Nobel Prize Honors Inventors of ‘Quantum Dot’ Nanoparticles
The Nobel Prize in Chemistry has been awarded to three researchers who harnessed the quantum behaviors of semiconductor nanocrystals.
How the Brain Protects Itself From Blood-Borne Threats
To buffer the brain against menaces in the blood, a dynamic, multi-tiered system of protection is built into the brain’s blood vessels.
How a Human Smell Receptor Works Is Finally Revealed
After decades of frustration, researchers have determined how an airborne scent molecule links to a human smell receptor.
Inside Ancient Asteroids, Gamma Rays Made Building Blocks of Life
A new radiation-based mechanism adds to the ways that amino acids could have been made in space and brought to the young Earth.
Machine Learning Highlights a Hidden Order in Scents
Efforts to build a better digital “nose” suggest that our perception of scents reflects both the structure of aromatic molecules and the metabolic processes that make them.
Molecule-Building Innovators Win Nobel Prize in Chemistry
The chemists Carolyn Bertozzi, Morten Meldal and K. Barry Sharpless were recognized for their development of click chemistry and bioorthogonal chemistry.
Quantum Complexity Tamed by Machine Learning
If only scientists understood exactly how electrons act in molecules, they’d be able to predict the behavior of everything from experimental drugs to high-temperature superconductors. Following decades of physics-based insights, artificial intelligence systems are taking the next leap.
