Mimicking how plants convert sunlight into energy has long been a dream for scientists aiming to create renewable energy solutions. Artificial photosynthesis is a process that seeks to replicate nature’s method, using sunlight to drive chemical reactions that generate clean energy. However, creating synthetic systems that work as organically as natural photosynthesis has been a significant challenge until now.
Tesla began rolling out a significant update to its Full Self-Driving (FSD) software on Saturday, shifting the city-streets driving system to a single, end-to-end neural network model in FSD version 12.5.6.3.
Last week, Tesla CEO Elon Musk said the company’s FSD technology “is now almost entirely AI.” In early October, Musk had stated that FSD “will soon exceed 10,000 miles between critical interventions, which is a year of driving for most people.”
SpaceX will launch Apple partner Globalstar’s new MSS satellites as part of the iPhone’s satellite connectivity features.
After thousands of years as a highly valuable commodity, silk continues to surprise. Now it may help usher in a whole new direction for microelectronics and computing.
While silk protein has been deployed in designer electronics, its use is currently limited in part because silk fibers are a messy tangle of spaghetti-like strands.
Now, a research team led by scientists at the Department of Energy’s Pacific Northwest National Laboratory has tamed the tangle. They report in the journal Science Advances (“Two-dimensional silk”) that they have achieved a uniform two-dimensional (2D) layer of silk protein fragments, or “fibroins,” on graphene, a carbon-based material useful for its excellent electrical conductivity.
A 9th grader from Snellville, Georgia, has won the 3M Young Scientist Challenge, after inventing a handheld device designed to detect pesticide residues on produce.
Sirish Subash set himself apart with his AI-based sensor to win the grand prize of $25,000 cash and the prestigious title of “America’s Top Young Scientist.”
Like most inventors, Sirish was intrigued with curiosity and a simple question. His mother always insisted that he wash the fruit before eating it, and the boy wondered if the preventative action actually did any good.
Antonia, a cloned black-footed ferret at the Smithsonian’s National Zoo and Conservation Biology Institute, has produced two healthy offspring that will help build genetic diversity in their recovering population.
Quantum theory is distinguished by its apparent indeterminism, a feature that raises the question: Is this uncertainty inherent to Nature, or might…

The world is full of unusual unicellular organisms and microbes, many of which have not been discovered yet. In 2017, scientists identified a single-celled marine organism called Chromosphaera perkinsii in sediments collected from Hawaii. This species is estimated to be over a billion years old, making it older than the world’s most ancient animals. Researchers determined that this species has significant similarities to some animal embryos, though it is typically unicellular. The findings, which have been reported in Nature, suggested that some of the genetic mechanisms underlying complex life are present in C. perkinsii, or that it has evolved those characteristics independently.
The investigators noted that this study seems to answer the question of whether the chicken came before the egg; it was apparently the egg, since the genetic tools for making eggs existed prior to the emergence of chickens.
Today, only about 6% of the observable Universe is reachable due to cosmic expansion.
The Universe is a vast, wondrous, and strange place. From our perspective within it, we can see out for some 46 billion light-years in all directions. Everywhere we look, we see a Universe filled with stars and galaxies, but are they all unique? Is it possible, perhaps, that if you look far enough in one direction and see a galaxy, that you’d also see that same galaxy, from a different perspective, in the opposite direction? Could the Universe actually loop back on itself? And if you traveled far enough in a straight line, would you eventually return to your starting point, just as if you traveled in any one direction for long enough on the surface of the Earth? Or would something stop you?
Fermilab is tackling the extreme conditions generated in neutrino experiments to ensure the success of future research.
“Researchers need to overcome three challenges to make a lasting target: radiation damage, high temperatures and stress from thermal expansion,” remarked the press release.
Nanofibers, incredibly thin threads with exceptional strength and flexibility, are being investigated for their ability to better absorb the shock of the proton beam.
“A nanofiber developed by Fermilab engineer Sujit Bidhar is being researched as a potential target material due to its ability to mitigate thermal shock and be more resistant to radiation damage,” highlighted the press release.
