Men Strive To Give More To Charity When The Fundraiser Is Cute

Originally published on Fri April 17, 2015 5:28 pm

We donate to charities for lots of reasons: because we're generally magnanimous people, because we care deeply about certain issues or because it's the only way to get Meg to stop talking about the plight of the endangered proboscis monkey.

And for men, there may be another force at play: a subconscious desire to impress the ladies.

Is It Sexist To Say That Women Are Superior To Men?

"Women are not equal to men; they are superior in many ways, and in most ways that will count in the future. It is not just a matter of culture or upbringing. It is a matter of chromosomes, genes, hormones, and nerve circuits. It is not mainly because of how experience shapes women, but because of intrinsic differences in the body and the brain."

How Almonds Became A Scapegoat For California's Drought

Originally published on Thu April 16, 2015 10:05 am

You may have heard by now that it takes one gallon of water to produce just one almond. And those are considered fighting words in drought-stricken California, which produces 80 percent of the world's supply of the tasty and nutritious nut.

So when almond grower Daniel Bays hears that, he just shakes his head.

A common pain medication might make you go from "so cute!" to "so what?" when you look at a photo of a kitten. And it might make you less sensitive to horrifying things, too. It's acetaminophen, the active ingredient in Tylenol. Researchers say the drug might be taking the edge off emotions — not just pain.

Nut So Fast, Kind Bars: FDA Smacks Snacks On Health Claims

Originally published on Mon April 20, 2015 4:30 pm

According to the Food and Drug Administration, there were four flavors of Kind bar that were misbranded when the agency reviewed them in August 2014.

If you're deciding between a candy bar and a fruit-and-nut bar, and health is top of mind, the best choice seems obvious.

But when it comes to companies actually labeling their products "healthy," the Food and Drug Administration is showing it won't pull any punches. In a letter dated March 17 that was released this week, the agency called out the snack food company Kind for violating labeling rules by putting the word "healthy" on the packaging for some of its bars.

Scientists working in East Africa say they've unearthed the oldest stone tools ever found. They were apparently made 500,000 years before the human lineage evolved.

A team led by Sonia Harmand from Stony Brook University in New York found the tools in Kenya, near Lake Turkana. It's an area that's yielded numerous fossils and tools from early humans.

Personalizing Cancer Treatment With Genetic Tests Can Be Tricky

Originally published on Wed April 15, 2015 6:52 pm

Sequencing the genes of a cancer cell turns up lots of genetic mutations — but some of them are harmless. The goal is to figure out which mutations are the troublemakers.

It's becoming routine for cancer doctors to order a detailed genetic test of a patient's tumor to help guide treatment, but often those results are ambiguous. Researchers writing in Science Translational Medicine Wednesday say there's a way to make these expensive tests more useful.

Here's the issue: These genomic tests scan hundreds or even thousands of genes looking for mutations that cause or promote cancer growth. In the process, they uncover many mutations that scientists simply don't know how to interpret — some may be harmless.

U.S. Predicted To Be Net Energy Exporter In Next Decade; First Time Since 1950s

Originally published on Wed April 15, 2015 6:13 pm

The U.S. will reach a new balance in energy trade "sometime between 2020 and 2030," says the Energy Information Administration, which predicts the U.S. could become a net energy exporter in the near future.

The federal agency's prediction cites a rise in domestic natural gas production and changes in energy demands. If it happens, the shift would end a streak of more than 50 years in which the U.S. has been a net importer of energy.
