Why Does Being in the Heat Make Us Feel Tired?
The reason for this lethargy is simple: Your body is working hard to keep you cool, and this extra labor makes you feel tired, said Dr. Michele Casey, the regional medical director at Duke Health in North Carolina. "Your body, especially in the sun, has to work hard to maintain a consistent, normal, internal temperature," Casey told Live Science. This allows warm blood to cool off, releasing heat as it travels near the skin, Casey said.

Shot in the Dark: College Students Don't Know How Strong Their Drinks Are
Young people, in particular, "are really bad at detecting how much alcohol there is in a drink by taste or smell," said Philip Terry, a professor of psychology at Kingston University London. Terry presented his findings Aug. 4 here at the American Psychological Association's annual meeting. To see how well young adults could determine how much alcohol was in a drink, the researchers did two experiment with college students.

Origami Organs: This 'Tissue Paper' Could Help Regenerate a Heart or Uterus
These new "tissue paper" materials retain the cellular properties of the organ, so they could help the body regenerate the relevant organ tissue to aid healing of wounds, scientists said. "Because it has components that are found in the actual tissue in the organs, the cells will recognize it once it's implanted," study co-author Ramille Shah, assistant professor of materials science and engineering at Northwestern University in Evanston, Illinois, said of the tissue paper in a video statement.

Why Fat on Your Hips May Be Healthy
A little extra padding around the hips and thighs may be a good thing, at least if you're of normal weight. A new analysis suggests that lean people who tend to carry fat in their hips and thighs may be at lower risk of heart disease and diabetes than those who tend to carry fat elsewhere in their body. The researchers hypothesize that problems with the way lean people store fat in their lower body could play an important role in their risk of metabolic diseases, such as heart disease and diab

Stoned Plus Buzzed: Mixing Caffeine and Pot Brings New Risks
Eighty percent of Americans get a daily jolt from caffeine, and now, as marijuana legalization has spread across the nation, some users and businesses have begun touting a combination of the two drugs. It's important to keep in mind that the caffeine in a regular cup of coffee or tea is a pretty powerful psychoactive drug, meaning it’s capable of affecting the mind, emotions and behavior, Dr. Sergi Ferre, a senior investigator at the National Institute on Drug Abuse (NIDA), told Live Science.

'Brain Training' Games May Be No Better Than Video Games, Study Finds
Brain-training games such as those from Lumosity may not boost people's overall thinking abilities or help them make "smarter" decisions, a new study suggests. Researchers analyzed information from 128 young adults who were randomly assigned to play either Lumosity games or computer video games for 10 weeks. In contrast, the video games aren't intended to improve cognitive performance and don't adjust in difficulty.

Soap Ingredient May Be Linked to Antibiotic Resistance
Scientists in England have uncovered a possible link between a common antibacterial ingredient and antibiotic resistance. The ingredient, called triclosan, has been on the radar of the U.S. Food and Drug Administration (FDA) for some time. Indeed, in 2016, the FDA banned the ingredient in soaps available to consumers because of both safety concerns and a lack of evidence that soaps with triclosan worked any better than regular soap and water.
