Scientists studied kefir, one of the world’s oldest fermented food products, and surprisingly found that the dominant species of Lactobacillus bacteria found in kefir grains cannot survive on their own in milk, the other key ingredient in kefir. However, when the species work together – feeding on each other’s metabolites in the kefir culture – they each provide something the other needs.

Experts in airway bitter taste receptors and medicinal chemistry collaborate in efforts to advance a treatment for respiratory diseases, that works differently from existing bronchodilators.

The healing process that follows a brain injury – from trauma to infection and stroke – could encourage tumor growth, according to a new study published in Nature Cancer.

Using multiple mouse models, researchers demonstrate that liver metastases are able to siphon activated CD8+ T cells from the systemic circulation and recruit immunosuppressive macrophages capable of promoting T cell death within the liver. The study, published in Nature Medicine, could be key to understanding why patients with liver metastases typically have a poor response to immunotherapy.

At 7.30 am today, dialysis patient Brian Pinker became the very first person to be vaccinated as part of the UK’s rollout of the Oxford / AstraZeneca coronavirus vaccine, ChAdOx1 nCoV-19, with patients at the Oxford University NHS Hospitals Trust becoming the first to receive this life-saving vaccine.

Two new studies have uncovered an association between vaping and mental fog. Both adults and kids who vape were more likely to report difficulty concentrating, remembering, or making decisions than their non-vaping, non-smoking peers.

The introduction of computer simulation to the identification of symptoms in children with attention deficit/hyperactivity disorder (ADHD) has potential to provide an additional objective tool to gauge the presence and severity of behavioral problems, suggests a new study.

Scientists have developed a simple, high-throughput method for transferring isolated mitochondria and their associated mitochondrial DNA into mammalian cells. This approach enables researchers to tailor a key genetic component of cells, to study and potentially treat debilitating diseases.

Ongoing observational clinical research has identified immune system changes that persist long after initial infection with SARS-CoV-2 and may be associated with "long COVID".

Scientists have suspected mutations in a cellular cholesterol transport protein are associated with psychiatric disorders, but have found it difficult to prove this and to pinpoint how it happens. Now, scientsts have provided evidence that mice with disrupted ABCA13 protein demonstrate a hallmark behaviour of schizophrenia.
