When we think about heat traveling through a material, we typically picture diffusive transport, a process that transfers heat from high-temperature to low-temperature as particles and molecules bump into each other, losing kinetic energy in the process. But in some materials, heat can travel in a different way, flowing like water in a pipeline that—at least in principle—can be forced to move in a direction of choice. This second regime is called hydrodynamic heat transport.
In a new study published in Physical Review Letters, researchers used machine learning to discover multiple new classes of two-dimensional memories, systems that can reliably store information despite constant environmental noise. The findings indicate that robust information storage is considerably richer than previously understood.
In a new study, researchers say that nonbiological sources they considered could not fully account for the abundance of organic compounds in a sample collected on Mars by NASA’s Curiosity rover. The paper is published in the journal Astrobiology.
The existence of massive, elliptical galaxies in the early universe has puzzled astronomers for two decades. An international team led by Nikolaus Sulzenauer and Axel Weiß from the Max Planck Institute for Radio Astronomy (MPIfR) used data from the Atacama Large Millimeter/submillimeter Array (ALMA) to shed light on this open question of galaxy formation. They studied one of the most spectacular galaxy aggregations in great detail and published their results in the current issue of The Astrophysical Journal.
Dark matter is a type of matter that is predicted to make up most of the matter in the universe, yet it is very difficult to detect using conventional experimental techniques, as it does not emit, absorb, or reflect light. While some past studies gathered indirect hints of its existence, dark matter has never been directly observed; thus, its composition remains a mystery.
Using NASA’s Fermi Gamma-ray Space Telescope, Chinese astronomers have observed a gamma-ray binary system known as PSR J2032+4127. Results of the new observations, published February 3 on the arXiv preprint server, shed more light on the orbital parameters of this binary, which could help us better understand its nature.
In a tightly controlled manufacturing hangar west of Paris, workers put the finishing touches on an enormous silver-colored engine. In just a few days, a similar machine will help propel the most powerful version of Europe’s Ariane 6 rocket yet, flying for the first time with four boosters.

An ornithologist from the University of North Carolina, Wilmington, Steven Emslie, has studied penguins in Antarctica for over 15 years. Over the years, he’s discovered penguin remains from abandoned penguin colonies, tracing clues about climate changes. In recent years, Emslie says a warming trend has reached deeper into the continent than before. As the ice has melted, it has exposed a penguin colony dating back thousands of years. In September 2020, he reported the news that he found ancient naturally mummified penguins. Although they looked as though they might be recently deceased, the penguins date back from 800 to 5,000 years ago. Despite so many years, the penguin’s feathers remained intact. Flesh remained as if the birds had died recently. Also, stains from the bird’s waste were still apparent on rocks as if no time had passed. Ancient penguin mummiesEmslie described what he found:
The Adélie penguins used the nesting grounds for thousands of years. Strewn about the site, countless pebbles are a tell-tale sign. As Adélie penguins nest, they gather pebbles to protect their eggs. As recently as 100 years ago, nothing was found at the same location by early explorers. Today, after 800 years, the ancient colony is once again visible. What happened to the penguin colony?According to the Times:
Today, sea levels are rising along with temperatures. Fortunately, Adélie penguins alive today are proving adaptable, seeking out new nesting grounds. Now, the scientist believes they will return to their ancestor’s old nesting ground. Finding the wealth of pebbles already in place, they may find the location highly desirable.

Studying NASA satellite images, they spotted penguin feces in the remote Danger Islands. Before the discovery, researchers believed the penguin populations were on the decline. Afterward, they counted over 750K pairs of penguins.

Mostly by cruise ships, there could be more than 78,500 visitors this year, up from 56,000 tourists in the two prior years. As humans begin to arrive more frequently, scientists fear they will disrupt the fragile, relatively untouched environment. Along with the people, insects and plant seeds could arrive. Thus, isolated penguin colonies and other wildlife will have to rapidly adapt to more than climate change alone. Antarctica has seen incredible changes over millions of years. Some 250 million years ago, the continent may have been covered with forests and rivers. Instead of penguins, early relatives of the dinosaurs called Antarctica home.

The e-beam ablation has been widely used in industries, and it might provide higher overall energy efficiency of an ADR system and a higher momentum-coupling coefficient than laser ablation. However, transmitting an e-beam efficiently through the ionosphere plasma over a long distance (10 m–100 km) and focusing it to enhance its intensity above the ablation threshold of debris materials are new technical challenges that require novel methods of external actions to support the beam transmission.
As quantum computers continue to advance, many of today’s encryption systems face the risk of becoming obsolete. A powerful alternative—quantum cryptography—offers security based on the laws of physics instead of computational difficulty. But to turn quantum communication into a practical technology, researchers need compact and reliable devices that can decode fragile quantum states carried by light.
Using the Frontier supercomputer at the Department of Energy’s Oak Ridge National Laboratory, researchers from the Georgia Institute of Technology have performed the largest direct numerical simulation (DNS) of turbulence in three dimensions, attaining a record resolution of 35 trillion grid points. Tackling such a complex problem required the exascale (1 billion billion or more calculations per second) capabilities of Frontier, the world’s most powerful supercomputer for open science.
A research team led by Prof. Zhang Tianshu from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has developed a low-stress electro-optic switch based on large-aperture β-barium borate (BBO) slab crystals and integrated it into an Nd:YAG hybrid-cavity Innoslab laser system. Their study, published in Optics Express on January 13, addresses long-standing challenges in high-energy laser systems, particularly those related to switching modulation consistency and operational stability.
