Fungal factories may save hemlock forests

..."This is a great one," she says, holding the clear plastic up to her face. Inside, a tree branch is speckled with white fluff. "It's growing really well," she says, handing it to Scott Costa. Costa brings the branch close to his eye. "Yes," he says, with a boyish grin, "this is a fungus success story." F...

Manual dishwashing study digs up dirt on dish cleanliness

...pared to ceramic plates, steel knives, spoons, and plastic trays, steel forks seemed to be the best home for bacterial contaminants. "The prongs of forks actually shield food from the action of scrubbing," Pascall said. "Taking extra time to wash forks is a good idea, especially those covered with sticky ...

Liposuctioned fat stem cells to repair bodies

Scientists produce neurons from human skin

...ysiology. The researchers used skin obtained from plastic surgery procedures. They subjected these skin samples to various treatments in order to extract neuron precursor cells, which they then proceeded to cultivate in vitro. Skin itself does not contain neurons, which are hosted in the spinal cord, but co...

Bumblebee house warming -- it takes a village

...task performance, the researchers glued a numbered plastic tag to the thorax of workers in three colonies. They observed and videotaped the incubation and wing fanning, or cooling, performed by individual workers under four temperature conditions ?cold, moderate, warm and hot. Temperatures ranged from 10.3...

Computer imaging assists with facial reconstructive surgery

...pper ear and chin in photographs could help facial plastic surgeons use computer imaging software to achieve ...d information in the article. It is essential for plastic surgeons to accurately analyze the face before surgery so that afterward, prominent facial features ...

Carnegie Mellon University research shows how sensory-deprived brain compensates

...ing arm with the expectation that the brain may be plastic enough to assist that arm in recovering motion. "We think that our well-designed model is extremely good for future in-depth studies of brain plasticity in response to changes in how an animal senses its environment. Ultimately, we want to un...

Study to explore using magnets to correct 'sunken chest'

...bone and a second magnet embedded in a lightweight plastic brace that the child wears under clothing. The attraction between the two magnets holds the brace in place. Because the internal magnet is placed just under the skin during an outpatient visit, the child can go home on the day of the procedure wi...

Phthalates now linked to fat, related health risks

...paint, pesticides, and plastics. Phthalates soften plastic tubing, PVC, and are also used in the coating of some timed-release medicines. More than 75 percent of the United States population has measurable levels of several phthalates in their urine, according to the study. "Unfortunately, there’s sti...

Darwin's famous finches and Venter's marine microbes

...her surprising finding was just how innovative and plastic the different families were, even with these core residues, as one or another family had found ways to eliminate any but one of the 10 key residues. Using structural modeling, and patterns of sequence conservation, Kannan was able to show that loss o...

Cancer-killing invention also harvests stem cells

...ly than other cells, King's group coated a slender plastic tube with selectin. They then did a series of lab experiments, both in vitro and in vivo using rats, with this selectin-coated tube to filter the bloodstream for stem cells. It worked, and the King Lab discovered that they could attract a large num...

Eating with our eyes: Why people eat less at unbused tables

...college parties could encourage (or require) fresh plastic glasses for each drink and that the glasses be stacked as they accumulate for each person; dinner parties could use fresh glasses for refills while empty glasses, or even empty bottles, are left on the table. ...

Researchers reveal structure of protein altered in autism

...arly in development when the infant brain is still plastic and formative. Therefore, by understanding the structural mutations that affect neurotransmission during development, new leads into drug therapies may emerge. “We really don’t know what causes autism, but this research represents a solid start...

One species, many genomes

...till, it is surprising that Arabidopsis has such a plastic genome. In contrast to the genome of humans or many crop plants such as corn, that of Arabidopsis is very much streamlined, and its size is less than a twentieth of that of humans or corn—even though it has about the same number of genes. In contra...
