Making peanut products a baby food could head off life-threatening peanut allergies later, new data show.
Since the arrival of Europeans in Australia, a startling number of mammal species have disappeared. A new study puts much of the blame on cats and foxes introduced by the early settlers.
Plastics that conduct electricity let new color-changing sunglasses go from dark to light and back again at the tap of a switch. The shades could come in a range of colors too.
More than half of all teens 15 and older get less than seven hours of sleep, according to a new study. That is two to three hours less than recommended. Overall, teens are sleeping less with each passing year, data show.
A new electric keyboard locks out anybody but its owner. It’s not only self-cleaning but also powered by your fingertips.
To better understand how the body heals wounds, scientists have begun creating computer programs that let virtual cells fight it out. These ‘computer games’ could lead to better medicines.
New technologies allow medical experts to create remarkably detailed artificial faces. They can help restore the appearance — and the confidence and self-esteem — of patients who have suffered a disfiguring injury or disease.
New studies and ongoing work highlight why society should save rare livestock breeds — and the part that technology can play.
When added to brain tissue, a chemical like one found in baby diapers expands. And it expands that brain tissue too, giving scientists a better view of how its cells connect.
Beyond the quest for trim waistlines and cavity-free teeth, girls have another reason to shun sodas and other sweetened drinks. These beverages may help launch the body’s menstrual cycles at an earlier age.
Tiny chemical droplets in a liquid sandwiched between panes of glass turn cloudy when they warm up. This will block some sunlight and potentially save on air conditioning bills.
Ancients used to ‘see’ the outline of animals and other well-known things as constellations in the night sky. Now astronomers have done much the same thing. But they’ve spotted a more distant — if totally modern — shape: a smiley face!
In March 2014, scientists claimed to have found the first echoes of the Big Bang — ripples in the very fabric of space. A new analysis shows the experts were mistaken. Dust appears to explain the confusion.
Reading on an iPad in the evening can make it harder to fall asleep — and harder to wake up the next morning, a new study finds. The light from its screen tinkers with the body’s clock. And that could risk harming your health.
Newly analyzed fossils suggest snakes lived at the same time as the golden age of dinosaurs. These early snakes appear to have had flexible skulls and likely also had four small limbs.
Cameras spotted orangutans walking down logging roads to get around. That may be a good sign that they can adapt to changes in their woodsy environment.
Scientists have begun dissecting what it means to be in love. They are finding that much of what we feel can be explained by the effects of a few key chemicals — and not just on our hearts and brains, but on our whole bodies.
The United States is experiencing an outbreak of measles. A traveler likely brought in the virus from abroad, which is now spreading. Most of those infected were never vaccinated and could now face serious health risks.
Many people think that the measles vaccine wiped out the disease — at least in the United States. It hasn’t. And people who were never vaccinated face the primary risk of getting this very serious disease
