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 A preliminary study that has not yet been peer-reviewed did find that a test that specifically targets the anti-spike antibodies the vaccines trigger may be helpful in determining whether the vaccine worked.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?

u.s. capitol building insurrection

Screen Shot 2021 01 17 at 7.42.47 PMWhen Donald Trump stood before his followers on Jan. 6, 2021 and urged them to march on the United States Capitol, he was doing what he had always done. He never took electoral democracy seriously nor accepted the legitimacy of its American version. Even when he won, in 2016, he insisted that the election was fraudulent — that millions of false votes were cast for his opponent. In 2020, in the knowledge that he was trailing Joseph R. Biden in the polls, he spent months claiming that the presidential election would be rigged and signaling that he would not accept the results if they did not favor him. He wrongly claimed on Election Day that he had won and then steadily hardened his rhetoric: With time, his victory became a historic landslide and the various conspiracies that denied it ever more sophisticated and implausible.

 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.
