Prehistoric mystery organism verified as giant fungus

...Dawson interpreted them and other information that helped understand this humongous fungus," she said. Hueber also traveled to Canada, Australia and Saudi Arabia to collect specimens. He tediously sliced them into hundreds of thin sections and made thousands of images taken through microscopes to determi...

Flavanols in cocoa may offer benefits to the brain

...chief science officer at Mars, Incorporated, which helped sponsor today’s symposium and has supported research on cocoa flavanols for more than 15 years. “The findings raise the possibility that products utilizing this cocoa could be developed to help maintain healthy brain function throughout several life...

Birth rate, competition are major players in hominid extinctions

...small animals and forage." Cultural adaptations helped these opportunists to take advantage of whatever food was available. But culture did not seem to help the Neandertal. Tremendously successful from about 200 to 50 thousand years ago, they suffered a gradual decrease and extinction from about 30 to ...

Strawberry daiquiris -- the extra-healthy cocktail?

...ging activity within the fruit. While such a boost helped the berries resist decay, the same compounds would also be expected to make the strawberries healthier to eat. Dr Korakot Chanjirakul and colleagues at Kasetsart University in Thailand, in collaboration with scientists at the United States Departm...

Researchers urge monitoring of bone health during chemotherapy

...side effects of chemotherapy induced bone loss and helped tumors grow in bone. So the researchers at Washington University School of Medicine in St. Louis are recommending increased awareness of bone health during cancer treatments. The medication studied is a growth factor commonly used to help cancer pa...

New study may show how to forestall a fatal, virus-caused immune-system meltdown

... all the strands to move, and the Ingenuity system helped us see and comprehend connections we would have missed otherwise.? Connecting those strands is critical to diagnosing and restoring balance to an immune system gone haywire in a disease like Lassa fever. “Early on, you can’t really differentiate th...

Researchers from the UGR use a bacterium to obtain biopreservatives from food

...stability and biological activity, and it has also helped us understand how this molecule permeabilizes bacterial membranes." Competition for nutrients Over the course of evolution, microorganisms have developed several strategies to compete for nutrients in their environment. One of these strategie...

Scientists find potential 'off-switch' for HIV virus

...nal Public Library of Science Biology. "We have helped understand how HIV can turn off, and in doing so I believe we've uncovered an important component of the biological switch," said Weinberger, a Lewis-Thomas Fellow in Princeton's Department of Molecular Biology. "If we can figure out how such resisto...

Phthalates now linked to fat, related health risks

...his connection between phthalates and testosterone helped to establish a basis for the study, Stahlhut said. Stahlhut’s group hypothesized that phthalates might have a direct link to obesity, since low testosterone appears to cause increased belly fat and pre-diabetes in men. They analyzed urine, blood s...

Surgeons develop simpler way to cure atrial fibrillation

...says. "So we started working on new technology and helped develop an effective ablation device that simplifies the procedure. Not only is Cox-maze IV shorter, but with the new device the procedure is also much safer because there's a much lower risk of bleeding." Atrial fibrillation affects more than 2.2...

First-degree fetal heart block may be reversible

...cs, Gynecology & Reproductive Sciences at Yale helped conduct the PR Interval and Dexamethasone Evaluation (PRIDE) study with a team of other researchers to evaluate an early marker of cardiac injury before there is permanent scarring. The PRIDE group conducted a longitudinal (observational) study fo...

New mechanism for nutrient uptake discovered

...nitrogen uptake in plants. That identification has helped other researchers find the relatives of these genes in a variety of species from bacteria to humans. In this study, the scientists wanted to identify how ammonium transport is regulated. Plants import nitrogen in the form of ammonium from the soil...

Robotic therapy helps restore hand use after stroke

...15 sessions. For seven patients, HOWARD shaped and helped complete movements across all sessions, while six had complete support from HOWARD for only the second half of the sessions. At the end of three weeks, all patients had improved in their ability to grasp and release objects. Their average score on...

McBride shows DNA detective work with paper-eating bacteria that 'glide'

..., straw and grain hulls. A UWM professor recently helped DOE do just that by analyzing the DNA of a bacterium that can break down cellulose, the major structural component of plants that is also found in forestry by-products (including paper) and waste feedstocks. Mark McBride, a professor of biological ...

Female Antarctic seals give cold shoulder to local males

...tic diversity of fur seal populations and may have helped them recover so successfully from near extinction only 100 years ago. This could in turn affect how well they respond to future challenges such as climate change." Antarctic fur seals were nearly hunted to extinction in the 17th and 18th Centuries...

Enhancing activity of marijuana-like chemicals in brain helps treat

...to the active compounds in marijuana and hashish, helped trigger a dramatic improvement in mice with a condition similar to Parkinson's. "This study points to a potentially new kind of therapy for Parkinson's disease," said senior author Robert Malenka, MD, PhD, the Nancy Friend Pritzker Professor in P...

Scripps research study shows humans and plants share common regulatory pathway

...tudy also showed that a heat shock protein, HSP90, helped stabilize Nod1. "Inhibiting HSP90 resulted in a significant reduction of Nod1 protein levels," Ulevitch said. "That clearly suggests that this protein plays a key role in stabilizing Nod1 and protecting it from degradation. In contrast, turning o...

Super-fermenting fungus genome sequenced

...tion embedded in the genome sequence of Pichia has helped us identify several gene targets to improve xylose metabolism,?said Pichia paper lead author Thomas W. Jeffries of the Forest Products Laboratory in Madison, Wisconsin. “We are now engineering these genes to increase ethanol production.?Jeffries sai...
