A U of S researcher says there is no evidence that COVID-19 jumped to humans from bats.

Alberta's use of a smartphone app to help slow the spread of the coronavirus may provide other provinces with insight on what to do — and what to avoid — as Canada begins easing restrictions, heightening the need for effective contact tracing.

WeChat is one of the world’s most popular apps, but researchers at the University of Toronto caution it is surveilling international users and using their information to broaden censorship on the app in China.

Health experts agree contact tracing is a key measure to contain a pandemic. But is the answer a contact tracing app?

Sidewalk Labs, a Google-affiliated company, is abandoning its plan to build a high-tech neighbourhood on Toronto’s waterfront, citing what it calls unprecedented economic uncertainty.

As New Brunswick and other provincial governments contemplate launching COVID-19 contact-tracing apps, privacy watchdogs from across the country have issued joint guidelines on what they are describing as an "extraordinary" measure, urging transparency and accountability.

In this week's issue of our environment newsletter, we look at the sustainability of different types of face masks and how orphan oil and gas wells in Alberta could be converted into green energy projects.

As a pioneering female DJ duo, the two best friends were integral to the rise of the 90s dance scene, before a car accident changed everything. Storm talks about the soul sister she lost

Storm remembers the sound of glass shattering, but not how many seconds or minutes had passed before she realised something awful had happened. A 4.5kg metal cat’s eye had been dislodged from the road ahead by a passing van, and had smashed through their car windshield on the passenger side. It left Kemistry – her best friend and partner in one of the UK’s most pioneering drum’n’bass outfits – with devastating injuries. Minutes later, she died.

“I’ve had some really dark times and really dark thoughts,” says Storm, 20 years on from the accident. “Thoughts about me not being here, about going to join her.”

Will Toledo’s alt-rockers have emerged out of lo-fi fuzz, but seem unsure of where to turn as they drift toward the mainstream

Anyone wondering how things have changed in the world of lauded US alt-rockers Car Seat Headrest might consider the four years that separate Making a Door Less Open from their last album of new material. Ordinarily there would be nothing unusual about that gap – but in the first four years of Car Seat Headrest’s existence, its mastermind, Will Toledo, released seven albums (one of them a two-hour double), four EPs (one of them as long as an album) and two compilations of outtakes. That’s more than 150 songs and 12 hours of music: a lo-fi spewing forth of ideas that won Toledo a cult following, which then grew exponentially, both in size and rabidity, when he recruited a band and signed to the august US indie label Matador.

Raised in Sheffield, Heaton, 57, founded the Housemartins in the early eighties. They had hit singles with Happy Hour and Caravan Of Love before splitting in 1988. Heaton then formed the Beautiful South, releasing 10 albums before disbanding in 2007. With former band member Jacqui Abbott, Heaton has released three albums, the most recent being Manchester Calling. He is married with three children and lives in Manchester.

• The best arts and entertainment during self-isolation

Isolation has definitely been a test, but I’m really lucky: I’m able to work on new music while quarantined with my best friends in Toluca Lake, Los Angeles. I’ve been super active on Twitter and Instagram, and playing Animal Crossing and Mario Kart with my fans after sharing my Nintendo Switch codes online – it’s really important for me to check in on my fans as I worry about them a lot. They have truly kept me sane, so I’m keeping an eye open for anybody that needs to talk.

During a 1990 Senate race in his home state of North Carolina, Jordan refused to endorse Democrat Harvey Gantt, an African American who was running against the incumbent Republican Jesse Helms, a notorious racist. Jordan, who at the time had already won the first of his five NBA MVP awards, explained away his refusal to take a stance by saying “Republicans buy sneakers, too”.

• Quarterback left New England for Tampa Bay in March
• Covid-19 means practices with teammates are missing

Eli Manning, the man who beat Tom Brady in two Super Bowls, thinks his old rival may find it tough adapting to life with his new team, the Tampa Bay Buccaneers.

Brady left the New England Patriots in March after two decades and six Super Bowl titles with the team. The Buccaneers are blessed with weapons, such as Mike Evans, Chris Godwin and Brady’s old teammate Rob Gronkowski on offense, but the Covid-19 lockdown is an added obstacle for the quarterback as he adjusts to a new playbook.

Colin O’Brady took on the elements, a relentless rival and weeks of isolation as he walked solo and unassisted across the southernmost continent

Having trekked hundreds of miles into Antarctica in late 2018, American Colin O’Brady reached a memorable landmark: the south pole. It was only a waypoint on the way to O’Brady’s pursuit of a record – the first-ever unaided, unsupported solo crossing of the continent. Yet when he made it to “due south”, it was time for an impromptu celebration. He did a handstand, posing as if he was holding up Earth.

“I was at the south pole, the bottom of the world,” O’Brady tells the Guardian. “It was a moment of riding high. My emotions were on top of me … I’m thankful I let myself experience that positive moment.”
