Nanoscale manipulation of light leads to exciting new advancement

Posted by in categories: materials, nanotechnology

Controlling the interactions between light and matter has been a long-standing ambition for scientists seeking to develop and advance numerous technologies that are fundamental to society. With the boom of nanotechnology in recent years, the nanoscale manipulation of light has become both, a promising pathway to continue this advancement, as well as a unique challenge due to new behaviors that appear when the dimensions of structures become comparable to the wavelength of light.

Scientists in the Theoretical Nanophotonics Group at The University of New Mexico’s Department of Physics and Astronomy have made an exciting new advancement to this end, in a pioneering research effort titled “Analysis of the Limits of the Near-Field Produced by Nanoparticle Arrays,” published recently in the journal, ACS Nano, a top journal in the field of nanotechnology. The group, led by Assistant Professor Alejandro Manjavacas, studied how the optical response of periodic arrays of metallic nanostructures can be manipulated to produce in their vicinity.

The arrays they studied are composed of silver nanoparticles, tiny spheres of silver that are hundreds of times smaller than the thickness of a human hair, placed in a repeating pattern, though their results apply to nanostructures made of other materials as well. Because of the between each of the nanospheres, these systems can be used for different applications, ranging from vivid, high-resolution color printing to biosensing that could revolutionize healthcare.

Humans Have a ‘Salamander-Like’ Ability to Regenerate Damaged Body Parts, Study Finds

Posted by in category: biotech/medical

Salamanders are renowned for their regenerative capabilities, such as growing back entire limbs. We can’t pull off this biological trick, but new research highlights a previously unknown regenerative ability in humans—one held over from our evolutionary past.

Our bodies have retained the capacity to repair injured or overworked cartilage in our joints, says new research published today in Science Advances. Remarkably, the mechanics of this healing process are practically the same as what’s used by amphibians and other animals to regenerate lost limbs, according to the study.

Strange Meteorite Discovered In Siberia Contains An ‘Unnatural’ Crystal

Posted by in category: space

Despite the level of understanding and knowledge the world has about so many things, everyone is still getting excited about new discoveries and this one is no exception. A rare meteorite, which was found in Siberia, contains a crystal, or at least what appears to be a crystal. The mineral itself is quite rare as well and is also a mystery. While crystal is the term used to describe it, no one’s sure what it actually is but here’s what they know so far:

A fair few years ago now, scientists discovered a small piece of a mineral that was created shortly after the solar system, some four and half billion years ago. The mineral was brought to Earth by the Khatyrka meteorite, which landed in Eastern Siberia. Obviously, a 4 billion-year-old mineral would be incredibly interesting to almost anyone, but not so much in this case. It was still quite intriguing but not for its sheer age, as many would expect, but for its atomic structure instead.

The structure that this mineral possesses is one that has never before been found in nature, although it has been created in laboratory environments. It was referred to as a quasicrystal because from the exterior it resembles a crystal, but on the inside, it’s a whole other kettle of fish.

What is M-Theory?

Posted by in category: mathematics

It is the name of the unknown theory of everything which would combine all five Superstring theories and the Supergravity at 11 dimensions together.

The theory requires mathematical tools which have yet to be invented in order to be fully understood. The theory was proposed by Edward Witten.

The following article is somewhat technical in nature, see M-theory simplified for a less technical article.

Flight of an aeroplane with solid-state propulsion

Posted by in categories: energy, transportation

Circa 2018


Since the first aeroplane flight more than 100 years ago, aeroplanes have been propelled using moving surfaces such as propellers and turbines. Most have been powered by fossil-fuel combustion. Electroaerodynamics, in which electrical forces accelerate ions in a fluid1,2, has been proposed as an alternative method of propelling aeroplanes—without moving parts, nearly silently and without combustion emissions3,4,5,6. However, no aeroplane with such a solid-state propulsion system has yet flown. Here we demonstrate that a solid-state propulsion system can sustain powered flight, by designing and flying an electroaerodynamically propelled heavier-than-air aeroplane. We flew a fixed-wing aeroplane with a five-metre wingspan ten times and showed that it achieved steady-level flight. All batteries and power systems, including a specifically developed ultralight high-voltage (40-kilovolt) power converter, were carried on-board. We show that conventionally accepted limitations in thrust-to-power ratio and thrust density4,6,7, which were previously thought to make electroaerodynamics unfeasible as a method of aeroplane propulsion, are surmountable. We provide a proof of concept for electroaerodynamic aeroplane propulsion, opening up possibilities for aircraft and aerodynamic devices that are quieter, mechanically simpler and do not emit combustion emissions.

Laser could be used to make rain on demand

Posted by in categories: particle physics, sustainability

Circa 2010


Ultra-fast pulses from a powerful laser can create droplets of water out of thin air, according to a new study. With the right conditions and large enough droplets, the researchers say, the technique could be used to make rain on demand.

Rain forms when water condenses around tiny particles in the atmosphere. Most of the time, dust or pollen do the job, but humans have long attempted to speed the process by seeding clouds with chemicals like silver iodide. Those chemicals provide the so-called “condensation nuclei” that trigger the consolidation of water into raindrops.
