"Overall, we think that being musical could be a way of harnessing the brain's agility and resilience, known as cognitive reserve." Based on the results obtained by the researchers, light can be slowed down by more than 10,000 times in this system. At the same time, the light loss is reduced by more than five times compared with other comparable methods. Key to the new approach is the way that the tiniest building blocks of the metasurface – known as meta-atoms – are ... According to some studies, they occur in up to 2% of cases. If a hole or tear of the posterior capsule is encountered during cataract surgery, the clear gel in the vitreous … For The First Time, Physicists Measure Antimatter Falling in Gravity. As far as gravity is concerned, both matter and its charge-flipped 'mirror' twin, antimatter, deserve a big, warm hug. A recent experiment by international Antihydrogen Laser Physics Apparatus ( ALPHA) collaboration achieved the first direct measurement of free-falling ... Groundbreaking New Response to Cardiac Arrest Expected to Save Lives. Health 12 February 2024. By Vinuli Withanarachchie et al., The Conversation. (Peter Dazeley/Getty Images) As of January this year, Aotearoa New Zealand became just the second country (after Canada) to adopt a groundbreaking new procedure for patients …Earth Has Received a Message Laser-Beamed From 10 Million Miles Away. Eventually, we're going to want to expand the World Wide Web across the galaxy, and NASA just demonstrated a key piece of tech that could help, beaming messages via laser across a distance of almost 16 million kilometers or 10 million miles. That's about 40 …The ghost, at long last, is actually in the machine. Earlier this year, for the first time, scientists detected neutrinos created in a particle collider.Those abundant yet enigmatic subatomic particles are so removed from the ... A new kind of black hole analog could tell us a thing or two about an elusive radiation theoretically emitted by the real thing.. Using a chain of atoms in single-file to simulate the event horizon of a black hole, a team of physicists has observed the equivalent of what we call Hawking radiation – particles born from disturbances in the quantum fluctuations caused by the black hole's break ...

The gamma-ray burst GRB 221009A shattered records as it flared in the darkness of space in October 2022 some 2.4 billion light-years from Earth, its light blazing with up to 18 teraelectronvolts of energy in what is regarded as the brightest space explosion ever recorded. Now, scientists have determined that the explosion was so powerful that ...In a galaxy at the center of a massive cluster named Abell 1201, some 2.7 billion light-years away, lurks a cosmic colossus. Not content with being supermassive, the monster is an ultra massive black hole, clocking in at around 32.7 billion times the mass of the Sun. The new figure exceeds previous estimates by at least 7 billion solar masses ...The gamma-ray burst GRB 221009A shattered records as it flared in the darkness of space in October 2022 some 2.4 billion light-years from Earth, its light blazing with up to 18 teraelectronvolts of energy in what is regarded as the brightest space explosion ever recorded. Now, scientists have determined that the explosion was so powerful that ... The research has been published in Communications Biology. An earlier version of this article was published in November 2022. A study of 26 years' worth of wolf behavioral data, and an analysis of the blood of 229 wolves, has shown that infection with the parasite Toxoplasma gondii makes wolves 46 times more likely to become a pack leader. After cutting off bits of the algae the researchers saw differences in intensity of green pigmentation at its regeneration sites. At night these spots were relatively transparent, whereas during the day they became a solid, opaque green. Growth of a Giant Single Cell is Intertwined with Daily Self-Rhythms.

Physics 03 December 2023. By Mike McRae. (Dario Truco/Getty Images) A newly discovered trade-off in the way time-keeping devices operate on a fundamental level could set a hard limit on the performance of large-scale quantum computers, according to researchers ... May 5, 2023 · Curiously, in 2011 a team led by NASA Marshall planetary scientist Renee Weber found a similar result using what were then state-of-the-art seismological techniques on Apollo data to study the lunar core. They found evidence of a solid inner core with a radius of about 240 kilometers, and a density about 8,000 kilograms per cubic meter. Scientists have discovered that one material with a formula found in nature is capable of superconducting at low temperatures without using the typical quantum trickery, making it the first unconventional superconductor of its kind. Superconductors are fascinating and also hugely useful, because they conduct electricity without energy loss.The Frontier supercomputer, currently the most powerful computer in the world, would take a little over 47 years to crunch the same numbers, the researchers suggest, whereas the Sycamore quantum computer managed it in mere seconds. A group including Google engineers did something similar in 2019, with 53 qubits.After cutting off bits of the algae the researchers saw differences in intensity of green pigmentation at its regeneration sites.

"We found that fluorescence is widespread in mammalian taxa", the researchers write. "Areas of fluorescence included white and light fur, quills, whiskers, claws, teeth and some naked skin." The only species of mammal that …Mar 14, 2024 · Earth Received a Message Laser-Beamed From 10 Million Miles Away in NASA Test. Eventually, we're going to want to expand the World Wide Web across the galaxy, and NASA recently demonstrated a key piece of tech that could help, beaming messages via laser across a distance of almost 16 million kilometers (10 million miles). Scientists have known about these plant defenses since the 1980s, detecting them in over 80 plant species since then. Now, a team of Japanese researchers has deployed real-time imaging techniques to reveal how plants receive and respond to these aerial alarms. This was a big gap in our understanding of plant chatter: we knew how plants send ...The 13-sided polygon, which 64-year-old Smith called "the hat", is the first single shape ever found that can completely cover an infinitely large flat surface without ever repeating the same pattern. That makes it the first "einstein" – named after the German for "one stone" (ein stein), not the famed physicist – and solves a problem posed ...Essentially, it stops the enzyme from attacking healthy cells by gently ushering it out of the picture as these cells grow. Part of the signaling that controls the immune …The set-up of lasers, lenses and mirrors used in the lab experiments. ( Zhu et al., Physical Review Letters, 2023) "We demonstrated that the way you charge a battery made up of quantum particles could drastically impact its performance," says Chen.
