The US Centers for Disease Control and Prevention (CDC) updated its COVID-19 testing guidelines on Monday. The change, which puzzled many doctors, CDC said it’s no longer recommending testing for most people without symptoms, even if they’ve been in close contact with someone known to have the virus. The CDC did not provide any explanation for the change.

In previous guidelines, the CDC said viral testing was appropriate for people with recent or suspected exposure, even if they were asymptomatic.

Here’s what the CDC website previously said:

“Testing is recommended for all close contacts of persons with SARS-CoV-2 infection. Because of the potential for asymptomatic and pre-symptomatic transmission, it is important that contacts of individuals with SARS-CoV-2 infection be quickly identified and tested.”

The CDC changed the guidelines site on Monday. Here’s what the updated CDC guidelines now say:

“If you have been in close contact (within 6 feet) of a person with a COVID-19 infection for at least 15 minutes but do not have symptoms, you do not necessarily need a test unless you are a vulnerable individual or your health care provider or State or local public health officials recommend you take one.”

Those who don’t have Covid-19 symptoms and haven’t been in close contact with someone with a known infection do not need a test, the updated guidelines say.

“Not everyone needs to be tested,” the agency’s website says. “If you do get tested, you should self-quarantine/isolate at home pending test results and follow the advice of your health care provider or a public health professional.”

Below is an excerpt from the CDC website:

  • If you have been in close contact (within 6 feet) of a person with a COVID-19 infection for at least 15 minutes but do not have symptoms:
    • You do not necessarily need a test unless you are a vulnerable individual or your health care provider or State or local public health officials recommend you take one.
      • A negative test does not mean you will not develop an infection from the close contact or contract an infection at a later time.
    • You should monitor yourself for symptoms. If you develop symptoms, you should evaluate yourself under the considerations set forth above.
    • You should strictly adhere to CDC mitigation protocols, especially if you are interacting with a vulnerable individual. You should adhere to CDC guidelines to protect vulnerable individuals with whom you live.
  • If you do not have COVID-19 symptoms and have not been in close contact with someone known to have a COVID-19 infection:
    • You do not need a test.
      • A negative test does not mean you will not contract an infection at a later time.
    • If you decide to be tested, you should self-isolate at home until your test results are known, and then adhere to your health care provider’s advice. This does not apply to routine screening or surveillance testing at work, school, or similar situations.

The CDC guidelines still say people should get tested if they have symptoms and that someone’s health care provider “may advise a COVID-19 test.”

“It is important to realize that you can be infected and spread the virus but feel well and have no symptoms,” the updated CDC site says, noting that local public health officials might request asymptomatic “healthy people” be tested, depending on cases and spread in an area.

In its pandemic planning scenarios, the CDC says its current best estimate is that 40% of infections are asymptomatic and 50% of transmission occurs before symptoms occur.

In the Summary of Changes section on its website, CDC said the August 24 changes apply to: “Diagnostic testing categories have been edited to focus on testing considerations and actions to be taken by individuals undergoing testing.”

Cyber hacking has become one of the fastest rising threats to organizations of all sizes. According to a study, the damage from cybercrime is projected to cost $6 trillion annually by 2021. Earlier this month, we wrote about Facebook after a data breach exposed massive phishing and credit card fraud operation targeting 100,000s Facebook users in just three months.

Facebook is not alone. Over the weekend, Brian Krebs at KrebsOnSecurity, wrote a piece about a recent attack on cryptocurrency services via GoDaddy, the world’s largest domain name registrar. The attack, which was launched through GoDaddy employees, is a reminder that no organization is immune to cyber hacking.

According to Krebs, the hackers pulled off the attack after they redirected email and web traffic destined for several cryptocurrency trading platforms over the past week. The attacks were facilitated by scams targeting employees at GoDaddy. In at least two incidents, it appears that the hackers were able to either transfer a domain to another account and modify its nameservers or otherwise modify nameservers on the domain names. Krebs said:

The incident is the latest incursion at GoDaddy that relied on tricking employees into transferring ownership and/or control over targeted domains to fraudsters. In March, a voice phishing scam targeting GoDaddy support employees allowed attackers to assume control over at least a half-dozen domain names, including transaction brokering site escrow.com.

And in May of this year, GoDaddy disclosed that 28,000 of its customers’ web hosting accounts were compromised following a security incident in Oct. 2019 that wasn’t discovered until April 2020. This latest campaign appears to have begun on or around Nov. 13, with an attack on cryptocurrency trading platform liquid.com.

“A domain hosting provider ‘GoDaddy’ that manages one of our core domain names incorrectly transferred control of the account and domain to a malicious actor,” Liquid CEO Mike Kayamori said in a blog post. “This gave the actor the ability to change DNS records and in turn, take control of a number of internal email accounts. In due course, the malicious actor was able to partially compromise our infrastructure, and gain access to document storage.”

In the early morning hours of Nov. 18 Central European Time (CET), the cyptocurrency mining service NiceHash discovered that some of the settings for its domain registration records at GoDaddy were changed without authorization, briefly redirecting email and web traffic for the site.

NiceHash immediately froze all wallet activity to secure all user’s funds. The company said that “all funds are safe and users will get access to their wallets in the next 24 hours.” In a blog post, NiceHash said:

“To secure all user’s funds, we have immediately frozen all wallet activity. All funds are safe and users will get access to their wallets in the next 24 hours. NiceHash domain is now back online and all systems are fully operational with the exception of all withdrawals. Withdrawals will resume after the internal audit. At this moment in time, it looks like no emails, passwords, or any personal data were accessed but we do suggest resetting your password and activate 2FA security.”

We first covered Relativity Space back in 2018 after the Los Angeles-based orbital launch startup raised $35 million in funding. A lot has changed since then. Relativity Space (Relativity) is disrupting 60 years of aerospace tradition by creating an entirely new process to build and fly rockets. Its 3-D print technology enables rockets to be built and flown in days instead of years. Its 3-D printed rocket contains 100 times fewer parts than the conventional rockets.

Relativity deploys and resupplies satellite constellations, is the first company to 3D print an entire rocket, and build the largest metal 3D printers in the world. Its new process to build and fly rockets is redefining how we access to space to connect our planet.

Today, Relativity announced it closed a $500 million Series D equity funding round to accelerate its planned initiatives, including its factory of the future, launch vehicle development, and 3D printing technologies as it builds toward humanity’s multi-planetary future.

The round, which further validates Relativity’s sector-leading momentum across commercial execution, technical milestones, and talent growth, was led by Tiger Global Management with participation from new investors Fidelity Management & Research Company LLC, Baillie Gifford, ICONIQ Capital, General Catalyst, XN, Senator Investment Group, and Elad Gil. Existing investors participating in the round include BOND, Tribe Capital, K5 Global, 3L, Playground Global, Mark Cuban, Spencer Rascoff, and Allen & Company LLC, among others.

Since founded in 2015, Relativity has built the world’s largest metal 3D printer and completed over 100 rocket engine test fires on their quest to build their own rocket constructed almost entirely of 3D printed parts, which goes beyond just cubesats. The custom-built rockets launch Earth-orbiting satellites with large payloads (i.e. a satellite the size of a small car), six times the size of its competitors’ abilities.

Relativity’s radically simplified supply chain enables the company to build its orbital rocket, Terran 1, with 100x fewer parts in less than 60 days. By fusing 3D printing, artificial intelligence, proprietary software, and autonomous robotics, Relativity’s team is creating an entirely new value chain for aerospace, starting with an orbital launch.

“This past year drove change in every industry, including aerospace. Throughout 2020, Relativity achieved unprecedented growth, attracted top talent, and stepped up to deliver results we could have only imagined when we started the company less than five years ago,” shared Tim Ellis, Relativity’s co-founder and CEO. “We are on track to launch our first Terran 1 rocket to orbit next year with existing capital on our balance sheet. With this new Series D funding, we will now dramatically accelerate the development of our long-term plans and look beyond the first launch.”

Relativity stands apart from other launchers in the space by not just employing 3D printing as a supplemental technique, but for over 95% of major components. Using machine learning in combination with their custom software, hardware, and proprietary metal alloys, Relativity has cut rocket part count from 100,000 to 1,000 and dramatically reduced labor and timelines by orders of magnitude.

Relativity’s process disrupts the entire tech stack from design algorithms, supply chain, inventory management, quality control, and the very way raw materials form themselves into complex aerospace products. It is this ingenuity that will save millions of dollars for each of Relativity’s customers at every launch.

Relativity Space is backed by leading investors including Baillie Gifford, BOND, Fidelity, General Catalyst, ICONIQ Capital, K5 Global, Mark Cuban, Playground Global, Social Capital, Tiger Global, Tribe Capital, Y Combinator, and 3L.

Gibraltar, Gibraltar, November 23, 2020 — Gnosis, a blockchain prediction market, has announced the launch of its futarchy-based governance organization named GnosisDAO.

Created to transparently guide decisions on development, investments, and governance, the prediction market-driven collective is a major milestone in the development of modern electronic prediction markets. The project enables permissionless prediction markets by taking the form of a minimum viable futarchy network, controlled and managed by users.

Futarchy is an ideologically neutral system of governance proposed by economist Robin Hanson, wherein market speculators get to determine policies. For example, if wagers were to be placed on the question “Should the minimum wage be above $20?” the subsequent policy would reflect whichever answer received the most bets. The idea behind futarchy is that people vote values but bet beliefs.

“The launch of GnosisDAO is about tapping into public expertise, and returning power—and transparency—to the people,” said Gnosis CEO Martin Köppelmann.

Members of the Gnosis community are invited to submit their own proposals via the Gnosis Forum, with markets forming around whatever topic members deem interesting and GnosisDAO covering the funding.

“As the prediction market industry’s first futarchy-governed organization, we are immensely proud to set the standard and raise expectations around the running of such platforms going forward,” added Köppelmann.

Prediction markets have long been viewed as an alternative to traditional media in understanding sentiment around key world events. Wagers placed on betting marketing aggregators recently favored Democratic Presidential hopeful Joe Biden over incumbent President Donald Trump, with Biden subsequently claiming victory and online prediction markets have proliferated in recent years with bets placed on a variety of subjects.

The team behind Gnosis has spent years developing the technical building blocks behind other prediction markets, not least the Omen platform which saw over $1 million worth of wagers placed on the latest Presidential election.

About Gnosis

Gnosis is one of the first companies to build on Ethereum, having been founded in 2015 by Martin Köppelmann and Stefan George as part of ConsenSys, the globally leading Ethereum venture production studio. In April 2017, Gnosis raised funds and spun out of ConsenSys to become an independent company. Gnosis offers three leading product lines (prediction markets, DEXs, multisig platform) allowing users to securely create, trade, and hold crypto assets.
