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.    

Researchers discover new, abundant enzyme that helps bacteria infect animals

Researchers have discovered a new class of enzymes in hundreds of bacterial species, including some that cause disease in humans and animals. The discovery provides new insights into how bacteria invade their hosts. The research appears this week in Nature Communications.

Asteroid that killed dinosaurs may have sped up bird evolution

Human activities could trigger an altered pattern of evolution similar to what occurred 66 million years ago, when a giant asteroid wiped out the dinosaurs, leaving birds as their only descendants. 

This year's hurricanes are a taste of the future

In a detailed talk about the history and the underlying physics of hurricanes and tropical cyclones, MIT Professor Kerry Emanuel yesterday explained why climate change will cause such storms to become much stronger and reach peak intensity further north, heightening their potential impacts on human lives in coming years.

New book warns climate change is making us sick

In 2008, Jay Lemery, MD, an emergency physician in Colorado, read a commentary about the effects of global climate change on human health. The author was Paul Auerbach, MD, professor of emergency medicine at Stanford and one of the world’s leading authorities on wilderness medicine.

NASA-Produced Damage Maps May Aid Mexico Quake Response

A NASA-produced map of areas likely damaged by the Sept. 19 magnitude 7.1 Raboso earthquake near Mexico City has been provided to Mexican authorities to help responders and groups supporting the response efforts. The quake, which struck 75 miles (120 kilometers) southeast of Mexico City, caused significant loss of life and property damage.

Flint Residents Experienced Decline in Fertility During Lead Water Crisis

In the year after Flint, Michigan changed its water supply to the lead-tainted Flint River, there was decrease in fertility and an increase in fetal deaths among residents, according to an analysis of health statistics by a team of U.S. economists.

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.
