No more needles for diagnostic tests?

IMAGE: Engineers at the McKelvey School of Engineering at Washington University in St. Louis have developed a microneedle patch that can be applied to the skin, capture a biomarker of interest… view more  Credit: Image: Sisi Cao Blood draws are no fun. They hurt. Veins can burst, or even roll — like they’re trying to avoid […]

Squid-inspired robot swims with nature’s most efficient marine animals

Scientists at the University of Southampton and University of Edinburgh have developed a flexible underwater robot that can propel itself through water in the same style as nature’s most efficient swimmer – the Aurelia aurita jellyfish. The findings, published in Science Robotics, demonstrate that the new underwater robot can swim as quickly and efficiently as […]

An anode-free zinc battery that could someday store renewable energy

Renewable energy sources, such as wind and solar power, could help decrease the world’s reliance on fossil fuels. But first, power companies need a safe, cost-effective way to store the energy for later use. Massive lithium-ion batteries can do the job, but they suffer from safety issues and limited lithium availability. Now, researchers reporting in […]

Genetic rewiring behind spectacular evolutionary explosion in East Africa

(Jan. 19, 2021) – A look at RNA tells us what our genes are telling our cells to do, and scientists say looking directly at the RNA of brain tumor cells appears to provide objective, efficient evidence […]

Eliminating microplastics in wastewater directly at the source

The results of this research have been published in the Environmental Pollution […]

Simulating evolution to understand a hidden switch

IMAGE: Using computer simulations built on reasonable assumptions and conducted under careful control, computational bioscientists can mimic real biological conditions. Starting with the original founding population (ancient phase), they can evolve… view more  Credit: © 2021 KAUST; Anastasia Serin Computer simulations of cells evolving over tens of thousands of generations reveal why some organisms retain a […]

New videos show RNA as it’s never been seen

A new Northwestern University-led study is unfolding the mystery of how RNA molecules fold themselves to fit inside cells and perform specific functions. The findings could potentially break down a barrier to understanding and developing treatments for RNA-related diseases, including spinal muscular atrophy and perhaps even the novel coronavirus. “RNA folding is a dynamic process […]
