reports.

Schmidt said technology and access to information has increased productivity and quality of life worldwide. Thiel thanked Schmidt for “doing a fantastic job” as “minister of propaganda” for Google. The tech sector has made remarkable strides in the areas of computers and software, he said, but has seen a “catastrophic” failure in other… read more

Immortal worms defy aging

February 29, 2012

Planarian flatworm

Researchers from The University of Nottingham have discovered how planarian flatworms overcome the aging process to be potentially immortal: they can rejuvenate their telomeres.

The discovery, funded by the Biotechnology and Biological Sciences Research Council (BBSRC) and Medical Research Council (MRC), may eventually lead to alleviating aging and age-related characteristics in human cells.

Planarian worms have amazed scientists with their apparently limitless ability to regenerate. Researchers have… read more

Researchers at BGI (formerly the Beijing Genomics Institute) in Shenzhen, China, the largest gene-sequencing facility in the world, are searching for the quirks of DNA that may contribute to genius in an ethically controversial study.

They are scouring the genomes of 1,600 U.S. adolescents who signed up for the Study of Mathematically Precocious Youth (SMPY) in the 1970s, Nature News reports.

Some geneticists say that the… read more

How terahertz laser scanners will spy on you in airports

Genia

Genia Photonics has developed a programmable picosecond laser that is capable of spotting trace amounts of a variety of substances, including explosives, chemical agents, and hazardous biological substances at up to 50 meters.

It’s basically a spectrometer for radiation in the terahertz band. The beam used by Genia’s spectrometer is capable of penetrating most materials including wood, leather, cloth, ceramics, plastic, and paper, and can essentially… read more

A radical new holistic view of health based on cooperation and disease based on competition

Researchers at The Mount Sinai Medical Center have developed a radical holistic view of health — seeing it as a cooperative state among cells, while they see disease as result of cells at war that fight with each other for domination.

Their unique approach is backed by experimental evidence. The researchers show a network of genes in cells, which includes the powerful tumor suppressor p53,… read more

Wind could meet many times the world’s total power demand by 2030, Stanford researchers say

September 11, 2012

wind farms

Researchers at Stanford University’s School of Engineering and the University of Delaware have used what they call the “most sophisticated weather model available” to  meet many times the world’s total power demand by 2030 — in fact, enough to exceed the total demand by several times, even after accounting for reductions in wind speed caused by turbines.

In related news today, Lawrence Livermore and Carnegie Institute researchers have found… read more

This app lets autonomous video drones with facial recognition target persons

One small step for selfies, one giant leap for cheap deep-learning autonomous video-surveillance drones

Robotics company Neurala has combined facial-recognition and drone-control mobile software in an iOS/Android app called “Selfie Dronie” that enables low-cost Parrot Bebop and Bebop 2 drones to take hands-free videos and follow a subject autonomously.

To create a video, you simply select the person or object and you’re done. The drone then flies an arc around the subject to take a video selfie (it moves with the… read more
