Data from satellite sensors show that during the Northern Hemisphere’s growing season, the Midwest region of the United States boasts more photosynthetic activity than any other spot on Earth, according to NASA and university scientists.
Healthy plants convert light to energy via photosynthesis, but chlorophyll also emits a fraction of absorbed light as a fluorescent glow that is invisible to the naked eye. The magnitude of the glow is an excellent indicator of the amount of photosynthesis, or gross productivity, of plants in a given region. (more…)
Author Ziolkowski highlights international school construction initiative
What started out as an around-the-world backpacking trek for a recent college graduate turned into a volunteer program that builds hope by constructing schools in some of poorest places on the planet.
Jim Ziolkowski, best-selling author and founder of buildOn, a nonprofit that erects schools in developing countries, shared his experiences and vision during a talk given Tuesday evening, March 11, at the University of Delaware’s Mitchell Hall. (more…)
Over the last three decades U.S. parents have committed filicide — the killing of one’s child — about 3,000 times every year. The horrifying instances are often poorly understood, but a recent study provides the first comprehensive statistical overview of the tragic phenomenon. The authors also suggest underlying hypotheses of motives with the hope of spurring research on filicide prevention.
PROVIDENCE, R.I. [Brown University] — Instances in which parents kill their children may seem so horrifying and tragic that they defy explanation. Published scientific and medical research, meanwhile, doesn’t offer much epidemiological context to help people understand patterns among such heinous crimes. A paper in the March edition of the journal Forensic Science International provides the first comprehensive statistical analysis of filicide in the United States, drawing on 32 years of data on more than 94,000 arrests. The study also explores possible underlying psychiatric and biological underpinnings of filicide. (more…)
The Beinecke Rare Book & Manuscript Library at Yale has announced the winners of the Windham Campbell Literature Prizes. This year’s recipients illustrate the global scale of the prizes, with the eight winning writers hailing from seven countries. The winners in the three categories — fiction, non-fiction, and drama — will receive $150,000 each in recognition of their achievements and to support their ongoing work. (more…)
The heat from warm river waters draining into the Arctic Ocean is contributing to the melting of Arctic sea ice each summer, a new NASA study finds.
A research team led by Son Nghiem of NASA’s Jet Propulsion Laboratory in Pasadena, Calif., used satellite data to measure the surface temperature of the waters discharging from a Canadian river into the icy Beaufort Sea during the summer of 2012. They observed a sudden influx of warm river waters into the sea that rapidly warmed the surface layers of the ocean, enhancing the melting of sea ice. A paper describing the study is now published online in the journal Geophysical Research Letters. (more…)
As a roomful of environmental scientists discussed the 100-pound “bigheaded” carp from Asia invading upper Midwestern rivers, Peter Sorensen thought about the common carp.
A century earlier, that fish had also been introduced and become invasive, causing major aquatic damage that persists to this day. (more…)
“A mood of anxiety seems to pervade American society today,” according to award-winning author and journalist Fareed Zakaria ’86.
“There is a sense in America that the future is not going to be like the past,“ he said. “So much of the energy, so much of the dynamism in the future is no longer quite as true.” (more…)
Yale University has begun a multi-phase renovation of the former Wright Nuclear Structure Laboratory that will reinvent the landmark nuclear physics lab for a new era in physics research.
Expected to take at least three years, the project will transform the bunker-like home of what once was the world’s most powerful atom smasher of its kind into a site for teaching, research, and development related to two of the hottest topics in 21st-century physics — the study of neutrinos and the hunt for dark matter.
