October 14, 2013

graphene_on_glass_substrate

Researchers at the Helmholtz-Zentrum Berlin (HZB) Institute for Silicon Photovoltaics have shown that graphene retains its impressive set of properties when it is coated with a thin silicon film.

These findings may allow for entirely new possibilities to use graphene in thin-film photovoltaics.

Graphene has extreme conductivity and is completely transparent while being inexpensive and nontoxic. This would makes it a perfect candidate material… read more

Slowing down the aging process by ‘remote control’

September 10, 2014

Activating a gene called AMPK in the nervous system induces the anti-aging cellular recycling process of autophagy in both the brain and intestine. Activating AMPK in the intestine leads to increased autophagy in both the intestine and brain. Matthew Ulgherait, David Walker and UCLA colleagues showed that this 'inter-organ' communication during aging can substantially prolong the healthy lifespan of fruit flies.

UCLA biologists have identified a gene that can slow the aging process throughout the entire body when activated remotely in key organ systems.

Working with fruit flies, the life scientists activated a gene called AMPK that is a key energy sensor in cells; it gets activated when cellular energy levels are low.

Increasing the amount of AMPK in fruit flies’ intestines increased their lifespans by about 30 percent… read more

Newcastle University researchers say they have discovered how neurons age.

Experts previously identified the molecular pathway that reacts to cell damage and stems the cell’s ability to divide, known as cell senescence. However, in cells that do not have this ability to divide, such as neurons in the brain and elsewhere, little was understood of the aging process.

Now scientists at Newcastle University, led by Professorread more

European scientists from six institutes and two universities have developed an online platform where robots can learn new skills from each other worldwide — a kind of “Wikipedia for robots.”

The objective is to help develop robots better at helping elders with caring and household tasks.

“The problem right now is that robots are often developed specifically for one task”, says René van de Molengraft, TU/e researcher and… read more

Self-driving cars in 2019, report says

August 23, 2012

kpmg_self_driving_cars

Autonomous cars will be in showrooms as early as 2019, or maybe even sooner, according to a report released by KPMG and the Center for Automotive Research,

The report’s authors explain that “sensor-based technologies” and “connected-vehicle communications” need to converge. Essentially, cars need to be able to communicate with other vehicles on the road so they don’t bash into each other.

They also need the ability to sense… read more

New flexible classroom design

February 8, 2013

Classroom (credit:

Researchers at North Carolina State University have developed a classroom design that gives instructors increased flexibility in how to teach their courses and improves accessibility for students, while slashing administrative costs.

The new flexible approach acknowledges the fact that students are now bringing their own laptops to class. The classrooms also include mobile infrastructure, where whiteboards, desks and tables can be reconfigured according to the… read more

Most distant galaxy discovered: 30 billion light years away

The most distant spectroscopically confirmed galaxy ever found — one created at about 700 million years after the Big Bang — has been detected by astronomers at Texas A&M University and the University of Texas at Austin

“It’s exciting to know we’re the first people in the world to see this,” said Vithal Tilvi, a Texas A&M postdoctoral research associate and… read more

FDA clears first autonomous telemedicine robot for hospitals

Now doctors can provide patient care from anywhere in the world via a telemedicine solution. But what happens to nursing jobs, and how will patients react to a giant robotic machine?

Robot-for-hospitals

iRobot Corp., a leader in delivering robotic solutions, has announced that its RP-VITA Remote Presence Robot has received 510(k) clearance by the U.S. Food and Drug Administration (FDA) for use in hospitals. RP-VITA is the first autonomous navigation remote presence robot to receive FDA clearance.

RP-VITA is a joint effort between iRobot and InTouch Health. The robot combines the latest in autonomous navigation and mobility… read more

‘Data smashing’ could automate discovery, untouched by human hands

October 28, 2014

From recognizing speech to identifying unusual stars, new discoveries often begin with comparison of data streams to find connections and spot outliers. But simply feeding raw data into a data-analysis algorithm is unlikely to produce meaningful results, say the authors of a new Cornell study.

That’s because most data comparison algorithms today have one major weakness: somewhere, they rely on a human expert to specify what aspects of the… read more

How to connect your home appliances to the Internet of Things

Is it really smart to connect smart grids to the Internet?

sigfox

French startup SigFox thinks it can help usher in a second mobile Internet boom by connecting millions of low-power sensors worldwide to the Internet, MIT Technology Review reports.

SigFox is focused on connecting cheap sensors and “dumb” home appliances to the Internet. The goal is to make all kinds of appliances and infrastructure, from power grids to microwave ovens, smarter by letting them share data.… read more

New brain gene gives us edge over apes

November 15, 2012

human_and_ape

An international team led by the University of Edinburgh has discovered a new gene called miR-941 that helps explain how humans evolved evolved from apes by playing a crucial role in human brain development, and may shed light on how we learned to use tools and language.

The researchers say it is the first time that a new gene — carried only by humans and not by apes —… read more

Why Google’s self-driving car may save lives — if all cars are computer-driven

May 11, 2012

The technology behind Google’s self-driving car represents a potential leap forward in auto safety.

More than 30,000 people are killed each year in crashes despite huge advances in auto safety. The overwhelming majority of those crashes are caused by human-driver error.

Computer driven cars could reduce traffic deaths by a very significant degree, said David Champion, head of auto testing at Consumer Reports, but only if all cars are… read more

Defense Secretary Leon E. Panetta warned Thursday that the United States was facing the possibility of a “cyber-Pearl Harbor” and was increasingly vulnerable to foreign computer hackers who could dismantle the nation’s power grid, transportation system, financial networks and government, The New York Times reports.

He said he was reacting to increasing aggressiveness… read more

Driverless vehicles to zip at full speed through intersections

Driverless vehicles will safely wiz through intersections at the full speed limit, according to researchers from Virginia Tech Transportation Research.

Autonomous vehicles will turn themselves over to an automated intersection controller, with the controller tweaking their trajectory to prevent crashes, explained Ismail Zohdy of Cairo, Egypt, a Ph.D. student in civil engineering at Virginia Tech, and Hesham Rakha, director of the Center for Sustainableread more
