Chile's Torres Del Paine is famous for its stunning landscapes, but it's also home to a fierce predator: the puma. These majestic creatures feed primarily on guanacos, although the hunting success rate is not very high, especially for female pumas. The photographer followed this female and her two cubs for several days, before witnessing her hunting. Breakthroughs, discoveries, and DIY tips sent six days a week. In Chile's famous Torres Del Paine National Park, a mother puma with her two cubs in tow attacks a guanaco.

Science Biology Evolution Biologists discover gene that may determine'good' and'bad' dads Social cues and surprising genetics may affect mammal fathers. Breakthroughs, discoveries, and DIY tips sent six days a week. Most mammals grow up in single parent homes. It's estimated that over 95 percent of the planet's nearly 6,000 known mammalian species rely almost exclusively on mothers to nurture and raise their offspring. But even when dads stick around, it's not always smooth sailing.

Environment Animals Wildlife World's smallest possum may be hiding in South Australia The tiny mammal weighs less than one pound. Breakthroughs, discoveries, and DIY tips sent six days a week. Weighing less than one pound, the little pygmy possum () is one of the smallest mammals in Australia. These miniscule mammals feed on nectar, pollen, and insects, and differ from opossums . Opossums live in the United States and parts of Canada and have a bare tail instead of a furry tail.

The birds can make good pets, but only if taken care of properly. Breakthroughs, discoveries, and DIY tips sent six days a week. Rescuers in North Carolina recently saved over 500 pigeons from a home in Greensboro. Guildford County Animal Services and two other bird rescues based in Charlotte initially believed that the call was for about 300 birds . Instead, they found about 550 pigeons inside of a shed behind the home, hidden from the street.

Environment Animals Wildlife Spiders Psychologists made people look at spiders. Humans will try to focus on almost anything else. Breakthroughs, discoveries, and DIY tips sent six days a week. There are plenty of studies examining why humans are so hardwired to detest spiders . However, fewer researchers have spent time investigating just far we'll go to avoid even looking at them.At the University of Nebraska-Lincoln, psychologists decided to find out for themselves.

Environment Yosemite's glowing, golden waterfall is flowing again The annual natural phenomenon event is expected to last until February 26. Breakthroughs, discoveries, and DIY tips sent six days a week. As if California's Yosemite National Park wasn't magical enough, its famous El Capitan rock formation is graced with an exhilarating phenomenon every February. The Horsetail Fall--a waterfall that falls across the formation's eastern side--can take on an otherworldly gleam during the latter part of the month. During those gorgeous moments, the water flow looks like a stream of gold hurtling down the rock face, and it's hard to believe that it's just nature doing its thing.

Environment Animals Wildlife Elephants are smart. Their 1,000 whiskers make them dextrous enough to pick up a tortilla chip. Breakthroughs, discoveries, and DIY tips sent six days a week. An elephant's trunk is a wonder of evolution. Gentle, yet dextrous, it can pick up solid items, help them communicate, and be a helpful showering too l.

Breakthroughs, discoveries, and DIY tips sent six days a week. Ladybugs are famously harbingers of good luck, and the trait proved consistent at a university in Japan when researchers found a new species of the iconic insect directly on the campus. Ladybugs, also known as ladybird beetles or lady beetles, consist of the family within the order of beetles (). The newly identified member is a black, and researchers discovered it on a pine tree at Kyushu University's Hakozaki Satellite. In fact, its species name means "pine dweller."

Noisy ships and industry are impacting critically endangered Kemp's ridley sea turtles. Breakthroughs, discoveries, and DIY tips sent six days a week. For the world's smallest sea turtles, life in the ocean is getting pretty noisy. These relatively little turtles (on average they're still 75 to 100 pounds) mostly found in the Gulf of Mexico already face fishing gear accidents, seacraft collisions, plastic pollution, and habitat deterioration, and now excess noise may be harming the critically endangered and rare Kemp's ridley sea turtles (). We say because even though these sea turtles share waters with extremely busy shipping lanes, scientists know very little about their underwater hearing.

Experiment in one of the world's quietest rooms reveals the hairs detect airborne sounds--like predators. Breakthroughs, discoveries, and DIY tips sent six days a week. Have you ever walked into a room full of caterpillars? While the answer for most people is probably no, those of us who have may have noticed the insects reacting to the sound of your voice. That's what happened to Carol Miles, a biologist at Binghamton University in New York.
