Invasive species are both a fact of life and a scientific puzzle. Humans transport animals and plants thousands of miles from where they first evolved — sometimes accidentally, sometimes intentionally. Many of those species die off in their new homes. Some barely eke out an existence. But some become ecological nightmares. In the Northeast, emerald…

In the study of the human mind, old disciplinary boundaries have begun to dissolve and fruitful new relationships between the sciences and humanities have sprung up in their place. When it comes to the cognitive science of language, Stephen Booth may be the most prescient literary critic who ever put pen to paper. In his…

Among their ranks were the largest terrestrial animals of all time, and yet an enduring mystery remains – how did so many animals…

¿Qué tuvo Europa de especial?

Power plants waste huge amount of energy as heat—about 40 to 80 percent of the total in the fuel they burn. A new device could reduce that waste, cutting fuel consumption and carbon emissions by as much as 3 percent and saving companies millions of dollars. (Three percent might not seem like much, but for…

A small peptide helps a silencing construct home in on the adipocytes of obese mice.

To giraffe researchers, the paradox of this keystone African herbivore goes beyond questions of its camouflaging coat. Giraffes may be popular, they said — a staple of zoos, corporate logos and the plush toy industry — but until recently almost nobody studied giraffes in the field.
