Scientists have successfully grown a monkey brain to be larger than its regular size by using a human brain gene, replicating that historical moment when humans and primates were set apart.
As well as showing Deimos in more detail — including the first images of its far side — insights have been gained about its makeup and structure. The new observations challenge the longstanding theory that Mars’ moons are captured asteroids, and instead point to a planetary origin. In other words, both Deimos and Phobos likely came from Mars itself, possibly ejected from a large impact.
The science team behind the Emirates Mars Mission has revealed ground-breaking imagery and data that advances our understanding of Deimos.
Deimos is one of the two small moons of Mars, the other being Phobos. Discovered in 1,877, and named after the Ancient Greek god of terror, this rocky and irregularly shaped moon has a mean radius of 6.2 km (3.9 mi) and orbits at 23,500 km (6.9 Mars radii), making it the smaller and outermost natural satellite.
Using the James Webb Space Telescope (JWST) and the Hubble Space Telescope (HST), astronomers from the University of Padua, Italy, and elsewhere have observed a metal-poor globular cluster known as Messier 92. The observations deliver crucial information regarding multiple stellar populations in this cluster. Results were published April 12 on the arXiv pre-print server.
Studies show that almost all globular clusters (GCs) exhibit star-to-star abundance variations of light elements such as helium (He), oxygen (O), nitrogen (N), carbon © and calcium (Na). This indicates self-enrichment in GCs and suggests that star clusters are composed of at least two stellar populations.
Located some 26,700 light years away in the constellation of Hercules, Messier 92 (or M92 for short) is a GC with a metallicity of just-2.31 and a mass of about 200,000 solar masses. The cluster, estimated to be 11.5 billion years old, is known to host at least two stellar generations of stars—named 1G and 2G. Previous studies have found that Messier 92 has an extended 1G sequence, which hosts about 30.4% of cluster stars, and two distinct groups of 2G stars (2GA and 2GB).
The AI is great at Russian but not so much in foreign languages.
Russia is the latest entrant to the artificial intelligence (AI) race as, mostly state-owned, Sberbank announced the launch of GigaChat, a rival to a conversational chatbot, ChatGPT. The move could heat the competition among countries looking to assume leadership positions in the technology that has taken the world by storm.
Last November, OpenAI launched ChatGPT, an AI model that can strike human-like conversations with its users. As more and more people began using ChatGPT, AI’s versatility became known.
A study reflects on how these plastic particles can increase the risk of neuroinflammation and neurodegeneration.
We have known for a while that microplastics are in our bloodstreams, making their way into our bodies through daily consumables like milk and meat. The foreign presence of micro and nano-plastic particles (MNPs) in our bodies is dangerous for obvious reasons, and they can potentially reach remote locations and penetrate living cells.
In a scary confirmation of this potentiality, a new study has found that polystyrene, a widely-used plastic found in food packaging, could be detected in the brain just two hours after ingestion.

“Delivering drugs this way could offer less systemic toxicity and is more local, comfortable, and controllable,” said Canan Dagdeviren, an associate professor in MIT’s Media Lab and the senior author of the study, in a statement.
Use terahertz frequency communication and achieve ultra-fast communication.
Researchers at the China Aerospace Science and Industry Corporation Second Institute have achieved a breakthrough in next-generation 6G communication by conducting the first real-time wireless transmission, the South China Morning Post.
6G, short for the sixth generation cellular network, is the next frontier of telecommunications which promises more reliable and faster communication than any of the existing technologies.
