The bacteria Burkholderia and Pseudomonas are more common in soils with higher levels of total mercury and methylmercury.
Microbes in mercury-contaminated soil have more genes related to stress response, moving substances across cell membranes, and phosphate metabolism compared to less contaminated soils.
The amount of mercury that can actually be taken up by organisms doesn't always match the total mercury in the soil, showing that the chemical form of mercury matters more than just how much is present.
In soils with mercury contamination, the most common types of fungi belong to groups called Ascomycota and Basidiomycota.
In soils with mercury contamination, the most common types of bacteria belong to groups called Pseudomonadota, Bacteroidota, Bacillota, Acidobacteriota, and Actinomycetota.
In soils with more mercury, there are fewer types of bacteria, but the variety of fungi stays about the same and is greatest in soils with the least mercury.
Eating more protein after working out makes your whole body build more protein - the more protein you eat, the more protein your whole body builds.
Eating protein after working out doesn't change most amino acid levels in your muscles - only the branched-chain amino acids like leucine increase with bigger protein meals.
Eating a big protein meal (100g) after working out keeps your blood amino acid levels high for the whole 12 hours, while a smaller meal (25g) only keeps them high for the first 5 hours.
Eating protein after working out only increases the building of connective tissue in muscles for about 4 hours - after that, the building rate goes back to normal.
Eating more protein after working out leads to a better overall protein balance in your body - the more protein you eat, the more positive your protein balance becomes.
Eating protein after working out doesn't change most amino acid levels in your muscles, but it does increase the levels of branched-chain amino acids like leucine, especially with bigger protein meals.
When you eat a big protein meal (100g) after working out, a larger portion of the protein building blocks for your muscles comes directly from that meal (27%) compared to a smaller meal (9%).
Eating protein after working out only affects the muscle's signaling pathways for about 4 hours - after that, the signaling goes back to normal even though muscle building continues.
Eating protein after working out doesn't change the muscle's cleanup process for damaged proteins - the body still cleans up damaged proteins normally even after eating protein.
Eating a big protein meal (100g) after working out makes your body make more plasma proteins than a smaller meal (25g) - about 14-20% more over 4-12 hours.
Eating protein after working out doesn't change how fast your muscles break down protein - it just helps build more muscle without affecting the breakdown process.
When you eat a big protein meal (100g) after working out, your muscles absorb more of that protein for building than when you eat a smaller meal (25g) - about 13% of the big meal gets used for muscle building.
Eating protein after working out doesn't make your body burn more protein as fuel than it needs for building muscle - most of the protein goes toward building muscle instead of being burned for energy.
When you eat a big protein meal (100g) after working out, your body releases more protein building blocks into your blood than when you eat a smaller meal (25g) - about 53g vs 16g over 12 hours.
Eating a big protein meal (100g) after working out makes your muscles keep building for longer than a smaller meal (25g), at least for 12 hours.
Glycine helps people sleep better in a different way than sleeping pills, because it helps them fall asleep faster and reach deep sleep faster without changing how much time they spend in different sleep stages.
Taking 3 grams of glycine before bed doesn't make people feel sleepy during the day.
Taking 3 grams of glycine before bed doesn't change how quickly people respond in memory tasks.
