Revealing the machinery underlying the 'plastic' juvenile brain

...perties of the young brain enable it to so adeptly wire itself to adapt to experience—a quality known as plasticity. The extraordinary plasticity of the young brain occurs only during a narrow window of time known as the critical period. For example, children deprived of normal visual stimulation during a...

T-ray breakthrough could make detecting disease far easier

...the researchers found that although ordinary metal wire would not guide T-rays very well, if a series of t... much more effectively. If such a corrugated metal wire is then tapered to a point it becomes possible to very efficiently transport radiation to a point as...

Mapping the protein world

...ng a three-dimensional model of a protein required wire models, screws, bolts and years of tedious calculations by hand. Today macromolecular models are built by computers ?thanks to sophisticated software and in particular a package called ARP/wARP. Developed by Victor Lamzin at the Hamburg Outstation of...

Carnegie Mellon researchers discover key deficiencies in brains of people with autism

... callosum, the white matter that acts as cables to wire the parts of the brain together. This latest research shows for the first time that the abnormality in synchronization is related to the abnormality in the cabling. The results suggest that the connectivity among brain areas is among the central prob...

Microbes transform 'safest' PBDEs into more harmful compounds

...n says. PBDEs are used in televisions, computers, wire insulation, upholstery and many other products containing plastic and foam. If these products overheat, PBDEs release atoms called bromines that sap oxygen from the air, preventing a fire. Over time, PBDE’s can leach into the air, soil and sediment, ...

Surprise finding for stretched DNA

...ameter," said Bustamante. "This enables the outer wire to wrap a larger number of times over the length of the rod." The twist-stretch coupling results demonstrated by Bustamante and his collaborators holds important implications for how DNA-binding proteins are able to recognize their target sites alo...

Corn waste potentially more than ethanol

... These electrons travel to the anode and flow in a wire to the cathode, producing electrical current. The water in the fuel cell donates positive hydrogen atoms that combine with the electrons and oxygen to form water. The microbial fuel cells were inoculated with domestic wastewater and a nutrient me...

How plants avoid feeling the burn

... it's much like trying to measure the current of a wire found in an everyday household appliance, only in this case, the "wiring" is a miniscule 2.8 nanometers long and less than a single nanometer thick, or about 10,000 times smaller than the width of a human hair. One measurement problem is that carot...

Creating a window on 'oceans in motion'

...pecies do we want to track and exactly where do we wire up the world to create an effective global system of watching the oceans in motion," says Dr. O'Dor. Continental shelves average about 80 km (50 mi) wide, and the edge of the shelf occurs at an average depth of about 200 m (660 ft), where it falls s...

New University of Toronto research a 'pore' excuse for engineering

..., computer chip manufacturers have insulated their wire connections with silica glass, preventing them from coming into contact and interfering, with each other. But the PMO film described in this study acts as a better insulator and would take up far less room, allowing components to shrink even further....

ASU researchers 'wire' DNA to identify mutations

... "We have developed a technology that allows us to wire single molecules into an electrical circuit," said Tao, professor of electrical engineering in the Ira A. Fulton School of Engineering and also a researcher in the Center for Solid State Electronics Research. "We can now directly read the biological...

Research: Snails were overlooked contributors to marsh destruction

...ots of healthy marsh, then enclosed the plots with wire mesh, preventing snails from reaching the grass. They put enclosures in the path of expanding die offs, as well as in remnants of healthy marsh. After 14 months, the patches were "robust and green" compared with denuded areas where snails moved throu...

Brainstem blocks pain to protect key behaviors

... NPP, studied adult male rats in containers with a wire mesh floor that enabled them to deliver radiant heat to one hind paw. The heat caused no damage but was annoying enough to make the animal withdraw that paw within seconds. When the rats ate, however, they postponed retracting the heated paw for...

Team led by Carnegie Mellon University scientist finds first evidence of a living memory trace

...r-old proposition that "neurons that fire together wire together," thereby strengthening their connections. According to the theory, a stimulus activates some neurons while inhibiting others. Once this stimulus is removed, traces of that excitation/inhibition pattern ?so-called Hebbian reverberations ?sho...

Cyberkinetics, Case to develop system to help restore extremity function

...esponsible for movement, the motor cortex. A small wire connects the sensor to a pedestal that is placed on the skull, extending through the scalp. An external cable connects the pedestal to a cart containing computers, signal processors and monitors that enable the study operators to determine how well ...

Biotechnology's newest chemical tool

It's electric: Cows show promise as powerplants

... the movement of electrons across the resistor and wire that connects the two electrodes, creates electrical current. The anode chamber was filled with rumen fluid and cellulose, which served as a food source for the microorganisms. Cellulose is plentiful on most farms, as harvesting usually leaves behin...

Purdue researchers use enzyme to clip 'DNA wires'

Grizzlies set to invade high Arctic?

... mud. And from the cabin's outside walls and a guy wire attached to the roof they collected two intriguing brown hairs. These were sent for analysis to Wildlife Genetics International Inc. in Nelson, British Columbia, one of the world's premier bear DNA labs. The result: the genetic analysis pointed to a ...

Microbial fuel cell: High yield hydrogen source and wastewater cleaner

...solution. The electrons on the anode migrate via a wire to the cathode, the other electrode in the fuel cell, where they are electrochemically assisted to combine with the protons and produce hydrogen gas. A voltage in the range of 0.25 volts or more is applied to the circuit by connecting the positive p...
