ORNL, UC Berkeley unravel real-world clues to Earth's mysteries

...searchers in their quest to understand the complex biological relationships and how these inner workings might apply on a grander scale. In a paper to appear today on Science Online, researchers from the Department of Energy's Oak Ridge National Laboratory and the University of California Berkeley describe a b...

Arthritis: What Wnt wrong?

...research associate. Nakamura has been studying the biological activities and signaling pathway of a Wnt-related gene that causes severe joint degenerative disease in humans. "More specific analyses such as gain-of-function and loss-of-function study of Wnt-7b will give us a clue which Wnt-7b would be an import...

For instance, bilayers of phospholipids are the primary component of cellular membranes, those essential barriers that define the boundaries of cells and keep the molec...

Researchers use 3-D imaging system to unveil swimming behavior of microscopic plankton

...e zooplankton patchiness is a central objective in biological oceanography." Countless numbers of the minute, nearly transparent zooplankton are found under the surface of each square meter of the world's oceans. These animals play a key role in the marine food web as a crucial link between primary producers a...

First production of human monoclonal antibodies in chicken eggs published in Nature Biotechnology

...duced by this method had very similar physical and biological characteristics to those produced in CHO cells, including nearly identical binding curves, similar affinities, and an equal ability to be internalized by antigen on prostate cancer cells. At the same time, chicken-produced antibodies lacked the sugar...

Scripps research scientists solve structure of a critical innate immune system protein

... with sugars (glycans), and fall into the class of biological molecules known as "glycoproteins." "Amazingly there is still this prevalent idea [many scientists have] that glycoproteins don't crystallize," says Wilson. Crystallization of a protein is a crucial initial step in solving its structure via x-ray cr...

Green catalyst destroys pesticides and munitions toxins, finds Carnegie Mellon University

...eady have shown promise in killing a simulant of a biological warfare agent (anthrax), reducing fuel pollutants, treating pulp and paper processing byproducts, and detoxifying pesticides. A major goal is to develop Fe-TAMLs as a safe, cost-effective means of global water decontamination. Collins and other mem...

Dan Luo, Cornell assistant professor of biological and environmental engineering in whose lab the DNA structures were made, suggests that drugs could be encapsulated in buckyballs to be carried into cells, where natural enzymes would break down the DNA, releasing the drug. They might also be used as ...

Johns Hopkins University is seeking partners who would like to license this patent-pending methodology. Inquiries may be directed to Deborah Alper at the Johns Hopki...

New tool reveals secrets of migrating cells

...ing to change literally forever the way that we do biological science," said Witt, a developmental immunologist. "In the past, we'd take organs out, smush them up and basically do biochemistry in test tubes, or watch their behavior in a single layer of cells. It's an imaging revolution to be able to go into the...
