Meta’s AI boss, Yann LeCun, said that the company has invested $30 billion in NVIDIA AI GPUs for AI training, new Llama 3 models coming soon.
Chemistry, with its intricate processes and vast potential for innovation, has always been a challenge for automation. Traditional computational tools, despite their advanced capabilities, often remain underutilized due to their complexity and the specialized knowledge required to operate them.
Now, researchers with the group of Philippe Schwaller at EPFL have developed ChemCrow, an AI that integrates 18 expertly designed tools, enabling it to navigate and perform tasks within chemical research with unprecedented efficiency. Their research is published in Nature Machine Intelligence.
“You might wonder why a crow?” asks Schwaller. “Because crows are known to use tools well.”
The Silicon Hospital is OpenWater’s revolutionary open-source software and hardware platform.
A research team led by Dr. Serge Krasnokutski from the Astrophysics Laboratory at the Max Planck Institute for Astronomy at the University of Jena had already demonstrated that simple peptides can form on cosmic dust particles. However, it was previously assumed that this would not be possible if molecular ice, which covers the dust particle, contains water—which is usually the case.
Now the team, in collaboration with the University of Poitiers, France, has discovered that the presence of water molecules is not a major obstacle for the formation of peptides on such dust particles. The researchers report on their finding in the journal Science Advances.
Chemistry in the icy vacuum “We have replicated conditions similar to those in outer space in a vacuum chamber, also adding substances that occur in so-called molecular clouds,” explains Krasnokutski. These substances include ammonia, atomic carbon, and carbon monoxide. “Thus, all the chemical elements needed for simple peptides are present,” adds the physicist.
The natural vein structure found within leaves—which has inspired the structural design of porous materials that can maximize mass transfer—could unlock improvements in energy storage, catalysis, and sensing thanks to a new twist on a century-old biophysical law.
Nanoscale materials present us with astonishing chemical and physical properties that help materialize applications such as single molecular sensing and minimally invasive photothermal therapy—which were once just theories—into reality.
Nanostructured high entropy alloys—metals made from a chaotic mix of several different elements—show a lot of promise for use in industries such as aerospace and automotive because of their strength and stability at high temperatures compared with regular metals.
