Shockwaves through the “cosmic web” spotted Astronomers have detected the first evidence of shockwaves in intergalactic magnetic fields running throughout the cosmic web. Researchers combined data from four radio wave detection sites to identify the waves resulting from merging matter in the network of filaments that weave galaxies together. Full Story: Space First wiring map […]
Greenhouse gases act like a layer of window glass in the atmosphere: They prevent heat from being radiated from the Earth’s surface into space. Methane does that 28 times as effectively as carbon dioxide – it is (to stay in the picture) a kind of invisible double glazing. Over the past 200 years, the concentration […]
Phytoplankton increasingly blooming on coastlines Phytoplankton blooms increased around 13% in extent and occurred 59% more often along global coastlines between 2003 and 2020. The microscopic algae are both beneficial to fisheries and potentially dangerous for marine animals in large amounts, researchers note, and the increase in phytoplankton blooms is caused by warmer ocean temperatures […]
Atomic nuclei take a range of shapes, from spherical (like a basketball) to deformed (like an American football). Spherical nuclei are often described by the motion of a small fraction of the protons and neutrons, while deformed nuclei tend to rotate as a collective whole. A third kind of motion has been proposed since the […]
Ancient fish that ate humans’ ancestors discovered Researchers have excavated the remains of a giant ancient bony fish species with fangs from about 350 million years ago in what is now South Africa. The findings, published in the journal PLOS One, indicate that the Hyneria udlezinye species measured up to 2.7 meters long and likely […]
Gas clouds in the Cygnus X Region, a region where stars form, are composed of a dense core of molecular hydrogen (H2) and an atomic shell. These ensembles of clouds interact with each other dynamically in order to quickly form new stars. The Cygnus X region is a vast luminous cloud of gas and dust […]
Analysis of cell villages yields insight into Zika infections Studying cell villages, or samples from different donors in a shared environment, is an effective method “to identify genes and genetic variants that change a cell’s phenotype.” Scientists used the method along with the Dropulation and Census-seq algorithms to assess genetic variation in cell villages and […]
Lithium-ion batteries have remained unrivalled in terms of overall performance for several applications, as evidenced by their widespread use in everything from portable electronics to cellular base stations. However, they suffer from some important disadvantages that are difficult to ignore. For one, lithium is rather expensive, and the fact that it is being mined at […]
Astronomers puzzled by distant planet’s ring Astronomers have discovered a ring around the distant minor planet Quaoar that defies scientific understanding of how and where rings are formed. Quaoar’s ring exists in a location outside of where scientists believe particles should remain in a disk formation, prompting questions about the nature of celestial rings. Full […]
Gel-like materials that can be injected into the body hold great potential to heal injured tissues or manufacture entirely new tissues. Many researchers are working to develop these hydrogels for biomedical uses, but so far very few have made it into the clinic. To help guide in the development of such materials, which are made […]
