Ultra low-dose estrogen shown safe for post-menopausal women

...effects. With a patch, you bypass the liver and go straight to the blood." Yaffe notes that since the WHI results were announced in 2004, "the field of estrogen research has been stymied. Hopefully, this study will start to turn the tide." ...

Stimulation of the semicircular canals can artificially control human walking and balance

...ied in a way that allowed a person who was walking straight ahead to be steered by "remote control" without her balance being affected. The findings are reported by Richard Fitzpatrick and Jane E. Butler of the Prince of Wales Medical Research Institute and the University of New South Wales, Australia, and Br...

Federal testing for mad cow disease a failure, law review editor says

...old English girl, for example, cried for two weeks straight and then began screaming before she died. His article is titled, "Food Safety vs. Promotion of Industry: Can the USDA Protect Americans From Bovine Spongiform Encephalopathy?" ...

3-D model reveals secrets of metastasis

... in virtual experiments and then he was able to go straight to test the predictions with these complicated 3D experiments. As a result, the sophisticated models of cell movement enhance our understanding of key biological processes, including metastasis."...

Iowa State researchers improving plastics made from corn and soy proteins

...gineering. Then he unfolded the model into a long, straight loop. That's what happens when researchers add some glycerin ?a byproduct of biodiesel production ?and some water to the molecule. And that's how biorenewable, biodegradable plastics can be made from the proteins in Iowa crops. But those aren't th...

'Mindless autopilot' drives people to underestimate food decisions

...in a bowl ate 134 fewer calories than those eating straight from the bag. Bank your calories: Skip the appetizers if you know you want to save room -- and enjoy -- the upcoming dessert. You'll also be more accurate at estimating the number of calories you consumed. Sit next to the slowest eater at the...

Far more than a meteor killed dinos

...ge impact hit and pushed them over the brink ?many straight to extinction. As for how the dinosaurs were affected, that's a bit harder to say specifically, since dinosaurs did not leave a lot of fossils behind to tell the tale. "Dinosaur fossils are few and far between," Keller said. "People love the di...

'Fruit fly dating game' provides clues to our reproductive prowess

...ge impact hit and pushed them over the brink ?many straight to extinction.

Researchers reveal mystery of bacterial magnetism

...ching for a specific altitude. If she only climbs straight up or down the mountain, she should find it more quickly. "But by observing how the bacteria moved away from oxygen that we added to their environment," reports Dr. McRae Smith, a member of the team while a postdoctoral researcher at NRL, "we direct...

How ants find their way

Ever wondered how ants find their way straight to the uncovered food in your kitchen? Now scientists have discovered how the humble wood ant navigates over proportionally huge distances, using just very poor eyesight and confusing and changing natural landmarks. The research could have significan...

New research to cut animal testing

...you can't ask human volunteers to take novel drugs straight from testing done in tube tests," said Dr Walmsley. "But if we can refine the pre-animal tests and increase people's confidence in them, then we will be able to reduce the number of chemicals that are tested on live animals." ...

U of M researchers invent 'flashy' new process to turn soy oil, glucose into hydrogen

...new process skips the biodiesel step and turns oil straight into hydrogen and carbon monoxide gases by heating it to about 1,000 degrees C. About 70 percent of the hydrogen in the oil is converted to hydrogen gas. Similarly, using a nearly saturated solution of glucose in water, the process heats the sugar so...

CSIRO imagery shows Outer Great Barrier Reef at risk from river plumes

...is is the first time they can be seen and analysed straight after the event as there are now more satellites imaging the Earth and CSIRO has invested in fast information delivery systems. The images answer many of the questions posed in the article 'Cattle, Crops and Coral: Flood Plumes and the Great Barr...

Swimming 'to the left' gets bacteria upstream, and may promote infection

...ard. Away from any boundaries, the cells swim in a straight line, but near a surface, opposing forces of flow and bacterial forward motion cause the bacteria to continuously swim to one side ?to the left." The study determined that swimming "to the left" is a hydrodynamic process that is fundamentally relate...

Walking molecule now carries packages

... the first to design a molecule that can move in a straight line on a flat surface. Now this team has found a ...n dioxide (CO2) molecules and carry them along its straight path. "Carrying a load slows the molecule down" explained Bartels. "Attachment of one CO2 molecul...

New study may show how to forestall a fatal, virus-caused immune-system meltdown

...eady have FDA approval,?Bowick said. “If we can go straight from discovery to drug candidates, that’s quite a big leap for us, and one that may be very helpful, since there’s really no incentive for drug companies to go out and develop new antiviral compounds for viruses that may or may not ever make it out o...

Paleontologists discover new mammal from Mesozoic Era

...ms. Its teeth are notable for the three cusps in a straight line on molars (thus known as a triconodont) for feeding on insects and worms. It has a long body, short and sprawling limbs and claws that were ideal for either digging or living on the ground. In addition to its unique ear structure, Yanoconodon...

UC Davis researchers use heated nanoprobes to destroy breast cancer cells in mice

...probes -- more than 10,000 can fit on the end of a straight pin -- into the bloodstreams of laboratory mice bearing human breast tumors. Once in the bloodstream, the probes began to seek out and latch onto receptors on the surface of malignant cells. Three days later, the team applied an alternating magnet...

Ancient genes used to produce salt-tolerant wheat

...y to find the durum variety with the ancient genes straight away, otherwise we might have been looking for years." The team used their knowledge of the two genes to construct molecular markers, which are now in use in CSIRO's wheat breeding program. A durum wheat variety as salt-tolerant as bread wheat is...
