A grant from the National Endowment for the Arts (NEA) will fund a new lab at Rice University that will explore this possible new inroad in the fight against such disorders. […]

A team of engineers at the UC Berkeley and the Keck Graduate Institute (KGI) of The Claremont Colleges combined CRISPR with electronic transistors made from graphene to create a new hand-held device that can detect specific genetic mutations in a matter of minutes. The device, dubbed CRISPR-Chip, could be used […]

University of Tokyo researchers and their collaborators have demonstrated that a special structure that forms when DNA is damaged helps to restore it. Human cells have a mechanism for recognizing this structure, consisting of DNA and RNA, which promotes accurate repair of damaged DNA. The study’s findings point to a […]

A machine-learning model from MIT researchers computationally breaks down how segments of amino acid chains determine a protein’s function, which could help researchers design and test new proteins for drug development or biological research. Proteins are linear chains of amino acids, connected by peptide bonds, that fold into exceedingly complex […]

Scientists have long known that tumors have many pockets of high acidity, usually found deep within the tumor where little oxygen is available. However, a new study from MIT researchers has found that tumor surfaces are also highly acidic, and that this acidity helps tumors to become more invasive and […]

New research, which appeared in the journal Proceedings of the Royal Society B, sheds light on how the damage in the brain caused by a stroke can lead to permanent vision impairment for approximately 265,000 Americans each year. The findings could provide researchers with a blueprint to better identify which areas […]

A new way of making scaffolding for biological cultures could make it possible to grow cells that are highly uniform in shape and size, and potentially with certain functions. The new approach uses an extremely fine-scale form of 3-D printing, using an electric field to draw fibers one-tenth the width […]

Women who shared their mother’s womb with a male twin are less likely to graduate from high school or college, have earned less by their early 30s and have lower fertility and marriage rates when compared with twins who are both female, according to new Northwestern University research. In the […]

The U.S. Food and Drug Administration today approved Mayzent (siponimod) tablets to treat adults with relapsing forms of multiple sclerosis (MS), to include clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease.

Life can depend upon the interaction of two proteins that come together along a metabolic pathway. There, they enable growth by creating fatty acids essential for ensuring that cell membranes form in a protective, fluid environment. While scientists have understood the basic enzymes involved in this fatty-acid biosynthesis, they have […]

Protein Kinase C (PKC) enzymes are crucial for a number of cellular activities, including cell survival, proliferation and migration — functions that must be carefully controlled lest cells get out of control and form a tumor. Researchers at University of California San Diego School of Medicine found that another enzyme, […]

A discovery about how exercise improves brain function could be harnessed for research into ageing, and boosting learning and memory.
