1. Big news in regenerative medicine this week: scientists have grown the first working organ in a lab (a functional thymus was generated from reprogrammed fibroblast cells).
2. It sounds fishy, but zebrafish are helping scientists study potential mechanisms underlying Alzheimer’s disease.
|Zebrafish are excellent model systems that help scientists learn about development and disease|
3. Another interesting development for Alzheimer’s disease this week. Studies have revealed that infusing the blood of young mice into older mice reverses some of the aging process. Physicians will soon be testing if blood plasma from people under 30 can alleviate the symptoms of Alzheimer’s.
|Sorry, Barnabas, but drinking the blood does not work.|
4. Better science, better pizza. Scientists set out to “quantify the pizza baking properties and performance of different cheeses”, and the results are described here. Have they found the perfect combination of cheeses? I look forward to trying…
5. Time for a coffee break? No doubt you are familiar with the trademark “coffee ring” that results from spilled coffee, which decorated many of the journal articles I read back when we used to print them out. Based on this study, the video below shows coffee particles in action, forming that characteristic ring.
Science quote of the week:
“Nothing in life is to be feared, it is only to be understood. Now is the time to understand more, so that we may fear less” --Marie Curie
