Exploring topology in biology

When can we say that a certain property of a system is robust? Intuitively, robustness implies that, even under the effect of external perturbations on the system, no matter how strong or random, said property remains unchanged. ...

New light on baryonic matter and gravity on cosmic scales

Scientists estimate that dark matter and dark energy together are some 95% of the gravitational material in the universe while the remaining 5% is baryonic matter, which is the "normal" matter composing stars, planets and ...

Vibrating 2-D materials

Current electronic components in computers, mobile phones and many other devices are based on microstructured silicon carriers. However, this technology has almost reached its physical limits and the smallest possible structure ...

Astronomers find signature of magnetar outbursts in nearby galaxies

Apart from black holes, magnetars may be the most extreme stars in the universe. With a diameter less than the length of Manhattan, they pack more mass than that of our sun, wield the largest magnetic field of any known object—more ...

Transmitting data from space to earth with laser filaments

Could light be used to transmit information between satellites and Earth? Atmospheric water vapor scatters and absorbs light energy, but overcome that obstacle, and light will carry far more information and move it faster ...

Manifestation of quantum distance in flat band materials

The geometry of an object indicates its shape or the relationship of its parts to each other. Did you know that the electrons in solids also have geometric structures? In quantum mechanics, an electron in solids takes the ...
