New drug blocks influenza, including bird flu virus

...a fragment of a larger human protein whose role in biology is to help things pass through membranes such as those that encapsulate cells. Although the peptide's precise mechanism for thwarting flu remains to be deciphered, it seems to work by blocking the virus' ability to latch onto a key cell surface mol...

'Failed' experiment yields a biocontrol agent that doesn't trigger antibiotic resistance

...erating Officer of the company. "Sal learned about biology and got experience with a start-up, and Dick and I got business expertise. It was a great partnership," Filutowicz says. In addition to federal funding from the National Science Foundation and the Department of Defense, the company has also attrac...

Fantastic Voyage: A new nanoscale view of the biological world

...ry (MIMS), which has applications in all fields of biology and biomedical research. "This method allows us to see what has never been seen before, and to measure what has never before been measured," Lechene says. "Imagine looking into a building, slice by slice. You can see not only that it contains apart...

A buffet for early human relatives

...ity of Utah distinguished professor of geology and biology ?says the study of the now-extinct, ape-like species known as Paranthropus robustus is important because it "shows that the variability in human diet has been 'in the family' for a very long time. It is this variability that allows modern humans to u...

New technique boosts size of proteins that can be analyzed

...a postdoctoral associate in chemistry and chemical biology and one of the paper's lead authors with fellow graduate student Xuemei Han. Jin said that the bottom-up approach is often used for larger scale studies of proteins because it can identify a large number of proteins from a sample, but it does not pro...

Tracing the formation of long-term memory

... Ronald Davis, professor of molecular and cellular biology at BCM. "This appears to be an authentic memory trace for long-term memory." Davis and his colleagues used spaced training to teach the flies to associate an odor with a mild electric shock. This method gives the fly a training trial, then a rest ...

Genetic surprise confirms neglected 70-year-old evolutionary hypothesis

...y. Masly and Orr, Masly's advisor and professor of biology at the University of Rochester, were talking one day when Orr suddenly recalled an off-hand comment from a scientist named Hermann J. Muller in a paper 60 years earlier. Muller speculated that perhaps since the sterility in the flies is so recessive-...

Neural networking nanotubes

...s the possibility of building an interface between biology and electronics. Kotov and colleagues at Oklahoma State University and the University of Texas Medical Branch have explored the properties of single-walled nanotubes (SWNTs) with a view to developing these materials as biologically compatible compo...

Study illuminates how the plague bacteria causes disease

...sed by bacterial pathogens to manipulate host cell biology is the mimicry of their own biochemical processes," Stebbins said. ...

Powerful genome ID method extended to humans

...apping method to humans, potentially giving cancer biology a faster and more cost-effective tool than traditional DNA sequencing. A student-led group from the laboratory of Michael Waterman, USC University Professor in molecular and computational biology, has developed an algorithm to handle the massive amo...

Wild gorillas carriers of a SIV virus close to the AIDS virus

... the prevalence, the geographical distribution and biology of SIV infections in these great apes, not forgetting the question of how the gorillas were contaminated. This last point remains a mystery,considered as rare....

Researchers in Montréal and the US create model of key immune-system component

...immune system. For the first time, using a systems biology approach, they have developed a model that facilit..." Dr. Stuart continues. "By combining classic cell biology with the newer approaches of proteomics, functional genomics and computational analysis, we have gen...

University of Iowa scientists explore function of 'junk DNA'

...dens understanding of a rapidly developing area of biology known as functional genomics and sheds more light ...ed is likely to be very important in many areas of biology and medicine." Over 450 microRNAs have been identified in the human genome. Learning how they are...

From hot springs to rice farms, scientists reveal new insights into the secret lives of archaea

A key antibody, IgG, links cells' capture and disposal of germs

...fft, associate professor of molecular and cellular biology in Harvard's Faculty of Arts and Sciences. "Our findings add yet another immunological task to the list of those handled by IgG." While just one of several broad classes of human antibodies, IgG is by far the most important -- so much so that pati...

Proteins may behave differently in natural environments

... assistant professor of biochemistry and molecular biology and co-director of the National Center for Macromolecular Imaging at BCM, and colleagues from BCM and The University of Texas Southwestern Medical Center in Dallas, found such dynamic behavior in a mutant form of a protein called GroEL, which chapero...

Taking 'chips' to the next level of gene hunting

...ays Jef Boeke, Ph.D., Sc.D, professor of molecular biology and genetics and director of the HiT (High Throughput Biology Center), who spearheaded both studies at the Institute of Basic Biomedical Sciences at Hopkins. "The other 97 percent also can contain disease-causing mutations and is often systematically...
