Humans are a success story like no other. We are now living in the “Anthropocene” age, meaning much of what we see around us has been made or influenced by people. Amazingly, all humans alive today – from the inhabitants of Tierra del Fuego on the southern tip of the Americas to the Sherpa in the Himalayas and the mountain tribes of Papua New Guinea – came from one common ancestor.

We know that our lineage arose in Africa and quickly spread to the four corners of the globe. But the details are murky. Was there just one population of early humans in Africa at the time? When exactly did we first leave the continent and was there just one exodus? Some scientists believe that all non-Africans today can trace their ancestry back to a single migrant population, while others argue that there were several different waves of migration out of Africa.

Now, three new studies mapping the genetic profiles of more than 200 populations across the world, published in Nature, have started to answer some of these questions.

New research sheds light on how ultrasound could be used to treat psychiatric disorders

A new study in macaque monkeys has shed light on which parts of the brain support credit assignment processes (how the brain links outcomes with its decisions) and, for the first time, how low-intensity transcranial ultrasound stimulation (TUS) can modulate both brain activity and behaviours related to these decision-making and learning processes.

Since the onset of the Covid-19 pandemic, there have been dramatic reductions in hospital admissions for common and severe childhood infections in England, most likely due to social distancing measures, school and workplace closures, and travel restrictions, finds a study published by The BMJ today.

New blood-based test is the first ever to simultaneously identify if a patient has cancer and if it has spread

A publication by University of Oxford researchers describes a new minimally invasive and inexpensive blood test that can identify cancer in patients with non-specific symptoms. The early success of this technology makes it the first blood-based test that not only detects cancer in this population but can simultaneously identify if a cancer has spread.

Alan Davidson Foundation supports ground-breaking Motor Neurone Disease research

A £210,000 donation from the Alan Davidson Foundation (ADF) has been made to the Nuffield Department of Clinical Neurosciences (NDCN) to advance the University’s world leading research into Motor Neurone Disease (MND). The funding will support a project manager for three years to deliver an innovative research project using the genetic causes of MND to develop approaches to early diagnosis and eventually, prevention of all forms of MND.
