Remote control flies? Fly behavior controlled by laser light

...ate the lock, and laser light was the trigger that brought the key to the lock. For the lock, the researchers used an ion channel, or a pore-forming protein that allows charged particles to pass through a cell membrane. The small molecule ATP activates the ion channel chosen by the researchers, so ATP becam...

Bugs, even 'bad' ones, can be educationally beneficial, new book says

...urope when the French naturalist Leopold Trouvelot brought them to use in silk culture experiments. A few escaped as caterpillars and their descendants thrived, leading to rampant defoliation 20 years later. Such destruction has led people to devise various methods to exterminate bad bugs. "The least creat...

Beneficial Beetles Battle Pesky Saltcedar

...essive weed. Also known as tamarisk, saltcedar was brought into the United States in the 1800s to help control erosion. By the mid-1900s, however, saltcedar had become an out-of-control pest, crowding native plants, such as cottonwoods and willows, along streambanks and river channels throughout the American...

Leprosy genome tells story of human migrations, French researchers report in Science

...spread Leprosy to West Africa, and the slave trade brought the disease from West Africa to the Caribbean and South America, the study suggests. Europeans also introduced leprosy to North America. "Colonialism was extremely bad for parts of the world in terms of human health," said Cole. The disease, caused...

Climatologists discover deep-sea secret

...tic Ocean could already be adapting to the changes brought about by global warming in the same way as it adapted to climate changes in the past. The waters in the southern hemisphere are less salty than those in the northern hemisphere, and this freshwater in the south sinks to the ocean floor and is transpo...

Census of Marine Life explorers surprised by diversity, density of Arctic creatures

... chief scientist on the voyage. "Several creatures brought aboard the Healy are unfamiliar to expedition experts and may well prove new to science." Early findings amid several thousands specimens and images include suspected new species of jellyfish and benthic bristle worms, and the first squid and octopu...

Best research work in the area of wine growing

.... The V Iberian Congress of Horticultural Science brought together researchers and experts over a number of days to debate current horticultural topics. Amongst other aspects discussed were themes such as food quality and safety, conservation and use of horticultural biodiversity, conservation of the enviro...

High-powered gene profiles provide clues to genes involved in common form of lung cancer

...sis. In recent years, technological advances have brought new precision to the search for gene abnormalities associated with cancer. In the current study, Dana-Farber researchers used two forms of microarray technology to bring such abnormalities into focus. Using tumor samples from 44 NSCLC patients and 3...

MIT engineers an anti-cancer smart bomb

...e of Nature, with an accompanying commentary. "We brought together three elements: cancer biology, pharmacology and engineering," said Ram Sasisekharan, a professor in MIT's Biological Engineering Division and leader of the research team. "The fundamental challenges in cancer chemotherapy are its toxicity ...

Program finds lost genes in nematode genome

...l Sciences. Michael Brent Michael Brent Brent has brought his bioinformatics skills to many genomes, including those of mammals, other nematode species and most recently the fungus Cryptococcus neoformans. Brent's approach to gene prediction stands traditional genome annotation on its head because it starts...

Revueltosaurus skeleton unearthed at Petrified Forest upsets dinosaur tale

...re from Revueltosaurus until the next day, when he brought a colleague to the site and she picked up a jaw with teeth. During May and June of 2004, Parker, Irmis and their coauthors excavated one complete Revueltosaurus skeleton from the 6-square meter quarry they dug, plus bones from more than a dozen other...

UI researcher studies deafness in fruit flies, humans

...e leads to complete deafness in fruit flies -- has brought scientists one step closer to understanding how such mutations result in inner-ear abnormalities and deafness in humans. "Myosin VIIA was one of the first human hereditary deafness genes to be identified. But it is not clear exactly how this molecul...

Agilent Technologies introduces high-capacity human protein removal system for proteomics research

Study: Well-known protein helps stem cells become secretory cells

...nstitute for Basic Biomedical Sciences. Curiosity brought Andrew and Elliott Abrams, then a graduate student, to focus on secretion in the salivary gland, the largest glandular organ in the fruit fly embryo, approximately six years ago. In humans and in fruit flies, the gland secretes saliva, a fluid contai...

Genetic links could unlock clues to leading cause of blindness

...e these primates are the descendents of 50 monkeys brought to live on a Puerto Rican island just before World War II. The free-ranging monkeys on the island have multiplied to near 1,500, but because the rhesus monkeys are not native to the area, they could mate only with each other. This inbreeding has pred...

Researchers use 3-D imaging system to unveil swimming behavior of microscopic plankton

...they form patches as more and more individuals are brought in with the horizontal currents and concentrated in the downwelling zone. The scientists say the ecological implications of the zooplankton's depth-keeping behavior carry far-reaching consequences for predatory fishes, whales and humans. Predators ...

International Team Determines Geographic Origin of Leprosy

...oncluded that North Africans or Europeans probably brought the disease to West Africa. Compared with other disease-causing organisms, M. leprae has very few SNPs ?only one in every 28,400 letter pairs. The rarity of SNPs is an indication of extreme genetic stability: all the strains of leprosy throughout th...

Unexpected lock and key mechanism found for the assembly of tumor blood vessels

...." The research team discovered that the integrin brought the endothelia, the inside part of a blood vessel, together to bind with vascular smooth muscle, the outer portion of a blood vessel. Blood vessels only work when both endothelia and vascular smooth muscle are bound together. Previous work on integri...
