Severe storms have greatly impacted the Southeastern United States over the years. In the winter of 2022, there were more than 200 reported tornadoes and 14 fatalities. The human and economic impact of these severe storms cannot be overstated. A key to dealing with storms and minimizing their severity is early forecasting and detection. The … Read more

Although the human body is externally symmetrical on left and right, it has remarkable left and right asymmetries in the shape, size and positioning of many internal organs, including the heart, lungs, liver, stomach and brain. These asymmetries can range from benign to not-so-benign, causing a range of conditions that affect multiple organs. The left-right … Read more

An internal circadian clock controls distinctive concentric rings of flowering in sunflowers, maximizing visits from pollinators, a new study by plant biologists at the University of California, Davis shows. The U.S. National Science Foundation-supported work is published in eLife. A sunflower head is made up of hundreds of tiny florets. Because of the way sunflowers grow, … Read more

Spread across vast distances, the islands of the tropical Pacific Ocean are thought to have been populated by humans in two distinct migrations beginning approximately 3,330 years ago. The first followed a northern route out of what is today the Philippines and the second followed a southern route from Taiwan and New Guinea. People arrived … Read more

As technologies keep advancing at exponential rates and demand for new devices rises accordingly, miniaturizing systems into chips has become increasingly important. Microelectronics has changed the way electricity is manipulated, enabling sophisticated electronic products that are now an essential part of our daily lives. Similarly, integrated photonics has been revolutionizing the way we control light … Read more

Fossils of a tiny sea creature that died more than half a billion years ago may compel a science textbook rewrite of how brains evolved. A U.S. National Science Foundation-supported study published in Science provides the first detailed description of Cardiodictyon catenulum, a wormlike animal preserved in rocks in China’s southern Yunnan province. Measuring barely half … Read more

The U.S. National Science Foundation today announced a cross-sector partnership with Ericsson, IBM, Intel, and Samsung to support the design of the next generation of semiconductors as part of its Future of Semiconductors (FuSe) initiative. “Future semiconductors and microelectronics will require transdisciplinary research spanning materials, devices, and systems, as well as the engagement of the full spectrum … Read more

During the ice ages of the Pleistocene, the Florida Peninsula regularly grew to twice its current size as glaciers expanded near the planet’s poles, only to be reduced to a series of islands as melting ice returned to the sea during warm periods. All told, glaciers advanced and retreated 17 times, and, according to a … Read more
