- Scientists create gut gel 'band-aid' made from the body's own bacteria - A problem for treating wounds to the gut or intestine is that patches and bandages won't stick to the slippery walls of the enclosure. To address this problem, a team of scientists from Harvard has created a hydrogel from the body's own bacteria that can be applied through syringes or sprays. The consistency of the gel is similar to the mucus that occurs naturally in the body, and it can be tailored for particular areas of the body. Postdoctoral fellow, and research team member, Anna Duraj-Thatte, describes the method as a hack of the natural healing process of the human body. To date, the process has only been tried on animals, so it may be a while before it shows up in operating rooms.
- STEEM The miscommunication between T cells and microbiome makes the poor mice fat - Journal club - In this post, @scienceblocks discusses
T cell–mediated regulation of the microbiota protects against obesity published by Petersen et al from June Round's and W. Zac Stephens' labs at Utah. It is published (in the) july 2019 edition of Science.
The post reports that, by editing the genome to effect the immune system's T cells and conducting experiments, researchers were able to determine that certain bacteria in mice effect weight gain. In fact, mice that are treated with antibiotics and then exposed to bacteria from the guts of obese humans become obese, whereas bacteria that are treated with antibiotics and exposed to bacteria from the guts of lean humans do not. Additionally, the post notes that scientists were able to spread the bacteria for obesity by housing the mice together, implying that obesity in mice actually is contagious (which reminds me of a viral news story from just over a decade ago). In addition to summarizing the paper, @scienceblocks also expresses the frustration that it left many loose ends, creating as many new questions as it answered. (A 10% beneficiary setting has been applied to this post for @scienceblocks.) - Video Friday: Watch Robots Make a Crepe and Twist the Perfect Pretzel - This week, IEEE Spectrum's weekly selection of awesome robot videos includes: A diverse squad of robots from Team CoSTAR (JPL, MIT, Caltech, KAIST, LTU); Ground and aerial robots from Carnegie Mellon and Oregon State University for the DARPA Subterranean Challenge; quadrupeds that can carry you around in a chair, play tug-of-war; tow a minivan; or navigate a maze; a pharmaceutical assembly robot that can produce personalized tablets with medicine for multiple ailments; a dogs' head on a quadruped robot; Competing with wheel chairs, arm and leg prosthetic robots; and more...

Wow, thanks for mentioning and summarizing my post. Also, really liked the link of decade old study you added. I am going to look at it in detail. It sure as hell looks interesting. Once again thanks for reading, sharing and supporting my work. 🙂

You're welcome. And thanks for the interesting article. I have been thinking for a while that there must be some sort of probiotic treatment that would reduce/prevent obesity by cultivating the "right" microbiome, so I think this topic was very interesting, and I'm glad you brought it to my attention.
Really intresting blog bro.
