South Korea Launches Rocket Into Space, But Satellite Fails to Find Orbit

Just months ago, North Korea set the Japanese and American militaries on alert with its ill-advised, and failed, attempt to send a payload-bearing rocket into space. This morning, a much friendlier South Korea succeeded in doing exactly that, though the research satellite that South Korea Space Launch Vehicle-1 was ferrying ...

Radioactive Cancer-Binding Buckyballs For Targeted Chemotherapy

Chemotherapy is notorious for the toll it takes on the entire body. It kills cancer cells, sure, but it kills a lot of healthy cells, too. But soon a new advance in carbon chemistry may replace the shotgun blast of chemo with a radiation sniper shot. Scientists at Virginia Commonwealth ...

Specially Engineered Bacteria Could Replace Diabetics’ Insulin Shots With Insulin Yogurt Snacks

Developments in genetics are now making it possible to invite custom-engineered symbiotic creatures into our bodies to help perform the functions we can't. In two separate developments, scientists have created a strain of bacteria that stimulates insulin production in the stomach of diabetic mice, and a different strain that produces ...

Battle of the Self-Mutilating Amphibians

In one corner, we have the "hairy" frog, Trichobatrachus robustus, hailing from Cameroon. In the other corner, meet the Spanish ribbed newt, Pleurodeles waltl, hailing from the Iberian peninsula. Which skin-busting, bone-poking amphibian will win the PopSci deathmatch? digg_url = 'http://digg.com/pets_animals/Battle_of_the_Self_Mutilating_Amphibians'; Our frog contender, when provoked, contracts muscles in its front feet, which ...

Warming Oceans May Cause the Earth to Tilt

Global warming and expanding oceans, beyond immediate effects on the surface of our planet, may even cause the earth's axis to shift Human activity has widely affected our planet, reshaping surfaces, moving or extinguishing species, and warming the air and water. Now scientists say our reach has been extended even ...

Too Long For Twitter, Part One

(Agate Beach at Patrick's Point; photo by Neil Mikulenka)In 1978 or 1979, I first went to Patrick's Point State Park near Trinidad in Northern California. It's one of those spots where I instantly felt connection to the sacred. Later I learned it was, indeed, an ancient gathering place for ...

A Portable Device for Frying Electronics

An enemy missile has no strategic value if its computer is down. A high-power-microwave emitter can disable a missile's electronics on the launchpad, leaving bystanders unharmed -- and now Texas Tech University engineers have a plan to scale down the truck-size tech. To make strong microwaves, you need a lot of ...

Custom-Made Metamaterials Could Show Scientists a Tabletop Big Bang

Using materials analogous to different space-times, scientists might be able to create a toy "big bang" in the laboratory For all the visualizations, artist's renderings and animations of the birth of our universe, it is still exceedingly hard to imagine the Big Bang: from nothing emerges everything. But what if ...

Real Genius: Eight Brilliant Inventors Still in High School

While their peers worry about zits, these rising young stars are designing lunar bioreactors and new cancer drugs. What did you accomplish before turning 18? Meet our eight future Edisons here Every year, instead of prepping for prom or hanging out at the mall, thousands of high-school students are busy in ...
