Wild tigers need cat food

...ortality, yet their numbers remain stable due to a combination of high reproductive rates and abundant prey. The study, which appears in the journal Ecology, underscores the need of maintaining protected areas with high prey densities in an overall tiger conservation strategy, along with anti-poaching efforts a...

Protein folding: Building a strong foundation

...nds meshed together. "In folding study the right combination of expertise in computational and experimental approaches is vital for success," Ma said. "Our collaborative team has set an excellent example for future study." ...

High HPV concentrations combined with smoking significantly raise risks of cervical cancer

Twenty Years of Malaria Research: Outcomes and Perspectives

... has carried out crucial research into artemisinin combination therapies (ACTs) aimed at combating the rapid rise in drug-resistance. The unit has carried out the largest number of drug trials in malaria and research at the unit has been influential in changing WHO guidelines for malaria drug treatment. The r...

Biofuel cells without the bio cells

...charge-transfer from protein to mineral, through a combination of techniques that included FCS, or fluorescent correlation spectroscopy, and confocal microscopy. These yielded a "fluorescence intensity trace" whose brightness depended entirely on whether hematite was available to bind with OmcA in solution. No h...

New dwarf buffalo discovered by chance in the Philippines

...he entire buffalo genus. Its discovery on Cebu--in combination with the occurrence of the rare tamaraw on Mindoro and a report of fossil teeth potentially referable to Bubalus on Luzon--indicates that this genus might have once lived throughout the Philippines, most of which is an oceanic archipelago, never conn...

How ants find their way

...later trips to the food site will navigate using a combination of landmarks and memories of the whole landscape. The scientists found the ants even used different sets of landmark memories depending on whether they were on their way to food, or whether they were full and heading back to the nest. Ants store many...

Gene therapy research switches off joint inflammation; switches on genetic process of joint repair

...duct of any kind has been able to demonstrate this combination of actions. These findings have been published in peer-review journals and presented to learned societies. The commercialization of Reparagen has been supported by the US government with a grant from the National Institutes of Health. "Glucosamin...

New data from NIH lab confirms protocol to reverse type 1 diabetes in mice

...omal fluorescence in situ hybridization (FISH), in combination with insulin staining, to follow the fate of male spleen cells transplanted into female recipients. The female mice that received male donor cells consistently showed Y-chromosome-positive insulin-producing islet cells, indicating that the introduced...

Study offers innovative profile of enzyme that aids tumor growth

"Using a combination of enzyme activity and metabolite profiling, we determined that this protein-whose function was previously unknown-serves as a key regulator of a lipid signaling network that contributes to cancer," said Benjamin F. Cravatt, a Scripps Research profes...

Computer-based 'games' enhance mental function in patients with Alzheimer's

...e interactive multimedia internet-based system, in combination with the standard pharmacological treatment of Alzheimer's disease, provides for better cognitive function in these patients, demonstrating that they are capable of benefiting from cognitive stimulation, even after the disease has advanced," said Mr....

New biologic treatment for tennis elbow may replace surgery for chronic sufferers

...ed a course of physical therapy and had tried some combination of anti-inflammatory medicines, bracing or cortisone shots, all without relief of symptoms. Twenty of the original 140 patients evaluated met these strict criteria and were enrolled in the study. These 20 represented the most severe tendonitis pati...

Fat stem cells being studied as option for breast reconstruction

...jected under the skin in a rat model, the cellular combination eventually formed what they describe as a "mound" of tissue. The fat-derived stem cells being used in the study are obtained from breast cancer patients. "We need to demonstrate that fat-derived stem cells taken from a breast cancer patient be...

Scientists identify 36 genes, 100 neuropeptides in honey bee brains

...nes they are encoded by," Sweedler said. Using a combination of the newly available honey bee genome sequence, as well as bioinformatics and mass spectrometry, Sweedler and collaborators from the United States and Belgium inferred the sequences of more than 200 possible neuropeptides and confirmed the sequence...

Eat less, weigh more? Enzyme makes lean mice 'susceptible' to dietary fat

...ces, says Wolfgang, body weight is maintained by a combination of food intake and energy expenditure, how hungry the body is, and how much energy cells need. Many cells in the body use a sugar called glucose as a source of energy. When the body is starved, the body literally feeds on itself, breaking down fat ...

Tastes great! Study shows brain's response to pleasing -- and changing -- tastes

...rs put the rats into a salt-deprived state using a combination of diet and hormones that cause the body to get rid of salt, the picture changed. Suddenly, the rats' brain activity rose as high when they received the salt water as it had when they received sugar water. The effect lasted for a while after the rats...
