News: Scientists Are Using the Special Physics of Dragonfly Wings to Create Surfaces That Shred Bacteria on Contact

As drug-resistant bacteria become more commonplace, researchers are looking for new antibacterial strategies to disrupt disease-causing microbes. Some scientists are working to create new drugs, while others are trying out drug combinations. Another group, however, are ditching pharmaceuticals altogether and experimenting with non-drug alternatives.

Velveting Meat: The Best-Kept Chinese Restaurant Secret

One of my favorite things about American Chinese food is how easy it is to eat: the pieces are bite-sized, the flavors are addictive, and the meat is always tender and easy to chew. But if you've ever tried to replicate any of your favorite takeout in the kitchen, you've likely noticed that the high heat required for most recipes thoroughly dries out the meat that you're trying to cook.

Better Than Brita: Water Filters with No Plastic Parts

I used a plastic water filter for years. Who wouldn't? It cuts down on buying bottled water, which, as it turns out, is pretty much the same as unfiltered tap water. Plus, bottled water is terrible for the environment and your wallet, too. Water that costs only pennies a day and actually was purified as opposed to just saying it was? That's a no-brainer.

News: This Genetic Defect Could Be Why Typhoid Mary Never Got Typhoid Fever

Whether or not a microbe is successful at establishing an infection depends both on the microbe and the host. Scientists from Duke found that a single DNA change can allow Salmonella typhi, the bacteria that causes typhoid fever, to invade cells. That single genetic variation increased the amount of cholesterol on cell membranes that Salmonella and other bacteria use as a docking station to attach to a cell to invade it. They also found that common cholesterol-lowering drugs protected zebrafi...

News: HIV Prevention Ring Passes Safety Testing Clinical Trial

Young girls, especially those who live in areas where HIV is epidemic, like sub-Saharan Africa, are particularly vulnerable to becoming infected with HIV. A vaginal ring containing the antiviral agent dapivirine has been shown to decrease the chance of developing HIV-1 in adult women over 21 and now in the first step for use in adolescents, the ring has been shown to be safe and well-tolerated in that younger age group.

News: What Are Superbugs? Everything You Need to Know About Antibiotic Resistance

Joe McKenna died when he was 30 years old. A young married man with his future ahead of him, he was cleaning up the station where he worked as a fireman. Struck by a piece of equipment fallen from a shelf, Joe complained of a sore shoulder. Over the next week, Joe worsened and ended up in the hospital. Chilled, feverish, and delirious, his organs shut down from an infection we'd now call septic shock.

How To: Turn a Tortilla into a French Crêpe

Making a good crêpe takes practice and commitment. The batter is rich—most recipes incorporate melted butter, whole milk, and several eggs—and the cooking of the crêpe requires good technique. You have to learn to deposit and swirl just the right amount of batter to get the thinnest possible crêpe, and then learn how to loosen the entire circle and flip it over without tearing or snagging.

News: Free Protein Folding Game Cracks HIV Molecule Riddle

Foldit is definitely a niche game. The sole gameplay mechanic is attempting to fold complex proteins into smaller and more efficient shapes following the rules of molecular physics and biology. Points are awarded based on how small one can make the protein. Online leaderboards track players' relative progress and allows them to view and manipulate other players' completed designs. It's original, certainly, but no developer is going to ship a million units of a game about molecular-level prote...

HowTo: Grow Your Own Snowflakes

CalTech's Kenneth Libbrecht reveals the sublime beauty of snow crystals when photographed with a specially designed snowflake photomicroscope. The physicist is author of the Field Guide to Snowflakes and The Secret Life of a Snowflake, and recently posted an instructional guide for growing your own snow crystals.
