Molecular morphers: DNA-powered gels shape-shift on command
Johns Hopkins engineers have developed gel strips that change shape when given chemical instructions written in DNA code. These "gel automata," measuring just centimeters, can grow or shrink, transforming from one letter or number to another when tri.....»»
Opinion: The peer review system no longer works to guarantee academic rigor—a different approach is needed
Peer review is a central feature of academic work. It's the process through which research ends up published in an academic journal: independent experts scrutinize the work of another researcher in order to recommend if it should be accepted by a pub.....»»

New technique points to unexpected uses for snoRNA across many cell types
Dynamic, reversible modifications of DNA and RNA regulate how genes are expressed and transcribed, which can influence cellular processes, disease development, and overall organismal health. Small nucleolar RNAs (snoRNAs) are a common but overlooked.....»»
Quantum-inspired design boosts efficiency of heat-to-electricity conversion
Researchers at Rice University have found a new way to improve a key element of thermophotovoltaic (TPV) systems, which convert heat into electricity via light. Using an unconventional approach inspired by quantum physics, Rice engineer Gururaj Naik.....»»
Using gas bubbles to precisely deliver nanomedicines shows promise for lung cancer treatment
The delivery of nanomedicines using gas bubbles has shown itself to be a unique way of transporting cytotoxins to the lungs of cancer patients. The method enables precise and focused treatments, and the local action of the drugs also prevents a range.....»»
A vision-driven approach: Researchers advocate use of imagination in tackling climate crisis
In a new npj Ocean Sustainability article, ten researchers advocate the use of imagination in tackling the climate crisis. They focus specifically on urbanizing river deltas, which are of great social and economic importance and highly vulnerable to.....»»
Red squirrels are very flexible in shifting their daily routines to avoid urban threats, researchers find
