Strongly correlated systems are systems made of particles that strongly interact with one another, to such an extent that their individual behavior depends on the behavior of all other particles in the system. In states that are far from equilibrium, these systems can sometimes give rise to fascinating and unexpected physical phenomena, such as many-body localization.

Stanford University researchers have developed a computational method for identifying where cells are situated in a sample when capturing spatial transcriptomics. The method combines data from spatial transcriptions and a reference single-cell RNA atlas to create modeling outputs. The resulting models can be used to view cellular substructures, identify colocalization patterns and analyze differen

But researchers have now created soft robots that can seamlessly shift from walking to swimming, for example, or crawling to rolling using a bistable actuator made of 3D-printed soft rubber containing shape-memory alloy springs that re

Scientists succeeded in directly observing how LECs — which are attracting attention as one of the post-organic LEDs — change their electronic state over time during field emission by measuring their optical absorption via lamp light irradiation for the first time. This research method can be applied to all light-emitting devices, including not only LECs but also organic LEDs. This method is exp

A Wolf-Rayet star is a rare prelude to the famous final act of a massive star: the supernova. As one of its first observations in 2022, the NASA/ESA/CSA James Webb Space Telescope captured the Wolf-Rayet star WR 124 in unprecedented detail. A distinctive halo of gas and dust frames the star and glows in the infrared light detected by Webb, displaying knotty structure and a history of episodic ejec

COVID is not yet under control. Despite a bevy of vaccines, monoclonal antibodies, and antivirals, the virus continues to mutate and elude us. One solution that scientists have been exploring since the early days of the pandemic may come in the form of tiny antibodies derived from llamas, which target various parts of the SARS-CoV-2 spike protein.

The question will be simple but perpetual: Person or machine? Every encounter with language, other than in the flesh, will now bring with it that small, consuming test. For some—teachers, professors, journalists—the question of humanity will be urgent and essential. Who made these words? For what purpose? For those who operate in the large bureaucratic apparatus of boilerplate—copywriters, lawyer

Almost 5 miles above sea level in the Himalayan mountains, the rocky dip between Mount Everest and its sister peak, Lhotse, lies windswept, free of snow. It is here at the South Col where hundreds of adventurers pitch their final camp each year before attempting to scale the world's tallest peak from the southeastern side.

University of Minnesota students conducted crucial genome sequencing for the newly discovered soybean gall midge—a pest that is threatening the soybean crop, one of the most widely cultivated and consumed throughout the world. This small fly has been found in major soybean-producing states in the Midwest, including Minnesota, Iowa, Nebraska, South Dakota and Missouri.

The existing 3D-printed scaffolds commonly possess a thick feature size of hundreds of micrometers, which is too large for most cells (10–20 μm) to attach and proliferate for promoting tissue regeneration. Researchers from Xi'an Jiaotong University have developed a novel hybrid manufacturing technique for the fabrication of composite scaffolds with 3D-printed macroscale frameworks and aligned nano

The universe is peppered with galaxies, which, on large scales, exhibit a filamentary pattern, referred to as the cosmic web. This heterogeneous distribution of cosmic material is in some ways like blueberries in a muffin where material clusters in certain areas but may be lacking in others.

Every second the Earth is bombarded by vast amounts of cosmic rays—invisible sub-atomic particles that originate from things like the sun and supernova explosions. These high-energy, far-traveled cosmic rays collide with atoms as they enter Earth's atmosphere and set off cascades of secondary cosmic rays.
