Protein ‘big bang’ reveals molecular makeup for medicine and bioengineering

Proteins have been quietly taking over our lives since the COVID-19 pandemic began. We’ve been living at the whim of the virus’s so-called “spike” protein, which has mutated dozens of…

How plants quickly adapt to shifting environmental conditions

Scientists — and gardeners — have long known that plants grow taller and flower sooner when they are shaded by close-growing neighbors. Now, for the first time, researchers at the…

Female fruit flies suppressed: Potential to make pests plummet

Populations of Drosophila suzukii fruit flies — so-called “spotted-wing Drosophila” that devastate soft-skinned fruit in North America, Europe and parts of South America — could be greatly suppressed with the…

A new class of functional elements in the human genome?

Some regions of the human genome where the DNA can fold into unusual three-dimensional structures called G-quadruplexes (G4s) show signs that they are preserved by natural selection. When G4s are…

Success in reversing dementia in mice sets the stage for human clinical trials

Researchers have identified a new treatment candidate that appears to not only halt neurodegenerative symptoms in mouse models of dementia and Alzheimer’s disease, but also reverse the effects of the…

Cell biology: Masters of synapse modulation

Ludwig-Maximilians-Universitaet (LMU) in Munich researchers have shown how RNA-binding proteins modulate synaptic responses that mediate the transmission of nerve cell impulses. Cells in the central nervous system possess a high…
