Imagine drawing on something as delicate as a living cell — without damaging it. Researchers at the University of Missouri have made this groundbreaking discovery using an unexpected combination of tools: frozen ethanol, electron beams and purple-tinted microbes.

By advancing a method called ice lithography, the team was able to etch incredibly small, detailed patterns directly onto fragile biological surfaces.

Graduate students at The University of Texas at Austin have filled a large gap in knowledge about Mars' water cycle. Their research on water percolating from surface to aquifer could change the picture of what early Mars was like, suggesting that less of the planet's water may have been available to become rain and refill lakes and oceans.

Researchers analyzed a global database of 500,000 strange streaks that occur on steep Martian slopes, concluding that they’re most likely caused by dry processes rather than liquid flow.

The largest sample of galaxy groups ever detected has been presented by a team of international astronomers using data from the James Webb Space telescope (JWST) in an area of the sky called COSMOS Web. The study marks a major milestone in extragalactic astronomy, providing unprecedented insights into the formation and evolution of galaxies and the large-scale structure of the universe.

UC Berkeley astronomers searching for massive black holes shredding stars found one in an unusual place — 2,600 light years from the core of a galaxy. The roque black hole may be from an earlier merger with another galaxy, or have been tossed out of the core after interacting with two other black holes. This is the first ever optically discovered off-nuclear tidal disruption event. Eventually, the two could merge and produce ripples of gravitational waves.

A joint research team from the Defense Innovation Institute at the Chinese Academy of Military Science and the College of Aerospace Science and Engineering at the National University of Defense Technology has developed a novel method for satellite 3D component layout optimization based on engineering requirements. The satellite 3D component layout problem involves determining both component assignment schemes and position variables simultaneously with complex multidisciplinary constraints, making it an NP-hard multi-constrained bilevel combinatorial optimization problem. The team proposed a Mixed Integer Programming (MIP) model to formulate the heat dissipation performance objective and the constraints of component 3D geometry, system stability, and special component position, transforming the original bilevel problem into a single-level optimization problem. Case studies demonstrate that the proposed method can efficiently generate layout solutions, providing fresh insights for engineering layout design.
