Bacteria and nanofilters - the future of clean water technology
Bacteria often get bad press, with those found in water often linked to illness and disease. But researchers at The University of Nottingham are using these tiny organisms alongside the very latest membrane filtration techniques to improve and refine water cleaning technology. view more (2008-02-25)
Bacterial toxin closes gate on immune response, Penn researchers discover
Researchers at the University of Pennsylvania School of Medicine have demonstrated that a bacterial toxin from the common bacterium Staphylococcus aureus shuts down the control mechanism of the tunnel, called an ion channel, in immune cell membranes. view more (2008-02-14)
Singapore nanotechnology combats fatal brain infections
Doctors may get a new arsenal for meningitis treatment and the war on drug-resistant bacteria and fungal infections with novel peptide nanoparticles developed by scientists at the Institute of Bioengineering and Nanotechnology (IBN) of Singapore and reported in Nature Nanotechnology. view more (2009-06-29)
Super-thin Filter, 50 Atoms Thick, Sorts Individual Molecules
A newly designed porous membrane, so thin it's invisible edge-on, may revolutionize the way doctors and scientists manipulate objects as small as a molecule. view more (2007-02-15)
Scientists fool bacteria into killing themselves to survive
Like firemen fighting fire with fire, researchers at the University of Illinois and the University of Massachusetts at Amherst have found a way to fool a bacteria's evolutionary machinery into programming its own death. view more (2008-12-17)
Findings reveal how dengue virus matures, becomes infectious
Biologists at Purdue University have determined why dengue virus particles undergo structural changes as they mature in host cells and how the changes are critical for enabling the virus to infect new host cells. view more (2008-03-28)
£4 Million for New Centres for Structural Biology
The Biotechnology and Biological Sciences Research Council (BBSRC) today announces its intention to fund four more UK Centres for Structural Biology. view more (1999-02-01)
Buckyballs could keep water systems flowing
Microscopic particles of carbon known as buckyballs may be able to keep the nation's water pipes clear in the same way clot-busting drugs prevent arteries from clogging up. view more (2009-03-05)
The lively little girl is a miracle for everyone
When the bag of waters burst in the 20th week of pregnancy, the unborn child only had a very slim chance of surviving birth. The high risk of infection was not the only risk to Miriam's life. view more (2007-10-29)
New membrane strips carbon dioxide from natural gas faster and better
A modified plastic material greatly improves the ability to separate global warming-linked carbon dioxide from natural gas as the gas is prepared for use, according to engineers at The University of Texas at Austin who have analyzed the new plastic's performance. view more (2007-10-12)
Why could prednisolone suppress the hepatic ischemia-reperfusion injury?
Hepatic ischemia-reperfusion injury is a serious complication but unavoidable problem in liver surgery including liver transplantation and hepatic resection. view more (2008-10-08)
New clues for treatment of disease that causes accelerated aging
There is renewed hope for treatment of a rare genetic condition that causes rapidly accelerated aging and leads to an average life expectancy of 13 years. view more (2007-05-03)
Animal testing alternative has ticks trembling at the knees
The thousands of test animals currently required to evaluate new pesticides could be replaced by tricking ticks into setting up home on a faux cow hide. view more (2006-11-06)
What Makes The Scorpion`S Sting Deadly Poisonous?
Even the scorpion`s exterior warns that this is a dangerous animal. And it proves to be true, as nothing good comes out when small animals and even human beings meet with this arthropod species: its sting causes a sharp pain, some tropical scorpion`s sting is often fatal for the victim. The scientists from the Moscow Institute for Organoelement... view more... (2002-03-15)
Proteomics Study Yields Clues As To How Tuberculosis Might Be Thwarting The Immune System
A link between the immune system and the self-cleaning system by which biological cells rid themselves of obsolete or toxic parts may one day yield new weapons in the fight against tuberculosis and other deadly infectious diseases. view more (2008-11-06)
Sleeping sickness parasite shows how cells divide their insides
Graham Warren, professor of cell biology, and his colleagues at Yale study Trypanosoma brucei, the parasite that causes Sleeping Sickness. view more (2005-11-08)
Zooming in on the protein-conducting channel
Researchers have gained the most detailed view yet of the heart of the translocon, a channel through which newly constructed proteins are inserted into the cell membrane. view more (2005-11-17)
Nixing immaturity in red blood cells
A process of self-digestion called autophagy prompts the maturation of red blood cells. Without a protein called Nix, the cells would not effectively rid themselves of organelles called mitochondria and consequently become short-lived, leading to anemia, said researchers at Baylor College of Medicine in Houston in a report that appears online... view more...

Medical Breakthrough in Engineering and Monitoring 3-D Tissue
Researchers at Oxford University's Department of Engineering Science have recently made great lengths in both engineering and monitoring 3-dimensional tissue. Engineering tissue involves the seeding of appropriate cells into a scaffold to form a bio-construct or matrix. The Oxford team has improved this process by developing a new kind of nutrient... view more... (2003-10-13)
Engineered eggshells to help make hydrogen fuel
Engineers at Ohio State University have found a way to turn discarded chicken eggshells into an alternative energy resource. The patented process uses eggshells to soak up carbon dioxide from a reaction that produces hydrogen fuel. It also includes a unique method for peeling the collagen-containing membrane from the inside of the shells, so that... view more... (2007-09-27)
