Project shows need for better monitoring of river restoration

...der, an SNRE graduate student. While thus far it's tough to rate the ecological success, the good news is that there are many ways to improve the way project managers carry out and evaluate ecological restoration. First, Alexander interviewed 39 project managers in the three states about whether they viewe...

Scientists collaborate to assess health of global environment

...y by giving them the information they need to make tough decisions. A substantial body of work addressing specific aspects of the assessment will follow this month's release of the global synthesis report. A report on global biodiversity will be available in May; a report on desertification is due out in J...

New tumor-suppressor gene discovered

...ment of the fly's eye. Lai's team also tackled the tough challenge of discovering how the mats gene is able to suppress the growth of tumors. "We did not find many clues when we compared the sequence of the mats gene with the sequence of other genes in the public databases," Lai says. "But we did find a ...

Kids with chronic illness face difficult transition to adult care

...diatrician who may have saved their lives can be a tough transition. More than half a million children with special health-care needs will turn 18 this year, the first generation to reach adulthood since sweeping medical advances ensured an unprecedented number would survive congenital conditions that unt...

Tufts-NEMC researchers identify enzyme that activates cancer cell growth and invasion

.... This means that MMP-1 is not only cutting up the tough collagen matrix that surrounds cancer cells, it is also activating PAR1 to enable the cancer to invade into other tissues." The researchers identified several cell-penetrating compounds called pepducins that block activated PAR1 from triggering cance...

Moreover, the mechanism through which the organism becomes so pathogenic once the protective barrier of the skin is removed remains unclear. In their study appearing online on February 3 in advance of publication in the March 1 print ed...

Lupus Research Institute increases funding for innovative research

...tes of Health (NIH) funding mechanisms in the very tough fiscal climate that lies ahead," she said. "That's where the private sector most needs to kick in." "Predictions of minimal growth in Fiscal 2006 NIH research budgets are a wake-up call--and at the LRI we hear it loud and clear," Dowd added. The LR...

Jeans too tight? 50 percent of adults can blame their genes and not just diet and exercise

...exercise accounts for the other 50 percent. It's tough enough for Joe Six Pack to take off weight. But for those whose genes predispose them to be heavy, weight loss is going to be difficult really difficult and take extra effort. "We're not acknowledging the strength of genetic factors in our weight l...

First x-ray laser gets funding

...d very well, which is particularly notable in very tough budget times." Said Professor Keith Hodgson, director of the Stanford Synchrotron Radiation Laboratory (SSRL) at SLAC: "LCLS will be the world's first X-ray free electron laser and will provide a powerful combination of laser properties delivered at ...

Protein transformation gives new twist to medical research

...V. Lyz is a lysozyme, a protein that degrades the tough cell wall that covers bacterial cells. The name lysozyme means break-out enzyme as coined by Alexander Fleming, who was also the inventor of penicillin. Lysozymes are everywhere, Young noted. They are even in your tears, where they destroy ba...

New approach studying protein structure could advance drug development

.... Furthermore, high quality crystal structures are tough to attain, and only a limited number of proteins have documented crystal structures of the protein with and without a ligand present. "There is no other technique like this out there," said co-author Diane Rodi from Argonne's Biosciences Division,...

NIDCR launches unique initiative on oral biofilm

"We know that it's going to be tough to sequence the genomes completely or be certain about the origin of every gene,'" said Dr. David Relman, a scientist at Stanford University in Palo Alto, Ca. and a co-principal investigator on the project with Drs. Stephen Gill and Karen Nelson of T...

Tracking orangutans from the sky

...from 2,000 to 20,000--are outdated. Orangutans are tough to spot directly, so researchers traditionally count the nests they sleep in at night, which is time-consuming, especially when faced with the hip-deep muck and steep slopes of the rainforest floor. Instead, Ancrenaz and colleagues have developed a s...

Free radicals and fertilization: Study reveals egg protection secret

...hin layer surrounding the egg, hardening it into a tough coating. The process is complete about five minutes after fertilization. Wong showed this essential role by obstructing the function of Udx1. When its activity was blocked, the protective barrier didn't harden, leaving the embryo vulnerable. The auth...

Spider silks, the ecological materials of tomorrow?

...rposes. For example, major ampullate silk, a very tough silk with a tensile strength comparable to Kevlar, is used for the primary dragline or scaffolding of the spider's web. Minor ampullate silk with its very low elasticity is used to reinforce the web, while the strong and stretchy flagelliform silk fo...

Acid-resistant bug doesn't give in to alcohol either

...ton University in St. Louis has found surprisingly tough enzymes in a bacterium that "just says no to acid."Acid resistance is a valued trait for both pills and human pathogens. The bacterium Acetobacter aceti makes unusually acid-resistant enzymes in spades, which could make the organism a source for new ...

Endurance running may be key to evolution of human body form

This extensive system of springs in the leg and foot effectively store and release significant elastic energy during running, but t...

Mouse model of osteoarthritis

...he ends of the bones are covered with cartilage, a tough but smooth tissue that, like the oil in a car engine, reduces friction between the moving parts. In the most common form of arthritis--osteoarthritis--breakdown of this cartilage, which is called articular cartilage, means the bones rub together, cau...
