Brain inflammation may be friend, not foe, for Alzheimer's patients

.... O’Banion notes that some studies have found that taking medications to squelch inflammation, such non-steroidal anti-inflammatory drugs or NSAIDs, might help reduce a person’s chances of getting Alzheimer’s disease, while other studies, including a study of more than 2,100 people published in April, refut...

Math that powers spam filters used to understand how brain learns to move our muscles

...affect the probability of future outcomes, such as taking an alternate route to work on Friday because you’ve experienced heavy traffic Tuesday, Wednesday and Thursday and believe strongly that Friday will be just as bad,” says Shadmehr. E-mail spam filters operate on a similar principle; they predict which...

The insect vector always bites twice

...teran insect. This becomes infected when it feeds, taking blood from an infected vertebrate host. The pathogenic agent finds conditions to reproduce and proliferate in the vector’s body. In most cases, the parasite moves back into the vector’s salivary glands in order to be transmitted to the human host whe...

A new plant-bacterial symbiotic mechanism promising for crop applications

...picales et Méditerranéennes’ and its partners (1), taking as model a symbiosis between a tropical aquatic legume, Aeschynomene, and Bradyrhizobium, bacteria of the Rhizobia family, have just revealed a new mode of communication at molecular level between these two organisms. The bacteria of this original mo...

Study investigates 'divorce' among Galapagos seabirds

...ls around again, a male looks a little ragged from taking care of junior, his mate is likely to choose another. A male’s capacity to raise offspring, a quality that can vary with time, may carry more weight with a mate than stellar genes or past breeding success, Maness said. She used 14 years of data o...

Ancient retrovirus sheds light on modern pandemic

... They reassembled about one-fifth of the virus by taking dozens of PtERV1 sequences and aligning them to create an "ancestral" sequence, teasing out areas of commonality between them. They then used this information to make a partial viral genome. During reconstruction the viral segment was debilitated, en...

Scientists close in on missing carbon sink

... results indicate that intact tropical forests are taking up a large amount of carbon," Stephens explains. "They are helping to offset industrial carbon emissions and the atmospheric impacts of clearing land more than we realized." Capturing vertical movements Most of the computer models produced in...

Antarctic icebergs -- Hotspots of ocean life

At the same time, the wealth of data brought new challenges in how to manage this avalanche of information. “The whole is definitely gr...

Modified mushrooms may yield human drugs

...ls, Dr. Romaine explained. "What we are doing is taking a gene, as for example a drug gene, that is not part of the mushroom, and camouflaging it with regulatory elements from a mushroom gene. We then patch these genetic elements in the plasmid and insert it back into the bacterium," he added. The resea...

He hoped the vaccine would ultimately be able to protect people against both diseases in the one shot and, even better, the recombinant vaccine...

Molecule that destroys bone also protects it, new research shows

"Developing knowledge about the molecules that contribute to host defense versus pathology is very important for gaining a fundamental under...

Survival of the rarest: Fruit flies shed light on the evolution of behavior
