(Phys.org) —It's been a busy week for space scientists—a team of astronomers discovered the first Thorne-Zytkow object—it's a weird type of hybrid between a red supergiant and a neutron star that looks like a regular ...
(Phys.org) —Quantum mechanics offers the potential for creating communication technologies with an inherently higher security level than today's classical technologies. Using quantum digital signatures (QDS), for example, ...
(Phys.org) —It is generally agreed that the ancestors of modern Native Americans were Asian peoples who migrated to North America from Siberia and Beringia – a region proximate to the Bering Strait, Bering Sea and Chukchi ...
For centuries, naturalists have puzzled over what might constitute the head of a sea star, commonly called a "starfish." When looking at a worm, or a fish, it's clear which end is the head and which is the tail. But with ...
