1 of life's most common compounds causes allergic inflammation
The beetle's back and the crab's shell owe their toughness to a common compound called chitin that now appears to trigger airway inflammation and possibly asthma, UCSF scientists have found.   view more (2007-04-23)

Weizmann Institute scientists discover a key player in embryonic muscle development
Muscle fibers are large cells that contain many nuclei. They begin, like all animal cells, as naive embryonic cells. These cells differentiate, producing intermediate cells called myoblasts that are now destined to become muscle.   view more (2007-04-12)

Aurora Space Exploration Programme's proposal mulls take off in May
Scientists working with the European Science Foundation (ESF) are putting the finishing touches to an ambitious programme of research for the exploration of the Moon and Mars. They expect to publish their proposals in May.   view more (2007-04-05)

A 'traffic light' for neurons means 'go' for improving brain research
Every thought, feeling and action originates from the electrical signals emitted by diverse brain cells enmeshed in a tangle of circuits. At this fundamental level, scientists struggle to explain the mind.   view more (2007-04-05)

Secret of Worm's Poison Pill Box Protein Could Produce New Natural Insecticide
Researchers at the University of Warwick have discovered how a protein from a bacterium acts like a cunningly designed poison pill box that could now be used as a basis of a new range of natural insecticides.   view more (2007-03-13)

Smithsonian scientists discover new marine species in eastern Pacific
Smithsonian scientists have discovered a biodiversity bounty in the Eastern Pacific—approximately 50 percent of the organisms found in some groups are new to science. The research team spent 11 days in the Eastern Pacific, a unique, understudied region off the coast of Panama.   view more (2007-03-09)

MicroRNA helps prevent tumors
A microRNA directly regulates a gene implicated in human cancers, researchers from Whitehead Institute and Massachusetts Institute of Technology report in the February 22nd online issue of Science.   view more (2007-02-23)

Researchers invent system to control and quarantine worms attacking computer networks
A new anti-worm technology developed by Penn State researchers can not only identify and contain worms milliseconds after a cyber attack, but can also release the information if the quarantine turns out to be unwarranted.   view more (2007-02-09)

Mutant gene shatters nerves
If you bend a knee or an elbow, the nerves in your limbs stretch but do not break. A University of Utah study suggests why: A gene produces a springy protein that keeps nerve cells flexible. When the gene was disabled in tiny nematode worms, their nerve cells literally broke.   view more (2007-01-30)

New clues to how sex evolves
Sex is a boon to evolution; it allows genetic material from parents to recombine, giving rise to a unique new genome. But how did sex itself evolve\\\   view more (2006-12-05)

Mystery solved
Answering a question that has lingered for centuries, a team of scientists has proved that chemicals used to treat the wood used in Stradivarius and Guarneri violins are the reasons for the distinct sound produced by the world-famous instruments.   view more (2006-11-30)

NYU, Scripps finding offers new path for treatment of diabetes
Researchers at New York University and the Scripps Research Institute have discovered a new enzyme, GAPDH, which regulates insulin pathways-a finding that offers a new direction for the treatment of diabetes.   view more (2006-11-28)

Decoded sea urchin genome shows surprising relationship to humans
The Sea Urchin Genome Sequencing Project (SUGSP) Consortium, led by the Human Genome Sequencing Center at Baylor College of Medicine (BCM-HGSC) in Houston, announced today the decoding and analysis of the genome sequence of the sea urchin, Strongylocentrotus purpuratus.   view more (2006-11-10)

Tiny worm provides model for the genetics of nicotine dependence
The unassuming C. elegans nematode worm, a 1-millimeter workhorse of the genetics lab, is quite similar to human beings in its genetic susceptibility to nicotine dependence.   view more (2006-11-03)

Single molecule extends fat mice lives by reversing gene pathways associated with disease in obese
Researchers have used a single compound to increase the lifespan of obese mice, and found that the drug reversed nearly all of the changes in gene expression patterns found in mice on high calorie diets-some of which are associated with diabetes, heart disease, and other significant diseases... view more (2006-11-02)

New species and new records of marine species discovered in NW Hawaiian Islands
A three-week scientific expedition to French Frigate Shoals in the Northwestern Hawaiian Islands Marine National Monument returned to Honolulu on Sunday with the discovery of many new species and a better understanding of marine biodiversity in the Hawaiian Archipelago.   view more (2006-10-31)

Study reveals mechanism for cancer-drug resistance
Using the worm Caenorhabditis elegans, researchers at UT Southwestern Medical Center have discovered a mechanism by which cancer cells become resistant to a specific class of drugs.   view more (2006-10-11)

Targeting wolbachia, doxycycline reduces pathology of lymphatic filariasis
Lymphatic filariasis, a mosquito-borne tropical disease that afflicts 120 million people worldwide, can cause debilitating swelling of the legs and genital areas.   view more (2006-09-20)

'Conversation stoppers' fight deadly bacterial infections
Bacterial infections are becoming more deadly worldwide due to increased resistance to antibiotics. Now, chemists at the University of Wisconsin-Madison have developed a powerful strategy to fight these deadly infections: Instead of killing the bacteria directly, the scientists designed a group of... view more (2006-09-11)

Fast-freeze snapshot yields new picture of nerve-muscle junction
When nerve cells excite muscle fibers to flex, getting synaptic proteins and components into the right place can mean the difference between feats of strength or lapses of drowsy lethargy.   view more (2006-09-08)

Waterborne infectious diseases could soon be consigned to history, says expert
Waterborne infectious diseases, which bring death and illness to millions of people around the world, could largely be consigned to history by 2015 if global health partnerships integrate their programmes.   view more (2006-08-25)

Scientists discover age-regulated cellular activities that protect against protein aggregation
Alzheimer's disease now strikes more than one in 30 Americans, and about half the population that lives past 85 acquires Alzheimer's.   view more (2006-08-14)

'Dead Zone' causing wave of death off Oregon coast
The most severe low-oxygen ocean conditions ever observed on the West Coast of the United States have turned parts of the seafloor off Oregon into a carpet of dead Dungeness crabs and rotting sea worms, a new survey shows. Virtually all of the fish appear to have fled the area.   view more (2006-08-11)

New research points toward mechanism of age-onset toxicity of Alzheimer's protein
Like most neurodegenerative diseases, Alzheimer's disease usually appears late in life, raising the question of whether it is a disastrous consequence of aging or if the toxic protein aggregates that cause the disease simply take a long time to form.   view more (2006-08-11)
