Ebola virus: from wildlife to dogs

...to the non-human primate and then to humans. It is quite possible that several reservoir species co-existent and that many other animal species can become infected, thus contributing to propagation of the virus in nature. A serological investigation conducted from 1980 to 2000 on 790 nonhuman primates fro...

NASA probe could reveal comet life, scientists claim

...med some 4.6 billion years ago. "This material is quite porous, so it is daring again to predict that subsurface ponds or lakes form transiently due to heat penetrating the exterior crust. We can thus expect biology on comets to have similarities with antarctic biology," added Professor Wickramasinghe. ...

Major new UNC-based drinking water study suggests pregnancy fears may be overstated

...nsive problem to solve. Reducing exposure would be quite expensive for the water utilities and ultimately their customers." The methods used in the new work make it the most ambitious and sophisticated study ever done on this issue, he said. Savitz, Cary C. Boshamer distinguished professor and chair of e...

Ancient DNA helps clarify the origins of two extinct New World horse species

...t horses in each species "varied in size and shape quite a bit" regionally and temporally, Cooper explains, "we see no genetic evidence that these are different species." If true, the study's new model could provide a tool for exploring how environmental adaptations give rise to morphological variation. ...

Map of life on Earth could be used on Mars

... in terms of bacterial evolution that is still not quite clear, " Blank said. "What we're trying to resolve is the evolutionary history of the core of the bacterial cell. The core is that which is not undergoing this lateral gene transfer, or does it extremely rarely." Jumping genes Jumping genes may be ...

Team Invents Device For Weighing Individual Molecules

...method of determining atomic-scale masses would be quite useful in areas such as quantum optics, in which individual atoms are manipulated. The next step for Roukes' team at Caltech is to engineer the interfaces so that individual biological molecules can be weighed. For this, the team will likely collabo...

Fat's fate depends on its source

...rchers restored fat to the animals' diets. "It is quite paradoxical," Semenkovich said. "When we inactivated fatty-acid synthase in the liver and eliminated fat in the diet, the animals became sick, with livers full of fat." Further study found that, in the absence of new fat, the mice exhibited a marked...

Program finds lost genes in nematode genome

... accuracy for a complex genome," Brent said. "It's quite a step up from what you see in the human genome, for instance, where not even a third of the genome can be predicted exactly. The 60 percent is the highest accuracy published for a multicellular organism." C. elegans is a biological model for animal...

UI researcher studies deafness in fruit flies, humans

... experiments are next to impossible in humans, but quite feasible in the fruit fly." "Understanding how this protein works and examining its functional role in hearing will provide new insights into auditory mechanisms, not only in fruit flies, but in humans, as well," he says. ...

Researchers develop promising new gene network analysis method

...e combination of statistics and network theory ?is quite novel. This should be an important new approach to studying gene expression." ...

Diabetic nerve therapy shows 'striking' results

... Life Sciences. "This approach to gene therapy is quite different to previous attempts at treatment as we do not inject a gene that produces a 'foreign' copy of a therapeutic protein. This is the normal approach and has problems from immunological side-effects. "Instead, we turn on the patient's own gene...

To translate touch, the brain can quickly rearrange its sense of the body

...ay from the body, even though the arm was actually quite still. If subjects held their left index finger with their right hand while this happened, they felt their left index finger getting longer as they felt their arm move. The team then tested how these bodily illusions rearranged the sense of touch. T...

Researchers Discover That Microbes Can Produce Miniature Electrical Wires

... width (20,000 times finer than a human hair), but quite durable and more than a thousand times long as they are wide. “Such long, thin conductive structures are unprecedented in biology,?said Lovley. “This completely changes our concept of how microorganisms can handle electrons, and it also seems likely...

Novel plague virulence factor identified

... the interaction between Y. pestis and the worm is quite similar to what occurs in mammals, including humans. The work indicates that the pathogen may use similar virulence mechanisms to infect evolutionary disperse organisms. These findings are important, the researchers continued, since the pathogenesis...

New Look at DNA Hints at Origin of UV Damage

... the interaction between Y. pestis and the worm is quite similar to what occurs in mammals, including humans. The work indicates that the pathogen may use similar virulence mechanisms to infect evolutionary disperse organisms. These findings are important, the researchers continued, since the pathogenesis...

Human embryonic stem cells have the potential to develop into eggs and sperm in the laboratory

...ronment conducive for sperm and egg development in quite a short time in culture." Speaking before the conference, Prof Moore said: "One of the reasons for doing this research is that it may allow us to investigate the very earliest processes of how a human gamete and gonad (ovary and testis) develops. Ma...

New protein vital for immune response is found in surprise location

...oped strategies to evade the host's immunity. It's quite possible that some viruses may target MAVS in order to achieve successful infection. In those cases, therapies that enhance MAVS expression or activity may be a viable option for boosting immune responses against viral diseases." The fact that MAVS ...

Snapin: A protein with therapy potential for autism

...display not only fewer branches, but also show two quite different dendrite patterns. Firestein's most recent work explores the how and why of dendrite branching and patterning. "It's not just how many branches there are, but where they are and the pattern they form," said Firestein, an assistant professo...

Thinking the pain away? Study shows the brain's painkillers may cause 'placebo effect'

...ted feeling less pain. The mind-body connection is quite clear." The findings are based on sophisticated brain scans from 14 young healthy men who agreed to allow researchers to inject their jaw muscles with a concentrated salt water solution to cause pain. The injection was made while they were having th...

Scientists focus on 'dwarf eye'

...ze and shape. "Eyes with nanophthalmos still work quite well, despite these complications," said Sundin. "But the disease's secondary complications later in life, including glaucoma or detached retina, are far more severe and can lead to complete blindness." One such patient with nanophthalmos, an Amish-...
