Read moreResearchers Use Drug-radiation Combo to Eradicate Lung Cancer
In a study appearing in the October issue of Cancer Research, UT Southwestern researchers found that if they administered BEZ235 before they damaged the DNA of tumor cells with otherwise nontoxic radi...
Health and Medicine | Read moreNew System Tests Water Quality in Orbit
“Now they bring water back on the space shuttle and analyze it on the ground. The problem is there is a big delay. You’d like to be able to maintain iodine or silver [disinfectant] levels in real time...
Life Sciences | Read moreTumors feel the deadly sting of nanobees
In mice, nanobees delivered the bee toxin melittin to tumors while protecting other tissues from the toxin's destructive power. The mice's tumors stopped growing or shrank. The nanobees'...
Life Sciences | Read moreLost molecule is lethal for liver cancer cells in mice
Scientists at Johns Hopkins have discovered a potential strategy for cancer therapy by focusing on what's missing in tumors.Noticing the conspicuous absence of single-stranded genetic sni...
Life Sciences | Read moreDiscovery Could Help Feed Millions
The Northern Arizona University researcher and her colleagues at NAU and the University of Arizona identified a nontoxic chemical technology that when applied to rodents, caused infertility in rats, w...
Life Sciences | Read moreCapsules Encapsulated
When cells cannot carry out the tasks required of them by our bodies, the result is disease. Nanobiotechnology researchers are looking for ways to allow synthetic systems take over simple cell...
Life Sciences | Read morePitt vaccine to prevent colon cancer being tested in patients
If shown to be effective, it might spare patients the risk and inconvenience of repeated invasive surveillance tests, such as colonoscopy, that are now necessary to spot and remove precancerous polyps...
Health and Medicine | Read moreNew Catalyst Paves the Path for Ethanol-Powered Fuel Cells
The highly efficient catalyst performs two crucial, and previously unreachable steps needed to oxidize ethanol and produce clean energy in fuel cell reactions. Their results are published online in th...
Materials Sciences | Read moreWireless Microgrippers Grab Living Cells in ‘Biopsy’ Tests
In experiments that pave the way for tiny mobile surgical tools activated by heat or chemicals, Johns Hopkins researchers have invented dust-particle-size devices that can be used to grab and remove l...
Life Sciences | Read morePitt Researchers Create Nontoxic Clean-up Method for Common, Potentially Toxic Nano Materials
University of Pittsburgh researchers have developed the first natural, nontoxic method for biodegrading carbon nanotubes, a finding that could help diminish the environmental and health concerns that ...
Materials Sciences | Read moreTiny knights in shining armor - bacteria detoxify deadly seawater
Scientists now discovered that bacteria also protect marine animals from this toxic gas. A bacterial bloom detoxified a vast expanse of hydrogen sulphide-containing water off the coast of Namibia, bef...
Life Sciences | Read moreHope for Alzheimer’s Patients?
Alzheimer’s disease is the primary cause of age-related dementia. About 15 million people are affected by this neurodegenerative disease worldwide. It has so far not been possible to combat the causes...
Life Sciences | Read moreResearchers shed new light on catalyzed reactions
Rice University scientists on the hunt for a better way to clean up the stubborn pollutant TCE have created a method that lets them watch molecules break down on the surface of a catalyst as individua...
Life Sciences | Read moreFe-NHC-Kat - for non-toxic regioselective catalysis
Fe-NHC-Kat stands for a completely new class of catalyst. These iron catalysts are much more beneficial than conventional noble metal or nickel catalysts. They are nontoxic and less susceptible to ext...
