Self-cleaning seabird eggs
Guillemots 鈥� highly social, cliff-nesting seabirds 鈥� lay eggs that are self-cleaning. Scientists studying guillemot eggs accidentally spilled water on a batch. When the accident happened, the researchers noticed that the water stood in droplets on the eggs鈥� surface, similar to the droplets that are seen on lotus leaves or other hydrophobic, water-repellent, self-cleaning surfaces. 大象传媒 Science reporter Victoria Gill heard the scientists鈥� story at the Society for Experimental Biology Conference in Valencia, Spain.

Scarred Liver
Liver disease is on the increase worldwide, due to the rise in hepatitis C in some countries and increasing alcohol use in others. Researchers from the University of Nottingham are exhibiting how new tests, including a technique borrowed from the cheese industry and the use of unique MRI protocols, are being used to diagnose liver disease at an earlier stage. Dr Neil Guha, a liver specialist, and Dr Susan Francis, a physicist, are from the NIHR Nottingham Digestive Diseases Biomedical Research Unit in the UK.
