Pfizer's ZYVOX(TM) more effective than vancomycin in treating complicated SSTIs caused by MRSA
Clinical cure rates were significantly better in patients treated with Pfizer's antibiotic ZYVOX™ (linezolid injection, tablets and for oral suspension) for complicated skin and soft tissue infections caused by known methicillin-resistant Staphylococcus aureus (MRSA) compared to patients treated with intravenous (IV) vancomycin.

Are the bright colors of some avian eggs signaling female genetic quality to their mates?
In Ecology Letters, September, Moreno and Osorno interpret vibrant egg colours as sexually selected signals of laying females' genetic quality to their mates in order to induce them to work harder for offspring that will inherit advertised traits.

Electronics interconnections for extreme space environments
George Harman of NIST recently made a workshop presentation for National Aeronautics and Space Administration (NASA) engineers at the Jet Propulsion Laboratory on designing semiconductor device interconnections to withstand extreme space environments.

From genome comparisons, UCSD researchers learn lessons about evolution and cancer
Bioinformatics experts at UC San Diego -- who posited that 'fragile' regions exist in the human genome that are more susceptible to gene rearrangements -- are now collaborating with biologists to see if their new theory can yield potentially life-saving insights into diseases such as breast cancer, in which chromosomal rearrangements are implicated.

Sugar coupled to protein causes kidneys to save water
Several new mechanisms that are important for the production and transport of water channels to the cell surface of kidneys have been identified by a Dutch researcher.

Jefferson and Michigan scientists identify gene defect behind muscle-wasting disease
Scientists at Jefferson Medical College and the University of Michigan have uncovered a gene defect responsible for a muscle-wasting, neurodegenerative disease in mice known as mnd2.

Bone cement only controls bacteria for a few days after the operation
Dutch research has revealed that bone cement containing antibiotics can effectively control infections around prostheses but only during the first few days after the implantation.

Bright autumn colouration in trees - a warning signal to insects?
There is considerable variation both in the timing and magnitude of autumn colour change.

Not batty conservation
Protecting contemporary biodiversity from human activities that threaten life on earth requires a global network of reserves.

Cow's resistance to worms is genetically determined
Research carried out in the Netherlands has revealed that the genetic background of cattle apparently determines how quickly and effectively they acquire immunity to infections from gastrointestinal worms.

Gray wolves feed the masses while hunters feed the few
Gray wolves (Canis lupus) and human hunters both provide resource subsidies to scavengers in Yellowstone National Park, USA, provisioning them with the remains of their kills.

Sizable federal grant to fund Stanford genome research
Researchers at Stanford University Medical Center received an $8 million boost for their efforts to tease out the most biologically important regions of the human genome.

Vanished super-ocean or expanding Earth?
Matching geological outlines and hundreds of trans-Pacific disjunctions of identical or closely related, poor-dispersing taxa, both fossil and extant, imply a close, terrestrial connection between the western Americas and East Asia/Australia/New Zealand during the Mesozoic.

VIDI awards: Seventy-nine young scientists start their own line of research
The Netherlands Organisation for Scientific Research (NWO) has awarded a so-called VIDI Grant to 79 young, excellent scientists.

Attack of the crazy ants - invasional 'meltdown' on an oceanic island
Biological invasions have direct effects on native ecosystems but may also unleash forces with complex, unexpected consequences.

Mayo Clinic finds weight not a factor among women using fertility technologies to become pregnant
Impaired uterine function is not the cause of lower birth rates among overweight women using fertility technologies to become pregnant, according to a Mayo Clinic study published in the August 2003 issue of Fertility and Sterility.

New Penn study shows genes may influence smoking cessation
Smokers with a specific combination of two genetic variants may be more likely to remain abstinent and less prone to relapse when trying to quit smoking, a study by researchers from the Tobacco Use Research Center of the University of Pennsylvania School of Medicine indicates.

New gene necessary for plant growth and development discovered
By taking a fresh approach to an old problem, University of California, San Diego biologists and colleagues at other institutions have found a new gene essential for plant growth, a discovery that could lead to the design of better herbicides and even novelty plants.

Rabbit and cow graze together
According to Dutch researcher Liesbeth Bakker, rabbits prefer grassland grazed by cows.

Microscopic cracks spoil the transparency of glass, nano-researchers find
Starting with a simple kitchen recipe, Lehigh University scientists find that the nanosurface of molten glass is solid, not liquid, and thus sustains microscopic fractures when exposed to air.
