A flat sheet of atoms can act as a kind of antenna that absorbs light and funnels its energy into carbon nanotubes, making them glow brightly. This advance could aid the development of tiny future light-emitting devices that will exploit quantum effects.
A novel approach in the field of Alzheimer’s research is emerging that could potentially transform how we tackle this debilitating disease. Recent studies have revealed a paradigm shift in understanding Alzheimer’s pathology, emphasizing the importance of targeting the early-stage aggregation of the pathogenic amyloid beta (A-beta) protein, specifically focusing on its soluble oligomeric form.
Over the past three decades, conventional treatments for Alzheimer’s have largely been ineffective, primarily due to their focus on combating the fibrillar form of A-beta. However, emerging research suggests that it is the soluble oligomeric form of A-beta that poses the greatest threat to neuronal health, leading to cognitive decline and neurotoxicity.
A recent breakthrough in Alzheimer’s treatment has come from the development of an antibody capable of recognizing both oligomeric and fibrillar forms of A-beta, offering newfound hope to the field. This innovative therapy has demonstrated promising results in delaying disease progression by up to 36% in individuals with early-to-mild cognitive impairment.
A nanoparticle-based therapy developed by UT Southwestern Medical Center scientists stimulated an immune pathway that eradicated tumors in mouse models of various cancer types. Their findings, published in Science Immunology, offer a new way to potentially harness the power of the body’s immune system against cancer.
Wafer-scale realization of a nanoscale magnetic tunnel junction hosting a single, ambient skyrmion enables its large readout, efficient switching, and compatibility with lateral manipulation, and thereby provides the backbone for all-electrical skyrmionic device architectures.
Optical nanoscale disk memory with petabit-level capacity is developed by extending the recording architecture to three dimensions with hundreds of layers, and exabit-level storage can be achieved by stacking the disks into arrays.
At first glance, Rabih O. Al-Kaysi’s molecular motors look like the microscopic worms you’d see in a drop of pond water. But these wriggling ribbons are not alive; they’re devices made from crystallized molecules that perform coordinated movements when exposed to light. With continued development, Al-Kaysi and colleagues say, their tiny machines could be used by physicians as drug-delivery robots or engineered into arrays that direct the flow of water around submarines.
To study nanoscale patterns in tiny electronic or photonic components, a new method based on lensless imaging allows for near-perfect high-resolution microscopy. Ptychography, a powerful form of lensless imaging, uses a scanning beam to collect scattered light for image reconstruction, facing challenges with periodic samples.
Innovative research leverages levitated optomechanics to observe quantum phenomena in larger objects, offering potential applications in quantum sensing and bridging the gap between quantum and classical mechanics.
The question of where the boundary between classical and quantum physics lies is one of the longest-standing pursuits of modern scientific research and in new research published today, scientists demonstrate a novel platform that could help us find an answer.
The laws of quantum physics govern the behavior of particles at minuscule scales, leading to phenomena such as quantum entanglement, where the properties of entangled particles become inextricably linked in ways that cannot be explained by classical physics.
Like Brian Greer has said the casimir technologies can power anything and create a free society a free utopia without the need for using any chemicals and it has been known since the 1950s in the physics community.
Previous demonstrations of the elusive Casimir force between interfaces exhibit monotonic dependence on surface displacement. Now a non-monotonic dependence of the force has been shown experimentally by exploting nanostructured surfaces.
