A new economics paper has some old-fashioned advice for people navigating the stresses of life: Find a spouse who is also your best friend.
People who have upbeat outlooks on life have significantly better cardiovascular health, suggests a new study that examined associations between optimism and heart health in more than 5,100 adults.
Since the discovery that DNA encodes genetic information, research on the evolution of life has focused on its genetic origins. Following this “genes-first” approach, Oxford University evolutionary biologist Richard Dawkins has argued in his book The Selfish Gene that cells and organisms evolved simply as packages to ever-more efficiently protect and transmit genes.
Is evolution possible without reproduction? Bacteria living hundreds of metres below the seafloor carry more genetic changes than their peers nearer the surface – even though the deep microbes are unlikely to reproduce and undergo natural selection in its traditional sense.
Polar bears and other Arctic animals are shifting their distributions toward icier regions, according to new research suggesting that at least some species are attempting to adapt to climate-related changes in their habitat, such as dramatic losses of sea ice.

In a mountain meadow in Colorado, ecologists have come across yet another example of the amazing interconnectedness of nature’s flora and fauna. Black bears, by eating ants, help one of the meadow’s key plant species thrive.

A friend can make even the shiest creature bold. Rats usually fear strange open spaces, but having a companion by their side makes the rodents more intrepid, scientists report in the current issue of Animal Cognition. Researchers tracked rats’ exploration of a large, unfamiliar room, first alone, then again 2 days later either alone or paired with a familiar cagemate.
Soon you'll be able to grow your own gut. Take a small sample of human intestine, grind it up and soak it in a digestive enzyme solution, pipette the mixture onto a polymer scaffold and implant it into the abdominal cavity of a mouse. A few weeks later, you'll have a tiny segment of fully functioning human gut.
An unusual butterfly that is half male and half female recently caught the eyes of a volunteer at a butterfly exhibit at Drexel University in Philadelphia.
Sometimes a male chimp just needs to drum. Hooting and hollering, he gallops up to the giant buttress root of a tree, grips its crest with his hands, and beats on its wall-like surface with both feet, making a racket that can be heard more than a kilometer away. Now, new research from Uganda suggests these drum solos contain signature rhythmic patterns that may telegraph an individual’s whereabouts to distant troopmates. The findings could provide insight into how rhythm first evolved in humans.
Tilda, a female orangutan at the Cologne Zoo in Germany, appears to have figured out that if she communicates like a person, she can better grab the attention of zookeepers.

Unlike humans and great apes, rhesus monkeys don't realize when they look in a mirror that it is their own face looking back at them. But, according to a new report, that doesn't mean they can't learn. What's more, once rhesus monkeys in the study developed mirror self-recognition, they continued to use mirrors spontaneously to explore parts of their bodies they normally don't see.
The song of the swamp sparrow -- a grey-breasted bird found in wetlands throughout much of North America -- is a simple melodious trill. But according to a new study swamp sparrows are capable of processing the notes that make up their simple songs in more sophisticated ways than previously realized -- an ability that may help researchers better understand the perceptual building blocks that enable language in humans.
It’s pretty obvious that dogs have sharper ears and cats a keener sense of smell than we do. But as powerful these senses are, they are merely keener versions of the ones we humans possess. The animal kingdom also boast some senses that are arguably more impressive—senses that are far more exotic than our pets’, and that seem unfathomable to the human brain.

Ketamine, a psychoactive ‘party drug’ better known as Special K, has pharmaceutical companies riding high. Used clinically as an anaesthetic in animals and humans, it has proved an extremely effective treatment for depression, bipolar disorder and suicidal behaviour.
