One of the World’s Fastest Ocean Currents Remains Remarkably Stable

Climate models suggest that human activities might weaken the AMOC.

In a new study, scientists at the Cooperative Institute for Marine and Atmospheric Studies (CIMAS), the University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science, NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML), and the National Oceanography Centre reassess motion-induced voltages measured on a submarine cable and reevaluate the overall trend in the inferred FC transport. They found that the strength of the Florida Current, the beginning of the Gulf Stream system, and a vital component of the global Atlantic Meridional Overturning Circulation, or AMOC, has remained stable for the past four decades.

A breakthrough in ancient manuscript restoration

Scientists unveil an innovative technique to restore fragile texts, unlocking lost knowledge from the past.

Ancient manuscripts hold valuable historical insights, but over time, age and poor storage conditions can damage their readability and erase important details. A new study in PLoS ONE introduces a restoration method that removes degradation patterns from aged color manuscripts. This approach uses single-sided RGB images, eliminating the need for recto-verso alignment. By individually analyzing and detecting patterns, the technique enhances clarity and preserves historical information more effectively.

Penguin poop’s significantly impacts climate change

The findings establish a direct link between ecosystem activity and atmospheric processes.

Penguins play a surprising role in shaping Antarctica's atmosphere! A new study found that ammonia from penguin colonies, rather than the ocean, helps form new particles in the air when mixed with sulfuric acid from marine phytoplankton. Scientists used sensitive instruments to measure gases and particles on the Antarctic Peninsula, revealing how these processes contribute to cloud formation.

NASA’s LRO has made its most important discovery.

NASA’s Lunar Reconnaissance Orbiter (LRO) has been mapping the Moon since 2009, helping identify important scientific sites and potential landing areas for future missions. Recently, Scott Waring, a self-proclaimed UFO expert, claimed to have spotted a giant alien city on the Moon using Google’s Moon map. He shared his findings on his blog, saying he discovered a 9-mile-long (15 km) structure in the De Moraes Crater.

Mapping Our Cosmic Neighborhood: A 3D View of Near-Earth Objects

Watch all the known near-Earth asteroids and comets in real-time.

Astronomers discover many asteroids and comets each year, some of which are near-Earth objects (NEOs) that move through the inner solar system. NASA-funded researchers track these objects to identify potential threats to Earth. To help visualize them, NASA launched Eyes on Asteroids, a 3D real-time tool that shows NEOs moving through Earth’s orbital neighborhood.
