Why do so many sports players and athletes choose to wear the color red when they compete? A new study to be published in Psychological Science, a journal of the Association for Psychological Science, suggests that it may have to do with their testosterone levels.
U of T Engineering researchers, working with colleagues from Carnegie Mellon University, have published new insights into how materials transfer heat, which could lead eventually to smaller, more powerful electronic devices.
Injectable nanoparticles developed at MIT may someday eliminate the need for patients with Type 1 diabetes to constantly monitor their blood-sugar levels and inject themselves with insulin.
The relationship between the heritable risk for schizophrenia and low intelligence (IQ) has not been clear. Schizophrenia is commonly associated with cognitive impairments that may cause functional disability. There are clues that reduced IQ may be linked to the risk for developing schizophrenia. For example, reduced cognitive ability may precede the onset of schiz
Do most scientists agree that human activity is causing global climate change? Yes, they do, according to an extensive analysis of the abstracts or summaries of scientific papers published over the past 20 years, even though public perception tends to be that climate scientists disagree over the fundamental cause of climate change.

Classical X-ray radiographs provide information about internal, absorptive structures of organisms such as bones. Alternatively, X-rays can also image soft tissues throughout early embryonic development of vertebrates. Related to this, a new X-ray method was presented recently in a Nature article published by a German-American-Russian research team led by KIT.
What is the long-range weather forecast for the giant planets Uranus and Neptune? These planets are home to extreme winds blowing at speeds of over 1000 km/hour, hurricane-like storms as large around as Earth, immense weather systems that last for years and fast-flowing jet streams. Both planets feature similar climates, despite the fact that Uranus is tipped on its side with the pole facing the s
City College of New York Assistant Professor of Physics Cory Dean, who recently arrived from Columbia University where he was a post-doctoral researcher, and research teams from Columbia and three other institutions have definitively proven the existence of an effect known as Hofstadter's Butterfly.
Frustration led to revelation when Rice University scientists determined how graphene might be made useful for high-capacity batteries.
Inspired by the structure of moth eyes, researchers at North Carolina State University have developed nanostructures that limit reflection at the interfaces where two thin films meet, suppressing the "thin-film interference" phenomenon commonly observed in nature. This can potentially improve the efficiency of thin-film solar cells and other optoelectronic devices.
Whether we're listening to Bach or the blues, our brains are wired to make music-color connections depending on how the melodies make us feel, according to new research from the University of California, Berkeley. For instance, Mozart's jaunty Flute Concerto No. 1 in G major is most often associated with bright yellow and orange, whereas his dour Requiem in D minor is more likely to be linked to d
When UC Santa Barbara doctoral student Seeta Sistla and her adviser, environmental studies professor Josh Schimel, went north not long ago to study how long-term warming in the Arctic affects carbon storage, they had made certain assumptions.
Invasive "crazy ants" are displacing fire ants in areas across the southeastern United States, according to researchers at The University of Texas at Austin. It's the latest in a history of ant invasions from the southern hemisphere and may prove to have dramatic effects on the ecosystem of the region.
Northwestern University scientists have shown a gene involved in neurodegenerative disease also plays a critical role in the proper function of the circadian clock.
"Spring is like a perhaps hand," wrote the poet E. E. Cummings: "carefully / moving a perhaps / fraction of flower here placing / an inch of air there... / without breaking anything."

Composite and 3-D-printed components will mean jet engines that use 15 percent less fuel.A new generation of engines being developed by the world’s largest jet engine maker, CFM (a partnership between GE and Snecma of France), will allow aircraft to use about 15 percent less fuel—enough to save about $1 million per year per airplane and significantly reduce carbon emissions.

NASA's venerable Mars rover Opportunity has overcome a glitch that put the robot into standby mode late last month, agency officials announced Wednesday."The Opportunity rover is back under ground control, executing a sequence of commands sent by the rover team," NASA officials wrote in a mission update today. "Opportunity is no longer in standby automode and has resumed...
