Studies find general mechanism of cellular aging

...for studies of aging, Sharpless said. "If you were going to calorically restrict yourself or take green tea or resveratrol every day for years in an effort to prevent aging, wouldn't you like some evidence that these not entirely benign things were having a beneficial effect? Now we have a biomarker that c...

Mysterious 'neural noise' actually primes brain for peak performance

... think the way everybody thinks about the brain is going to be in these terms." Not all of Pouget's neurons are in agreement, however. "…but I've been wrong before," he shrugs....

Fast-freeze snapshot yields new picture of nerve-muscle junction

Genetic surprise confirms neglected 70-year-old evolutionary hypothesis

...ly dismissed the moving-gene hypothesis. "We knew going into this that it was a risky experiment," says Ma...ld Masly what his analysis turned up. "You're not going to believe this, but you're right," said Jones. "It's not on the fourth chromosome. It's on the thir...

Artificial cornea offers better results for infants, some blind patients

...r so, the patient will see as well as they're ever going to see. While astigmatism often limits the quality of vision with traditional corneal transplant, this new device produces no astigmatism and a clearer image." Aquavella evaluated the recent progress in an unusual study, with himself serving as th...

Taking 'chips' to the next level of gene hunting

...ifferentiate the top and bottom layers. Next we're going to try adding another layer reading diagonally" to triple the amount of genomic information packed onto the tiny chips. ...

New system could drastically reduce herbicide use

...ors that go all the way around the machine, "we're going to try and use only the camera vision for navigation," said Jeon, "which makes it a lot more difficult." The robot stands a little more than two feet tall, is 28 inches wide and almost five feet long. He can travel about three miles per hour and m...

A new target for painkillers

... to a lower level than ever before. No one drug is going to fully treat all pain, so having a new way is like having a backup catcher if the first catcher misses the ball." How the Study was Performed The toxins in the study come from two cone snail species that eat worms, unlike relatives that eat ...

Biodegradable napkin -- featuring sensitive nanofibers -- may quickly detect biohazards

...aid. "As you do that, antibodies in the fabric are going to selectively latch onto whatever pathogen that they match. Using this method we should, in theory, be able to quickly activate the fabric to detect whatever is the hazard of the week, whether it is bird flu, mad cow disease or anthrax." Frey and h...

First biomarker for human sleepiness identified in fruit flies

... debt, but for a good diagnostic test we're likely going to need more than one biomarker," Shaw says. "So we're going to continue to use the processes that we've developed to look for other substances that change in co...

Did 'ABCs' cause Uganda's fall in HIV rates?

...that abstinence will allow young women to focus on going to school, controlling their relationships, and becoming socially empowered. Yet the reality for many young women in Uganda, they say, is that social circumstances drive them into transactional or commercial sex to pay for, among other things, schoo...

What's next for gene therapy? Plastic

... in chemical engineering, "typifies the way we are going to educate students in the future," Long said. "He is an engineer working in chemistry on gene therapy. He collaborates with researchers in the Virginia Tech-Wake Forest School of Biomedical Engineering and Oak Ridge National Laboratory. ...

Protein 'fingerprint' in spinal fluid could spot Alzheimer's disease

... "There's a federally funded, multicenter trial going on right now that involves many more patients, in which many enrollees will undergo spinal taps and brain imaging," Relkin said. "We hope to link into that effort to expand on these findings." The dream of a highly accurate Alzheimer's disease test...

Hope for major advance in fighting world killer disease

...medical intervention costs more than US$½ it's not going to be viable in developing countries. Our test is quick, robust and cheap. At a workshop we held recently at Anna University, more than 30 people, ranging from technicians and students to clinical professors, had the opportunity to perform the te...

Does natural selection drive the evolution of cancer?

...pulations are evolving," Maley says. "Evolution is going on in the tumor. So let's think about how we might want to influence that evolution. Can we push it down paths that might be more beneficial to us?" One idea might be to develop new drugs that would act as benign cell boosters. Such drugs would sp...

Researchers barcode DNA of Venice museum's vast fungi collection

...n the taxa from which it is sampled. "If you're going to cross-compare species, you've got to amplify the same region," said Sarah Bergemann, the post-doctoral researcher in ecosystem science who is heading the lab analysis work at UC Berkeley. Bergemann is working with Amy Smith, staff research associa...

Paramecia adapt their swimming to changing gravitational force

Embryonic selection of sex avoids conceiving blind children

...rom the disease with the consequent possibility of going blind. This is because, in order to select healthy embryos in a manner that does not involve sex selection, it would be essential to know the exact mutation in the chromosome, something which has not been achieved in this particular case. This emb...
