Dividing cells 'feel' their way out of warp
Every moment, millions of a body's cells flawlessly divvy up their genes and pinch perfectly in half to form two identical progeny for the replenishment of tissues and organs - even as they collide, get stuck, and squeeze through infinitesimally small spaces that distort their shapes. view more (2009-09-11)
Plants on steroids: Key missing link discovered
Researchers at the Carnegie Institution's Department of Plant Biology have discovered a key missing link in the so-called signaling pathway for plant steroid hormones (brassinosteroids). view more (2009-09-09)
Test developed at UQ diagnosed Australia's first swine flu victim
When the first cases of H1N1 Influenza (swine flu) were reported in Mexico in April, UQ researchers got to work developing a test to diagnose the virus. view more (2009-09-04)
Syracuse University research team discovers switch that causes the body to produce cancerous cells
A team of Syracuse University researchers discovered a second molecular switch within the Mixed Lineage Leukemia protein complex that they believe could be exploited to prevent the overproduction of abnormal cells that are found in several types of cancer, including leukemia. view more (2009-09-04)
Chemists reach from the molecular to the real world with creation of 3-D DNA crystals
New York University chemists have created three-dimensional DNA structures, a breakthrough bridging the molecular world to the world where we live. view more (2009-09-03)
Secrets of the 4 chambers revealed by reptile hearts
The first genetic link in the evolution of the heart from three-chambered to four-chambered has been found, illuminating part of the puzzle of how birds and mammals became warm-blooded. view more (2009-09-03)
Prodrug could help curb skin toxicity related to EGFR-inhibiting cancer drugs
There may be a way around the harsh skin toxicity associated with a widely used cancer drug, according to a study published online this week in Cancer Biology and Therapy by researchers from City of Hope and the Kimmel Cancer at Jefferson. view more (2009-09-02)

Dog's place and date of birth identified
Earlier studies of this field have shown that Eastern Asia is the place where the wolf was tamed to become the dog. view more (2009-09-01)
Chemotherapy resistance: Checkpoint protein provides armor against cancer drugs
Cell cycle checkpoints act like molecular tripwires for damaged cells, forcing them to pause and take stock. view more (2009-08-28)
Mice living in sandy hills quickly evolved lighter coloration
In a vivid illustration of natural selection at work, scientists at Harvard University have found that deer mice living in Nebraska's Sand Hills quickly evolved lighter coloration after glaciers deposited sand dunes atop what had been much darker soil. The work is described this week in the journal Science. view more (2009-08-28)
Newly Discovered Mechanism in Cell Division has Implications for Understanding Aberrant Chromosome's Role in Cancer, According to Penn Study
"A biologist, a physicist, and a nanotechnologist walk into a ..." sounds like the start of a joke. Instead, it was the start of a collaboration that has helped to decipher a critical, but so far largely unstudied, phase of how cells divide. view more (2009-08-18)
Newly found DNA catalysts cleave DNA with water molecule
Better tools for manipulating DNA in the laboratory may soon be possible with newly discovered deoxyribozymes (catalytic DNA) capable of cleaving single-stranded DNA, researchers at the University of Illinois say. view more (2009-08-17)
U of T scientists identify gene that has enabled water striders to glide across water
Water striders, the familiar semi-aquatic bugs gliding across the lake at the cottage, have a novel body form that allows them to walk on water. view more (2009-08-14)
Protein plays unexpected role protecting chromosome tips
A protein specialist that opens the genomic door for DNA repair and gene expression also turns out to be a multi-tasking workhorse that protects the tips of chromosomes and dabbles in a protein-destruction complex, a team lead by researchers at The University of Texas M. D. Anderson Cancer Center reports in the Aug. 13 edition of Molecular Cell. view more (2009-08-14)
Math model accurately mimics cell division in carbon-cycling bacterium
Scientists from the Department of Biological Sciences and the Virginia Bioinformatics Institute (VBI) at Virginia Tech have developed a quantitative, mathematical model of DNA replication and cell division for the bacterium Caulobacter crescentus. view more (2009-08-14)
Raising the alarm when DNA goes bad
Our genome is constantly under attack from things like UV light and toxins, which can damage or even break DNA strands and ultimately lead to cancer and other diseases. view more (2009-08-14)
Researchers identify potential new avenue to attack cancer
New insight into how human cells reproduce, published by cancer researchers at Michigan State University and the Van Andel Research Institute in Grand Rapids, could help scientists move closer to finding an "off switch" for cancer. view more (2009-08-13)
Launch of the first standard graphical notation for biology
Researchers at the European Molecular Biology Laboratory's European Bioinformatics Institute (EMBL-EBI) and their colleagues in 30 labs worldwide have released a new set of standards for graphically representing biological information - the biology equivalent of the circuit diagram in electronics. view more (2009-08-12)
