One of the workhorses of in any biology lab is Caenorhabditis elegans or nematode worm just 1mm long. Biologist regularly use C. elegans to gain insight into topics ranging from embryonic development and aging to genetics and neurobiology. In 1986, C. elegans became the first to have its entire nervous system mapped out. This creature, it turns out, contains just 302 neurons with 7000 synaptic connections between them, the fewest of any animal. Scientists hoped that such a map — a connectome â ...read more

Against the backdrop of Southeast Alaska’s glacier-capped peaks, Dana Bloch leans over the side of a small boat and scoops up a clump of orange fecal matter floating in the ocean. “It’s my best sample yet,” she says, peering at the humpback whale poop in her net. “This one’s been feeding on krill instead of fish, so it’s pretty solid.”Bloch is a fellow with the Alaska Whale Foundation and a graduate student at the University of Alaska Fairbanks. She’s also the first person to s ...read more

In fact, most UFO sightings ...read more

With agile leaps and bounds, they traverse the canopy in search of food, communicating among themselves with delicate chitters and whinnies.Seven spider monkey species, found in tropical forests from Mexico to Bolivia, showcase the wonders of primate evolution and play a crucial role in maintaining the forests they call home. They are often seen as forest specialists that need pristine wo ...read more
One of the most common questions I get is whether a nuclear bomb could set off a volcano or trigger an earthquake. You might think that all that energy being released in the explosion would be perfect for getting faults or magma to move. So, would you believe that the United States set three nuclear bombs off in one of the most geologically active parts of the world … and nothing happened?These days it is hard to imagine a world with nuclear testing. However, in the 1940s to 1990s, the US and ...read more
