Lipids and DNA nanostructures independently control artificial cell mechanics

What if the mechanical properties of a cell could be programmed like the components of a machine? Researchers at the University of Tokyo have discovered that two fundamental modes of cellular deformation—stretching and bending—can be independently controlled using different molec

Scientists may have finally found how Alzheimer's spreads through the brain

A common brain protein may be giving Alzheimer’s disease an unexpected way to spread, carrying toxic Tau proteins from damaged neurons into healthy ones. By blocking these harmful protein packages before they reach new cells, researchers believe it may one day be possible to slow

The invasive fern that science misidentified for decades

Salvinia molesta can double its biomass in 36 hours. It spreads across ponds, lakes and slow-moving waterways in a smothering green mat, blocking sunlight, consuming oxygen and collapsing the ecosystems beneath it. Now present in freshwater bodies across more than 60 countries, i

Super-deep diamond discovery may rewrite Earth's role in preserving the building blocks of

Two diamonds formed 700 kilometers below the Earth's surface reveal a life-giving synchronicity between shifting continents and the cycling of phosphorus, a vital building block of DNA and cell membranes.

Single-atom catalyst turns lignin into valuable chemicals with near-complete conversion

Researchers at The University of Manchester and Hebei University of Technology have identified how a new class of catalyst can break down lignin into useful chemical building blocks, offering a more sustainable route to replace fossil-based materials.

How tall and short trees can coexist in old growth forests

Forests are shaped by light competition. The trees that grow the tallest have access to the most sunlight, blocking the rays and rendering the shaded space around them inhospitable to shorter trees below. In this stem exclusion phase of forest succession, the shorter trees often

Block-by-block AI maps uncover real urban air temperatures across 380 U.S. cities

Cities are often described as "heat islands," with media reports warning that some neighborhoods can be 20° F (7° C) hotter than others. But those temperatures are often based on satellite data rather than the conditions people actually experience, due to the dearth of near-surfa

Why gold never tarnishes has finally been explained

Gold may have a secret self-defense system that helps it resist tarnishing. Researchers discovered that atoms on gold surfaces reorganize themselves into patterns that block oxygen from reacting with the metal, suppressing oxidation by up to a trillion-fold. Beyond explaining why

Yale scientists may have found how Parkinson's disease spreads through the brain

Yale scientists discovered two neuron surface proteins that appear to help spread the toxic protein linked to Parkinson’s disease. Blocking these proteins in mice dramatically reduced disease progression, offering a potential new target for future therapies.

Study suggests increased biotoxicity due to anaerobic decolorization of diazo dye by wetla

Untreated synthetic dye effluents severely threaten aquatic ecosystems by blocking sunlight, depleting dissolved oxygen and releasing compounds with potential ecological toxicity. Among the various treatment strategies, biological treatment is considered a cost-effective and envi
