US control strategies may make flu epidemics worse, UCLA study shows

...es two biological characteristics, "memory and how adaptable people can be," Blower said. "These characteristics drive human behavior." Blower and her group used people's attitudes toward the seasonal flu to construct their model. With seasonal flu, protective immunity ?a flu shot ?lasts only one year. Thus...

Scientists: As rainfall changes, tropical plants may acclimate

Tropical plants may be more adaptable than commonly thought to changing rainfall patterns expected to accompany a warming climate, new research shows. A University of Florida scientist and other researchers have found that plants in Hawaii have the ability to acclimate to big changes in...

Ape gestures offer clues to the evolution of human communication

...to a particular emotion and, thereby, serve a more adaptable function. For example, a single gesture may communicate an entirely different message depending upon the social context in which it is used. "A chimpanzee may stretch out an open hand to another as a signal for support, whereas the same gesture t...

A buffet for early human relatives

... able to eat a varied diet and therefore were more adaptable in savanna environments than other primates which had a more restricted diet." Other studies have suggested that the diets of human ancestors and relatives became more varied about 3 million years ago when Africa's climate started getting drier a...

Extreme environment changes fish appearance

...s, Lema said. On one hand, the fish may be more adaptable to changing conditions than thought. But refuge-bred fish might well die if reintroduced directly to Devil's Hole in an attempt to rebuild the population. And if an animal's form is so intimately connected to its environment, is it still the same fis...

Study provides first look at the 'birth' of a retina cell

...ommitted to becoming rod cells, but they are still adaptable and have not yet 'become' that type of cell." In mouse models, it takes five to fourteen days for rod cells to become functional, whereas in humans this time period is four to five weeks during gestation. The Swaroop research team also confirmed th...

New test to detect rare proteins in blood

...s compared to ELISA. "The technology is remarkably adaptable to any protein and can be performed in an automated format," notes Greene. He states that the technology will soon be robotized so as to be able to screen for many rare disease-causing proteins using tiny amounts of blood. "It is even possible that o...

UC San Diego partners with Venter Institute to build marine microbial genomics cyberinfrastructure

... architecture is quite general and will be quickly adaptable to other areas of data-intensive science." Collaboratories are virtual laboratories where scientists can collaborate on research from dispersed locations--interacting with colleagues, accessing instrumentation, sharing data and computational resourc...

Animal models show that anabolic steroids flip the adolescent brain's switch for aggression

...d. He says, "Because the developing brain is more adaptable and pliable, steroids could change the trajectory if administered during development." His lab is releasing other new findings, as yet unpublished, that the serotonin system ?implicated in depression ?may never recover. "If you hit the right a...

Infant transplant patients resist infections that kill adult AIDS patients

...ortant because they show the immune system is more adaptable and resourceful than once thought. Something other than T cells is working to resist viruses in the post-transplant patients. The findings also suggest an intriguing strategy for developing new treatments for AIDS, cancers and diseases of impaired i...

Carnegie Mellon scientists develop tool that uses MRI to visualize gene expression in living animals

... presence of the MRI reporter. "Our technology is adaptable to monitor gene expression in many tissue types. You could link this MRI reporter gene to any other gene of interest, including therapeutic genes for diseases like cancer and arthritis, to detect where and when they are being expressed," Ahrens said....

X-Ray Beams And Fruit Fly 'Flight Simulator' Aid Scientists' View Of Muscle Power

...uman cardiac muscle, mean that the research may be adaptable for other uses. “Both insect flight and human heart muscles store energy during each beat that is later used to help flap the wings or expand the heart after contraction. We found that flying insects store much of the elastic energy in the protein f...
