Some like it hot: Worms at deep-sea vents favor a fiery 45-55°C

...ters to the worms' remote habitat, Girguis and Lee brought the worms to their special aquarium, leaving the deep-sea creatures free to choose any temperature between 20 and 61 degrees Celsius (58 and 142 degrees Fahrenheit). When this thermal gradient was established, all the worms migrated to parts of the t...

Creation of antibiotic in test tube holds promise for better antibiotics

...s. "Our work, while not explaining everything, has brought us much closer to that understanding, in particular the beautiful structure solved by the Nair group," he said. Van der Donk previously had identified the molecular activity of another enzyme (LctM) responsible for naturally turning a small protein ...

Poison dart frog mimics gain when birds learn to stay away

...njoy the protection of the predator generalization brought on by more toxic species in the community." Taking predator avoidance learning into account, says Cummings, you can successfully predict a specific direction of mimicry in evolution. In studying the toxicity and abundance of all three species, Dars...

Genetically engineered mosquitoes show resistance to dengue fever virus

...ngue infection, but this is the first time we have brought all the pieces together to create a stable model that can also reproduce." In the study, the researchers exploited a vulnerability of the dengue virus to make the mosquitoes resistant to infection. This vulnerability occurs when the virus replicates...

World Trade Center identifications pushed forensic DNA technology

... of the victims and worked with them. The contact brought perspective to the project, friendships and, at times, emotional turmoil. "Working with the families is critical to getting the job done properly, and the truth is that the medical examiner and the police need to establish a synergistic relationship...

ASU researchers find link between social behavior, maternal traits in bees

... flight. Amdam and her team recorded what the bees brought back from the forage and measured their ovaries. Results from the experiment validated her hypothesis, showing that pollen collection was primarily conducted by worker bees with larger ovaries, cementing the connection between high pollen-hoarding ...

Illegal trade is propelling rare turtle toward extinction, new report

...ot been illegally taken from the wild or illegally brought into the United States," said Simon Habel, Director of TRAFFIC North America. "Roti Island snake-necked turtles should not be purchased unless they have proper permits and documentation. Without strict enforcement of these laws the turtle will have...

New fruit fly protein illuminates circadian response to light

A mutant fruit fly that possesses jetlag-like behaviors enabled senior author Amita Sehgal, PhD, Professor of Neuroscience at Penn and a Howard Hughes Medical Institute (HHMI) Investigator, and col...

Honey helps problem wounds

...fused to heal for years can, in our experience, be brought under control with medihoney ?and this frequently happens within a few weeks,' Kai Sofka says. In the meantime two dozen hospitals in Germany are using honey in their treatment of wounds. Despite all the success there have hitherto been very few rel...

UF scientists discover evolutionary origin of fins, limbs

...ink the genetic tools for fin development would be brought together in that place," said developmental biologist Martin Cohn, Ph.D., an associate professor with the UF departments of zoology and anatomy and cell biology and a member of the UF Genetics Institute. "We've discovered that the genetic circuitry f...

Mitochondrial DNA sequencing tool updated

...essed slowly or stalled. By 1996, new technology brought new opportunity. Scientists with the company Affymetrix in Santa Clara, Calif. developed the first mitochondrial sequencing microarray. Roughly the size of a quarter, the silicon chip had lithographically annealed to it up to 135,000 short, arrayed...

Super-sized cassava plants may help fight hunger in Africa

...variety of cassava native to Colombia (cassava was brought to Africa from South America by the Portuguese in the 1500s.) They inserted into three cassava plants an E. coli gene that controls starch production. A non-modified fourth plant served as a control. "Cassava actually has this same gene," Sayre said...

Viagra improves high altitude exercise performance up to 45% for some

... more than others," Friedlander said. "With it, it brought them back up to the levels of the non-responders." The results suggest that the responders experienced a greater degree of constriction of the vessels in the lungs at altitude and therefore benefited more from the vessel relaxation effects of sildena...

Drug discovery team to explore newly discovered deep-sea reefs

...ni because pieces of reef-building corals had been brought up using surface-operated dredge and grab sampling equipment. However, just as the vast majority of the ocean remains poorly mapped and unexplored--even off Miami--these potentially important areas remained unseen. In December of 2005, as part of th...

A control group of five rats underwent the same procedure. Instead of the chondroitinase, they were given a saline solution. None showed any nerve growth out o...

Successful transplantation from pig embryos to mice

...the Weizmann Institute's Immunology Department has brought the possibility of transplants from pig embryos one step closer. The results of the study appeared in the June issue of PLoS Medicine. In previous work, Reisner and his team had shown that each embryonic organ has its own 'time window' during which...

UN review shows need to halt destructive fishing practice

... with a partnership of leading environmental NGOs, brought scientists together at the Defying Ocean's End Conference in Los Cabos, Mexico, to develop an agenda for maintaining healthy oceans. The conference recommended a U.N. moratorium on high seas bottom trawling and helped spawn the Deep Sea Conservation ...

Flick of whiskers helps tease out brain's 'shadow' signaling system

...er team has made a series of discoveries that have brought the once-obscure astrocyte and its signaling capability into prominence. In the latest work, graduate student Xiaohai Wang, M.D., led a team that focused the laser system on the brain cells of mice as their whiskers were gently pushed about with gen...
