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)
More fish oil, less vegetable oil, better for your health
Scientists have provided new evidence that using more fish oil than vegetable oil in the diet decreases the formation of chemicals called prostanoids, which, when produced in excess, increase inflammation in various tissues and organs. view more (2007-07-27)
Only two per cent of child drug trials have independent safety checks
Only two per cent of paediatric drug trials reported using independent safety monitoring committees that can help lead to the early detection of adverse drug reactions, according to a major review published in the journal Acta Paediatrica. view more (2008-03-19)
High-performance computing may improve combustion efficiency
Rising oil prices have revved momentum to develop more efficient combustion systems. But instrumental to this goal is a need to achieve greater understanding of the complex chemical reactions involved in combustion processes. view more (2005-08-30)
Computer predicts reactions between molecules and surfaces, with 'chemical precision'
Good news for heterogeneous catalysis and the hydrogen economy: computers can now be used to make accurate predictions of the reactions of (hydrogen) molecules with surfaces. An international team of researchers, headed by Leiden theoretical chemist Geert-Jan Kroes, published on this subject this week in the journal Science. view more (2009-11-09)
Pitt, NETL researchers report molecular chain reaction thought to be impossible
People said it couldn't be done, but researchers from the University of Pittsburgh and the U.S. Department of Energy National Energy Technology Laboratory (NETL) in Pittsburgh demonstrated a molecular chain reaction on a metal surface, a nanoscale process with sizable potential in areas from nanotechnology to developing information storage... view more...

The Universe, seen under the Gran Sasso mountain, seems to be older than expected
Some nuclear fusion reactions inside stars occur more slowly than we thought and, as a consequence, stars themselves, as well as galaxies and the entire universe are a bit older than expected. This is what comes out from the last results of Luna experiment (Laboratory for Underground Nuclear astrophysics), settled by National Laboratories of Gran... view more... (2004-05-13)
Adapting Space-Industry Technology to Treat Breast Cancer
Researchers at Rush University Medical Center and Argonne National Laboratory are collaborating on a study to determine if an imaging technique used by NASA to inspect the space shuttle can be used to predict tissue damage often experienced by breast cancer patients undergoing radiation therapy. view more (2009-11-03)
Safety checks for GM foods must be better, says Royal Society
Safety assessments should be improved before a greater variety of foods made from genetically modified plants are declared fit for human consumption, a Royal Society report warns today (4 February 2002). The report concludes that there is no reason to doubt the safety of foods made from GM ingredients that are currently available, nor to believe... view more... (2002-02-04)
Families cope better after euthanasia than natural death
The bereaved family and friends of cancer patients who die by euthanasia have less grief symptoms and post-traumatic stress reactions than the bereaved of comparable cancer patients who die a natural death, finds a study in this week's BMJ. Researchers from the Netherlands assessed 189 bereaved family members and close friends of terminally ill... view more... (2003-07-23)
UCR chemists prepare molecules that accelerate chemical reactions for manufacturing drugs
Chemists at the University of California, Riverside have synthesized a new class of carbenes - molecules that have unusual carbon atoms - that is expected to have wide applications in the pharmaceutical industry, ultimately resulting in a reduction in the price of drugs. view more (2005-08-22)
Facial Expressions are Contagious
We meet a smile with a smile, and an angry face with a frown. Facial expressions are very contagious, even on a subconscious level. But if this reaction is pure mimicry or a true reflection of an evoked feeling, is too early to say. Professor Ulf Dimberg, Uppsala University, presents new facts concerning facial expressions in a research report... view more... (2000-03-29)
MIT applies engineering approach to studying biological pathways
An MIT team has used an engineering approach to show that complex biological systems can be studied with simple models developed by measuring what goes into and out of the system. view more (2008-02-07)
How Enzymes Work: UB Chemists Publish A Major Discovery
In a publication selected as a "2007 Hot Article" by the journal Biochemistry, University at Buffalo chemists report the discovery of a central mechanism responsible for the action of the powerful biological catalysts known as enzymes. view more (2007-06-20)
Pediatric researchers find possible 'master switch' gene in juvenile arthritis
Researchers have found that a gene region known to play a role in some varieties of adult rheumatoid arthritis is also present in all types of childhood arthritis. The researchers say the responsible gene may be a "master switch" that helps turn on the debilitating disease. view more (2008-07-02)
Whose body is it anyway? Advertising and male body imagery
A paper on men’s responses to the male image in advertising was given today, Wednesday 20 December, at The British Psychological Society’s London Conference, held at the Institute of Education. Researchers Rosalind Gill and Carl McLean, of the London School of Economics, and Karen Henwood, of the University of East Anglia examined... view more... (2000-12-05)
U-M researchers reveal missing link in a heart disease pathway
University of Michigan scientists and their colleagues have helped characterize a previously unknown link in the chain of biochemical reactions implicated in some forms of heart disease. view more (2007-12-21)
Higher anaphylaxis rates after HPV vaccination: CMAJ study
The estimated rate of anaphylaxis in young women after human papillomavirus (HPV) vaccination was significantly higher - 5 to 20 fold - than that identified in comparable school-based vaccination programs. view more (2008-09-02)
