Harmful Algal Blooms monitored from space in Chile

...ger caged fish such as salmon that cannot flee the affected area. In the case of shellfish, such as mussels, toxins from the blooms accumulate in their body tissues and pose serious health risks for humans when consumed. For instance, in 2002 an HAB outbreak in Chile was responsible for 73 paralytic poiso...

Gene therapy injected into the brains' of mice with Huntington's disease

...known to be destined to get HD. "Each child of an affected parent has a 50 percent risk for inheriting the disease. Genetic testing can identify mutated gene carriers destined to suffer from HD. Unlike other neurodegenerative disorders, identification of the genetic markers provides a unique opportunity to ...

Bird brains shrink from exposure to contaminants

...song production and courtship behaviour--were most affected by DDT," said Iwaniuk. "Song production is extremely important in attracting a mate or to mark out a territory. "The issue is not that DDT is killing these robins but if they are growing up in this one area and then move to another, they won't be a...

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

... prevalence. They found that an outbreak is barely affected when hunting occurs between mating and birth season while an outbreak lessens when hunting occurs during the birth season. An outbreak increases dramatically when hunting occurs between the birth season and the next mating season. The effect can be...

New research examines genetics of successful aging

...re associated with successful aging, some of which affected men or women, but not both. "Historically women have lived longer than men on average, the prevalence of numerous serious diseases differs in men and women, and there are important differences in age-related physiological changes that occur between t...

Heal thyself: Systems biology model reveals how cells avoid becoming cancerous

...another group of genes whose expression is sharply affected by DNA damage, but which appear to play no role in repairing the damage itself. Ideker's team uncovered a tangled network of interactions of 30 transcription factors with more than 5,000 yeast genes. A transcription factor is a protein that, either ...

Breaks in hibernation help fight bugs

...almonella in European ground squirrels, and how it affected their torpor patterns in relation to temperature. Microbial growth depends on temperature. Most bacteria grow faster when it is warm and much slower when it is cold. For animals exposed to Salmonella, which multiplies rapidly in warm temperature...

Tiny airborne particles are a major cause of climate change

...ation on cloud cover. Radiation absorption is less affected by meteorology, so if the skeptics are right and meteorology is the main influence, then the correlation between aerosol absorption and cloud cover should have been seen in only a few circumstances. But this was not the case. They observed the dualit...

Study finds that a woman's chances of having twins can be modified by diet

... the first time that the chance of having twins is affected by both heredity and environment, or in other words, by both nature and nurture," said Dr. Steinman. These findings are similar to those observed in cows by other researchers, namely that a woman's chance of having twins appears to correlate directly...

Virus has 'catastrophic' affect on red squirrels, research shows

...rongholds in Scotland and Italy that have not been affected by the virus. The team looked at how far red squirrels had retreated on a landscape scale, and found the annual distance was 76 square kilometres in Cumbria and 96 sq km in Norfolk. In contrast, the annual retreat in Italy was just 3.6 sq km and 4...

Stanford snake venom study shows that certain cells may eliminate poison

It all depends on the balance between the positive and negative effects of the mediators released by mast cells in response to a particular venom,...
