Microorganisms remove much of this human-derived nitrogen in coastal sands through a process called denitrification. Denitrification generally only occurs in the absence of oxygen. However, observations indicate that it also happens in oxygenated sands, via a thus far unknown mechanism. /news/2025-06-nitrogen-loss-sandy-shores-big.html Ecology Cell & Microbiology Mon, 02 Jun 2025 11:06:02 EDT news668081161 Water reshapes Earth through slow, powerful erosion, carving intricate landscapes like caves and pinnacles in soluble rocks such as limestone.

The team, led by scientists at the Broad Institute and the Tufts University School of Medicine, used a microfluidic approach to screen more than 1 million combinations of antibiotics, small molecules, and bacteria. They identified a small molecule that boosts the power of the antibiotic rifampin in certain bacteria by weakening their defenses. The team also developed another molecule that was even more potent. /news/2025-05-combinatorial-screening-uncovers-molecules-antibiotics.html Cell & Microbiology Molecular & Computational biology Wed, 28 May 2025 12:51:04 EDT news667655461 Organic particles that settle on the seabed ensure CO2 stays locked.
