The World Health Organization (WHO) has added another COVID strain to its list of coronavirus variants to keep an eye on: the COVID-19 Lambda variant.
At this point, as is the case with other variants such as the Delta variant, it’s too early to know whether the Lambda could be more deadly than other strains or whether it’s resistant to vaccines or treatments.
An increase in transmissibility doesn’t necessarily mean that a variant is more deadly. Take the case of Pfizer/BioNTech’s COVID vaccine, which may only be about 64% effective in preventing the Delta variant’s spread or minor COVID symptoms but is still more than 90% effective in preventing serious illness or hospitalization, according to new research out of Israel.
There is no proof that spike proteins created in response to mRNA vaccines are harmful to the body, scientists have told Reuters. The claim was made by immunologist Byram Bridle (here) in an interview [...]
Scientists have worked out how to best get DNA to communicate with membranes in our body, paving the way for the creation of ‘mini biological computers’ in droplets that have potential uses in biosensing [...]
Reactive oxygen species (ROS) exhibit the potential to act as signal carriers during the development of malignant tumors. At a suitable concentration, ROS tends to mediate cell growth and signal transduction. But ROS are [...]
One of the biggest challenges when it comes to probing and manipulating the brain are the blunt tools we have at our disposal. But breakthroughs in nanotechnology could soon change that, say researchers. Neuroscience has [...]
When liquid meets gas, a unique zone forms. Variable by nature, molecules can cross from one state to another, combining in unique ways to either desirable or unwanted ends. From heat escaping a mug [...]
A newly detected coronavirus variant is on the rise in England, with the virus believed to be an offshoot of Delta. According to a briefing from the UK Health Security Agency, released on Friday, [...]
A team of researchers has developed a new nanomechanical technique for fast, one-step, immune-affinity tests, which can quantify the immune response induced by different COVID-19 variants in serum. Their technique provides a new tool [...]
Lawrence Livermore National Laboratory (LLNL) scientists have developed a new method for 3D printing living microbes in controlled patterns, expanding the potential for using engineered bacteria to recover rare-earth metals, clean wastewater, detect uranium, [...]
Nanomedicines may offer clinicians a way to deliver precise, targeted therapy directly to tumors without damaging surrounding tissue. Yet, progress in the development of new drugs that treat cancer at the nanoparticle level has [...]
Cambridge researchers have discovered how T cells—an important component of our immune system—are able keep on killing as they hunt down and kill cancer cells, repeatedly reloading their toxic weapons. Cytotoxic T [...]
Sunday, October 3, set records for the most COVID-19 deaths in Russia on a single day. Only 29% of people in Russia are vaccinated, despite the country being the first to approve a vaccine. [...]
New research from the University of Technology Sydney (UTS) has found that pathogens that form biofilms can evolve to survive nanosilver treatment. The study is the first to demonstrate that long-term nanosilver treatment can [...]
New variants of SARS-CoV-2 are more virulent and transmissible than the original variant of the virus. Health experts associate these variants of concern (VOCs) with increased risk of hospitalization, intensive care unit (ICU) admission, [...]
Freeze-dried genetic circuits could reveal the presence of SARS-CoV-2, Ebola, MRSA, and more. Masks and testing have been key to the COVID-19 pandemic response—and now devices that combine the two may be on the [...]
