Since the inception of commercial air travel, the insides of airplane cabins have been associated with a higher likelihood of catching a cold or other spreadable disease. New research has sought out to see if scientific facts back up those sentiments.

Study examines how diseases really spread during air travel

Even when it’s not the holiday season, outdoor lighting is on the rise

Technology

‘Tis the season for garish holiday displays. But outdoor lighting is a year-long phenomenon, and it might be having unintended consequences.

Coal

Another way to look at the fossil record? By examining coal.

Science

If you’re like most people, you probably think of coal as a chunk of black fossil fuel. Geologist Jen O’Keefe sees it differently.

Soccer ball

New research finds that heading the soccer ball may be riskier for women than men

Health

They “found that women tended to have damage to a greater part of their brain and to more discrete areas of the brain than the men who headed the ball the same amount.”
