Can engineered immune cells stop AIDS?

...ds great promise as a way to harness the insidious power of viruses such as human immunodeficiency syndrome (HIV). But scientists have yet to solve a vexing problem: developing an efficient transport system that is capable of delivering therapeutic payloads to specific cells. As challenging as the proble...

Speeding 'fingertip' discovery -- 20 years of protein info in 1 place

...ylation sites in any protein of interest. “The power of this technique is not just in the numbers,?says Pandey. “Rather, we’ve found what you might call new information about old proteins, and we hope the new data will help researchers study their favorite proteins in greater depth. After all, there’s ...

Billions of dollars saved in US by polio vaccination

...olio said, "This study documents the extraordinary power of vaccines not only as highly effective tools to prevent disease, disability, and death, but to provide enormous economic savings to society." Although the last case of paralytic polio from wild poliovirus occurred in the U.S. in 1979, polioviru...

Scientists map air pollution using corn grown in US fields

...oided pollution point sources such as highways and power plants to allow for mapping of regional patterns across different states. Back in the laboratory, the scientists dried samples of corn leaves and husks, then converted them to graphite using a series of chemical reactions. The graphite then was analy...

Lower carbon dioxide emissions from coal-fueled power plants possible with technology development

Study finds mercury prevalent in many western fish

...nmade sources, the researchers say, including coal power plants from as far away as China, the burning of heavy oils and other fossil fuels, and even forest fires. In the survey, the researchers did find 13 fish from eight different sites that had very high mercury concentrations ?levels of 1.0 microgra...

MIT bioengineer advances survival, promise of adult stem cells

...F and degrades it, and the growth factor loses its power to influence cell behavior. This has made EGF notoriously difficult to develop as a clinical product for wound healing. To control this, the researchers decided to tether EGF to a scaffold, preventing the stem cells from eating it up and allowing ...

Plant studies reveal how, where seeds store iron

...in. "This project is a wonderful example of the power of using new combinations of tools--in this case, genetics and high-resolution 3-dimensional X-ray fluorescence imaging--to understand gene function," said Jane Silverthorne, a program director in NSF's Division of Biological Infrastructure, which fu...

Proteins may predict lung transplant rejection

...enting the conference. The researchers used the power of computers and new, sophisticated methods of analysis to find the proteins that form a "biosignature" or "biomarker" of organ rejection from among the thousands of proteins that exist in the lung. Disease disturbs protein function Lung tran...

One-of-a-kind imaging probe reveals secrets useful for drug discovery

...e this particular method unique is not the extreme power of the magnet, which at 600 megahertz is fairly standard, but the extreme sensitivity of the probe - the component that is inserted into the magnet to obtain chemical information from the samples. Developed by scientists at the National High Magneti...

UCSF study will test new vaginal microbicide for herpes and HIV

...icance of the gel is that it potentially gives the power back to the woman to protect herself against infection," said Anna-Barbara Moscicki, MD, professor of pediatrics at UCSF and lead investigator for the study. The gel is not a contraceptive, but a microbicide. Microbicidal gels or creams are inser...

Stem cells engage in dialogue with the cells that regulate their futures

... in the neighborhood. It may very well be that the power of cancer cells to spread comes from this natural ability of stem cells to make a home when in a hospitable environment. We all need a home, and stem cells with their strong survival instinct are active homebuilders." ...

Science researchers genetically transform immune cells into tumor fighters

...ork marks an important next step in harnessing the power of our immune systems to fight cancer. The publication of this paper should help highlight the significant work to a broad spectrum of people, including patients, clinicians and those involved in basic research," said Stephen Simpson, Science's senio...

Gold nanoparticles prove to be hot stuff

...often used in optical traps. Unless very low laser power is used, the heat could damage the molecules under study. Thus, gold beads would not be useful for temperature-sensitive experiments or applying force to molecules. But the heating effect could be useful in raising local temperatures in certain exper...
