Two-dimensional magnetic crystals and emergent heterostructure devices

BACKGROUND The electron can be considered a tiny magnet, with two opposite poles that define its magnetic field associated with the spin and the orbital movement. When such tiny magnets are collectively aligned as a result of intrinsic coupling, ferromagnetism emerges. However, it has long been believed that ferromagnetism survived fatigue in two-dimensional (2D) systems due to the greater thermal …

Great white sharks may have driven megalodons to extinction — Quartz

There is a new suspicion in the mystery of the megalodon extinction. For years, scientists have been trying to reconstruct why the biggest shark ever to terrorize the seas disappeared a few million years ago. Previous research suggests that behemoth predators became extinct around 2.6 million years ago, along with a series of early seals, walruses, dolphins and whales, in …

Gravitational waves: Black hole detector to get upgrade

Image copyright NSF Picture caption The LIGO Louisiana laboratory that detected gravitational waves is online for an update British and US governments announced a £ 25 million upgrade to machines that detected gravitational waves three and a half years ago. The improved instruments will be able to detect collisions of black holes almost twice as high as By 2024 they …
