| A 'jumping gene's' preferred targets may influence genome evolution Posted: 06 Sep 2011 01:16 PM PDT Our genetic blueprint contains numerous entities known as transposons, which have the ability to move from place to place on the chromosomes within a cell. An astounding 50 percent of human DNA comprises both active transposon elements and the decaying remains of former transposons. Every time a plant or animal cell prepares to divide, the chromosome regions richest in transposon-derived sequences are among the last to duplicate. New research provides potential insight into both these enigmas.  |
| New cellular surprise may help scientists better understand human mitochondrial diseases Posted: 06 Sep 2011 12:25 PM PDT A surprising new discovery regarding the division of tiny "power plants" within cells known as mitochondria has implications for better understanding a wide variety of human diseases and conditions due to mitochondrial defects.  |
| Scientists pinpoint shape-shifting mechanism critical to protein signaling Posted: 06 Sep 2011 12:24 PM PDT Scientists have shown that changes in a protein's structure can change its signaling function and they have pinpointed the precise regions where those changes take place. The new findings could help provide a much clearer picture of potential drugs that would be both effective and highly specific in their biological actions.  |
| Recycling fat might help worms live longer Posted: 06 Sep 2011 09:12 AM PDT Scientists found that two cellular processes -- lipid metabolism and autophagy -- work together to influence lifespan in C. elegans worms. Autophagy, a mechanism cells use to recycle their own contents, has been implicated in many human diseases, including cancer. This study provides a more detailed understanding of the roles autophagy and lipid metabolism play in aging.  |
| Posted: 06 Sep 2011 05:54 AM PDT New research has uncovered the mechanism that allows cells to switch from sender to receiver mode, inhibiting their own signals while receiving information from other cells. With this knowledge, researchers may be able to develop new cancer drugs that specifically target these transactions, potentially stopping cancer's uncontrollable proliferation.  |
| Growing meat in the lab: Scientists initiate action plan to advance cultured meat Posted: 06 Sep 2011 05:51 AM PDT An international group of scientists recently took a step closer to their goal to produce cultured meat, during a workshop in Sweden. Many technology components are now coming into place in order to realize the concept of cultured meat. This includes a cell source that is possible to use, several alternative processes to turn these cells into muscle cells for meat, and nutrients free of animal components which can be produced from sunlight and carbon dioxide.  |
