If you're ever lost in a remote European forest, you might be able to get your bearings by finding a herd of roe deer. These animals like to align themselves roughly north-south, whether they're standing still or fleeing danger.
Roe deer are small, reddish or grayish grazers common in Europe and Asia. Petr Obleser, of the Czech University of Life Sciences in Prague, and his coauthors studied the behavior of these skittish herbivores to look for evidence that they can sense the earth's ma........ Read more »
Morels and several other fungi (all members of the order Pezizales) are known to produce their mushrooms in recently burned soil, whether it's the result of a nice little campfire or an entire forest going up in smoke. The fire creates the right conditions for the fungus, which lies beneath the ground and so protected from flames and heat, to send up mushrooms. These mushrooms release spores into the environment, and the circle of life continues ever onward.In the case of morels, it's thought a ........ Read more »

In the mountains of Central Africa, scientists who study critically endangered gorillas have a new tool. They've discovered that they can learn what viruses gorillas are carrying by stealthily collecting half-chewed plants the apes leave behind.
If this sounds reminiscent of that class clown at the third-grade lunch table who would ask if you liked seafood and then say "See? Food!" and open his mouth wide to display his sloppy Joe slurry, don't worry—mountain gorillas are vegetarians. ........ Read more »

The music theory literature has been suggesting it for a long time: the idea that simultaneous sounding tones with frequency relationships that are low integer multiples, like 1:2 (octave) or 3:2 (a perfect fifth), are determinant of how listeners perceive consonance. It is an idea that is often related to the overtone structure of natural sounds (such as the voice or string instruments) suggesting that musical harmony is reflective or even a result of the acoustic structure that is found in nat........

In the open ocean, it's good to have friends. Some young fish like to buddy up with stinging jellies to stay safe from predators. Hiding under the shelter of a jellyfish's bell, they can grow up unharmed (as long as they dodge its tentacles). These fish include some species that humans rely on for food. But in a warming ocean, that buddy system may fall apart.

I love curries. My favorite is Indian tikka masala which is prepared with tomato, yogurt and many different spices including turmeric, ginger, garlic, cardamom, cumin, paprika, cloves and cinnamon. But I’m not the only one, because the passion for spicy dishes is shared among humans of all regions and ages. We eat them fresh, dried, whole, ground, raw or cooked, and our love for these tasty substances led explorers such as Polo, Magellan and Columbus to undertake risky expeditions in searc........

The antibiotic arms race is on, while we are rushing to find new antibiotics, bacteria are working on finding ways around them. With that in mind, a new experimental antibiotic developed by a team of scientists successfully treats the deadly MRSA infection and restores the efficacy of a commonly prescribed antibiotic that has become ineffective against MRSA.

Life on Earth was born in water. Then, about half a billion years ago, the first organisms stare colonizing lands that offered new spaces, less predators and, in time, abundant oxygen and nutrients. Still, the indissoluble bond that living organisms had with water remained, and in order to survive in this new environment plants and animals had to develop anatomical, physiological and behavioral adaptations to better obtain, manage and save water. Plant bodies, as well as ours, are mostly made of........ Read more »

Smog has been a part of modern life since the industrial revolution, unfortunately all that pollution isn't just hurting the environment -- but come on, you saw this coming... right?

More and more studies show that the brain and human cognitive development are affected by pollution.
