FDA sees nanotech challenges in every product category it regulates

...ected in the next 5-10 years.” “Many of the first generation of nanotechnology products now on the market are in sectors where FDA’s statutory authority is weakest—areas like cosmetics and dietary supplements,” stated Project on Emerging Nanotechnologies Chief Science Advisor Andrew Maynard. “The Task Force re...

Hormone helps mice 'hibernate,' survive starvation

...rmone-receptor signaling pathway to craft the next generation of drugs to combat human obesity and other conditions.” Mammals on the brink of starvation normally shift their main fuel source from carbohydrates to stored fats, promoting survival during foodless periods. Some mammals also enter a hibernation-l...

Now, self-healing materials can mimic human skin, healing again and again

The next generation of self-healing materials, invented by researchers at the University of Illinois, mimics human skin by healing itself time after time. The new materials rely upon embedded, three-dimensional microvascular networks that emulate biological circulatory ...

Newly discovered antibody may be body's natural defense against Alzheimer's

...Alzheimer's and therefore a prime target for a new generation of disease-modifying treatments. To further confirm that these natural antibodies bind with oligomers, Dr. Relkin and his colleagues collaborated with Drs. Charles Glabe and Rakez Kayed from the University of California at Irvine, who had previou...

Electric fish conduct electric duets in aquatic courtship

... topics as mate choice and neural basis of pattern generation in these fish," explained Hopkins, noting that the next step in the research will be to decode the fish transmissions and unravel their meaning....

A first -- Hebrew University scientist observes brain cell development in 'real time'

...f Jerusalem has succeeded in observing in vivo the generation of neurons in the brain of a mammal. Dr. Adi Mizrahi of the Department of Neurobiology at the Alexander Silberman Institute of Life Sciences at the Hebrew University, used mouse models to study how neurons, or nerve cells, develop from an undiffere...

Philandering female felines forgo fidelity

...ows that more fathers are contributing to the next generation than we thought,” added Durant. “This is good news for cheetahs, and a reminder that future conservation strategies need to encompass large landscapes if females are to continue to have access to many males.” In addition to helping save cheetahs i...

More recycling on the farm could reduce environmental problems

...e of inorganic fertilizers and more on-farm energy generation from wind and fermentation of biosolids. It would also reduce overcropping and leakage from manure storage that contaminates groundwater. Yet despite similarities, Pearson's concept of regenerative agriculture is distinct from organic farming; for ex...

Technique monitors thousands of molecules simultaneously

... going to another electrode. This was done for the generation of acids and bases and applied to the synthesis of DNA and peptide polymers. But could this approach be used to make the more difficult to synthesize shaped molecules needed for mapping a receptor? This would require a diverse array of reactions to b...

Corals -- More complex than you?

Study shows continued success for new HPV vaccine against virus responsible for cervical cancer

...nd one of the study authors. But for the next generation of young women, a series of three shots of a new HPV vaccine marketed by Merck under the name Gardasil could make the difference in preventing cervical cancer. The vaccine targets HPV types 16 and 18, which cause about 70 percent of all cases of cer...

Slowing the racing heart

"Although adrenaline and other mechanisms that accelerate the heart rate have been well studied, mechanisms that might act as a brake are poorly understood," said Solaro. "Identification of th...

Scientists seek useful traits in wild cottons

...on fruit and their ability to lay eggs for another generation are good indicators of Lygus resistance, said Sheehan, who hopes to intensify her experiment in 2007. Raina King, a Texas Tech University graduate student, is working to develop 'cleaner' cottons that shed the small leaves (bracts) at the ba...

Fat overrides effects of vitamin C

Study shows isolation of stem cells may lead to a treatment for hearing loss

...become the next big epidemic affecting our younger generation though the effects won’t show until it is too late to treat. In addition to loud noise, certain cancer drugs or genetic factors can cause hearing loss in humans due to loss or faulty development of the sensory ‘microphones?(hair cells) inside the ea...

Drug-resistant bacterial infections serious complication after corrective eye surgery

...ts of MRSA keratitis after prophylaxis with fourth generation fluoroquinolones. Colonization of MRSA has been found in 1.5% of the general population, but as many as 9.4% of those were exposed to a healthcare facility. However, strains of MRSA are emerging in the community. These so-called community strains ...

When your brain talks, your muscles don't always listen

...om the neurons, the muscle fibers contract. In the generation of muscular force, the smallest controllable unit consists of an individual neuron and the muscle fibers it stimulates. We believe that our research is very important to our understanding of motor-control mechanisms in general and impaired control in...

Molecular differences between early and advanced melanomas could provide new drug targets

..., one of the NOX family of genes known to increase generation of ROS and to trigger angiogenesis. The scientists also found that in cells with greater Akt expression, there was an increase in impaired mitochondria-- the energy factories of cells. Their research showed, however, that these mutations in mitoc...

Scientists find new genes for Crohn's disease

...eactive oxygen species, which are important in the generation of a protective response against microbes, may lead to an increased risk of developing the condition. Particularly interesting to the authors was the association between Crohn's and variations in the ATG16L1 gene, which they found is essential for...
