We propose a self-supervised facial action transformer that enables multilingual lip synchronization in humanoid robots.
13 years ago, I walked into Dr. Stuart Hameroff’s operating room with a camera, a microphone, and a single stubborn question:
Is consciousness computation?
Hameroff, an anesthesiologist and professor at the University of Arizona, and co-author with Sir Roger Penrose of the Orch OR theory, said no.
Emphatically. Unfashionably. Against the entire weight of mainstream neuroscience and Silicon Valley orthodoxy.
At the GF2045 conference, where I first met him, Ray Kurzweil went out of his way to declare Orch OR “totally wrong.” Others called it speculative. Untestable. Unscientific.
Today, in the age of large language models, that argument is no longer a niche dispute among philosophers and physicists. It is the decisive question of our century.
The course covers the key architecture designs of modern Transformers that power today’s generative AI revolution.
Imagine a car whose windows and sunroof can help top up its battery while parked under the sun, or a pair of smart glasses whose lenses can harvest light to power built-in electronics.
Such applications could become more feasible with a new type of ultrathin transparent solar cell developed by scientists from Nanyang Technological University, Singapore (NTU Singapore).
Led by Associate Professor Annalisa Bruno, the NTU researchers created perovskite solar cells that are about 10,000 times thinner than a strand of human hair and around 50 times thinner than conventional perovskite solar cells.
The task of gently transporting a microscopic particle from one point to another along a winding path, and then bringing it back using nothing more than a single, compact chip is a challenge we set out to address in our new study, now published in Nature Communications.
Optical forces arising from momentum exchange during light–matter interactions have become indispensable tools in biophysics, soft matter science and micro-and nanofabrication. Among these, optical conveyors—capable of generating stable, directional optical flows—enable nanoparticle transport along predefined trajectories, offering unique advantages for drug delivery, cell sorting, and lab-on-a-chip systems. However, conventional platforms often rely on spatial light modulators to produce dynamic holograms. Such systems are bulky, constrained by limited pixel size and count, and difficult to integrate—factors that severely impede practical deployment.
Metasurfaces have recently opened new pathways for miniaturizing optical manipulation devices, thanks to their subwavelength field-shaping capabilities. Yet, most existing metasurface-based schemes still depend on radially or azimuthally uniform phase gradients, which confine the resulting optical flow to closed loops (vortex rings) due to the intrinsic geometry of vortex fields.
Earth is flying through the radioactive ashes of an ancient exploded star, and Antarctic ice preserved the evidence.
Scientists have found new evidence that Earth is moving through a cloud of ancient supernova debris left behind by a long ago stellar explosion. By examining Antarctic ice tens of thousands of years old, researchers detected iron-60, a rare radioactive isotope created when massive stars explode. The findings suggest that the Local Interstellar Cloud surrounding our Solar System contains lingering material from an ancient supernova. The study was led by an international team from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and published in Physical Review Letters.
Ancient Supernova Material Reaching Earth.
NASA’s Curiosity rover has identified a wide range of organic molecules on Mars, including compounds that scientists consider key ingredients for the origin of life on Earth.
The discovery comes from a chemical experiment carried out on another planet for the first time. Results show that the Martian surface is capable of preserving molecules that could act as potential signs of ancient life. However, the experiment cannot determine whether these organic compounds came from past life on Mars, natural geological processes, or meteorites that struck the planet.
To confirm any true evidence of past life, scientists would need to bring Martian rock samples back to Earth for detailed study.
