Two NASA rocket missions are taking to the Alaskan skies in hopes of discovering why some auroras flicker, others pulsate, and still others are riddled with holes. Understanding these peculiar features is part of NASA’s goal to understand the space environment around our planet, which can affect both spacecraft and astronauts. Two NASA rocket missions are…
The ISS’s orbit is slowly decaying. While it might seem a permanent fixture in the sky, the orbiting space laboratory is only about 400 km above the planet. There might not be a lot of atmosphere at that altitude. However, there is still some, and interacting with that is gradually slowing the orbital speed of…
Although fertilizers are essential for global food production, they also contribute to greenhouse gas emissions. The war in Ukraine has caused supply chain disruptions and price increases. How can fertilizer production become more sustainable and resilient to geopolitical crises? Although fertilizers are essential for global food production, they also contribute to greenhouse gas emissions. The war…
A research team led by Dr. Tetsuya Muramoto from the Faculty of Science at Toho University has demonstrated the mechanisms by which periodic chemical signal frequencies in cells regulate gene expression via transcription factors and influence the cell fate determination processes. This discovery was made using optogenetic technology, which facilitates the manipulation of biological phenomena…
A massive flood called the Zanclean megaflood ended the Messinian salinity crisis, which lasted between 5.97 and 5.33 million years ago, according to new research led by Monterey Bay Aquarium Research Institute (MBARI).

The source of the newly-detected fast radio burst, FRB 20240209A, is in the distant outskirts of an ancient elliptical galaxy, which is located 2 billion light-years from Earth and has a mass of more than 100 billion solar masses. The post Repeating Fast Radio Burst Traced to Outskirts of Quiescent Elliptical Galaxy appeared first on…
Five elephants at a Colorado zoo may be “majestic” but do not have the legal right to pursue their release since they aren’t human. That was the ruling Tuesday from Colorado’s highest court. It follows a similar court defeat in New York in 2022 for an elephant named Happy at the Bronx Zoo in a…
Scotland must do more to help hydropower facilities maximize their output and prevent negative impacts on wildlife in the face of the challenges posed by climate change, according to a new report.

Trees need a certain number of warm days in their growing seasons to grow properly; otherwise, the cell walls of new growth don’t lignify properly, creating blue rings that appear when wood samples are dyed.
