Malaria vaccine prompts victims' immune system to eliminate parasite from mosquitoes

...digestive tracts revealed that the antibodies were capable of completely eliminating the ookinettes. The study authors noted that Psv25H, a molecule similar to Pfs25, is found on the surface of ookinettes of another species of Plasmodium that causes malaria, Plasmodium vivax. They wrote that the conjugate...

Sunflower speciation highlights roles for transposable elements in evolution

...ze, are related to infectious retroviruses and are capable of multiplying and inserting themselves at different points throughout a host genome. They are found in virtually all eukaryotic genomes. The new findings not only add an interesting twist to the origin of new sunflower species through hybridizat...

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

...ion in these patients, demonstrating that they are capable of benefiting from cognitive stimulation, even after the disease has advanced," said Mr. Lluís Tárraga, lead investigator of the study and developer of the IMIS tool. "This study shows that tasks aimed at increasing or maintaining mental function ...

A reason why video games are hard to give up

... segment of the computer gaming industry. MMOs are capable of supporting hundreds of thousands of players simultaneously. For those playing MMOs, the need for relatedness emerged "as an important satisfaction that promotes a sense of presence, game enjoyment, and an intention for future play," the researcher...

UGA scientists unravel 'molecular inch-worm' structure of walking-pneumonia bacterium

...heir genome is among the smallest known for a cell capable of a free-living existence." Other researchers, using electron microscopy, have described the basic structure of the terminal organelle, but Krause's team went further, using fluorescence microscopy and fluorescent protein fusions that allowed them...

How many genes does it take to learn? Lessons from sea slugs

... hundred billion neurons in humans - the animal is capable of learning and its brain cells communicate in many ways identical to human neural communication. In the new findings, scientists identified more than 175,000 gene tags useful for understanding brain functions, increasing by more than 100 times th...

USC team reveals structure of APOBEC family protein

...hundreds of billions of different antibodies, each capable of targeting a specific disease-causing agent. Others have been shown to disarm viruses like HIV and hepatitis B. Uncontrolled, of course, the APOBEC proteins could create havoc in a cell. But normally, under the cell's tight regulation, "these ar...

Scientists resuscitate a 5 million-year-old retrovirus

...searchers showed that Phoenix could form particles capable of infecting mammalian cells in culture. Infectivity was very low, presumably because host cells have evolved mechanisms to resist uncontrolled virus propagation, as has been repeatedly observed for retroviruses from experimental animals. "Phoeni...

MIT engineers probe spiders' polymer art

...t is water. The spider's silk-producing glands are capable of synthesizing large fibrous proteins and processing those proteins into an insoluble fiber. "The amazing thing nature has found is how to spin a material out of an aqueous solution and produce a fiber that doesn't re-dissolve," McKinley said. Lik...

Patients to benefit from novel technology revolutionizing high-speed molecular imaging

...) due to usage of a split–scanning detector design capable of dwelling more on the organ of interest. This, together with radiation collection angles larger than in existing technology, constitutes a radical departure from the conventional Anger camera," he detailed. Besides providing improved statistics lea...

Gardenia fruit compound starting point for diabetes therapy

...ur goal therefore was to discover a UCP2 inhibitor capable of working in intact cells, as such an inhibitor could theoretically represent a lead compound for agents aimed at improving beta cell function in type 2 diabetes." Study coauthor Chen-Yu Zhang's familiarity with traditional Chinese medicine led the...

K-Staters design and build a low-cost remote sensing tool for environmental studies

...the sensing tool/unmanned aerial vehicle should be capable of "flying low and slow" just a few feet above the ground. The onboard payload of digital cameras, spectral radiometers and other remote sensing instruments will produce high-resolution images and data about small groups of plants and their environme...

"We did not use a direct model of age-related macular degeneration," Scott said. "But we now know that when RPE is injured, it ca...

Taking the wrinkles out of motoneuronal disease

...enomous species has resulted in deadly neurotoxins capable of blocking neuronal communication. I am using our knowledge of the mode of action of these neurotoxins to design a selective motoneuron delivery system that could change our way of treating motoneuronal diseases."
