According to a new study, tangles in unwound DNA can create mutational hotspots in the genomes of bacteria.

New research details a novel method called Repair-seq that reveals in exquisite detail how genome editing tools work.

One potential solution to the plastic waste problem, a biodegradable polymer called polylactide, has so far not fully lived up to its promise, showing little sign of breakdown once in seawater. In a new study, researchers set out to address this issue by incorporating RNA-inspired breaking points to the polymer.

Researchers have uncovered that reducing levels of the protein tau, known for its role in Alzheimer’s disease and other neurodegenerative conditions, changes excitatory and inhibitory cells in ways that make it harder for the brain to burst with overexcitation.

Cell fitness has been identified as a way of predicting health outcomes in COVID-19 patients, according to a University of Queensland study.

Researchers have shown that protein analysis at the single-cell level in a tumor sample can be used to detect cancer stem cells that evade chemotherapy.

Nearly half of our DNA has been written off as junk, but research over the last decade has shown that some of this genetic "dark matter" does have a function. Biologists continue to debate, however, whether these regulatory sequences of DNA are essential. A new study has explored the function of transposons, a component of junk DNA, and shows that at least one family plays a critical role in viability in mice.

Over the last few decades, scientists have discovered that long-term calorie restriction provides benefits in animals including lower weight, better blood sugar control and longer lifespans. Researchers have now found that fasting is essential for mice to derive full benefit from calorie restriction.

Encasing algal protein in liquid droplets was found to dramatically enhance the algae’s light-harvesting and energy-conversion properties by up to three times. This research may lead towards a new, sustainable way of generating electricity from sunlight.

The first atlas of metabolites in the mouse brain has been published and includes 1,547 different molecules across 10 brain regions in male and female laboratory mice from adolescence to advanced old age.
