Protein synthesis can be controlled by light, opening way for new scientific, medical applications

...ins are the puzzle-pieces of life, involved in how organisms grow and flourish, but studying their complex biological processes in living systems has been extremely difficult. Now, a team of chemists and neurobiologists led by Timothy Dore at the University of Georgia and Erin M. Schuman at the California Inst...

Improved statistical tools reveal many linked loci

...yeast, their method can be applied to more complex organisms to search for even larger numbers of linked loci and to provide insights into the many interlocking pathways that make up the gene regulatory network.

Study: Well-known protein helps stem cells become secretory cells

...itical ability of certain glands and cell types in organisms from insects to humans. The researchers discovered that a protein called CrebA single-handedly controls the entire set of events leading to secretion in the fruit fly's salivary gland and epidermis, its skin-like outer layer. CrebA, or a closely re...

UNC plant researchers discover proteins interact to form hair-trigger protection against invaders

Proteomics brings researchers closer to understanding microbes that produce acid mine drainage

... "Genomes tell you about the genetic potential of organisms that are present in the environment, what organisms might be able to do," said Banfield, a scientist at Lawrence Berkeley National Laboratory. "But you ...

Researchers extend mouse lifespan by protecting against free radicals

...cals, then age-related diseases could be tamed and organisms ?and ultimately people ?may be able to live longer. Scientists have previously been able to extend the lifespan of mice in lab experiments by managing their diets and reducing their caloric intake. Another method relied on the restriction of a growt...

Scripps research scientists identify infertility molecule

... head on one end, are commonly found in biological organisms and are generally regarded as essential structural components of cells. For instance, bilayers of phospholipids are the primary component of cellular membranes, those essential barriers that define the boundaries of cells and keep the molecules insid...

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

...is incredible," said Genin. "It implies that these organisms have extremely sensitive depth sensors, the nature of which is yet unknown. That depth-keeping behavior has evolved in so many different species implies that this energetically demanding behavior provides significant, yet poorly understood benefits. ...

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

...nnate immune system, which is active in eukaryotic organisms as diverse as humans and fruit flies. Broadly speaking, the innate immune system works something like this. Certain cells have the ability to recognize foreign molecules such as components of membrane like LPS or other protein molecules unique to mic...

...s to come in, especially with respect to nocturnal organisms that do not have breeding congregations, where they don't come together en masse ever in their lives." He noted that numerous plants and animals in Asia and eastern North America share an evolutionary connection, suggesting some past geographic link...
