AI Reveals New Possibilities in Matrix Multiplication
Mathematicians love a good puzzle. Even something as abstract as multiplying matrices (two-dimensional tables of numbers) can feel like a game when you try to find the most efficient way to do it. It's a little like trying to solve a Rubik's Cube in as few moves as possible — challenging, but alluring. Except that for a Rubik's Cube, the number of possible moves at each step is 18… Source

Remdesivir reduces COVID-19 mortality in a real-world setting
Researchers have found that administering remdesivir with corticosteroids to Asian patients who are critically ill with COVID-19 within 9 days of symptom onset reduces overall mortality. Starting treatment later did not have the same effect, suggesting that higher viral loads and serious lung damage impair the effectiveness of this treatment.

Climate plays large role in carbon release from streams, researchers find
There is a less obvious source of carbon emissions than cars and factories: rivers and streams.

But what factors impact DIC concentrations? A team of Penn State engineers has now determined that both water discharge—or the volume

New insight into how long-banned chemicals (PCBs) unleash their toxicity inside the body
In the past, PCBs were utilized in a vast range of industrial and commercial products. These highly carcinogenic chemical compounds remain in our environment and accumulate inside organisms. Chiral PCBs are particularly dangerous because they have more chlorine atoms, which are hard for the body to break down, so they can accumulate in the body easily. Also, their isomers are metabolized different
