Scientists identify 36 genes, 100 neuropeptides in honey bee brains

...ot have been measured because they were present at too low a level to be detected, Sweedler said. Others may have been missed because they are present only during particular developmental stages. Future work will no doubt find and confirm more of the brain's peptides. "The potential of our blended tech...

Obesity levels in US are grossly underestimated

...stimates of obesity in individual states have been too low, by more than 50%. Their study, which corrects for misreporting in those surveys, appears in the May 2006 issue of the Journal of the Royal Society of Medicine. Obesity is one of the leading causes of morbidity and mortality, causing some 2.6 m...

The recent ceasefire between the government of Nepal and the Maoists allowed us to enter the area and conduct a study ...

UGA scientists engineer root-knot nematode resistance

...has spent 20 years studying a worm-shaped parasite too small to see without a microscope. His discovery is vastly bigger. Hussey and his research team have found a way to halt the damage caused by one of the world's most destructive groups of plant pathogens. Root-knot nematodes are the most economicall...

Health authorities must therefore consider all the methods that might control the spread of the virus. With the increase in international travel that has taken place, the virus c...

New strategy developed to combat West Nile Virus

The situation, he adds, is much more complex. "In some cases, rain can ac...

He said the team will now examine the rats' bones at the cellular level "to see what caused that improvement in the bone." "A reduction in bone density is caused when there is an increase in oxidants. In these studies,...

Einstein researchers take the pulse of a gene in living cells

...ilarly, a cell needs the gene to be turned on--but too much activity at the wrong time can be a problem, so the solution is to have small bursts of activity." Still to be discovered, says Dr. Singer, is how the pulsing mechanism itself is controlled. In addition, these findings pertain to developmental ...

UCLA study finds same genes act differently in males and females

...One gender may metabolize the drug faster, leaving too little of the medication in the system to produce an effect." "At the genetic level, the only difference between the genders is the sex chromosomes," said Drake. "Out of the more than 30,000 genes that make up the human genome, the X and Y chromoso...
