Weapon performance determines mating success in the collared lizard

...fitness than body size and weapon size. The study finds that bite-force performance was a strong predictor of reproductive success. However, no size measure was correlated with any estimate of mating success or with potential reproductive output. These results counter the conventional wisdom that bigger i...

Modifications render carbon nanotubes nontoxic

...y less toxic to begin with. Moreover, the research finds that nanotubes, like buckyballs, can be rendered nontoxic with minor chemical modifications. The findings come from the first toxicological studies of water-soluble carbon nanotubes. The study, which is available online, will be published in an upco...

Study provides insight into cellular defenses against genetic mutation

...nked to CBP80 are targeted for NMD when a ribosome finds an early stop codon. Most recently, the Nature paper demonstrated for the first time that CBP80 works by activating a protein factor known to drive NMD called human up-frameshift (hUpf) protein 1. A Matter of Spacing Immature mRNA is made of bot...

Hand sanitizer gel works

Randomized trial finds reduced spread of GI infections in families with children in day careUsing an alcohol-based hand sanitizer gel significantly reduces the spread of gastrointestinal infections in the home, according to a study in the September issue of Pediatrics. In...

Oysters: The natural way to protect our shores

...blished in the latest issue of Restoration Ecology finds that in coastal Louisiana, oyster reefs help to deter erosion. Oyster reefs are self-sustaining, and are additionally attractive because they use native materials, have the potential for long-term growth, and contribute to overall ecosystem stabilit...

University of Delaware researchers develop cancer 'nanobomb'

...anotubes and nanoparticles intact. If the material finds its way to the kidney or accumulates in the blood vessels, the nanoparticles might cause blockage and create problems, Panchapakesan said. Furthermore, the nanobomb route is probably the only way to use nanotubes without any cytotoxicity as the nanot...

Ancient anthropoid origins discovered in Africa

...he larger eyesocket of a nocturnal animal. "These finds seem to indicate that Biretia megalopsis must have had very large eyes, and so was likely nocturnal," said Seiffert. "This has never been documented in an early anthropoid. The simplest explanation is that Biretia's nocturnality represents an evoluti...

Nanoparticles, nanoshells, nanotubes: How tiny specks may provide powerful tools against cancer

...with genetic damage. The liposome-antibody complex finds the cancer cell by binding to the transferrin receptor, which is present on the cancer cell surface in high numbers. When this happens, the p53 "payload" moves into the tumor cell. "If we are going to have an effective cancer therapy, we have to b...

Scientists observe how a close bond activates the immune system

...ays Dr. Dustin. Once a T cell's antigen receptor finds an antigen match, the T cell forms an immunological synapse with a dendritic cell through which it queries the dendritic cell for additional information about the antigen and its source in the body. Is the antigen a danger or simply a harmless food p...

Cattle grazing may help rather than hurt endangered species

...lished in the latest issue of Conservation Biology finds that cattle grazing plays an important role in maintaining wetland habitat necessary for some endangered species. Removing cattle from grazing lands in the Central Valley of California could, inadvertently, degrade the vernal pool habitat of fairy s...

Missing fossil link 'Dallasaurus' found

...on display at the Dallas Museum. Major dinosaur finds are frequently the result of creatures dying in groups through flooding or drought, situations that lend themselves fairly well to more complete preservation and conservation of their bones, and much slower deterioration. Mosasaur fossils, in contras...

Why we give: New study finds evidence of generosity among our early human ancestors

...w study examines the origins of holiday giving and finds that our early human ancestors were frequently altruistic. "Reciprocity is arguably the foundational basis of cooperation in humans," writes Michael Gurven (University of California ?Santa Barbara). "A core feature of reciprocity is the contingent ...

Tracking the memory trace

... based on his most recent report on the topic that finds a memory trace in Drosophila or fruit flies is formed in a pair of neurons called the dorsal pair medial neurons, but only 30 minutes after the fact and only through the mediation of a gene called, ironically, amnesiac. (A memory trace is a chemical ...

UCSD study finds anthrax toxins also harmful to fruit flies

...y contract the anthrax disease. However, the study finds that fruit flies can be used to test the effects of a single virulence factor, such as the LF or EF toxins, on signaling pathways shared by flies and humans. Guichard and her co-authors applied lethal factor toxin to fruit fly embryos and larvae and...

Wisconsin scientists discover a master key to microbes' pathogenic lifestyles

...'s spores. It senses temperature, and when a spore finds itself at a comfortable 37 degrees Celsius, the body temperature of a human or other animal, it kick starts a genetic program that transforms the fungi into pathogenic yeasts. "This is a global regulator that sends signals down a molecular chain of ...
