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.

Scientists also analysed microbial genetic material from the stool of men with prostate cancer and identified a specific bacterium – Ruminococcus – that may play a major role in the development of resistance. In contrast, the bacterium Prevotella stercorea was associated with favourable clinical outcomes.

Common gut bacteria can fuel the growth of prostate cancers and allow them to evade the effects of treatment, a new study finds.

Tesla Giga Shanghai has officially exceeded the Fremont Factory’s output, according to Elon Musk’s calculations. As Tesla’s main export hub, Giga Shanghai’s output will play a significant role in the company’s global growth.

“We have three new factories. Giga Shanghai has done an incredible job. And Giga Shanghai now exceeds Fremont in production,” Musk announced at the 2021 Annual Shareholders Meeting.

Musk pointed out that Tesla Giga Shanghai took roughly 11 months to build and reached full volume production a year later. Since Giga Shanghai started operations, Tesla’s production and delivery numbers have noticeably increased.

Specialized cells that conduct electricity to keep the heart beating have a previously unrecognized ability to regenerate in the days after birth, a new study in mice by UT Southwestern researchers suggests. The finding, published online in the Journal of Clinical Investigation, could eventually lead to treatments for heart rhythm disorders that avoid the need for invasive pacemakers or drugs by instead encouraging the heart to heal itself.

“Patients with arrhythmias don’t have a lot of great options,” said study leader Nikhil V. Munshi, M.D., Ph.D., a cardiologist and Associate Professor of Internal Medicine, Molecular Biology, and in the Eugene McDermott Center for Human Growth and Development. “Our findings suggest that someday we may be able to elicit regeneration from the heart itself to treat these conditions.”

Dr. Munshi studies the cardiac conduction system, an interconnected system of specialized heart muscle cells that generate electrical impulses and transmit these impulses to make the heart beat. Although studies have shown that nonconducting heart muscle cells have some regenerative capacity for a limited time after birth—with many discoveries in this field led by UTSW scientists—conducting cells called nodal cells were largely thought to lose this ability during the fetal period.
