The first AI breast cancer sleuth that shows its work

Posted: 14 Jan 2022 07:30 AM PST

Researchers have developed an artificial intelligence platform to analyze potentially cancerous lesions in mammography scans to determine if a patient should receive an invasive biopsy. But unlike its many predecessors, the algorithm is interpretable, meaning it shows physicians exactly how it came to its conclusions.

Nanostructures get complex with electron equivalents

Complex crystals that mimic metals -- including a structure for which there is no natural equivalent -- can be achieved with a new approach to guiding nanoparticle self-assembly.

AI accurately diagnoses prostate cancer, study shows

Posted: 13 Jan 2022 08:15 AM PST

Researchers have completed a comprehensive international validation of artificial intelligence (AI) for diagnosing and grading prostate cancer. The study shows that AI systems can identify and grade prostate cancer in tissue samples from different countries equally well as pathologists. The results suggest AI systems are ready to be responsibly introduced as a complementary tool in prostate cancer care, researchers say.

A treasure map for the realm of electrocatalysts

Posted: 13 Jan 2022 08:14 AM PST

Efficient electrocatalysts, which are needed for the production of green hydrogen, for example, are hidden in materials composed of five or more elements. A team has developed an efficient method for identifying promising candidates in the myriad of possible materials. To this end, the researchers combined experiments and simulation.

For sustainable sulfur-tolerant catalysts, alloy the precious metals with phosphorus

Posted: 12 Jan 2022 11:51 AM PST

Researchers demonstrated that phosphorus-alloying significantly increases the activity of precious metal nanoparticles for the deoxygenation of sulfoxides into sulfides. In particular, ruthenium phosphide nanoparticles exhibit excellent catalytic activity and high durability against sulfur-poisoning, outperforming conventional catalysts.

'Hand in hand in hand': Three catalysts solve chemical problem
