Cucumber genome published

The genome of the cucumber has been sequenced by an international consortium lead by Chinese and U.S. institutions. The annotated genome is published online Nov. 1 by the journal Nature Genetics.

The cucumber genome will give insight into the genetics of the whole cucurbit family, which includes pumpkins and squash, melon and watermelon, and be a platform for research in plant biology, said William Lucas, professor and chair of the Department of Plant Biology at the University of California, Davis. Lucas helped with the development and management of the project.

Rice U. lab leads hunt for new zeolites

In all the world, there are about 200 types of zeolite, a compound of silicon, aluminum and oxygen that gives civilization such things as laundry detergent, kitty litter and gasoline. But thanks to computations by Rice University professor Michael Deem and his colleagues, it appears there are -- or could be -- more types of zeolites than once thought.

A lot more.

The new myths of gifted education

Los Angeles, London, New Delhi, Singapore and Washington DC (November 2, 2009) – More than 25 years after myths about gifted education were first explored, they are all still with us and new ones have been added, according to research published in the current Gifted Child Quarterly (GCQ), the official journal of National Association for Gifted Children.

Biological speed limit slows evolution’s pace, scientists say

PHILADELPHIA –- Researchers at the University of Pennsylvania have developed a theoretical model that informs the understanding of evolution and determines how quickly an organism will evolve using a catalogue of "evolutionary speed limits." The model provides quantitative predictions for the speed of evolution on various "fitness landscapes," the dynamic and varied conditions under which bacteria, viruses and even humans adapt.

Discovery offers potential new pancreatic cancer treatment

Tiny particles that can carry drugs and target cancer cells may offer treatment hope for those suffering with pancreatic cancer. New research to be presented in November at the American Association of Pharmaceutical Scientists (AAPS) Annual Meeting in Los Angeles reveals that tumor-penetrating microparticles (TPM) have been specifically designed to break through hard-to-infiltrate barriers and deliver drugs more effectively and efficiently than the standard form of chemotherapy such as those injected through a vein.

Women who exit welfare just as likely to marry as women never on welfare

NEW YORK—November 2, 2009—A new study from a recent issue of the Journal of Marriage and Family shows that women who exit welfare (under TANF, or Temporary Assistance for Needy Families), are as likely to marry as women of similar socioeconomic backgrounds who were never on welfare. Marriage rates are lower while women receive TANF, but since most women receive welfare benefits for a short period of time, the overall effect of welfare participation on marriage rates is very small.

New activity found for a potential anti-cancer agent

Pateamine A (PatA), a natural product first isolated from marine sponges, has attracted considerable attention as a potential anti-cancer agent, and now a new activity has been found for it, which may reveal yet another anti-cancer mechanism. That's the assessment of Daniel Romo, a Texas A&M chemistry professor, and his colleagues at Johns Hopkins University who are pioneers in research involving this novel marine natural product.

Researchers identify the 3 killer indicators that are even worse than high cholesterol

Researchers at the University of Warwick have identified a particular combination of health problems that can double the risk of heart attack and cause a three-fold increase in the risk of mortality.

The team, led by Assistant Clinical Professor of Public Health at Warwick Medical School Dr Oscar Franco, has discovered that simultaneously having obesity, high blood pressure and high blood sugar are the most dangerous combination of health factors when developing metabolic syndrome.

New clues to the Falklands wolf mystery

Ever since the Falklands wolf was described by Darwin himself, the origin of this now-extinct canid found only on the Falkland Islands far off the east coast of Argentina has remained a mystery. Now, researchers reporting in the November 3rd issue of Current Biology who have compared DNA from four of the world's dozen or so known Falklands wolf museum specimens to that of living canids offer new insight into the evolutionary ancestry of these enigmatic carnivores.

Pdx1 reveals possible origin of pancreatic cancer

Study results: MIT cancer biologists have identified a subpopulation of cells that can give rise to pancreatic cancer. They also found that tumors can form in other, more mature pancreatic cell types, but only when they are injured or inflamed, suggesting that pancreatic cancer can arise from different types of cells depending on the circumstances.

T. rex fossils reveal insights about behavior of young dinosaurs

DeKalb, IL – We all know adolescents get testy from time to time. Thank goodness we don't have young tyrannosaurs running around the neighborhood.

In a new scientific paper, researchers from Northern Illinois University and the Burpee Museum of Natural History in Rockford report that adolescent tyrannosaurs got into some serious scraps with their peers.

The evidence can be found on Jane, the museum's prized juvenile Tyrannosaurus rex, discovered in 2001 in Montana.

Stereotactic radiotherapy stops lung cancer from growing in frail patients

Stereotactic body radiation therapy (SBRT) stopped the growth of cancer at its original site in the lung for three years among nearly 98 percent of patients with early non-small cell lung cancer (NSCLC) who are unable to have the cancer surgically removed, according to an updated three-year study presented November 2, 2009, at the 51st Annual Meeting of the American Society for Radiation Oncology (ASTRO).

Stereotactic radiotherapy offers noninvasive, effective treatment for lung cancer patients

DALLAS – Nov. 2, 2009 – Stereotactic body radiation therapy (SBRT) should be considered a new standard of care for early-stage lung cancer treatment in patients with co-existing medical problems, according to results from a national clinical trial led by UT Southwestern Medical Center physicians.

In this study, 55 patients diagnosed with early non-small-cell lung (NSCL) cancer and unable to have their tumors surgically removed because of unrelated medical comorbidities were treated with SBRT during three noninvasive outpatient treatments.
