New metamaterials allow researchers to create things like gamma-ray lasers.

"Since the 1960s, advancements in laser technology have aimed to enhance peak power and produce light at shorter wavelengths, with significant progress marked by the development of chirped pulse amplification in the 1980s. Current research focuses on overcoming challenges in generating coherent gamma rays, a critical step toward revolutionary applications in imaging and material studies. (Artist’s concept.)

Theoretically, gamma-ray lasers (or in this case: masers) are quite easy to make. There is a chamber on three sides of the chamber. Then the annihilation reaction like electron-positron collisions will happen in those three chambers. Then there is a material that removes all other radiation than gamma rays.

The chamber at the bottom of the gamma-ray maser sends gamma rays into the chamber, that is open at forward. Then the surrounding chambers send gamma rays into that center chamber where they form the amplifier field. The system requires other radiation except gamma rays will filter away from the radiation.

Above is the diagram of the futuristic gamma-ray laser (GRASER) or, maser. Or what the theoretical model of this system can look like.

1) The central chamber where the coherent gamma-ray beam forms.

2) Chambers where electrons and positrons annihilate. The annihilation reaction forms gamma rays. Then the material filters all other radiation than gamma rays. The maser system forms at least almost coherent gamma rays.

The new nano- and metamaterials can used to make the grid that helps to clean the gamma-ray frequencies.

Metamaterials that can change the world.

Silk and graphene are the new materials for advanced electronics. The silk and graphene metamaterials can used to protect wires. The laser system can make the channel through the silk fiber. And that allows researchers to use it to protect extremely thin wires. Another thing that this material can do is to reflect electromagnetic radiation black from the layer.

That thing helps to protect the components against electromagnetic impulses. But that kind of layer can also used as grids. The grid can transform the light into the spectrum or split it into its parts. It is theoretically possible to create metamaterials that can transform the reflecting radiation into the form of UV light.

This kind of complicated material allows the material to filter certain frequencies from the reflection. Or they can filter non-wanted EM radiation frequencies from the radiation that affects the material.

And if that kind of metamaterial is possible to create that thing makes an ultimate stealth system possible. The idea is that the grid on the layer along with some internal structures allows to transform of the reflecting light into the UV form. And in some other, more conventional solutions the metamaterial can transform the reflecting radio wave frequency. That makes objects invisible to conventional radars.

The hydrogen-burning supernovas are interesting models.

"Researchers discovered a significant magnesium anomaly in a meteorite’s dust particle, challenging current astrophysical models and suggesting new insights into hydrogen-burning supernovas. (Artist’s concept.)Credit: SciTechDaily.com" (ScitechDaily, Rare Dust Particle From Ancient Extraterrestrial Meteorite Challenges Astrophysical Models) If the star is too heavy when its fusion reaction starts, it can detonate just at that moment, when its fusion starts. If the collapsing nebula is heavy enough, it can form a black hole straight from the nebula. But if the nebula's gravity is too heavy to form the blue giant or too small it can collapse straight into a black hole . If the forming star is a little bit larger than the blue supergiants. It can explode immediately when the fusion starts. The theory of hydrogen-burning supernovas consists model of the giant stars that explode immediately after their fusion starts. When the...

The ancient galaxy mirrors the Milky Way.

"This image shows the galaxy REBELS-25 as seen by the Atacama Large Millimeter/submillimeter Array (ALMA), overlaid on an infrared image of other stars and galaxies. The infrared image was taken by ESO’s Visible and Infrared Survey Telescope for Astronomy (VISTA). In a recent study, researchers found evidence that REBELS-25 is a strongly rotating disc galaxy existing only 700 million years after the Big Bang. This makes it the most distant and earliest known Milky Way-like galaxy found to date. Credit: ALMA (ESO/NAOJ/NRAO)/L. Rowland et al./ESO/J. Dunlop et al. Ack.: CASU, CALET" (ScitechDaily, Astronomers Baffled by Ancient Galaxy That Mirrors Modern Milky Way) Researchers found the youngest Milky Way-type galaxy. The distance to the galaxy is enormous. And the light that comes from that galaxy named REBELS-25 comes from the Universe that is only 700 million years old. The distance to that galaxy is enormous about 236 billion light years. And that means it's a very dista...

Transcendence, or the ability to transcendent thinking may grow in teen's brains.

"New research has discovered that transcendent thinking, which involves analyzing the broader implications of situations, can foster brain growth in adolescents. This form of thinking enhances brain network coordination, impacting developmental milestones and future life satisfaction. The study emphasizes the need for education that encourages deep, reflective thought, underscoring the critical role of adolescents in their own brain development". (ScitechDaily, Scientists Discover That “Transcendent” Thinking May Grow Teens’ Brains) "Scientists at USC Rossier School of Education’s Center for Affective Neuroscience, Development, Learning and Education (CANDLE) have discovered that adolescents who grapple with the bigger meaning of social situations experience greater brain growth, which predicts stronger identity development and life satisfaction years later".
