Two things are clear from a University of Michigan analysis of nearly 200,000 Twitter posts between 2012 and 2022. One, people are really good at identifying peak pollen season: The largest volume of tweets about pollen often ...

A new study from Bar-Ilan University shows that one of sleep's core functions originated hundreds of millions of years ago in jellyfish and sea anemones, among the earliest creatures with nervous systems. By tracing this ...

Detecting cancer in the earliest stages could dramatically reduce cancer deaths because cancers are usually easier to treat when caught early. To help achieve that goal, MIT and Microsoft researchers are using artificial ...

A collaborative team of researchers from the Donald Danforth Plant Science Center, the University of Florida, Gainesville and University of Iowa have developed tools that allow grasses—including major grain crops like corn—to ...

Plants mobilize their immune defenses far earlier than scientists have believed for decades—and through a previously overlooked early signaling mechanism—according to a new study published in Nature Plants.

Astronomers have captured the most detailed look yet at faraway galaxies at the peak of their youth, an active time when the adolescent galaxies were fervently producing new stars.

An international team of researchers led by Hokkaido University has characterized the unique mechanics that enable Arcella, a shelled, single-celled amoeba, to move skillfully across different surfaces.

The mid-ocean ridge runs through the oceans like a suture. Where Earth's plates move apart, new oceanic crust is continuously formed. This is often accompanied by magmatism and hydrothermal activity. Seawater seeps into the ...

For centuries, scientists have known that plants "breathe" through microscopic pores on their leaves called stomata. These tiny valves are the gatekeepers that balance the intake of carbon dioxide into the leaf for photosynthesis ...

Yeast left over from brewing beer can be transformed into edible "scaffolds" for cultivated meat—sometimes known as lab-grown meat—which could offer a more sustainable, cost-effective alternative to current methods, according ...

Earth system box models are essential tools for reconstructing long-term climatic and environmental evolution and uncovering Earth system mechanisms. To overcome the spatiotemporal resolution limitations of current deep-time ...

Chemists from the National University of Singapore (NUS) have developed a single-atom photocatalytic strategy that enables oxidant-free cross-dehydrogenative coupling (CDC) reactions between ring-shaped aromatic molecules ...
