Jan 26, 2024 (Nanowerk News) Physicists in Darmstadt are investigating ageing processes in materials. For the first time, they have measured the ticking of an internal clock in glass. When evaluating the data, they discovered a surprising phenomenon. In everyday life, we experience time as having only one direction. Who...
Using graphene to generate powerful and focused X-rays using electron waveshaping
Jan 26, 2024 (Nanowerk News) Scientists led by Nanyang Technological University, Singapore (NTU Singapore) have developed and simulated a new energy-efficient way to generate highly focused and finely controlled X-rays that are up to a thousand times more intense than those from traditional methods (Light: Science & Applications, "Free-electron crystals...
The most insane text-to-video AI system yet (w/video)
Jan 26, 2024 (Nanowerk News) Once simply science fiction fantasy, the capability to automatically generate fully formed, realistic videos from text prompts alone has inched closer to reality in recent years thanks to rapid advances in artificial intelligence. However, modeling the intricacy and fluidity of natural motion has persistently challenged...
Breakthrough in muscle regeneration uses MXene scaffolds to support tissue growth
Jan 25, 2024 (Nanowerk News) Tissue engineering, which involves the use of grafts or scaffolds to aid cell regeneration, is emerging as a key medical practice for treating volumetric muscle loss (VML), a condition where a significant amount of muscle tissue is lost beyond the body's natural regenerative capacity. To...
New method flips the script on topological physics
Jan 25, 2024 (Nanowerk News) The branch of mathematics known as topology has become a cornerstone of modern physics thanks to the remarkable – and above all reliable – properties it can impart to a material or system. Unfortunately, identifying topological systems, or even designing new ones, is generally a...
Astrophysical jet caught in a ‘speed trap’ (w/video)
Jan 25, 2024 (Nanowerk News) The science fiction author Arthur C. Clarke selected his own seven wonders of the world in a BBC television series in 1997. The only astronomical object he included was SS 433. It had attracted attention already in the late 1970s due to its X-ray emission...
Autonomous synthesis robot uses AI to speed up chemical discovery
Jan 25, 2024 (Nanowerk News) Chemists of the University of Amsterdam (UvA) have developed an autonomous chemical synthesis robot with an integrated AI-driven machine learning unit. Dubbed ‘RoboChem’, the benchtop device can outperform a human chemist in terms of speed and accuracy while also displaying a high level of ingenuity....
Harnessing cellular scaffolding for microscopic railways in nanotechnology and medicine (w/video)
Jan 25, 2024 (Nanowerk News) Princeton researchers have learned to harness the gossamer scaffolding that maintains the structure of living cells and used it to develop a nanotechnology platform. The technique eventually could lead to advances in soft robotics, new medicines, and the development of synthetic systems for high-precision biomolecular...
The curious case of zero dimensions in nanomaterials (w/video)
Jan 25, 2024 (Nanowerk Spotlight) Dimensions typically refer to the measurable extent of height, width, and depth, defining an object's presence in physical space. However, in the weird and wonderful quantum world, even the notion of dimensions gets turned upside down. Enter the concept of "zero-dimensional" nanomaterials – tiny particles...
The moon is shrinking, causing landslides and instability in lunar south pole
Jan 25, 2024 (Nanowerk News) Earth’s moon shrank more than 150 feet in circumference as its core gradually cooled over the last few hundred million years. In much the same way a grape wrinkles when it shrinks down to a raisin, the moon also develops creases as it shrinks. But...
