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 [...]
Researchers at the University of Queensland and Vaxxas, a medtech company, announced the development of a high-density microarray patch (HD-MAP) that can deliver a COVID-19 vaccine through the skin without the need for needles. While such minimally invasive vaccine technology is to be welcomed, the major breakthrough is the temperature stability of the vaccine. [...]
An international research team, led by scientists from the EMPA (Zurich) and the International Iberian Nanotechnology Laboratory, which has researchers from the UPV/EHU, has succeeded in building chains of quantum magnets made of nanographene that capture the essence of one of the core models of quantum magnetism. The team's results (Nature, "Observation of fractional edge excitations in [...]
Using nanopore DNA sequencing technology, researchers from TU Delft and the University of Illinois have managed to scan a single protein: by slowly moving a linearized protein through a tiny nanopore, one amino acid at the time, the researchers were able to read off electric currents that relate to the information content of the [...]
The bonding interaction amongst Influenza A and the peptide "PeB," which selectively binds the viral surface protein hemagglutinin, has been investigated using electrically controlled deoxyribonuclic acid (DNA) nanolevers in the journal Advanced Materials. PeB is conjugated to DNA strands that are bonded to complementary anchors and fixed on the electrode surface of a "switchSENSE" biochip. [...]
After a period of falling Covid-19 illness rates, the recent spread of the delta variant of SARS-CoV-2 was a major disappointment and necessitated a reexamination of some previous assumptions. This reconsideration may, at least in part, be a correction to overly optimistic views of what highly effective SARS-CoV-2 vaccines could accomplish. Some observers had [...]
Drug giant announced results on Friday Study on 775 COVID patients found pill reduced hospitalization and death rates by 89 per cent compared to patients giving a dummy pill Results of independent study were so impressive Pfizer halted it early to seek approval for its usage It wants the Food and Drug Administration to authorize [...]
UK approval for molnupiravir comes ahead of U.S. decision UK and NHS to confirm deployment plans in due course UK secured just under half a million courses last month Drug will be given to higher risk patients Approval comes as UK struggles to tame infections Nov 4 (Reuters) - Britain on Thursday became the [...]
Nanotechnology represents the future of personalised medicine, especially in treating diseases like cancer, says a top Swiss researcher in the field. What can the technology do, and how close does it come to science fiction scenarios? For some, the term “nano” conjures strange scenarios out of science fiction. But nanoscience simply refers to a [...]
Exclusive: study raises hopes that Covid-related damage to sense of smell may be more superficial than previously feared. The virus that causes Covid-19 does not infect human brain cells, according to a study published in the journal Cell. The findings will raise hopes that the damage caused by Sars-CoV-2 might be more superficial and reversible than [...]
