DNA barcoding verified the discovery of a highly disconnected crane fly species

Northwestern Europe harbors one of the best known biotas, thanks to the long faunistic and floristic traditions practiced there. However, some animal groups are far better known than others. The diversity of true flies there is fascinating, and undescribed species of flies, midges and gnats are not uncommon.

New key mechanism in cell division discovered

Researchers from the Bellvitge Biomedical Research Institute (IDIBELL) have identified the mechanism by which protein Zds1 regulates a key function in mitosis, the process that occurs immediately before cell division. The result has been achieved in the online edition of the Journal of Cell Science and opens the door to developing targeted and direct therapies against cancer.

'Rare' genetic variants are surprisingly common, life scientists report

A large survey of human genetic variation, published today in Science, shows that rare genetic variants are not so rare after all and offers insights into human diseases.

"I knew there would be rare variation but had no idea there would be so much of it," said the senior author of the research, John Novembre, an assistant professor of ecology and evolutionary biology and of bioinformatics at UCLA.

Weight in pregnancy best controlled by diet, study shows

Pregnant women, including those who are obese or overweight, should be encouraged to minimise weight gain through diet, according to major new research from Queen Mary, University of London.

Piling on excess weight during pregnancy increases the risk of complications for pregnant women but doctors have been cautious in advising women on ways to manage weight for fear of any adverse effect on mother or baby.

Strategies for producing natural and non-natural chemicals by microorganisms

May 17, 2012—Daejeon, the Republic of Korea—In our everyday life, we use gasoline, diesel, plastics, rubbers, and numerous chemicals that are derived from fossil oil through petrochemical refinery processes. Fossil resources are limited and not sustainable. Our world is facing problems associated with climate change and other environmental problems resulted from lavish consumption of fossil fuels. One solution to address these problems is to use renewable, non-food biomass for the production of chemicals, fuels, and materials through biorefineries.

Experts call for clinical trials to test non-skeletal benefits of vitamin D

Chevy Chase, MD—The Endocrine Society's new scientific statement published online today represents the first comprehensive evaluation of both the basic and clinical evidence related to the non-skeletal effects of vitamin D. The statement addresses current research regarding the associations of vitamin D with immune function, hypertension, stroke, skin conditions and maternal/fetal health.

Weight management in pregnancy with diet is beneficial and safe and can reduce complications

For pregnant women, including those who are overweight and obese, following a healthy calorie controlled diet during pregnancy is safe and can reduce the risk of serious complications such as pre-eclampsia, diabetes and premature birth, finds a study published on bmj.com today.

Open heart surgery for kidney disease patients

Highlight

  • One type of open heart surgery is safer than the other—in terms of both health and survival—for chronic kidney disease patients.
  • Heart disease is the leading cause of death in individuals with chronic kidney disease.

Washington, DC (May 17, 2012) — One type of open heart surgery is likely safer than the other for chronic kidney disease (CKD) patients, according to a study appearing in an upcoming issue of the Journal of the American Society of Nephrology (JASN).

Simple procedure lowers blood pressure in kidney disease patients

Highlights

  • A minimally invasive procedure called renal denervation, which disrupts certain nerves in the kidneys, lowers blood pressure in patients with chronic kidney disease and hypertension.
  • The procedure may help protect the kidneys and reduce heart risks in patients with chronic kidney disease.

60 million people globally have chronic kidney disease.

Google goes cancer: Researchers use search engine algorithm to find cancer biomarkers

The strategy used by Google to decide which pages are relevant for a search query can also be used to determine which proteins in a patient's cancer are relevant for the disease progression. Researchers from Dresden University of Technology, Germany, have used a modified version of Google's PageRank algorithm to rank about 20,000 proteins by their genetic relevance to the progression of pancreatic cancer.

Resolving the ortholog conjecture

Researchers at the SIB Swiss Institute of Bioinformatics and the EMBL-European Bioinformatics Institute have confirmed the long-held conjecture that studying the genes we share with other animals is a viable means of extrapolating information about human biology. The study, published in the open access journal PLoS Computational Biology, shows how bioinformatics makes it possible to test the conjecture.

We can learn a lot from other species

Researchers at the SIB Swiss Institute of Bioinformatics and the EMBL-European Bioinformatics Institute have confirmed the long-held belief that studying the genes we share with other animals is useful. The study, published today in the open access journal PLoS Computational Biology, shows how bioinformatics makes it possible to test the fundamental principles on which life science is built.

Tiny tool can play big role against tuberculosis, UF researcher finds

A tiny filter could have a big impact around the world in the fight against tuberculosis. Using the traditional microscope-based diagnosis method as a starting point, a University of Florida lung disease specialist and colleagues in Brazil have devised a way to detect more cases of the bacterial infection.

UF researchers name new extinct giant turtle found near world's largest snake

GAINESVILLE, Fla. --- University of Florida researchers have described a new extinct giant turtle species from the same Colombian mine where they discovered Titanoboa – and one of the only animals the world's largest snake could not have eaten.

Penn and Genographic Project scientists illuminate the ancient history of circumarctic peoples

PHILADELPHIA — Two studies led by scientists from the University of Pennsylvania and National Geographic's Genographic Project reveal new information about the migration patterns of the first humans to settle the Americas. The studies identify the historical relationships among various groups of Native American and First Nations peoples and present the first clear evidence of the genetic impact of the groups' cultural practices.
