In the comics and films, Clark Kent wore reading glasses while Superman had no glasses but sported a lock of hair on his forehead - and no one figured it out. Ridiculous, it was later said.

Perhaps it was ridiculous if keen reporters who knew Kent well did not figure it out, but for the most part even subtle disguises work well for most people, according to a new study. Something as minor as complexion changes or a hairstyle are enough to convince people that in a world of six billion people, a one in a million chance of seeing a person who looks like someone you know is not that bad.
Cockroaches have a reputation for resilience, likely contributing to the belief that they could even survive a nuclear bomb and subsequent radiation exposure.

And though Fukushima was not a nuclear bomb, or even a real disaster (more people died trying to escape than from radiation), the claim that cockroaches were found led weight to their constitutions.(a) But is it really accurate? In the future, if a disgraced doctor finds Alita: Battle Angel in a junk pile, will she be with a cockroach? 

In vitro, in utero, these are science terms that have become commonly known. In vitro means studies in cells, like using test tubes, or a test for a fetus in the womb in the case of in utero.

Studies done in feces - yes, excrement - haven't really had a name, they though are common in gut bacteria analyses. Now they might, thanks to UNC School of Medicine scientist Aadra Bhatt, PhD, and colleagues; in fimo. Their proposal is published in the journal Gastroenterology.

An immune checkpoint molecule, SA-4-1BB developed for cancer immunotherapy also protects against future development of multiple types of cancer when administered by itself, shows a new study.

The recombinant protein molecule SA-4-1BBL has been used to enhance the therapeutic efficacy of cancer vaccines with success in pre-clinical animal models. It accomplishes this by boosting the effectiveness of CD8+ T cells, adaptive immune cells trained to target the tumor for destruction. When the researchers treated normal healthy mice with SA-4-1BBL alone, the mice were protected when the researchers later exposed them to different types of tumor cells.

Patrolling the body instead of generating an immune response after the tumor is present

Cellular barcoding has been used to tag, track and pinpoint cells responsible for the spread of breast cancer from the main tumor into the blood and other organs, and also revealed how chemotherapy temporarily shrinks the number of harmful cells, rather than eliminating them, explaining how the cancer could eventually relapse.

Pinpointing the 'seeders' of disease

Most deaths from breast cancer are caused by the metastasis, or spread, of cancerous cells from the main tumor site into other organs. 

Exposure to glyphosate — at 45 years of age the world’s most widely used, broad-spectrum herbicide and the primary ingredient in the weedkiller Roundup — increases the risk of some cancers by more than 40 percent, according to a meta-analysis published in the online journal Mutation Research/Reviews in Mutation Research, an imprint of publishing giant Elsevier.
