“For years scientists have been attempting to understand what makes butterflies the masters of manoeuvrability at low speed—able to hover and fly backwards or sideways with apparently little effort,” says The Independent of London. Now researchers at Oxford University believe they have finally found the insect’s secret. Using a specially designed wind tunnel and wisps of smoke to reveal airflow, they observed red admiral butterflies in flight. As the insects flew to and from artificial flowers in the wind tunnel, they were monitored by high-speed digital cameras that recorded the airflow around their wings. The researchers discovered that “the fluttering of butterflies is not a random, erratic wandering, but results from the mastery of a wide array of aerodynamic mechanisms.” Scientists hope to use this knowledge to build remote-controlled aircraft with a wingspan of just a few inches [as small as ten centimeters]. Fitted with a camera, these could be flown into confined spaces as winged observers.

When some large canning companies discontinued using DDT on their crops of corn and peas, they switched to a neural-acting insecticide. This was devastating for bees. Since they have elaborate nervous systems, they are highly sensitive to insecticides such as Sevin, Malathion and Parathion. Sevin seems to be more dangerous because it takes much longer to break down than the latter. The use of Sevin in Minnesota has resulted in bees’ dying in enormous numbers. This has hurt not only beekeepers but also farmers who raise alfalfa, fruit trees and other crops that benefit from the pollinating work of bees.

The ancient Judaean date palms, prized for their beauty, shade, and medicinal properties, were destroyed by the crusaders during the Middle Ages. But now, “Israeli doctors and scientists have succeeded in germinating a date seed nearly 2,000 years old,” reports The New York Times. “The seed, nicknamed Methuselah, was taken from an excavation at Masada,” the cliff fortress conquered by the Romans in 73 C.E. An expert on arid agriculture, Dr. Elaine Solowey, who germinated the seed, notes that it will take years before the young plant produces any fruit, and that only if it is female. “If it’s a male,” she says, “it will just be a curiosity.”

According to a study published in Science magazine, brook trout and other varieties of fish exploit turbulent flows swirling around stationary objects in the water to minimize effort and give themselves an energy-saving boost against the current. By altering their body position and synchronizing movements with the eddies they encounter, says New Scientist, trout save so much energy that they do not have to use their main swimming muscles. “It’s a very low-energy way of moving through a turbulent environment,” explains one of the authors of the study, George Lauder, a biomechanician at Harvard University. In effect, says New Scientist, “the fish were bending their bodies into wing-like hydrofoils to catch the eddies, like a sailboat tacking upwind.”

The British Library is now home to what is believed to be the oldest surviving printed book in the world, reports BBC News. A Buddhist text called The Diamond Sutra bears the date 868 C.E. and was found in 1907 in a cave in Dunhuang, China. “It consists of a scroll of grey paper printed with Chinese characters, wrapped around a wooden pole,” says the report. The book and other items found with it are thought to have been “part of a library which was walled up in the cave around the year 1000AD.” The scroll predates the introduction of movable type into Europe by hundreds of years, but as the BBC report notes, “paper making and printing were already well established in China at the time.”
