Exposed ends and bends attract DNA-cutting enzymes, live imaging reveals

Researchers at the Nano Life Science Institute (WPI-NanoLSI) at Kanazawa University have directly visualized how enzymes find and break DNA molecules in real time. Using high-speed atomic force microscopy, the team followed individual enzymes as they moved along DNA and found tha

Ancient spearheads reveal how Ice Age humans learned the land

At the end of the last ice age, early humans crisscrossed the Americas following seasons, rivers and game, often with a trusty spear in hand. Nearly 13,000 years later, archaeologists are using those spearheads to study how America's first inhabitants understood risk.

Invasive marine species set to take advantage of rising seas

More than two-thirds of newly flooded coastlines worldwide could become suitable habitat for 122 non-native marine species—including Chinese mitten crabs, Pacific oysters and Asian tiger shrimp—by the middle and end of this century. The research, published in Nature Ecology & Evo

How to balance quantum batteries' high power with stable energy delivery

Quantum batteries are an emerging area of research, with progress coming from theoretical studies and proof-of-principle experiments in small quantum systems. Unlike conventional chemical batteries used in everyday life, they use quantum systems to store and transfer energy. Rese
