Your wearable media, whether it’s an Apple Watch, Fitbit, or other fitness tracker, can offer a COVID-19 early detection system based on heart rate variability (HRV). In a study on Mount Sinai, researchers followed a group of 297 health workers for about half a year and noted changes in heart rhythm that could indicate that someone had a coronavirus for a week before feeling unwell. This would be especially helpful for asymptomatic people who may spread the virus and not show up or feel sick.
A similar study by Stanford University of participants wearing trackers from Garmin, Fitbit, Apple and others found that 81% of patients tested positive for COVID-19 also saw changes in resting heart rate up to nine and a half days before to show symptoms. Some companies are even planning special wearable devices for clinical conditions to help treat and monitor COVID-19.
The IEA says emissions in the sector should fall by more than 70% by 2030.
The COVID-19 pandemic has slowed the industry enough to create a small reduction in methane emissions, according to a report by the International Energy Agency (IEA). The organization mainly attributes the approximately 10% drop in emissions from oil and gas companies to lower production amid reduced demand. However, he said these operations still released more than 70 million tonnes (77 million tonnes) of methane into the atmosphere in 2020.
Agriculture remains the largest source of human methane emissions (about a quarter), followed by energy. According to the IEA, leaks from the natural gas value chain cause about 60% of emissions in the industry. The agency wants to eliminate these leaks, which suggests that many of them can be removed at no net cost after the sale of the retained methane. Keep reading.

One week after losing access to Amazon’s hosting servers, Parler’s website is back online, at least in limited form. For now, it is hosting a statement from CEO John Matze, which says: “We will solve any challenge before us and plan to welcome you all soon.”
According to CNN, Parler’s domain is currently registered with a DNS provider known for offering safe havens in the past to websites such as 8chan and The Daily Stormer. Getting a website online is just one of the challenges Parler needs to address: Without access to the App Store and Google Play, Parler users will not have an easy way to install the software on their phones.

It is lighter and more suitable for modern music production.
Last year, Korg announced a remake of the limited-edition ARP 2600. Perhaps the most iconic synthesizer out there, it weighed about 68 pounds and would essentially want its own table or desk. So Korg did his best to shrink the 2600 down, resulting in the ARP 2600 M. That’s about half the size and tilts the scales at just 13 pounds, although he rejects the keyboard to help lose weight.
This is not a 100% true recreation of the modular synthesizer of the 70’s, but Korg has expanded the range of features to work better in a modern music environment. It also has USB host capabilities, so you can connect any USB MIDI controller if you need the keyboard back. Keep reading.
The discovery of the gravitational wave can help us understand space.
Scientists may have identified the gravitational waves that make up some of the background of the universe, not just those coming from unusual events such as collisions with black holes. The NANOGrav research team found a “strong signal” that could represent the background of the gravitational wave. These are waves of supermassive mergers of black holes in space.
This is not yet a definitive result, but further research can help determine the sources of these waves and perhaps how these “hidden” forces shape the universe. Keep reading.
