Researchers identify protein crucial for survival of Lyme-disease bacterium

...k gut, Dr. Norgard said it appears that changes in temperature and acidity signal the bacteria that the nutrient is present, triggering the bacteria to replicate in large numbers and migrate to the tick's salivary glands, where they are transmitted into animals or humans during the tick's feeding process. The en...

Pulsating ultrasound enhances gene therapy for tumors

...rough long and continuous exposures that raise the temperature inside cancerous cells, effectively "cooking" them. Under a technique introduced by King C.P. Li, M.D., M.B.A., from the National Institutes of Health (NIH), short pulses of HIFU can be used to prevent exposed tissue from becoming too hot and damaged...

...r, or how species may be affected by variations in temperature and currents. To illustrate, one can quickly see changes in the abundance and distribution of Atlantic Cod over the past 30 years without poring through pages of data. To see the type of visual analysis the website can offer at this time, follow thi...

Researchers discover molecular mechanism that desensitizes us to cold

... cold and from that to expand our understanding of temperature regulation," said Dr. Logothetis. "Additionally, because the region of this receptor that interacts with PIP2 is found in many similar membrane proteins, we now have a new lead in investigating regulation of the many functions in which these proteins...

LUCA technologies confirms real-time methane generation

...and carbon dioxide. Thermatoga also thrive in high temperature environments, such as those found in sub-surface oil wells. "Oil within the Monument Butte field has a waxy composition that may facilitate the strong real-time methane generation we see at this site," commented Mr. Pfeiffer. "If so, then areas with...

New research indicates a 'troubled' greenhouse is brewing

.... "At that time, Wyoming warmed from a mean annual temperature of some 55 degrees to a summer-like 65 degrees Fahrenheit. Rainfall in Utah jumped from 16 inches per year to 26 inches per year. As a result, sagebrush deserts of the western U.S. were transformed into sub-humid woodlands." Retallack agrees with pr...

Ice core 'dipstick' indicates West Antarctic ice has thinned less than believed

...tract an isotope record that provided a picture of temperature and snowfall patterns near Siple Dome. The layers get thinner and thinner with depth, as more ice and snow piles up. But the thinness of the layers deposited near the end of the Last Glacial Maximum indicate the ice also was being thinned by ice stre...
