Kidney Stones :: Kidney stones and nanoparticles
Researchers at Mayo Clinic have successfully isolated nanoparticles from human kidney stones in cell cultures and have isolated proteins, RNA and DNA that appear to be associated with nanoparticles.

Bacteria :: Study finds the air rich with bacteria
The air could be teeming with more than 1,800 types of bacteria, according to a first-of-its-kind census of airborne microbes recently conducted by scientists from the US Department of Energy’s Lawrence Berkeley National Laboratory.
Stem Cell :: Stem cell activity deciphered in the aging brain
Neurobiologists have discovered why the aging brain produces progressively fewer new nerve cells in its learning and memory center. The scientists said the finding, made in rodents, refutes current ideas on how long crucial “progenitor” stem cells persist in the aging brain.
Panton-Valentine leukocidin (PVL) positive community-associated MRSA in the West Midlands
Eight cases of Panton-Valentine leukocidin (PVL) positive community-associated MRSA (CA-MRSA) have been identified among individuals in a hospital and their close household contacts in the West Midlands. Four individuals developed an infection, two of whom died.
Condom :: Chandigarh administration installs condom vending machines
Acting swiftly after a survey by a government hospital said majority of girls did not practise safe sex, the administration here installed condom vending machines in different parts of the city in its bid to sensitise the vulnerable population against AIDS.
Cancer :: How NSAIDs halt cancer growth explained
Scientists have discovered that induction of a gene known as MDA-7/IL-24 is the molecular mechanism that enables nonsteroidal anti-inflammatory drugs (NSAIDs) to halt the growth of cancer cells, a finding that could eventually lead to the development of targeted cancer treatments.
Fertility :: Declining US fertility rates
In the United States, the total fertility rate — the number of children a woman has in her lifetime — fell from seven or eight in 1800 to slightly more than two today, says J. David Hacker, assistant professor of history at Binghamton University. And with a five-year $667,237 grant from the National Institute of Child Health and Human Development, Hacker hopes to find out why.
Stem Cell :: Stem cells found in adult hair follicles may provide alternative to embryonic stem cells
A team from the Medical College of Wisconsin in Milwaukee has applied for a patent on their work to isolate, grow and identify a new and readily-available type of adult stem cell that is found in the bulge of hair follicles, and appears to have a potential for diversification similar to that of embryonic stem cells.
Diabetes :: From managing sugar to managing healing
At the American Society for Cell Biology’s 2006 conference, researchers will report that applying insulin directly to skin wounds significantly enhanced the healing process. Chronic or nonhealing wounds take an immense toll on American health and on health-care systems.
Stem Cell :: Muscle and bone from an ink-jet printer
At the 2006 American Society for Cell Biology conference, scientists present the first research findings of a system that can pattern the formation of multiiple tissues from a single population of adult stem cells.
