NASA has issued a warning regarding a satellite expected to deorbit on April 19, posing a potential risk of harm on Earth. Here’s what we know.
Update: NASA’s retired RHESSI re-entered Earth’s atmosphere at 8:21 p.m. EDT on Wednesday, April 19. The large flash seen over Kyiv, Ukraine, on April 19 was not the deorbiting satellite.
Some people might be regretting throwing their old cassette tapes.
In the music world, vinyl records get a lot of attention when it comes to physical media. Sales for vinyl records have been on the rise for years, and now the same thing is starting to happen with cassette tapes.
The resurgence of vinyl records has been so strong that it’s not really even a “trend” anymore. In 2021, people spent more on vinyl than CDs for the first time since 1986. Cassette tape sales, on the other hand, have been very low for a long time. However, in the last five years, things are changing.

Donald Hoffman interview on spacetime, consciousness, and how biological fitness conceals reality. We discuss Nima Arkani-Hamed’s Amplituhedron, decorated permutations, evolution, and the unlimited intelligence.
The Amplituhedron is a static, monolithic, geometric object with many dimensions. Its volume codes for amplitudes of particle interactions & its structure codes for locality and unitarity. Decorated permutations are the deepest core from which the Amplituhedron gets its structure. There are no dynamics, they are monoliths as in 2001: A Space Odyssey.

But we expect that it’s in that first tiny fraction of a second that the key features of our universe were imprinted.
The conditions of the universe can be described through its “fundamental constants”—fixed quantities in nature, such as the gravitational constant (called G) or the speed of light (called C). There are about 30 of these representing the sizes and strengths of parameters such as particle masses, forces, or the universe’s expansion. But our theories don’t explain what values these constants should have. Instead, we have to measure them and plug their values into our equations to accurately describe nature.
Scientists in Britain have finally solved one of the greatest mysteries of life: how chromosomes get their X shape. Chromosomes, discovered in the late 1800s, are DNA molecules which contain the genetic material of an organism.
All chromosomes, without exception, either go through or end up with an X shape before the cells of an organism divide.
But it was always a mystery how they are X-shaped. While Biology students across the world study that chromosomes get their shape during cell division, the exact reason behind their X shape was not known.
Experts from Charles River and Valo Health describe how artificial intelligence will change the drug discovery landscape.
Now, we live in a time in which AI research and technology is advancing exponentially. In the coming years, AI — and ultimately AGI — has the potential to drive one of the greatest social, economic and scientific transformations in history.
That’s why today Sundar is announcing that DeepMind and the Brain team from Google Research will be joining forces as a single, focused unit called Google DeepMind. Combining our talents and efforts will accelerate our progress towards a world in which AI helps solve the biggest challenges facing humanity, and I’m incredibly excited to be leading this unit and working with all of you to build it. Together, in close collaboration with our fantastic colleagues across the Google Product Areas, we have a real opportunity to deliver AI research and products that dramatically improve the lives of billions of people, transform industries, advance science, and serve diverse communities.
By creating Google DeepMind, I believe we can get to that future faster. Building ever more capable and general AI, safely and responsibly, demands that we solve some of the hardest scientific and engineering challenges of our time. For that, we need to work with greater speed, stronger collaboration and execution, and to simplify the way we make decisions to focus on achieving the biggest impact.
DGIST Professor Yoonkyu Lee’s research team used intense light on the surface of a copper wire to synthesize graphene, thereby increasing the production rate and lowering the production cost of the high-quality transparent-flexible electrode materials and consequently enabling its mass production. The results were published in the February 23 issue of Nano Energy.
This technology is applicable to various 2D materials, and its applicability can be extended to the synthesis of various metal-2D material nanowires.
The research team used copper-graphene nanowires to implement high-performance transparent-flexible electronic devices such as transparent-flexible electrodes, transparent supercapacitors and transparent heaters and to thereby demonstrate the commercial viability of this material.
Silver, gold and copper nanowires are leading contenders for next-generation nanoscale devices, however greater understanding of how they work and improved production methods are needed before they can be widely used, explains a recent review in the journal Science and Technology of Advanced Materials.
“Metal nanowires are used for numerous applications, but our understanding of their mechanical properties remains elusive,” says Nurul Akmal Che Lah, engineer at Universiti Malaysia Pahang.
Lah and colleague Sonia Trigueros at the University of Oxford reviewed methods for synthesising and analysing silver, gold and copper nanowires for molecular-based electronics.
