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 [...]
Nanotechnology is revolutionizing everything from industry to medicine. We live in the most scientifically advanced age of all time, while simultaneously living in a profoundly scientifically-illiterate era, especially in the United States. People used to believe the sun was driven around the Earth by some god in a chariot, but considering what genuine scientific knowledge [...]
Study says some individuals clear virus rapidly due to a strong immune response from existing T-cells, meaning tests record negative result. We all know that person who, despite their entire household catching Covid-19, has never tested positive for the disease. Now scientists have found an explanation, showing that a proportion of people experience “abortive [...]
The coronavirus disease 2019 (COVID-19) pandemic has caused several waves of infections in many world regions, so strong as to overwhelm local healthcare services. In this new situation, faced with an unknown virus, the need is to produce clinical guidelines that help recognize and manage critical COVID-19. Meanwhile, conditions such as chronic obstructive pulmonary [...]
