The cerebral cortex ages less than thought

Researchers found that the primary somatosensory cortex, responsible for processing sensory information, has a layered structure that ages differently. The middle and upper layers remain stable or even thicken with age, while the lower layers show age-related degeneration, providing evidence for neuroplasticity.

Researchers identify a potential biomarker for long COVID

A study found 65 distinct protein fragments from SARS-CoV-2 inside extracellular vesicles of patients with long COVID, but not in uninfected human cells. This could be a specific and quantifiable indicator for confirming long COVID diagnosis.

Neurodegenerative diseases: What if the key lies in the mitochondria?

Researchers have established a causal link between mitochondrial dysfunction and cognitive symptoms associated with neurodegenerative diseases. By stimulating mitochondrial activity, they observed an improvement in memory deficit symptoms in animal models. The study opens the door to considering mitochondria as a new therapeutic target.

Couples who meet online less happy in love, study shows

Researchers found that individuals who met their partners online reported lower levels of marital satisfaction and experienced love less intensely. Factors contributing to these findings include similar social backgrounds, choice overload, and prioritizing physical attractiveness over thorough selection.

Long-propagating ghost phonon polaritons enabled by selective mode excitation

Researchers create novel method to control ghost hyperbolic phonon polaritons by launching waves with specially shaped gold nano-antennas, extending travel distance from 20 micrometers to 80 micrometers. This breakthrough enables new technologies such as efficient heat management and reliable quantum information systems.

Blocking brain-liver communication may prevent deadly weight loss in cancer

Researchers discovered that disrupted brain-liver communication due to vagus nerve dysregulation leads to damage in liver metabolism and cachexia development. Targeted blocking of the right vagus nerve prevents cachexia's development, enhances chemotherapy response, and improves overall health and survival in mice.

Topological pumping of light governed by Fibonacci numbers

Researchers discovered topological properties persist in quasi-periodically modulated optical lattices, governed by Fibonacci numbers. The team proposed approximating true quasi-periodic lattices with periodic sequences, leading to the discovery of Fibonacci-derived Chern numbers that dictate beam transport velocity.

North Atlantic faces more hurricane clusters as climate warms

A recent study published in Nature Climate Change confirms that tropical cyclone clusters are becoming more frequent in the North Atlantic due to climate warming. The research found that a La-Nina-like global warming pattern is shifting the hotspot for tropical cyclone clusters from the Northwestern Pacific to the North Atlantic basin.

Debris slide risk doesn’t always rise after a wildfire, study finds

A study from the University of Oregon found that debris flows and rockfall have been occurring in steep, rocky watersheds for thousands of years, regardless of fire. The researchers suggest that fire plays a relatively small role in triggering these events, highlighting the importance of considering geological history.
