A frog's life is food for thought

...ea of the gut of aestivating frogs, they appear to actually increase their absorptive capacity during aestivation," she said. "Within 36 hours of the ingestion of the first meal the gut had all but returned to its pre-aestivation state, and by the completion of digestion of the first meal the gut was operati...

Transgenic plants remove more selenium from polluted soil than wild plants, new tests show

...many areas where selenium is deficient, so farmers actually pay for animal feed that is supplemented with selenium," said Terry. "Farmers would love to have this source of selenium." Other co-authors of the study include Danika L. LeDuc, a post-doctoral researcher at UC Berkeley's Department of Plant and Mic...

New Drugs For Bad Bugs: UF Approach Could Bolster Antibiotic Arsenal

...a small needle probe to measure how much of a drug actually ends up in the fluid surrounding the bacteria at sites of infection and are among the first in the country to test the method in people. These concentrations can differ widely from those found in the bloodstream, said Derendorf, who has published res...

Scientists discover how plants disarm the toxic effects of excessive sunlight

...elds of study. For example, too much sunlight can actually be harmful to plants, because the heightened photosynthetic activity also means an increase in singlet oxygen. By modifying plants to enhance the protective pathway, "we could be able to get larger crop yield per photon of light," he says. And by ma...

Love's all in the brain: fMRI study shows strong, lateralized reward, not sex, drive

...our confidence that self-report questionnaires can actually measure brain activity." Aron also noted that the research answered the "historic question of whether love and sex are the same, or different, or whether romantic passion is just warmed over sexual arousal." He said, "Our findings show that the brai...

Harmful chemicals may reprogram gene response to estrogen

...g critical developmental periods early in life may actually "reprogram" the way certain genes respond to the f...people with a genetic predisposition for a disease actually develop the disease. The new research shows that when rats with a genetic predisposition to uterine...

Nano-bumps could help repair clogged blood vessels

...h firmly it can become loose, and parts of it will actually break off and go down the bloodstream," Webster said. "Essentially, what we've been trying to do is find new materials that cause the endothelial cells to attach better to these stents without creating as much dangerous scar tissue." The researchers...

Test for early detection of prostate cancer shows promise

...biopsies because they have elevated PSA values are actually positive for prostate cancer, while as many as 15 percent of those with low PSA values were found to have prostate cancer as detected by biopsy, according to Getzenberg. Larger clinical trials are under way to further refine the EPCA test, to make i...

Study reveals new technique for fingerprinting environmental samples

...in, who led the research team. "With EGTs we don't actually need a complete genome's worth of data to understand the functions required of the organisms living in a particular setting. Rather, the genes present and their abundances in the EGT data reflect the demands of the setting and, accordingly, can tell ...

Different microarray systems more alike than previously thought

...ds of information generated by these systems might actually be comparable, even though many different systems are used by many different laboratories. "Biologists occasionally ask me what is the best platform on which to run microarray experiments, but there hasn't been a good answer to that question," said ...

Scientists journey to southern Africa to unravel the secret world of elephant communication

...s, and to the scientific community, that elephants actually have the physical capability to send and receive low-frequency vibrations. To do that, they had to convince skeptical geophysicists, like Hart's brother, Byron Aranson. "It was a unique collaboration," Hart says. "We started with the physics of it, ...

Researchers discover underwater volcano

...w stands at 300 meters, or nearly 1,000 feet. "To actually have a documented case of an underwater volcano that has emerged within an accurate period of time is very rare--this is one of those cases," said Staudigel. Scientists were tipped off to the volcano's existence when they profiled the seafloor of th...

At long last, scientists figure out how plants grow

...ains unclear whether the pairing of ABP1 and auxin actually stimulates plant growth. The research reported by Estelle, Dharmasiri and Dharmasiri was funded by grants from the National Science Foundation, the National Institutes of Health and the U.S. Department of Energy. To speak with Estelle, please call ...

Roots Engage in Underground Chemical Warfare

...fers one explanation for why so few bacteria types actually cause disease in plants. Of the more than 50,000 plant diseases occurring in the United States, fungal pathogens are the leading cause. "Current understanding of plant defenses does not readily explain why a pathogen can cause disease in one plant s...

Africa to take it on chin again with climate change

... of those runs showed the magnitude of drying that actually occurred in southern Africa. When the models did include the Indian Ocean warming, southern Africa consistently dried out. The models also project that by 2049, monsoons across southern Africa could be 10% to 20% drier than the 1950-99 average. A di...

Oceans more vulnerable to agricultural runoff than previously thought, study finds

...e gulf and lasting several days. "Sometimes eddies actually pulled the plumes across the gulf, from the mainland side all the way to the Baja Peninsula," Beman added. "Mike found that immediately following each one-week window in which much of the valley was irrigated, there was a response in the ocean off t...

Doctors closer to using gene analysis to help trauma patients

...ents who experience severe trauma or burn injuries actually do well,?said Lyle Moldawer, a surgery professor in UF’s College of Medicine. “They’re resuscitated at the scene, taken to the hospital, have an uneventful recovery and they’re discharged. But there’s a certain fraction who go on to develop complicat...

Protein prevents detrimental immune effects of bacterial sepsis

...esponse meant to clear the pathogen and its toxins actually causes damage to the host's own tissues when it goes into overdrive, releasing too many immune signals. Thus, the immune response must be carefully controlled to prevent damage to the host. Damazo et al. studied this balancing act by analyzing the e...

The lopsided brain: Attention bias is shared by humans and birds

... to play a requisite role in pseudoneglect may not actually be essential for this phenomenon, but also that pseudoneglect may reflect evolutionary adaptations that allow animals to devote attention to multiple aspects of their environment. The findings are reported in the May 24 issue of Current Biology by B...
