Scientists get best look ever at water-life connection

... there is no real controversy -- everybody is just looking at the same answer from different angles," he added. The answer, revealed in Zhong's lab: water molecules do move fast on their own, but they slow down -- to a speed midway between the nanosecond and picosecond scale -- to connect with proteins. Zh...

Emergency contraception fails to halt abortions

...regnancy. Professor Glasier writes: "If you are looking for an intervention that will reduce abortion rates, emergency contraception may not be the solution and perhaps you should concentrate most on encouraging people to use contraception before or during sex, not after it."...

Caterpillars tell us how bacteria cause disease

...virulence' factors in insect pathogens. Instead of looking at the whole genome ?which codes for the entire bacteria, Dr Waterfield's team fragment the genome and insert different genes into a harmless laboratory bacterium which they then insert into caterpillars and other invertebrates to study their immune ...

Microbe fixes nitrogen at a blistering 92 C

...ean off fixed nitrogen completely. An unimpressive looking sphere of a microbe, FS406-22 is able to grow with gaseous nitrogen as its sole source of nitrogen at temperatures ranging from 58 to 92 C, with the fastest growth at 90 C. The genetic analysis shows FS406-22 as having one of the deepest-rooted ge...

Proteins anchor memories in our brain

Tissue is already damaged, antigen expression is ramped up and the immune response is spreading to other self-antigens," Anderson said. "If we can also train our focus on the thymus, where we know at least some of th...

Autoimmune disease triggered if T cells miss a single protein early on

China's environmental challenges

Frontier's Finishing Lines columnist Katherine Ellison highlights Goldman Environmental Prize Award winner Yu Xiaogang, a C...

A wolf in sheep's clothing: Plague bacteria reveal one of their virulence tricks

...th another protein on the host cell's membrane. By looking at the crystal structure of this protein-protein complex, Prehna discovered that the configuration looked just like one formed by some of the host's own signaling proteins. And it's this mimicry, he found, that leads to a signaling shutdown and dereg...

Affymetrix 500K array used to identify memory gene

...nts of people with good memory vs. poor memory and looking for the genetic variations consistently present in one group, but not the other. They then validated their discovery by replicating the Kibra gene finding in two separate and distinct groups of subjects. "This memory study is a perfect example of ...

Blue eyes -- A clue to paternity

... you request a paternity test, spend a few minutes looking at your child's eye color. It may just give you the answer you're looking for. According to Bruno Laeng and colleagues, from the University of Tromso, Norway, the human eye ...

On the golf tee or pitcher's mound, brain dooms motion to inconsistency

...ical phenomenon, as had widely been thought. After looking at neural activity and muscle activity, the Stanford researchers concluded that less than half the reason for inconsistency in movement lies in the muscles. "This is the first study to successfully record neural activity during the planning period ...

Study offers window into human behavior, brain disease

...ghboring neurons in the anterior cingulate cortex, looking specifically at brain tissue from three sets of deceased patients -- seven who had no neurological disease, five who had Alzheimer's disease and seven who had frontotemporal dementia. The results were striking. In frontotemporal dementia, there wa...

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

... we can only really study what happened to them by looking at microfossils because these little critters are everywhere at all times. In just a pinch of sediment we can tell you the age, the prevailing climate, the environment in which it was deposited and what happened. It's remarkable." What the microfos...

Detecting explosives with honeybees

...e used to identify the presence of explosives. By looking at such attributes as protein expression, the team sought to isolate genetic and physiological differences between those bees with good olfaction and those without. They also determined how well bees could detect explosives in the presence of potent...

Scientists work to identify genes that contribute to early heart attack risk

...ientists will screen tissue samples from the study looking for genetic variants that may predispose individuals to develop early atherosclerosis. "Perhaps the most remarkable thing about this study is the large number of genetic variants that we’re going to study," said Herrington. "Using special technolo...

...s. "That made it very likely that the gene we were looking for requires light to be activated." "By identifying master genes that were activated by light, Adam was able to pinpoint the gene that controls the formation of anthocyanins in apples, and we found that in green apples this gene is not expressed a...
