Enzyme synergy shown to perpetuate sleeping sickness
The pathogenesis of the parasite African trypanosome (T. brucei) has been linked to a key protein switch, detailed in a new study by researchers at the University of Iowa and the Veterans Affairs Medical Center of Iowa City, led by Dr. John Donelson. view more (2007-10-19)
Can pathological techniques help identify primary colorectal signet ring cell carcinoma?
Primary colorectal signet ring cell carcinoma is a rare but distinctive malignancy of the large bowel. More than 96% of signet ring cell carcinomas arise in the stomach, with the rest arising from other primary organs. view more (2008-05-21)
'Invisibility cloak' could protect against earthquakes
Research at the University of Liverpool has shown it is possible to develop an 'invisibility cloak' to protect buildings from earthquakes. view more (2009-07-21)
MIT researchers fired up about battery alternative
Just about everything that runs on batteries - flashlights, cell phones, electric cars, missile-guidance systems - would be improved with a better energy supply. But traditional batteries haven't progressed far beyond the basic design developed by Alessandro Volta in the 19th century. view more (2006-02-08)
Blocked gene may provide new treatment for allergies
Allergic reactions like hay fever can recur over long periods since the allergenic mast cells survive and revive. A team of Uppsala scientists have now identified the mast cell's survival gene, and by blocking this gene, they can inhibit allergic reactions, opening new avenues for treatment. These findings have been published in Monday's issue... view more... (2001-12-05)
Alberta's hidden valleys offer both resources and danger
Alberta is crisscrossed with hidden glacial valleys that hold both resource treasures and potential danger. University of Alberta researcher Doug Schmitt discovered a 300 metre deep, valley hidden beneath the surface of the ground near the community of Rainbow Lake in northwestern Alberta. view more (2009-11-13)
Popcorn-ball design doubles efficiency of dye-sensitized solar cells
A new approach is able to create a dramatic improvement in cheap solar cells now being developed in laboratories. view more (2008-04-11)
It will be possible to predict earthquakes from space
The scientists of the Department of Physics, Moscow State University, have proposed to predict earthquakes by measuring polarization of the solar light that is reflected from the surface of the Earth. The small and cheap equipment, which the scientists have designed, can be placed on meteorological satellites. Polarization of solar light at... view more... (2001-01-17)
The Nobel Prize in Chemistry 2003
The two American scientists Peter Agre, 54, and Roderick MacKinnon, 47, will receive this years Nobel Prize in Chemistry "for discoveries concerning channels in cell membranes". view more (2003-10-09)
Nicotine rush hinges on sugar in neurons
When nicotine binds to a neuron, how does the cell know to send the signal that announces a smoker's high" view more (2007-07-23)
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)
HIV pays a price for invisibility
Mutations that help HIV hide from the immune system undermine the virus's ability to replicate, show an international team of researchers in the April 13 issue of the Journal of Experimental Medicine. view more (2009-04-13)
New rotors could help develop nanoscale generators
In collaboration with the Chinese Academy of Sciences in Beijing, scientists have investigated the rotation of molecules on a fixed surface to understand how they may help in the development of future rotor-based machinery at nanoscale level. view more (2009-05-28)
Antibody Extends Life of Mice with Breast Cancer
A monoclonal antibody developed by researchers at the University at Buffalo has been shown to extend significantly the survival of mice with human breast-cancer tumors and to inhibit the cancer's spread to the lungs in the animals by more than 50 percent. view more (2006-12-12)
MIT works toward engineered blood vessels
MIT scientists have found a way to induce cells to form parallel tube-like structures that could one day serve as tiny engineered blood vessels. view more (2007-12-18)

North Sea efficient sink for carbon dioxide
The measured annual increase in the concentration of carbon dioxide (CO2) in the atmosphere is only 60 percent of the annual emissions from fossil fuels. view more (2005-10-11)
Yale scientists create artificial 'cells' that boost the immune response to cancer
Using artificial cell-like particles, Yale biomedical engineers have devised a rapid and efficient way to produce a 45-fold enhancement of T cell activation and expansion, an immune response important for a patient's ability to fight cancer and infectious diseases, according to an advance on line report in Molecular Therapy. view more (2008-02-27)
New role for sugars: Research shows connections between sugar modifications in cells and cancer
In a ground-breaking study published in the top journal, Cell, Dr. James Dennis, senior investigator at the Samuel Lunenfeld Research Institute at Mount Sinai Hospital, has discovered a new role for sugars on proteins. view more (2007-04-06)
A step forward in virology
The vaccinia virus has a problem: it is a giant among viruses and needs a special strategy in order to infiltrate a cell and reproduce. view more (2008-04-25)
