Earth Rx: A microbial biotechnology prescription for global environmental health

... of microorganisms." Rittmann is motivated by the huge benefits that environmental biotechnology and microbial communities can bring to society. "I think if we could succeed in capturing the energy out of waste materials, this would be a world-transforming technology and a real step forward to using mor...

Rhinos clinging to survival in the heart of Borneo, despite poaching

...nd the forests of the "Heart of Borneo" still hold huge tracts of continuous natural forests, which are some of the most biologically diverse habitats on Earth, with high numbers of unique animal and plant species. This is one of the world's only two places ?the other being Indonesia's Sumatra island ?whe...

World shark attacks dipped in 2005, part of long-term trend

...er, he said. "We need to remember there have been huge changes in how humans use the water over the last 20 to 30 years," Burgess said. "When our parents and grandparents went into the water, they maybe wiggled their toes, or if they were very daring, jumped in and swam. People of our generation are surf...

Genomics-based vaccine could prevent deadly cattle disease

...dy author and molecular biologist at TIGR. "It's a huge jump forward." To make the jump, researchers used the genome sequence of the parasite responsible for East Coast fever. A tick-borne parasite, Theileria parva , causes the disease. When ticks infected with T. parva bite cattle, they transmit the ...

How the octopus forms an elbow

...matched by the human arm. Nonetheless, despite the huge evolutionary gap and morphological differences between the octopus and vertebrates, the octopus arm acts much like a three-jointed vertebrate limb when the octopus performs precise point-to-point movements. Researchers have now illuminated how octopu...

Key heart and Alzheimer's disease protein imaged for first time in native state

...Libeu, a GICD and GIND research scientist. "It's a huge step forward for those of us involved in the field." ApoE, and particularly apoE4, has long been studied for its role as a lipid transport protein and its involvement in cardiovascular disease. Much of the pioneering work on this molecule has been d...

Molecular mechanism may explain how fevers spark seizures

...her incidence of developing epilepsy. "There's a huge incidence of febrile seizures, so even though only a small percentage -- 2 to 4 percent -- progress to epilepsy, it represents a large burden of epilepsy in the world," Macdonald said. "Our findings are attracting attention because they show a novel ...

New antimicrobial compound adheres to skin to promote healing

...ally, getting staph infections from scratches is a huge problem. Our bioadhesive can adhere to wet skin, cleanse the wound and promote healing," he said, adding that they're also looking at a non-oily gel formulation for use as a combination cleanser and ointment for killing acne-causing bacteria. ...

UMaine teams with fishermen to study affects of trawling on seafloor ecology

...r a significant amount of time. We're not seeing a huge trajectory change, but we can say it is recovering toward stability." ...

Scientists force viruses to evolve as better delivery vehicles for gene therapy

... delivery vector for genes. "We think there are a huge variety of new problems we could address as well, such as targeting the virus to cells it is ordinarily not good at getting into, or speeding its transport through the body," he said. Though Schaffer acknowledges that the technique could be used to ...

Scientists identify molecular structure of key viral protein

...isease, which kills chickens. Measles still causes huge numbers of deaths worldwide. And while HIV, influenza and SARS are not in the same family, the viruses do share a mechanism similar to that used by paramyxoviruses for entering the host cell." The parainfluenza virus 5 is also closely related to two...

Scientists discover new genetic subtypes of common blood cancer

...tial genes and proteins within the subgroups "is a huge advance," comments DePinho. "If you know that a certain gene is driving the disease and influences the clinical behavior of the disease in humans, it immediately goes to the top of the list as a prime candidate for drug development." ...

Stem cell transplants improve recovery in animal models for stroke, cerebral palsy

...lts in ths U.S. is stroke," said Dr. Hess. "It's a huge public health problem in the world." He hopes one day stem cell therapy, along with aggressive physical therapy and possibly tPA can work synergistically to reduce that disability. "These are not going to be cures, but this level of recovery is sign...

Taipan venom no snake oil

... of killing." Dr St Pierre said snake venom was a huge untapped source of potential drug therapies. His study is the most detailed ever conducted on the genes responsible for Australian snakes' toxins. It is hoped a comprehensive study of all the venom components from Australian snakes may yield further...

Genes affecting blood pressure change as children become adults

...y influencing blood pressure and hemodynamics. The huge twin cohort and some complex mathematical modeling made it possible to quantify the role of genetics. They found genetics played a moderate to high role, explaining between 25 and 64 percent of the individual differences in blood pressure and hemod...

Albatross study shows regional differences in ocean contamination

...ar to be feeding at the same trophic level. We saw huge differences in contaminant levels, which we attribute, at least in part, to the differences in foraging patterns between the two species," Finkelstein said. The high contaminant load in black-footed albatrosses foraging in the California Current pro...

Biodiversity key to sustainable biofuel according to University of Minn. researcher's findings

... a single prairie species," Tilman says. "That's a huge advantage. Biomass from diverse prairies can be used to make biofuels without the need for annual tilling, fertilizers and pesticides, which require energy and pollute the environment. High diversity allows us to produce biofuels with low inputs, and...

APS lecturer shows rare video of 'teacher-student' immune cell interactions in live animal

...phatic system to the lymph node and proliferate to huge numbers. One of the puzzles von Andrian has been working on, is how foreign invaders manage to proliferate in the very area, the lymph node, where the immune system is marshaling its troops. "So understanding how these (foreign) cells survive in the...

Iron critical to ocean productivity, carbon uptake

..., the sub-arctic north Pacific below Alaska, and a huge area in the tropical Pacific centered on the equator. With their newfound knowledge of fluorescence, the scientists believe they now can use satellite imagery to identify specific areas that are iron-stressed ?and how they respond to changes such as ...
