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

...nant. "We're probably still a few years away from having this ready for the real world," Frey said, "but I really believe there is a place for this type of product that can be used by people with limited training to provide a fast indication of whether a biohazard is present." ...

Genetic study of Neanderthal DNA reveals early split between humans and Neanderthals

... the Neanderthal suggests the low likelihood of it having occurred at any appreciable level." According to...searchers were able to analyze enough data without having to sequence the entire Neanderthal genome. ...

Older men treated for early prostate cancer live longer than those who are not

... group of 12,608 (28.3 percent) were classified as having received "observation" and did not undergo surgery, radiation or hormonal therapy. During the 12-years of follow-up, researchers found that the patients who received treatment had a 31 percent lower risk of death. In the observation-only group, 37...

Leading reason for corneal transplants comes into focus

... in the United States will eventually benefit from having the genetic basis of their disease identified and gene therapies developed. At present, corneal transplantation is the only solution for those severely affected. ...

Hope for a more effective and less toxic cancer drug

...the new drug will prove to be more effective while having fewer side effects." The findings of the scientific assessment team are published in the 13 November 2006 issue of the prestigious international journal Cancer Cell. ...

Does missing gene point to nocturnal existence for early mammals?

...ow the functions of the two melanopsins differ but having different cone genes or 'opsins' allows vertebrate...nd so provide clues as to the implications of only having one melanopsin gene. "The two genes and their associated proteins have been maintained in vertebr...

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

...f this 23-protein screen suggests that IVIg may be having a positive impact on underlying disease processes." And while a standard test for spotting early Alzheimer's disease is not in doctors' offices today, it could be in the not-too-distant future. "These findings speak to the practicality of using b...

A fisheye view of the deadliest breast cancer

...se, with fewer than half of those diagnosed today having a five-year prognosis for survival. To find out what drives this most aggressive of human breast cancers, and to rapidly screen for drugs that might stop IBC, researchers at the University of California, San Diego (UCSD), have come up with an unlike...

Nanotech tools yield DNA transcription breakthrough

...o hold, stretch and twist a single molecule of DNA having a single start site for transcription. They then read out changes in the conformation of the DNA molecule in real time as transcription occurred. The researchers showed that the molecular machine responsible for transcription unwinds adjacent DNA seg...

Chemical tests of cell growth enter third dimension

...ts can run for up to two weeks without researchers having to replenish the growth medium. "If you replenish the medium, you could essentially grow cells indefinitely," Yang said. The second new technology to come from Yang's lab is a microfluidics platform that allows for testing of many types of cells or...

Pressured by predators, lizards see rapid shift in natural selection

... the opposite: Survivors were now characterized by having shorter legs on the experimental islands as compared to the control islands. The behavioral shift from the ground to higher perches apparently caused this remarkable reversal, Losos says, adding that behavioral flexibility may often drive extremel...

New dyslexia theory blames 'noise'

...mix up your letters (one of many possible symptoms having to do with word recognition, directional ability and decoding of symbols). What is known is that dyslexia affects millions of children, with estimates of its incidence ranging from 5 to 15 percent. Sperling, who conducted her research as a do...

New HIV statistics indicate increasing toll of AIDS on African American community

...e increasingly disproportionate impact HIV/AIDS is having on the African-American community: Eliminate marginalization of, and stigma and discrimination against, black gay and other men who have sex with men (MSM). African-American MSM is the population hardest hit by HIV, with diagnosis rates twi...

Tiny bones rewrite textbooks

...had ever trodden on New Zealand soil, despite them having thrived so widely in other lands. The fact that even one land mammal lived there, at least 16 million years ago, has put paid to the theory that New Zealand's diverse prehistoric bird fauna had evolved there because they had no competition from lan...

Flu shot effective against drifted influenza, nasal spray vaccine less so

...onto in a 1970 influenza vaccine study. Without having children in their study, Monto and Ohmit can't tell whether the two vaccines would have conferred different protection in 2004-05 in that age group. However, data from a study conducted in 2004-05 in children aged 6 to 59 months by MedImmune, sugge...

High tech help to prevent further heart disease

Researchers at the University’s Rockhampton campus are developing an on-line outpatient rehabilitation service for people who have had heart surgery to see if it improves health outcomes by reducing the risk ...

Microbe fixes nitrogen at a blistering 92 C

...at 90 C. The genetic analysis shows FS406-22 as having one of the deepest-rooted genes and the most primordial characteristics in terms of gene sequence, Baross says. "We propose that among diazotrophic archaea, the nitrogenase from FS406-22 might have retained the most ancient characteristics, possib...

PNAS study reveals why organs fail following massive trauma

...changed by trauma were listed in the literature as having a role in T cell function. What emerged was a map of the likely functions of hundreds of genes and proteins related to T cell post-trauma dysfunction, and their likely partners in signaling pathways. The final step was to demonstrate that the protein...

Dragonfly's metabolic disease provides clues about human obesity

...mans. "Metabolic disease isn't some strange thing having just to do with humans," said Marden. "Animals in general suffer from these symptoms." The work is also novel because it links metabolic disease to a supposedly harmless parasite living in the dragonfly's gut. The parasites, known as gregarines,...

Cardiologist's 'living chip' changes science of disease monitoring

...would not suspect an issue until the patient began having symptoms or underwent pre-scheduled testing at a routine visit. Catching the problem earlier means the patient remains healthier, and greatly lessens the chance of a hospital stay. The initial application for this technology is expected to involve ...
