Researchers exploring Antarctica’s seabed have discovered a thriving, unprecedented colony of icefish 'about a third of the size of London'. 'We expected to see the normal Antarctic seafloor … [but] during the first four hours of our dive, we saw nothing but fish nests,' said Autun Purser, of the Alfred Wegener Institute for Polar and Marine Research in Germany, and lead author of the study published in Current Biology.
We mustn’t punish those who are fearful of getting the Covid vaccine, writes the mother of an autistic man who suffers from crippling anxietyI was disappointed by Dave Green’s letter (12 January) regarding the penalties he suggests for those who are unvaccinated. I can empathise with his words as a previous cancer patient myself, and also as a frontline nurse, but I disagree with his judgment on “anti-vaxxers”. Those who have chosen not to have the vaccine do not all share the same mindset, and it is worth bearing this in mind before they are all excommunicated from society.My adult son is autistic and is unvaccinated by choice. His belief system may differ from most people’s, but as he is housebound due to crippling anxiety, hopefully he will not be much of a risk to himself or others. Let’s be civilised enough not to alienate him further. Of course, he might have chosen to forgo the Covid vaccine without the complexities of an autism diagnosis, but we cannot punish those who are fearful or those who wish to preserve their self-determination.

Researchers make unprecedented discovery of 60m active nests while collecting data in Weddell SeaResearchers exploring Antarctica’s seabed have discovered a thriving, unprecedented colony of icefish “about a third of the size of London”.The surprise discovery of about 60 million active nests was made by a team of biologists while collecting routine data at 1.5-2.5 metres above the seafloor of Antarctica’s southern Weddell Sea. Before this discovery, the largest found colony contained only 60 nests. Continue reading...
Many people are at their peak of infectiousness at the very time that Sajid Javid has said they can now mix freely in societyThere have been many changes to isolation rules in England but the science of how Covid-19 spreads has remained the same. During the first waves of the pandemic, people were required to isolate for 10 days after testing positive. This was subsequently changed to seven days, so long as the person had a negative lateral flow test on days six and seven. Although data is still being collected on the impact of this change, the isolation period has been cut again: today, the health secretary, Sajid Javid, announced that people with Covid will only need to isolate for five days, so long as they show two negative lateral flow tests by day six.I’m deeply concerned about this. There is little scientific evidence to justify these reduced measures. Yes, some would argue that Omicron is mild compared to other variants, and does not result in massive hospitalisations. But a comprehensive review of research into 5,340 infected people around the world showed that the times at which these people were shedding the most virus, and were therefore most infectious to others, was between days three to six. The amount of virus each person shedded tailed off at days seven to nine. By day 10, no viable virus could be recovered from their respiratory tracts.Sally Cutler is professor in medical microbiology at the University of East London Continue reading...

Preservation of figure carved from single piece of wood is incredible, say archaeologistsAn extremely rare, carved wooden figure from the early Roman era has been unearthed in a waterlogged ditch in Buckinghamshire, the latest extraordinary find in the UK’s biggest ever archaeological dig along the 150-mile HS2 rail route.The 67cm-tall figure is carved from a single piece of wood. Archaeologists said its preservation was “incredible” given its age and material, but the lack of oxygen in the ditch helped prevent rotting over many centuries. Continue reading...
The surge has led to passengers stranded on ships, staff shortages and tour cancelations in addition to ports turning ships awayA surge in Covid infections on cruise ships is causing mayhem across the industry, leaving passengers stranded aboard ships, exacerbating staff shortages and prompting the CDC to warn US passengers against all cruise travel.The CDC director said this week that Covid cases have increased 30-fold in just two weeks. Every one of the nearly 100 cruise ships currently carrying passengers in US waters has reported enough Covid-19 cases to merit investigation by the CDC, according to the agency’s website.

Last week, the tech CEO Elizabeth Holmes – once described as ‘the next Steve Jobs’ – was convicted of fraud, and could face decades in prison. Her now collapsed company, Theranos, promised to revolutionise medicine with a machine that could run hundreds of health tests on just a pinprick of blood. Those claims have since been exposed as false – but could they ever have been true?Madeleine Finlay speaks to the Guardian’s wealth correspondent, Rupert Neate, about Silicon Valley’s trial of the century, and pathologist Dr Benjamin Mazer about why Theranos’s vision seemed impossible from the startArchive: ABC News, TedMed, CBS Mornings, NBC News, CNBC Continue reading...
The revolutionary new scope could provide a glimpse of the cosmos dating back billions of years, but first some painstaking adjustments are neededNasa has embarked on the months-long, painstaking process of bringing its newly launched James Webb space telescope into focus, a task due for completion in time for the revolutionary eye in the sky to begin peering into the cosmos by early summer.Mission control engineers at Nasa’s Goddard space flight centre in Greenbelt, Maryland, began by sending their initial commands to tiny motors called actuators that slowly position and fine-tune the telescope’s principal mirror.

Study confirms anecdotal evidence that lockdowns protected children against non-Covid illnessesHospital admissions for common childhood infections in England dropped by as much as 94% during the first year of the Covid-19 pandemic, according to the first major study of its kind.Doctors have previously reported anecdotally how Covid measures such as lockdowns inadvertently led to children being better protected against other illnesses.

Writers from Julian Barnes to Oliver Sacks and Petina Gappah find some profound truths in what gets lost to memoryI have always been fascinated by the human memory – its capacity, its acuity, its connections to emotions and our basic senses. Somehow the blob of gray gunk in my skull manages to recall everything from the statute of frauds I memorised in law school to the lyrics of pretty much any new wave single released in the 1980s. It’s the reason one whiff of Ralph Lauren Polo cologne takes me right back to a gropey nightmare in the cab of a pickup truck with the high school quarterback.But despite memory’s remarkable breadth and depth, we also know that it is fallible. Fragile. Even manipulable. Cognitive research has proved, for example, that eyewitness memory is far more confident and far less accurate than we instinctively believe. If we can’t believe our own memories, how can we trust ourselves? Memory is also reversible, and what we have forgotten is often as telling as what we recall. Continue reading...
The medical community must find answers for those suffering from long Covid. They are running out of time and hopeMy wife, Heidi, took her own life after a 13-month battle with long Covid that started as a mostly asymptomatic coronavirus infection. Long Covid took her from one of the healthiest, most vibrant people I’ve ever known to a person so debilitated that she could not bear another day on this planet.I came home one day last May to find that she’d decided to end her pain. As our 13-year-old son waited outside for the paramedics, I tried desperately to revive her. I did a good enough job that by the time we got her to the hospital they could restart her heart, but she was brain dead on arrival. The emergency room doctor assumed that she died from depression. When I told him, “She wasn’t depressed, it was long Covid,” he looked at me with bewilderment and asked, “What’s long Covid?” Continue reading...
Scientists and politicians have focused on the short-term impact of the virus – but we can no longer leave chronic patients to struggleDespite apprehension about high Covid-19 rates, my family Christmas in Yorkshire was wonderful. Unfortunately, the week after was marred by headache, fever and malaise. And a PCR test confirmed the worst – I had Covid-19 for the second time. My second encounter has been dominated by severe fatigue and reduced concentration, which though improving, have not yet resolved more than two weeks later. Worryingly, what I know about long Covid suggests that this could persist for several months – or longer.The World Health Organization defines long Covid as ongoing symptoms “three months from the onset of Covid-19”. In December, the Office for National Statistics (ONS) estimated that more than 1.3 million people in the UK had symptoms for four weeks or more after Covid-19, of whom 892,000 people (70%) had symptoms that persisted for at least 12 weeks, and 506,000 (40%) for at least one year. Dr Melissa Heightman, who leads the University College London hospital specialist long Covid clinic says that breathlessness, fatigue, cough, myalgia, chest pain, headache, “brain fog” and palpitations are most commonly reported. But many other symptoms may be present.Amitava Banerjee is professor of clinical data science and honorary consultant cardiologist at University College London and is leading the Stimulate-ICP study to investigate long Covid Continue reading...
Waitrose stocks Sunions, developed by decades of cross-breeding less pungent strains of onionChopping onions is a recurring kitchen nightmare that often reduces home cooks to tears, but red eyes could be a thing of the past as “tearless” onions go on sale in the UK for the first time.Next week Waitrose will start selling Sunions in its stores, a “brown, tearless and sweet” onion variety that is being billed as a “gamechanger” for red-eyed chefs. The onions, which are being marketed using the strapline “not a single tear”, have taken more than 30 years to perfect. Continue reading...
Analysis: As doctors monitor world’s first human recipient of pig heart, safety and ethical concerns remainThe world’s first transplant of a genetically altered pig heart into an ailing human is a landmark for medical science, but the operation, and the approach more broadly, raise substantial safety and ethical concerns.Surgeons at the University of Maryland Medical Center spent eight hours on Friday evening transplanting the heart from the pig into 57-year-old David Bennett, who had been in hospital for more than a month with terminal heart failure.

Last year the oceans absorbed heat equivalent to seven Hiroshima atomic bombs detonating each second, 24 hours a day, 365 days a yearI was fortunate to play a small part in a new study, just published in the journal Advances in Atmospheric Sciences, which shows that the Earth broke yet another heat record last year. Twenty-three scientists from around the world teamed up to analyze thousands of temperature measurements taken throughout the world’s oceans. The measurements, taken at least 2,000 meters (about 6,500ft) deep and spread across the globe, paint a clear picture: the Earth is warming, humans are the culprit, and the warming will continue indefinitely until we collectively take action to reduce greenhouse gas emissions.We used measurements from the oceans because they are absorbing the vast majority of the heat associated with global warming. In fact, more than 90% of global warming heat ends up in the oceans. I like to say that “global warming is really ocean warming”. If you want to know how fast climate change is happening, the answer is in the oceans. Continue reading...
The pandemic has left our best-laid plans in disarray, but we can still have spur-of-the-moment adventuresBack in the wild old days, my best buddy and I used to call going out “looking for trouble”. We weren’t hoping for a punch-up or a little light robbery, but a spontaneous adventure involving music, strangers or just the city at night. All that spur-of-the-moment fun has taken quite a beating since the pandemic began, for many millions of us. First came the lockdowns, social distancing and closed venues, then the cautious reopening when even a trip to the pub or an art gallery had to be booked weeks in advance. And now, just when it seemed the world was finally getting back to normal, Omicron has come wielding its everything’s-off-again sledgehammer, crushing all those dreams of nights out, holidays and raucous parties. Not only does it seem foolish to plan anything, but after two years of frustration and self-restraint, it’s hard to summon up the enthusiasm to do anything off the cuff.And that’s quite a loss. While we often think anticipation is half the fun, in 2016 researchers from two US universities found that people enjoyed activities more when they were impromptu. Scheduling a coffee break or a movie, for instance, made them feel “less free-flowing and more work-like”, wrote the authors. As Jane Austen put it 200 years ago in Emma: “Why not seize the pleasure at once? – How often is happiness destroyed by preparation, foolish preparation!” Continue reading...

It’s been called the most important glacier in the world. The Thwaites glacier in Antarctica is the size of Florida, and contains enough water to raise sea levels by over half a metre. Over the past 30 years it has been melting at an increasing pace, and currently contributes 4% of annual global sea level rise. Ian Sample speaks to marine geophysicist Dr Rob Larter about a new research mission to the Thwaites glacier, the role of Boaty McBoatface and what it’s like to see a region melt away before your eyes Continue reading...

The solution to today’s puzzleEarlier today I set you the puzzle below, which is based on Gödel’s incompleteness theorem. As I discussed in the original post, this theorem is one of the most famous in maths and states that in any mathematical system there will always be true statements that cannot be proved.For example, in a formal mathematical setting, the statement ‘This sentence is unprovable” is both true and formally unprovable. When Gödel published his theorem in 1931 it up-ended the study of the foundations of mathematics and its consequences are still being felt today. Continue reading...
Dominic Cummings | Science | Prayers | MarmaladeThe Conservatives warned that if Jeremy Corbyn were elected prime minister he would take Britain back to the 1980s. With all the cheese and wine parties at Downing Street (Dominic Cummings makes new claim of party in No 10 garden in lockdown, 7 January), it seems as if Johnson is aiming for the 1970s.
Contrary to mythical depictions of the iconic steeds as towering beasts, most in England were less than 14.2 hands highIn films and literature they are usually depicted as hulking, foot-stomping, snorting beasts but a new study has claimed that the medieval warhorse was typically a much slighter, daintier animal.A team of archaeologists and historians searching for the truth about the steeds that carried knights into battle has concluded that most were probably only the size of a modern-day pony.

Access to vaccines, masks and tests will help us make the awkward transition from pandemic to endemicIn May 2020, we and other scientists predicted that many regions of the world might never reach the herd immunity threshold for Covid-19 – the point at which enough people are immune to infection that transmission begins to slow down.This remains true today, even as vaccines have become accessible in wealthy nations and many people have built up immunity through vaccinations, boosters and previous infections.Erin Mordecai is an associate professor of biology at Stanford University. Mallory Harris is a PhD candidate at Stanford University, where she studies infectious disease Continue reading...
The proof that rocked mathsIn 1931, the Austrian logician Kurt Gödel published his incompleteness theorem, a result widely considered one of the greatest intellectual achievements of modern times.The theorem states that in any reasonable mathematical system there will always be true statements that cannot be proved. The result was a huge shock to the mathematical community, where the prevailing view was an unshakeable optimism about the power and reach of their subject. It had been assumed that maths was “complete”, meaning that all mathematical statements are either provable or refutable. The 25-year-old Gödel demonstrated this was incorrect by constructing a true statement that was not provable. Maths, he announced, has its limits. Continue reading...

My life is a constant struggle against the primitive part of my brain – and the forces designed to exploit itI experience frequent, urgent cravings for very specific things and act on them immediately. As soon as I open my eyes I often know exactly what I want: to wear a particular little outfit, buy a sandwich of a certain heft and filling from this shop in this postcode, eat it (for instance) on a bench under a tree. It’s a shame that the place in me capable of conjuring these whims also regularly churns out other, much more boring urges, and occasionally dangerous ones too. My brain is a constant game of Hungry Hungry Hippos, my dopamine receptors snapping noisily at an alarming rate, urging me to do things that actually bring me very little pleasure at all. Why do I want things that don’t make me feel good? I’m at the mercy of my lizard brain and the mechanisms of society designed to exploit it.The concept of the three-tiered brain – a primitive reptilian brain nestled like a living fossil in the clay of our most recently evolved, superior brains, was proposed in the 1960s by the neuroscientist Paul MacLean. Its scientific credulity holds about as much significance to me as that of the astrology app that sends me notifications each morning – it just provides a structure for me to think about my habits and how to change them. In short, the reptilian brain is the most primitive part of the brain. I visualise it quite literally as the lizard-like baby from Eraserhead, mewling and requiring constant attention from the other parts of the brain, the parts that have evolved over 10m years to quieten its cries.Eli Goldstone is the author of Strange Heart Beating Continue reading...

New DNA research by London-based scientists hopes to find cure for rapidly spreading conditionsMore and more people around the world are suffering because their immune systems can no longer tell the difference between healthy cells and invading micro-organisms. Disease defences that once protected them are instead attacking their tissue and organs.Major international research efforts are being made to fight this trend – including an initiative at London’s Francis Crick Institute, where two world experts, James Lee and Carola Vinuesa, have set up separate research groups to help pinpoint the precise causes of autoimmune disease, as these conditions are known.

Amid a hectic life, meditation can help make you happier and healthierJillian Lavender, a much-sought-after meditation teacher and author of a new book Why Meditate?, is on a mission to eliminate stress from people’s lives – not to manage it, or cope with, but to get rid of it. Altogether.“People talk about stress as something we have to learn to live with, particularly anxiety,” she says. “Actually we can do something about stress.” She believes we need to change our mindset around what she sees as one of the greatest causes of suffering today. There is no such thing as “good stress”, she says. “People are tired, exhausted and stressed. And they compensate for that by all sorts of behaviours and habits. I want to bring us into a normal state, a balanced state that is healthy.” Continue reading...
