'This is something that's never been observed before'. A team of scientists from the University of Vermont (UVM) has discovered a new form of reproduction in computer-designed organisms (CDOs) that they had created earlier. In this new form of replication, these robots ingest single-cell organisms and release "babies" that look and move like them, [...]
Harnessing renewable energy has been a prominent strategy to promote environmental conservation. Butterfly wings exhibit many unique properties, such as their striking wing coloration, light absorption mechanisms, and responses to various stimuli. For many years researchers have tried to replicate the intricate features of nature to develop artificial functional materials such as sensors, robotics, [...]
Brigham and Women's Hospital in Boston Massachusetts will soon begin Phase I trials of a nasal vaccine designed to prevent or slow the progression of Alzheimer's disease (AD), a press release said. This is the first occasion when a nasal vaccine is being attempted for the disease, which affects more than six million people in the U.S. [...]
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 [...]
