Every week, a group of epidemiologists across the north-east of the United States joins a Zoom call entirely devoted to discussing the latest hints of new Covid-19 variants being reported around the world. “It’s like the weather report,” says William Hanage, an epidemiologist at the Harvard TH Chan School of Public Health. “It used to be, [...]
To grow and spread, cancer cells must evade the immune system. Investigators from Brigham and Women's Hospital and MIT used the power of nanotechnology to discover a new way that cancer can disarm its would-be cellular attackers by extending out nanoscale tentacles that can reach into an immune cell and pull out its powerpack. [...]

A new 3D printing technology makes the production of complex metallic objects at the nanoscale possible. A team of chemists led by a scientist from the University of Oldenburg has developed an electrochemical technique that can be used to make objects out of copper just 25 nanometres in diameter. The new technique is based [...]
The creation of nanoscale computers for use in precision health care has long been a dream of many scientists and health care providers. Now, for the first time, researchers at Penn State have produced a nanocomputing agent that can control the function of a particular protein that is involved in cell movement and cancer [...]
Liposomes may be the unsung heroes of the COVID-19 pandemic. Without the protection of these microscopic vesicles, the delicate strands of messenger RNA (mRNA) that lie at the heart of the Pfizer and Moderna COVID-19 vaccines would be quickly destroyed by enzymes in the body, making it nearly impossible for their genetic instructions to [...]
London: Drugmaker Pfizer has signed a deal with a UN-backed group to allow other manufacturers to make its experimental COVID-19 pill, a move that could make the treatment available to more than half of the world’s population. Pfizer also asked the US Food and Drug Administration to authorise the pill in the US. In a [...]
Exclusive: Oxfordshire-based Emergex gets go-ahead for trials in Switzerland for skin patch vaccine. An Oxfordshire-based company will soon start clinical trials of a second-generation vaccine against Covid-19, an easy-to-administer skin patch that uses T-cells to kill infected cells and could offer longer-lasting immunity than current vaccines. Emergex was set up in Abingdon in 2016 [...]
New research published in the bioRxiv* preprint server suggests a small cationic peptide known as crotamine may inhibit the replication and transcription of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Crotamine in the D-enantiomer form successfully inhibited SARS-CoV-2 replication by targeting the C30 Endopeptidase (3CLpro protease). Crotamine is found in rattlesnake Crotalus durissus terrificus venom and has analgesic, [...]
A team of researchers at the Swiss Federal Institute of Technology has developed a high-performance Scanning Ion Conductance Microscope (SICM) using the latest advances in nanopositioning, nanopore fabrication, microelectronics and controls engineering. Time-resolved scanning allows the 3D visualization of dynamic structures in a eukaryotic cell membrane at nanometer resolutions. Studying the functions of living cells and [...]
