Healing Power of Light: Biomimetic Materials Pulsed With Low-Energy Blue Light Can Reshape Damaged Corneas

Posted by in categories: energy, materials

A new study reveals that biomimetic materials, when pulsed with low-energy blue light, can reshape damaged corneas, including increasing their thickness. The findings have the potential to affect millions of people.

A team of University of Ottawa researchers and their collaborators have uncovered the immense potential of an injectable biomaterial that is triggered by low-energy blue light pulses for immediate repair of the eye’s domed outer layer.

Following a design approach guided by biomimicry—innovation that takes inspiration from nature—the multidisciplinary researchers’ compelling results show that a novel light-activated material can be used to effectively reshape and thicken damaged corneal tissue, promoting healing and recovery.

New algorithm ensnares its first ‘potentially hazardous’ asteroid

Posted by in categories: asteroid/comet impacts, existential risks, information science

An asteroid discovery algorithm—designed to uncover near-Earth asteroids for the Vera C. Rubin Observatory’s upcoming 10-year survey of the night sky—has identified its first “potentially hazardous” asteroid, a term for space rocks in Earth’s vicinity that scientists like to keep an eye on.

The roughly 600-foot-long asteroid, designated 2022 SF289, was discovered during a test drive of the algorithm with the ATLAS survey in Hawaii. Finding 2022 SF289, which poses no risk to Earth for the foreseeable future, confirms that the next-generation algorithm, known as HelioLinc3D, can identify near-Earth asteroids with fewer and more dispersed observations than required by today’s methods.

New clues to the source of the universe’s magnetic fields

Posted by in category: space

It isn’t just your refrigerator that has magnets on it. The Earth, the stars, galaxies, and the space between galaxies are all magnetized, too. The more places scientists have looked for magnetic fields across the universe, the more they’ve found them. But the question of why that is the case and where those magnetic fields originate from has remained a mystery and a subject of ongoing scientific inquiry.

Published in the journal Physical Review Letters, a new paper by Columbia researchers offers insight into the source of these fields. The team used models to show that magnetic fields may spontaneously arise in turbulent plasma. Plasma is a kind of matter often found in ultra-hot environments like that near the surface of the sun, but plasma is also scattered across the in low-density environments, like the expansive between ; the team’s research focused on those low-density environments.

Their simulations showed that, in addition to generating new magnetic fields, the turbulence of those plasmas can also amplify magnetic fields once they’ve been generated, which helps explain how magnetic fields that originate on small scales can sometimes eventually reach to stretch across vast distances.

Launch Roundup: SpaceX to launch Galaxy 37; China to launch FY-3F

Posted by in categories: climatology, satellites

Breaking into the 31st week of 2023, from July 31 to Aug. 6, not much is held in store in terms of launches. Up first this week — following an aborted launch attempt last week — Rocket Lab will launch Capella Space’s Acadia satellite to a mid-inclination low-earth orbit. Later, a momentous flight will take place, when the last Antares 230+ will fly to low-Earth orbit (LEO) during the NG-19 resupply mission to the International Space Station (ISS).

Following slightly more than a day later, a Chang Zheng 4C carrying the Fengyun-3F meteorological satellite will take to the skies from Jiuquan, China. Shortly after that, it will be the turn of a Falcon 9 transporting Maxar-built Galaxy 37 inside its fairing. It will be deployed into a geostationary transfer orbit (GTO), with the satellite reaching a geostationary orbit (GEO) by itself.

‘Organoid Intelligence’ — how mini-brains could replace AI for supercomputing

Posted by in categories: robotics/AI, supercomputing

While Artificial Intelligence has the ability to crunch huge amounts of data in a short span of time, it still falls behind when it comes to finding an energy-efficient way to make complex decisions. Researchers from John Hopkins University in the US are now proposing that 3D cell structures that mimic brain functions can be used to create biocomputers.

When electrons slowly vanish during cooling: Researchers observe an effect unique to the quantum world

Posted by in category: quantum physics

Many substances change their properties when they are cooled below a certain critical temperature. Such a phase transition occurs, for example, when water freezes. However, in certain metals there are phase transitions that do not exist in the macrocosm. They arise because of the special laws of quantum mechanics that apply in the realm of nature’s smallest building blocks.

It is thought that the concept of electrons as carriers of quantized no longer applies near these exotic transitions. Researchers at the University of Bonn and ETH Zurich have now found a way to prove this directly. Their findings allow new insights into the exotic world of quantum physics. The publication has now been released in the journal Nature Physics.

If you below zero degrees Celsius, it solidifies into ice. In the process, it abruptly changes its properties. As ice, for example, it has a much lower density than in a liquid state—which is why icebergs float. In physics, this is referred to as a phase transition.
