The Cheetah: One of Nature’s Great Survivors

The African cheetah (Acinonyx jubatus) is the world’s fastest land mammal. It has numerous physiological adaptations that allow it to reach speeds over 100 km/hr including elongated legs, slim aerodynamic skull, enlarged adrenal glands, liver and heart, and semi-retractable claws that grip the earth. Modern cheetahs range across eastern and southern Africa, with a small […]

Bed Bug Genome Sequenced in a Bid to Fight Back Against this Pest

The bed bug genome is one of the many arthropod genomes to be sequenced in the i5K project. The i5K initiative is a transformative project that aims to sequence the genomes of 5,000 arthropod species, to benefit worldwide agriculture, medicine, food safety and ecology. Scientists hope to utilise the bed bug genome to develop new […]

Grey Squirrel Invasion Given A Helping Hand By Humans

Native to the eastern half of North America, grey squirrels were first introduced to Britain in the 1870s and are now widely distributed across the UK. It was originally thought that their ability to cope with new landscapes allowed this rapid spread and by interbreeding with different grey squirrel populations a ‘supersquirrel’ evolved which was […]

UK Approves First Studies of Gene Editing on Human Embryos

The UK’s Human Fertilisation and Embryo Authority (HFEA) has given its approval for studies using the gene-editing technique CRISPR to be used in human embryos. This is the first time UK scientists have been given approval to use DNA-altering techniques in human embryos. The research team will be led by Dr Kathy Niakan at the […]
