The war between cats and mice just took a chilling turn, as a team of Russian researchers announces that early exposure to a chemical in cat urine can condition mice not to flee from an approaching cat. This can’t end well for the mice. »
Last night saw the launch of a resupply mission to the ISS atop a Russian Progress rocket — a pretty routine event (as far as firing things into low-earth orbit will ever be routine), but an important one given recent events. Thankfully, it seems like everything went fine and nothing exploded this time around. »
It’s not wise to combine dangerous chemicals that create explosions at home. But this interactive YouTube video allows you to pick and choose from a variety of substances to create your own big bangs from the safety of your computer. It’s really quite fun. »
For 26 years, since researchers first identified the gene responsible for cystic fibrosis, scientists have attempted to use the knowledge to help treat the illness. Now, gene therapy has been shown to help sufferers for the first time. »
If you live near a hospital, you’ve probably seen the sight: a young physician in loose blue scrubs, standing in line at the grocery store. You can’t help but wonder if the young physician is lost. After all, it appears that he or she belongs in an emergency room – not the dairy section. »
Using a little bit of math and a lot of patience, anyone can watch the International Space Station go flying past the Moon. And if you’ve got a DSLR and a telescope handy, you can save that moment in a stunning photo. »
It looks like we might have overestimated how many neighbors we have. New predictions show that the universe might be an emptier place than we imagined. »
A woman in Clallam County, Washington has died of measles. It is the first U.S. death since 2003 to be attributed to the highly infectious disease. State health officials say the woman’s case “illustrates the importance of immunizing as many people as possible to provide a high level of community protection against… »
Given the vastness of space, it may only be a matter of time before we make contact with intelligent extraterrestrials. But how might an alien civilization react to such a monumental meet-and-greet, and can we possibly know their intentions? Here’s what we might expect. »
It’s hip to be square if you’re a seahorse—or rather, it has certain adaptive advantages. Cylindrical tails may be much more popular in the animal kingdom, but the seahorse’s bizarre square-prism tail has far better mechanical properties. »
Have you ever found yourself staring at Facebook, blinking in disbelief because you can’t quite fathom why something is so popular? Well you might just be victim of a network quirk that makes it appear as though something is common—when in fact it’s actually rare.
New color images acquired by NASA’s New Horizon’s spacecraft show us Pluto as we’ve never seen it before—and on its surface appear to be a series of giant spots that scientists can not yet explain. »
Gardens may be an unruly mess on Earth, but in space, we’ll need our vegetable patches to run like well-oiled machines. That’s why researchers at Purdue University are working out the scientifically perfect cocktail of LED light to grow bumper crops in total confinement.
Two swimming pool weather policies have surprised me in recent years. One was when I showed up to swim laps at an outdoor pool as it was beginning to drizzle. “Come on in,” I was told; as long as there was no lightning, the pool was still open. So I had one of my weirdest swims ever: you turn your head out of the… »
Doctors have long observed odd, circular cells in semen. They resemble undeveloped sperm, but scientists have been unable to work out how or why they appear—until now. »
“Lab-on-a-chip” devices – which can carry out several laboratory functions on a single, micro-sized chip – are the result of a quiet scientific revolution over the past few years. For example, they enable doctors to make complex diagnoses instantly from a single drop of blood. »
