January 17, 2013 Flu viruses hijack the machinery inside animal cells to replicate. The theft is a complicated process that takes time. If the virus leaves the cells too early or too late, the risk of infection falls.
January 17, 2013 Some of the most beloved nature writers of all time, Henry David Thoreau and Aldo Leopold, are helping scientists learn how global warming will affect spring. Using historical records, the scientists are able to predict when flowers will bloom during especially hot years.
January 17, 2013 Prawns will rub themselves when dabbed with acid. And hermit crabs show stress-related behavior after getting shocked out of their shells. Now scientists find that British shore crabs can learn to avoid an electric shock — a key sign that crustaceans really do experience pain.
January 11, 2013 We know we need to eat more whole grains like whole-wheat bread, but white bread crust gives off chemicals that smell better to most of us. To combat this, manufacturers add sugar to whole-wheat foods, but this can make them less healthy.
January 9, 2013 An experimental drug developed to fight Alzheimer's disease partially reversed hearing loss caused by exposure to extremely loud sounds, researchers say. The results apply only to mice, but scientists are encouraged by the fact that the medicine caused new hair cells to grow in the animals' inner ears.
January 9, 2013 Top schools often offer scholarships that not only include free tuition, but also free room and board for top students from poor families. Each year, however, colleges are confronted with a paradox: No matter how many incentives they provide, enrollment of highly talented, low-income student barely seems to budge.
January 8, 2013 The contaminants researchers found at the bottom of Alberta lakes are from air pollutants coming from tar sands oil production and processing facilities. The pollution wasn't picked up by the industry-funded monitoring program that was supposed to track environmental risks from tar sands over recent decades.
January 7, 2013 It's important to science and trade that a kilogram in one part of the world weigh the same as others. But particles in the air may be adding microscopic amounts of weight to some of the "official" kilograms around the world. Scientists have a new method of cleaning those weights.
January 4, 2013 Developed by British researchers, Larry the robot has helped scientists see that a little vomit can go a long way. He vomits on command. And his barf can be tagged with fluorescent dye that makes it easy for scientists to track.
