Halving radiation therapy for HPV-related throat cancer offers fewer side effects and similar outcomes, Mayo study finds

Mayo Clinic researchers have found that a 50 percent reduction in the intensity and dose of radiation therapy for patients with HPV-related throat cancer reduced side effects with no loss in survival and no decrease in cure rates. Results of a phase II study were presented today at the 59th Annual Meetingof the American Society for Radiation Oncology in San Diego by Daniel Ma, M.D. a radiation oncologist at Mayo Clinic.

Climate insurance is rarely well thought out in agriculture

Internationally subsidised agricultural insurance is intended to protect farmers in developing countries from the effects of climate change. However, it can also lead to undesirable ecological and social side effects, as UFZ researchers and their US colleagues at the University of Oregon have explained in a review article in the latest issue of Global Environmental Change. The article also contains recommendations for improved insurance schemes which in future should also take account of ecological and social aspects in addition to economic issues.

Antarctic Glacier Loses Chunk of Ice Four Times the Size of Manhattan

A section of ice more than 100 square miles in size — four times as large as Manhattan — has broken off the Pine Island Glacier in West Antarctica. It is the fifth major calving, or ice loss, event on the glacier since 2000.

Emerging Disease Further Jeopardizes North American Frogs

A deadly amphibian disease called severe Perkinsea infections, or SPI, is the cause of many large-scale frog die-offs in the United States, according to a new study by the U.S. Geological Survey.

Frogs and salamanders are currently among the most threatened groups of animals on the planet. The two most common frog diseases, chytridiomycosis and ranavirus infection, are linked to frog population declines worldwide. The new study suggests that that SPI is the third most common infectious disease of frogs.

Globe sees 2nd warmest year to date, 3rd warmest August on record

The final days of August signaled summer’s end for those of us in the Northern Hemisphere. So, how did this summer compare to others?  

For the entire globe, both August and the season (June, July and August) each went down as the third warmest on record. But depending on where you live, the summer you experienced may have felt warmer or cooler than normal.

Technique spots warning signs of extreme events

Many extreme events — from a rogue wave that rises up from calm waters, to an  instability inside a gas turbine, to the sudden extinction of a previously hardy wildlife species — seem to occur without warning. It’s often impossible to predict when such bursts of instability will strike, particularly in systems with a complex and ever-changing mix of players and pieces.
