With record resolution and sensitivity, tool images how life organizes in a cell membrane

...fic, that tells you which component is which. I'll put on my chemist hat now. When a chemist says, 'I know what's there,' he or she means, 'I know chemically what's there.' I know that this is cholesterol or this is sphingomyelin or this is some other molecule. You need a way to do analytical chemistry, ...

Gene transfer using mutant form of good cholesterol cuts vascular plaque and inflammation

...the researchers used a "signal molecule" when they put the genes into the bone marrow. The signal molecule selectively goes into immune system cells called macrophages, which go into the arterial wall. "We examined the ability of both the wild type and the apo A-I Milano gene to move cholesterol out of...

Scientists use gene signatures to match cancer and other diseases with potentially effective drugs

...ther resistant or sensitive to glucocorticoids and put them through the Connectivity Map database, and it predicted that one of the best drugs would be rapamycin," said Armstrong, who is also an assistant professor of pediatrics at Harvard Medical School. "Then we tested rapamycin to see if it made the A...

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

...nse to the salt water. But when the researchers 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 s...

Tweedle coat fashions stocky flies

...pear compressed. "It's not a trivial matter to put a shell on from the inside," explained Steven Wasserman, a professor of biology who headed the research team. "An insect needs to build up the flexibility, strength and shape of each part before sealing the outside. If you've ever peeled a golf bal...

Light-sensitive photoswitches could restore sight to those with macular degeneration

...wrence Berkeley National Laboratory (LBNL) aims to put light-sensitive switches in the body's cells that can be flipped on and off as easily as a remote control operates a TV. Optical switches like these could trigger a chemical reaction, initiate a muscle contraction, activate a drug or stimulate a ner...

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

Report focuses on the role good microbes play in future medicine

... infections. Probiotics could also conceivably be put to use in preventing disease or thwarting autoimmune disorders. A number of these possibilities are being explored in research labs and hospitals around the world," says Richard Walker of the Food and Drug Administration, a co-chair of the steering ...

Predators prefer to hunt small-brained prey

Dr Shultz said: "When these findings are put into perspective, it makes sense that being clever should help individuals avoid or escape danger ?the larger-brained chimpanzees rarely feature in the diets of predators." "Some animals' ability to avoid being eaten by predators may be a contribu...

Leptin found to control appetite and limb development in frogs

...e frog gene. But once they solved those issues and put the gene into E. coli bacteria to make quantities of leptin, the frog protein turned out to be functionally very similar to the human version, Denver notes. "It would appear that leptin and its role as an energy balance indicator has been around a ...

Researcher studies, treats military with 'silent disease'

...ht," she said. "We like to talk to the patient and put them at ease, and say 'Look this is the story, let's work together.'" Having the disease doesn't end a military career. Military members who have it can still deploy, though not while they're undergoing treatment because it's so intensive. "When we...

Beauchamp discovered the spring in the mid-1990s when he noticed a yellow stain on the snow while passing over the Borup Fiord Pass in a helicopter. He eventually ...

Liebersohn's study is the first to put the travelers at the center of the "networks of knowledge" story, to make them "mediators in the global system for the production of knowledge," he said. According to Liebersohn, the naturalist-travelers worked back and forth from patrons at home to...

Lost in thought: Brain research

...ere resting.) "It is tempting," says Malach, "to put these findings in a broader perspective, one that veers away from traditional western thought, with its emphasis on self-control and for which 'someone is always minding the store,' and toward more eastern perspectives, in which the 'self must be aba...

Operations should be restricted to low tide and suspended during calving season, an exclusion zone should be monitored before any activity starts and marine work should cease if a...

Beekeepers work hard for the honey, despite changing tupelo forest

...say it is increasingly difficult to find places to put their hives. One reason is because the forest has taken a beating from more than 45 years of dredging of the Apalachicola for a river navigation project. The dumping of the dredged material has cut off many tupelo trees from their source of fresh w...
