GAINESVILLE, Fla. -- University of Florida Health researchers have slowed a notoriously aggressive type of brain tumor in mouse models by using a low-carbohydrate diet.

A high-fat, low-carbohydrate diet that included a coconut oil derivative helped reduce the growth of glioblastoma tumor cells and extended lifespan in mouse models by 50 percent, researchers found. The results were published recently in the journal Clinical Cancer Research.

Glioblastoma, the most common brain tumor in adults, has no effective long-term treatment and on average, patients live for 12 to 15 months after diagnosis, according to the National Cancer Institute.

How did the eruptions of Katmai, Taupo and Santorini grow into a massive blast that spewed fine ash, sulfur and crystal-poor magma into the atmosphere? New research from Georgia Institute of Technology and Eidgenössische Technische Hochschule Zurich (ETH) suggests they occurred due in part to how light vapor bubbles migrate and accumulate in some parts of shallow volcanic chambers. The findings are published online by Nature.

TALLAHASSEE, Fla. -- Commitment to family is both a driving force and source of hardship for Latino immigrants, according to a Florida State University researcher.

Threats to familismo -- deeply held cultural beliefs about the centrality of family in daily life -- are often a major source of stress for immigrants and can have a negative impact on their overall health and well-being as they move forward in a new country.

Joseph Grzywacz, the Norejane Hendrickson professor of Family and Child Sciences at Florida State, outlined those findings in an article that will be published in an upcoming issue of Cultural Diversity and Ethnic Minority Psychology. It is available now online.

RIVERSIDE, Calif. -- Using DNA collected from corn grown by immigrant farmers in Los Angeles and Riverside, researchers at the University of California, Riverside have found the genetic diversity of corn in some home and community gardens in Southern California far exceeds levels found in commercially available seeds.

The researchers cautioned that this is a preliminary study with a small sample size. Future research would expand to include a greater number of gardens, and focus on characteristics of the corn, such as tolerance to drought, difference in cob size and flowering time.

ATLANTA - Month date, 2016-While use of the standard therapy leading to the best outcome against locally advanced rectal cancer has increased over the past decade, only half of patients currently receive it, according to a new study. The authors of the study say the underutilization could be explained in part by socioeconomic factors. The study appears early online in the American Cancer Society's peer-review journal Cancer.

The fungal pathogen Batrachochrytrium dendrobatridis (Bd), which has been known to cause the disease chytridiomycosis and decimate frog populations for close to half a century, is causing frogs to evolve around it, according to a new study which took a step toward identifying the genetic mechanisms that makes some frogs resistant to Bd infections in their study of lowland leopard frogs in Arizona. 

The most comprehensive analysis to date of a series of earthquakes that included a 4.8 magnitude event in East Texas in 2012 didn't find evidence that the earthquakes were caused by wastewater injection - and they the difficulty of trying to claim earthquakes were caused by human activity, at least using currently available subsurface data.

DURHAM, N.C. -- The bearcat. The binturong. Whatever you call this shy, shaggy-haired creature from Southeast Asia, many people who have met one notice the same thing: it smells like a movie theater snack bar.

Most describe it as hot buttered popcorn. And for good reason -- the chemical compound that gives freshly made popcorn its mouthwatering smell is also the major aroma emitted by binturong pee, finds a new study.

Most people have never heard of a binturong, let alone caught a whiff of one up close. But for many zookeepers, the smell wafting from the binturong enclosure is so striking that they name their resident binturongs after the popular snack.

The unique features and blending characters of a new roundworm species, discovered in India, make the nematode a distinct yet intermediary or connecting link between two supposedly distant genera. The new worm is a hermaphrodite that primarily feeds on bacteria. The study, conducted by a research team from the Aligarh Muslim University, India, led by Dr Qudsia Tahseen, is published in the open access Biodiversity Data Journal.
