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 […]
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 […]
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.

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.

Penguin mummies dating back thousands of years have been discovered in Antarctica.
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 […]
A possible alternative to active debris removal (ADR) by laser is ablative propulsion by a remotely transmitted electron beam (e-beam). 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 […]
Quantum materials and superconductors are difficult enough to understand on their own. Unconventional superconductors, which cannot be explained within the framework of standard theory, take the enigma to an entirely new level. A typical example of unconventional superconductivity is strontium ruthenate, SRO214, the superconductive properties of which were discovered by a research team that included […]
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 […]
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 […]
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 […]
A strange alien-looking creature spreading across the world’s oceans is practically immortal. It’s Turritopsis dohrnii, the “immortal jellyfish” that can avoid death when stressed. In a manner that’s similar to a butterfly reverting to a caterpillar, the jellyfish reverts to its coral-like polyp stage. Then, it goes on to become a jellyfish again, bypassing […]
