Smart Liquid Crystal Lenses Filter Out Seizure-Inducing Light for Epilepsy Patients

Revolutionary glasses have been engineered to shield individuals from seizure-inducing light, offering a potential new layer of safety for epilepsy patients during daily tasks and entertainment.

People with photosensitive epilepsy may soon benefit from an innovative pair of glasses designed to block light wavelengths known to trigger seizures.

Researchers from the University of Glasgow and the University of Birmingham have developed a prototype liquid crystal lens that could help reduce the risk of seizures. Their findings, published in Cell Reports Physical Science, highlight the potential of this technology to improve the lives of those with photosensitive epilepsy.

MIT Scientists Harness Light To Wirelessly Monitor Cellular Electrical Signals

Integrated into a high-resolution wireless biosensing device, the antennas could enable researchers to decode complex electrical signals generated by cells.

Monitoring electrical signals in biological systems allows scientists to study how cells communicate, providing valuable insights that can improve the diagnosis and treatment of conditions such as arrhythmia and Alzheimer’s disease.

But devices that record electrical signals in cell cultures and other liquid environments often use wires to connect each electrode on the device to its respective amplifier. Because only so many wires can be connected to the device, this restricts the number of recording sites, limiting the information that can be collected from cells.

Does substance use change the brain’s structure, or does brain structure predispose some to substance use?

A study led by researchers from the Indiana University School of Medicine, Washington University in St. Louis, and other institutions has identified neuroanatomical differences in children associated with early substance use initiation.

Early-age substance use is strongly associated with a heightened risk for (SUDs) and other adverse outcomes later in life. Neuroanatomical changes in brain structure have been linked to substance use, especially in youth when the brain is undergoing substantial development.

But are the changes seen in substance user brains primarily a result of the substance use itself, or is it an inherent predisposition in some individuals with certain neuroanatomical variations?

Dog drug may help humans slow aging, extend life, scientists explore

Not a dramatic increase, but a good one.

Loyal, a US biotech startup, has been conducting research and development on LOY-002, a potential drug for extending the lifespan of dogs.

The Guardian reported that the company expects to launch this beef-flavored pill on the market early next year.

Interestingly, Loyal believes their research on canine longevity will also benefit humans.

WHO declares new COVID outbreak in China global health emergency

The World Health Organization, WHO, has declared the outbreak of a new coronavirus in China, a global health emergency.

The WHO Director-General Tedros Ghebreyesus made the announcement at a press conference in Geneva.

WHO’s emergency committee on the epidemic had reportedly met Thursday afternoon and recommended designating the outbreak a Public Health Emergency of International Concern, PHEIC.

For first time, DNA tech stores, rewrites data and even solves sudoku

Forget conventional electronics, DNA tech stores data, offers computing functions.

Called “primordial DNA store and compute engine,” the technology could store data securely for thousands of years in commercially available spaces without degrading the information-storing DNA, suggests testing.

In conventional computing technologies, the ways data are stored and processed are compatible with each other, according to researchers. However, in reality, data storage and data processing are done in separate parts of the computer, and modern computers are a network of complex technologies.

The new technology is made possible by using recent developments, which have enabled the creation of soft polymer materials that have unique morphologies.

Efferocytosis: The Janus‐Faced Gatekeeper of Aging and Tumor Fate

The multistep process by which phagocytes engulf these deceased cells without eliciting an inflammatory response is called efferocytosis. Despite significant insights into the fundamental mechanisms of efferocytosis, its implications in disorders such as aging and cancer remain elusive. Upon summarizing and analyzing existing studies on efferocytosis, it becomes evident that efferocytosis is our friend in resolving inflammation, yet it transforms into our foe by facilitating tumor development and metastasis. This review illuminates recent discoveries regarding the emerging mechanisms of efferocytosis in clearing apoptotic cells, explores its connections with aging, examines its influence on tumor development and metastasis, and identifies the regulatory factors of efferocytosis within the tumor microenvironment. A comprehensive understanding of these efferocytosis facets offers insights into crucial physiological and pathophysiological processes, paving the way for innovative therapeutic approaches to combat aging and cancer.

A Key Brain Difference Linked to Autism Is Found for the First Time in Living People

A key brain difference linked to autism has been found for the first time in living people.

Using a sophisticated imaging technology, Yale School of Medicine researchers found that the brains of autistic adults have fewer synapses — crucial junctions between nerve cells and other cells — than the brains of neurotypical individuals: bit.ly/3NK9gGQ Yale.

Autistic brains have fewer synapses compared to neurotypical brains, PET scans show.
