Not in leading research but interesting.

According to a new study, a polyphenol-rich natural extract positively impacts lifespan, healthspan, and cellular senescence. These results were observed in both cell culture and a mouse model [1].

Traditional and folk medicines offer many botanical extracts that can be tested by modern science for their medicinal properties and influences on aging. One such plant is the Bolivian prawn sage (Salvia haenkei).

An ischemic stroke is a type of stroke that occurs when a blood clot in an artery, also known as thrombus, or the progressive narrowing of arteries, blocks the blood and oxygen flowing to the brain. This process can cause both temporary and permanent brain damage, for instance, leading to partial paralysis, cognitive impairments and other debilitating impairments.

Statistics suggest that older age increases the risk of experiencing ischemic strokes. While neuroscience studies have shed light on many of the physiological processes underpinning strokes, the immune responses following these events and promoting recovery remain poorly understood.

Researchers at the Institut Blood and Brain @ Caen-Normandie (BB@C), University of Edinburgh and other institutes in Europe carried out a study exploring how central nervous system (CNS)-associated macrophages (CAMs), immune cells residing at the CNS interfaces, contribute to post-stroke immune responses.

The 2024 Kavli Prize in Nanoscience is awarded to three nanomedicine pioneers who laid the foundation of controlled release, biomedical imaging and diagnostics.

Scientists have sequenced the largest known animal genome — and it’s 30 times bigger than the human genome.

The genome belongs to the South American lungfish (Lepidosiren paradoxa), a primeval, air-breathing fish that “hops” onto land from the water using weird, limb-like fins. The fish’s DNA code expanded dramatically over the past 100 million years of evolutionary history, racking up the equivalent of one human genome every 10 million years, researchers found.

During the Cold War Era of the 1960s, Russian researchers were looking for ways to support the immune system in conditions running the gamut from cancer to bio-warfare agents. Eastern Europeans, with a cultural love of fermented milk products, logically looked to probiotics, or lactobacillus, for immune support because it was safe, cheap and effective.

A Bulgarian researcher and medical doctor, Dr. Ivan Bogdanov, researched lactobacillus bacteria in the 1960s. Bogdanov believed that specific strains of probiotics could have anti-tumor properties.

The doctor’s research team injected mice with a sarcoma cancer, then administered a crude mixture of cell fragments from a strain of Lactobacillus delbrukii. Bogdanov observed that the cancer disappeared within a few days. Subsequently, researchers attempted to re-grow cancer in the same mice, but without success — the mice seemed immune to the cancer cells.

Researchers have developed a new two-photon fluorescence microscope that captures high-speed images of neural activity at cellular resolution. By imaging much faster and with less harm to brain tissue than traditional two-photon microscopy, the new approach could provide a clearer view of how neurons communicate in real time, leading to new insights into brain function and neurological diseases.

Scientists have made a groundbreaking advancement in understanding light propagation through complex media, potentially revolutionizing fields like optical communication and medical imaging.

By introducing the concept of coherence entropy, a new metric for evaluating light behavior, they have provided a reliable tool for managing light fields in challenging environments. This research could significantly enhance the performance of systems that rely on light, particularly in situations where traditional methods fail due to media distortion.

Light technology is at the heart of many cutting-edge innovations, from high-speed internet to advanced medical imaging. However, transmitting light through challenging environments, such as turbulent atmospheres or deformed optical systems, has always posed a significant hurdle. These complexities can distort and disrupt the light field, making it difficult to achieve clear and reliable results. Scientists have long sought ways to overcome these limitations, and a new breakthrough may hold the key to advance practical applications.
