New Solid Material Turns Ordinary Sunlight Into High-Energy UV Light
6+ hour, 9+ min ago (29+ words) Two cups of warm water will never give you one cup of boiling water. Pour them together and you get a larger volume of lukewarm water, nothing more. The...
Chemists Can Now Rewrite a Drug Molecule in a Single Step Instead of Building It From Scratch
1+ week, 1+ day ago (573+ words) Using the new method for converting methylamines, complex compounds can be produced under simple conditions. Their target was a workhorse class of compounds called secondary N-methylamines, in which a nitrogen carries a single methyl group, a tiny CH" cap that…...
A Pinch of Scandium Keeps Carbon Nanotube Forests Growing Where Iron Alone Burns Out
1+ week, 6+ day ago (27+ words) Inside a quartz tube barely wider than a wrist, the temperature climbs past 800 degrees C and a forest begins to rise. Not trees, but carbon nanotubes,...
A One-Atom Shuffle Reveals Hidden Cancer-Drug Pocket That AI Couldn't Find
2+ week, 6+ day ago (54+ words) Two molecules sat side by side on the chemists' screen, near-identical twins. The same scaffold, the same atoms, the same everything, save for a single...
A Single Crystal Acts Like a Mirror One Way and Glass the Other, Bending Light Harder Than Any Known Natural Material
3+ week, 1+ day ago (288+ words) Take a sliver of molybdenum oxychloride, lay it on a chip of silicon, and turn it slowly under polarized light. At one angle it gleams back at you, bright...
Glowing Material Copies How Your Brain Folds Memory, Sight Together
3+ week, 2+ day ago (316+ words) Shine an ultraviolet pulse onto a particular crystal and it glows a soft blue. Switch off the lamp and the glow does not vanish. It lingers, fading...
Physicists Turn a Single Frozen Atom into a Camera That Sees Light Below the Diffraction Limit
3+ week, 4+ day ago (568+ words) Conceptual illustration of the Atom Camera. A single ultracold rubidium (Rb) atom trapped in an optical tweezer is spatially scanned to visualize the intensity and polarization distributions of a light pattern. That is the gist of a technique a Japanese…...
A Lab-Grown Diamond the Size of a Thumbnail Could Unify Radiation Measurement in Medicine
1+ mon, 2+ week ago (195+ words) New diamond-based detector for dosimetry. The team's heteroepitaxial diamond detector has vastly improved sensitivity per volume, promising compact and consistent dosimetry in a wide range of applications. The problem the detector is meant to solve is one of those quiet…...
Sticky Tape Stores Memories Like a Combination Lock, Without Electricity
1+ mon, 2+ week ago (28+ words) Pull a strip of ordinary Scotch tape partway off a surface and set it back down. Nothing remarkable seems to happen. The tape lies flat, a little crinkled...
Chemicals You Were Exposed to Before Birth May Be Scrambling Your Future Children's DNA
1+ mon, 2+ week ago (82+ words) That phrase, "enduring influence," is doing a lot of work here. The implication is that damage inflicted on the developing testis, in utero, does not resolve or reset. It compounds. Does this mean men whose mothers ate contaminated fish can't…...
