NASA's Artemis II Live Mission Coverage (Official Broadcast)
By Nasa, Live on youtube
---------------------
This feed will provide continuous coverage of Artemis II mission activities with live commentary, beginning with tanking of the SLS (Space Launch System) rocket at NASA's Kennedy Space Center and concluding with the recovery of the Orion Integrity spacecraft after splashdown.

Live coverage of Artemis II's launch and lunar flyby, as well as daily mission briefings, will also stream on this feed. These events will additionally be carried as standalone streams on NASA's YouTube channel and elsewhere.

Four astronauts — three from NASA and one from the CSA (Canadian Space Agency) — make up the Artemis II crew:
- NASA astronaut Reid Wiseman, Artemis II commander
- NASA astronaut Victor Glover, Artemis II pilot
- NASA astronaut Christina Koch, Artemis II mission specialist
- Canadian Space Agency (CSA) astronaut Jeremy Hansen, Artemis II mission specialist

- Canadian Space Agency (CSA) astronaut Jeremy Hansen, Artemis II mission specialist

After launching into space atop SLS, the crew will journey around the Moon and back in their Orion spacecraft on an approximately 10-day mission. Artemis II will be the first crewed flight test of SLS and Orion, testing the technologies we'll need for long-term lunar exploration and human missions to Mars.

Bat-inspired aerial robot for search and rescue
A video from Worcester Polytechnic Institute WPI on youtube
-----------
A research team led by Nitin Sanket, faculty in the Department of Robotics Engineering at Worcester Polytechnic Institute, demonstrates a version of their bat-inspired aerial robot. The team is developing a robot for search and rescue applications in dark, dusty, and dangerous environments with poor visibility. The lightweight robot relies on echolocation, just like bats, a physical acoustic shield to reduce propellor noise, and an AI-based neural network called Saranga that recovers weak echo signals from very noisy measurements by learning patterns over time.

A hidden brain switch could change everything we know about hunger and fullness! 🧠

Scientists from the University of Maryland and University of Concepción discovered that astrocytes, brain cells once thought to just support neurons, actively signal when you’re full. After eating, tanycytes detect glucose and release lactate, which activates astrocytes. These astrocytes then communicate with neurons to suppress appetite, creating a full-body feeling of satiety.

This breakthrough could lead to innovative treatments for obesity and eating disorders by targeting astrocytes or the HCAR1 receptor. While still in animal models, the research offers a glimpse into a future where brain chemistry could help regulate healthy eating patterns.

Scientists Discover Hidden Brain “Stop Eating” Switch: How Astrocytes Control Appetite

Scientists uncover a hidden brain switch controlling appetite. Astrocytes, previously thought to only support neurons, signal fullness, offering potential new treatments for obesity and eating disorders.

A stunning breakthrough in quantum physics has just been announced!
Atoms in two places at once—quantum physics just got real.

For the first time ever, scientists have observed pairs of atoms existing in two places simultaneously—a phenomenon once thought to belong only in theory.

Using helium atoms instead of light particles, researchers were able to demonstrate quantum entanglement in motion, opening the door to deeper exploration of how the universe works at its most fundamental level.

This discovery could help answer one of the biggest questions in science: how quantum mechanics connects with gravity and the large-scale structure of the universe.

The future of physics just got even more exciting—and a little more mind-bending.

Quantum Breakthrough: Scientists Observe Pairs of Atoms Existing in Two Places at Once for the First Time

Scientists have observed pairs of atoms existing in two places at once for the first time, marking a major breakthrough in quantum physics and the study of reality.

Meet Jonathan the tortoise, the world’s oldest living land animal! 🐢 Born around 1832, Jonathan has lived nearly two centuries on the remote island of Saint Helena, outliving generations of humans and fellow tortoises.
Jonathan the tortoise: 193+ years of life, history, and enduring charm. 🐢🌿

From his early days arriving as a fully grown adult from the Seychelles to becoming a local and global icon, Jonathan has captured hearts worldwide. Despite a viral hoax in 2026 falsely claiming his death, Jonathan remains alive, roaming the grounds of Plantation House under the care of veterinarian Joe Hollins.

At 400 pounds and with a curious personality, Jonathan enjoys sunbathing, observing tennis matches, and interacting with visitors. He has appeared on postage stamps, coins, and even in heartwarming stories of matchmaking. His resilience, longevity, and charm make him a symbol of hope and nature’s wonders.

Celebrate Jonathan’s incredible life and share the story of this living legend!
