Despite high vaccine coverage and effectiveness, the incidence of symptomatic infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been increasing in Israel. Whether the increasing incidence of infection is due to waning immunity after the receipt of two doses of the BNT162b2 vaccine is unclear.

As the rollout of vaccines against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)^1,2 is expanding worldwide, data on the durability of protection are limited. A randomized, controlled trial and real-world studies have shown vaccine efficacy of 94 to 95% with the BNT162b2 vaccine (Pfizer–BioNTech) and vaccine effectiveness in preventing symptomatic coronavirus disease 2019 (Covid-19) 7 days or more after receipt of the second dose of vaccine.^1,3–5 Real-world effectiveness and immunogenicity data describing the antibody kinetics over time after vaccination are beginning to appear, but a complete picture of the duration of immunity is not yet available. We recently reported that breakthrough infection in BNT162b2-vaccinated persons was correlated with neutralizing antibody titers.⁶ However, a threshold titer that can predict breakthrough infection has not been defined.

The BNT162b2 vaccine elicits high IgG and neutralizing antibody responses 7 to 14 days after receipt of the second dose. Lower antibody levels have been shown to develop in older persons, men, and persons with an immunosuppressed condition, which suggests that antibody titers in these populations may decrease earlier than in other populations.^7,8 A decrease in anti-spike (S) antibody levels by a factor of two was observed from the peak (at 21 to 40 days) to 84 days after receipt of the second dose of the BNT162b2 vaccine among 197 vaccinated persons.⁹ Here, we report the results of a large-scale, real-world, longitudinal study involving health care workers that was conducted to assess the kinetics of immune response among persons with different demographic characteristics and coexisting conditions throughout the 6-month period after receipt of the second dose of the BNT162b2 vaccine.

If you follow the latest trends in the tech industry, you probably know that there’s been a fair amount of debate about what the next big thing is going to be. Odds-on favorite for many has been augmented reality (AR) glasses, while others point to fully autonomous cars, and a few are clinging to the potential of 5G. With the surprise debut of Amazon’s Astro a few weeks back, personal robotic devices and digital companions have also thrown their hat into the ring.

However, while there has been little agreement on exactly what the next thing is, there seems to be little disagreement that whatever it turns out to be, it will be somehow powered, enabled, or enhanced by artificial intelligence (AI). Indeed, the fact that AI and machine learning (ML) are our future seems to be a foregone conclusion.

Yet, if we do an honest assessment of where some of these technologies actually stand on a functionality basis versus initial expectations, it’s fair to argue that the results have been disappointing on many levels. In fact, if we extend that thought process out to what AI/ML were supposed to do for us overall, then we start to come to a similarly disappointing conclusion.

Analytics has played a significant role in the fight against COVID-19. Would we be as far along in the battle without it?

The COVID-19 pandemic has changed many things in business, producing a new normal that all of us now operate in—and analytics is no exception.

“As companies adapt to the new normal created by COVID, one of the primary questions we’re asked in analytics is how to retrain artificial intelligence (AI) models with a more diverse data set,” said David Tareen, director of AI and analytics at SAS.

There are 40.3 million victims of human trafficking globally, according to the International Labor Organization. Marinus Analytics, a startup based in Pittsburgh, Pennsylvania, hopes to make a dent in that number. The company’s mission is to “serve those working on the frontlines of public safety by developing technology for them to disrupt human trafficking, child abuse, and cyber fraud.” For its achievements, Marinus won $500,000 as part of its third-place ranking in the 2021 IBM Watson AI XPRIZE competition. The startup is the brainchild of three co-founders: Cara Jones, Emily Kennedy, and Artur Dubrawski, who launched it out of the Robotics Institute at Carnegie Mellon University in 2014.

Marinus implements its mission primarily through its set of AI-based tools called Traffic Jam, whose goal is “to find missing persons, stop human trafficking and fight organized crime.”

Traditionally, finding a missing person would involve taping a picture of the person on the computer and then manually combing through thousands, if not millions, of online ads on adult services websites to see if any of the posted pictures match. Such a process is time-consuming and tiring. A human detective’s attention can start flagging after long hours at the computer doing the same task endlessly.

But if you’re in an area already full of Starlink users, don’t expect availability until SpaceX launches more satellites.

SpaceX is doubling the size of its fleet of astronaut-carrying spacecraft — as well as doubling the number of cargo-carrying ones — according to officials who spoke during a briefing ahead of the space company’s next crewed mission later this month.

It’s a significant expansion that will widen SpaceX’s already sizeable head start over the competition.

The White House Office of Science and Technology Policy is developing principles to guard against powerful technologies—with input from the public.

Dr. Hans Recknagel, who led the field and genome research during his Ph.D. and postdoctoral research, said: This was fascinating research, not least because in this species of lizard egg-laying populations still occur and interbreed with live-bearing ones.

Scientists studying the evolution of birth in lizards, from egg-laying to live births, have pinpointed the evolutionary genes from which the species is evolving to ‘build’ a new mode of reproduction.

The study—led by the University of Glasgow and published in Nature Ecology and Evolution —found that a significantly similar amount of the same genes involved in the pregnancy of lizards were shared with other mammals and live-bearing vertebrates.

A FIVE-DAY COURSE of molnupiravir, the new medicine being hailed as a “huge advance” in the treatment of Covid-19, costs $17.74 to produce, according to a report (pdf) issued last week by drug pricing experts at the Harvard School of Public Health and King’s College Hospital in London. Merck is charging the U.S. government $712 for the same amount of medicine, or 40 times the price. (taxpayer funded mind you)

The Covid-19 treatment molnupiravir was developed using funding from the National Institutes of Health and the Department of Defense.
