French scientists have found that an imbalance in the gut bacterial community can cause a reduction in some metabolites, resulting in depressive-like behaviours. [ + ]

The grant will enable a major upgrade to the Murchison Widefield Array, giving the giant radio telescope the power to read and process signals captured from distant outer space. [ + ]

A new insulin molecule should make blood sugar regulation both easier and safer for those with type 1 diabetes, ensuring they receive just the right amount of insulin. [ + ]

Researchers have found new forms of tau protein that become abnormal in the very early stages of Alzheimer's disease before cognitive problems develop. [ + ]

Scientists have confirmed the presence in meteorites of a key organic molecule that may have been used to build other organic molecules, including some used by life. [ + ]

Restoration of vision in blind people is on the verge of becoming reality, with high-resolution implants making it possible to recognise artificially induced shapes and percepts. [ + ]

The global competition encouraged participants to build world-class data science techniques that accelerate novel COVID-19 research and drive smart and safe decision-making. [ + ]

The RFRP neurons — a population of nerve cells near the base of the brain — become active in stressful situations and then suppress the reproductive system. [ + ]

Using machine learning, researchers have identified distinct patterns of coordinated activity between different parts of the brain in people with major depressive disorder. [ + ]

A new method allows researchers to turn off CRISPR-Cas9 gene editing until it reaches key cell cycle phases where more accurate repairs are likely to happen. [ + ]

Mathematical modelling shows that continents remain weak and prone to destruction in their infancy, then progressively melt and differentiate to become stable continents. [ + ]

The hub is set to elevate local genomics research and clinical trials to a global scale by establishing three core platforms in clinical genomics, bioinformatics and health economics. [ + ]

Professor Mark Febbraio won the award for leading the development of a potential new treatment for obesity, type 2 diabetes and muscle mass loss. [ + ]

Researchers have detected a connection between Brachyspira, a genus of bacteria in the intestines, and irritable bowel syndrome (IBS) — especially the form that causes diarrhoea. [ + ]

The antiviral drug remdesivir is not recommended for patients admitted to hospital with COVID-19, regardless of how severely ill they are. [ + ]
