Researchers extend non-line-of-sight imaging towards longer wavelengths

Emerging technologies for non-line-of-sight imaging can detect objects even if they are around a corner or behind a wall. In new work, researchers use a new type of detector to extend this method from visible light into near ...

Mathematician creates mass extinction model regarding climate change and adaptation

A RUDN University mathematician and a colleague developed a theoretical model of mass extinction. The model for the first time took into account two important factors—the inverse effect of vegetation on climate change and ...

Unraveling a paradox of Himalayan glacier melt

One in five glaciers on Earth are covered with a layer of rocky debris. The presence of debris influences how glaciers melt. In the Himalaya, debris covers most large glaciers, and it is so thick that it should insulate the ...

Discovery puts a magnetic spin on neuromorphic computing

The word "fractals" might inspire images of psychedelic colors spiraling into infinity in a computer animation. An invisible, but powerful and useful, version of this phenomenon exists in the realm of dynamic magnetic fractal ...

Tracking species range shifts in a changing climate

As our planet undergoes significant transformations due to climate change, habitats are being altered, appearing, disappearing, or changing in quality. Understanding the impact of these changes on the geographic distributions ...

Scientists uncover a surprising connection between number theory and evolutionary genetics

Number theory, the study of the properties of positive integers, is perhaps the purest form of mathematics. At first sight, it may seem far too abstract to apply to the natural world. In fact, the influential American number ...

Mixing of moiré-surface and bulk states: Capturing Hofstadter's butterfly in one of Earth's most ancient materials

Researchers in the National Graphene Institute (NGI) at The University of Manchester have revisited one of the most ancient materials on Earth—graphite—and discovered new physics that has eluded the field for decades.

Your genetic code has lots of 'words' for the same thing—information theory may help explain the redundancies

Nearly all life, from bacteria to humans, uses the same genetic code. This code acts as a dictionary, translating genes into the amino acids used to build proteins. The universality of the genetic code indicates a common ...
