There aren't any native lion or tiger populations living in Japan today, but this was not always the case. Fossil evidence indicates that at least one species of large cat roamed the archipelago during the Late Pleistocene—a ...

Although humans' visual perception of the world appears complete, our eyes contain a visual blind spot where the optic nerve connects to the retina. Scientists are still uncertain whether the brain fully compensates for the ...

New analysis on 2017 Hubble images of the Jupiter-family comet, 41P/Tuttle–Giacobini–Kresak (41P/TGK), indicates that the comet underwent a spin reversal between April and December 2017. While this behavior is not unheard ...

Scientists have long known that Earth's core is mostly made of iron, but the density is not high enough for it to be pure iron, meaning lighter elements exist in the core, as well. In particular, it's suspected to be a major ...

In 1958, an amateur archaeologist named John Cowles excavated the Cougar Mountain Cave in Oregon and retained many of the artifacts found there. Upon his death in the 1980s, these items were transferred to the Favell Museum ...

The global demand for lithium has skyrocketed over the last several years due to the rapid growth of the electric vehicle market and grid-storage solutions. Currently, production capacity is limited and unlikely to meet future ...

Concerns that quantum computers may start easily hacking into previously secure communications has motivated researchers to work on innovative new ways to encrypt information. One such method is quantum key distribution (QKD), ...

Historical accounts of the Punic Wars—and many other ancient wars—often paint a picture of soldiers riding in on imposing "war elephants." Yet, no skeletal remains of these war elephants had ever been found from the Punic ...

Dopamine—a neurotransmitter responsible for influencing motivation, pleasure, mood and learning in the brain—has experienced a bit of fame in recent years, acting as a sort of buzzword to describe a fleeting satisfaction ...

Mantle plumes beneath volcanic hotspots, like Hawaii, Iceland, and the Galapagos, seem to be anchored into a large structure within the core-mantle boundary (CMB). A new study, published in Science Advances, takes a deeper ...

Quantum chaos describes chaotic classical dynamical systems in terms of quantum theory, but simulations of these systems are limited by computational resources. However, one team seems to have found a way by leveraging error ...

King cobras are the world's longest venomous snakes. So, imagine seeing one a few feet away as you embark on a train in India. The Western Ghats King Cobra (Ophiophagus kaalinga)—a vulnerable king cobra species found in India's ...

Physical systems become inherently more complicated and difficult to produce in a lab as the number of dimensions they exist in increases—even more so in quantum systems. While discrete time crystals (DTCs) had been previously ...

A recent review of over 312 studies has identified dozens of unique uses of roadkill in scientific research. The review, published in Biology Letters, discusses the advantages of using roadkill instead of live wildlife and ...

Many organisms leverage showy colors for attracting mates. Because color is a property of light (determined by its wavelength), it is easy for humans to see how these colors are used in animal courting rituals. Less obvious ...
