Buying face shields and PPE amidst COVID-19 is a challenging task, as there are many aspects that are important to consider and can be potentially overlooked. [ + ]

Scientists say they have successfully used light as a trigger to make precise cuts in genomic material rapidly, using a molecular scalpel known as CRISPR. [ + ]

A new microscope is said to generate far less noise than customary designs, and its compactness and stability make it suitable for use in hospital operating rooms. [ + ]

Recent studies have suggested new treatment approaches for Alzheimer's disease — one utilising an existing asthma drug and another targeting the gut. [ + ]

UV-C light can kill coronaviruses including SARS-Cov-2, with some researchers now working on solutions to keep consumers safe from UV-C radiation's harmful effects. [ + ]

The device serves as a physical shield to reduce the risk of exposure to pathogens for healthcare workers performing procedures on COVID-19 patients. [ + ]

Despite advances in healthcare technology, many laboratories and research centres are still relying on traditional fax machines to transmit sensitive data. [ + ]

The LIGO and Virgo observatories have detected gravitational waves caused by the collision of a black hole, accompanied by a mysterious astrophysical object. [ + ]

Scientists have identified mutations in a gene called CNOT1 that affect brain development and impair memory and learning. [ + ]

Scientists have developed a sustainable way to extract an antimicrobial compound from seeds — a compound that killed 99% of harmful bacteria in lab tests. [ + ]

A new non-invasive molecular imaging approach may help in identifying Alzheimer's disease at early stages so that treatment can begin as soon as possible. [ + ]

A nanostructure fabrication device was used to manipulate the chirality of drug molecules by controlling the direction in which a substrate is rotated within the device. [ + ]

Scientists have identified a previously unknown immune cell that plays a crucial role presenting antigens to other immune cells during respiratory virus infections. [ + ]

Cancer cells can 'turn on' error-prone DNA copy pathways to adapt to cancer treatment — the same process used by bacteria to develop antibiotic resistance. [ + ]

Metal–organic frameworks (MOFs) — technology that resembles a sponge filled with tiny magnets — are being used to help deliver cleaner air and water. [ + ]
