In 1998, a paper linking childhood vaccines with autism was published in the journal, The Lancet, only to be retracted in 2010 when the science was debunked.
Most people agree that the spread of online misinformation is a serious problem. But there is much less consensus on what to do about it.
Strong field quantum optics is a rapidly emerging research topic, which merges elements of non-linear photoemission rooted in strong field physics with the well-established realm of quantum optics. While the distribution of light particles (i.e., photons) has been widely documented both in classical and non-classical light sources, the impact of such distributions on photoemission processes remains poorly understood.
We’re closer than ever to being able to upload our minds and become “digitally immortal.” But should we?
Experiments generate quantum entanglement over optical fibres across three real cities, marking progress towards networks that could have revolutionary applications.
Humans are arguably the most peculiar species that has ever existed.
Acknowledging the unique aspects of human evolution underscores our extraordinary place in the grander scheme—a species with one foot in the natural world and the other in a realm of conscious self-awareness and purpose. This dual heritage suggests„.
In a May 15 paper released in the journal Physical Review Letters, Virginia Tech physicists revealed a microscopic phenomenon that could greatly improve the performance of soft devices, such as agile flexible robots or microscopic capsules for drug delivery.
The paper, written by doctoral candidate Chinmay Katke, assistant professor C. Nadir Kaplan, and co-author Peter A. Korevaar from Radboud University in the Netherlands, proposes a new physical mechanism that could speed up the expansion and contraction of hydrogels. For one thing, this opens up the possibility for hydrogels to replace rubber-based materials used to make flexible robots—enabling these fabricated materials to perhaps move with a speed and dexterity close to that of human hands.
Soft robots are already being used in manufacturing, where a hand-like device is programmed to grab an item from a conveyer belt—picture a hot dog or piece of soap—and place it in a container to be packaged. But the ones in use now lean on hydraulics or pneumatics to change the shape of the “hand” to pick up the item.
A “flying car” took to the air in Tokyo for the first time on Friday during an international event showcasing cutting-edge technology.
About 500 spectators applauded as the vehicle hovered around 10 meters off the ground in a parking lot outside the Tokyo Big Sight convention center in the capital’s Koto Ward for SusHi Tech Tokyo 2024.
Flying vehicles are expected to become part of the next generation of human transportation and will be effective in dealing with traffic congestion and delivering supplies to disaster areas, the Tokyo metropolitan government and other organizers said.
Quantum theorists at the University of British Columbia have proposed a new approach to studying stacking ferroelectricity—spontaneous electric polarization—in layered, two-dimensional lab-grown materials.
