Highly efficient carbon dioxide photoreduction guided by machine learning and first-principles calculation
Photocatalytic reduction of CO2 to high-value carbon-based fuels holds tremendous potential in addressing the growing energy crisis. However, the high C=O bond energy of CO2 molecules (750 kJ·mol-1) makes it challenging to activate and reduce CO2......»»
Could Ocean Engineering Pull Carbon from the Atmosphere as a Last Resort against Climate Change?
Changing the ocean’s chemical and biological makeup could force it to pull vast amounts of planet-warming carbon from the atmosphere. But is that a line we want to cross?.....»»
Improving hurricane modeling with physics-informed machine learning
Hurricanes, or tropical cyclones, can be devastating natural disasters, leveling entire cities and claiming hundreds or thousands of lives. A key aspect of their destructive potential is their unpredictability. Hurricanes are complex weather phenomen.....»»
Research reveals even single-cell organisms exhibit habituation, a simple form of learning

Astronomers discover a unique quasi-stellar object–dusty star-forming galaxy system
Astronomers from the Steward Observatory in Arizona and elsewhere report the discovery of a structure consisting of a quasi-stellar object (QSO) and a dusty star-forming galaxy (DSFG), linked by a bridge of ionized carbon. The finding of this unique.....»»
Invisible touch: Researchers give AI the ability to feel and measure surfaces
AI-based technologies are rapidly learning to see, converse, calculate and create. One thing they still don't do well, however, is measure or "feel" surfaces—a purely mechanical function......»»
New on-chip device uses exotic light rays in 2D material to detect molecules
Researchers have developed a highly sensitive detector for identifying molecules via their infrared vibrational "fingerprint." This innovative detector converts incident infrared light into ultra-confined "nanolight" in the form of phonon polaritons.....»»
Bug stops M4 Macs from virtualizing older macOS versions
Owners of Apple's newest Mac models running M4 chips aren't able to run older versions of macOS in a virtual machine, thanks to a mystery booting issue.MacBooks running older versions of macOSRunning a virtual machine with older generations of macOS.....»»
Scientists Establish the Best Algorithm for Traversing a Map
Dijkstra’s algorithm was long thought to be the most efficient way to find a graph’s best routes. Researchers have now proven that it’s “universally optimal.”.....»»
Extreme heat weakens land"s power to absorb carbon, analysis finds
A new European Space Agency-backed study shows that the extreme heat waves of 2023, which fueled huge wildfires and severe droughts, also undermined the land's capacity to soak up atmospheric carbon. This diminished carbon uptake drove atmospheric ca.....»»
PS5 vs. Xbox Series S
The next generation of video game consoles is here, and Microsoft has come out swinging with its Xbox Series S. How does this machine stack up against the PS5?.....»»
Ytterbium thin-disk lasers pave the way for sensitive detection of atmospheric pollutants
Alongside carbon dioxide, methane is a key driver of global warming. To detect and monitor the climate pollutants in the atmosphere precisely, scientists at the Max Planck Institute for the Science of Light (MPL) have developed an advanced laser tech.....»»
Can AI improve plant-based meats? Using mechanical testing and machine learning to mimic the sensory experience
Cutting back on animal protein in our diets can save on resources and greenhouse gas emissions. But convincing meat-loving consumers to switch up their menu is a challenge. Looking at this problem from a mechanical engineering angle, Stanford enginee.....»»
