- People confront prejudice only when they believe others' personalities can change, study finds
Confronting someone who makes a prejudiced remark can be a good thing -- but not everyone does it. Researchers studied how and when targets of bias will speak up, and found that they're more likely to do so if they hold a particular belief: that people's personalities can change.

Much like two children in the back seat of a car, it can be challenging to get two catalysts to cooperate for the greater good. Now chemists have gotten two catalysts to work together -- something easily done by nature but a difficult thing to do in the laboratory. The findings will allow medicinal chemists to invent new reactions and produce valuable bioactive compounds faster with less impact on...

Rows of tiny raised blowfly corneas may be the key to easy manufacturing of biomimetic surfaces, surfaces that mimic the properties of biological tissues, according to researchers.

Drug delivery inside the body is a complicated process. Compounds travel through a maze of aqueous solutions, lipid membranes, and barriers between the blood and tissues like the brain. New research presents a theoretical model that accurately predicts the hydration free energy (HFE) of a wide variety of organic compounds.

Researchers saw an unusual pattern when they looked at a "skymap" of the relative intensity of cosmic rays directed toward the Earth's Southern Hemisphere, with an excess of cosmic rays detected in one part of the sky and a deficit in another. A similar lopsidedness, called "anisotropy," has been seen from the Northern Hemisphere by previous experiments, but its source is still a mystery.

Research reveals that an enzyme linked with multiple disorders -- including stroke, cancer and rheumatoid arthritis -- is also involved in the generation of toxic protein fragments in Huntington's disease.

For decades research has shown that listening to music alleviates anxiety and depression, enhances mood, and can increase cognitive functioning, such as spatial awareness. However, until now, research has not addressed how we listen to music. For instance, is the cognitive benefit still the same if we listen to music whilst performing a task, rather than before it? Further, how does our preference...

The prevalence of early repolarization pattern among 35- to 54-year-olds is higher than previously thought, and has a clear link to an increased risk of cardiac death, especially among men, according to a new study.

Researchers have developed a new, carbon-based nanoscale platform to electrically detect single DNA molecules. Using electric fields, the tiny DNA strands are pushed through nanoscale-sized thin pores in a graphene nanopore platform that ultimately may be important for fast electronic sequencing of the four chemical bases of DNA based on their unique electrical signature.

Stronger suction is required to smoke "electronic cigarettes" than conventional brands, with possible adverse effects on human health, researchers report. Using a smoking machine to compare the smoking properties of eight conventional cigarettes with five e-cigarette brands, the researchers also found that in the case of e-cigarettes, the aerosol density dropped after the first ten puffs, requirin...
