Results of two studies may explain why some people develop diabetes after catching the virus
Covid-19 can infect insulin-producing cells in the pancreas and change their function, potentially explaining why some previously healthy people develop diabetes after catching the virus.
Doctors are increasingly concerned about the growing number of patients who have developed diabetes either while infected with coronavirus, or shortly after recovering from it.

On a recent afternoon, Steven Pinker, the cognitive psychologist and bestselling author of upbeat books about human progress, was sitting in his summer home on Cape Cod, thinking about Bill Gates. Pinker was gearing up to record a radio series on critical thinking for the BBC, and he wanted the world’s fourth richest man to join him for an episode on the climate emergency. “People tend to approach challenges in one of two ways – as problem-solving or as conflict,” Pinker, who appreciates the force of a tidy dichotomy, said. “You can think of it as Bill versus Greta. And I’m very much in Bill’s camp.”
A few weeks earlier, Gates had been photographed in Manhattan carrying a copy of Pinker’s soon to be published 12th book, Rationality, which inspired the BBC series. “We sent it to his people,” Pinker said. Pinker is an avid promoter of his own work, and for the past 25 years he has had a great deal to promote. Since the 1990s, he has written a string of popular books on language, the mind and human behaviour, but in the past decade, he has become best known for his counterintuitive take on the state of the world. In the shadow of the financial crisis, while other authors were writing books about how society was profoundly broken, Pinker took the opposite tack, arguing that things were, in fact, better than ever.

Researchers excavating a cave network on the Rock of Gibraltar have discovered a new chamber, sealed off from the world for at least 40,000 years, that could shed light on the culture and customs of the Neanderthals who occupied the area for a thousand centuries.
In 2012, experts began examining Vanguard Cave, part of the Gorham’s Cave complex, to determine its true dimensions and to see whether it contained passages and chambers that had been plugged by sand.

A 25m-year-old eagle fossil discovered on a remote outback cattle station in South Australia has been identified as one of the oldest raptor species in the world.
Palaeontologists discovered the eagle fossil on the shore of a dry lake known as Lake Pinpa in 2016, and have since identified it as a new species, Archaehierax sylvestris, in a study published in the journal Historical Biology.

Tributes have poured in for a doctor in Papua New Guinea’s Western Province who died last week, in the country’s first death of a healthcare worker from Covid-19 confirmed by the government.
Dr Naomi Kori Pomat, 60, the director for curative health services at the Western Provincial Health Authority (WPHA), was medevaced to Port Moresby after contracting the virus and died on 19 September.

Here is a round-up of all the top Covid stories from the UK and around the world so far today:
A decline in public services in the UK could be hidden behind a “Covid crisis smokescreen”, unions have warned.
It comes amid calls from union chiefs for rail and bus services to be renationalised to avert “disastrous” cuts to services and jobs and increases in fares.
People just will not travel on trains if fares go up, and coupled with the new ways of working, there is a real danger that the railways will be hollowed out.

It was out of desperation that Michael Raymond found himself sitting in a remote retreat in the Peruvian Andes, sipping a cup of bitter tea.
Raymond had reached breaking point. His 16-year career as an electrical engineer in high–security situations for the Australian air force had seen him deal with near-death experiences, crashes, casualties and “the aftermath of human remains”.

For centuries, shepherds from the small village of Aas in the French Pyrenees led their sheep and cattle up to mountain pastures for the summer months. To ease the solitude, they would communicate with each other or with the village below in a whistled form of the local Gascon dialect, transmitting and receiving information accurately over distances of up to 10 kilometres.
They “spoke” in simple phrases – “What’s the time?”, “Come and eat,”, “Bring the sheep home” – but each word and syllable was articulated as in speech. Outsiders often mistook the whistling for simple signalling (“I’m over here!”), and the irony, says linguist and bioacoustician Julien Meyer of Grenoble Alpes University in France, is that the world of academia only realised its oversight around the middle of the 20th century, just as the whistled language of Aas was dying on the lips of its last speakers.

For someone with a long history of depression and anxiety, plus a morbid fear of public speaking, taking up standup comedy might seem like a masochistic decision. Yet to me it makes perfect sense. Excruciating fear of failure is at the heart of most people’s aversion to attempting to make a room full of strangers laugh. But controlling that fear, and not succumbing to it, is the central reason I’ve chosen to expose myself in this very public and potentially humiliating way.
I grew up in comfortable, middle-class suburban Hertfordshire in the 1970s and 80s, but my upbringing was a complex one of emotional uncertainty. Years of therapy have lent me an understanding of how I learned to cope over the years. To avoid facing difficult issues during my childhood and teenage years I buried my emotions, and that evasion only escalated in adulthood. By my early 20s, I was mentally ill-equipped to deal with life’s thornier challenges.

A planned sixth day of protests in Melbourne was a flop but more are planned for tomorrow, AAP reports.
Police have snuffed out a sixth day of anti-lockdown and anti-vaccine protests in Melbourne, dispersing and arresting would-be demonstrators.
Hundreds of police lined St Kilda beach and arrested dozens of people on Saturday as protesters initially gathered at Luna Park.

For 40 years, Catherine Simpson thought she knew who she was: a nurse, a mother of three, a daughter and a sister. She looked like her mother, Sarah, but had the same temperament as her father, George: calm, unflustered, kind.
Then her father died. There was a dispute over his will, and that led her mother to call and tell her something that made the ground dissolve beneath her feet. George had had a vasectomy long before Catherine was born. She and her brother had been donor conceived in Harley Street using the sperm of two different anonymous men. George was not her biological father.

Mexico’s scientific community has reacted with outrage after the country’s chief prosecutor requested arrest warrants for 31 scientists, researchers and academics on accusations of organised crime, money laundering and embezzlement – charges that could land them alongside drug cartel kingpins in one of the country’s most notorious lockups.
A judge at the maximum security Altiplano prison – from which Joaquín “El Chapo” Guzmán escaped in 2015 – denied granting the arrest warrants on Wednesday. But the federal prosecutor immediately announced plans to pursue arrest warrants for the third time.

Some years ago, in Afghanistan, the anthropologist Scott Atran asked a Taliban fighter what it would take to stop the fighting, because families on both sides were crying. The fighter replied: “Leave our country and the crying will stop.”
The crying may not have stopped, but the Taliban have taken control of Afghanistan without an air force, heavy arms or expensive training, against US-backed Afghan government forces that outnumbered them four to one. In doing so, they have taken an important step closer to realising their stated goal, which is the creation of an Islamic emirate governed according to their interpretation of sharia law.

New scientific research conducted by archaeologists has uncovered what they believe are the oldest known human footprints in North America.
Research done at the White Sands national park in New Mexico discovered the ancient footprints, with researchers estimating that the tracks were between 21,000 and 23,000 years old, reported Science.

Fossil hunters have unearthed remnants of the oldest – and probably weirdest – ankylosaur known so far from a site in the Middle Atlas mountains in Morocco.
The remains of the heavily armoured animal are extraordinary in being the first to have defensive spikes that are fused to the skeleton, a feature researchers say is unprecedented in the animal kingdom.

Easter Island’s famous megaliths have relatives on islands thousands of miles to the north and west, and so did the people who created them, a study has found.
Over a 250-year period separate groups of people set out from tiny islands east of Tahiti to settle Easter Island, the Marquesas and Raivavae – archipelagos that are thousands of miles apart but all home to similar ancient statues.

A crucial series of Albert Einstein’s calculations, scrawled down as the physicist struggled to account for an anomaly in the orbit of Mercury while developing his theory of general relativity, is set to be auctioned for an eye-watering estimate of up to €3m.
Christie’s France and auction house Aguttes, who will auction the manuscript in Paris on 23 November for an estimate of €2m-€3m, said it documents a crucial stage in the development of the theory of general relativity, and is “without doubt the most valuable Einstein manuscript ever offered at auction”.

Thousands of women with ovarian cancer could benefit from a revolutionary drug combination after it was shown to shrink tumours in half of patients with an advanced form of the disease.
The pair of drugs – which work together to block the signals cancer cells need to grow – could offer a new treatment option for women with a type of ovarian cancer that rarely responds to chemotherapy or hormone therapy.
