BlogNeurons

In research with mice at UT Southwestern Medical Center, a compound dubbed P7C3 enhanced production of new neurons in the hippocampus, a brain area involved in learning and memory.

It could also increase birth and survival of new neurons in older rats, according to statement by UT Southwestern Medical Center. The animals also had improved memory: they could better remember the location of a platform submerged in water,… read more

A Chinese Challenge to Intel

September 2, 2008

Chinese researchers have unveiled details of Godson-3, a scalable microprocessor with four cores (work in parallel) that they hope will bring personal computing to most ordinary people in China by 2010, with an eight-core version in development.

A Chip That Can Transfer Data Using Laser Light

September 17, 2006

Intel and University of California, Santa Barbara researchers plan to announce on Monday that they have created a silicon-based chip that can produce laser beams. The advance will make it possible to use laser light rather than wires to send data between chips.

Chip makers may be able to put the high-speed data communications industry on the same curve of increased processing speed and diminishing costs (Moore’s law) that… read more

A chlorophyll-based phototransistor

Chlorophyll_transistor

Shao-Yu Chen at the Institute of Atomic and Molecular Sciences in Taiwan and associates have incorporated chlorophyll into graphene transistors to make light-activated switches, MIT Technology Review reports.

The new phototransistor design consists of two silver electrodes connected by a sheet of graphene. The graphene is then covered by a layer of chlorophyll using a method known as drop casting. .

This layer has a significant influence… read more

Max Planck Institute (MPI) for Medical Research scientists are developing a complete circuit diagram of the brain of the mouse using an electron microscope to make fine extensions of almost every single neuron visible.

Most axons are less than one micron thick, some even smaller than 100 nanometers. “The electron microscope is the only microscope with a high enough resolution to enable individual axons lying next to each other… read more

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

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 model of an anticancer nanoparticle

IBM's Blue Gene supercomputer uncovers a novel drug interaction site
September 7, 2012

ibm_nanoparticles_cancer

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

April 9, 2012

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
