First Biodiversity Census of coral reef ecosystems in the NW Hawaiian Islands

... to explore coral reef biodiversity in the largest fully protected marine area in the world--the Northwestern Hawaiian Islands Marine National Monument. Led by the National Oceanic and Atmospheric Administration (NOAA) Pacific Islands Fisheries Science Center, with funding from NOAA's Coral Reef Conservat...

A new target for painkillers

...er 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 fish or s...

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

...meeting today (Sept. 11) in San Francisco. Once fully developed, the biodegradable absorbent wipe would contain nanofibers containing antibodies to numerous biohazards and chemicals and would signal by changing color or through another effect when the antibodies attached to their targets. Users would si...

Scientists find mutations that let bird flu adapt to humans

...s, says Kawaoka, will be required for the virus to fully adapt to humans, but it is not known how many mutations are needed for such a change. However, if scientists are able to continue to monitor and secure viral isolates from humans infected with bird flu, they may be able to map a mutation trajector...

Does natural selection drive the evolution of cancer?

The dynamics of evolution are fully in play within the environment of a tumor, just as they are in forests and meadows, oceans and streams. This is the view of researchers in an emerging cross-disciplinary field that brings the thinking of ecologists and evolutionary biologists to bear...

MIT designs portable 'lab on a chip'

...wards making an existing miniature "lab on a chip" fully portable, so the tiny device can perform hundreds of chemical experiments in any setting. "In the same way that miniaturization led to a revolution in computing, the idea is that miniature laboratories of fluid being pumped from one channel to anot...

First-time analysis reveals millions of Europeans left at risk from influenza

...ysis confirms that increasing vaccination rates is fully justified through a cost-benefit analysis. This model is a clear call to action for visualising our vaccination goals. I cannot stress enough the urgency of action for public health officials and governments across Europe to address this issue today ...

Advance helps explain stem cell behavior

...horses, mice or humans. Once the process is more fully understood, it should be much more feasible to influence and control it, researchers say. If the task were spinal cord repair, for instance, the goal would be to influence cells to become certain types of spinal cord cells. This area of "molecular me...

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

...things currently are being done. When this chip is fully developed, it will impact the way patients are monitored, and the way they receive therapy. It will supercede what is already out there." If there is a perfect path for a start-up company to take, Physiologic Communications has found it, Fahner-Vih...

Reading Shakespeare has dramatic effect on human brain

...and forces the brain to work backwards in order to fully understand what Shakespeare is trying to say. Professor Philip Davis, from the University's School of English, said: "The brain reacts to reading a phrase such as ‘he godded me' from the tragedy of Coriolanus, in a similar way to putting a jigsaw...

Too mellow for our predatory world

...T) is absent in predator-naïve animals but can be fully restored with experience. However, as the researchers found out, the flight distance of the reptiles does not sufficiently increase, which limits their ability to successfully escape from newly introduced predators (Proceedings of the Royal Society, ...

Technology for monitoring fetal oxygen during labor offers no apparent benefit

...e to know how effective it will be until it can be fully tested under clinical conditions," said Duane Alexander, M.D., Director of NIH's National Institute of Child Health and Human Development, which operates the network. The study, appearing in the November 23 New England Journal of Medicine, was con...

PLoS ONE is launched by the Public Library of Science

...munication of research findings an interactive and fully accessible process that gives greater value to what we do as scientists." PLoS ONE was first described to the research community back in June 2006, and the response to the proposal has been enthusiastic and sustained. Although PLoS ONE opened its d...

Getting to the heart of the heart

...evelop from very primitive embryonic stem cells to fully differentiated tissue, you have the potential to duplicate that process in the lab and make a tissue that a patient might need," says John Mayer, MD, a cardiovascular surgeon at Children's who is developing tissue-engineering techniques to create bio...

Long-term cancer risk follows stem cell transplant recipients

...uthors, "extended follow-up will be needed to more fully assess the incidence and risk factors for their development." ...

Human testis harbors HIV-1 in resident immune cells

... HIV-1. Virus produced from the testis culture was fully active as collected virus was able to infect permissive cells in culture. The finding that HIV-1 can replicate within testicular macrophages is significant because the testis represents a pharmacological sanctuary—many anti-retroviral drugs have ...

Restoring tamoxifen sensitivity in resistant breast cancer cells

...s of tamoxifen in cell cultures and in mice can be fully restored by the use of a compound called disulfide benzamide, or DIBA. The investigators confirmed their study hypothesis about DIBA's effect on tamoxifen resistance by using the compound in mice that were engineered to have tamoxifen-resistant tumor...

Cougar predation key to ecosystem health

...ory by deer, elk, or other grazing animals is more fully understood. In systems with wild ungulates, the sustainability of riparian habitats and biodiversity may require both predation on these herbivores as well as the fear of predation to further affect their behavior, the researchers concl...

Viral marker of human migration suspect

...ces in their evolutionary histories has never been fully tested. Shackelton and her colleagues analyzed 333 genetic sequences of the virus and reconstructed their evolutionary history. They then compared this history to the reconstructed history of human populations, based on mitochondrial DNA. "If ...
