A study published by The BMJ sheds light on the risk of infection with SARS-CoV-2 and covid-19 outcomes among adults living with and without children during the first two waves of the UK pandemic. It finds no evidence of any increased risk in wave 1 (Feb to Aug 2020). Small increased risks of infection and hospital admission were seen in wave 2 (Sept to Dec 2020), but this did not translate into…
Electricity may slow – and in some cases, stop – the speed at which breast cancer cells spread through the body, a new study indicates. The research also found that electromagnetic fields might hinder the amount of breast cancer cells that spread. The findings, published recently in the journal Bioelectricity, suggest that electromagnetic fields might be a useful tool in fighting cancers that…

In what is believed to be the first published study of Covid-19 vaccine effectiveness in long-term care facilities such as nursing homes, a research team co-led by the Yale School of Public Health found a widely used vaccine is highly successful in preventing infections. Residents of such facilities, particularly those in skilled nursing facilities (SNFs), have experienced disproportionately high…
Do BMMFs, the novel infectious agents found in dairy products and bovine sera, play a role in the development of colorectal cancer? Scientists led by Harald zur Hausen detected the pathogens in colorectal cancer patients in close proximity to tumors. The researchers show that the BMMFs trigger local chronic inflammation, which can cause mutations via activated oxygen molecules and thus promote…
During pandemics, protective behaviors need to be motivated by effective communication. A critical factor in understanding a population’s response to such a threat is the fear it elicits, since fear both contributes to motivating protective responses, but can also lead to panic-driven behaviors. Furthermore, lockdown measures affect well-being, making it important to identify protective factors…
It is possible to identify Parkinson’s Disease based on compounds found on the surface of skin, according to new research. The findings offer hope that a pioneering new test could be developed to diagnose the degenerative condition through a simple and painless skin swab. Scientists at The University of Manchester have developed a technique which works by analysing compounds found in sebum -…
The highly infectious variant of Covid-19 discovered in Kent, which swept across the UK last year before spreading worldwide, is between 30 and 100 per cent more deadly than previous strains, new analysis has shown. A pivotal study, by epidemiologists from the Universities of Exeter and Bristol, has shown that the SARS-CoV-2 variant, B.1.1.7, is associated with a significantly higher mortality…
More human twins are being born than ever before, according to the first comprehensive, global overview published in Human Reproduction, one of the world’s leading reproductive medicine journals. Since the 1980s the twinning rate has increased by a third from 9 to 12 per 1000 deliveries, meaning that about 1.6 million twins are born each year worldwide and one in every 42 children born is a…
Despite Brexit uncertainties, four leading UK cancer research experts expressed optimism for continued pan-European collaboration and innovation during the online panel debate ‘Brexit deal: What it really means for cancer research and innovation’ hosted by the National Cancer Research Institute (NCRI).
Smart speakers, such as Amazon Echo and Google Home, have proven adept at monitoring certain health care issues at home. For example, researchers at the University of Washington have shown that these devices can detect cardiac arrests or monitor babies breathing. But what about tracking something even smaller: the minute motion of individual heartbeats in a person sitting in front of a smart…
When airborne pollen levels are higher, increased SARS-CoV-2 infection rates can be observed. These results were determined by a large-scale study conducted by an international team headed by researchers at the Technical University of Munich (TUM) and the Helmholtz Zentrum München. Members of high-risk groups could protect themselves by watching pollen forecasts and wearing dust filter masks.
Using a nanopore, researchers have demonstrated the potential to reduce the time required for sequencing a glycosaminoglycan — a class of long chain-linked sugar molecules as important to our biology as DNA — from years to minutes. Research to be published this week in the Proceedings of the National Academies of Sciences shows that machine-learning and image recognition software could be…
It is called the "survival protein" because it plays a central role in the growth of cancer cells: survivin influences two important processes in the body's cells at the same time – cell death and cell division. Chemists and biologists at the Universität Duisburg-Essen (UDE) have now succeeded in developing a precise molecule that can bind the protein’s surface at a defined site…
