A new study says it isn't just human memories that fade - aging impacts the ability of honey bees to find their way home as well.
Bees are typically impressive navigators, able to wend their way home through complex landscapes after visits to flowers far removed from their nests, even after three to four days of flight time. Mature bees have piloted their way to and from the hive for five to 11 days and old bees have had more than two weeks of flight time but the paper says that aging impairs the bees' ability to extinguish the memory of an unsuitable nest site even after the colony has settled in a new home.
Spanning the Kill Van Kull tidal strait and first opened in 1931, the Bayonne Bridge was the longest in the world until 1978 and is currently the fourth longest steel arch bridge in the world. Today it carries about 20,000 vehicles per day over its four lanes and it was dramatically blown up in the Steven Spielberg-directed 2005 movie "War of the Worlds", starring Tom Cruise and Dakota Fanning.
In 2002, inspired by the events of the 9/11 terrorist attacks at the World Trade Center, eight-year-old Veronica Granite from New Jersey began a petition drive to illuminate her hometown bridge with red, white and blue lights, having seen tricolor lighting atop the Empire State Building during a visit to Liberty State Park.
Think feminists are angry? Many zealots in any movement come across as bitter to outsiders but
Professor Germaine Greer is giving a talk at the Literary Leicester Festival at the University of Leicester and intends to discuss what enormous fun she has had being a fearless international feminist icon and an academic through four decades of change - witnessing the change from the vaguely "Mad Men" period of the '60s, through the bizarre unisex beliefs of the '70s to today, where women get more PhDs than men but still like to have doors opened for them.
Chemotherapy is extremely valuable in killing cancer cells but also takes surrounding tissue with it. Micro-scaled photovoltaic devices may one day be used to deliver chemotherapeutic drugs directly to tumors, rendering chemotherapy less toxic to surrounding tissue, according to findings presented at the AVS 57th International Symposium&Exhibition in Albuquerque.
When a NASA rocket slammed into the Moon last fall, scientists knew they would get information about the composition of the lunar soil at the poles that has never been sampled.
The findings from that NASA mission, called LCROSS for Lunar CRater Observing and Sensing Satellite, are out, and they are interesting to say the least.
The emptied upper stage of a rocket crashed into the Cabeus crater near the Moon's south pole last October. A second spacecraft followed to analyze the ejected debris for signs of water and other constituents of the super-chilled lunar landscape.
A numerical model can't help you finish a marathon, that will take a lot of running, but math can at least help you be the most efficient your body can be.
The best part about the night before a marathon is 'carb'ing up' the night before with a healthy pasta dinner but marathoners in training long before that make many mistakes with their diet, assuming "I'm in training" means they can eat twice as much of anything.
