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.

Elderly Person Coughing
Researchers have used a big data approach to disentangle cellular and physiological changes that are specific to COVID-19 from those caused by aging [1]. Identifying these improves our understanding of the disease and may help explain why COVID-19 has a more severe effect on older people. A tangled skein The enormous impact of COVID-19 around...
Invisibility
Gene editing can make stem cells invisible to the immune system, making it possible to carry out cell therapy transplants without suppressing the patients' immune response [1]. Help me help you Cellular therapies involve transplanting cells into a patient to replace the activity of malfunctioning or damaged cells. For example, cardiomycetes could be transplanted to...
Sheep
Researchers have shown that castration makes male sheep live longer, and they’ve also used genomic data to get a basic understanding of the mechanism behind this longevity [1]. While castration is unlikely to be part of a life extension therapy, unraveling its effect on lifespan will help flesh out the link between sex hormones and...
Gut bacteria
Most of the genetic changes associated with increasing age disappear in the absence of gut bacteria, according to a new fruit fly study [1]. It’s a pretty surprising finding, and while there are some important implications, it’s also a bit challenging to interpret. A flat aging line The experiment itself was relatively straightforward. A team...
Pulling backwards
A new study [1] about the 'invariant rate of ageing' has led to reports that aging is unstoppable and that we cannot cheat death. However, this reporting is based on a misunderstanding of what the study actually says. The misinterpretations The study shows that "immortality and everlasting youth are the stuff of myths," according to...
Elderly muscle
Muscular degradation with age isn’t the result of a decline in the intrinsic regenerative ability of muscles, according to new research [1].  Instead, sarcopenia is likely due to changes in the muscle microenvironment that reduce repair and regeneration. Declining muscles Age-related muscle loss can begin as early as a person’s fourth decade, and sarcopenia can...
