A revolutionary nanomaterial with huge potential to tackle multiple global challenges could be developed further without acute risk to human health, research suggests. The study is published in the journal Nature Nanotechnology. Carefully controlled inhalation of a specific type of graphene—the world's thinnest, super strong and super flexible material—has no short-term adverse effects on lung or cardiovascular function, [...]

Neurological symptoms are apparently not a result of SARS-CoV-2 infection of the brain. Scientists still are not sure how neurological symptoms arise in COVID-19. Is it because SARS-CoV-2 infects the brain? Or are these symptoms the result of inflammation in the rest of the body? A study by Charité – Universitätsmedizin Berlin has now produced evidence to [...]

We’ve all been more aware of lung health since Covid-19. However, for people with asthma and chronic obstructive pulmonary disease (COPD), dealing with lung problems is a lifelong struggle. Those with COPD suffer from highly inflamed lung tissue that swells and obstructs airways, making it hard to breathe. The disease is common, with more [...]

A multidisciplinary research team at Vanderbilt University and Vanderbilt University Medical Center has discovered a new way to kill a tumor by disrupting its acidic "microenvironment" without harming normal tissue. The target of this unorthodox approach is hydroxyapatite (HAP), a naturally occurring mineral that is a major component of bone and teeth but is [...]

Understanding the ancestry of virus families may assist researchers in pinpointing which variants possess the potential to become Disease X, the elusive pathogen responsible for the next worldwide pandemic. A study has identified 70 virus lineages – groups of related viruses – that pose the biggest risk. Viruses from other genetic backgrounds are unlikely to cause [...]

Cornell University researchers have created a new version of a microbe to compete economically with E. coli—a bacteria commonly used as a research tool due to its ability to synthesize proteins—to conduct low-cost and scalable synthetic biological experiments. As an inexpensive multiplier—much like having a photocopier in a test tube—the bacteria Vibrio natriegens could help [...]

Highlighting the absence of evidence for the controllability of AI, Dr. Yampolskiy warns of the existential risks involved and advocates for a cautious approach to AI development, with a focus on safety and risk minimization. There is no current evidence that AI can be controlled safely, according to an extensive review, and without proof [...]

An interdisciplinary team of Cornell researchers has identified an innovative way to harness the antioxidant and antibacterial properties of the botanical compound lawsone to make nanofiber-coated cotton bandages that fight infection and help wounds heal more quickly. Their findings, published in the International Journal of Pharmaceutics, are especially important given the increasing prevalence of multidrug-resistant bacteria. Cotton [...]

Researchers from the Netherlands Institute for Neuroscience found that the superior colliculus, a brain region preserved throughout evolution, plays a more vital role in vision than previously believed. When we look at something, we can easily distinguish an object from the background. While this sounds obvious, how our brain accomplishes it is still quite [...]

Stefan Wilhelm, an associate professor in the Stephenson School of Biomedical Engineering at the University of Oklahoma, and several students in his Biomedical Nano-Engineering Lab have recently published an article in the journal Nano Letters that outlines their recent important nanomedicine advancement. The group examined how to create tools that produce nanomedicines, such as vaccine formulations, directly at the [...]
