A new study led by UNC's Dr. Margaret L. Gourlay, finds that women aged 67 years and older with normal bone mineral density scores may not need screening again for 10 years.

Environmental risk assessment of pharmaceuticals inadequate
The strategies used to assess the environmental risks posed by pharmaceuticals are not enough to protect natural microbial communities, reveals a researcher from the University of Gothenburg (Sweden) who is calling for better environmental risk assessments.

The pre-Columbian Indian societies that once lived in the Amazon rainforests may have been much larger and more advanced than researchers previously realized.

Study confirms HPV genotypes responsible for majority of cervical cancers worldwide
Eight human papillomavirus (HPV) types (16, 18, 45, 33, 31, 52, 58, and 35) are responsible for over 90 percent of all cervical cancer cases worldwide, and should be the target of the next generation vaccines, according to the largest study of HPV genotypes to date, published online first in the Lancet Oncology.

A team of scientists from Singapore led by the Genome Institute of Singapore and the Institute of Molecular and Cell Biology, two biomedical research institutes of Singapore's Agency of Science, Technology and Research (A*STAR), have discovered the most important genes in human embryonic stem cells.

Climate change may alter natural climate cycles of Pacific
While it's still hotly debated among scientists whether climate change causes a shift from the traditional form of El Nino to one known as El Nino Modoki, online in the journal Nature Geoscience, scientists now say that El Nino Modoki affects long-term changes in currents in the North Pacific Ocean.

Biotech collaboration established to commercialize research reagents
The Walter and Eliza Hall Institute of Medical Research in Melbourne, Australia, has entered a collaboration with New Jersey-based medical technology company BD to evaluate and potentially develop for research and diagnostic use some of the institute's reagents.

Conservation of the royal warship Vasa evaluated
The conservation of the royal warship Vasa, which sank in Stockholm on her maiden voyage in 1628 and was raised in 1961, has provided a unique insight into how large waterlogged wooden archaeological relics can be preserved for the future, reveals an evaluation of the conservation program by a researcher at the University of Gothenburg, Sweden.

Researchers at the University of Massachusetts Medical School have uncovered new evidence suggesting that the SOD1 gene, which is implicated in 20 percent of inherited cases of amyotrophic lateral sclerosis (ALS, or Lou Gehrig's disease), also plays a part in sporadic forms of the disease.

Key difference in how TB bacteria degrade doomed proteins
Scientists have discovered a key difference in the way human cells and Mycobacterium tuberculosis bacteria, which cause TB, deliver unwanted proteins to their respective cellular recycling factories.

Effective search terms yield the right information
It does not matter how good a search engine is if the person doing a search does not ask for the desired information in the right way.
