Tarantula venom and chili peppers target same pain sensor

...ic activators or blockers on these channels can be designed to treat persistent pain ?from arthritis, bladder infections, or other diseases." The researchers determined the venom peptides' effect in neuron cell cultures, measuring the tell-tale rush of calcium ions when the venom peptides contacted the TRPV...

Global changes alter the timing of plant growth, scientists say

...dge Global Change Experiment, launched in 1998 and designed to demonstrate how a typical California grassland ...sper Ridge Biological Preserve. The experiment was designed to simulate environmental conditions within the range that climate experts predict may exist 100 yea...

The subtleties of tropical forest demise

...ating and alleviating the emerging threats. "We designed this book for a very broad audience," said Laurance. "It's for anyone interested in the fate and survival of tropical ecosystems. "The book includes syntheses by many world-leading authorities as well as original, data-rich studies. About the Edi...

To slow AIDS in Russia, treat HIV-positive addicts, Stanford study says

...Owens called the approach a "thought experiment," designed to predict how treating different groups in the population would affect the overall epidemic. "Exclusively treating non-drug users is not a wise approach. It's the least efficient and it's the least effective," said Long. According to the model...

Clue found to Epstein-Barr virus' ability to form and sustain tumors

...tional Research Center for Environment and Health, designed genetic experiments to mutate various segments of the 640 amino acids that make up the EBNA-1 protein, which is one of about 100 proteins EBV encodes. They then infected human B cells with EBVs carrying various mutant EBNA-1s. The analysis showed t...

Hopkins scientists link immune response to 'ghost' parasites and severely congested sinuses

...men participated in the two-year study at Hopkins, designed to find out if any of the genetic traits already known to be common in asthmatics were as active in patients with sinusitis. Twenty-two were scheduled to have surgery for sinusitis, while the remaining 11 served as study controls, having surgery for...

Mysterious 'neural noise' actually primes brain for peak performance

... relatively undemanding. The brain is apparently designed in a similar manner--"coding" the possibilities it encounters into a format that makes it tremendously easier to compute an answer. Pouget now prefers to call the noise "variability." Our neurons are responding to the light, sounds, and other sens...

Malaria may fuel spread of HIV in sub-Saharan Africa

...al Research Division. Using a mathematical model designed by Abu-Raddad that was based on HIV and malaria co-infection data in Malawi measured and collected by Kublin, the scientists for the first time were able to assess quantitatively the impact of malaria on HIV and vice versa, as well as provide the fir...

Ebola-outbreak kills 5000 gorillas

... impact on large, remote protected areas that were designed to be the bulwarks of ape conservation efforts. Ebola has not totally made apes totally extinct from these areas but it has pushed once huge populations down to smaller sizes at which they are dramatically less resilient to illegal hunting and other ...

Detailed 3-D image catches a key regulator of neural stem cell differentiation in action

...ady started that structure-based program. "We have designed the first generation of inhibitors and now it is a matter of chemically synthesizing them, testing them in test tubes and cells, and imaging them bound to Scp1 in 3D," says Noel. This will set the stage for the rational fine-tuning of their efficacy ...

New sunscreen ingredient to heal sunburn and help prevent skin cancer

...es. After three years of research, the team has designed two commercially attractive prototypes which are currently in laboratory trials. The prototypes contain 'caged' iron binding sites which release the chelators only in response to high doses of UV light, thus avoiding toxicity to cells. The new s...

First Biodiversity Census of coral reef ecosystems in the NW Hawaiian Islands

...cosystems (CReefs) project. The CoML projects are designed to assess the diversity, distribution and abundance of ocean life and explain how it changes over time. This CReefs project will provide needed baseline information and foster understanding of coral reef ecosystems globally. The cruise will take pla...

Lab-on-a-chip could speed up treatment of drug-resistant pneumonia

...celr8 technology is a "microfluidic" lab-on-a-chip designed to manipulate and analyze bacteria without growing...nisms are then separated, suspended in a specially designed fluid, and pumped into the chip. Inside the chip, the bacteria flow into several different compar...

Giant insects might reign if only there was more oxygen in the air

...ae grow disproportionately This experiment was designed to find out: how much room the tracheal system takes up in the bodies of different-sized beetles whether tracheal dimensions increase proportionately as the beetles get larger whether there is a limit to the size a beetle could grow in th...

'Trojan Horse' agent halts bone metastasis in mice

U-M researchers use nanoparticles to target brain cancer

...ze can be loaded with high concentrations of drugs designed to kill brain cancer. What's more, these nanoparticles can be used to image and track tumors as well as destroy them, according to researchers at the University of Michigan Comprehensive Cancer Center. Researchers incorporated a drug called Photofri...

Engineer ramps up protein production, develops versatile viral spheres

...vaccine maker could attach a very specific protein designed to stimulate only the appropriate immune-system cells. A vaccine with these well-targeted capsids would be more likely than a traditional vaccine to elicit a strong and specific response. The capsid method is akin to advertising a product directly to...

Squid-inspired design could mean better handling of underwater vehicles
