About Sedeer el-Showk, Ph.D.

Sedeer became a professional science writer after finishing a degree in biology. He also writes poetry and sff, and somehow juggles an ever-growing list of hobbies from programming to knitting to gardening. Eternal curiosity and good fortune have taken him to many parts of the world, but he’s settled in Helsinki, Finland for the moment. He hopes he’ll never stop learning new things.

According to new research, mutations accumulate in the mitochondrial DNA of egg cells, leading to changes in cellular metabolism, which result in reduced fertility. The study also showed that NMN treatment can restore the metabolic balance in aging mouse oocytes, rescuing fertility. Defective eggs Although malfunctioning of mitochondria and the accumulation of mutations in mitochondrial...

A short-term caloric restriction diet enhanced a DNA repair process known as non-homologous end joining. These results may partially explain how caloric restriction and similar diets increase lifespan and healthspan in a wide range of organisms. Eat less, live longer Caloric restriction – that is, reduced caloric intake without malnutrition – is one of the...

A gene therapy treatment can ameliorate the loss of motor function and muscle strength in old mice, offering elderly people hope for continuing their active lives. DOK7 is crucial for muscle function Declining motor function is common with aging and can significantly reduce the quality of life. This decline occurs at least in part due...

A novel treatment that inhibits the activity of the Cdc42 protein has been found to extend the lifespan of aged mice, most likely through epigenetic changes and regulation of inflammatory cytokines. Cdc42 is linked with lifespan Cdc42 is a RhoGTPase, a kind of signaling protein involved in a variety of processes in eukaryotic cells. It...

The well-known resistance of naked mole rats to aging and aging-related effects is due at least in part to an unusual ability to clear away senescent cells. This suggests that senolytic drugs, which aim to do the same in humans, may prove a fruitful path to longevity. Naked mole rats live much longer than other...

The mechanisms at work in the blood-brain barrier change with age, affecting the selectivity of this vital interface. The blood-brain barrier The blood-brain barrier is a layer of cells in the blood vessels of the brain that prevents molecules in the blood from crossing into the central nervous system. Selective transport across the barrier is...
