New blood test can detect 50 types of cancer - System uses machine learning to offer new way to screen for hard-to-detect cancers

Date Published: Fri, 3 Apr 2020 15:37:29 +0200

A new blood test that can detect more than 50 types of cancer has been revealed by researchers in the latest study to offer hope for early detection.

The test is based on DNA that is shed by tumours and found circulating in the blood. More specifically, it focuses on chemical changes to this DNA, known as methylation patterns. Researchers say the test can not only tell whether someone has cancer, but can also shed light on the type of cancer they have.

Dr Geoffrey Oxnard of Boston’s Dana-Farber Cancer Institute, part of Harvard Medical School, said the test was now being explored in clinical trials. “You need to use a test like this in an independent group at risk of cancer to actually show that you can find the cancers, and figure out what to do about it when you find them,” he said.

Manitoba researchers say they may have found a way to safely reuse N95 masks amid COVID-19 crisis - using existing autoclaving machines

Date Published: Fri, 3 Apr 2020 15:18:43 +0200

"The assumption has been that if you tried this on an N95 mask they would degrade rapidly. We thought we'd give it a try anyway," Kumar said.

"And actually what we found is while it does degrade some [types of] masks, there's a certain group of masks that are made of kind of a fabric-type material, rather than being moulded closely to the face… they're called pleated [masks]," he said. Kumar said the pleated fabric masks can be cycled through an autoclaving machine 10 times and come out as good as before.

"The reason this is really important is that autoclaves are available at literally every established hospital in the world. There is probably no hospital in the world that doesn't have an autoclave machine," Kumar said.

Wootware can sell PC hardware online during South Africa’s coronavirus lockdown

Date Published: Fri, 3 Apr 2020 14:12:53 +0200

Wootware has re-opened its online store and is able to deliver computer hardware in South Africa.

“We’ve been issued an operating permit by government and will continue processing and dispatching orders during the shutdown period,” the Wootware website states.

Of course what I am looking for is not in stock and there is some doubt about when they will receive new stock.

Oura Ring arrived today - will be monitoring my temperature, respiration and heartrate variability and comparing to my Fitbit Charge 2

Date Published: Fri, 3 Apr 2020 12:23:19 +0200

An Oura Ring is a biotracker's dream device as it measures so many biological indicators. It does its main readings at night while you are sleeping and during the day is working like a basic Fitbit tracker. There are activities you can trigger in the day for measurement such as meditation. It establishes a baseline for a person and then looks at variations that happen over time.

I remember when I was hospitalised a few years ago with a high fever, that I noticed my Fitbit had detected a rising resting heartrate but that was all Fitbit was detecting. I still think the newest Fibit Charge 4 has missed out on a major opportunity to measure additional indicators such as temperature and respiration. Now was the time...

So I'll establish my baselines and do some comparisons against the Fitbit over the coming week. I have also volunteered to participate in the University of California's project which is looking at improving the algorithms for the Oura Ring to help early detection of COVID-19 illness symptoms so for this I must fill in a daily survey and if I (when?) I get COVID-19 the readings from my ring will assist them with this.

The South African Presidency has approached OfferZen to help organise South Africa’s tech community to contribute in the fight against COVID-19

Date Published: Thu, 2 Apr 2020 13:48:10 +0200

This comes after University of Pretoria professor Willem Fourie contacted OfferZen co-founder Malan Joubert to help find developers to build a map identifying the communities in South Africa that are most vulnerable to the coronavirus.

“Based on this conversation, the government realised how critical it will be to collaborate with local tech companies and developers in this time of crisis. They have officially asked OfferZen to mobilise the tech industry to help,” said Joubert.

OfferZen is therefore inviting members of the South African tech community to pitch in and help with projects they have identified.

LineageOS 17.1 based on Android 10 is now officially available - If your phone no longer gets OEM Updates you may want to consider LineageOS

Date Published: Thu, 2 Apr 2020 10:35:40 +0200

If you call yourself a custom ROM veteran, you definitely have heard about LineageOS. LineageOS traces its roots back to CyanogenMod, the custom ROM that became popular on the HTC Dream/T-Mobile G1, the first Android smartphone available for purchase. CyanogenMod, in turn, went on to become one of the most popular custom ROMs available across a plethora of devices, and several of the key developers and maintainers of the project went on to establish LineageOS when Cyanogen decided to stop supporting CyanogenMod. LineageOS picked up the reins with LineageOS 13.0 and LineageOS 14.1 releases, and the project has continued along over the years. Now, LineageOS is marking its major version bump up to LineageOS 17.1 with Android 10 as the base.

I've always found LineageOS contains a few extra useful bells and whistles too to moving to it is often a step up for most phones. You do just want to check your phone is officially supported and read the support thread for your phone to see what other user's experiences are.

Researchers to study if startup’s wrist-worn wearable can detect early COVID-19 respiratory issues - Will Fitbit be left behind?

Date Published: Wed, 1 Apr 2020 18:30:20 +0200

The data to be used for this study has been collected from WHOOP’s 3.0 hardware, which has also recently been validated by a University of Arizona external study conducted specifically to determine the accuracy of its measurement of respiratory rates during sleep, which the device uses to provide quality of sleep scores to its users. That study showed it to be among the most accurate measurement tools for respiratory rate short of invasive procedures, which is what has led researchers behind this new study to hypothesize that it could be valuable as a sort of early-warning system for detecting signs of abnormal respiratory behavior in COVID-19 patients before those symptoms are detectable by other means.

I'm still waiting for my Oura Ring (that is also participating in research like this) so will be watching the outcome of this wrist-worn research. I did comment last week that it's a pity Fitbit did not also build temperature and respiration detection into their new Charge 4 - the COVID-19 outbreak would have been the perfect stimulus for people to upgrade their Fitbits.

No group calling WebRTC based VC is end-to-end encrypted by default - for really secure VC rather self-host free Jitsi Meet

Date Published: Wed, 1 Apr 2020 14:48:44 +0200

Zoom has got very popular very quickly and yes a number of issues are arising highlighting potential privacy concerns. It is popular fore good reason: Works very well, has great features, and invitees don't need to register.

But it is built on WebRTC (as are many other video conferencing platforms now) which was designed for secure one-on-one (peer-to-peer) conferencing. So no-one can snoop on the traffic passing over the Internet but your client side app and the enterprise hosting the service instance for group calling potentially could.

To this end Zoom has been addressing the client issues (passing data back to Facebook), have amended their privacy policy making it more acceptable, and you can also set a number of default security options for meeting rooms. For example allowing telephone calls to bridge to your video chat does require the service to decode/encode to the phone otherwise that won't work, so disabling this option is probably good.

There are some services such at Riot Matrix and Cisco Webex that can optionally enable full E2EE but it usually either costs in terms of price, network ovberhead, or limited numbers which can group conference.

However, if your organisation is a government or needs to be more sure around the security it is probably best to self-host something like Jitsi which you can fully control (or at least control access to it). Your organisation is the "man in the middle".

See Zoom's end-to-end encryption isn't actually end-to-end at all. Good thing the PM isn't using it for Cabinet calls. Oh, for f... as well as an article about WebRTC and group calls at https://trueconf.com/webrtc.html and also https://wire.com/en/blog/is-your-video-conference-solution-secure/.
