Soils offer new hope as carbon sink

...bon byproduct of a process called pyrolysis, which involves heating green waste or other biomass without oxygen to generate renewable energy. Tim Flannery, Australian of the Year and renowned scientist, conservationist, writer and explorer, is a major advocate of agrichar and pyrolysis. In The Bulletin ...

Threats to wild tigers growing

...onservation of the species will need planning that involves religious and civic leaders as well as national and local governments. International cooperation among nations that harbor the animal will also be essential. Dinerstein and his coauthors conclude by recommending that these countries appoint "tiger am...

Undergraduate research shows leaderless honeybee organizing

Undergraduate education generally involves acquiring “received knowledge” – in other words, absorbing the past discoveries of scholars and scientists. But University of North Carolina at Charlotte senior biology major Andrew Pierce went beyond the textbooks and uncovered something previously ...

College students who pull 'all-nighters' and get no sleep more likely to have a lower GPA

A common practice among many college students involves "pulling all-nighters", or a single night of total sleep deprivation, a practice associated with lower grade-point averages compared to those who make time for sleep, according to a research abstract that will be presented Wednesday at SLEEP 2007, th...

Microbes at work cleaning up the environment

...ralization mechanism that is unexpected because it involves the bacteria excreting proteins for nanoparticle aggregation away from the cells,” said Peter Weber, one of the LLNL authors of the paper appearing in the June 15 edition of the journal Science. Weber and LLNL colleague Ian Hutcheon used LLNL’s Na...

Runners -- Let thirst be your guide

...option, and that is undertaking a sweat test. This involves recording a person’s weight digitally, then running on a treadmill for an hour and recording their ending weight after toweling off the body sweat. “Most people don’t know how much they really sweat while exercising, but this simple test can tell you...

UCF nanoparticle offers promise for treating glaucoma

...a central role in causing glaucoma. The disease involves abnormally high pressure of the fluid inside the eye, which, if left untreated, can result in damage to the optic nerve and vision loss. High pressure occurs, in part, because of a buildup of carbon dioxide inside the eye, and the compound blocks th...

Genome of Clostridium botulinum reveals the background to world's deadliest toxin

...by Cdiff — long-term interaction with hosts, which involves evading the immune system and countering antibiotics — to the single-minded opportunistic approach of C. botulinum....

'Smart' mice teach scientists about learning process, brain disorders

...r maze and remembering that being in a certain box involves a mild shock. Equally important, Dr. Bibb said, when a situtation changed, such as the water maze being rearranged, the engineered mice were much faster to realize that things were different and work out the new route. Dr. Bibb cautioned that whi...

Treating HIV in war zones -- Public health emergencies need rapid advice from WHO

...o years or more to develop. The laborious process involves convening experts who search for and appraise all the relevant research literature, and who meet several times before making treatment recommendations. Such a time frame is clearly not practical in an emergency situation. Holger J. Schünemann and...

First confirmed common genetic risk factors for breast cancer

...ct on breast cancer risk. "Breast cancer likely involves many risk genes, and each gene only confers a moderate risk for disease," Dr. Liu explained. While the findings of the international research collaboration hopefully will fuel the development of more effective ways of preventing and treating breas...

Mice with a migraine show signs of brain damage

...an aura. CSD is an electrical event that initially involves a burst of intense activity among the neurons on the surface of the brain, followed by a gradually spreading wave of suppressed brain cell activity. Many scientists believe that the phenomenon contributes to injury from stroke and from traumatic b...

US control strategies may make flu epidemics worse, UCLA study shows

...ologist, is the human factor. The human factor involves two biological characteristics, "memory and how adaptable people can be," Blower said. "These characteristics drive human behavior." Blower and her group used people's attitudes toward the seasonal flu to construct their model. With seasonal flu, ...

First clinical trial of gene therapy for childhood blindness

...on future treatments for eye disease. The trial involves adults and children who have a condition called Le... The new technique that will be used in the trial involves inserting healthy copies of the gene into the cells of the retina to help them to function normally....

New Brandeis research sheds light on memory by erasing it

... importance may be conditions like epilepsy, which involves synapses that have become overly strengthened. The new research shows how synapses can be weakened by attacking memory molecules. Lisman's lab plans further research to better understand what happens to the CaMKII after it is attacked. By using f...

From the deep -- Researchers find new species of sea anemone

...cting deep-sea creatures is a tedious process that involves a lot of high-tech equipment like underwater video cameras attached to remotely operated vehicles (ROVs). Deep sea ROVs are also equipped with robotic arms and suction devices that are used to collect species. "It's like a submarine that's manned ...

Latent memory of cells comes to life

... normally arise by a slow and gradual process that involves natural selection operating over many generations. Sometimes however, dramatic and very sudden changes are observed in one individual in the absence of any kind of change to the DNA. This happens in fact in all of us as our body develops: cells w...

Peanut allergies overstated, study finds

...uts when they took a peanut challenge. A challenge involves eating peanuts in a hospital environment. "Diagnostic tests for peanut allergy have poor sensitivity and specificity," the paper concludes. "Previously described diagnostic cut-off levels do not have general applicability." Reasons for this may...

Intelligent materials to regenerate bone tissue

...without any serious repercussion. Another exigency involves the carrying out of the mechanical functions of the damaged bone while the desired regeneration takes place. The solutions have to be capable, moreover, of remedying particularly serious damage, such as those due to congenital deficiencies, degene...

Study examines genetic risk factors for Alzheimer's disease

...This is one of the largest studies of its kind and involves many Welsh families " said Professor Julie Williams. “It is by virtue of the support given to us by Alzheimer's sufferers and their carers that we are able to understand factors involved in the disease process. Many genes will be linked with Alzheim...
