Surprising link between metallicity and superconductivity uncovered in twisted trilayer graphene

Superconductivity is a state of matter characterized by an electrical resistance of zero, typically at very low temperatures. Past studies have found that in various materials, this unique state is accompanied by unusual ...

Universal quantum protocol extracts maximum work without knowing a system's state in advance

A new study published in Nature Communications has shown that in the asymptotic limit, extracting the maximum possible work from many copies of a quantum system does not require knowing exactly what state that system is in.

PFAS detected in dolphin milk may pass from mothers to calves

Researchers have found that a group of chemicals known as PFAS can be transferred from mother dolphins to their nursing calves, adding to the evidence that these persistent contaminants can be transferred from mothers to ...

Cutting calories to slow aging—without compromising health

Restricting calorie intake in species such as mice, rhesus monkeys, and fruit flies has been shown to extend their lifespans. In some cases, these animals not only live longer, but are also free of disease. But when pushed ...

The moon might be more prone to fires

Engineers love a good practical challenge, especially when it comes to spaceflight. But there's one particular challenge facing the crewed missions of the near future that scares mission planners above almost all others—fire. ...

Immune cells in the nose slow influenza virus, study finds

A new study from the University of Gothenburg may help guide the development of better influenza vaccines. Memory cells in the nose slow the influenza virus as soon as it enters the body. They reduce viral levels and may ...

In world first, antimatter taken on test drive at CERN

CERN scientists on Tuesday pulled off the unprecedented feat of transporting antiprotons by road, successfully test-driving the world's first antimatter delivery system, with an eye to one day supplying research labs across ...

The time capsule in the salt flat

There is a place in northern Chile, 3,500 meters above sea level in the Andean Altiplano, where almost nothing survives. The Salar de Pajonales is a salt flat of savage extremes temperatures swinging from −23°C to 26°C, solar ...

The world's waste mountain is rising at an alarming rate

The world is struggling to deal with ever-growing quantities of waste. A new World Bank Group report, What a Waste 3.0, shows that more than 2.6 billion tonnes of municipal solid waste (which includes rubbish from households, ...

The moon that tipped a planet

Neptune is the solar system's most distant planet, a cold, blue ice giant sitting nearly 30 times further from the sun than Earth. At that remote distance, temperatures plunge to nearly minus 200 degrees Celsius and a single ...

Black hole mergers test the limits of general relativity

General relativity stands as one of the bedrock theories in modern physics. Its strange view of relative time and space has been confirmed by countless experimental and observational tests, from rotational frame dragging ...
