HETDEX data reveal a vast ‘sea of light’ between early galaxies

Astronomers with the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) have used data from the project to make the largest, most accurate 3D map yet of the light emitted by excited hydrogen in the early universe, 9 billion to 11 billion years ago. This specific form of light, called Lyman alpha, is emitted in large quantities […]

Liquid crystal phase in antiferromagnets can be detected electrically

The best candidate for next-generation magnetic devices—technology that can power, store, sense or transport information—may be, counterintuitively, antiferromagnets. Today, the most widely used magnetic materials are ferromagnets, which exhibit permanent magnetization and therefore strongly attract each other. Their opposite, called antiferromagnetic materials, exhibit no net magnetization at all. Despite a net zero magnetic field, they […]

Life forms can planet hop on asteroid debris—and survive

Tiny life forms tucked into debris from an asteroid hit could catapult to other planets—including Earth—and survive, a new Johns Hopkins University study finds. The work demonstrates that a certain hardy bacterium easily withstands extreme pressure comparable to an ejection from Mars after an asteroid hit, as well as the inhospitable conditions it would face […]

Letting atomic simulations learn from phase diagrams

A new computational method allows modern atomic models to learn from experimental thermodynamic data, according to a University of Michigan Engineering and Université Paris-Saclay study published in Nature Communications. Leveraging a machine learning technique called score matching, the method expresses the thermodynamic free energy of atomic systems as a function of the underlying atomic interaction […]

A 690-million-kilometer journey through space ends for Australia’s SpIRIT mission

After more than 25 months of successful operations in space, the SpIRIT mission has ended, marking a major milestone for Australia’s growing space capability. Led by the University of Melbourne, in collaboration with the Italian Space Agency, the Space Industry Responsive Intelligent Thermal (SpIRIT) nanosatellite exceeded its original two-year design life.

Asteroid Ryugu samples offer new insights into early solar system magnetism

To uncover the history of our solar system, it is necessary to study the dynamic evolution of the ancient solar nebula materials. These materials interacted and coevolved with the weak but widespread magnetic field of the solar nebula, which was generated by the weakly ionized nebular gas in the protoplanetary disk. During the formation or […]

A new ‘uncertainty relation’ for quantum measurement errors

One of the most striking features of quantum physics is that certain properties cannot be measured at the same time. Every measurement may inevitably affect the object’s physical state being measured—and therefore also the outcome of any subsequent measurement. How fast something is moving, for example, can depend on whether its position was measured beforehand. […]

Reduce rust by dumping your wok twice, and other kitchen tips

When you reach the bottom of a container of milk or honey, you might be tempted to tip the container over to get that last pesky little bit out. After all, you only need another teaspoon for that recipe, and you’re sure it’s in there. From emptying jars to drying dishes, research about thin film […]

Hidden atomic dichotomy drives superconductivity in ultra-thin compound

Physicists in China have unveiled new clues to the origins of high-temperature superconductivity in an iron-based material just a single unit-cell thick. Led by Qi-Kun Xue and Lili Wang at Tsinghua University, the team’s experiments show that the effect emerges through a striking dichotomy between two atomic “sublattices” in the material—offering deeper insight into how […]

Akhenaten was known before the fifth year of his reign as Amenhotep IV. He was a Pharaoh of the Eighteenth dynasty of Egypt who ruled for 17 years and was the father of Tutankhamun. He is especially noted for abandoning […]

National report supports measurement innovation to aid commercial fusion energy and enable new plasma technologies

To operate fusion systems safely and reliably, scientists need to monitor plasma fuel conditions and measure properties like temperature and density that can affect fusion reactions. Making these measurements requires specialized sensors known as diagnostics.
