A University of Maryland researcher and colleagues found that the fungus Metarhizium robertsii removes mercury from the soil around plant roots, and from fresh and saltwater. The researchers also genetically engineered the fungus to amplify its mercury detoxifying effects.
Mercury pollution of soil and water is a worldwide threat to public health. This new work suggests Metarhizium could provide an inexpensive and efficient way to protect crops grown in polluted areas and remediate mercury-laden waterways.
The study, which was conducted by UMD professor of entomology Raymond St. Leger and researchers in the laboratory of his former post-doctoral fellow, Weiguo Fang (now at Zhejiang University in Hangzhou, China), was published in Proceedings of the National Academy of Sciences (PNAS) on November 14, 2022.
A new study by investigators from Brigham and Women’s Hospital, a founding member of the Mass General Brigham health care system, demonstrated that shingles, also known as herpes zoster, is associated with an almost 30% higher long-term risk of a major cardiovascular event such a stroke or heart attack. Their results are published in the Journal of the American Heart Association.
“Our findings suggest there are long-term implications of shingles and highlight the importance of public health efforts for prevention,” said lead author Sharon Curhan, MD, ScM, a physician and epidemiologist in the Channing Division of Network Medicine at Brigham and Women’s Hospital.
“Given the growing number of Americans at risk for this painful and often disabling disease and the availability of an effective vaccine, shingles vaccination could provide a valuable opportunity to reduce the burden of shingles and reduce the risk of subsequent cardiovascular complications.”
A seven-year study reveals that variations in specific isotopes linked to magmatic ‘foams’ can be used to predict volcanic unrest.
Scientists have found a way to use the ratio of atoms in specific gases created by volcanic fumaroles (gaps in the Earth’s surface) to detect what’s happening to magma deep below.
Volcanic eruptions are dangerous and challenging to predict. Could the new findings change this?

Much like obtaining a blood test to examine your health, the new method, published in Nature by a team at the University of Tokyo, could indicate when things are “heating up.” Significantly, it could aid in the prediction of future volcanic eruptions.
Studies have shown poor balance can be associated with serious health problems – as well as increased risks of falls as we get older. But there are ways to make yours better.
AI can also be of benefit in the diagnosis and treatment of patients. Tools have been created that help diagnose a patient as well as a human would.
AI isn’t a new technology—it’s been researched and developed since the 1950s and is currently present in many of our daily routines. Most of these applications are so common that we don’t even notice them.
Our lives often depend on the healthcare industry. So, having a technology that allows you to speed up patient registration processes and help diagnose more quickly and effectively is essential. Every health center should consider the use of AI for the benefit of its processes so it can adapt to the modern world and its accelerated pace.
MUSC Hollings Cancer Center researcher Ashish Deshmukh, Ph.D., has identified a dramatic recent rise in cervical cancer incidence among women in their early 30s. This work was published Nov. 21 in the Journal of the American Medical Association (JAMA).
Cervical cancer is mostly related to human papillomavirus (HPV), and screening has made this cancer preventable. Yet, it is estimated that over 14,000 new cases will be diagnosed this year and more than 4,000 deaths will be attributed to cervical cancer.
“HPV is a group of over 200 viruses. At least 14 high-risk HPV types can cause several types of cancers, including cervical, anal and head and neck cancers. In the era of the overall decline in cancer incidence, cancers caused by HPV are unfortunately rising,” said Deshmukh, an associate professor in the Department of Public Health Sciences at MUSC.
Triple threat. Tripledemic. A viral perfect storm. These frightening phrases have dominated recent headlines as some health officials, clinicians, and scientists forecast that SARS-CoV-2, influenza, and respiratory syncytial virus (RSV) could surge at the same time in Northern Hemisphere locales that have relaxed masking, social distancing, and other COVID-19 precautions.
But a growing body of epidemiological and laboratory evidence offers some reassurance: SARS-CoV-2 and other respiratory viruses often “interfere” with each other. Although waves of each virus may stress emergency rooms and intensive care units, the small clique of researchers who study these viral collisions say there is little chance the trio will peak together and collectively crash hospital systems the way COVID-19 did at the pandemic’s start.
“Flu and other respiratory viruses and SARS-CoV-2 just don’t get along very well together,” says virologist Richard Webby, an influenza researcher at St. Jude Children’s Research Hospital. “It’s unlikely that they will circulate widely at the same time.”
UNSW researchers have overcome a major design challenge on the path to controlling the dimensions of so-called DNA nanobots—structures that assemble themselves from DNA components.
Self-assembling nanorobots may sound like science fiction, but new research in DNA nanotechnology has brought them a step closer to reality. Future nanobot use cases won’t just play out on the tiny scale, but include larger applications in the health and medical field, such as wound healing and unclogging of arteries.
Researchers from UNSW, with colleagues in the UK, have published a new design theory in ACS Nano on how to control the length of self-assembling nanobots in the absence of a mould, or template.
Spiraling costs, closed facilities, capacity issues, staff burnout, staff shortages, lots of chaos — sounds like an ailing industry — and that industry is healthcare. Can artificial intelligence help mend some of the problems faced by hospitals and healthcare providers? There has been progress on that front — not fast enough, but progress nonetheless.
While interest in healthcare AI is high, “the level of acculturation of C-level executives is lagging, especially for organizations that would need it the most — pharmas, medtechs and hospitals,” a recent Capgemini report relates. The problem, the study’s authors relate, is data. “Enhancing the patient care pathway and improving care delivery remain on the top of the organizations’ agendas,” according to the report’s team of coauthors, led by Charlotte Pierron-Perlès. However, only about a third of healthcare organizations surveyed by Capgemini prioritize the availability of patient information. “We do not see major progress from 2021 [the year of the previous study].”
The good news is that many healthcare providers are stepping up their AI work. “The healthcare industry is now starting to implement AI and machine learning solutions at increased scale and sophistication,” says Tony Ambrozie, CIO at Baptist Health South Florida. “AI and machine learning will augment their ability to make sense of the vast amounts of data available.”
The fourth discussion of the NEW NOW program, “Transhumanism: Beyond the Human Frontier?”, took place on December 16.
Together with our guest experts, we tried to identify the latest technology that has either already become a reality or is currently in development, focusing on the ethical aspects of the consequences that ensue. We reflected on the question of whether the realization of transhumanist ideas is likely to entail a radical change in the ways people relate to one another. How far are we prepared to go in changing our bodies in order to attain these enhanced capacities? We will attempt to identify the “human frontier”, beyond which the era of posthumanism awaits.
