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 [...]
In what is believed to be one of the largest studies of its kind, Johns Hopkins Medicine researchers have shown that antibody levels against SARS-CoV-2 (the COVID-19 virus) stay more durable—that is, remain higher over an extended period of time—in people who were infected by the virus and then received protection from two doses [...]
People with certain health conditions that make them moderately or severely immunocompromised may get a fourth mRNA Covid-19 shot, according to updated guidelines from the US Centers for Disease Control and Prevention. The CDC authorized a third dose for certain immunocompromised people 18 and older in August. It said a third dose, rather than a booster -- [...]
Ultrashort flashes of light lasting less than a quadrillionth of a second are fast growing in technological importance. In laser sources, pairs and groups of light flashes can be created instead of individual flashes. Similar to the chemically bonded atoms in a molecule, they are coupled with each other and their short temporal intervals [...]
Compared to their bulk materials, nanomaterials offer a wide range of distinct physicochemical properties that are ideal for many biomedical purposes. Some of the different applications of nanomaterials within medicine include drug delivery, tissue engineering, bio-micromechanical systems (bioMEMS), biosensors, microfluidics, and diagnostics. Of these, nanomaterial-based drug delivery systems have emerged as one of the [...]
Using specialized carbon nanotubes, MIT engineers have designed a novel sensor that can detect SARS-CoV-2 without any antibodies, giving a result within minutes. Their new sensor is based on technology that can quickly generate rapid and accurate diagnostics, not just for Covid-19 but for future pandemics, the researchers say. “A rapid test means that [...]
