...easure skin and bones, which couldbe used to treat burn victims or patients who have suffered severedisfigurements, may soon be a reality using inkjets which can printhuman cells.Scientists at The University of Manchester have developed thebreakthrough technology which will allow tailor-made tissues and b...

DNA Recombination and Repair—A New Twist to RecA Function

...econds—it takes for an individual RecA molecule to burn one ATP. This implies a filament organization in which every RecA molecule hydrolyzes ATP in synchrony with the sixth RecA molecule to its left and the sixth RecA molecule to its right. The authors note that there are approximately six RecA molecule...

Duke engineers develop new 3-D cardiac imaging probe

...tic treatment devices such as ablation probes that burn off damaged cells that cause an irregular heart beat. Clinicians must repeatedly and painstakingly reposition the 2-D probe during treatments so, instead, they use fluoroscopy (X-ray movies) to guide the placement of the treatment devices. However, t...

Findings have implications for tracking disease, drugs at the molecular level

...ff. "The gold particles, however, do not blink or burn out, even after hours of observation, and the brightest ones emit much more light than do molecules," he said. "We now have the ability to see single nanoparticles under conditions where people usually look at thousands or millions of stain molecules...

Atmosphere may cleanse itself better than previously thought

...ls called hydrocarbons, which are produced when we burn organic matter such as wood or fossil fuels. The atmosphere has three main ways to cleanse itself of such pollutants, two of which are relatively direct: either water droplets in clouds absorb them and rain them out, or sunlight strikes them and the ...

Grass makes environmentally friendly biofuel

... by farmers and burned in modified stoves built to burn wood pellets or corn, says Jerry Cherney, the E.V. Baker Professor of Agriculture. Burning grass pellets hasn't caught on in the United States, however, Cherney says, primarily because Washington has made no effort to support the technology with subs...

Key to elephant conservation is 'in the sauce'

...rican elephants have in common? They both feel the burn of chilli peppers, the key ingredient for resolving human-elephant conflicts in Africa while raising money for farmers and conservation. Supported by the Wildlife Conservation Society (WCS) and other groups, the Elephant Pepper Development Trust (EP...

Fat's fate depends on its source

...affects their physiology. New fats are required to burn fat normally and to maintain glucose and cholesterol levels within the normal range. "These findings underscore the importance of a balanced diet for healthy metabolism and weight loss," he added. The results further suggest that specially engineer...

Program finds lost genes in nematode genome

...ent, and the willingness to work for ten years and burn a lot of computer power, they'll come up with a machine that can beat the world champion. The same principal applies to developing a machine that can reveal the mysteries of our genes. In this case, the necessary investments have been made, but since...

Researchers discover mechanism for multiplying adult stem cells

...althy tissue." "This could be very beneficial for burn victims," Jaenisch adds. Researchers in his lab are also exploring whether activating Oct4 in somatic cells, such as skin cells, would make it easier for these cells to be reprogrammed when used as donors for nuclear transplantation. If so, it may h...

Insulin pulses keep the liver lean

... cells to take up glucose from the bloodstream and burn it for energy. In the liver, insulin promotes the synthesis and storage of lipids and carbohydrates and blocks their breakdown and release into the bloodstream. A failure to make or respond to insulin in people with diabetes causes blood sugar levels...

The findings, from a study carried out in Guizhou province, contradict the previous belief that the disease was caused by people burning fluoride-rich coal in indoor stoves without chimneys. Because of t...
