Diatoms contribute to global oxygen production, marine food webs, and carbon sequestration, but scientists predict that diatom populations will decline due to ocean acidification associated with climate change.

Scientists show how microbes living in a salty spring near the North Pole might resemble those that could have survived on the Red Planet—or in ocean worlds.
Note for me: Mitochondria, the organelles supply energy to cells. If the mitochondria are faulty, it may foster body fibrosis. As we get older, fibrosis can stiffen the heart, lungs, liver, and ovaries. As mice and humans get older, these structures begin to malfunction, producing less of the energy-rich molecules that cells need and generating more destructive metabolic byproducts. BGP-15 is a drug, which tunes up the organelles. Two other molecules that bolster mitochondria are, 1. Metformin, an anti-diabetes drug sometimes prescribed for infertility. 2. MitoQ, which is often touted as an antiaging supplement. How fibrosis undermines fertility remains uncertain, but it may make ovarian tissue rigid. An egg matures inside a cradle known as a follicle, which balloons to about 1 million times its original size before bursting to release the egg. The buildup of connective tissue might imprison follicles, preventing them from enlarging and thus thwarting egg development. The BGP-15 spurs mice to produce an enzyme that dissolves the collagen fibers in connective tissue, which may liberate the follicles. The BGP-15 was spurred on 12-month-old mice, which is comparable to a 35-year-old human.
Closely studying these magnetic foraminifera could lead to new insights about the evolution of magnetic life.
:A lysosome is a membrane-bound cell organelle (sphere-shaped sacs) that contains digestive enzymes.They recycle unwanted proteins.If unwanted proteins build up in our body they can kill our neurons and lead to Parkinson’s.

Note for me:There are roughly 38 trillion microbes in our body than human cells (about 30 trillion).Every time we eat, we’re feeding a host of microbes, the gut’s microbiome.And what gut microbes eat makes a huge difference in our health. A healthy microbiome can protect against metabolic disorders and inflammatory bowel disease.Microbes transportation (musculoskeletal system), communication (the nervous system), infrastructure and goods (the endocrine system), diplomacy and defence (the immune system):Microbes create essential vitamins and proteins.They break down toxins.And they play an important role in the immune system.Well-fed gut microbes do not allow dangerous bacteria to grow, such as bad strains of E. coli. Mental health disorders are due to the wrong balance of gut bacteria, such as depression and dementia.Some cancers, and perhaps even autoimmune diseases such as lupus, multiple sclerosis, and type 1 diabetes, could relate to an out-of-whack microbiome.The feed of our food should include fibre, phenols, fermented foods, and (healthy) fats.Whole grains and beans have fibre.Phenols give fruits and vegetables their colours.Fermented foodsWhen it comes to fats, focus on omega-3s.Oils that come from fruits instead of grains, such as coconut oil.Nuts contain omega-3 fats.Butter, especially when it’s made from milk from grass-fed cows. Fibre, phenols, fermented foods, and healthy fats are the perfect food for gut microbiomes that keep our bodies running smoothly.If you want to stay healthy, pay attention to what you feed your microbes.

An infographic showing the daily cycles of A photosynthesis, B mucosphere production, C prokaryotic and eukaryotic prey attraction and capture, D peduncular phago-heterotrophic feeding, E mucosphere abandonment and carbon export potential, and F asexual or sexual reproduction.
The solid yellow arrows represent the daily cycle of the P. cf. balticum cell including entering the mucosphere during construction in (B) and exiting the mucosphere in (E).
The light blue arrows show the P. cf. balticum cell through the asexual reproduction stage and the pink arrows represent the sexual reproduction stage.
The broken yellow arrows signify one of the succeeding P. cf. balticum cells from either of the reproduction stages re-entering the daily cycle.
One anthropologist has made it her mission to remove racial prejudices from the study of hair and find the evolutionary roots of hair diversity.
In South Africa, authorities developed a pencil test to determine someone’s race. They placed a pencil in a person’s hair, and if it stayed in place due to their tight curls, they were classified as “Native” (Black) or “Colored” on their identity documents and segregated accordingly.
