Antarctic ice cliffs may not contribute to sea-level rise as much as predicted

Antarctica's ice sheet spans close to twice the area of the contiguous United States, and its land boundary is buttressed by massive, floating ice shelves extending hundreds of miles out over the frigid waters of the Southern ...

How cytoplasm 'feels' to a cell's components

Under a microscope, a cell's cytoplasm can resemble a tiny underwater version of New York's Times Square: Thousands of proteins swarm through a cytoplasm's watery environment, coming together and breaking apart like a cytoskeletal ...

Flexible, stretchable fire-ant rafts

What do Jell-O, toothpaste, and floating fire-ant rafts have in common? All are so-called "viscoelastic" materials, meaning that they can both resist flow under stress, like honey, and they can bounce back to their original ...

High-speed camera captures a water jet's splashy impact as it pierces a droplet

Squirting a jet of water through a drop of liquid may sound like idle fun, but if done precisely, and understood thoroughly, the splashy exercise could help scientists identify ways to inject fluids such as vaccines through ...

Warm ice may fracture differently than cold ice

Researchers at Aalto University have found strong evidence that warm ice—that is, ice very close in temperature to zero degrees Celsius—may fracture differently as compared to the kinds of ice typically studied in laboratories ...
