In a groundbreaking study, scientists have discovered a way to manipulate the very fabric of life by using light to reshape DNA strands. This innovative approach provides new insights into the material properties of chromosomes, unlocking potential advancements in understanding gene expression and developing treatments for genetic diseases.

Chromatin, the material that makes up chromosomes, is a complex structure where long strands of DNA are wrapped tightly around proteins. Despite its compact nature, chromatin must unfurl in certain regions to allow cells to access and replicate genetic information.

Some areas remain rigid and coiled, silencing genes, while others are flexible and accessible, facilitating gene expression. This duality has led scientists to question whether chromatin behaves like a solid, a liquid, or a hybrid of both.

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.

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.

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?

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.

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.

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.

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.
