Simple new method detects contaminants in life-saving drug
The blood-thinning drug heparin is highly effective when used to prevent and treat blood clots in veins, arteries and lungs, but earlier this year its reputation as a lifesaver was sullied when contaminated heparin products caused serious allergic reactions that led to a large number of deaths.   view more (2008-11-18)

Changes in urine could lead to BSE test for live animals
Researchers have demonstrated that protein levels in urine samples can indicate both the presence and progress of Bovine Spongiform Encephalopathy (BSE) disease in cattle.   view more (2008-09-08)

An ancient protein balances gene activity and silences foreign DNA in bacteria
Compared to humans, bacteria have a much tidier genome. The tiny microorganisms pack their genes closely together, and don't carry around a lot of extraneous DNA, so-called junk DNA that fills in the gaps between genes.   view more (2008-05-16)

DNA fingerprinting simplified
Agarose gel electrophoresis" Most teenagers wouldn't have a clue what this scientific term means, but middle school student Andrew Trigiano knows the protocol inside and out. When Andrew was 12, his father Robert Trigiano, a professor at the University of Tennessee, was looking for an... view more (2008-05-14)

Fast way of spotting multidrug resistant bacteria could help stop outbreaks in hospitals
A type of bacterium widely found on our skin and in the environment has now become a major threat in hospitals where it can cause serious infections, such as pneumonia in severely ill patients.   view more (2007-11-28)

Bioclocks work by controlling chromosome coiling
In recent years, scientists have discovered that biological clocks help organize a dizzying array of biochemical processes in the body. Despite a number of hypotheses, exactly how the microscopic pacemakers in every cell in the body exert such a widespread influence has remained a mystery.   view more (2007-11-26)

New test could help consumers avoid surprise headaches from chocolate, wine
Researchers in California are reporting development of a fast, inexpensive test suitable for home use that could help millions of people avoid those 'out of the blue' headaches that may follow consumption of certain red wines, cheese, chocolate, and other aged or fermented foods.   view more (2007-10-02)

A search for biomarkers for early detection of colorectal cancer
Researchers at the Zhejiang University, Hangzhou have discovered that mimecan and Thioredoxin Domain-Containing Protein 5 (TXNDC5) were differentially expressed in colorectal adenoma.   view more (2007-09-25)

Alternative methods proposed to detect pesticides and antibiotics in water and natural food
Water or food of natural origins (from plants or animals) that we consume on a daily basis can contain unwanted 'supplies' for our organism, such as pesticides or antibiotics.   view more (2007-09-19)

Where Broken DNA is Repaired
Ionizing radiation, toxic chemicals, and other agents continually damage the body's DNA, threatening life and health: unrepaired DNA can lead to mutations, which in turn can lead to diseases like cancer.   view more (2007-08-03)

NMR advance relies on microscopic detector
Detecting the molecular structure of a tiny protein using nuclear magnetic resonance (NMR) currently requires two things: a million-dollar machine the size of a massive SUV, and a large sample of the protein under study.   view more (2007-05-16)

MIT's molecular sieve advances protein research
New MIT technology promises to speed up the accurate sorting of proteins, work that may ultimately aid in the detection and treatment of disease.   view more (2006-09-14)

Chronic Alcohol Exposure Can Affect Brain Protein Expression
Researchers at the University at Buffalo studying the effects of alcohol on the brain, using zebrafish as a model, have identified several novel central nervous system proteins that are affected by chronic alcohol exposure.   view more (2006-08-30)

Scientists construct a physical map of the Drosophila buzzatii genome
An international team of researchers led by the Universitat Aut√≤noma de Barcelona Professor Alfredo Ruiz, has launched in this month's issue of the journal Genome Research the first detailed physical map of the Drosophila buzzatii chromosomes.   view more (2005-06-30)

Life detection instrument passes key test on road to Mars
The dry, dusty, treeless expanse of Chile's Atacama Desert is the most lifeless spot on the face of the Earth, and that's why Alison Skelley and Richard Mathies joined a team of NASA scientists there earlier this month.   view more (2005-06-29)

Sexual chemistry: The science exposed… The Biochemist April 2002 issue
The rise and rise of STIs (p.8) More cases of sexually transmitted infections (STIs) are being reported than ever before — the incidence has doubled in young people since 1995. A recent article in The Times described the scene in one central London genito-urinary medicine (GUM) clinic as... view more (2002-04-03)

Lab-on-a-chip News: A self-organizing nanoparticle-based molecular sieve is developed to identify and separate DNAs or cells
Because living organisms contain millions of different molecules, identifying or separating any single one of these from their natural environment in order to carry out research work or perform diagnoses is quite like looking for a needle in a haystack. A number of molecular separation technologies... view more (2002-03-21)
