Phys.org / Porpoises can 'turn down the volume' to withstand ship noise

Porpoises are entirely dependent on their hearing for survival. They navigate, hunt, and communicate by emitting rapid click sounds and listening to the returning echoes. However, with increasingly noisy oceans, it is getting ...

Phys.org / Chemists create complex DNA structures without hydrogen bonds

No "sticky ends"? No problem. A new study by NYU chemists finds that DNA tiles can assemble into 3D structures without the sticky cohesion of hydrogen bonding. This finding, published in Nature Communications, turns a fundamental ...

Phys.org / Greenhouse gas fluxes in Everglades provide path for maximizing carbon capture via water management

The Florida Everglades is a complicated climate actor. The 1.5-million-acre wetland system remains a carbon sink, removing an average of 13.7 million metric tons of carbon dioxide from the atmosphere each year, but the system ...

Phys.org / Isolating vesicle-cloaked viruses in city and hospital wastewater

Viruses such as human norovirus can travel in vesicles, small fluid-filled sacs that are like shipping containers for cells. Viruses hidden in these containers are often harder to detect and may be more infectious than free-floating ...

Phys.org / Self-propelling microbes switch up swimming strategy to optimize light intake

Researchers in Hong Kong and the UK have revealed how one species of self-propelling microbes can actively change the path of their swimming motions, depending on how much light they receive. Reporting in Physical Review ...
