Two-Drug Combination May Eliminate Cancers: New Plan of Attack

Scientists continue search for new ways to treat cancer, creating new drugs and therapies that will hopefully lead to better treatments. Now, though, researchers have developed a "targeted therapy" treatment with a two-drug combination.

Caribbean Island Lizards Reveal Evolution is Predictable

Evolution occurs as environments shift and change, selecting some traits over others. With this in mind, you may think that evolution is unpredictable, depending largely on conditions. Not so, say researchers. Apparently, evolution is extremely predictable—-at least when it comes to Caribbean liza...

NASA Attempts to Resurrect Planet-Hunting Probe, Kepler

NASA's Kepler space telescope has been hunting planets for years. Yet it abruptly stopped its search two months ago after a positioning system failure. Now, the space agency is attempting to get the telescope back on track, so that it hopefully can continue to search for alien planets.

Nondrinkers More at Risk Than Light Drinkers--Unless They Have a Good Reason

Although previous research has shown that people who don't drink at all have a higher mortality risk than light drinkers, scientists have uncovered further evidence that may give more depth to the matter. It turns out that the reasons nondrinkers have for abstaining affects their individual mortalit...

'Invisible' Wetsuit Guards Divers and Surfers Against Shark Attacks in Western Australia

Is it better to be visible or invisible in the water? It all depends on whether you're scuba diving or surfing. Researchers have now developed two different types of wetsuits that can be used to deter sharks, preventing attacks in the water.

Cooler Stars Mean Warmer Planets: Ice Freezes Near Hotter Suns

Astronomers continue to hunt for life on other planets, combing the far reaches of the galaxy as they search for potential host stars. Now, they've discovered a little bit more about what types of stars to search for. It turns out that planets orbiting cooler stars may be more likely to remain ice f...

Giant Viruses Blur Line Between Life and Virus

Viruses are normally tiny, spreading through their hosts as they replicate. Now, though, scientists have uncovered giant viruses from sludge across the world. The new findings have blurred the line between life and viruses which, at present, are not considered to be living beings.

World's Slowest-Moving Tar Pitch Drop Caught on Camera (Video)

Tar pitch is thick and viscous, appearing to be almost solid as it slowly oozes. About 69 years ago, scientists set up a pitch-drop experiment to test exactly how long it would take for a single piece of the black substance to fall into a beaker. Now the experiment is finally over--the researchers h...

Gut Microbes Drive New Species Evolution

Although it may seem like we're just one species, we're actually made up of thousands. Now, scientists have discovered that the microbial companions in our gut may play a crucial and important role in evolution; they can contribute to the origin of new species by reducing the viability of hybrids pr...

Like Humans, Chimpanzees and Orangutans Remember Distant Past Events

Humans and apes share a lot in common. We can solve problems, express emotions and use tools. Now, researchers have discovered something else that we have in common; we can both remember events that happened years in the past.

How Insects Move Without Muscles: Crawling Bugs Inspire Robotic Limbs

Insects creep and crawl against the ground, skitter along tree branches and flit through the air. These movements, though, aren't just powered by muscles. Now, scientists have figured out exactly how insects move, which may provide engineers with new ways to improve the control of robotic and prosth...
