A beautiful butterfly is able to fool ants into rearing its young by masking them with the ants’ own smell, say researchers.

Caterpillars of the alcon blue butterfly have developed an outer coat that tricks ants into believing the young are its own, duping the ants into carrying the larvae back to their colonies to care for.

But what is more, the ant seems to “recognise” that it is being duped and one population appears to be engaging in an evolutionary arms race with the butterfly, says the team led by David Nash at the University of Copenhagen, Denmark.

When we think creatively, produce novel ideas, or otherwise have “Eureka” moments, we may actually unlock access to a dimension outside of our everyday perception, according to the controversial theory.

Scientists identified a new mechanism causing lithium-ion battery self-discharge and degradation: cathode hydrogenation. They revealed how protons and electrons from the electrolyte impact the cathode.

CRISPR, the gene-editing technology, has been one of the major breakthroughs in biology in the last two decades. And while students learn about the capability to cut, paste, and alter genes, it’s rare that they get the chance to understand the technology by using it themselves.

A discovery six years ago took the condensed-matter physics world by storm: Ultra-thin carbon stacked in two slightly askew layers became a superconductor, and changing the twist angle between layers could toggle their electrical properties. The landmark 2018 paper describing “magic-angle graphene superlattices” launched a new field called “twistronics,” and the first author was then-MIT graduate student and recent Harvard Junior Fellow Yuan Cao.

Together with Harvard physicists Amir Yacoby, Eric Mazur, and others, Cao and colleagues have built on that foundational work, smoothing a path for more twistronics science by inventing an easier way to twist and study many types of materials.

A new paper in Nature describes the team’s fingernail-sized machine that can twist thin materials at will, replacing the need to fabricate twisted devices one by one. Thin, 2D materials with properties that can be studied and manipulated easily have immense implications for higher-performance transistors, optical devices such as solar cells, and quantum computers, among other things.

In 1971, English mathematical physicist and Nobel-prize winner Roger Penrose proposed how energy could be extracted from a rotating black hole. He argued that this could be done by building a harness around the black hole’s accretion disk, where infalling matter is accelerated to close to the speed of light, triggering the release of energy in multiple wavelengths.

Since then, multiple researchers have suggested that advanced civilizations could use this method (the Penrose Process) to power their civilization and that this represents a technosignature we should be on the lookout for.

Examples include John M. Smart’s Transcension Hypothesis, a proposed resolution to the Fermi Paradox where he suggested advanced intelligence may migrate to the region surrounding black holes to take advantage of the energy available.
