UGA study explains peaks and troughs of dengue epidemics

...in mosquito-infested areas. And the ease of travel brings the virus to areas that were previously dengue-free when a mosquito bites an infected traveler and then spreads it to others. According to the Centers for Disease Control and Prevention, Aedes aegypti and the related Aedes albopictus (the Asian tiger...

Genetically altered mice no longer like cocaine

... genetic modifications be made in humans, the work brings to light the key protein that controls cocaine's effects in the body, which may help scientists develop medications that achieve the same results and therefore help addicts overcome their dependence. Right now there are no such treatments on the mar...

Nanopore method could revolutionize genome sequencing

... DNA as it passes through tiny pores. The advance brings personalized, genome-based medicine closer to reality. The paper, published in the April issue of the journal Nano Letters, describes a method to sequence a human genome in a matter of hours at a potentially low cost, by measuring the electrical per...

Inside rocks, implications for finding life on Mars

...en done before. If a future space mission to Mars brings rocks back to Earth, Schopf said the techniques he has used, called confocal laser scanning microscopy and Raman spectroscopy, could enable scientists to look at microscopic fossils inside the rocks to search for signs of life, such as organic cell w...

A large step forward in the fight against African sleeping sickness

...ct that binds immediately to the parasite and thus brings the ApoL-1 variant to the place where it can carry out its neutralizing action. All the tests performed on mice have been very promising: Trypanosome-infected mice survive after 1 treatment. The parasite is removed from the blood and all effects as...

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

...or much of the CAMERA genomic data. The project brings together new technologies of high-throughput DNA sequencing and metagenomic analysis tools on the one hand, and cyberinfrastructure innovations on the other. Together, they will provide new tools to help marine microbial ecologists access and derive ...

Cheaper and simpler keyhole surgery

Endoscopic surgery brings many advantages for patients but is very difficult for the surgeon. Working at the Academic Medical Centre in Amsterdam, Joris Jaspers has developed two instruments which make this approach easier and also cheaper than with existing surgical robotics...

Potential vaccine developed for deadly leishmaniasis disease

...isease," Seeberger stated. "This candidate vaccine brings something new to the table and may be of use not only in humans but also for pet vaccines. Dogs get leishmaniasis, particularly in Southern Europe and a vaccine is urgently needed there, as well." Carbohydrate vaccines already are used in everyday m...

Waking a sleeping virus

...olecule is a protein called ZEBRA, which the virus brings along as it infects human cells. ZEBRA is essential to switching the virus from its latent to its active state. "During an infection, EBV inserts its own DNA into the nucleus of human cells. This information contains the codes for about 100 genes," s...

Pittsburgh researchers discover that certain chemicals in the blood may indicate brain injury

...rtant for physicians to realize that the adult who brings a child to the Emergency Department may have no idea that the child is being abused by another family member, babysitter, family friend or nanny." ...

Study finds drug may cut down involuntary movements

... are killed off by a mutant protein. The disease brings with it an array of other difficulties as well, including cognitive problems, changes in personality, and psychiatric problems like depression. As many as one-quarter of patients with the disease attempt suicide, and many suffer from progressive cogn...

High-tech tags on marine animals yield valuable data for biologists and oceanographers

...h Costa on the sea lion studies. "This technology brings a whole new dimension to our understanding of how ...mperatures. Normally, upwelling of cold deep water brings nutrients into the coastal waters off California and supports a highly productive food web. But the ...

Infections could contribute to adult brain tumours

...e cause of brain tumours and we think our research brings us closer to understanding more about this disease. "We only found clustering of cases in the East of the province we investigated, and we think it could be something to do with the way infections spread in less densely populated areas." However,...

Natural selection at single gene demonstrated

...nt studies based on intrinsic genomic comparisons, brings biology closer to this goal. ...

New Rotavirus vaccine joins routine infant immunization schedule

...sents a significant milestone in public health. It brings us a step closer to our ultimate goal of eliminating childhood disease." Nearly every child experiences infection with rotavirus, usually as gastroenteritis. In the United States, children under age five experience an estimated 2.7 million episodes...

Underdogs in the understory: Study suggests nature favors rarer trees

...es from the same kinds of underlying processes. It brings us a step closer to understanding the causes of the world's amazing biodiversity," Tilman said. Muller-Landau contributed quantitative skills for analyzing and interpreting the data. "After all the effort that went into the analyses, it was neat t...

Simple idea to dramatically improve dengue vaccinations

...en the immune system identifies infected cells and brings pieces of them into the lymph node for targeting. Within a few days of infection, the immune system completes a massive scan of the 100 million available T-cells in its arsenal. Through a complex trial-and-error process, it identifies three to five T...

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

...stroke and some types of cancer. Withdrawal often brings depression, and recent research suggests that some AASs may even be habit-forming. Overseen by Richard Melloni Jr., PhD, of Northeastern University in Boston, the current study of 76 adolescent hamsters compared how individual hamsters behaved when...

Do the Europeans turn ill sitting up so late?

...cquire the funding. This sleep restriction project brings together researchers from five countries, thus creating an efficient network where the special skills of each partner can be utilized. The network will provide funding for 24 doctoral and post-doctoral researchers.A high level research training prog...

First big influenza genome study reveals flu evolution

...eople worldwide. In the U.S., a typical flu season brings 36,000 deaths and 114,000 hospitalizations. Over the past century, three pandemics--in 1918, 1957, and 1968--caused millions of deaths. Today, scientists worry that virulent influenza strains in other species, such as the H5N1 bird flu strain found ...
