Muscle Tissue from a 3D Printer – Produced in Zero Gravity

On their way into space, astronauts' bodies deteriorate dramatically in zero gravity. To address this problem and protect our pioneers in space, researchers are looking for realistic test models.

Oxidative Stress May Hold Clues to the Origins of Repetitive Behaviors

Abnormal repetitive behaviors in mice are strongly linked to multiple biomarkers of oxidative stress, which occurs when antioxidants cannot counteract the effects of harmful molecules in the body, according to a study published November 5, 2025, in the open-access journal PLOS One by Kendall Coden and Dr. Joseph Garner of Stanford University, U.S.

Ferroptosis Suppression Identified as a Key Driver of Lung Cancer Growth

NYU Langone Health researchers found that a type of cell death caused by a buildup of highly reactive molecules suppresses lung tumor growth.

Hidden Role of Biliverdin Reductase A in Fighting Oxidative Damage

According to a new study from Johns Hopkins Medicine, the enzyme biliverdin reductase A (BVRA) protects neurons directly from oxidative stress, regardless of whether it produces the yellow pigment bilirubin.

RNA Molecules Alter Genome Structure to Silence Critical Neuronal Genes During Stress

What if the brain's response to stress could be read not in fleeting neurotransmitter bursts, but in the quieting of genes deep inside chromatin? Researchers at the University of Alabama at Birmingham have now shown that stress hormones may silence crucial neuronal genes through an unexpected class of RNA molecules that operate not by encoding proteins, but by reshaping the genome's architecture.

Enzyme BVRA Found to Shield Neurons from Oxidative Stress

New research from Johns Hopkins Medicine shows that the enzyme biliverdin reductase A (BVRA) plays a direct protective role against oxidative stress in neurons, independent of its role producing the yellow pigment bilirubin.

Study Unveils the Complete Biosynthetic Loop Regulating Tannin Production in Strawberries

Hydrolyzable tannins (HTs), including gallotannins and ellagitannins, are essential polyphenolic compounds that influence fruit taste, antioxidant capacity, and stress tolerance. Although condensed tannin biosynthesis has been well studied, the enzymatic processes governing HT formation remain unclear.

Researchers Use Bacterium’s Own Defenses to Amplify Antibiotic Power

Scientists at St. Jude Children's Research Hospital have found a way to use a bacterium's own drug resistance mechanisms against itself, presenting a potentially safer and more effective way to treat certain antibiotic-resistant infections.

Precision Genome Editing of D3 Gene Enhances Rice Architecture and Stress Resilience

By precisely editing the D3 gene, which regulates both plant height and tillering, researchers developed compact, high-tillering rice plants that maintain grain yield while showing enhanced resistance to bacterial blight.

Research Sheds New Light On How Neurons Transmit Strains and Stresses

How do embryos develop? Why does the cortex of the mammalian brain fold? How do we feel touch at our fingertips? These and other fundamental biological questions remain unsolved. Yet, scientists know they all rely on a common principle: the conversion of a physical stimulus into a biochemical signal.
