Researchers rethink life in a cold climate after Antarctic find

Scientists surprised by marine organisms on boulder on sea floor beneath 900 metres of ice shelf

The accidental discovery of marine organisms on a boulder on the sea floor beneath 900 metres (3,000ft) of Antarctic ice shelf has led scientists to rethink the limits of life on Earth.

Researchers stumbled on the life-bearing rock after sinking a borehole through nearly a kilometre of the Filchner-Ronne ice shelf on the south-eastern Weddell Sea to obtain a sediment core from the seabed.

Bill Gates: ‘Carbon neutrality in a decade is a fairytale. Why peddle fantasies?’

After putting $100m into Covid research, the billionaire is taking on the climate crisis. And first he has some bones to pick with his fellow campaigners...

Bill Gates appears via video conference – Microsoft Teams, not Zoom, obviously – from his office in Seattle, a large space with floor-to-ceiling windows overlooking Lake Washington. It’s a gloomy day outside and Gates is, somewhat eccentrically, positioned a long way from the camera, behind a large, kidney-shaped desk; his communications manager sits off to one side. If one had to stage, for the purposes of symbolism, a tableau of a man for whom a distance of 3,000 miles between callers still constitutes too intimate a setting, it might be this. “As a way to start,” says Gates’ aide, “would it be helpful for Bill to make a couple of comments about why he wrote his new book?” It is helpful, and I’m not ungrateful, but this is not how interviews typically commence.

There is an urge towards deference, when speaking to Gates, which attends few other people of commensurate fame. Celebrity is one thing, but wealth – true, former-richest-man-in-the-world wealth – is something else entirely; one has a sense of being granted an audience with the Great Man, a fact made more surreal by his famously muted persona. The 65-year-old has the lofty, mildly longsuffering air of a man accustomed to being the smartest guy in the room, leavened by wry amusement and interrupted, on the evidence of past interviews, by the occasional peevish outburst – most memorably in 2014, when Jeremy Paxman questioned him about Microsoft’s alleged tax avoidance. (“I think that’s about as incorrect a characterisation of anything I’ve ever heard,” he said, practically squirming in his seat with annoyance.)

Our understanding of Covid and the vaccines is constantly evolving. That’s a good thing | Abby Bloom

There will continue to be plenty more data gaps because the Covid-19 strain simply behaves like all influenzas and mutates continuously

By the time you read this it will be out of date.

Why? Because every day we receive new data that causes us to rethink and rewrite our response to Covid-19, notably vaccine programs. This is good. I will explain.

Life savers: the amazing story of the Oxford/AstraZeneca Covid vaccine

A year ago, two scientists began work on the response to a new virus. Now, as their vaccine is being given to millions, they tell of their incredible 12 months

Exactly a year ago, Oxford University scientists launched a joint enterprise that is set to have a profound impact on the health of our planet. On 11 February, research teams led by Professor Andy Pollard and Professor Sarah Gilbert – both based at the Oxford Vaccine Centre – decided to combine their talents to develop and manufacture a vaccine that could protect people from the deadly new coronavirus that was beginning to spread across the world.

A year later that vaccine is being administered to millions across Britain and other nations and was last week given resounding backing by the World Health Organization. The head of the WHO’s department of immunisation, vaccines and biologicals, Professor Kate O’Brien, described the jab as “efficacious” and “an important vaccine for the world”.

How to Avoid a Climate Disaster by Bill Gates; The New Climate War by Michael E Mann – review

Two eminent voices on the climate crisis present clear strategies for tackling emissions, deniers and doomsayers

President Joe Biden has promised a new era of American leadership on global climate action, after four years of unscientific denial and misinformation under Donald Trump. Two important new books by prominent American authors, both written before the result of the presidential election was known, should help to capitalise on the new spirit of cautious optimism by laying out bold but well-argued plans for accelerating action against climate change.

How to Avoid a Climate Disaster: The Solutions We Have and the Breakthroughs We Need by Bill Gates presents a compelling explanation of how the world can stop global warming by reducing greenhouse gas emissions effectively to zero. Gates and his wife, Melinda, are well known for their foundation’s tremendous work on improving health and tackling disease around the world, particularly in poor countries. It is this concern for the most vulnerable people on the planet that has meant Gates has occasionally appeared equivocal about climate and energy policies that he thought could undermine the fight against poverty and illness. However, this book lays out forcefully his understanding that the impact of climate change poses a far bigger threat to lives and livelihoods in developing countries – it is thwarting efforts to raise living standards because poor people, in every country, are the most at risk from droughts, floods and heatwaves.

When you can’t quit a crush

Falling head over heels in love is one thing, but if it becomes all-consuming you may be in ‘limerance’

A few years ago I was at my university’s library, frantically refreshing a dating app. Under my crush’s photo there was a location setting that told me how far she was from me. “One mile away!” I felt a surge of adrenaline and my mind started racing.

I was a promoter for a gay nightclub in London’s Soho, which was where I met Lucy. I’d drop my flyers on purpose and she’d help me pick them up. We had been on a few dates and were making plans to meet again. Then we came across each other on a dating app – “Fancy seeing you here!” – and matched as a joke. Even though dating apps were probably unreliable in their geolocation abilities, suddenly I could gauge her distance from me.

How should we address Charles Darwin’s complicated legacy?

The Descent of Man, 150 years old this month, is a work of humanist brilliance – yet its errors, particularly on gender, now make for uncomfortable reading

“Light will be thrown on the origin of man and his history.” That sentence is the sole reference to human evolution in Charles Darwin’s masterwork On the Origin of Species, which in 1859 set down the theory that explains how life on Earth has evolved. Darwin had entirely excluded humans from his scheme. That tease comes in the final chapter, almost like a post-credit scene in a superhero movie, as if to simply say: “To be continued…”

The sequel did come, in the form of The Descent of Man, published in February 1871. All of Darwin’s canon is worth reading (though the one about worms and vegetable mould is perhaps a bit niche), but The Descent of Man is my favourite, because it is the one where he holds humans up to the light. Darwin was a great writer, and the prose is typically grand:

Coronavirus live: UK records a further 621 Covid deaths, as 14.6 million people receive first vaccine dose

Coronavirus R number falls below 1 in UK; Cuomo faces calls to resign amid allegations of hiding nursing home deaths; High-risk groups missed off UK’s vaccine priority list. Follow the latest updates live

The UK government has been accused of repeatedly ignoring concerns that the quarantine rules for incoming passengers will fail to halt the spread of new coronavirus variants in the country, unions revealed two days before the measures become law.

The GMB Union has said its members and airport staff had been telling the Home Office for the past fortnight that they were concerned that passengers from 33 designated high-risk countries were still being allowed to mix with other travellers and staff before entering hotel quarantine for 10 days at a cost of £1,750.

More than 800,00 people have died from coronavirus across Europe since the pandemic began in December 2019, according to an AFP tally Saturday based on official sources.

AFP reports:

As of Saturday, 1630 GMT, there were 800,361 deaths recorded in the 52 countries and territories that make up the continent - including Russia and Turkey - for 35,395,270 declared cases.

That puts the continent’s death toll ahead of Latin America and the Caribbean, which has 635,834 dead for 20,021,361 cases; of the United States and Canada’s 502,064 deaths for 28,312,719 cases; and Asia’s 247,730 deaths for 15,641,940 cases.

Wales is first UK nation to offer Covid jab to top four priority groups

Everyone in top four categories has been offered first vaccine dose, says first minister

Wales has become the first UK nation to have offered a Covid jab to everyone in the top four priority groups, the first minister, Mark Drakeford has announced.

Last month, Drakeford was forced to defend Wales’s vaccination programme after criticism of delays from opposition parties and doctors. But at a press conference on Friday, he said that 66 days after people in Wales first began getting the jab, the key target had been achieved.

Dramatic discovery links Stonehenge to its original site – in Wales

Find backs theory that bluestones first stood at Waun Mawn before being dragged 140 miles to Wiltshire

An ancient myth about Stonehenge, first recorded 900 years ago, tells of the wizard Merlin leading men to Ireland to capture a magical stone circle called the Giants’ Dance and rebuilding it in England as a memorial to the dead.

Geoffrey of Monmouth’s account had been dismissed, partly because he was wrong on other historical facts, although the bluestones of the monument came from a region of Wales that was considered Irish territory in his day.

Coronavirus live: France advises single vaccine dose for those who had Covid; Germany shut parts of land border

French health authority will give one jab to previously infected people; Germany to ban travel from Czech border regions and Austria’s Tyrol

Reuters reports:

The French government has no plans for now to order local lockdown measures in the eastern area of Moselle to rein in the spread of highly contagious Covid-19 variants, health minister Olivier Veran said on Friday.

Veran told reporters that a high number of cases of the South African Covid-19 variant had been found in the region.

The World Health Organizations’ director general, Tedros Adhanom Ghebreyesus, has discussed US support for COVAX vaccines:

I so appreciated today’s call with @CDCDirector Dr. Rochelle Walensky on our organizations' enduring partnership. It was good to discuss ‘s support for @ACTAccelerator and COVAX, #VaccinEquity, prioritizing robust public health systems, and our partnership to #EndPolio. pic.twitter.com/LVba0R3aFq

Pigs can be trained to use computer joysticks, say researchers

Study found pigs were able to move a cursor to hit a wall on a screen and earn a treat

They’ve long been thought of as smarter than your average animal, but now researchers claim they have taught pigs to use a joystick, suggesting they are even cleverer than previously thought.

Pigs have previously been found to be capable of a host of tasks, including solving multiple-choice puzzles, and learning commands such as “sit”.

Ursula von der Leyen admits failings in EU Covid vaccine rollout

European commission leader says bloc late to authorise jabs and ‘not where it wants to be’

The EU is “not where it wants to be” with its coronavirus immunisation programme, Ursula von der Leyen has conceded, as she faced MEPs in the European parliament amid mounting criticism of the bloc’s slow deployment of vaccines.

“We were late to authorise,” the European commission president said. “We were too optimistic when it came to massive production, and perhaps too confident that what we ordered would actually be delivered on time. We need to ask ourselves why that is the case.”

Astronomers’ hopes raised by glimpse of possible new planet

Bright speck in space near Alpha Centauri A may be evidence of asteroids or dust – or a technical glitch

Astronomers have glimpsed what may be a previously unknown planet circling one of the closest stars to Earth.

Researchers spotted the bright dot near Alpha Centauri A, one of a pair of stars that swing around each other so tightly they appear as one in the southern constellation of Centaurus. The stars form what is called a binary system 4.37 light years away, a mere stone’s throw in cosmic terms.

WHO investigation into Covid-19 origins offers no quick answers

Analysis: start of long process by Wuhan team junks Trump allies’ claim that coronavirus escaped from a laboratory

The press conference given by the World Health Organization’s investigative team in Wuhan is unlikely to silence the most conspiratorial of the conspiracy theorists who took their lead from the fever dreams of the former Trump administration.

Indeed, the first and very partial findings in what was always going to be a long and drawn-out process have not told us much we did not already know about the origins of the coronavirus pandemic.

How can Covid vaccines be tweaked to tackle new variants?

Drugmakers are looking at ways to improve their vaccines so they are ready for mutations of the virus

Emerging variants of the virus that causes Covid-19 have triggered concerns that the vaccines developed to date will not provide the high level of protection seen in clinical trials. Concerning variants have been identified in California, South Africa, Brazil and the UK.

But not every variant needs a new vaccine, since vaccines produce a broad immune response that will probably cover many mutations. Here’s what needs to be done to assess whether a vaccine needs to be tweaked, and how to tweak it.
