What if the secret to slowing down aging was hiding in our brains? A groundbreaking study by researchers at the Allen Institute for Brain Science in Seattle, published in Nature in January 2025, may have uncovered some exciting clues. Using cutting-edge technology, the team analyzed over 1.2 million brain cells from young and aged mice to understand how they change with time. They found that certain cells become inflamed, while others lose critical functions, and all eyes are now on the hypothalamus as a key player in the aging process. These findings deepen our understanding of aging and could pave the way for treatments that keep our brains younger for longer.

Early Formation of Life’s Building Blocks

A groundbreaking study published in Nature Astronomy has revealed that amino acids, essential for life, can form in dark interstellar clouds long before stars and planets emerge. Glycine, the simplest amino acid, was shown to form on the surface of icy dust grains in cold, energy-deprived environments through a process called “dark chemistry.” These findings challenge the long-standing belief that UV radiation was required to create glycine, significantly expanding our understanding of how life’s precursors emerge in space.

Astronomers using the James Webb Space Telescope have used a distortion in space to reveal over 40 individual stars in a galaxy 6.5 billion light-years from the Milky Way—halfway back to the beginning of the universe. It’s the largest number of individual stars ever detected in the distant universe.

The unique image, which takes advantage of JWST’s high-resolution optics, was only possible because the light from 44 stars in a distant galaxy was magnified by a massive cluster of galaxies in front of it called Abell 370.

This technique, called gravitational lensing—also known as an “Einstein ring” because it was predicted by the famous scientist Albert Einstein—works when the gravitational field of a foreground object distorts the space around it. Light is bent from an object behind it into circular rings or arcs, both revealing the existence of something in the background and, crucially, magnifying it by factors of hundreds or even thousands. In this case, an arc was visible, dubbed the “Dragon Arc.”

Researchers at the University of Virginia are using advanced simulations to study electron behavior in electric propulsion thrusters.

Cape Canaveral (AFP) Jan 5, 2025 — Amazon founder Jeff Bezos’s company Blue Origin is poised to launch its first orbital rocket next week, marking a pivotal moment in the commercial space race currently dominated by Elon Musk’s SpaceX.

The billionaire SpaceX CEO tasked scientists with designing domes and researching procreation with an eye toward colonizing the Red Planet.

Currently, 5,788 exoplanets have been confirmed in 4,326 star systems, while thousands more candidates await confirmation. So far, the vast majority of these planets have been gas giants (3,826) or Super-Earths (1,735), while only 210 have been “Earth-like”—meaning rocky planets similar in size and mass to Earth.

What’s more, the majority of these planets have been discovered orbiting within M-type (red dwarf) star systems, while only a few have been found orbiting sun-like stars. Nevertheless, no Earth-like planets orbiting within a sun-like star’s habitable zone (HZ) have been discovered so far.

This is largely due to the limitations of existing observatories, which have been unable to resolve Earth-sized planets with longer orbital periods (200 to 500 days). This is where next-generation instruments like the ESA’s PLAnetary Transits and Oscillations of stars (PLATO) mission come into play.
