A Clearer Picture of Cancer

November 24, 2008

A new 3-D near-infrared imaging system that uses an ultrafast camera and femtosecond laser to capture unscattered light has been developed by researchers at the Institute for Biological and Medical Imaging at the Helmholtz Center and Northeastern University.

It’s been used to create richer, higher-resolution images of the molecular workings of lung cancer in mice, and with further development, it might be used to study disease in thicker tissues… read more

A closed Android-based network to study cyber disruptions and help secure hand-held devices

October 4, 2012

Sandia builds self-contained, Android-based network to study cyber disruptions and help secure hand-held devices

As part of ongoing research to help prevent and mitigate disruptions to computer networks on the Internet, researchers at Sandia National Laboratories in California have turned their attention to smartphones and other hand-held computing devices.

Sandia cyber researchers linked together 300,000 virtual hand-held computing devices running the Android operating system so they could study large networks of smartphones and find ways to make them more reliable and… read more

Fujitsu is shipping an LCD-based electronic reader called FLEPia in Japan next month that displays vivid color, a first in the industry.

A common cortical organization among mammals

November 17, 2011

Human Mouse

A new study by researchers at the University of California, San Diego School of Medicine and colleagues using magnetic resonance imaging data of 406 adult human twins affirms the long-standing idea that the genetic basis of human cortical regionalization — the organization of the outer brain into specific functional areas — is similar to and consistent with patterns found in other mammals, indicating a common conservation… read more

A common link among fire, floods, food riots: extreme weather

September 8, 2010

Deadly riots in the streets of Mozambique over sharply higher food prices have left 13 dead. Anger is growing in Egypt and Serbia as well. Panicked Russian shoppers have cleared the shelves of staple grains. And the devastating floods that have left as many as 10  million Pakistanis homeless are also raising concerns about the country’s ability to feed itself.

A series of isolated disasters? Not… read more

A Company Looks to Wean Computers Off the Wires

September 19, 2005

Airgo Networks’ high-speed wireless networking system, True MIMO, operates at as much as 240 megabits a second, surpassing Wi-Fi and Ethenet rates.

It will allow for high-resolution digital video distribution in the home.

A ‘compound eye’ on light sent from galaxies 10 billion years ago

October 12, 2012

At ESO’s Very Large Telescope (VLT) in Chile they are about to fit a new instrument called KMOS that can record the light from 24 galaxies simultaneously.

KMOS has 24 robotic arms tipped with gold-plated mirrors that can be trained on a different galaxy — each arm has almost 200 facets making them rather like an insect’s compound eye. Light from these mirrors is channelled… read more

A computational algorithm for fact-checking

Yet another "computers can't..." myth busted
June 19, 2015

truth scores-ft

Computers can now do fact-checking for any body of knowledge, according to Indiana University network scientists, writing in an open-access paper published June 17 in PLoS ONE.

Using factual information from summary infoboxes from Wikipedia* as a source, they built a “knowledge graph” with 3 million concepts and 23 million links between them. A link between two concepts in the graph can be read as a… read more

Researchers have used computational modeling to precisely simulate how a drug inhibits a target enzyme known to spur cancer’s spread, capturing the interaction at the quantum-mechanical level, Technology Review reports.

They hope their work will uncover a way to specifically inhibit members of a whole class of cancer-linked proteins without causing as many side effects as existing drugs.

The authors showed that a buckyball molecule, which… read more

A computational model of human tissue

Computer scientists and biologists in the Data Science Research Center at Rensselaer Polytechnic Institute have uncovered a new computational model called “cell graphs” that links the structure of human tissue to its corresponding biological function.

The tool is a promising step in the effort to bring the power of computational science together with traditional biology to the fight against human diseases such as cancer.… read more

A computer interface that takes a load off your mind

Postdoctoral MIT researcher Erin Treacy Solovey and her team have designed Brainput, a system using a headband that recognizes when a person’s workload is excessive and automatically modifies a computer interface to make it easier.

The researchers used a lightweight, portable brain monitoring technology called functional near-infrared spectroscopy (fNIRS), which senses brain activitythrough the skull (no electrodes neeed).

Analysis of the brain scan data was then fed into a… read more

Researchers are developing pattern-analysis programs that can quickly examine hundreds of paintings to determine authenticity.

A computer-like brain mechanism that makes sense of novel situations

September 26, 2013

Indirection_glassbrain

Researchers at the University of Colorado Boulder have demonstrated that our brains could process new situations by relying on a method similar to the “pointer” system used by computers.

Pointers are used to tell a computer where to look for information stored elsewhere in the system.

For the study, the research team relied on sentences with words used in unique ways to test the… read more

A computer-vision algorithm that can describe photos

Machine-learning takes computer vision to the next level with a system that can describe objects and put them into context. Coming soon, better visual search?

images with scenes ft

Computer software only recently became smart enough to recognize objects in photographs. Now, Stanford researchers using machine learning have created a system that takes the next step, writing a simple story of what’s actually happening in any digital image.

“The system can analyze an unknown image and explain it in words and phrases that make sense,” said  Fei-Fei Li, a professor of computer science and director of the… read more

A computerized house that generates as much energy as it uses

NIST unveils net-zero energy residential test facility to improve testing of energy-efficient technologies

NIST Net Zero Energy Residential Test Facility

The U.S. Commerce Department’s National Institute of Standards and Technology (NIST) has unveiled a laboratory in the form of a typical suburban home, designed to demonstrate that a family of four can generate as much energy as it uses in a year.

The two-story, four-bedroom, three-bath “Net-Zero Energy Residential Test Facility“ was built to U.S. Green Building Council LEED Platinum standards — the highest standard for sustainable… read more
