Fresh air or foul odour? How Covid can distort the sense of smell

Coronavirus-induced parosmia is surprisingly common and the sensory confusion can have profound effects

Deirdre likens her body odour to raw onions; Deepak says his favourite aftershave smells foul, and coffee like cleaning products; Julie thinks coffee and chocolate both smell like burnt ashes.

Most people are aware that a cardinal symptom of Covid-19 is loss of smell, or anosmia. It may last for weeks or even months. Increasingly though, those who have recovered subsequently develop another disorienting symptom, parosmia, or a distorted sense of smell. This typically results in things that once smelled pleasant smelling bad or rotten.

Call for action on TB as deaths rise for first time in decade

Tuberculosis campaigners tell G20 leaders $1bn is needed annually for vaccine research to reverse decades of underfunding

A group of tuberculosis survivors are calling for more funding and action to find new vaccines, after the numbers dying of the infection rose for the first time in 10 years.

In 2020, 1.5 million were killed by TB and 10 million infected, according to the World Health Organization. Campaigners want world leaders to invest $1bn (£730m) every year into vaccine research, spurred on by the momentum from the Covid jab development.

‘I’m scared I’ve left it too late to have kids’: the men haunted by their biological clocks

It’s certainly not just women who worry about ageing and procreation – and now men have begun speaking about their own deep anxieties

It was when Connor woke up in the middle of the night to go to the bathroom that he started thinking about it. The 38-year-old civil servant from London got back into bed and couldn’t sleep: he was spiralling. “I thought: ‘Shit, I might not be able to have children. It actually might not happen,’” he says.

“It started with me thinking about how I’m looking to buy a house, and everything is happening too late in my life,” Connor says. “Then I started worrying about how long it would take me to save again to get married, after I buy the house. I was doing the maths on that – when will I be able to afford to be married, own a house and start having kids? Probably in my 40s. Then I started freaking out about what the quality of my sperm will be like by then. What if something’s wrong with the child? And then I thought, oh no, what if me and my girlfriend don’t work out? I’ll be in an even worse scenario in a few years.”

Why pregnant women need clearer messaging on Covid vaccine safety

Analysis: early uncertainty around vaccination advice for expectant mothers has left them confused and hesitant

In the early stages of the coronavirus pandemic, there was uncertainty around almost everything, from who was more adversely affected by Covid-19 to who should get vaccinated first – or at all.

But as awareness about the illness and vaccine safety has grown, one group in particular remains confused and torn about the risk of immunisation: expectant mothers.

Astronomers spot first possible exoplanet outside our galaxy

Saturn-sized planet candidate has been identified in Whirlpool Galaxy 28m light years away

A possible Saturn-sized planet identified in the distant Whirlpool Galaxy could be the first exoplanet to be detected outside the Milky Way.

The exoplanet candidate appears to be orbiting an X-ray binary – made up of a normal star and a collapsed star or black hole – with its distance from this binary roughly equivalent to the distance of Uranus from the sun.

The psychology of masks: why have so many people stopped covering their faces?

In England, masks are expected and recommended in crowded and enclosed spaces – but not legally required. Many have abandoned them altogether. What would convince everyone to put them back on?

Dave stopped wearing his face mask “the second I didn’t have to. I grudgingly wore it, because it was the right thing to do and because it was mandatory,” says the teacher from East Sussex. “But I felt, and still do, that the reason we were told to wear masks was to make scared people feel less scared.” He didn’t feel awkward abandoning his mask, he says, as “hardly anybody bothers”, but he will put one on when visiting the vet, pharmacist or doctor, because he knows they want him to. “I feel it’s the respectful thing to do, but it’s a bit of theatre.”

Every month since July, when the legal requirement to wear face masks – along with other restrictions – ended in England, the number of mask-wearers has dropped. In figures released by the Office for National Statistics (ONS) last week, 82% of adults reported they had worn a mask outside their home in the previous seven days – a drop from 86% the previous month. But that seems high to me. In my own highly unscientific survey of people coming out of a shopping centre in a south coast town centre last week, only around one in 25 were wearing a mask and overwhelmingly they tended to be older people – the most vulnerable social group. “When everyone else stopped, I stopped,” says Holly. Her friend Chantelle works in a supermarket and also hasn’t worn a mask since July. Does she mind customers not wearing masks? “Not really,” she says, “because I’m not wearing one. Doing an eight-hour shift in it was horrible.” Would they go back to wearing masks? “If we had to, then yeah, I would,” says Holly, but neither would by choice.

Why people believe Covid conspiracy theories: could folklore hold the answer?

Researchers use AI – and witchcraft folklore – to map the coronavirus conspiracy theories that have sprung up

Researchers have mapped the web of connections underpinning coronavirus conspiracy theories, opening a new way of understanding and challenging them.

Using Danish witchcraft folklore as a model, the researchers from UCLA and Berkeley analysed thousands of social media posts with an artificial intelligence tool and extracted the key people, things and relationships.

The world was woefully unprepared for a pandemic. Let’s be ready for the next one | Elhadj As Sy

The Global Preparedness Monitoring Board is calling for a coherent action plan to counter future health emergencies

Two years ago, three months before coronavirus erupted, the Global Preparedness Monitoring Board (GPMB) issued a warning to the international community that a pandemic was only a matter of time, and that the world was not prepared. Tragically, we were proved right.

After 20 months of Covid-19, with nearly five million directly attributed deaths and economic devastation, we say again that the world is not prepared. It has neither the capacity to end the current pandemic in the near future, nor to prevent the next one.

David Frost says EU close to breaching Brexit deal over science programme

Minister ‘quite concerned’ about delay to finalising UK’s participation in €80bn Horizon Europe scheme

A fresh Brexit row has been blown open with Brussels after David Frost accused the EU of being close to breaching the trade deal struck last Christmas.

He said the UK was “getting quite concerned” about Brussels delaying ratification of the UK’s participation in the €80bn (£67bn) Horizon Europe research programme, costing British scientists their place in pan-European research programmes.

The last great mystery of the mind: meet the people who have unusual – or non-existent – inner voices

Does your internal monologue play out on a television, in an attic, as a bickering Italian couple – or is it entirely, blissfully silent?

Claudia*, a sailor from Lichfield in her late 30s, is not Italian. She has never been to Italy. She has no Italian family or friends. And she has no idea why a belligerent Italian couple have taken over her inner voice, duking it out in Claudia’s brain while she sits back and listens.

“I have no idea where this has come from,” says Claudia, apologetically. “It’s probably offensive to Italians.” The couple are like the family in the Dolmio pasta sauce adverts: flamboyant, portly, prone to waving their hands and shouting. If Claudia has a big decision to make in her life, the Italians take over.

Covid live: more than 325,000 in England get boosters in one day as UK chancellor rejects calls for immediate ‘plan B’

Latest updates: NHS chief says Saturday was ‘biggest day yet for Covid booster jabs’ as Rishi Sunak says Covid numbers don’t suggest action needed today

China has given complete doses of Covid-19 vaccines to about 75.6% of its population as of 23 October, National Health Commission spokesperson Mi Feng said on Sunday.

Some 1.068 billion people have been inoculated with the required dosages, out of a population of 1.412 billion, Mi told a news briefing.

Mummy’s older than we thought: new find could rewrite history

Discovery of nobleman Khuwy shows that Egyptians were using advanced embalming methods 1,000 years before assumed date

The ancient Egyptians were carrying out sophisticated mummifications of their dead 1,000 years earlier than previously thought, according to new evidence which could lead to a rewriting of the history books.

The preserved body of a high-ranking nobleman called Khuwy, discovered in 2019, has been found to be far older than assumed and is, in fact, one of the oldest Egyptian mummies ever discovered. It has been dated to the Old Kingdom, proving that mummification techniques some 4,000 years ago were highly advanced.

Good vibrations: tapping in to ASMR

ASMR, the euphoric tingling certain sounds provoke, has created online superstars with millions of followers. Is it just a weird fad, or could it help people with anxiety and depression?

When I was five years old something strange happened. After a busy afternoon finger-painting and running around, we were gathered by our teacher on the classroom carpet to listen to a story. I can’t remember which book she read – only that she began to do so in a soft voice, pitched somewherejust above a whisper.

Suddenly, a euphoric, tingling sensation started at the crown of my head and then travelled down my neck and back in waves. The more she read, the stronger the feeling became. I glanced at my friends, expecting to see them in a similar state of rapture, but they weren’t. So I kept the feeling a secret and soon forgot all about it.

I knew that was going to happen… The truth about premonitions

Uncanny and creepy, premonitions that turn out to be authentic can feel profound. But is there science to explain them?

Around seven years ago, Garrett, was in a local Pizza Hut with his friends, having a day so ordinary that it is cumbersome to describe. He was 16 – or thereabouts – and had been told by teachers to go around nearby businesses and ask for gift vouchers that the school could use as prizes in a raffle. There were five other teenagers with Garrett, and they’d just finished speaking to the restaurant manager when suddenly, out of nowhere, Garrett’s his body was flooded with shock. He felt cold and clammy and had an “overwhelming sense that something had happened”. He desperately tried to stop himself crying in front of his peers.

“It was like I’d just been told something terrible,” the now 23-year-old from the southwest of England says (his name has been changed on his request). “I couldn’t tell you exactly what it was, but I just knew something had happened.” Garrett returned home and tried to distract himself from a feeling he describes as grief. The phone rang. His mum answered it. A few hours earlier – around the time Garrett was in the restaurant – his grandfather had died from a sudden heart attack while on a cruise.

Covid testing failures at UK lab ‘should have been flagged within days’

Senior scientists say problems at Immensa site show private firms should not be carrying out PCR tests

Health officials should have known about major failings at a private Covid testing lab within days of the problem arising, rather than taking weeks to shut down operations at the site, senior scientists say.

About 43,000 people, mostly in south-west England, are believed to have wrongly been told they did not have the virus by Immensa Health Clinic’s laboratory in Wolverhampton in a debacle described as one of the worst scandals in the UK’s Covid crisis.

How to retrain your frazzled brain and find your focus again

Are you finding it harder than ever to concentrate? Don’t panic: these simple exercises will help you get your attention back

Picture your day before you started to read this article. What did you do? In every single moment – getting out of bed, turning on a tap, flicking the kettle switch – your brain was blasted with information. Each second, the eyes will give the brain the equivalent of 10m bits (binary digits) of data. The ears will take in an orchestra of sound waves. Then there’s our thoughts: the average person, researchers estimate, will have more than 6,000 a day. To get anything done, we have to filter out most of this data. We have to focus.

Focusing has felt particularly tough during the pandemic. Books are left half-read; eyes wander away from Zoom calls; conversations stall. My inability to concentrate on anything – work, reading, cleaning, cooking – without being distracted over the past 18 months has felt, at times, farcical.

Countdown to ecstasy: how music is being used in healing psychedelic trips

Jon Hopkins timed his upcoming album to the length of a ketamine high, while apps are using AI music to tailor drug experiences. Welcome to a techno-chemical new frontier

Two hundred psychedelic enthusiasts have converged in Austin, Texas for a “ceremonial concert” on the autumn equinox. People sprawl on yoga mats around a circular stage as staffers pace the candlelit warehouse, jingling bells and spritzing essential oils. While psychedelic drugs are prohibited, some attenders seem in an altered state, lying on their backs and breathing heavily as rumbles of bass from Jon Hopkins’ upcoming album, Music for Psychedelic Therapy, shakes the hushed space.

This is the first time Hopkins – known for acclaimed solo electronic albums as well as production for Coldplay and Brian Eno – has played his new record in public, and the crowd is visibly moved. As recordings of spiritual guru Ram Dass’s teachings fill the room on the final song, the woman next to me begins silently weeping.

Natural habitats of 30 cities around the world at risk due to ‘coastal hardening’, study suggests

Researchers estimate 1m sq km of seascape globally has been modified by coastal structures which bring in invasive species and damage habitat

Artificial structures have replaced more than half of the coastline of 30 cities around the world, according to new research suggesting coastal infrastructure will have a significant ecological impact if not well managed.

“Coastal hardening” – replacing natural coastal habitats with seawalls, breakwalls, wharves and other structures – is “consistently extensive” across cities in North America, the UK, Australia and New Zealand, finds a study published on Friday.

Largest triceratops ever unearthed sold for €6.6m at Paris auction

US collector ‘falls in love’ with 8-metre-long dinosaur found in South Dakota and reassembled in Italy

An 8-metre-long dinosaur skeleton has sold at auction for €6.6m (about £5.5m), more than four times its expected value, to a private collector in the US said to have fallen in love with the largest triceratops ever unearthed.

The 66m-year-old skeleton, affectionately known as Big John, is 60% complete, and was unearthed in South Dakota, in the US, in 2014 and put together by specialists in Italy.

South Korea launches its first homemade space rocket

President hails ‘excellent’ test, as rocket gets high enough, but fails to put dummy payload into orbit

South Korea’s first domestically produced space rocket reached its desired altitude but failed to deliver a dummy payload into orbit in its first test launch.

The South Korean president, Moon Jae-in, still described the test as an “excellent accomplishment” that takes the country a step further in its pursuit of a space launch programme.
