New research promises cure by mouth
A researcher at Aston University in Birmingham has become the first in the UK to investigate a new type of vaccination delivery that could revolutionise how we are protected against diseases including flu, hepatitis and, most excitingly, cancer. Dr Yvonne Perrie from the School of Life & Health Sciences has received a research grant from The... view more... (2002-12-02)
CSHL-led team identifies key decision-point at which cells with broken DNA repair themselves or die
When cells undergo potentially catastrophic damage, for example as a result of exposure to ionizing radiation, they must make a decision: either to fix the damage or program themselves for death, a process called apoptosis. view more (2009-04-13)
'Destruct' triggers may be jammed in tumor cells, UF geneticists say
Tumor cells living in the cross hairs of radiation or chemotherapy may be able to escape death because their self-destruct mechanisms are jammed, say University of Florida scientists writing in a recent issue of Developmental Cell. view more (2008-05-01)
Significant dementia risk attributable to small blood vessel damage
Autopsy data of 221 men and women found that the brains of one-third of individuals who had dementia before death showed evidence of small, cumulative blood vessel damage that can arise from hypertension or diabetes. view more (2008-04-07)
More confusion over cellphone safety
UK CONTACT - Claire Bowles, New Scientist Press Office, London: Tel: +44(0)20 7331 2751 or email claire.bowles@rbi.co.uk Written by Duncan Graham-Rowe THE safety of cellphones has been brought into question once again by research that suggests radio waves from the devices could promote the growth of tumours. Paradoxically, the study suggests that... view more... (2002-10-24)
USC researchers identify key mechanism that occurs at the inception point of many human lymphomas
Researchers at the Keck School of Medicine of the University of Southern California (USC) have explained how certain key mutations occur in human lymphomas-a process that has, until now, remained a mystery. view more (2008-12-12)
Protein helps cells duplicate correctly, avoid becoming cancer
A Purdue University researcher has discovered that the absence of certain proteins needed for proper cell duplication can lead to cancer. view more (2009-10-06)
Selfing DNA prevents genomes from mixing
Genomes of multicellular organisms are one of the greatest mysteries of biology. The more is discovered about them, the more questions are to be answered. One of such questions is connected with the size of a genome. As is known since the middle of the 20th century, the level of organization of an organism does not depend on the genome size, i.e.,... view more... (2002-10-11)
New mechanism found for neurodegenerative effects of amphetamines in mice
University of Toronto researchers have discovered a new mechanism for the neurodegenerative effects of amphetamines. view more (2006-04-06)
Tiny molecule controls stress-induced heart disease
A tiny snippet of RNA, a chemical cousin of DNA, controls damage to the heart under several types of stress, researchers at UT Southwestern Medical Center have found. view more (2007-03-23)
Milestone tumor virus publication by Elsevier journal Virology
A recent special edition of the Elsevier journal Virology reviews the past, present, and future of the exciting field of small DNA tumor viruses. view more (2009-04-10)
Researchers gain insight into mechanism underlying Huntington's
Researchers at the University of Kentucky Markey Cancer Center and Graduate Center for Toxicology (GCT) have gained new insight into the genetic mechanisms underlying Huntington's disease and other neurodegenerative or neuromuscular disorders caused by trinucleotide repeats (or TNRs) in DNA. view more (2009-07-14)
Memory function varies after damage to key area of the brain
Scientists at the University of Liverpool have discovered dramatic differences in the memory performance of patients with damage to the hippocampus, an area of the human brain key to memory. view more (2008-10-23)
When Good DNA Goes Bad: Backward DNA leads to DNA breaks associated with leukemia, study finds
When otherwise normal DNA adopts an unusual shape called Z-DNA, it can lead to the kind of genetic instability associated with cancers such as leukemia and lymphoma. view more (2006-02-13)
Development of DNA drugs gives hope to lupus patients
A generation of DNA-like compounds, class R inhibitory oligonucleotides (INH-ODNs), have been shown to effectively inhibit cells responsible for the chronic autoimmune condition lupus. view more (2009-05-28)
Novel polymer delivers genetic medicine, allows tracking
Theresa M. Reineke, associate professor of chemistry in the College of Science, and colleagues in her lab at Virginia Tech and at the University of Cincinnati have developed a new molecule that can travel into cells, deliver genetic cargo, and packs a beacon so scientists can follow its movements in living systems. view more (2009-10-07)
JILA finds flaw in model describing DNA elasticity
DNA, the biomolecule that provides the blueprint for life, has a lesser-known identity as a stretchy polymer. view more (2007-09-17)
NYU chemists create 'nanorobotic' arm to operate within DNA sequence
New York University chemistry professor Nadrian C. Seeman and his graduate student Baoquan Ding have developed a DNA cassette through which a nanomechanical device can be inserted and function within a DNA array, allowing for the motion of a nanorobotic arm. view more (2006-12-08)
Infection Blocks Lung's Protective Response Against Tobacco Smoke
An infection that often goes undetected can block the lung's natural protective response against tobacco smoke, according to researchers at National Jewish Health. view more (2008-08-20)
Comparing chimp and human DNA
Scientists look to the chimpanzee genome to better understand what is uniquely human about our own. One goal is to find DNA elements that show evidence of rapid evolution in the human lineage. view more (2006-10-13)
