A new study suggests that college students may handle stressful situations better if they have a pet. Research has already shown that pets can improve the quality of life for people who are aging or those who are chronically ill. But researchers at Ohio State University recently found that many college students may also benefit from owning a cat or a dog.
In March of 2008, in a speech addressing contemporary racial tensions in America, then-Senator Barack Obama suggested that there is a "chasm of misunderstanding that exists between the races." Could this be true? Is it more difficult for members of different races to understand each others' emotions and intentions?

When you first notice a door handle, your brain has already been hard at work. Your visual system first sees the handle, then it sends information to various parts of the brain, which go on to decipher out the details, such as color and the direction the handle is pointing. As the information about an object is sent further along the various brain pathways, more and more details are noticed--in that way, a simple door handle turns into a silver-plated-antique-style-door-handle-facing-right.
Scientists at the Instituto Gulbenkian de Ciencia (IGC) and the Faculty of Science of the University of Lisbon, in Portugal, have shown that populations of the worm Caenhorabditis elegans become resistance to pesticides in 20 generations, that is, in only 80 days.
Honeybees are important to plants for reasons that go beyond pollination, according to a new study published in the December 23rd issue of Current Biology. The insects' buzz also defends plants against the caterpillars that would otherwise munch on them undisturbed.
A newly hatched sea turtle's first swim is the most critical of its life. Having run the gauntlet of air and land predators to make it to the sea, the tiny voyager must also evade hungry fish patrolling the beaches in its bid for freedom. For youngsters hatching on the Great Barrier Reef's coral cays the risks are high: as many as 30% perish as they head for safe deep waters. But how much does this headlong dash through the waves cost the intrepid hatchlings?
A widespread and severe coral bleaching episode is predicted to cause immense damage to some of the world's most important marine environments over the next few months.
Anyone who has watched crime dramas on TV knows that forensic scientists can use DNA "profiling" to identify people from evidence gathered at a crime scene, establish a paternity link or help free an innocent person who has been wrongly jailed.
