Superconductors get a boost from pressure
Superconductors can convey more than 150 times more electricity than copper wires because they don't restrict electron movement, the essence of electricity.   view more (2008-05-20)

A new control mechanism for genetic code translation discovered in bacteria
Almost all organisms, from bacteria to human beings, share the same genetic code, a group of universal instructions used to convert DNA or RNA sequences into proteins, the "building blocks" of life.   view more (2008-02-15)

Birth control has long-term effect on hormone exposure
Researchers at Wake Forest University School of Medicine may be one step closer to understanding why past oral contraceptive use dramatically lowers the risk of ovarian and uterine cancers later in life.   view more (2008-10-21)

Inflammatory reaction drives hormone resistance in cancer, study suggests
In the February 10, 2006 Cell, researchers report new evidence to explain why prostate cancer and other hormone-dependent cancers may become resistant to hormone therapies.   view more (2006-02-10)

New study finds anabolic steroids may be addictive
A new study designed to test whether androgenic-anabolic steroids may be addictive found that hamsters exposed to the compounds demonstrated addictive behavior over time.   view more (2005-12-14)

Newly discovered molecular switch helps decide cell type in early embryo development
Researchers have discovered a central molecular switch in fruit fly embryos that opens new avenues for studying the causes of birth defects and cancer in humans. Writing about their study in the Aug. 12 Developmental Cell, scientists at Cincinnati Children's Hospital Medical Center determined the... view more (2008-08-12)

Scientists Identify the “Bin Laden” of Cancer Causing Faulty Proteins
Researchers in the University of Warwick’s Molecular Medicine Research Centre have found the “Bin Laden” of cancer causing faulty proteins. They have undermined the old complex model of how many cancers start and identified a single protein known as c-Myc as a... view more (2002-05-13)

How did chemical constituents essential to life arise on primitive Earth?
Experiments show that simple molecules can combine chemically rather than biologically to form the building blocks of DNA, the key component of all life forms. These processes might have taken place on primitive earth, but how they occur is an unsolved puzzle.   view more (2007-10-31)

No pacemakers in the brain may explain cot death
A failure to 'gasp' has long been proposed as the basis for sudden infant death syndrome, or cot death.   view more (2006-02-13)

A clue to core problem of neurodegenerative disease and cell death
Misfolded and damaged proteins are common to all human neurodegenerative diseases. Clumps of these aggregated proteins destroy neurons within the brain and cause disease.   view more (2006-02-10)

Researchers shed light on shrinking of chromosomes
A human cell contains an enormous 1.8 metres of DNA partitioned into 46 chromosomes.   view more (2007-06-12)

MicroRNA may have fail-safe role in limb development
A tiny strand of molecules plays a role in how our arms and legs develop and grow-a finding that sheds light on perplexing bits of material once dismissed as genetic "junk," say scientists at the University of Florida and Harvard University.   view more (2005-12-02)

For the fruit fly, everything changes after sex
IMP Director Barry Dickson and his group are interested in the genetic basis of innate behaviour. They focus on the reproductive behaviour of the fruit fly Drosophila melanogaster. Two years ago, the team was able to identify the fruitless gene as a key regulator of mating behaviour.   view more (2007-12-11)

When neurons fire up: Study sheds light on rhythms of the brain
In our brains, groups of neurons fire up simultaneously for just milliseconds at a time, in random rhythms, similar to twinkling lightning bugs in our backyards. New research from neuroscientists at Indiana University and the University of Montreal provides a model -- a rhyme and reason -- for this... view more (2008-08-06)

Enzyme crystal structure reveals 'unexpected' genome repair functions
The research looked at XPB helicase from an archaea, a single cell organism similar to bacteria. Helicases are enzymes that unwind or separate the strands of the nucleic acid double helix, an action that is critical to transcription and nucleotide excision repair (NER), as well as other cell... view more (2006-04-07)

MSU's discovery of plant protein holds promise for biofuel production
Scientists at Michigan State University have identified a new protein necessary for chloroplast development. The discovery could ultimately lead to plant varieties tailored specifically for biofuel production.   view more (2008-08-18)

Potential New Therapeutic Target for Asthma, Allergies and Cancer
Virginia Commonwealth University researchers have identified how a bioactive molecule involved with allergy, inflammation and cancer is transported out of mast cells, according to findings published online this week in the Proceedings of the National Academy of Sciences.   view more (2006-10-18)

Was male domination deadly for dinosaurs?
Dinosaurs suddenly died out because they gave birth to too many males as a result of climate change. This is the theory put forward by David Miller of medicine and Jonathen Summers of mechanical engineering at the University of Leeds. They believe that dinosaur populations died out because the sex... view more (2004-05-10)

Weizmann Institute scientists discover a molecular security mechanism for keeping mutations in check
Everyone knows mutations - genetic mistakes in DNA, the material of heredity - are bad: The more mutations in the cell's DNA, the higher the risk of cancer developing.   view more (2006-05-05)

Diversity among bird populations found to reduce threat of West Nile virus
A biologist and undergraduate student have discovered that what's good for an area's bird population is also good for people living nearby.   view more (2008-06-25)

'Sticky' mice lead to discovery of new cause of neurodegenerative disease
When a faulty protein wreaks havoc in cells and causes disease, researchers are usually quick to point the finger at a wayward gene. Now scientists are learning that some neurodegenerative diseases can develop even though a gene is perfectly normal.   view more (2006-08-14)

Enzyme shreds Alzheimer's protein
An enzyme found naturally in the brain snips apart the protein that forms the sludge called amyloid plaque that is one of the hallmarks of Alzheimer's disease (AD), researchers have found.   view more (2006-09-21)

Key mechanism found that promotes spread of malignant melanoma
Researchers at Northwestern University have discovered a key signaling mechanism that may promote the ability of highly aggressive malignant melanoma cells to metastasize, or spread from a primary tumor to distant sites within the body.   view more (2005-11-01)

New target for anti-flu drug development
cientists at Cure Lab, Inc., a biotechnology company based in Canton, Massachusetts, in collaboration with researchers at Boston University and Harvard Medical School have discovered a potential new target for the development of anti-influenza (flu) drugs, including those that may be effective... view more (2007-08-16)

Fat tissue-derived hormone leptin increases e-cadherin expression, obesity-breast cancer link noted
Being obese increases the risk of breast cancer in post-menopausal women, shortens the time between return of the disease and lowers overall survival rates.   view more (2007-04-30)
