Brain loss

New Scientist (June 16, 2012) reveals the loss of 147 brains from a research laboratory – not stolen, but damaged due to freezer failure.

The world’s largest repository of human brains had freezer failure on May 31, leading to the loss of brains for research, including a rare collection of 53 brains from donors with autism. Researchers at the Harvard Brain Tissue Resource Center at McLean Hospital in Belmont, Massachusetts, only noticed the thaw when they opened the door because both the temperature reading and the two alarms failed to register the problem.

The temperature display still read minus 79 degrees Celsius, and the rising temperature failed to trigger two alarm systems on separate circuits. Camera footage showed that the technical failures were not due to foul play. Currently two internal investigations are underway to determine the cause and why the early warning systems failed.

However, all may not be totally lost. All 53 autistic brains and 12 others had been cut in half, with one half frozen and the other half of each brain preserved in formaldehyde. Formaldehyde has retained the tissue intact and useful. Hence the brain-halves in formaldehyde can still be used for research.

The acacia thorn trees of Kenya

There are nearly 800 species of acacia trees in the world, and most don’t have thorns. The famous "whistling thorn tree" and the Umbrella Thorn tree of Kenya are species of acacia that do have thorns, or spines. Giraffes and other herbivores normally eat thorny acacia foliage, but leave the whistling thorn alone. Usually spines are no deterrent to giraffes. Their long tongues are adapted to strip the leaves from the branches despite the thorns. The thorny acacia like dry and hot conditions. The thorns typically occur in pairs and are 5-8 centimetres (2-3 inches) long. Spines can be straight or curved depending on the species.

It was grown from ancient times, according to the International Society for Horticultural Science (ISHS). It is also commonly called the European cornel. It is native to southern Europe from France to Ukraine as well as Armenia, Azerbaijan, Georgia, Iran, Turkey, Israel, Lebanon, and Syria. The Cornelian cherry tree ( Cornus mas ) can be grown in orchards, but it is often seen in the forests of Georgia where it grows up to 1,350 metres above sea level. It is a medium to large deciduous tree, growing from 5-12 metres tall. The flowers are small with four yellow petals in clusters, which flower in February and March. The Cornus mas has three botanical varieties: (1) var. typica Sanadze with cylindrical red fruits, (2) var. pyriformis Sanadze with pear-shaped red fruits, and (3) var. flava vest with yellow fruits. The fruits are oblong red drupes about 2 centimetres ...
