New study finds “messy” microscopic structures on petals of some flowers manipulate light to produce a blue colour effect that is easily seen by bee pollinators. Researchers say these petal grooves evolved independently multiple times across flowering plants, but produce the same result: a floral halo of blue-to-ultraviolet light.
A new study shows that even those presumably best informed on the environment find it hard to consistently “walk the walk”, prompting scientists to question whether relying solely on information campaigns will ever be enough.
Early humans seem to have recognised the dangers of inbreeding at least 34,000 years ago, and developed surprisingly sophisticated social and mating networks to avoid it, new research has found.
Massive projected increase in use of antimicrobials in animals could lead to widespread antimicrobial resistance in humans28 Sep 2017
The amount of antimicrobials given to animals destined for human consumption is expected to rise by a staggering 52% and reach 200,000 tonnes by 2030 unless policies are implemented to limit their use, according to new research.
World's botanic gardens contain a third of all known plant species, and help protect the most threatened25 Sep 2017
The most in-depth species survey to date finds an “astonishing array” of plant diversity in the global botanic garden network, including 41% of all endangered species. However, researchers find a significant imbalance between tropical and temperate plants, and say even more capacity should be given to conservation, as there is “no technical reason for plant species to become extinct”.
New research reveals for the first time the most likely months and routes for the spread of new strains of airborne ‘wheat stem rust’ that may endanger global food security by ravaging wheat production across Africa, the Middle East, Asia and the wider world.
In the centenary year of the publication of a seminal treatise on the physical and mathematical principles underpinning nature – On Growth and Form by D’Arcy Wentworth Thompson – a Cambridge physicist has led a study describing an elegantly simple solution to a puzzle that has taxed biologists for centuries: how complex branching patterns of tissues arise.
Researchers have used genome editing technology to reveal the role of a key gene in human embryos in the first few days of development. This is the first time that genome editing has been used to study gene function in human embryos, which could help scientists to better understand the biology of our early development.
