“The most extensive travel restrictions to stop an outbreak in human history haven’t been enough. We analyzed the movements of hundreds of millions of people to show why.”

“A group of former IMF chief economists warned last weekend that a global recession had already begun, but although economic activity is slowing sharply, much official data are out of date before they are even published, given the time they take to collate. To make up for the lack of official information, the FT has compiled a set of alternative, high-frequency measures of economic activity for different sectors which give an early indication of what to expect when official data start to become available in the coming weeks. ”

“At the time of writing, the coronavirus disease of 2019 remains a global health crisis of grave and uncertain magnitude. To the non-expert (such as myself), contextualizing the numbers, forecasts and epidemiological parameters described in the media and literature can be challenging.
Gabriel Goh created this calculator as an attempt to address this gap in understanding. This calculator implements a classical infectious disease model — SEIR (Susceptible → Exposed → Infected → Removed), an idealized model of spread still used in frontlines of research e.g. [Wu, et. al, Kucharski et. al].”

“About 100M public messages have been collected and analyzed to understand the digital response in online social media to COVID-19 outbreak. Specifically, we used machine learning techniques to quantify: collective sentiment & psychology: lexicon-based and rule-based emotional and psychological state social bot pollution: The fraction of activities due to social bots and the exposure of the Twitterverse to unreliable news News reliability: the fraction of URLs pointing to reliable news and scientific sources”

“This phylogeny shows evolutionary relationships of hCoV-19 (or SARS-CoV-2) viruses from the ongoing novel coronavirus COVID-19 pandemic. This phylogeny shows an initial emergence in Wuhan, China, in Nov-Dec 2019 followed by sustained human-to-human transmission leading to sampled infections. Although the genetic relationships among sampled viruses are quite clear, there is considerable uncertainty surrounding estimates of transmission dates and in reconstruction of geographic spread. Please be aware that specific inferred transmission patterns are only a hypothesis.”

“We are not epidemiologists—we are the design, engineering, and support teams at a mapping company. Just as we don’t spend every moment thinking about how to track and slow the spread of infectious disease, most public health teams we work with are not experts in spatial data visualization. In the environment of a growing epidemic, maps have a way of spreading fast, too — making it imperative that they are accurate, informative, and thoughtfully designed. To answer common questions and help our partners make thoughtful design decisions while mapping this and other health crises, we have put together a number of best practices and common pitfalls to avoid.”

“We’re exploring ways that aggregated anonymized location information could help in the fight against COVID-19. One example could be helping health authorities determine the impact of social distancing, similar to the way we show popular restaurant times and traffic patterns in Google Maps”
“A medical device manufacturer has threatened to sue a group of volunteers in Italy that 3D printed a valve used for life-saving coronavirus treatments. The valve typically costs about $11,000 from the medical device manufacturer, but the volunteers were able to print replicas for about $1”
“We recently discovered a new strain of Android malware. The Trojan (detected as: Trojan-Spy.AndroidOS.Cookiethief) turned out to be quite simple. Its main task was to acquire root rights on the victim device, and transfer cookies used by the browser and Facebook app to the cybercriminals’ server. This abuse technique is possible not because of a vulnerability in Facebook app or browser itself. Malware could steal cookie files of any website from other apps in the same way and achieve similar results.”

“For well over a decade, identity thieves, phishers, and other online scammers have created a black market of stolen and aggregated consumer data that they used to break into people’s accounts, steal their money, or impersonate them. In October, dark web researcher Vinny Troia found one such trove sitting exposed and easily accessible on an unsecured server, comprising 4 terabytes of personal information—about 1.2 billion records in all.”
