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)
Pitt researchers describe molecular '2-step' leading to protein clumps of Huntington's disease
In a paper published in the early online version of Nature Structural and Molecular Biology, researchers at the University of Pittsburgh School of Medicine deconstruct the first steps in an intricate molecular dance that might lead to the formation of pathogenic protein clumps in Huntington's disease, and possibly other movement-related... view more...

New breakthrough in global warming plant production
Researchers at the universities of Leicester and Oxford have made a discovery about plant growth which could potentially have an enormous impact on crop production as global warming increases. view more (2009-03-31)
New light microscope may help unlock some of cells' secrets
A microscopy technique pioneered with the help of Florida State University's National High Magnetic Field Laboratory has led to the development of a new light microscope capable of looking at proteins on a molecular level. view more (2006-08-17)
Molecular imaging holds promise for early intervention in common uterine cancer
A promising new molecular imaging technique may provide physicians and patients with a noninvasive way to learn more information about a type of cancer of the uterus lining called "endometrial carcinoma"-one of the most common malignant female tumors. view more (2009-10-01)
Scientists' cell discovery unearths evolutionary clues
The full family tree of the species known as social amoebas has been plotted for the first time - a breakthrough which will provide important clues to the evolution of life on earth. view more (2006-10-30)
Probability Controls The Molecule Of Life
Thanks to biophysicists, statistics has reached the most intimate aspect of life - regulation of genes' activity. Investigation on probabilistic aspects of molecular biology has been supported by the Russian Foundation for Basic Research and the INTAS Foundation. Regulation of genes' activity is one of the most important biological problems which... view more... (2004-05-24)
Temperature sensing by the circadian clock
In the September 1 issue of G&D, Dr. Michael Brunner and colleagues have uncovered the molecular mechanism whereby temperature affects circadian patterns in the fungus Neurospora. view more (2005-08-17)
University of Iowa scientists explore function of 'junk DNA'
University of Iowa scientists have made a discovery that broadens understanding of a rapidly developing area of biology known as functional genomics and sheds more light on the mysterious, so-called "junk DNA" that makes up the majority of the human genome. view more (2006-11-14)
MDC scientists show how hematopoietic stem cell development is regulated
During cell division, whether hematopoietic stem cells (HSCs) will develop into new stem cells (self-renewal) or differentiate into other blood cells depends on a chemical process called DNA methylation. view more (2009-10-07)
Atherosclerosis studied at the cellular level
A McMaster University study on atherosclerosis will be featured on the cover of the December issue of the high impact American Heart Association scientific journal, Arteriosclerosis, Thrombosis and Vascular Biology. view more (2005-12-02)
Molecular markers signal early metastases from ocular melanoma
Patients with melanoma of the eye are at risk for liver metastases, which are often not detected until they have turned into large, lethal tumors. view more (2006-09-14)
Trichoplax genome sequenced -- 'rosetta stone' for understanding evolution
Yale molecular and evolutionary biologists in collaboration with Department of Energy scientists produced the full genome sequence of Trichoplax, one of nature's most primitive multicellular organisms, providing a new insight into the evolution of all higher animals. view more (2008-09-04)
Researchers disrupt biochemical system involved in cancer, degenerative disease
Screening a chemical library of 200,000 compounds, researchers at UT Southwestern Medical Center have identified two new classes that can be used to study and possibly manipulate a cellular pathway involved in many types of cancer and degenerative diseases. view more (2009-02-02)
Movement of chromosome in nucleus visualized
The cell is understood to be highly organized, with specialized areas for different functions and molecular motors shuttling components around. view more (2006-04-18)
Failure to bridle inflammation spurs atherosclerosis
When a person develops a sore or a boil, it erupts, drawing to it immune system cells that fight the infection. Then it resolves and flattens into the skin, often leaving behind a mark or a scar. view more (2008-06-19)
Key protein molecule linked to diverse human chronic inflammatory diseases
Liwu Li, associate professor of biological sciences at Virginia Tech, has revealed a common connection between the cellular innate immunity network and human chronic inflammatory diseases, including atherosclerosis, Type 2 Diabetes, and neurodegenerative diseases. view more (2008-09-16)
Key protein regulating inflammation may prove relevant to controlling sepsis
Scientists at Singapore's Institute of Molecular and Cell Biology (IMCB), under the Agency for Science, Technology and Research (A*STAR), have identified the protein, WIP1, as the molecular "brake" that curbs severe inflammation in the body. view more (2009-05-15)
Newly discovered molecule promises better treatments for heart attacks, heart surgery
Scientists have discovered a compound that could lead to new treatments for heart attacks as well as methods to protect hearts during open heart surgery and other situations in which blood flow to the heart is interrupted. view more (2008-09-12)
Success comes at a cost, even for phages
As many a mother may tell you, expending the energy necessary to raise a clutch of kids can shave years off one's life. Trade-offs between reproductive success and survival have been demonstrated for a wide variety of organisms, in keeping with life history theory. view more (2006-06-13)
