Theory that ridged skin helps dolphins debunked

A dolphin is obviously not a golf ball. However, many scientists believed that the way one slips through the water and the other through the air owed to the same cause: similarities in surface texture and their effect on ...

Using the power of math to improve food texture, consistency

The word starch brings to mind for many people either a food component or something used to stiffen clothing—but its use covers much territory. Starch is used in a wide variety of food and non-food settings. In fact, the ...

Sensing food textures is a matter of pressure

Food's texture affects whether it is eaten, liked or rejected, according to Penn State researchers, who say some people are better at detecting even minor differences in consistency because their tongues can perceive particle ...

Dowsing for electric fields in liquid crystals

You may not know it, but you probably spend several hours a day looking at nematic liquid crystals; they are used in virtually every smartphone, computer and TV screen. They are liquids composed of elongated molecules, which ...

Chelated calcium benefits poinsettias

Vegetatively propagated unrooted cuttings of annual ornamentals are typically grown in equatorial locations and shipped via airfreight to propagators located in temperate climates. Cutting quality, defined as the resistance ...

First observation of a square lattice of merons and antimerons

Scientists have, for the first time, observed a square lattice of merons and antimerons—tiny magnetic vortices and antivortices that form in a thin plate of the helical magnet Co8Zn9Mn3. By finely varying a magnetic field ...
