Scientists synthesize memory in yeast cells
Harvard Medical School researchers have successfully synthesized a DNA-based memory loop in yeast cells, findings that mark a significant step forward in the emerging field of synthetic biology. view more (2007-09-17)
Double trouble: Cells with duplicate genomes can trigger tumors
Abnormal cell division that yields cells with an extra set of chromosomes can initiate the development of tumors in mice, researchers at Dana-Farber Cancer Institute have shown, validating a controversial theory about cancer causation put forth by a scientific visionary nearly 100 years ago. view more (2005-10-13)
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. Different genes operate in each cell type at different times, and this careful orchestration is what ultimately distinguishes a brain cell from a liver or skin cell. view more (2008-12-05)
Molecular 'GPS' helps researchers probe processes important in aging and disease
With all the hype about beneficial antioxidants in everything from face cream to cereal bars, you'd think their targets-oxygen radicals-must be up to no good. view more (2009-09-04)
Scientists reveal structure of gateways to gene control
Scientists at Penn State University will reveal in the 29 March 2007 issue of the journal Nature the first complete high-resolution map of important structures that control how genes are packaged and regulated throughout an entire genome. view more (2007-03-29)
Researchers identify protein-telomere interactions that could be key in treating cancer
A team of researchers from The Wistar Institute have shown that a large non-coding RNA in mammals and yeast plays a central role in helping maintain telomeres, the tips of chromosomes that contain important genetic information and help regulate cell division. view more (2009-09-01)
Largest synthetic gene ever built offers insights into anti-malarial drug resistance
Researchers at Georgetown University Medical Center say they are moving closer to understanding why the most lethal form of human malaria has become resistant to drug treatment in the past three decades. view more (2007-06-07)
MIT experts foresee sustainable ethanol production
As the search for alternative fuel sources intensifies, more and more attention has been focused on ethanol—a fuel many see as desirable because it burns cleanly and can be produced from plants. view more (2007-02-12)
Researchers examine mechanisms that help cancer cells proliferate
A process that limits the number of times a cell divides works much differently than had been thought, opening the door to potential new anticancer therapies, researchers at UT Southwestern Medical Center report in the Aug. 7 issue of the journal Cell. view more (2009-09-02)
CSHL researchers map changing epigenetic modifications that enable transposons to run amok
Much like cancer cells, plant cells grown for a long time outside of their normal milieu, in culture dishes, have highly unstable genomes. view more (2008-12-11)
Could skin cells become brain cells? (p 172)
Results of an experimental study in this week's issue of THE LANCET highlight how adult skin cells can be made into precursor nerve cells, with potential implications for the future treatment of neurodegenerative disorders such as Parkinson's disease. Ethical and practical considerations limit the availability of neural stem cells derived from... view more... (2004-07-07)
CSHL scientists discover new way in which ubiquitin modifies transcriptional machinery to regulate gene activity
During gene transcription - the process inside the nucleus of cells by which DNA, the genetic material, is copied into RNA - a large, ever-changing multiprotein complex is enlisted to assist the DNA-copying enzyme in its challenging job. view more (2008-12-19)
Work with power grids leads to cell biology discovery
Gene therapy, in which a working gene is inserted into a cell to replace a faulty or absent gene, is a promising experimental technique for the prevention and treatment of disease. view more (2008-03-18)
Self-digestion as a means of survival
In times of starvation, cells tighten their belts: they start to digest their own proteins and cellular organs. The process - known as autophagy - takes place in special organelles called autophagosomes. view more (2009-02-27)
Social habits of cells may hold key to fighting diseases
Scientists in Manchester are working to change the social habits of living cells - an innovation that could bring about cleaner and greener fuel and help fight diseases such as cancer and diabetes. view more (2007-08-27)
Dartmouth, GlycoFi researchers make leap in protein bioengineering
Investigators at Dartmouth's Thayer School of Engineering, the Dartmouth-Hitchcock Medical Center, and the biotechnology firm GlycoFi, Inc., report a breakthrough in using yeast to produce antibodies with human sugar structures. view more (2006-01-23)
Researchers discover architecture for fundamental processes of life
A team of Canadian researchers has completed a massive survey of the network of protein complexes that orchestrate the fundamental processes of life. view more (2008-05-14)
Mad-cow culprit maintains stem cells
What do mad cow disease and stem cell research have in common? Whitehead Institute scientists have found that the same protein that causes neurodegenerative conditions such as bovine spongiform encephalopathy (mad cow disease) is also important for helping certain adult stem cells maintain themselves. view more (2006-01-31)
Researchers develop new method to help find deadly malaria parasite's Achilles heel
Researchers at UCSD have discovered that the single-cell parasite responsible for an estimated 1 million deaths per year worldwide from malaria has protein "wiring" that differs markedly from the cellular circuitry of other higher organisms. view more (2005-11-03)
Case researcher in RNA biology makes waves by challenging current thinking
In the January 18th issue of Molecular Cell, Case Western Reserve University School of Medicine researcher Kristian E. Baker, Ph.D. challenges molecular biology's established body of evidence and widely-accepted model for nonsense-mediated messenger ribonucleic acid (mRNA) decay. view more (2008-01-21)
