Another 50 or so shorter-lived radionuclides, such as radium-226 and radon-222, found on Earth, are the products of decay chains that began with the primordial nuclides, or are the product of ongoing ...

It’s the rarest particle decay ever discovered. Scientists have clinched the case for a special type of decay of subatomic particles called kaons. Further study of the rare decay could reveal a ...

Strange, ultraheavy stars that are rich in barium grow massive by cannibalizing their companions, scientists discover after finally catching these stellar leeches in the act. A strange type of ...

The reaction rate of barium-139 as it turns into barium-140 has been a dominant source of uncertainty in predictive models used to determine the presence of isotopes of heavy elements in stars.

Chain gangs developed as a popular solution to that problem. Chain gangs were groups of convicts forced to labor at tasks such as road construction, ditch digging, or farming while chained together.

Chainsaw chains are the part of the chainsaw blade that cuts through wood. Over time, the chain can stretch slightly during use, which reduces the saw’s wood-cutting effectiveness, slows down ...

This food chain shows a leaf is eaten by a worm, which is then eaten by a bird. The arrow means 'is eaten by'. A food chain always starts with a producer. This is an organism that makes its own food.

An early line printer that used type slugs linked together in a chain as its printing mechanism. The chain spun horizontally around a set of hammers. When the desired character was in front of the ...

The company demonstrated optimized two-qubit gates on barium with greater than 99.9% fidelity in a two-ion chain via the same mechanisms used to realize two-qubit gates in IonQ's production ...

Black-crowned night-heron. This predator is adapted to hunt at night. In the French Guiana this is one of the major night heron species with its cousin the Yellow-crowned night-heron (Nycticorax ...
