Autistic brain has fewer neurons for processing emotion

...me, research has shown that the autistic brain has fewer neurons in an area related to emotion and social b...t surprising, therefore, that there are ultimately fewer neurons in the autistic amygdala," says Schumann. Schumann suggests different explanations: the a...

Global study shows all tobacco bad for the heart

...stopping smoking. Light smokers, those who consume fewer than 10 cigarettes a day, benefit the most. They have no excess risk three to five years after quitting. By contrast, moderate and heavy smokers of 20 or more cigarettes a day still had an excess risk of around 22 per cent, 20 years after quitting. ...

Researchers uncover new mechanism of tumor suppressor

... new diagnostic markers and cancer treatments with fewer side effects, will appear in two reports in the May 21 advanced online version of the journal Nature. The studies, led by Tatiana Kutateladze, PhD, an assistant professor in the UCDHSC Department of Pharmacology, and Or Gozani, MD, PhD, an assistant...

Tiny airborne particles are a major cause of climate change

...to form clouds and rain. A stable atmosphere means fewer clouds; fewer clouds mean less reflection of sunlight; less reflection of sunlight and absorption of radiation lea...

Life and death in the hippocampus: what young neurons need to survive

...eeks later, animals that received the virus showed fewer fluorescent neurons compared to mice injected with a benign virus lacking the shears, meaning fewer new neurons had survived originating from neural stem cells in which the NMDA receptor had been elim...

Viral hitchhiker inhibits Wolbachia bacteria's ability to proliferate

...al growth. Then they bred the wasps and confirmed fewer incidences of cytoplasmic incompatibility in relation to the reduced presence of the bacteria and increased presence of the virus. "We're excited about these findings because there is a great deal of interest in deciphering the genetic and cytolog...

New findings offer more complete view of breast cancer gene mutations in US population

...e 45. For BRCA2 mutations, researchers uncovered fewer predictors, and they had more modest effects. Among the breast cancer patients studied, the only significant predictors of a BRCA2 mutation were early age of onset (before age 45) in the patient herself or early onset of breast cancer in mother, sist...

UGA researchers find that hunting can increase the severity of wildlife disease epidemics

...ld animals to control disease outbreaks is simple: fewer animals should result in reduced transmission of disease. Hunting has been used to control badger populations in England, rabies in European foxes and chronic wasting disease in deer and elk populations in the American West. The researchers note that...

Invasive species alter habitat to their benefit

...g in these invaded areas also were different, with fewer classic wetland species, such as bulrushes, rushes, and sedges, and more typical land plants like grasses, asters, and goldenrods. Next, Farrer did transplant experiments to figure out whether the invaders were causing the changes she observed. She...

Researchers offer clues to how leaves patterns are formed

Researchers unveil strategy for creating actively-programmed anti-cancer molecules

...ated with the new compound developed significantly fewer metastases than those treated with other similar compounds or the antibody alone. These results, the study noted, were a "significant enhancement in the therapeutic efficacy" of the integrin antagonist directly attributable to the chemically programm...

Prozac's target revealed

...n of more specific treatments for depression, with fewer side effects, to be developed. The findings also lay the foundation for many studies of the factors that control how, when, and where new neurons are generated from stem cells in the brain. Such work could eventually lead to cell replacement therapi...

Transgenic goat's milk offers hope for tackling children's intestinal disease

...oliform bacteria in the small intestine, including fewer Escherichia coli (E. coli), than did the control group of young pigs that were fed milk from non-transgenic goats. Some strains of E. coli can cause severe intestinal illness. However, the kid goats fed lysozyme-rich goat's milk, had higher levels...

Prevention is the best option: fighting autoimmune diseases

... in humans and conventional methods could identify fewer than a third of the total number. The blood test we have developed allows us for the first time to accurately count thenumber of regulatory T cells in the body," says Assoc Prof Fazekas. The highly accurate identification and isolation of regulatory...

All the eggs in one basket

...h 20th century, most likely due the turtles eating fewer of the toxic sponges. The changing ratio of sponge species will ultimately affect the landscape of coral reefs. The scientists say more protection is needed for the sea turtle nesting sites. "Protecting more nesting beaches is not a politicall...

Choosy females make colourful males

...s: brightly coloured males from both species carry fewer parasites and are thus in better condition. Moreover, both species are adapted to different infection risks, which are associated with a difference in water depth and food choice. It is therefore in the females' interest to mate with their own males....

Gene discovery opens door to tackling disease

...said. "The benefit is that 'smart' drugs can mean fewer nasty side effects for patients as they target specific genes, not entire areas of the body." The find could also help researchers create blood tests to diagnose breast and prostate cancer. "A breakthrough in the techniques available to diagnose br...

Cutting calories slightly can reduce aging damage

... scientists found that feeding rats just 8 percent fewer calories a day and moderately increasing the animals' activity extended their average lifespan and significantly overturned the negative effects of cellular aging on liver function and overall health. An 8 percent reduction is the equivalent of a fe...

Where have all the butterflies gone?

...s present at this time in an average year, and far fewer individual butterflies than usual. For example, at Gates Canyon near Vacaville he counted 10 species and 43 individuals on April 18, 2006. At the same site on April 19, 2005, he counted 21 species and 378 butterflies. This winter's weather condition...

A rice future for Asia

However, an innovative project being launched this week in Thailand and the Philippines marks the start of a major new effort to encourage young Asians t...
