Researchers have found two new mammogram-based measures for breast cancer risk, which could improve the screening process and make it less stressful for women. [ + ]

Tokyo researcher Kaori Sugihara has shown that sterilised N95 masks can be returned to use after being recharged using a van de Graaff generator. [ + ]

Researchers have developed a fully automated, low-cost and rapid microrobotic diagnostic system with comparable sensitivity to clinical detection methods. [ + ]

Researchers have made an unexpected discovery about the protein actin — one that will spark efforts to produce new tailored therapies to kill cancer cells. [ + ]

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. [ + ]

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. [ + ]

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

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. [ + ]

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. [ + ]

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

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. [ + ]
