As Neuroskeptic blog ends, reflections on skeptical science blogging

skeptic magazine science blogging

It seems like being somewhat skeptical would be an inherent part of being a biomedical scientist. But not always it seems. On the other hand, some of us take it to another level by science blogging out our skepticism about certain topics. Note that there’s something called the Skeptics Society that publishes a magazine Skeptic. …

Weekly reads: stem cell videos, cystic fibrosis, papers

stem cell videos

As part of our weekly reads I’m including one of my latest videos in our Stem Cell Channel on YouTube below. This particular video fact-checks stem cell face creams, but I’ve got quite a few more including on stem cell supplements, different kinds of stem cells and more. You might guess my view of such …

Weekly reads: embryo pubs stir things up, organoids crying, & more

organoids tear glands sm

This was an unusual week in that three papers in a sense collided together related to embryo production and growth, raising new research possibilities but also serious ethical questions. New research: what is an embryo & what is not? The first two Nature papers reported generating the most realistic models of human embryos from scratch …

New lab-grown blastoids are strikingly similar to human embryos

blastoids nature paper figure 2

A new word has been added to the lexicon of human stem cell research – blastoids, aka “blastocyst-like structures.” Unlike the familiar three-layered embryo that emerges during the third week of prenatal development, the earlier blastocyst resembles a fluid-filled soccer ball, with a smear of cells on the interior face destined to develop into the …

Can Gene-Edited Stem Cells Treat Cystic Fibrosis?

human-IPS-cells-made-in-Knoeplfer-lab-stained-for-TRA-160

Drugs that restore the shape of the errant protein behind cystic fibrosis (CF) have, over the past eight years, helped the majority of patients, who have certain mutations. Gene-corrected stem cells might offer a “mutation agnostic” option to CF. CF results from a glitch in a glycoprotein with the unwieldy name “cystic fibrosis transmembrane conductance …

Mesoblast MSCs Quell Peds GvHD; On Road to FDA Approval?

MSCs-mesenchymal-stem-cells-stromal-cells-small

Graft-versus-host disease (GVHD) is counterintuitive In the weeks and months following a transplant, a major concern is the recipient’s immune system rejecting the “foreign” biological material. But in GVHD, the opposite happens: transplanted tissue unleashes a horde of T cells that spark a cascade of inflammation, within 100 days. Typically, GVHD follows a bone marrow …

Sniffing Out Stem Cells Behind COVID-Skewed Olfaction

woman-smelling-food-COVID-19-Anosmia

In COVID-19, the sense of smell can diminish, vanish, or oddly skew, for weeks or months. The loss usually starts suddenly and is more than the temporarily dulled chemical senses of a stuffy nose from the common cold. As researchers followed up mounting reports of loss of olfaction, a surprising source of perhaps the longest-lasting …
