Vanderbilt University Medical Center-led research reveals subtle changes in the visual pathways of individuals with chronic mild traumatic brain injury (TBI), even when standard eye examinations show no abnormalities. These findings include structural and functional deficits despite participants showing normal visual acuity during clinical examination.

Mild TBI accounts for approximately 3 million cases in the U.S. each year. Up to 85% of TBI patients, regardless of injury severity, report such as , blurred vision, or difficulty reading. Persistent symptoms including memory problems, irritability, or slowed thinking often impact quality of life. Despite these symptoms, many individuals display no abnormalities during routine clinical evaluations such as fundus examinations.

In a case-control study, “Primary Visual Pathway Changes in Individuals With Chronic Mild Traumatic Brain Injury,” published in JAMA Ophthalmology, researchers reported that 78% of participants with mild TBI exhibited visual deficits when evaluated with a comprehensive battery of tests.

In a recent study published in the journal Cell, researchers investigate the role of fibroblastic reticular cells (FRCs) in creating T-cell-supportive niches within lung cancer tumors. The study findings elucidate how these specialized cells contribute to immune defenses by forming interconnected environments that facilitate T-cell activity, potentially enhancing anti-tumor immunity in non-small cell lung cancer (NSCLC).

What are FRCs?

The ability of the immune system to fight cancer relies on coordinated interactions between various immune cells and their specialized microenvironments.

A new study reveals that metformin, a widely prescribed diabetes medication, can significantly improve health parameters in aged male cynomolgus monkeys — possibly by slowing the aging process. The findings represent an important step toward understanding how pharmaceutical interventions might, in the future, extend the healthspan and delay age-related diseases in humans.

Science and Technology: This was previously thought to be impossible:

This was previously thought to be impossible:

Scientists were astonished to find that recirculating a cocktail of preserving agents through a severed pig’s head caused the animal’s brain to show signs of life.

As New Scientist reports, basic cellular functions were restored in the dismembered brain — something that was previously thought impossible following the cessation of blood flow.

A research team headed by Prof. Karl Leo at TUD Dresden University of Technology have developed an innovative, nature-inspired solution that could revolutionize the electronics industry: “Leaftronics.” This innovative approach leverages the natural structure of leaves to create biodegradable electronic substrates with enhanced properties and offers a sustainable, efficient, and scalable solution to the global-waste problem. These findings have now been published in the journal Science Advances.

Electronic devices, from toys to smartphones, consist of circuits. Specific substrates are used to manufacture these circuits. In commercial electronics, these are printed circuit boards (PCBs) made of glass fiber-reinforced epoxy resin.

Most of these materials are not recyclable, let alone biodegradable. Given the sheer volume of electronic waste of more than 60 million tons per year (of which over 75% is not collected worldwide), there is an urgent need for sustainable alternatives.
