Computers to be used to find blueprint for new influenza drug

...nk of flu as just a nasty illness which puts us in bed for a few days. But some outbreaks can cause death on a large scale ?the world-wide outbreak in 1918 killed more people than the First World War itself. We may now be facing another flu outbreak, this time originating from chickens in Asia. “If we a...

New studies suggest airborne SARS transmission is possible

...ient was staying became infected. Proximity to the bed of the first case seemed to be strongly linked with incidence of infection-two-thirds of patients in the same bay and half of patients in an adjacent bay were infected with SARS, while only 18 percent of patients in distant bays were infected. The H...

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

...ual decline would have had to have a very slippery bed to maintain its continuous flow, Waddington said, and it appears the ice flowed vigorously despite being relatively thin. One major implication of the research, he said, is that it disputes the theory that West Antarctic ice streams retreated when t...

Tiny scaffolding allows stem cells to become working fat cells

...nt. The researchers' focus on fat cells as a test bed for this approach to cell growth offers important medical potential. While experts once thought a persons number of fat cells was set at birth, they now know individuals can either lose existing fat cells or grow new ones. And aside from the implicat...

Sexual cooperation: Mating increases longevity in ant queens

...ple, by traumatic inseminations (as in the case of bed bugs) or by the transfer of toxic seminal fluids (as in the case of the fruitfly Drosophila). These manipulations are beneficial to males because, for example, they reduce female re-mating probability or boost their fecundity directly after mating, b...

Robot-based system developed at Carnegie Mellon detects life in Chile's Atacama desert

... life in this harsh region, which serves as a test bed for technology that could be deployed in future Mars missions. "Our life detection system worked very well, and something like it ultimately may enable robots to look for life on Mars," said Alan Waggoner, Atacama team member and director of the Mol...

World-first technology enables study of ancient bacteria

...estigate sustainable energy sources from the ocean bed by isolating ancient high-pressure bacteria from deep sediments. Scientists and engineers at Cardiff University are investigating bacteria from deep sediments which despite high pressures (greater than 1,000 atmospheres), gradually increasing temper...

Discarded placentas deliver researchers promising cells similar to embryonic stem cells

...ntly available embryonic stem cell lines require a bed of mouse cells, traces of which can end up in each new generation of stem cells. Amniotic epithelial cells, on the other hand, create their own feeder layer, with some cells choosing to spread out at the bottom of the culture dish thereby giving thos...

Researcher says flu responders can learn from 1918 epidemic

... Monday, developed a headache Monday night, was in bed Tuesday and Wednesday, and was dead by Thursday," he said. "Some went peacefully, through pneumonia, which they called the 'old man's friend' because it provided an easy passage. Others weren't so lucky." Many others ?ironically, the typically he...

Because of bioaccumulation in the aquatic food chain, though, elevated concentrations of radiocaesium were found in fish from lakes as far away as Germany and Scandinavia. Comparable levels of radiostrontium, which conc...

Pillows - a hot bed of fungal spores

...llergic tendencies. Constant exposure to fungus in bed could be problematic. It can also get into the lung cavities created by tuberculosis which affects a third of the world's population, causing general ill-health and bleeding in the lung, as well as causing a range of plant and animal diseases. Dr G...

Travelers can avoid jet lag by resetting their body clocks

If they did this for the number of days equivalent to the number of time zones crossed, then they should be completely adjusted to the new tim...

Alleged 40,000-year-old human footprints in Mexico much, much older than thought

...a layer of volcanic ash deposited in a former lake bed now exposed near a reservoir outside Puebla. Its dating techniques returned a date of 40,000 years ago, in contrast to the oldest accepted human fossil from the Americas, an 11,500-year-old skull. This makes the rock "one of the most important areas ...

Botox could help target resistant tumors for treatment

...ategies that transiently opened the tumor vascular bed to alleviate tumor hypoxia. "Hypoxia is a source of resistance to radiotherapy, and is a determining factor in the poor prognosis of tumors to cytotoxic treatments," said Gallez. "Botulinum toxin could lead to inhibition of contractions of tumor ves...

Stem cell transplants improve recovery in animal models for stroke, cerebral palsy

If somebody can go from a wheelchair to a cane that is a big improvement, that is how we look at it," Dr. Hess said. Adult animals were tested ...

Pesticides in the nation's streams and ground water

Concentrations of these compounds in fish declined following reductions in their use during the 1960s and elimination of all uses in the 1970s and 1980s, and continue to slowly decline. Just as notab...

Chocolate, wine, spicy foods may be OK for heartburn, Stanford study finds

Although there is no evidence that ceasing consumption of the suspect foods will reduce heartburn, some of the st...
