Physicists have been chasing antimatter technology for more than 80 years now — driven by the promise of oppositely oriented particles that explode in a burst of energy whenever they make contact with their more common counterpart. If we could tame antimatter, those explosions could be used to power a new generation of technology, from molecular scanners to rocket engines to the so-called “annihilation laser,” a tightly concentrated energy beam fueled by annihilating positrons. But while scientists have seen recent breakthroughs in creating the particles, they still have trouble capturing and containing them.
The first impressions of using the Quest Pro’s virtual screens indicate some impressive results.
A newly discovered type of transferable DNA
DNA, or deoxyribonucleic acid, is a molecule composed of two long strands of nucleotides that coil around each other to form a double helix. It is the hereditary material in humans and almost all other organisms that carries genetic instructions for development, functioning, growth, and reproduction. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).
Physicists just reconstructed a 19th-century paradox that seems to violate the second law of thermodynamics (but really doesn’t).

Great ape animal studies have long been prohibited in Europe due to ethical concerns. An alternative to using animals in studies is the use of so-called organoids, which are three-dimensional cell structures that can be generated in the lab and are just a few millimeters in size.
These organoids can be created using pluripotent stem cells, which then subsequently develop into particular cell types like nerve cells. The study team was able to create both chimpanzee and human brain organoids by using this method.
“These brain organoids allowed us to investigate a central question concerning ARHGAP11B,” says Wieland Huttner of the Max Planck Institute of Molecular Cell Biology and Genetics, one of the three lead authors of the study.
Auroras set off spectacular light shows in the night sky, but they are also illuminating another reason the ozone layer is being eaten away.
Although humans are to blame for much of the ozone layer’s depletion, observations of a type of aurora known as an isolated proton aurora have revealed a cause of ozone depletion that comes from space: Charged particles in plasma belched out by solar flares and coronal mass ejections also keep gnawing at the ozone layer. Before now, the influence of these particles were only vaguely known.
Summary: A new 3D electrode array allows researchers to map the activity and location of up to 1 million synaptic links in a living brain.

It’s a mystery how human thoughts and dreams emerge from electrical pulses in the brain’s estimated 100 trillion synapses, and Rice University neuroengineer Chong Xie dreams of changing that by creating a system that can record all the electrical activity in a living brain.
The collapse of Arecibo’s radio telescope was a devastating blow to the radio astronomy community. Issues began in 2017 for the nearly 55-year-old telescope when Hurricane Maria tore through Puerto Rico, shearing off one of the 29-meter (96-foot) antennas that was suspended above the telescope’s 305-meter (1,000-foot) dish, with falling debris puncturing the dish in several places.
In early 2020, earthquakes temporarily closed the observatory for safety reasons; then a succession of cable failures ultimately led to the December 2020 collapse of the 900-ton instrument platform suspended above the observatory, which crashed down on the iconic telescope’s giant dish. This collapse officially ended any possible hopes of refurbishing the famous observatory.
Since then, many have called for the telescope to be rebuilt or for building an even better replacement telescope at the site. Instead, the NSF wants Arecibo to serve as a hub for STEM education and outreach.
