From today's featured article

Golding Bird (9 December 1814 – 27 October 1854) was a medical doctor who researched the chemistry of urine and kidney stones. From 1836, he lectured at Guy's Hospital and published Elements of Natural Philosophy, a textbook on science for medical students. Bird was innovative in the medical use of electricity, designing his own equipment and bringing medical electrotherapy into the mainstream. He invented a variant of the Daniell cell in 1837, making key discoveries in electrometallurgy. Bird also designed a flexible stethoscope, and in 1840 published the first description of one. In 1842, he was the first to describe oxaluria, a condition which leads to the formation of a particular kind of stone, and published a comprehensive paper on urinary deposits in 1844. A devout Christian, Bird believed that Bible study and prayer were just as important to medical students as their studies. He founded the Christian Medical Association, although it did not become active until after his death. (Full article...)

Rock climber with equipment

Rock-climbing equipment varies with the specific type of climbing undertaken. Bouldering needs the least equipment outside of climbing shoes, climbing chalk and optional crash pads. Sport climbing adds ropes, harnesses, belay devices, and quickdraws to clip into pre-drilled bolts. Traditional climbing adds the need to carry a "rack" of temporary passive and active protection devices. Multi-pitch climbing, and the related big wall climbing, adds devices to assist in ascending and descending fixed ropes. Aid climbing uses unique equipment to give mechanical assistance to the climber in their upward movement. Advances in equipment are a key part of rock-climbing history, starting with the climbing rope. Modern equipment includes dynamic ropes, plyometric training tools, advanced spring-loaded camming devices for protection, and advanced rope control devices such as self-locking devices, progress capture devices, and assisted braking devices.

Today's featured picture

Leucojum vernum, commonly called the spring snowflake, is a species of flowering plant in the family Amaryllidaceae. It is native to central and southern Europe from Belgium to Ukraine. L. vernum is cultivated as an ornamental plant for its white flowers in spring. The plant multiplies in favourable conditions to form clumps. Each plant bears a single white flower with greenish marks near the tip of the tepal, on a stem about 10 to 20 centimetres (3.9 to 7.9 inches) tall, occasionally more. The Latin specific epithet vernum means 'relating to spring'; its close relative, L. aestivum, blooms in summer. This photograph of a L. vernum flower, taken in Bamberg, Germany, was focus-stacked from 32 separate images.
