New research shows that fishes on either side of Niagara Falls—one of the most powerful waterfalls in the world—are unlikely to breed with one another. Knowing how well the falls serves as a barrier to fish movement is ...

Synchronized swimming: Biology on a micro-scale

Specialized stringy fluids flow through the human joints and help constitute substances such as mucus. These fluids contain long, flexible molecules like polymers or proteins, giving them the ability to stretch and absorb ...

Pilot plant in Vietnam: Water for 10,000 people

More than 20 percent of the world's population are dependent on karst groundwater. In these regions, large amounts of water seep into the porous rock and are available at great depths only. Moreover, karst water is susceptible ...

Neural networks will help manufacture carbon nanotubes

Thin films made of carbon nanotubes hold a lot of promise for advanced optoelectronics, energy and medicine, however with their manufacturing process subject to close supervision and stringent standardization requirements, ...

How bacteria swim against the flow

It is well known that bacteria can swim against the current, which often causes serious problems—for example, when they spread in water pipes or in medical catheters. To prevent or at least slow down the spread of bacteria ...
