Genetic factors are linked to fever following smallpox vaccination

... Jr., MD, of Vanderbilt University Medical Center, echoes Dr. Stanley’s sentiments that the findings represent an important preliminary step in understanding the variations in host responses to vaccines, and notes that further studies will need to replicate these findings, and to test other vaccines.

Mice with a migraine show signs of brain damage

...y who has treated thousands of headache sufferers, echoes Nedergaard’s call for a greater emphasis on prevention. “It’s astounding just how many migraine sufferers do not see a doctor and are not on a medication to prevent a recurrence,?said Friedman, professor of Ophthalmology and Neurology. “It’s estim...

An ancient bathtub ring of mammoth fossils

...wis area at elevations of 600 to 1,000 feet, which echoes the distribution of boulders that originated from far away—so-called erratics—and rafted in on icebergs. The evidence suggests that these elevations mirror the typical water depths when Lake Lewis and that larger floods and deeper waters, up to 1,200...

UTSA researchers examine effects of global warming on Antarctic

...ea ice sheets in the Arctic due to global warming echoes what many in the scientific community have been saying for years. Now researchers at The University of Texas at San Antonio's Department of Earth and Environmental Science are turning their attention to the South Pole to find out if global warming i...

Satellites shed light on global warming

... to Earth per second then recording how long their echoes take to bounce back to the satellite platform. The sensor times its pulses' journey down to under a nanosecond to calculate the distance to the planet below to a maximum accuracy of two centimetres. ESA has had radar altimeters in orbit since July 19...

Are genomic technologies the answer to world hunger?

...national Potato Centre (CIP), Dr. Roger Cortbaoui, echoes these arguments saying there is a need to construct, "useful partnerships and networks including with the private sector" in an industry where basic research is dominated by public funded research centres. Others argue that even greater private-publ...

New moth variety disarms plants guarded by selenium

...some insects, and that such adaptation potentially echoes in the food web as other predators and parasites may in turn evolve to deal with high levels of the toxic element. The findings, reported by Elizabeth Pilon-Smits of Colorado State University and colleagues there and at the University of California, ...

UC Riverside psychologist explores human perception, finds 'wow factor'

...determine the locations of objects by listening to echoes as noise bounces off them. Other test subjects have used room echoes to figure out where they are on campus -- blindfolded. Rosenblum's research explores speech, faces ...

Bats use touch receptors on wings to fly, catch prey, study finds

...environment by emitting calls and listening to the echoes that return from various objects. Zook believes the touch-sensitive receptors on bats' wings work in conjunction with echolocation to make bats better, more accurate nocturnal hunters. Echolocation helps bats detect their surroundings, while the tou...

Energy management in cells may hold key to cancer defense

...t before you can make truly significant advances," echoes Witters "It's like poker; not only do you need to know what each card signifies individually, but you must have an understanding of how they play off each other in order to win." In addition to cancer-fighting potential of AMPK regulation, the enzy...

A probe, not an echo

...sound waves are broadcast into the tissue, and the echoes produce an image of the reflecting interfaces ?that is, the sound transmitter and the receiver are both on the same side of the sample. However, only a tiny fraction of the transmitted sound comes back as echo on soft tissues, while a much larger fr...
