Synaptic Pruning: How Viruses Might Hijack Your Brain’s Cleanup Crew
The brain maintains efficiency by deleting unused connections, but viruses can disrupt this critical maintenance. A review suggests pathogens trigger inflammation that leads to either excessive clearing or cluttered neural pathways.
Global Analysis

Evolution, Engineering, and the Future of Biodegradable Sensors
Researchers have developed a wireless, biodegradable implant capable of monitoring deep-tissue physiology from up to 16cm away. Validated in horses, the device utilises a unique folded structure to maintain signal integrity without batteries or permanent hardware.

Zebrafish Head Direction Cells Reveal Ancient Navigation Circuits
Researchers have mapped the neural architecture allowing larval zebrafish to navigate using visual cues, pinpointing the habenula-interpeduncular nucleus pathway as the critical integration site. This study confirms that vertebrate spatial orientation functions effectively via hindbrain circuits, mirroring mechanisms found in invertebrates.

Magnetic Winds Drive Exoplanet Atmospheric Escape in Young Systems
Observations of the young planet DS Tucanae Ab reveal that stellar magnetic fields, rather than just radiation pressure, actively strip planetary atmospheres. This suggests that the evolution of Neptune-sized worlds is governed by complex star-planet magnetic interactions.

Ancient Formula Meets Modern Science in Alzheimer's Disease Treatment Research
Researchers investigated the traditional formula Tiaobu Xinshen Recipe (TXR) in mice bred to mimic dementia. The study found that TXR improved memory and protected brain connections by reducing precursor proteins and boosting enzymes that degrade toxic waste.

Learner Engagement Detection: How AI Reads the Room When the Teacher Can't
Researchers have trained an AI model to identify student engagement levels through facial expressions with high accuracy. The study reveals a significant drop in attention after just six minutes and links emotional engagement to better test scores.

Sodium-sulfur Batteries: Anode-Free Design Challenges Conventional Limits
Researchers propose a high-voltage, anode-free battery architecture claiming exceptional energy density and significantly reduced costs. By utilising a sulfur tetrachloride cathode, the method attempts to overcome the voltage limitations inherent in traditional sodium-based systems.

The Shrinking Domain of the Persian Leopard: A Data-Driven Forecast
Researchers in Iran have modelled the current and future distribution of the Persian leopard, incorporating prey availability and climate projections. The study predicts that up to nearly 40% of suitable habitat in Fars Province could be lost by 2070 due to climate shifts.

A Mechanical Ratchet: Rethinking the Cytokinesis Mechanism in Vertebrates
New research reveals that early vertebrate embryos rely on a dynamic 'mechanical ratchet' system to divide, rather than the standard contractile ring. By alternating the stiffness of the cytoplasm, cells can anchor and advance the division machinery despite the physical challenges of a yolk-heavy environment.

The Evolutionary Blind Spot in Tropical Forest Carbon Loss
A new analysis reveals that small, permanent clearings drive the majority of carbon loss in humid tropical forests, rather than massive fires which forests often recover from. The study highlights how permanent land-use conversion disrupts the forest's evolutionary capacity for regrowth.

Tandem DNA Repeats: Somatic Instability and Organ Failure Risk
Analysis of over 900,000 genomes reveals that repetitive DNA sequences expand significantly with age, driven by inherited genetic modifiers. These somatic mutations are strongly linked to severe kidney and liver diseases, challenging the assumption that our genome remains static throughout life.

The TyG Index: Exposing the Silent Saboteur in the Human Heart
A study of 235 hypertensive patients identifies a simple calculation—the TyG index—as a superior detective for spotting metabolic syndrome and early heart damage compared to traditional weight metrics. It suggests that even normal-weight individuals may harbour invisible cardiac risks.
