The Gaia spacecraft discovered the remains of an ancient cosmic collision in...
The investigators taking part in the global MOSAiC expedition with the Polarstern icebreaker survey have discovered fish and squid in deep water in the mid-Arctic Ocean. Suddenly four very large fish were captured at a depth of 350-400 meters. An added shock to the research study group was the fact that three of the fish...
Credit: University of Cambridge Scientists have developed self-healing, biodegradable, 3D-printed materials that could be used to develop realistic artificial hands and other soft robotics applications. The low-cost jelly-like materials, developed by scientists at the University of Cambridge, can sense strain, temperature, and humidity. Furthermore, unlike earlier self-healing robots, they can additionally partially repair themselves at room...
According to the most recent projections, sea levels along the United States coastline rise will rise quicker within the following three decades than they did in the previous 100 years, bringing more flooding to coastal cities like New York and Miami. According to a report led by the National Oceanic and Atmospheric Administration, sea levels...
The Oral Microbiome and Naturally Occurring Alveolar Bone Loss: An Experimental Investigation It is increasingly obvious that the collection of bacteria, viruses, and fungi that dwell on and within us—the human microbiome—significantly benefits our health. The microbiome as a supplement has been described as a management tool for immune cells that affect bone health in...
SpaceX's Starship carrying out test flight maneuvers. Credit: SpaceX According to a statement from Politico, Elon Musk recently provided the first big update on SpaceX's Mars-bound rocket, Starship, and its competitors are monitoring on with "a mix of admiration and fright." At his latest Starship presentation, SpaceX CEO Musk emphasized the truth that Starship would...
People like these Baka hunter-gatherers once ranged well beyond their current homeland in Central Africa.

Currently, the bones of four children buried thousands of years earlier...

However, in two current flybys of the Earth, Parker used its Wide-Field Imager, or WISPR, to image the whole nightside in wavelengths...
To study superconducting materials in their “normal,” non-superconducting state, scientists usually switch off superconductivity by exposing the material to a magnetic field (left). SLAC scientists discovered that turning off superconductivity with a flash of light (right), produces a normal state with very similar fundamental physics that is also unstable and demonstrates brief flashes of...
University of Chicago researchers discovered how to create and manipulate a quantum phenomenon known as a “domain wall” – shown in this image as the lighter line between two groups of atoms. (Image adapted and color added from experiment data). Credit: Illustration by Kai-Xuan Yao Controlled for the very first time, the quantum phenomenon might...
