Synthetic production of potential pharmaceuticals dramatically simplified by Scripps research team
Chemists are currently able to synthetically produce almost any compound, but they must typically resort to expensive, complex processes that can require dozens of individual steps. view more (2007-03-22)
Atomic structure of the mammalian 'fatty acid factory' determined
Mammalian fatty acid synthase is one of the most complex molecular synthetic machines in human cells. It is also a promising target for the development of anti-cancer and anti-obesity drugs and the treatment of metabolic disorders. view more (2008-09-05)
Boston University scientists first to see RNA network in live bacterial cells
Scientists who study RNA have faced a formidable roadblock: trying to examine RNA's movements in a living cell when they can't see the RNA. Now, a new technology has given scientists the first look ever at RNA in a live bacteria cell-a sight that could offer new information about how the molecule moves and works. view more (2009-10-23)
"Nanosculpture" Could Enable New Types of Heat Pumps and Energy Converters
A new technique for growing single-crystal nanorods and controlling their shape using biomolecules could enable the development of smaller, more powerful heat pumps and devices that harvest electricity from heat. view more (2008-07-21)
Stress causes parodontis
Under stress, major proteins get actively destroyed in the parodentium. According to biologists' data, chronical stress inhibits the osseous tissue maturing process and intensifies decomposition of collagen protein and proteoglycans with the animals non-resistant to stress. Stress intensifies hydrolysis of proteins, which make the basis of the... view more... (2003-09-26)
Discovery of metabolic pathway for parasite could lead to new controls for diseases
Toxoplasma gondii is one nasty bug. A microscopic parasite, it lives in the intestinal tract of cats but can be carried by most warm-blooded animals. In humans, it can harm or even kill a developing fetus, and it can as well sicken those with compromised immune systems, such as AIDS patients. view more (2006-08-15)
Making bacteria make useful proteins
By adapting a single protein on the surface of the bacterium Caulobacter crescentus, researchers at the University of British Columbia have turned it into a protein production factory, making useful proteins that can act as vaccines and drugs. view more (2009-09-08)
Oxford Improves Production Method for Interfering RNA
Researchers at Oxford University's Department of Biochemistry have developed methods for making RNA duplexes and single-stranded RNAs of desired length and sequence. This exciting technology is most applicable to commercial RNA providers and companies with large in-house requirements for RNA molecules as it will greatly increase... view more... (2003-04-29)
Researchers discover how antibiotic inhibits bacterial growth
Researchers at the University of Illinois at Chicago, in collaboration with research teams from Pharmacia & Upjohn and Pfizer, have discovered precisely how the antibiotic linezolid inhibits bacterial growth. view more (2007-05-11)
Genetic breakthrough supercharges immunity to flu and other viruses
Researchers at McGill University have discovered a way to boost an organism's natural anti-virus defences, effectively making its cells immune to influenza and other viruses. view more (2008-02-14)
Amyloid beta protein gets bum rap
While too much amyloid beta protein in the brain is linked to the development of Alzheimer's disease, not enough of the protein in healthy brains can cause learning problems and forgetfulness, Saint Louis University scientists have found. view more (2009-11-10)
Protein binds whenever it can
Dutch cancer researcher Joost Martens has discovered that the protein p300, which plays an important role in the correct transcription of DNA to RNA, can bind to DNA at several sites. The protein can also occupy a position in various complexes, each with its own protein composition. This knowledge is important for gaining a better understanding of... view more... (2003-06-24)
Stress signals link pre-existing sickness with susceptibility to bacterial infection
Mitochondrial diseases disrupt the power generating machinery within cells and increase a person's susceptibility to bacterial infection, particularly in the lungs or respiratory tract. view more (2009-07-28)
Titania nanoparticles could lead to improved sensors and solar energy
Nanostructured titania (TiO2) has been extensively studied as a very promising material for applications in sensors, photocatalysis, solar energy conversion and optical coatings. view more (2005-12-06)
Scientists uncover secrets of potential bioterror virus
Researchers at the University of Texas Medical Branch at Galveston have discovered a key tactic that the Rift Valley fever virus uses to disarm the defenses of infected cells. view more (2009-02-17)
Global Society to Host Oils & Fats World Conference
The ISF World Congress is a one-stop forum drawing speakers from over 30 countries and representing the production, supply, markets and applications of fish oil, palm oil, oilseeds and dairy fats, amongst others. Topics covering the whole spectrum of related issues and applications - including food processing, legislation, nutrition, healthcare,... view more... (1999-09-30)
The dance of crystal structures
The word "crystal" is a technical term; iron and steel, for example, are crystals whereas glass is not. In fact, "crystal" means materials of a crystalline structure. view more (2004-11-10)
Keeping in good shape in old age is harder for women, study finds
Women aged 65-plus find it harder than men of the same age to preserve muscle - which probably impacts on their ability to stay as strong and fit, according to new research. view more (2008-03-26)
Toxic chemicals affect steroid hormones differently in humans and invertebrates
In a study with important consequences for studies on the effects of chemicals on steroid responses in humans, a team of French and American scientists, including Michael E. Baker, PhD, professor in UC San Diego's Department of Medicine, Division of Nephrology-Hypertension, have found that - contrary to earlier assumptions - enzymes used for the... view more...

A brave new "old world" of RNA
A new function for RNA, which further elucidates how genes are expressed and regulated, is described on the 25th of November issue of the journal Nature. view more (2004-11-22)
