Researchers map changing epigenetic modifications that enable transposons to run amok

Cold Spring Harbor, N.Y. – Much like cancer cells, plant cells grown for a long time outside of their normal milieu, in culture dishes, have highly unstable genomes.

Computation and genomics data drive bacterial research into new golden age

A potent combination of powerful new analysis methods and abundant data from genomics projects is carrying microbiology forward into a new era.

Model unravels rules that govern how genes are switched on and off

For years, scientists have struggled to decipher the genetic instruction book that details where and when the 20,000 genes in a human cell will be turned on or off.

Metabolic reactions: Less is more in single-celled organisms

A Northwestern University study has found a surprising similarity among four quite different organisms.

Reactions to HPV vaccine Gardasil rare

Research by Australian scientists has found that adverse reactions to the HPV vaccine Gardasil are rare and most schoolgirls are able to tolerate subsequent doses.

New technique provides closer look at DNA and mRNA

In a study in the advance online edition of Nature Structural and Molecular Biology, researchers from Albert Einstein College of Medicine describe a technique for looking more precisely at a fundamental step of a cell's life - a gene, DNA, being read into a message, mRNA.

Yeast provides new insight into cholesterol-lowering drugs

Having discovered how a lowly, single-celled fungus regulates its version of cholesterol, Johns Hopkins researchers are gaining new insight about the target and action of cholesterol-lowering drugs taken daily by millions of people to stave off heart attacks and strokes.

Protein-misfolding accelerates yeast evolution

Under stress, yeast cells can unleash a remarkable mechanism based on protein-misfolding that gives them new characteristics without requiring genetic mutations.

Researchers provide new evidence that aging can be slowed

New evidence may explain why it is that we lose not only our youthful looks, but also our youthful pattern of gene activity with age.

Researchers provide new insight into adaptive ability of cells

The Stowers Institute's Rong Li Lab has published findings that shed light on the ability of cells to adapt to disruptions to their basic division machineries - findings that may help explain how cancer cells elude the body's natural defense mechanisms or chemotherapy treatment.

Researchers identify a potentially universal mechanism of aging

Like our current financial crisis, the aging process might also be a product excessive deregulation.

Dieters could have a harder time fighting flu

In a study published in the November issue of the Journal of Nutrition, Gardner showed that mice with a calorie-restricted diet were more likely to die during the first few days of infection than mice with a normal diet. Caloric restriction is the practice of reducing the intake of calories to 40 percent of a normal diet, while maintaining adequate vitamins and minerals.

Scientists shed light on how DNA is unwound so that its code can be read

Researchers at The Scripps Research Institute have figured out how a macromolecular machine is able to unwind the long and twisted tangles of DNA within a cell's nucleus so that genetic information can be "read" and used to direct the synthesis of proteins, which have many specific functions in the body.

Prion switching in response to environmental stress

If you have had a hard day at work, you may change your eating habits, perhaps favoring comfort food, but you don't suddenly develop the ability to eat the plate and cutlery.

Scientists find cells reorganize shape to fit situation

Flip open any biology textbook and you're bound to see a complicated diagram of the inner workings of a cell, with its internal scaffolding, the cytoskeleton, and how it maintains a cell's shape.

FDA strengthens safety of Sucraid (sacrosidase) oral solution

The U.S. Food and Drug Administration today issued an expedited approval of a supplemental application that allows for changes in the manufacturing of Sucraid (sacrosidase) Oral Solution.

New gene-silencing pathway found in plants

Biologists at Washington University in St. Louis have made major headway in explaining a mechanism by which plant cells silence potentially harmful genes.

New clue for cellular damage in Huntington's disease

"Huntington's disease presents an ideal vantage point to study neurodegenerative disease, because we know the misfolded protein that's responsible," says Martin Duennwald, formerly a postdoctoral researcher in the lab of Whitehead Member Susan Lindquist.
