Microscope images could be obtained much more quickly—rather than one pixel at a time—thanks to a new imaging method for neutral atomic beam microscopes developed by Swansea University researchers. It could ultimately lead to engineers and scientists getting faster results when they are scanning samples.
Following NASA ’s DART mission, which successfully tested asteroid deflection techniques by colliding with the moonlet Dimorphos, extensive research has revealed insights into the geological features and evolutionary history of the Didymos asteroid system.
Studies have characterized the surface and interior of these celestial bodies, examined their formation processes, and assessed their response to impacts. These findings not only provide a clearer understanding of binary asteroid systems but also enhance planetary defense strategies.
In the months that followed NASA’s Double Asteroid Redirection Test (DART) mission, which sent a spacecraft to intentionally collide with an asteroid moonlet, the science team verified that kinetic impact was a viable deflection technique, proving one effective method of preventing future asteroid strikes on Earth.
A magnet-and-coil system reveals how acoustic waves reflect and refract when the host medium suddenly changes elasticity.

The first-ever detonation engine could be the future (and the end of combustion): It has predicted by Hawking, and finally created by engineers.
A new study now published in Science reveals that the memory for a specific experience is stored in multiple parallel “copies.” These are preserved for varying durations, modified to certain degrees, and sometimes deleted over time, report researchers at the University of Basel.
The ability to turn experiences into memories allows us to learn from the past and use what we learned as a model to respond appropriately to new situations. For this reason, as the world around us changes, this memory model cannot simply be a fixed archive of the good old days.
Rather, it must be dynamic, changing over time and adapting to new circumstances to better help us predict the future and select the best course of action. How the brain could regulate a memory’s dynamics was a mystery—until multiple memory copies were discovered.
Scientists have successfully recovered the first long section of rocks originating from the Earth’s mantle, the layer beneath the crust and the planet’s largest component. These rocks are expected to shed light on the mantle’s role in the origins of life on Earth, the volcanic activity that occurs when it melts, and its influence on the global cycles of crucial elements like carbon and hydrogen, according to the research team.
The nearly continuous 1,268 meters (4160 feet) of mantle rock was recovered from a “tectonic window,” a section of the seabed where rocks from the mantle were exposed along the Mid-Atlantic Ridge, during Expedition 399 “Building Blocks of Life, Atlantis Massif” of the ocean drilling vessel JOIDES Resolution in Spring 2023.
With attempts dating back to the early 1960s, the recovery was a record-breaking achievement led by the International Ocean Discovery Program, an international marine research consortium of more than 20 countries that retrieves cores—cylindrical samples of sediment and rock—from the ocean floor to study Earth’s history.
Bowhead whales, the silent giants of the Arctic, play a crucial role in the ocean’s ecosystem. These amazing creatures can grow up to 60 feet long and have fascinated scientists for years with their unique behaviors and impressive lifespans.
A recent study has shed light on their lives, uncovering patterns that boost our understanding of marine life and shake up some of our old ideas.
Bowhead whales are truly amazing creatures. Known for their massive size and sturdy build, they have the largest mouth of any animal, which they use to filter-feed on tiny organisms like zooplankton.
