CT scan reveals ancient long-necked gliding reptile

...e a set of thin slices that had to be processed to obtain information about the animals. Even then, no single slice contained the entire skeleton. Post-scan processing produced an amazingly clear, if somewhat flattened, image of a small reptile with a long neck and swept back wings. Gliding behavior ev...

Nurtured chimps rake it in

...rrectly chose the rigid rake which enabled them to obtain the reward, indicating that both of these groups understood the physical properties of the two different rakes. The researchers then presented the same two groups with two identical ‘hybrid’ rakes. Each rake head had a rigid side made of wood (fu...

Mutating the entire genome

...ortionate because more mutant mice must be bred to obtain desired mutants, he says. Capecchi says the new technique could speed a National Institutes of Health effort to mutate all mouse genes in cell culture and create 900 new lines of mutant mice by 2010 – an effort NIH says “will be extremely useful ...

The mouflons of the Kerguelen archipelago

...id Denis Réale with a smile. “We were even able to obtain genetic material from the population of origin from the Vincennes Zoo. “We took the DNA from these samples, and looked at specific genetic sites,“ explained Renaud Kaeuffer. “We expected that the genetic diversity of this population of mouflons would...

Scientists close in on missing carbon sink

...st time that a team of scientists analyzed them to obtain a picture of sources and sinks of carbon on a global level. The research team compared the air samples to estimates of airborne carbon dioxide concentrations generated by the computer models. The scientists found that most of the models significan...

A cherry on top: Tart cherries may alter heart/diabetes factors

... that would be very difficult if not impossible to obtain in the diet." He continues, "We are interested in a whole-foods approach, using amounts of fruit that are relevant to human diets. We are enthusiastic about the findings that tart cherries conferred these beneficial effects at such a modest daily ...

DNA-damage test could aid drug development

...cts toxicity in humans, not animals, and you could obtain human bone marrow that's left over from medical procedures." "If you could change the micronucleus assay to have a human cell readout, that would be pretty amazing," says Samson. Down the road, she suggests, such a test might offer a new way to ex...

Thymus transplants gives hope to babies with fatal immune disease

...e would have died." For the procedure, surgeons obtain thymus tissue that usually is discarded from babies undergoing heart surgery. Since the gland is large and covers the heart in infants, surgeons must remove all or part of it to gain access to the heart. The removed thymus tissue is grown in culture ...

Scientists seek useful traits in wild cottons

...and cold tolerance. Scientists at Lubbock obtain seed from global cotton collections in small lots, sometimes as few as 10 seeds per lot. Before their work advances, they must turn a few seeds into more by growing plants in an environmentally-controlled greenhouse. Greenhouse manager and E...

Sleep quantity affects morning testosterone levels in older men

...the study raise the possibility that older men who obtain less actual sleep during the night have lower blood testosterone levels in the morning," said Penev. "Although the findings suggest that how long a person sleeps may be an indicator of age-related changes in important hormone signals in the body, fu...

Natural antibiotics yield secrets to atom-level imaging technique

...ssion is to use the kind of basic physical data we obtain from solid-state NMR spectroscopy to help interpret biological functions," Ramamoorthy said. The work is highly interdisciplinary, involving not only Ramamoorthy's lab and several other groups in the Chemistry Department, but also researchers from th...

OHSU surgeon implants donated tissue allografts

'Recently a number of new respiratory viruses have been discovered,' the Bonn lecturer explains. 'We presume that we will find antibodies in the blood samples ...

Nanotechnology meets biology and DNA finds its groove

...one day help underpin the ability of clinicians to obtain customized DNA profiles of patients. The new work is reported this week (Feb. 8, 2007) in the Proceedings of the National Academies of Science (PNAS) by a team of scientists and engineers from the University of Wisconsin-Madison. "DNA is messy,...

Newborn brains grow vision and movement regions first

Scientists clone mice from adult skin stem cells

...ative disorders where researchers are only able to obtain affected tissue from autopsies," says Fuchs. If on the other hand, scientists are able to generate embryonic stem cells from the skin of a patient, for example an Alzheimer's patient, these embryonic stem cells might be used in the laboratory to ...

Scientists use nanoparticle to discover disease-causing proteins

...rbed when samples are collected, researchers can't obtain an accurate picture of biochemical mechanisms related to illnesses such as cancer and heart disease. Tao and his research team used dendrimers because they can pass through cell walls efficiently with little disturbance to the cells and then label...

New species declared: Clouded leopard on Borneo and Sumatra

...dividuals. However, further studies are needed to obtain better population data. Habitat destruction is the cat’s main threat. The last great forest home of the Bornean Clouded Leopard is the Heart of Borneo, a wild, mountainous region of rainforest the size of Kansas. WWF recently released a report ...
