 This Fight is Yours

They were two young Jewish men who grew up just a few years apart in the New York area during the Great Depression, and though they were both drawn to the study of medicine and did not know each other at the time, their names would, years later, be linked in a heroic struggle that played out on the front pages of newspapers around the world. In the end, both Albert Sabin and Jonas Salk could rightfully claim credit for one of humanity’s greatest accomplishments—the near-eradication of polio in the 20th century. And yet debate still echoes over whose method is best suited for the mass vaccination needed to finish the job: Salk’s injected, dead-virus vaccine or Sabin’s oral, live-virus version.

vaccines to tye world

A third dose has been shown to help in these cases. In one study, one-third of solid organ transplant patients who had a suboptimal response to two doses of the Pfizer or Moderna vaccines were able to develop an antibody response with a third dose. Those who are immunocompromised may wonder if the vaccine they received is successfully generating immunity in their body. A preliminary study that has not yet been peer-reviewed did find that a test that specifically targets the anti-spike antibodies the vaccines trigger may be helpful in determining whether the vaccine worked. But for now, the FDA does not recommend antibody tests to assess immunity.

 the Phoenix Reborn

The disappearance of the Mayan Empire is all the more mysterious because it happened not once, but twice. The earliest civilization that took root during the heart of antiquity prospered for hundreds upon hundreds of years, with innovations that rivaled those of Egypt. Unlike the Egyptians and Mesopotamians, however, the Mayans grew their population on the back of corn, beans, squash, and chiles, rather than wheat. Even so, they began building the first of their grand temples before they would vanish, but what was the cause of the end of this empire?

 For heart transplant centers accessibility may matter as much as quality 1

BALTIMORE – In a first-of-its-kind surgery, a 57-year-old patient with terminal heart disease received a successful transplant of a genetically-modified pig heart and is still doing well three days later.

 1 Golden orb weaver Nephila eduliso 1 2

Doctoral student Amir Haluts is researching the unusual and dangerous sex lives of golden orb-weaver spiders.  Imagine a two-dimensional enclosed space, where a murderous female ruler sits in the center. Contestants are thrown into the ring, and they seem puny compared to her, but one of them manages to overcome his competitors to maneuver in behind her without her noticing, and wins the right to potentially mate with her. This could be the plot of a bloody reality show – or a Squid Game challenge – but it's actually the way of life of the golden orb-weaver spiders (Trichonephila), common in Africa, South America and the Far East.
