Dinosaur hearing, listening to muscle noise, quieter cubicles

...s approaches to making the machines quieter. A UK team (including Deborah Hall, MRC Institute of Hearing Research, Nottingham, d.hall@ihr.mrc.ac.uk ) will present an active noise control system that cancels out some of the sound from the machines. The system takes into account known properties of the M...

Spreading viruses as we breathe

...l a metre in the air. Professor Morawska and a team of QUT scientists have been studying the way droplets carring viruses are dispersed in the air when people speak, cough, sneeze and breathe. "The current belief is that if you are an arm's length away from someone you are protected from any viruse...

Decoding protein structures helps illuminate cause of diabetes

... protein structures. A few years ago, Zanni's team built the first device capable of designing infrared laser beams with a computer. The team has now simplified and speeded up the process with an automated version of the 2-D IR technique. As...

Implanting dopamine generators in brain cells obtains improvement in Parkinson's in monkeys

...ious study, published in 1999 by the same research team in the specialist journal, Neuron . The first nam...ated to last for at least a year. The research team concluded that the mechanism by which the implants in the striate area of the brain of dopamine-gene...

Iowa State scientists demonstrate first use of nanotechnology to enter plant cells

A team of Iowa State University plant scientists and mate...e of the particle with a chemical coating. "The team found a chemical we could use that made the nanoparticle look yummy to the plant cells so they would...

Scientists discover new life in the Antarctic deep sea

...ok place between 2002 and 2005. An international team from 14 research organisations investigated the seafloor landscape, its continental slope rise and changing water depths to build a picture of this little known region of the ocean. They found over 700 new species....

Do fruit flies have free will?

...isticated mathematical analyses, the international team of researchers showed for the first time that such...o adequately model fly behavior. Only after the team analyzed the fly behavior with methods developed by co-authors George Sugihara and Chih-hao Hsieh fr...

Growing nerve cells in 3-D dramatically affects gene expression

...fferences in gene activity. Hoffman-Kim and her team deployed high-powered microscopes to detect other differences. Cells cultured in 3-D had a rounder, more realistic shape, and their neurites ?spindly projections sprouting from the cell body ?were longer. "The cells in 3-D culture grew faster and ...

Hives ferment a yeasty brew, attract beetle pest

...tract the small hive beetle. Now, an international team of researchers has found that small hive beetles can detect some alarm pheromones at levels below that detected by honeybees. The beetles associate the alarm chemicals with a good food source and head for the hive. In Africa, where the small hive be...

Rare soft-shell turtle, nesting ground found in Cambodia

...d a further survey of the area by an international team of flora and fauna experts was planned for July 2007. The turtle survey team consisted of Cambodian Fisheries Administration staff and the Cambodian Turtle Conservation Team, a ...

Newly identified mechanism for silencing genes points to possible anti-cancer strategies

...y published online May 16 in the journal Nature, a team of scientists at The Wistar Institute and the University of California, San Diego, report identification of an important new gene-silencing mechanism, one that blocks the cellular machinery responsible for translating messenger RNA into proteins at s...

Study of protein folds offers insight into metabolic evolution

...ancient biochemistries," the authors wrote. The team used data from two international compilations of genetic and proteomic information: the metabolic pathways database of the Kyoto Encyclopedia of Genes and Genomes, and the Structural Classification of Proteins database. They combined these two data s...

Fused nasal bones helped tyrannosaurids dismember prey

... ability to bite deeply in the bone. Snively's team found that fused tyrannosaurid nasals were stronger than unfused carnosaur nasals. This extensive fusion increased the strength of such dinosaurs as the T. rex and helped them apply powerful bites that could splinter bone. With other carnivorous dino...

Switching genes to overdrive improves muscular dystrophy symptoms in mice

To sleep, perchance to dream: New insight into melatonin production

In the April 1 issue of G&D, a Korean research team led by Dr. Kyong-Tai Kim (Pohang University) describes how melatonin production is coordinated with the body's natural sleep/wake cycles. Melatonin is a hormone produced by the pineal gland in the brain, which helps to regulate our bodies' circadian...

Discovery of 'master switch' for the communication process between chloroplast and nuclei of plants

...ght become too great on the organism. A research team that includes Shai Koussevitzky, a research associate in the University of Nevada, Reno’s College of Agriculture, Biotechnology and Natural Resources, as well as Ron Mittler, associate professor of Biochemistry and Molecular Biology, has determined t...

City ants take the heat

...e effects of urban warming. Now, an international team of biologists, led by Michael Angilletta of Indiana State University, has shown that city animals have been affected by urban heat islands. These researchers discovered that ants within South America's largest city—São Paulo, Brazil—could tolerate he...

In Iran, cheetahs collared for the first time

An international team of scientists led by the Wildlife Conservation Soc... time the species has been handled by a scientific team in Iran and represents a unique new phase of WCS's long-term involvement in the country. The new col...

Deconstructing brain wiring, one neuron at a time

...e exactly which cells are connected to which. The team of Salk researchers sought to create a modified virus whose spread could be limited to a single synaptic connection. "The core idea is to use a virus that is missing a gene required for spreading across synapses but to provide the missing gene by ...

NIDA study identifies genes that might help some people abstain from smoking

...ge Uhl at NIDA’s Intramural Research Program and a team led by Dr. Jed Rose at the Center for Nicotine and Smoking Cessation Research at Duke University Medical Center.
