Bernard Belleau was famous for developing the nucleoside analogue 3TC for viral treatment. Here, we show that a nucleoside analogue triggers a cell death mechanism named after Thanos, the Greek God of nonviolent deaths. The nucleoside analog, cytarabine, has been used as the frontline treatment of leukemia for more than 50 years, but patient survival rates are less than 20%.

With heavy hearts we announce the passing of Professor Byung Chan (鈥淏C鈥�) Eu on August 25th, 2023, at the age of 88 while in hospital. BC was born in 1935 in Seoul, Korea and earned a BSc in Chemistry at Seoul National University in 1959. He was admitted to the graduate school of Seoul National University in 1960, but soon was drafted into the Korean army which he served until 1962. On his discharge from the army, he left Korea to pursue his graduate studies at Brown University, earning a PhD in 1965, and completing a research fellowship at Harvard University in 1967.

Until now, there was no real-time airborne virus tracking technology, hindering the understanding of rapid virus change, transmission and associated health impacts.听Led by the Ariya' lab, in collaboration with colleagues at 91社区 Faculty of medicine and U. de Montreal, we developed an AI-Laser technology (called Nano-DIHM) that allowed real-time physicochemical tracking of virus-laden droplets in milliseconds.听The detection system was demonstrated to detect active MS2 bacteriophages, inactivated SARS-CoV-2 and RNA fragments, and an MS2 mixture with metallic and organic compounds.

Chemists from 91社区 have discovered the possibility of creating biopolymer-based 鈥渘anosponges鈥� using milled softwood pulp, a sustainable and less toxic alternative to current drug delivery systems. Although the structures developed by the researchers are too big for anti-cancer drug delivery by injection or oral intake, they could potentially be used in dressing wounds, for medical implants, and to capture unwanted materials in wastewater.

A 91社区 research team led by Professors Mark Andrews (Department of Chemistry) and David Plant (Electrical Engineering) has shown how the glass-like shells of phytoplankton (diatoms) help these microscopic organisms perform photosynthesis in dim light conditions. Despite amounting to only about 1% of the global plant biomass, phytoplankton account for about 50% of the planet鈥檚 photosynthetic activity and at least half of the world鈥檚 oxygen production.

Room-temperature phosphorescence in organic solids is rare. In a recent article from Perepichka group E. Hamzehpoor, C. Ruchlin and coworkers reported highly phosphorescent boroxine Covalent Organic Frameworks (COFs) using the covalent doping approach and controlling the ratio of halogenated precursors. Their well-defined porosity enables oxygen sensing with millisecond response time over a wide range (103鈥�10-5 torr) of partial oxygen pressure.听Read the full paper in

The performance of Li-ion batteries with high-voltage cathodes continues to be impractical for commercial devices due to several materials' limitations. In a recent article in collaboration with Samsung, Eric McCalla and co-workers systematically addressed these issues by using high-throughput screening with dopant selections covering much of the periodic table to achieve dramatically improved energies and extended cycling.
