Nanocomposites are a class of nanomaterials, where one or more nanostructured materials (organic/inorganic) are incorporated in metal, polymer, or ceramic to obtain a new material with many unique properties. Nanocomposites are applied in various branches of science and different industries, such as target drug delivery, imaging, agriculture, sensors, batteries, artificial implants, and aircraft. Advancements [...]
Pfizer said it will be able to manufacture and distribute an updated version of its COVID-19 vaccine within 100 days if the new variant Omicron is found to be resistant to its current vaccine. Scientists first detected the new variant in South Africa. It has since spread to several other countries, including Israel and [...]
UK places South Africa on red travel list over B.1.1.529 variant picked up by scientists in country. What is the new variant and why is it a concern? Scientists have detected a new Covid-19 variant called B.1.1.529 and are working to understand its potential implications. About 100 confirmed cases have been identified in South Africa, [...]
The B.1.1.529 variant was first spotted in Botswana and six cases have been found in South Africa. Scientists have said a new Covid variant that carries an “extremely high number” of mutations may drive further waves of disease by evading the body’s defences. Only 10 cases in three countries have been confirmed by genomic [...]
Scientists are building a new super-resolution microscope that uses laser light to study the inner workings and behaviours of superbugs to gain new insights into how they cause disease. The microscope will allow scientists to peer into bacteria like Streptococcus Pneumoniae at a molecular-scale resolution – showing up objects smaller than 10,000th the thickness of a [...]
Cells can produce unique electrical signals. These signals can be linked to various cancers, such as the breast, lung, liver, brain, pancreas and prostate cancers, meaning that they can be used as indicators for early cancer diagnosis. Thus, using electrical signals as indicators and targets for cancer treatments could potentially improve the outcome for [...]
Conventional microscopes produce enlarged images of small structures or objects with the help of light. Nanoparticles, however, are so small that they hardly absorb or scatter light and, hence, remain invisible. Optical resonators increase the interaction between light and nanoparticles: They capture light in smallest space by reflecting it thousands of times between two [...]
From a new article By Dhruv Khullar in the New York Times: New antiviral drugs are startlingly effective against the coronavirus—if they’re taken in time. n March, 2020, researchers at Emory University published a paper about a molecule called NHC/EIDD-2801. At the time, there were no treatments available for the coronavirus. But NHC/EIDD-2801, the researchers wrote, possessed [...]
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. [...]
