THE IDEA
Vanderbilt astrophysicist Karan Jani has led a series of studies that make the first case for a gravitational wave infrastructure on the surface of the moon. The experiment, dubbed Gravitational-Wave Lunar Observatory for Cosmology, uses the moon's environment and geocentric orbit to analyze mergers of black holes, neuron stars and dark matter candidates within almost 70 percent of the entire observable volume of the universe, he said.
A landmark scientific study involving marine biologists from Greece, Turkey, Cyprus, Libya, Italy, Tunisia, the UK, the US and even Malta, documenting instances where native Mediterranean species have preyed upon two highly invasive marine fish - the Pacific red lionfish and the silver-cheeked toadfish - has just been published. Prof. Alan Deidun, coordinator of the Spot the Alien Fish citizen science campaign and resident academic within the Department of Geosciences of the Faculty of Science, is a co-author of such an extensive study.
SARS-CoV-2 still poses major challenges to mankind. The frequent emergence of mutant forms makes the threat posed by the virus difficult to predict. The SARS-CoV-2 variant B.1.617 circulated in India and gave rise to the Delta variant, B.1.617.2, which is now becoming dominant in many countries. Infection researchers from the German Primate Center (DPZ) - Leibniz Institute for Primate Research in Göttingen have investigated the B.1.617 variant in detail.
A new approach to analysing the development of magnetic tangles on the Sun has led to a breakthrough in a longstanding debate about how solar energy is injected into the solar atmosphere before being released into space, causing space weather events. The first direct evidence that field lines become knotted before they emerge at the visible surface of the Sun has implications for our ability to predict the behaviour of active regions and the nature of the solar interior.
At low temperatures, certain materials lose their electrical resistance and conduct electricity without any loss - this phenomenon of superconductivity has been known since 1911, but it is still not fully understood. And that is a pity, because finding a material that would still have superconducting properties even at high temperatures would probably trigger a technological revolution.
A protein involved in making cells move offers a clue to how certain types of cancer metastasize and develop into secondary tumours, according to new research from the University of Warwick.
Scientists from Warwick Medical School have demonstrated for the first time that levels of this protein can increase and decrease the movement of a cell, including cancer cells - suggesting that they could play a role in the spread of tumours.
Classical molecular sieve membranes, with 3D microparticles and 2D nanosheets as primary building blocks, are promising in chemical separation.
Separation within such membranes relies on molecular movement and transport though their intrinsic or artificial nanopores. Since the weak connections by nature between the neighboring "bricks" usually result in intercrystalline gaps in membranes, the prevailing selectivity for classical molecular sieve membranes is moderate.
Professors at Ural Federal University (UrFU, Russia) Sergey Shcheklein and Aleksey Dubinin have developed a technology for generating energy for an electric car engine using methanol. An article describing the technology was published in the International Journal of Hydrogen Energy.
According to the latest cosmological models, large spiral galaxies such as the Milky Way grew by absorbing smaller galaxies, by a sort of galactic cannibalism. Evidence for this is given by very large structures, the tidal stellar streams, which are observed around them, which are the remains of these satellite galaxies. But the full histories of the majority of these cases are hard to study, because these flows of stars are very faint, and only the remains of the most recent mergers have been detected.
TORONTO, ON - Researchers at the University of Toronto have developed an innovative tool to aid in the investigation of how we perceive and remember visual experiences.
The new tool, referred to as a "scene wheel," will help researchers study how accurately we construct mental representations of visual experiences for later retrieval -- for example, how well an eyewitness recalls details of a crime or accident.
