Helmet with ultrasound sensors could help firefighters detect objects in the dark

April 3, 2013

helmet

A “tactile helmet” with ultrasound sensors has been developed by researchers at the University of Sheffield Center for Robotics. It could provide fire-fighters operating in the dark or other challenging conditions with vital clues about their surroundings.

The helmet has a number of ultrasound sensors that are used to detect the distances between the helmet and nearby walls or other obstacles. These signals are transmitted to… read more

Among a significant percentage of patients, the risk of metastasis of cancer is particularly expressed by the presence of an abnormal amount of protein HER2 on the surface of cancer cells.

A new in vitro system for identification of these proteins in diseased tissues. has been developed by EPFL and Institute of Pathology at the Lausanne University Hospital (CHUV) scientists. It is extremely fast, precise, inexpensive, and… read more

Scientists have replicated the behavior of a colony of ants on the move with the use of miniature robots, as reported in the open access journal PLOS Computational Biology.

The researchers, based at the New Jersey Institute of Technology (Newark, USA) and at the Research Centre on Animal Cognition (Toulouse, France), aimed to discover how individual ants, when part of a moving colony, orient themselves in the… read more

Head-on collisions between DNA-code reading machineries accelerate gene evolution

April 2, 2013

dnasplit

Bacteria appear to speed up their evolution by positioning specific genes along the route of expected traffic jams in DNA encoding. Certain genes are in prime collision paths for the moving molecular machineries that read the DNA code, as University of Washington scientists explain in this week’s edition of Nature.

The spatial-organization tactics that the researchers’ model organism, Bacillus subtilis, takes to evolve and adapt might be… read more

President Obama on Tuesday will announce specifics on the Brain Activity Map project Tuesday, The New York Times reports. The initiative, which will officially be known as Brain Research Through Advancing Innovative Neurotechnologies, or Brain for short, has been designated a grand challenge of the 21st century by the Obama administration.

The broad new research initiative, starting with $100 million in 2014, is intended to invent and… read more

Designer carbon provides longer battery life

Energ2’s nanostructured carbon anodes can boost lithium-ion battery capacity by 30 percent
April 2, 2013

HybridBatteryEnerg2

EnerG2 has developed a carbon anode that improves the storage capacity of lithium-ion batteries by up to 30 percent without requiring a new battery design or a different manufacturing process, MIT Technology Review reports.

EnerG2’s new lithium-ion battery anode is made of a form of carbon in which the atoms have a disorganized, amorphous structure, compared to the crystalline structure of graphite, the material normally… read more

Using a Kinect depth camera and some ingenious computer vision algorithms, SimSensei can diagnose whether you’re depressed or not with 90% accuracy, MIT Technology Review reports.

The system uses an interactive digital avatar to conduct a verbal interview with the person being screened for depression.Skeletal polygonal overlays map the depressed human’s posture, gaze direction, and even “smile level.”

Blue Waters, one of the world’s most powerful computers, opens for research

April 2, 2013

Blue Waters has been configured to solve the most challenging compute-, memory- and data-intensive problems in science and engineering. It has tens of thousands of chips (CPUs & GPUs), more than a petabyte of memory, tens of petabytes of disk storage, and hundreds of petabytes of archival storage. (Credit: NCSA/University of Illinois)

Blue Waters, one of the most powerful supercomputers in the world, was formally declared available for use today at the National Center for Supercomputing Applications at the University of Illinois at Urbana-Champaign (UIUC).

Blue Waters, a partnership among NSF, the State of Illinois, the University of Illinois and the Great Lakes Consortium for Petascale Computation, is capable at peak performance of nearly  12 petaFLOPS (12… read more

Virginia Tech College of Engineering researchers are working on a multi-university, nationwide project for the U.S. Navy that one day will put life-like autonomous robot jellyfish in waters around the world.

Uses of the robot jellyfish could include conducting military surveillance, cleaning oil spills, and monitoring the environment.

The main focus of the program is to understand the fundamentals of… read more

University of Copenhagen researchers and an international team have for the first time mapped telomerase, an enzyme with a rejuvenating effect on cell aging.

This is one of the results of a major research project involving more than 1,000 researchers worldwide, four years of hard work, DKK 55 million from the EU, and blood samples from more than 200,000 people.

It is the largest collaboration project… read more

Smell-o-Vision is finally here

April 1, 2013

smelling_screen

Smell-O-Vision was a system that released odors during the projection of a film so that the viewer could “smell” what was happening in the movie.

Now the “smelling screen,” invented by Haruka Matsukura at Tokyo University of Agriculture and Technology in Japan and colleagues, makes smells appear to come from the exact spot on any LCD screen that is displaying the image of a cup of coffee,… read more

It was the largest online attack ever reported. Over the course of the past week, servers belonging to an international non-profit company called The Spamhaus Project, which fights email spammers, were inundated with up to 38 gigabytes of traffic each second, New Scientist reports.

The attackers exploited open domain name server (DNS) resolvers, faking their own IP addresses, replacing them with the address of the target. This… read more

TED removes TEDxWestHollywood license: ideas that have ‘failed to gain scientific acceptance’

April 1, 2013

Ex-TED

TED has removed the license of TEDxWestHollywood for their planned “Brother, Can You Spare a Paradigm?” event, says the TEDxWestHollywood blog.

The takedown was only a couple of weeks before the April 14 event (and after they had spent more than a year preparing), the blog says.

In an email to Suzanne Taylor, the organizer of TEDxWestHollywood, a representative of TED outlined the objections: “And when… read more

Researchers in the Sheffield Centre for Robotics, jointly established by the University of Sheffield and Sheffield Hallam University, are programming a group of 40 robots.

The researchers have demonstrated that the swarm can carry out simple fetching and carrying tasks, by grouping around an object and working together to push it across a surface.

The robots can also group themselves together into a single… read more
