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…

Higher concentration of metal in Moon’s craters provides new insights to its origin

The Moon (stock image). Credit: © David Woods / stock.adobe.com Life on Earth would not be possible without the Moon; it keeps our planet's axis of rotation stable, which controls seasons and regulates our climate. However, there has been considerable debate over how the Moon was formed. The popular hypothesis contends that the Moon was…

Newer variant of COVID-19-causing virus dominates global infections

Coronavirus illustration (stock image). Credit: © dottedyeti / stock.adobe.com Research out today in the journal Cell shows that a specific change in the SARS-CoV-2 coronavirus virus genome, previously associated with increased viral transmission and the spread of COVID-19, is more infectious in cell culture. The variant in question, D614G, makes a small but effective change…

Researchers identify multiple molecules that shut down SARS-Cov-2 polymerase reaction

Coronavirus illustration (stock image). Credit: © dermatzke / stock.adobe.com SARS-CoV-2, the coronavirus causing the global COVID-19 pandemic, uses a protein called polymerase to replicate its genome inside infected human cells. Terminating the polymerase reaction will stop the growth of the coronavirus, leading to its eradication by the human host's immune system. Researchers at Columbia Engineering…

Asteroid impact, not volcanoes, made the Earth uninhabitable for dinosaurs

Illustration of dinosaurs and asteroid (stock image). Credit: © lassedesignen / stock.adobe.com Modelling of the Chicxulub asteroid impact 66 million years ago shows it created a world largely unsuitable for dinosaurs to live in. The asteroid, which struck the Earth off the coast of Mexico at the end of the Cretaceous era 66 million years…

Researchers use 3D modeling to decode aerial undulation’s role in flying snake glides

Paradise tree snake (stock image). Credit: © Alessandro / stock.adobe.com When the paradise tree snake flies from one tall branch to another, its body ripples with waves like green cursive on a blank pad of blue sky. That movement, aerial undulation, happens in each glide made by members of the Chrysopelea family, the only known…

Major new paleoclimatology study shows global warming has upended 6,500 years of cooling

Glacier collapse (stock image). Credit: © volki / stock.adobe.com Over the past 150 years, global warming has more than undone the global cooling that occurred over the past six millennia, according to a major study published June 30 in Nature Research's Scientific Data, "Holocene global mean surface temperature, a multi-method reconstruction approach." The findings show…

A cosmic mystery: ESO telescope captures the disappearance of a massive star

Very Large Telescope complex (stock image). Credit: © CPO / stock.adobe.com Using the European Southern Observatory's Very Large Telescope (VLT), astronomers have discovered the absence of an unstable massive star in a dwarf galaxy. Scientists think this could indicate that the star became less bright and partially obscured by dust. An alternative explanation is that…
