Alberta excrement being tested for COVID-19 as researchers refine sewage surveillance
“The logistics of clinical testing don’t let you sample everybody, but sewage does sample everybody.”-Steve Hrudey.
Raw sewage being flushed into Alberta’s municipal wastewater plants could help public health officials better track — and predict — the spread of COVID-19.
A team of Alberta scientists has joined a growing international effort to sample wastewater for traces of SARS-CoV-2, the virus responsible for the disease.
Think Big, Move Fast, Build Capacity and Resilience: Disaster Management
The future of disaster management, using artificial intelligence, machine learning, and a bit of Waffle House and Starbucks 🙂
Ira Pastor, ideaXme life sciences ambassador interviews Craig Fugate Chief Emergency Management Officer of One Concern and former administrator of the Federal Emergency Management Agency (FEMA).
The international context of this interview: In choosing our leaders it is becoming increasingly important to select people who can both anticipate and address and where possible avoid large scale disasters. Here, Craig Fugate discusses evaluating past disasters, planning for future events and reacting to the “unexpected” — “think big and move fast”.
Ira Pastor comments:
The U.S. has sustained 279 weather and climate disasters since 1980 where overall damages/costs reached or exceeded $1 billion (including CPI adjustment to 2020). The total cost of these 279 events exceeds $1.825 trillion.
What Martian Settlers Need to Know About Soil Can Teach us How to Grow Better on Earth
Article from Universetoday. Interesting read.
When human beings start living in space for extended periods of time they will need to be as self-sufficient as possible. The same holds true for settlements built on the Moon, on Mars, and other bodies in the Solar System. To avoid being entirely dependent on resupply missions from Earth (which is costly and time-consuming) the inhabitants will need to harvest resources locally – aka. In-Situ Resource Utilization (ISRU).
This means they’ll have to procure their own sources of water, building materials, and grow their own food. While the ISS has allowed for all kinds of experiments involving hydroponics in space, little has been done to see how soil fares in microgravity (or lower gravity). To address this, Morgan Irons – Chief Science Officer of the Virginia-based startup Deep Space Ecology (DSE) – recently sent her #id=8305″] Soil Health in Space experiment to the ISS.
The experiment, Determination of Gravitational Effects on Soil Stability for Controlled Environment Agriculture, was sponsored through Morgan’s fellowship with the Norfolk Institute – which provided grant funding from numerous companies (including DSE). An agreement between Norfolk Institute and Rhodium Scientific, LLC (an official space-flight implementation partner of the ISS U.S. National Laboratory) provided access to the NASA launch opportunities and the ISS.
Multifunctional skin-mounted microfluidic device able to measure stress in multiple ways
An international team of researchers has developed a multifunctional skin-mounted microfluidic device that is able to measure stress in people in multiple ways. In their paper published in Proceedings of the National Academy of Sciences, the group describes their device and how it could be useful.
Prior research has shown that long-term stress can damage a person’s health. It can lead to diabetes, depression, obesity and a host of other problems. Some have suggested that one of the ways to combat stress is to create a means for alerting a person to their heightened stress so that they might take action to reduce it. To that end, prior teams have developed skin-adhesive devices that that collect sweat samples. The tiny samples contain small amounts of cortisol, a hormone that can be used as a marker of stress levels. In this new effort, the researchers have improved on these devices by developing one that measures more than just cortisol levels and is much more comfortable.
The researchers began with the notion that in order to convince people to wear a device full time, it had to be both useful and comfortable. The solved the latter issue by making their device out of soft materials that adhere gently to the skin. They also used a skeletal design for their microfluidic sweat-collection apparatus—a flexible mesh. They also added more functionality. In addition to cortisol, their device is able to measure glucose and vitamin C levels. They also added electrodes underneath that are able to measure sweat rate and electrical conductivity of the skin, both of which change in response to stress. They also added a wireless transmitter that sends all of the data to a nearby smartphone running the device’s associated app.
The Deck Is Not Rigged: Poker and the Limits of AI
Tuomas Sandholm, a computer scientist at Carnegie Mellon University, is not a poker player—or much of a poker fan, in fact—but he is fascinated by the game for much the same reason as the great game theorist John von Neumann before him. Von Neumann, who died in 1957, viewed poker as the perfect model for human decision making, for finding the balance between skill and chance that accompanies our every choice. He saw poker as the ultimate strategic challenge, combining as it does not just the mathematical elements of a game like chess but the uniquely human, psychological angles that are more difficult to model precisely—a view shared years later by Sandholm in his research with artificial intelligence.
“Poker is the main benchmark and challenge program for games of imperfect information,” Sandholm told me on a warm spring afternoon in 2018, when we met in his offices in Pittsburgh. The game, it turns out, has become the gold standard for developing artificial intelligence.
Tall and thin, with wire-frame glasses and neat brow hair framing a friendly face, Sandholm is behind the creation of three computer programs designed to test their mettle against human poker players: Claudico, Libratus, and most recently, Pluribus. (When we met, Libratus was still a toddler and Pluribus didn’t yet exist.) The goal isn’t to solve poker, as such, but to create algorithms whose decision making prowess in poker’s world of imperfect information and stochastic situations—situations that are randomly determined and unable to be predicted—can then be applied to other stochastic realms, like the military, business, government, cybersecurity, even health care.
How Indonesia is pushing medtech and insurtech as part of AI drive
Online health care and medtech AI have risen in prominence in the country as the government seeks more equal access to medicines and treatment for its citizens, spread across a vast land mass. The urgency has been heightened by the impact from Covid-19 – with Indonesia recently overtaking the Philippines as the hardest-hit country in Southeast Asia.
Indonesia’s fast-growing manufacturing sector also presents opportunities for medtech innovation as well as research and development.
Microbes of the Universe — Could our Solar System be rife with Pathogens?
In a recent study of the upper atmosphere of Venus, finding the chemical fingerprint of phosphine has led to speculation that it may be tied to airborne life high in the clouds of our sister planet [1]. We harbour similar suspicion of microbial life on Mars [2], Saturn’s moon Enceledus [3], and Europa, the icy Galilean of the Jovian system [4]. The dwarf planet Ceres of the asteroid belt could be added to that list also, with recent evidence of oceanic water [5], while more exotic variations of life may exist on Titan, which is known to be teeming with organic materials [6]. Should we be more wary of our Solar System as an environment to explore, and the potential of pathogens we may encounter?
If one rewinds 500 years, to when exploration of new worlds involved sailing the oceans, the discovery of the Americas introduced viruses which decimated the native population at that time [7]. That in itself was far from a unique event in history, of course. There have been many occurrences throughout history where travel between distant lands has resulted in the introduction of devastating plagues to one population or the other — not least the Black Death, which arrived in Europe from commercial travel with Asia in the 1300s [8]. Meanwhile, 2020 has reminded us how a novel virus can prove virtually unstoppable from spreading worldwide in a matter of months and reaching pandemic level, once introduced to our now interconnected world [9].
Indeed when the first astronauts returned from the Moon in the 60s, they had to undergo weeks of quarantine as a precaution against introducing a lunar pathogen to Earth [10]. We now know the Moon to be a sterile world, but this should not give us a false sense of security when visiting and returning from other worlds, which are far more likely to harbour microbial life. It is quite plausible to consider that any microbes which have evolved to survive in the harsh environments on other worlds could multiply out of control if introduced to a more fertile environment on Earth. The likelihood of any such foreign microbes being capable of becoming infectious pathogens to our species is difficult to measure, but one could still cause problems regardless, by undermining Earth’s ecosystem in competing with native microbial life as a runaway invasive species.
Fortunately, due to the vast distances involved in inter-planetary travel, returning astronauts would likely show symptoms of infection from any dangerous pathogen long before reaching home, as such a journey would be expected to take many months, even with more advanced propulsion technology than we use in space travel today. That is not to say they could not inadvertently return with microbial life on board — or even on the exterior of craft: Earth’s tardigrades, for example, have proven quite durable in journeys into outer space [11].
French Court Asks Microsoft for Safeguards Against U.S. Surveillance of Health Data
U.S. company can keep hosting vast coronavirus-related project but must protect French citizens’ health data from American government, court rules.
A French court has ruled that Microsoft Corp. can continue hosting a government-run project aggregating citizens’ anonymous health data to use for AI-based research, but must guarantee no data will be sent to the U.S. or be shared with American intelligence authorities.
The ruling, handed down last week, contradicts the stance of France’s data protection authority, which told the court this month that any U.S. cloud provider could be forced to comply with U.S. surveillance laws and should therefore not be allowed to host sensitive health data. The regulator’s opinion could provide clues for other companies handling such data, legal experts say.
Companies are wrestling with tricky decisions about moving their data from the European Union to the U.S., following a court decision this summer that required personal data transferred there to include special guarantees against surveillance by the American government.
Can We Trust AI Doctors? Google Health and Academics Battle It Out
So now, there are AI doctors.
Machine learning is taking medical diagnosis by storm. From eye disease, breast and other cancers, to more amorphous neurological disorders, AI is routinely matching physician performance, if not beating them outright.
Yet how much can we take those results at face value? When it comes to life and death decisions, when can we put our full trust in enigmatic algorithms—“black boxes” that even their creators cannot fully explain or understand? The problem gets more complex as medical AI crosses multiple disciplines and developers, including both academic and industry powerhouses such as Google, Amazon, or Apple, with disparate incentives.
This week, the two sides battled it out in a heated duel in one of the most prestigious science journals, Nature. On one side are prominent AI researchers at the Princess Margaret Cancer Centre, University of Toronto, Stanford University, Johns Hopkins, Harvard, MIT, and others. On the other side is the titan Google Health.
