Health care-associated infections — illnesses that people contract while being treated in a hospital or other health care facility — sicken millions of people each year and cost billions of dollars in additional treatment. While there has been some improvement over the years, on any given day, about 3 percent of the hospitalized population in the United States has at least one health care-associated infection, according to the U.S. Centers for Disease Control and Prevention (CDC).

Engineering professor Lynn Loo, director of the Andlinger Center for Energy and the Environment, says the dangers of climate change are so pressing that it’s time for all hands on deck to decarbonize the U.S. and global economies. She praises the issue awareness behind legislation introduced in Congress to implement a “Green New Deal,” but stresses that solar and wind technologies, by themselves, are not yet sufficient to fuel the nation. “We’re always racing against time,” explains Loo.

Fact: About 66 million years ago, at the end of the Cretaceous period, 75 percent of plant and animal species went extinct, including the dinosaurs (except those that evolved into birds). Fact: About 66 million years ago, an enormous asteroid or comet hit the Earth near what is now Chicxulub, Mexico, throwing rock, dust and water vapor into the atmosphere.

In the tropical jungle of Central America where predators abound, a species of cuckoo has found safety in numbers by building communal nests guarded by two or three breeding pairs.
Why then do these agreeable avians sometimes ditch the collaborative lifestyle and instead deposit eggs into nests outside the communal group, acting like social parasites, in the hopes that other females will raise the chicks as their own?

As the oceans warm in response to climate change, fishing boats in the Mid-Atlantic that focus on only one or two species of fish are traveling more than 250 miles farther north than they did 20 years ago, while others catching a wide diversity of species have not changed fishing location, reported Talia Young, a postdoctoral research associate in ecology and evolutionary biology at Princeton.

Seismologists use waves generated by earthquakes to scan the interior of our planet, much like doctors image their patients using medical tomography. Earth imaging has helped us track down the deep origins of volcanic islands such as Hawaii, and identify the source zones of deep earthquakes.

Sewage treatment — an unglamorous backbone of urban living — could offer a cost-effective way to combat climate change by flushing greenhouse gases from the atmosphere.
