New study allows brain and artificial neurons to link up over the web
Brain-digital interface concept illustration (stock image). Credit: © knowhowfootage / Adobe Stock Brain functions are made possible by circuits of spiking neurons, connected together by microscopic, but highly complex links called synapses. In this new study, published in the scientific journal Nature Scientific Reports, the scientists created a hybrid neural network where biological and artificial…
Environmental oxygen triggers loss of webbed digits
African clawed frog (stock image). Credit: © Nathan / Adobe Stock Free fingers have many obvious advantages on land, such as in locomotion and grasping, while webbed fingers are typical of aquatic or gliding animals. But both amphibians and amniotes -- which include mammals, reptiles, and birds -- can have webbed digits. In new research…

Meteorite study suggests Earth may have been wet since it formed
Planet Earth (stock image). Credit: © dell / stock.adobe.com A new study finds that Earth's water may have come from materials that were present in the inner solar system at the time the planet formed -- instead of far-reaching comets or asteroids delivering such water. The findings published Aug. 28 in Science suggest that Earth…
Hubble maps giant halo around Andromeda Galaxy
This illustration shows the location of the 43 quasars scientists used to probe Andromeda's gaseous halo. These quasars--the very distant, brilliant cores of active galaxies powered by black holes--are scattered far behind the halo, allowing scientists to probe multiple regions. Looking through the immense halo at the quasars' light, the team observed how this light…

Cosmic rays may soon stymie quantum computing
Quantum computing abstract concept (stock image). Credit: © vchalup / stock.adobe.com The practicality of quantum computing hangs on the integrity of the quantum bit, or qubit. Qubits, the logic elements of quantum computers, are coherent two-level systems that represent quantum information. Each qubit has the strange ability to be in a quantum superposition, carrying aspects…
Meteorite strikes may create unexpected form of silica
Quartz (stock image). Credit: © ala / stock.adobe.com When a meteorite hurtles through the atmosphere and crashes to Earth, how does its violent impact alter the minerals found at the landing site? What can the short-lived chemical phases created by these extreme impacts teach scientists about the minerals existing at the high-temperature and pressure conditions…
A galaxy’s stop-and-start young radio jets
Multi-frequency composite VLBA image of the galaxy TXS 0128+554, 500 million light-years from Earth. The image shows young radio jets originating near a supermassive black hole at the core of the galaxy. The jets in this image started about 80 years ago, stopped, then resumed about 10 years ago.
