Physics of cilia explain sperm's successful swimming
Sperm can't claim all the credit for their strong swimming. Carpets of tiny hairs lining the inside of the fallopian tubes give them an extra boost, propelling them upwards.

The isolation of graphene more than a decade ago transformed the landscape of condensed-matter physics, as the single-atom-thick, two-dimensional material exhibited high crystal and electronic quality to represent a conceptually ...
Many of the biggest questions in physics can be answered with the help of quantum field theories: They are needed to describe the dynamics of many interacting particles, and thus they are just as important in solid state ...

By precisely tracing a small, almost imperceptible, wobble in a nearby star's motion through space, astronomers have discovered a Jupiter-like planet orbiting that star, which is one of a binary pair. Their work, using the ...

(Phys.org)—Astrophysicist Konstantin Batygin has published a paper in the journal Nature arguing that the reason some planets lie in a tilt off the equatorial plane of their sun is because of the prior existence of another ...
