Family trees of ancient bacteria reveal evolutionary moves
A geomicrobiologist at Washington University in St. Louis has proposed that evolution is the primary driving force in the early Earth's development rather than physical processes, such as plate tectonics. Carrine Blank, Ph.D., Washington University assistant professor of geomicrobiology in the Department of Earth & Planetary Sciences in Arts & Sciences, studying Cyanobacteria ?bac...Revolutionary nanotechnology illuminates brain cells at work
Until now it has been impossible to accurately measure the levels of important chemicals in living brain cells in real time and at the level of a single cell. Scientists at the Carnegie Institution's Department of Plant Biology and Stanford University are the first to overcome this obstacle by successfully applying genetic nanotechnology using molecular sensors to view changes in brain chemical l...The evolutionary triumph of flower power
Enjoying spring flowers? Flowers have flourished ?their beauty evolving over time ?simply because we like them, says Terry McGuire, associate professor of genetics at Rutgers and co-author of a paper that examines for the first time the whys and wherefores of flowering plants in an evolutionary context. While flowers originally came on the scene to attract potential pollinators like bugs...Multi-species genome comparison sheds new light on evolutionary processes, cancer mutations
An international team that includes researchers from the National Human Genome Research Institute (NHGRI), part of the National Institutes of Health (NIH), has discovered that mammalian chromosomes have evolved by breaking at specific sites rather than randomly as long thought ?and that many of the breakage hotspots are also involved in human cancer. In a study published in the July 22 iss...The first laugh: New study posits evolutionary origins of two distinct types of laughter
In an important new study from the forthcoming Quarterly Review of Biology, biologists from Binghamton University explore the evolution of two distinct types of laughter ?laughter which is stimulus-driven and laughter which is self-generated and strategic. "Laughter that occurs during everyday social interaction in response to banal comments and humorless conversation is now being studied...EraGens Revolutionary Genomic-Based Technologies
MADISON, Wis. - EraGen Biosciences of Madison, WI is a pioneering biotechnology company that designs, develops and commercializes genomic-based products and novel nucleic acid technologies. With start-up funding in 1999 from the pharmaceutical firm Novartis and private investors, the company has grown to 32 employees, includin...Evolutionary developmental biology

Babies will put almost anything in their mouths. But as children get older, they become more selective about what they eat,// particularly if they have not tried it before. Green vegetables and meat can be particularly troublesome.But scientists say thousands of years ago toxins in plants could have harmed children, and meat carried a high risk of food poisoning.So it makes sense that...Revolutionary Simple Pregnancy Blood Test Can Save Both Mother And Child
Pre-eclampsia is a disease that causes high blood pressure in 20th week// of Pregnancy and is a major cause of death of mother and infant in the world. Now a simple test that measures HLA-G levels in blood can predict women who are likely to develop the problem. Researchers in Canada may have discovered this simple blood test. "We're really excited about this finding," said Clifford L...Revolutionary Pill Cuts Risk of Breast Cancer
The next five to ten years may see the development of a new contraceptive pill that reduces breast cancer risk as well as heart disease. It also has the added benefit of eliminating periods. // The Combined Pill, currently available to women around the world is a combination of estrogen and progesterone. Estrogen however increases the risk of breast cancer and heart problems such as...A Revolutionary New Treatment For Cancer Available In Australia
A radical new cancer treatment might cause a cancer revolution is available to all Australians. This new treatment targets tumors with radioactive microspheres.// Pioneered by an Australian, this radiation therapy is most often used for bowel cancer patients who develop secondary liver cancer but is expected to be extended to other cancers. The treatment was previously available only...New Revolutionary Drug Could Stop the Spread of HIV
A new revolutionary drug manufactured by a US biotechnology company could block the spread of HIV, say scientists after finding its benefits in a small-scale human trial. // Human Immunodeficiency Virus (HIV) steadily weakens the body's immune system until it can no longer fight off infections such as pneumonia, diarrhea, tumours and other illnesses. Unable to fight back,...Mild Asthma, a Revolutionary Therapy from Italian Research
