Latest research suggests a new mechanism for how sexual displays of red beaks and plumage might be ‘honest signals’ of mate quality, as genes that convert yellow dietary pigments into red share cofactors with enzymes that aid detoxification – hinting that redness is a genetic sign of the ability to better metabolise harmful substances.
A study of butterflies suggests that when a species adapts, other parts of its genetic make-up can be linked to that adaptation, limiting diversity in the population.
Tiny coffin excavated at Giza in 1907 is remarkable evidence of importance placed on official burial rituals in ancient Egypt.
Claire Spottiswoode (Department of Zoology) and Marjorie Sorensen (Goethe University Frankfurt am Main) discuss why several species of migratory songbirds sing a great deal in Africa when their breeding grounds are thousands of kilometres away.
The wide diversity of flu in pigs across multiple continents, mostly introduced from humans, highlights the significant potential of new swine flu strains emerging, according to a new study.
Does nature make you happy? Crowdsourcing app looks at relationship between the outdoors and wellbeing26 Apr 2016
A new app will crowdsource data to help scientists understand the relationship between biodiversity and wellbeing. The app, developed at the University of Cambridge, maps happiness onto a detailed map that includes all the UK’s nature reserves and green spaces.
Baboons learn about food locations socially through monitoring the behaviour of those around them. While proximity to others is the key to acquiring information, research shows that accessing food depends on the complex hierarchies of a baboon troop, and those lower down the pecking order can end up queuing for leftovers.
Latest analysis shows that human limbs share a genetic programme with the gills of cartilaginous fishes such as sharks and skates, providing evidence to support a century-old theory on the origin of limbs that had been widely discounted.
A 520 million-year-old fossilised nervous system – so well-preserved that individually fossilised nerves are visible – is the most complete and best example yet found, and could help unravel how the nervous system evolved in early animals.
