Scientists have developed a new method of observing chemical reactions, using nuclear magnetic resonance spectroscopy with an unusual twist: there is no magnetic field. [ + ]

Our brains are wired to retain information that relates to the context in which highly significant events occurred. This mechanism also underlies drug addiction. [ + ]

Researchers suggest that medieval methods using everyday ingredients could help solve the growing problem of antibiotic resistance. [ + ]

The new test uses a single drop of blood — collected from a simple finger prick — and results are ready in a few hours. [ + ]

The malaria drug chloroquine, demonstrated to inhibit SARS-CoV-2 infection of African green monkey kidney cells, is not able to prevent infection of human lung cells. [ + ]

The nanoparticles were engineered to only release their drug content upon a specific cue which is present in the tumour area. [ + ]

Researchers have identified brain circuitry that plays a key role in the behavioural differences that characterise autism spectrum disorder. [ + ]

The suitcase lab enables screening of millions of bacteria in a single water sample, instead of running many tests in parallel to look for different pathogens. [ + ]

Curcumin, a natural compound found in the spice turmeric, can prevent transmissible gastroenteritis virus (TGEV) from infecting cells in pigs. [ + ]

Illumina has a new addition to its portfolio: genomic compression-software company Enancio, based in Cesson-Sévigné, France. [ + ]

Researchers have designed and validated a low-cost 3D-printed device that, when connected to a smartphone, makes it possible to conduct chemical analyses. [ + ]

The shared brain areas showing structural aberrations were mainly in cortical areas associated with cognitive processing, memory and self-awareness. [ + ]

Researchers have synthesised carbon dots from human hair waste that can detect trace amounts of chloroform in water. [ + ]

Metastatic breast cancer cells can reprogram natural killer (NK) cells so that they stop killing cancer cells and instead assist in metastasis. [ + ]

Mutating the enzyme at the heart of the CRISPR gene editing system can improve its fidelity, which may prove therapeutically safer than the current system. [ + ]
