Herd immunity means that after a certain percentage of a population is immune to a disease, the whole population is. This is usually achieved through vaccination but some are not convinced.

A single-celled algae, barely visible to the eye, plankton contributes to some of the world's most important resources and is essential to the food chain that supports all life.

From a kidult superhero movie to a spooky period melodrama, these films will provide entertainment for all the family

Kidult superhero movies are nothing new, but this 2018 animated splinter off the Sony-Spidey combine does something really smart with the money-spinning multiverse concept. In Rodney Rothman, Bob Persichetti and Peter Ramsey’s version, Spider-Man is reborn across the dimensions – as Gwen, as a private eye, as a pig – and the result is a fruitfully mind-bending recalibration of the entire mythos.

Shriver’s contentious views on diversity thread through the story of a couple’s strained relationship with exercise

Lionel Shriver’s scabrously funny 15th novel presents a dyspeptic view of people in thrall to exercise. In 2013 Shriver’s own daily regime involved “130 press-ups, 200 side crunches, 500 sit-ups and 3,000 star jumps … The jumps take 32½ minutes, or three every two seconds”. The Motion Of The Body Through Space was written, she recently revealed, after she realised that she may be more dedicated to her exercise than to her writing.

The protagonist, Serenata Terpsichore (“rhymes with chicory”), is a 60-year-old woman from upstate New York with a beguiling voice and ruined knees. The former she puts to lucrative use as a voiceover artist and narrator of audiobooks. The latter are the result of a lifetime’s adherence to the doctrine of working out; in particular the belief that 10-mile runs are the key to longevity and good health.

First there was crowded Bondi, then the deserted beaches, cordoned off with police tape. If you look closely, a whole nation can be read on the sand

A country reveals itself in a crisis. Americans are buying a record number of guns, in the UK Boris Johnson was reluctant to implement a full lockdown because he baulked at the idea of closing the pubs. In Australia, it is our beaches that are the metaphorical hills that we are metaphorically dying on.

Yeah, we want to beat this virus, but we also want to get a swim in.

The chief prosecutor will seek capture of Jordan Goudreau as well as two US-based advisers to opposition leader Juan Guaidó

• How the plot to invade Venezuela fell apart

Venezuela’s chief prosecutor has ordered the arrest of a former Green Beret and two opposition figures living in the United States for their purported role in a botched operation aimed at removing Nicolás Maduro from power.

Tarek William Saab said Venezuela will seek the capture of Jordan Goudreau, a military veteran who has claimed responsibility for the attack, as well as Juan José Rendón and Sergio Vergara, two US-based advisers to the opposition leader Juan Guaidó.

Corporate watchdog’s move comes after a court earlier banned Mayfair 101 from advertising two other products

The corporate watchdog is looking into a new investment product issued by Mayfair 101, the group that has bought the cyclone-ravaged Dunk Island resort, after alleging in court that it had misled people by comparing its previous offerings to bank term deposits.

On Thursday, the Australian Securities and Investments Commission issued a general warning against advertisements that compare fixed-interest products to bank term deposits as part of a broader crackdown on potentially misleading marketing by investment groups.

Huge losses driven partly by fall in valuation of Australian pay TV service Foxtel and decline in news advertising revenue

Rupert Murdoch’s global media empire, News Corp, lost US$1bn in the three months to the end of March and is expecting more financial pain as the economic fallout from the coronavirus crisis continues.

The chief executive, Robert Thomson, said there was a fresh wave of cost-cutting ahead for the group, including a “strategic review of our Australian newspaper holdings” that could signal further job losses at the company’s smaller mastheads.

A New South Wales harbour master has told an inquiry he “did not understand” an email that told him to treat the Ruby Princess “as if it has a positive Covid-19 result” when it came into Sydney Harbour on 18 and 19 March.

Cameron Butchart, who was the duty harbour master on 18 March, said NSW Health’s assessment that the ship was “low risk” introduced “an unfortunate element” into his decision-making.

Allegations of identity theft involving 150 Australians have forced the government to pause the early release of superannuation, after police froze $120,000 believed to have been ripped off from retirement savings.

On Friday the assistant treasurer, Michael Sukkar, announced the Australian Tax Office would pause requests for early access of superannuation until Monday “out of an abundance of caution” to consider further anti-fraud protection.

A 16-year-old Aboriginal boy was forced to remove his shorts and squat during a search, but disciplinary action has not been recommended

A New South Wales police watchdog investigation into seven strip searches including one in which a 16-year-old Aboriginal boy was physically forced to remove his shorts and squat has found that all of them were unlawful.

But the watchdog has been criticised for “not going far enough” in its findings, with Sarah Crellin, a principal solicitor at the Aboriginal Legal Service, saying she was “deeply disappointed that there have been no recommendations for disciplinary action” against individual officers.

Exclusive: Documents show department has stopped recommending assessment of ‘key threatening processes’ affecting native wildlife

The federal government has stopped listing major threats to species under national environment laws, and plans to address listed threats are often years out of date or have not been done at all.

Environment department documents released under freedom of information laws show the government has stopped assessing what are known as “key threatening processes”, which are major threats to the survival of native wildlife.

Queen guitarist says ‘I won’t be able to walk for a while’ after injury during lockdown and lambasts Boris Johnson over coronavirus

Brian May has complained of “relentless pain” after he was taken to hospital following a gardening injury that tore muscles in his buttocks – and, while in recovery, made a sustained attack on Boris Johnson’s preparedness for coronavirus.

Writing on Instagram, the Queen guitarist said: “I managed to rip my gluteus maximus to shreds in a moment of overenthusiastic gardening. So suddenly I find myself in a hospital getting scanned to find out exactly how much I’ve actually damaged myself. Turns out I did a thorough job – this is a couple of days ago – and I won’t be able to walk for a while … or sleep, without a lot of assistance, because the pain is relentless.”

The comic essayist on crying over Olive Kitteridge, his love for Richard Yates and the books that make him laugh

The book I am currently reading
Hidden Valley Road. It’s a nonfiction book about a family with 12 children, half of whom turn out to be schizophrenic. In the opening pages the mother sews a live bird’s eyes shut. And she’s one of the few who isn’t mentally ill!

The book that changed my life
Kurt Vonnegut’s Breakfast of Champions. A friend read it out aloud to me when we were hitchhiking across America in 1976, and it made me think: “That’s right – books!” After high school I had forgotten about them. As soon as I got a stable address, I secured a library card, and started making up for lost time.

Those less convinced in Australia cast doubt on source of Wuhan lab ‘intelligence’. Plus: Trump and Jennifer Hawkins

The origin of the coronavirus has opened up a new battlefield between the Murdoch press and just about everyone else – and given the Daily Telegraph’s Sharri Markson an international platform on Rupert Murdoch’s Fox News.

Following in the footsteps of her colleague Miranda Devine, who also made it onto Fox News, Markson told Tucker Carlson Tonight the “bombshell dossier” she had uncovered showed some of the world’s foremost intelligence agencies were investigating whether the virus was linked to a lab in Wuhan.

A Derek Underwood-inspired England – assisted by the Oval’s resourceful spectators – beat the final-day flood, clock and Australian resistance to start my lifelong obsession with cricket

I was clearing out some old papers a while back when a small pink slip fell out. Even after 50 years I knew instantly what it was because it had been stuck to my bedroom wall when I was a teenager: indeed the old brown shadows of the tape were still there. It was the ticket for my first day’s Test cricket: the fifth Test against Australia at the Oval on 22 August 1968: Derek Underwood’s match and the game that started a lifelong obsession.

We joined my friend Matthew and his mother – two teenagers, what were we thinking of, taking our mothers? – and caught an early train from deepest Berkshire. London was a big, strange place where we rarely ventured and never as far south as SE11. We were square to the wicket and the players were so distant as to be indistinct, almost lost against the crowd.

• ‘F1 can be pioneer’ for other sports to follow, says GPDA chief

The Grand Prix Drivers’ Association is confident the precautions being taken by Formula One mean the sport stands every chance of resuming as planned in Austria on 5 July.

Alex Wurz, chairman of the GPDA, will reassure his members that Formula One has put the safety of everyone involved at the forefront of its plans to return to racing after attending a meeting with F1 and the FIA on Friday.

From hosting the remainder of the Premier League season in Perth to the UFC Fight Island concept, ideas have ranged from bold to crazy

“When you’re going through hell, keep going.” Winston Churchill might not have had the coronavirus pandemic in mind when trotting out that particular gem, but trust him to find the right words almost a century before the fact. The Churchillian equivalent of “keep calm and carry on” is a mantra embraced by much of society right now, and sport is no different.

While health remains the primary concern in all walks of life, sporting bodies the world over have found themselves engaged in sessions of radical thinking to stave off looming economic ruin. In what predicament other than a global crisis could the term “NRL Island” be anything other than a genius concept for reality television?

The Australian government has launched Covidsafe, an app that traces every person running the app who has been in contact with someone else using the app who has tested positive for coronavirus in the previous few weeks, in a bid to automate coronavirus contact tracing, and allow the easing of restrictions.

Here’s what we know about the app so far.

Some people have found returning to the family home a blessing, but for others it has been anything but smooth sailing

Covid-19 has reshaped geographic boundaries. It has left many financially distressed. Expatriates have returned from overseas for indefinite periods of time, and vulnerable people require more help than usual. For all these reasons, and many more, adult children have found themselves doing something that might previously have been unthinkable: moving back in with their parents.

Some are finding the experience transformative. One woman, who left New York for her parent’s rural home, told me that the space and country air have made her reconsider whether she will ever return to the city. But there are also downsides. “I’m craving male attention more than I ever have before,” she confessed. When flirting over apps stopped cutting it, she wound up ordering a vibrator in an unmarked box, and fended off her younger siblings in order to retrieve it from the mailbox.

They’ve faced drought, extreme heat and bushfires, and now they have to deal with a new paranoia courtesy of the pandemic

Australia’s bats are turning up in increasing numbers in city suburbs. But as they search for food, they’re bringing for some a newfound paranoia thanks to a global pandemic that likely sprang from one of their overseas relatives.

In Ingham in far north Queensland, an influx of more than 200,000 little red flying foxes in January was variously described as a “swarm”, a “tornado” and an “infestation”.
