Human population and consumption have surpassed Earth’s limits, increasing risks to climate and global stability. The Earth is already operating beyond its capacity to sustainably support the global population, according to new research highlighting growing strain on food systems, climate stability, and human well-being. Despite this, researchers say that slowing population growth and increasing [...]
A newly identified molecular mechanism reveals how neurons weigh survival against repair after injury. Scientists at the Icahn School of Medicine at Mount Sinai have identified a molecular switch in neurons that limits the regrowth of damaged axons. Their study, published in Nature, suggests that blocking a protein known as the aryl hydrocarbon receptor (AHR) could [...]
A new study raises important questions about widely used NAD+ supplements, suggesting that compounds often taken to boost energy and support healthy aging may have unintended consequences in cancer treatment. Millions of Americans take supplements like nicotinamide mononucleotide (NMN), nicotinamide riboside (NR), and nicotinamide (NAM) with the goal of boosting energy and supporting healthy [...]
Cancer cells may be exploiting a common antioxidant as fuel, revealing a potential weakness that future therapies could target. Cancer cells may be tapping into an unexpected energy source: an antioxidant long associated with protecting healthy cells. Researchers have discovered that tumors appear to be “addicted” to glutathione, a molecule widely known for preventing [...]
Cells are not isolated units; they continuously exchange proteins, genetic material, and even entire organelles with their neighbors. Intercellular transfer influences how tissues develop, respond to stress, and repair damage. In certain cancers, for example, tumor cells can acquire mitochondria from nearby cells to sustain growth; similar exchanges are also linked to aging processes. [...]
The chief executive of America’s largest public hospital system says he is prepared to start replacing radiologists with artificial intelligence in some circumstances, once the regulatory landscape catches up. Mitchell H. Katz, MD, president and CEO of NYC Health + Hospitals, recently spoke during a panel discussion held by Crain’s New York Business. The [...]

People with long COVID are at increased risk of developing cardiovascular disease, according to a new study from Karolinska Institutet published in eClinicalMedicine. The results show that the risk of conditions such as cardiac arrhythmias and coronary artery disease is higher even among those who were not hospitalized during the acute infection. Long COVID has [...]
Online and on social media, reports are piling up about a new Sars-Cov-2 variant that is currently on the rise: BA.3.2, also known as Cicada. That's what it's all about: The Omicron variant BA.3.2, which is currently the focus of attention, has been circulating since 2024 and is being closely monitored because of many [...]
A single blood marker may quietly signal dementia risk decades in advance. Scientists at the University of California, San Diego, have identified a blood signal that could forecast dementia risk decades before symptoms begin. Their study, recently published in JAMA Network Open, highlights a protein called phosphorylated tau 217 (p-tau217), which reflects early changes in the [...]
