Phys.org / Hannibal's famous war elephants: Single bone in Spain offers first direct evidence

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 ...

Medical Xpress / Addiction and appetite along the gut-brain axis: Vagus nerve may play a crucial role in the dopamine reward pathway

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 ...

Phys.org / Solid, iron-rich megastructure under Hawaii slows seismic waves and may drive plume upwelling

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 ...

Phys.org / 91-qubit processor accurately simulates many-body quantum chaos

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 ...

Phys.org / Snakes on trains: King cobras are 'hopping railways' to unsuitable habitats in India

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 ...

Phys.org / 2D discrete time crystals realized on a quantum computer for the first time

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 ...

Phys.org / Cuttlefish use polarized light to create a dramatic mating display invisible to humans

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 ...

Phys.org / How starfish control tube feet without a central nervous system or brain

Starfish, also known as sea stars, are equipped with an almost alien-like anatomy. Despite lacking a brain, blood, and central nervous system, these odd creatures still have locomotive abilities. The structure of their many ...

Phys.org / Shipping regulations to reduce pollution may have exacerbated Great Barrier Reef bleaching

Rising ocean temperatures have been implicated in mass coral bleaching events affecting the Great Barrier Reef (GBR). These events have been increasingly frequent, with major events occurring in 2016, 2017, 2020, 2022, 2024, ...
