A theory suggests putting graphene on an undulating surface stresses it enough to create a minute electromagnetic field. The phenomenon could be useful for creating 2D electron optics or valleytronics devices.

Researchers were inspired by marinated eggs to demonstrate how diffusion works in an easy and quantifiable way. The basis of the recipe is marinating hard boiled eggs in vinegar or brine, which cures the eggs by sufficiently saturating the egg whites via diffusion. In their experiment, the researchers compared penetration levels of red food dye in the whites of peeled hard-boiled eggs at three different temperatures: refrigerator temperature, room temperature, and in a cool convection oven.

A new atomic nucleus 149-Lutetium, consisting of 71 protons and 78 neutrons, has been synthesized.

White dwarfs were once normal stars similar to the Sun but then collapsed after exhausting all their fuel. These interstellar remnants have historically been difficult to study. However, a recent study reveals new information about the movement patterns of these puzzling stars.

In biophysics, the kinetic states of molecules play a determining role in the metabolic and physiological processes in which they take part. Now, a new article specifies for the first time the levels of energy, the entropy and the enthalpy of protein folding. To do so, the team used a device with optical tweezers that enables changing the experimental temperature between 5ºC and 40ºC.
