New study shows superior reactive oxygen species removal ability of copper coupled to lysozyme
Tokyo University of Science

In aerobic organisms, reactive oxygen species (ROS), such as hydroxide (OH), singlet oxygen (1O2), hydrogen peroxide (H2O2), and superoxide (O2–) ions are produced during aerobic respiration, which causes serious oxidative damage to biomolecules in the body.

Gene mutation linked to poorer TBI recovery outcomes in African Americans, according to study
University of Texas Health Science Center at Houston

African Americans with a mutation in the gene TRPM4 are more likely to have increased inflammation in the brain, resulting in poor recovery after suffering a traumatic brain injury (TBI), compared to others who don’t have the mutation, according to a study by researchers with UTHealth Houston.

Eruption of Tonga underwater volcano found to disrupt satellite signals halfway around the world
Nagoya University

An international team has used satellite- and ground-based ionospheric observations to demonstrate that an air pressure wave triggered by volcanic eruptions could produce an equatorial plasma bubble (EPB) in the ionosphere, severely disrupting satellite-based communications.

'Love hormone' guides young songbirds in choice of 'voice coach'
Emory University

Oxytocin, the so-called “love hormone,” plays a key role in the process of how a young zebra finch learns to sing by imitating its elders, suggests a new study by neuroscientists at Emory University. Scientific Reports published the findings, which add to the understanding of the neurochemistry of social learning.

How “extracellular chaperones” help remove abnormal proteins
Chiba University

Proteins tend to fold wrongly and become defective when exposed to stressors such as heat, oxidation, and pH changes. Accumulation of abnormal proteins contributes to neurodegenerative diseases like Alzheimer’s.

To Track Turbulence in Tokamaks, Researchers Turn to Machine Learning
Department of Energy, Office of Science

Fusion energy researchers use a technique called Gas-Puff Imaging (GPI) to visualize an important phenomenon in tokamak devices involving turbulence in plasma magnetic confinement fields. This technique can generate roughly 1 million frames of visual data, far too much for humans to analyze by eye. Scientists recently tested a machine-learning based approach for analyzing GPI images. The system provides detailed, time- and space-resolved information and could aid in design and operation of future fusion power devices.
