Researchers in the UK have developed a way to coax microscopic particles and droplets into precise patterns by harnessing the power of sound in air. The implications for printing, especially in the fields of medicine and electronics, are far-reaching.

The scientists from the Universities of Bath and Bristol have shown that it’s possible to create precise, pre-determined patterns on surfaces from aerosol droplets or particles, using computer-controlled ultrasound. A paper describing the entirely new technique, called ‘sonolithography’, is published in Advanced Materials Technologies.

Professor Mike Fraser from the Department of Computer Science at the University of Bath, explained: “The power of ultrasound has already been shown to levitate small particles. We are excited to have hugely expanded the range of applications by patterning dense clouds of material in air at scale and being able to algorithmically control how the material settles into shapes.”

Recently published neuroimaging research provides evidence that the directional connectivity between several brain regions plays an important role in emotional processing abilities.

Although interest in emotional intelligence has been steadily growing since the 1990s, the underlying neural mechanisms behind it have yet to be clearly established. The new study, which appears in NeuroImage, is part of a process to begin to fill in this gap in scientific knowledge.

“Emotional intelligence is one of the least studied topics, especially in conjunction with cutting-edge computational neuroimaging techniques,” explained lead researcher Sahil Bajaj, the director of the Multimodal Clinical Neuroimaging Laboratory at Boys Town National Research Hospital.

China laid out seven “frontier” technologies in its 14th Five Year Plan. These are areas that China will focus research on and include semiconductors and brain-computer fusion.

However, such work is already underway in the U.S. at Elon Musk’s company Neuralink. Musk is working on implantable brain-chip interfaces to connect humans and computers.

There is considerable debate over whether plants are conscious and this, indeed, is an important question. Here I look at developments in neuroscience, physics and mathematics that may impact on this question. Two major concomitants of consciousness in animals are microtubule function and electrical gamma wave synchrony. Both these factors may also play a role in plant consciousness. I show that plants possess aperiodic quasicrystal structures composed of ribosomes that may enable quantum computing, which has been suggested to lie at the core of animal consciousness. Finally I look at whether a microtubule fractal suggests that electric current plays a part in conventional neurocomputing processes in plants.

SN10 Successful Flight and soft Landing, 🚀15min later methane leak goes boom 💥😅STARSHIP SN10 10KM FLIGHT Links: SpaceX Official: www.SpaceX.comSpaceX YouTu… See More.


As early as Wednesday, March 3, the SpaceX team will attempt a high-altitude flight test of Starship serial number 10 (SN10) – our third high-altitude suborbital flight test of a Starship prototype from SpaceX’s site in Cameron County, Texas. Similar to the high-altitude flight tests of Starship SN8 and SN9, SN10 will be powered through ascent by three Raptor engines, each shutting down in sequence prior to the vehicle reaching apogee – approximately 10 km in altitude. SN10 will perform a propellant transition to the internal header tanks, which hold landing propellant, before reorienting itself for reentry and a controlled aerodynamic descent.

The Starship prototype will descend under active aerodynamic control, accomplished by independent movement of two forward and two aft flaps on the vehicle. All four flaps are actuated by an onboard flight computer to control Starship’s attitude during flight and enable precise landing at the intended location. SN10’s Raptor engines will then reignite as the vehicle attempts a landing flip maneuver immediately before touching down on the landing pad adjacent to the launch mount.

Without electronics and photonics, there would be no computers, smartphones, sensors, or information and communication technologies. In the coming years, the new field of phononics may further expand these options. That field is concerned with understanding and controlling lattice vibrations (phonons) in solids. In order to realize phononic devices, however, lattice vibrations have to be controlled as precisely as commonly realized in the case of electrons or photons.
