Abcam prices

When a vendor of important reagents like antibody supplier Abcam charges big money, those high Abcam prices could negatively impact research in the long run. Some of the prices are so high that buying just a few antibodies could take up a small but meaningful slice of an entire R01 grant. Sky-high Abcam prices I’ve […]

Perspectives 10 years after STAP cells: the culture of science, misconduct, & hopes for progress

Haruko-Obokata-小保方-晴子-

Exactly ten years ago today, on January 29, 2014, I wrote about two new Nature papers on so-called STAP cells. The papers claimed that stress alone could convert regular non-stem cells into some of the most powerful stem cells. More specifically, the authors claimed to make pluripotent stem cells similar to iPS cells this way.

4th Obokata retraction after Harvard investigation: STAP saga finally over?

si-Haruko

Retraction Watch broke the news that Haruko Obokata of the STAP cell train wreck now has a 4th paper retraction. The publication related to the controversial idea that adult tissues have pluripotent potential or actual pluripotent stem cells in them so it was kind of foundational for the debunked STAP cell idea. It also reminds

Whatever happened to the STAP cell scientists including Haruko Obokata?

Obokata-game

Once upon a time this blog and major outlets around the world were regularly writing about a Japanese stem cell researcher named Haruko Obokata (小保方 晴子). Whatever happened to Obokata and the other folks directly involved in STAP cell research? First, a bit of background because maybe still a few people never heard of STAP cells

STAP cells (stap細胞) are real deal says new Vacanti patent declaration

Vacanti-STAP-figure-2017

STAP is back? Really? No, I don’t believe so, but there’s an interesting development and twist on the STAP cell front. Just a few days ago on January 4, 2017 Dr. Charles Vacanti, the originator of the STAP cells concept, submitted a declaration to the USPTO affirming the belief that STAP cells are real and requesting that

Haruko Obokata (小保方 晴子) website posts dubious STAP cell validation data

STAP-cell-Obokata-2016

Haruko Obokata is most well-known for her role as first author of the now retracted two STAP cell Nature papers. These manuscripts claimed to have made pluripotent and even totipotent stem cells simply by stressing cells out with acid treatment or in other ways. Nobody else could get this method to work to create the so-called

Weekend reads: sperm, stem cells, chimeras, STAP, DNA Apps

sperm-and-egg

Here are some cool science reads to enjoy this weekend. Lab-grown sperm made from stem cells can’t swim, but are able to fertilize eggs, reports Eric Boodman over at STAT. Mouse-human neural crest chimeras: Not only a matter of black and white. Clever title. Antonio Regalado writes about a DNA App Store coming soon to a
