Research reveals how natural enzymes transcribe expanded eight-letter genetic code

All known life on earth utilizes the same genetic alphabet, consisting of four letters. Now, researchers at University of California San Diego have demonstrated that one of biology's most essential enzymes can accurately read and transcribe an expanded, eight-letter genetic alphabet.

Faulty myelin-making brain cells may help drive cognitive decline with age

Researchers found that greater age-related cognitive decline was associated with more dysfunctional oligodendrocytes, reduced NRF2 expression, smaller myelinated axons, and abnormally thicker myelin in human white matter. Experiments in mice showed that deleting NRF2 specifically from oligodendrocytes reproduced key white matter abnormalities and reduced cognitive improvement over time, implicating this pathway in cognitive aging.

A Mediterranean ingredient gave gluten-free pasta an unexpected upgrade

Researchers developed carob-enriched gluten-free tagliatelle that increased dietary fiber and antioxidant activity while reducing starch digestibility and improving pasta structure. A 20% carob substitution provided the best overall balance of functional properties, texture, and consumer acceptance, although clinical health benefits remain to be established.

ESCRT-III proteins play an unexpected role in protecting DNA bridges during cell division

Every time a cell divides, it must accurately copy and distribute its DNA between two new cells. However, in some cases, chromosomes do not fully separate, leaving behind thin strands of DNA known as DNA bridges that connect the two newly formed cells.

Researchers uncover molecular switch controlling nutrient-driven cell growth

Cells carry their own growth switches. When enough nutrients-amino acids in particular-are available, cells flip this switch on and begin to grow. Researchers at KAIST and Yonsei University have now uncovered the molecular mechanism by which amino acid signals activate this cellular growth switch.
