One reason racism persists is that many people imagine they would respond strongly to a racist act but actually respond with indifference, a new study led by York University shows.

Rapidly warming climate is likely to seriously alter crop yields in the tropics and subtropics by the end of this century and, without adaptation, will leave half the world's population facing serious food shortages, new research shows.

In 1913 Theodore Roosevelt added cartographer to his resume when he and his crew ventured up an unspeakably dangerous and uncharted tributary named the River of Doubt. Now, on a charting expedition of their own, Rockefeller University scientists have completed a journey that has also defied expectation.

That pesky buzz of a nearby mosquito is the sound of love, scientists have known for some time. But a new Cornell study reports that males and females flap their wings and change their tune to create a harmonic duet just before mating.

As a chemical for industrial processes, butanol is used in everything from brake fluid, to paint thinners, to plastics. According to a University of Illinois researcher, butanol made from plant material could displace butanol made from petroleum, just not at the fuel pump.

Scientists have identified the structure of a key component of the bacteria behind such diseases as whooping cough, peptic stomach ulcers and Legionnaires' disease.

Masses of immune cells that form as a hallmark of tuberculosis (TB) have long been thought to be the body's way of trying to protect itself by literally walling off the bacteria. But a new study in the January 9th issue of the journal Cell, a Cell Press publication, offers evidence that the TB bacteria actually sends signals that encourage the growth of those organized granuloma structures

Two previously identified pathways associated with aging in mice are connected, say researchers at the Stanford University School of Medicine. The finding reinforces what researchers have recently begun to suspect: that the age-related degeneration of tissues, organs and, yes, even facial skin with which we all struggle is an active, deliberate process rather than a gradual failure of tired cells.

In ant society, workers normally give up reproducing themselves to care for their queen's offspring, who are their brothers and sisters. When workers try to cheat and have their own kids in the queen's presence, their peers swiftly attack and physically restrain them from reproducing.

The nuclei of ordinary hydrogen atoms contain only a single proton. If a neutron is added, the hydrogen becomes deuterium. In principle, molecules that contain deuterium in place of hydrogen atoms are chemically identical. However, there can be significant differences.

The evolutionary history of diatoms -- abundant oceanic plankton that remove billions of tons of carbon dioxide from the air each year -- needs to be rewritten, according to a new Cornell study. The findings suggest that after a sudden rise in species numbers, diatoms abruptly declined about 33 million years ago -- trends that coincided with severe global cooling.

A major goal of nanotechnology research is to create a "lab on a chip," in which a tiny biological sample would be carried through microscopic channels for processing. This could make possible portable, fast-acting detectors for disease organisms or food-borne pathogens, rapid DNA sequencing and other tests that now take hours or days.

Learning To See In Stereo
Children born with a crossed eye can develop a condition called amblyopia that leaves them unable to see in stereo as adults. Conventional wisdom holds that vision stops improving around age 7, but now researchers believe adults with this condition can train their brains to gain stereo vision.

Morning Edition visits an ephemeral pond in the Australian desert, where a sudden downpour has flushed out 11 species of frogs. In their chorus, they signal to mates and mark territory. The segment is part of "Sounds Wild," a series of short, sound-rich stories from remote parts of the planet that are home to rare animals.

Did Earth's twin cores spark plate tectonics?
It's a classic image from every youngster's science textbook: a cutaway image of Earth's interior. The brown crust is paper-thin; the warm mantle orange, the seething liquid of the outer core yellow, and at the center the core, a ball of solid, red-hot iron. Now a new theory aims to rewrite it all by proposing the seemingly impossible: Earth has not one but two inner cores.
