Scientists isolate genes that made 1918 flu lethal
By mixing and matching a contemporary flu virus with the "Spanish flu" - a virus that killed between 20 and 50 million people 90 years ago in history's most devastating outbreak of infectious disease - researchers have identified a set of three genes that helped underpin the extraordinary virulence of the 1918 virus. view more (2008-12-30)
Hebrew University Young Researcher Award Goes To Dr. Nayef Jarrous
Dr. Nayef Jarrous, a young researcher from Shfaram in the north of Israel, is the recipient of the Yoram Ben-Porath Prize as this year's outstanding young researcher at the Hebrew University of Jerusalem. The Ben-Porath Prize is awarded annually by the president of the Hebrew University to honor the memory of the former rector and president of the... view more... (2004-01-08)
Frog molecule could provide drug treatment for brain tumours
Known as Amphinase, the molecule recognises the sugary coating found on a tumour cell and binds to its surface before invading the cell and inactivating the RNA it contains, causing the tumour to die. view more (2007-06-27)
UC Davis researchers identify a cellular pathway that makes prostate cancer fatal
Expanding evidence that tiny strands of RNA - called microRNAs - play big roles in the progress of some cancers, UC Davis researchers have identified one that helps jump start prostate cancer cell growth midway through the disease process, eventually causing it to become fatal. view more (2007-11-28)
New compound effectively treats fungal infections
A new mechanism to attack hard-to-treat fungal infections has been revealed by scientists from the biotech company Anacor Pharmaceuticals Inc., California, and the European Molecular Biology Laboratory [EMBL] outstation in Grenoble, France. view more (2007-06-25)
Microbiology Today February 2003 issue
DNA50 and microbes This special issue commemorates the 50th anniversary of the publication of the structure of DNA by Watson and Crick. Microbes have always played an important role in DNA research and this issue, which features topics in modern molecular microbiology and microbial genomics, shows the enormous amount of progress made in the last... view more...

Details of the life cycle of SARS coronavirus
A team of scientists studying Severe Acute Respiratory Syndrome (SARS) has, for the first time, described how the SARS virus manufactures several of the materials required for making copies of itself. "It is essential, when you are looking for ways to stop a disease, that you know exactly how viruses make copies of themselves and... view more... (2003-07-08)
Prediction of gene function in mammals
Gene function in mammals can be quickly and reliably predicted using a high-throughput analysis of patterns of RNA expression, according to an article published today in Journal of Biology. This challenges the conventional view that tissue-specificity is the best predictor of function, and could speed up the quest to understand whole genomes, in... view more... (2004-12-02)
UC Santa Barbara scientists clarify molecular basis of interferon action
Scientists at the University of California, Santa Barbara have made a significant discovery relating to viral infections in humans. view more (2007-07-20)
Massive gene screening points way to more effective chemotherapy
Using a technology that can quickly screen all 20,000-plus human genes for biological activity, scientists have isolated 87 genes that seem to affect how sensitive human cancer cells are to certain chemotherapy drugs. view more (2007-04-12)
UVA researchers find that hotel guests with colds can leave their germs behind after checkout
A group of researchers led by a team from the University of Virginia Health System found that adults infected with rhinovirus, the cause of half of all colds, may contaminate many objects used in daily life, leaving an infectious gift for others who follow them. view more (2006-10-02)
Hepatitis C helicase unwinds DNA in a spring-loaded, 3-step process
The process by which genes are duplicated is mysterious and complex, involving a cast of characters with diverse talents and the ability to play well with others in extremely close quarters. view more (2007-07-27)
New route for heredity bypasses DNA
A group of scientists in Princeton's Department of Ecology and Evolutionary Biology has uncovered a new biological mechanism that could provide a clearer window into a cell's inner workings. view more (2008-01-07)
RNA emerges from DNA's shadow
RNA, the transporter of genetic information within the cell, has emerged from the shadow of DNA to become one of the hottest research areas of molecular biology, with implications for many diseases as well as understanding of evolution. view more (2008-07-11)
Features of replication suggest viruses have common themes, vulnerabilities
A study of the reproductive apparatus of a model virus is bolstering the idea that broad classes of viruses - including those that cause important human diseases such as AIDS, SARS and hepatitis C - have features in common that could eventually make them vulnerable to broad-spectrum antiviral agents. view more (2007-08-14)
Small RNA plays parallel roles in bacterial metabolism
They are often overlooked, and were once thought to be too small to contribute much to major cellular processes, but in recent years the study of small ribonucleic acids (sRNA) has gained momentum. view more (2007-11-30)
MicroRNAs may be key to HIV's ability to hide, evade drugs, Jefferson scientists find
Tiny pieces of genetic material called microRNA (miRNA), better known for its roles in cancer, could be a key to unlocking the secrets of how HIV, the AIDS virus, evades detection, hiding in the immune system. view more (2007-10-01)
Scientists discover new role for miRNA in leukemia
Scientists here have found that mini-molecules called micro-RNA may play a critical role in the progression of chronic myeloid leukemia (CML) from its more treatable chronic phase to a life-threatening phase, called blast crisis. view more (2007-12-10)
Rapid movements of living biomolecules visualised
Dutch researcher Chris Molenaar has made the rapid movements of proteins, DNA and RNA molecules visible in living cells. With this technique researchers can study the dynamics of biomolecules in their natural environment. Molenaar developed a method which makes it possible to follow the movements of RNA molecules in living cells. The researcher... view more... (2003-06-24)
University of Pittsburgh discovers genetic 'shut down' trigger in healthy immune cells
A fundamental genetic mechanism that shuts down an important gene in healthy immune system cells has been discovered that could one day lead to new therapies against infections, leukemia and other cancers. view more (2007-05-10)
