Not-for-profit publishers call NIH public access rule a missed opportunity

...ogle to crawl the journals' full text articles and link to the final published articles residing on the journal websites. This would offer significantly more assistance to those seeking medical research results than a database of NIH-funded manuscripts can provide. This public-private partnership would be...

Epstein-Barr virus protein crucial to its role in blood cancers

... Pennsylvania School of Medicine have identified a link between a critical cancer pathway and an Epstein-Barr Virus (EBV) protein known to be expressed in a number of EBV-associated cancers. Their findings demonstrate a new mechanism by which EBV transforms human B cells from the immune system into cancer...

Defensins neutralize anthrax toxin

Their findings demonstrate a new mechanism by which EBV transforms human B cells from the immune system into cancer...

Fleshing out the genome

...way to distinguish a bathroom from a boardroom, to link genomic features to cell function. A national consortium of scientists led by BIATECH, a Seattle based non-profit research center, and Pacific Northwest National Laboratory (PNNL), a Department of Energy research institution in Richland, Wash., now ...

Increased risk of osteoporosis associated with gene that one in five people have

...in the Division of Bone and Mineral Diseases. "The link to estrogen suggested that the gene could also affect bone density. No one had ever investigated that possibility, so we set up a study to evaluate the relation between bone density and variations of the CYP1A1 gene." The researchers studied 156 wom...

Microbial forensics: The next great forensic challenge

...ginal crime scene could be difficult to locate and link to suspects," Murch said. Additionally, the biological and ecological complexity of most biothreat agents present forensic microbiologists with a number of significant analytical and interpretive challenges. "It is doubtful that any one single techn...

Nanoparticles offer new hope for detection and treatment

...e researchers equipped them with tiny "hooks" that link only to complementary "loops" found on cells in newly forming blood vessels. When the nanoparticles hooked the "loops" on the new vessels' cells, they revealed the location of the tumors. Nanoparticles are particularly useful because of their adapta...

Love's all in the brain: fMRI study shows strong, lateralized reward, not sex, drive

...dictions, yields "remarkable implications"; autism link Aron reported that, using functional magnetic resonance imaging (fMRI) and other measurements, he and his colleagues found support for their two major predictions: (1) early stage, intense romantic love is associated with subcortical reward regions ...

Two are better than one

... the cancer cells to two different antibodies that link up to HER2 receptors. In a synergistic action, the antibodies were shown to cooperate rather than compete for distinctly different attachment points on the architecture of the receptors, resulting in the assembly of a large, springy molecular scaffol...

NYU and MSKCC research provides model for understanding chemically induced cancer initiation

...iously linked with cigarette smoke. This molecular link between chemical DNA damage and cigarette-associated lung cancer has been called the "smoking gun." In the study, the conformational switch discovered by the research team entails a change in the conformation of a carcinogen-damaged site in a DNA mo...

Master gene controls healing of skin in fruit flies and mammals

...nsect cuticle and mammal skin. "The proteins that link together to form the insect cuticle and stratum corneum--the outer layer of mammal skin--are completely different," says McGinnis. "So it is remarkable that flies and mammals share an ancient conserved pathway to construct and repair the body envelop...

Innovative collaboration brings Arctic science into the classroom

This is Dr. Holmes' second year of participating in TREC. During their expedition, Holmes and Clapp will have daily communications with students and the ...

Molecular thermometers on skin cells detect heat and camphor

...ince keratinocytes, unlike neurons, have no direct link with the central nervous system. Keratinocytes do, however, touch nerve fibers, and it may be through these contacts that the signals are communicated. Investigations into this possibility are ongoing. ### To read the article, "Impaired Thermosensa...

Structure-building cell signals also may influence learning and memory

... learning and memory. These findings, the first to link these molecular semaphores to this important nerve cell function, appear in the May issue of Nature Cell Biology, published in advance at the journal's website on April 10th. While the study's results are not immediately applicable to treating disea...

Remote control flies? Fly behavior controlled by laser light

Ed : Don't miss out the cool movies, link at the end of the press release! Yale University School of Medicine researchers have found a way to exercise a little mind control over fruit flies, making the flies jump, beat their wings, and fly on command by triggering genetic "remote controls"...

Just before he came to Virginia Tech in August 2004, Kulkarni and his collaborators at Princeton solved the mystery. Using bioinformatics and modeling, Kulkarni drafted ...

Scientists discover global pattern of big fish diversity in open oceans

...g over the past 50 years, the authors show a clear link to overfishing and highlight a surprising global pattern of open ocean hotspots - areas with predictable congregations of tuna, marlin, swordfish, and other ocean predators. Scientists say these hotspots - off the east coasts of the US, Australia, a...
