A molecule in cells that shuts down the expression of genes might be a promising target for new drugs designed to treat glioblastoma, the most frequent and lethal form of brain cancer. The findings suggest that the protein PRMT5 is a possible prognostic factor and therapeutic target for glioblastoma, and they provide a...

A new study from the USDA Animal and Plant Health Inspection Services and the Wildlife Conservation Society demonstrates that it is possible to qualify bison coming from an infected herd as free of brucellosis using quarantine procedures. These bison can then be used to seed conservation herds in other landscapes without the...

The neural crest (NC) is a unique cell population associated with vertebrate evolution. For the first time, these multipotent cells were isolated from zebrafish embryos and maintained and differentiated in culture. The NC progenitors were differentiated into multiple neural crest lineages, contributing to neurons, glial cells,...

A University of Houston scientist is working to develop the next generation of prostate cancer therapies targeted at metabolism. Daniel Frigo is looking at a cascade of biochemical reactions inside the cell, focusing on an enzyme considered a master regulator of metabolism. Frigo wants to unlock...

A new study potentially has significant implications for prenatal testing for major fetal chromosome abnormalities. The study found that in a head-to-head comparison of noninvasive prenatal testing using cell free DNA (cfDNA) to standard screening methods, cfDNA testing (verifi prenatal test, Illumina, Inc.) significantly...

If you've run out of drinking water during a lakeside camping trip, there's a simple solution: Break off a branch from the nearest pine tree, peel away the bark, and slowly pour lake water through the stick. The improvised filter should trap any bacteria, producing fresh, uncontaminated water. In fact, scientists have...

The convergent evolution of tail shapes in diving birds may be driven by foraging style. Birds use their wings and specialized tail to maneuver through the air while flying. It turns out that the purpose of a bird's tail may have also aided in their diversification by allowing them to use a greater variety of foraging...

Blunt force trauma to the skull of a mummy with signs of Chagas disease may support homicide as cause of death, which is similar to previously described South American mummies. Radiocarbon dated to around 1450 -- 1640 AD, skeletal examination indicated that the mummy was likely 20-25 years old at the time of her death, and her...

Cows learn better when housed together, which may help them adjust faster to complex new feeding and milking technologies on the modern farm, a new study finds. Dairy calves become better at learning when a “buddy system” is in place. The study also provides the first evidence that the standard practice of individually housing...

Remember that sound bite you heard on the radio this morning? The grocery items your spouse asked you to pick up? Chances are, you won't. Researchers have found that when it comes to memory, we don't remember things we hear nearly as well as things we see or touch. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/F...

Pay-for-performance has become a major component of health reforms in the United States, the United Kingdom, and other affluent countries. Although the approach has also become popular in the developing world, there has been little evaluation of its impact. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/d...

While there are claims that there has been a hiatus in global average temperatures, no such hiatus has occurred at the extreme end of the temperature spectrum. New research shows extremely hot temperatures over land have dramatically and unequivocally increased in number and area despite claims that the rise in global average...

By analyzing four years of continuous measurements of the Antarctic Circumpolar Current at Drake Passage, the narrowest point in the Southern Ocean, oceanographers have concluded that the current carries 20 percent more water than previous estimates. They also found that the current remains strong all the way to the seafloor....

Estados Unidos revisará sus programas de asistencia a Uganda luego de que el presidente de ese país, Yoweri Museveni, promulgó la Ley Antihomosexualidad, conocida popularmente como la norma “maten a los gays”. Pero activistas advierten que una suspensión de la ayuda podría tener efectos...

Somali Americans develop twice the antibody response to rubella from the current vaccine compared to Caucasians in a new Mayo Clinic study on individualized aspects of immune response.
