Genetic Study of House Dust Mites Demonstrates Reversible Evolution
March 8, 2013 — In evolutionary biology, Dollo's law states that evolution is unidirectional and irreversible. But this "law" is not universally accepted and is the topic of heated debate among biologists. Now a ... > full story -
Scientists Find More Precise Way to Turn Off Genes, a Major Goal of Treatments That Target Cancer
March 7, 2013 — Scientists have found a more precise way to turn off genes, a finding that will speed research discoveries and biotech advances and may eventually prove useful in reprogramming cells to regenerate ... > full story -
Stocking Florida Bass in Texas Reservoirs May Alter Stream Systems Connected to Stocked Reservoirs
March 7, 2013 — A genetic analysis by biologists suggests that the stocking of Florida bass in Texas reservoirs impacts bass populations far beyond the actual stocking ... > full story -
Scientists Catch Evolving Germs and Cancer Cells Early
March 7, 2013 — Scientists have developed a novel technique to precisely monitor and study the evolution of micro-organisms such as viruses and bacteria. This is an extremely important capability as it allows ... > full story -
'Gateway' in Nucleus Has Second Important Job No One Noticed Before
March 7, 2013 — Medical researchers have discovered that the "gateway" known to control the movement of molecules in and out of a cell's nucleus appears to play another critically important role -- one no one had ... > full story -
Pushing the Boundaries: Study Provides Key Insight Into How Cells Fuse
March 7, 2013 — Researchers have established a high-efficiency cell-cell fusion system, providing a new model to study how fusion works. The scientists showed that fusion between two cells is not equal and mutual as ... > full story -
Protein Lost in Tumors Blocks Normal Cells from Being Reprogrammed Into Stem Cells
March 7, 2013 — Researchers have discovered that a particular protein prevents normal cells from being reprogrammed into cells that resemble stem cells, providing new insight into how they may lose their plasticity ... > full story -
Key Developmental Mechanism in Plants Explained for First Time
March 7, 2013 — In simple animals like the fruit fly and more recently in plants and mammals, scientists have been able to identify some of the principal players in the developmental symphony. Scientists have now ... > full story -
Cancer-Promoting Protein Is Found to Also Suppress Cell Growth
March 7, 2013 — The cancer-causing oncogene SRSF1, first discovered through its role in splicing, is now shown also to activate cell-growth arrest, or senescence. In states of ribosomal stress or overexpression of ... > full story -
Dual Systems Key to Keeping Chromosomes Intact
March 7, 2013 — Scientists have discovered how two different structural apparatuses collaborate to protect repetitive DNA when it is at its most vulnerable -- while it is being unzipped for ... > full story
