NC State researchers redesign life for Mars and beyond

...ual habitats. Moreover, there could be deleterious side effects to this type of genetic manipulation. What's important, the researchers say, is the fact that P. furiosus and other extremophiles might be able to lend their beneficial traits to plants sometime in the future. "This is very fundamental resea...

Scientists develop nanotech-laser treatment that kills cancer cells without harming healthy tissue

...ts often lose their hair and suffer numerous other side effects. For us, the Holy Grail would be finding a way to selectively kill cancer cells and not damage healthy ones." Nanotechnology For the PNAS experiment, Dai and his colleagues used a basic tool of nanotechnology--carbon nanotubes, synthetic ro...

Many smokers fail to quit after cancer diagnosis

...r treatments may be reduced in continuing smokers, side effects of treatment may be exacerbated, and survival rates are lower. Quality of life (QOL) is also better in nonsmokers. For example, multiple studies found that compared to nonsmokers, current smokers had significantly worse physical and psycholog...

Researcher uncovers details of how cancer spreads

...ell activity." That, in turn, would alleviate drug side effects. Guan and his colleagues used a cultured cell line to study cancer, which are mouse cells grown in the lab for research purposes. The researchers used these cells to create a model system for cancer cells, which means its basic pathway exist...

New discovery: If it weren't for this enzyme, decomposing pesticide would take millennia

...el catalytic activity of the enzyme may be a lucky side reaction of an enzyme that evolved to act on some natural substance yet to be identified." Horvat carried out the work in Wolfenden's laboratory by analyzing what happened to the pesticide's residue at various temperatures and then extrapolating the...

HIV mortality in India drops with introduction of generic antiretroviral therapy

...ia, can arise from antiretroviral use. But are the side effects serious enough to discourage patients from continuing ART? "No. Benefits of HAART outweigh the toxicities, based on our experience in our patients," said lead author Nagalingeswaran Kumarasamy, PhD, of the YRG Centre for AIDS Research and Edu...

Chatterjee and Templin fed Microraptor's flight data into a computer simulation that they have previously used to successfully analyze the flying abilities of pterosaurs and Ar...

Breath of the dragon: ERS-2 and Envisat reveal impact of economic growth on China's air quality

... in nitrogen dioxide levels seen is an unfortunate side effect of economic success. China's industrial boom has seen it become the world's largest consumer of copper, aluminium and cement and the second bigger importer of oil. Car ownership within the country has been doubling every few years. "China's ...

They will be evaluated for brain function one month and six months after the procedure to see if it is improved compared with historical data on the brain function of children of similar age who suffered a similar injury. Safety trials inv...

New GM mosquito sexing technique is step towards malaria control, report scientists

Plant defenses prompt bacterial countermeasure in the form of 'island' DNA excision

...mes that, when switched on, snip the DNA on either side of the island, resulting in the excision of the entire island from the genome. The researchers found that this excision occurs in response to a so-called hypersensitive resistance reaction by the plant . The specific plant signals that are sensed by ...

Compound from marine bacteria shows potential as multiple myeloma therapy

In some patients, the disease can be resistant or become resistant to bortezomib. Because NPI-0052 and bortezomib attack the same intracellular target in different ways...

New understanding of regeneration gained by Forsyth scientists

...he ability of previously adjacent cells (on either side of the cut) to adopt radically different fates, as is the case with planaria where the cells have to decide whether to build a head or a tail, could be due to long-range signaling, which allows the determination of position relative to - and the iden...

Implantable pumps extend lives of patients too sick for transplant

But when the damage causes stalled transcription this site is inside the RNAPII, which has closed itself around the two strands of DNA with a "clamp module." Indeed, the researchers found th...
