Americans are getting more ZZZZs

Although more than one in three Americans still don't get enough sleep, a new analysis shows first signs of success in the fight for more shut eye.

Why animals diversified on Earth: Cancer research provides clues

Can tumors teach us about animal evolution on Earth? Researchers believe so and now present a novel hypothesis of why animal diversity increased dramatically on Earth about half a billion years ago. A biological innovation may have been key.

Reminding people about vaccinations can increase rates of immunization

Rates of immunization against infectious diseases in children and adults are improving, but under-vaccination remains a problem that results in vaccine-preventable deaths and illnesses.

Paleolithic diet healthier for overweight women

Overweight women after menopause who eat a Paleolithic diet can maintain weight loss in the long term. The levels of risk factors of type 2 diabetes and cardiovascular diseases also decrease.

Hunter-gatherers have a special way with smells

When it comes to naming colors, most people do so with ease. But, for odors, it's much harder to find the words. One notable exception to this rule is found among the Jahai people, hunter-gatherers living in the Malay Peninsula. For them, odors are just as easy to name as colors. Now a new study suggests that the Jahai's special way with smell is related to their hunting and gathering lifestyle.

College branding makes beer more salient to underage students

Major beer companies have rolled out marketing campaigns and products -- such as 'fan cans,' store displays, and billboard ads -- that pair beer with university colors, mascots, and logos. Research shows that such campaigns may enhance the motivational significance of marketed beer brands, especially for students who identify strongly with their university. The researchers conclude that this effect could potentially increase underage students' alcohol consumption.

Flu may be spread just by breathing

It is easier to spread the influenza virus (flu) than previously thought, according to a new study. People commonly believe that they can catch the flu by exposure to droplets from an infected person's coughs or sneezes or by touching contaminated surfaces. But, new information about flu transmission reveals that we may pass the flu to others just by breathing.

Babies' babbling betters brains, language

Babies are adept at getting what they need -- including an education. New research shows that babies organize mothers' verbal responses, which promotes more effective language instruction, and infant babbling is the key.

Convergent evolution of gene regulation in humans and mice

Organisms that aren't closely related may evolve similar traits as they adapt to similar challenges. It's called convergent evolution, and familiar examples include the wings of birds, bats, and insects, and echolocation in bats and dolphins. Now, molecular biologists have found evidence of convergent evolution in an important mechanism of gene regulation in humans and mice.

Single blood test screens for eight cancer types

Researchers have developed a single blood test that screens for eight common cancer types and helps identify the location of the cancer.
