‘Chance discovery’ near the temple of Zeus was probably used as votive offering, Greek ministry saysRain has helped uncover a small bull idol at ancient Olympia in what the Greek culture ministry said on Friday was a “chance discovery”.It said the bronze idol, found intact, was spotted by an archaeologist at the sprawling ancient site that inspired the modern Olympic Games during a scheduled visit by ministry officials.

Anxiety, boredom, claustrophobic relationships... characters from Jane Eyre to Mrs Dalloway can provide vital insights into how to live in these anxious times, writes Josh CohenShould we be suspicious of the idea that fiction can help us to live meaningful lives? After all, as Plato observed (via a fictionalised Socrates), Homer’s stories were composed to stir and entertain rather than to instruct us. They may be a lot of fun, but they have nothing to tell us about living well. How could fictional characters, shadowy beings who exist only in words, offer any meaningful purchase on the all too solid problems of our daily lives?If we try to enlist the help of novels by extracting rules and hacks and counsel from them, we will probably prove Plato right. Novels, or at least the ones worth reading, draw us in not by offering moral instruction or practical guidance, but by helping us to see ourselves in all our strangeness and complexity.

More than 350 clinicians report suspicions of Covid-induced diabetes, both type 1 and type 2A cohort of scientists from across the world believe that there is a growing body of evidence that Covid-19 can cause diabetes in some patients.Prof Francesco Rubino, from King’s College London, is leading the call for a full investigation into a possible link between the two diseases. Having seen a rise in both type 1 and type 2 diabetes in people who have caught coronavirus, some doctors are even considering the possibility that the virus ‒ by disrupting sugar metabolism ‒ could be inducing an entirely new form of diabetes.

University College London’s Marcel Levi talks openly about what he loves and loathes about the health serviceA service so underfunded that hospital roofs leak, is worryingly reliant on overseas staff and with an “insular” culture that repels fresh ideas – but which has also performed superbly to save lives during the Covid pandemic. After four years running one of Britain’s biggest hospitals Prof Marcel Levi has some strong views on the NHS and the government’s stewardship of the nation’s most venerated institution.Levi feels able to speak candidly because he is about to step down as the chief executive of University College London Hospitals trust and return to his homeland in the Netherlands to become its chief scientific officer so no longer fears upsetting NHS bosses. His views offer a counterpoint to the relentless positivity of the government’s airy promises to hire 50,000 more nurses and 6,000 more GPs, build 40 new hospitals and put in record funding.

Astroscale hopes its Elsa-d satellite will demonstrate a system to remove unwanted pieces of junkElsa-d, the world’s first commercial mission to demonstrate a space debris removal system, is scheduled to launch at 06:07 GMT on 20 March from the Baikonur cosmodrome in Kazakhstan.Developed by Astroscale, a Japanese-UK company, the mission will be operated from the UK’s in-orbit servicing control centre (IOCC) at Satellite Applications Catapult in Harwell, near Oxford. The End-of-Life Services by Astroscale demonstration mission (Elsa-d) is a small satellite designed to find, rendezvous and clamp on to an unwanted satellite. It will then push it into the Earth’s atmosphere, where it will burn up. Continue reading...
New species were discovered in the International Space Station – but they probably didn’t come from outer spaceFour species of bacteria – three of them previously unknown to science – have been discovered onboard the International Space Station (ISS), begging questions about how they got there, and how they have managed to survive.Their discovery may also bolster future efforts to cultivate crops during long spaceflight missions, since related species are known to promote the growth of plants and help them fight off pathogens.

My colleague Alan Clements, who has died aged 93 of Covid-19, was a medical entomologist whose research was dedicated to investigating novel methods of mosquito control.Mosquitoes get a bad press. They transmit tropical pathogens that lead to 700,000 deaths per year and their persistent bites can be unbearable. However, their role in the spread of diseases such as malaria is entirely passive. In addition, mosquitoes are a key source of food for a wide range of birds, bats, insects and fish. The more we learn about mosquito biology, the greater our chances of reducing or even eliminating mosquito-borne diseases. Continue reading...

Nanoparticles found in foetal brains and hearts, but impact on human health is as yet unknownTiny plastic particles in the lungs of pregnant rats pass rapidly into the hearts, brains and other organs of their foetuses, research shows. It is the first study in a live mammal to show that the placenta does not block such particles.The experiments also showed that the rat foetuses exposed to the particles put on significantly less weight towards the end of gestation. The research follows the revelation in December of small plastic particles in human placentas, which scientists described as “a matter of great concern”. Earlier laboratory research on human placentas donated by mothers after birth has also shown polystyrene beads can cross the placental barrier. Continue reading...
By the time mental ill health is visible, it’s probably very bad. The best risk assessment is to listen rather than lookIn my everyday life, when I see someone who looks happy, I expect them to feel like that, too. I don’t think about it particularly – it’s a reflex. I glance casually at a smiling face and am reassured that all is well. It takes a conscious effort to remind myself of a fact that psychiatrists know very well on an intellectual level but should perhaps recognise more: a cheerful demeanour can be profoundly misleading.The concept of the “happy” depressive is familiar in art and life, with examples ranging from Pagliaccio to Robin Williams. It seems strange to think that people can be very depressed – with all the debilitating symptoms that entails – yet manage to hide this, sometimes even from family. Is their depression as real, or as valid, because they manage to go to work, to smile, even to crack a joke? I think it is. There may come a point when even the happy depressive will crack, unable to maintain that facade any longer. But does that mean they suffer less when smiling? No: in fact, the strain of keeping up appearances, the weight of a misplaced sense of responsibility to others, can be one of the most onerous aspects of mental ill health. The loss of the smile may even be a relief. Continue reading...
Perseverance could perhaps do with a service as Nasa experts investigate unexpectedly high-pitched scratching noiseNasa’s newest Mars rover has sent back the first-ever sounds of driving on the red planet – a grinding, clanking, banging affair that by Earth standards would be pretty worrisome.The noises made by Perseverance’s six metal wheels and suspension on the first test drive two weeks ago are part of a 16-minute raw audio feed released on Wednesday by Jet Propulsion Laboratory in Pasadena, California.

From electrons behaving as both particles and waves to a cat in a box that’s both dead and alive, the consequences of quantum physics are decidedly weird. So strange, that over a century since its conception, scientists are still arguing about the best way to understand the theory. In the second of two episodes, Ian Sample sits down with the physicist Carlo Rovelli to discuss his ideas for explaining quantum physics, and what it means for our understanding of the world Continue reading...
$15m grant comes despite TGA’s failure to reschedule MDMA and psilocybin from a prohibited substance to a controlled medicineThe use of magic mushrooms, ecstasy and other psychedelic drugs to treat mental illnesses, including depression and post-traumatic stress disorder, may be a step closer in Australia, with clinical trials given a $15m grant.Despite international evidence suggesting the medicinal effectiveness of psychedelic drugs to treat mental health conditions, the Australian Therapeutic Drug Association last month made an interim decision against rescheduling MDMA and psilocybin from a prohibited substance (schedule 9) to a controlled medicine (schedule 8).

Nasa's latest Mars rover, Perseverance, has sent back the sounds of its six metal wheels driving across the planet's surface. The recording was captured by one of its two onboard microphones, with Nasa releasing 16 minutes' worth. Engineers are investigating whether a high-pitched scratching noise is caused by electromagnetic interference or the rover's movement. Perseverance will continue to look for somewhere to launch the Ingenuity Mars Helicopter, a drone that it is carrying Continue reading...
Interstellar visitor likely made of frozen nitrogen, cookie-shaped rather than cigar, and not a comet or asteroid – while some stick to alien theoryOur solar system’s first known interstellar visitor is neither a comet nor asteroid as first suspected and looks nothing like a cigar. A new study says the mystery object is likely a remnant of a Pluto-like world and shaped like a cookie.Arizona State University astronomers report the strange 45-metre (148ft) object appears to be made of frozen nitrogen, just like the surface of Pluto, and Neptune’s largest moon, Triton.

Pioneer of perinatal medicine who brought about dramatic improvements in the survival chances and wellbeing of babiesThe paediatrician and perinatologist Peter Dunn, who has died aged 91, introduced many innovations and developments that contributed to the dramatic improvements seen over the last half century in the survival, with no increased long-term impairment, of pre-term (and term) babies.Largely due to his influence, newborn care emerged from its previous neglect to become a key specialty in paediatrics and child health; teamwork between obstetricians, midwives, neonatal paediatricians, nurses and others also benefited.

Cultured stem cells turn into blastoid ‘balls’, like natural blastocysts after egg fertilisationScientists have made clumps of human tissue that behave like early-stage embryos, a feat that promises to transform research into the first tentative steps of human development.The clumps of cells, named blastoids, are less than a millimetre across and resemble structures called blastocysts, which form within a few days of an egg being fertilised. Typically blastocysts contain about 100 cells, which give rise to every tissue in the body. Continue reading...
Presenter Johnny Vaughan, producers and participants remember the Channel 4 series that pretended to send participants into orbit from a Russian bootcamp, but mainly took place on an airbase in SuffolkIn December 2005, a group of outgoing twentysomethings were gathered in front of cameras on a remote airstrip. They had signed up for a reality TV series called Thrill Seekers and, after five months of auditions, they were about to find out the exact premise of the show. The host, Johnny Vaughan, told the excited gang: “You are about to become … the very first televised British space tourists.” They started screaming, jumping up and down and hugging each other. They were going into actual space!Except, they weren’t. Despite now lingering forgotten, Space Cadets, launched 15 years ago by Channel 4, was one of television’s biggest ever pranks. A meticulously executed televised stunt (costing a reported £5m) that wanted to test how far the limits of reality could be pushed. Could they convince a few members of the public that they had blasted off from a Russian space camp into the galaxy on a five-day orbit of the Earth? Continue reading...
Public safeguarder of patients’ confidential information following a career as a mental health consultantThe invasion of information technology into healthcare brought the ancient principle of confidentiality between doctor and patient into conflict with opportunities to store and share data collectively.Fiona Caldicott, who has died aged 80, devoted the last 25 years of her life to resolving this issue within the UK National Health Service. She chaired three government reviews of information governance and in 2014 became the first National Data Guardian, appointed to “advise and challenge the health and care system to help ensure that citizens’ confidential information is safeguarded securely and used properly”.

Why does South Africa pay twice as much for vaccines as European countries? Why has Africa - home to 1.3bn people – been allocated just 300m doses?Last year, European and North American countries managed to ignore warnings of a highly contagious pandemic – dragging their feet in setting protocols in place, delaying mandatory mask-wearing, and giving mostly miserly handouts to the millions struggling to survive in lockdown. Though the virus originated in China, not the west, western countries imagined that the virus would not touch them in quite the same way: Europe and the US entertained the fantasy that they alone were the captains of a more sophisticated political and bureaucratic system that could not only withstand a global pandemic but also remain largely immune to its threats. This year, these same countries have managed to outdo themselves by vacating their role on the international stage – hoarding vaccines and practicing only the most expedient, shallow pretenses of vaccine diplomacy. The wealthiest western nations have wiped their hands clean of any responsibility to slow a pandemic they helped magnify and spread.Rich countries with 14% of the world’s population have secured 53% of the best vaccines. Almost all of the Pfizer/BioNTech vaccines will go to rich countries. The Moderna vaccine will go to rich countries exclusively; it is not even being offered to the poor. In fact, nine out of 10 people in poor countries may never be vaccinated at all. Washington is sitting on vaccines, making sure no one gets any while the US needs them. The European Union has exported 34m doses to, of all places, Singapore, Saudi Arabia and Hong Kong – countries that have no problem sourcing or paying for vaccines. In fact, the EU sent about 9m doses to the UK, a country which, no longer in the EU, also has what amounts in practice to an export ban of its own, official denials notwithstanding.

Finding raises questions about virus’s ability to lurk long term in outwardly healthy bodiesAn Ebola survivor is likely to have triggered the current outbreak in Guinea, scientists have said, in a shock discovery that means the virus may remain dormant for five years.The finding, which comes after 29 cases and 13 deaths, raises fresh questions about the ability of Ebola to lurk in the body long term even while the survivor remains outwardly healthy.

Sapria himalayana has lost about 44% of genes normally found in flowering plantsSapria is an extraordinary plant. It has no leaves, stem or root, can’t make food by photosynthesis, and exists almost its entire life as threads of cells sucking out all its nourishment from vines growing in the rainforests of Borneo. The only time the parasite reveals itself in the open is when it bursts out as a huge flower the size of a dinner plate, coloured red with pale speckles, and stinking of rotting flesh. It’s also a relative of the largest flower in the world, Rafflesia arnoldii, another parasitic plant.Recently, another bizarre feature of Sapria has been revealed. The species Sapria himalayana has lost about 44% of the genes normally found in flowering plants, and has also totally scrapped all the genetic remnants of any chloroplasts, the cell bodies that perform photosynthesis, the first known case of a plant abandoning its chloroplast inheritance. Although other parasitic plants have junked many of their genes, it’s nothing like as extreme as Sapria – the dodder parasite, for example, has only lost 16% of its genes. And to cap its extreme parasitic life, Sapria has also stolen more than 1% of its genes from its host vine. Continue reading...

Port Moresby General Hospital is one of the few safe places for women to give birth, but 30% of our workforce has Covid-19 and we may have to shut our doorsAt Port Moresby General Hospital, about 20% of women presenting in labour have symptoms of Covid-19. Of these, about one-third (four to five women a day) test positive.We get the test results back about two to three hours after we take the swabs, so often by the time the woman is delivering her baby it is too late to transfer her to the Covid isolation ward for the birth and staff have attended to her and been exposed to the virus, without being able to don the appropriate level of PPE and practice other precautionary measures to protect themselves.

Creation of mini-organs using stem cells will help research into tear-related disordersStop your sobbing – because scientists can do it for you. Using stem cells, Dutch researchers have grown miniature human tear glands capable of “crying”.Initially, when scientists were looking at developing this technology, their first port of call was the inner lining of the gut, because it replaces itself every five days. They took a tiny piece of gut tissue filled with stem cells and fed it proteins called growth factors to stimulate cell growth, expecting the stem cells to rapidly proliferate. Continue reading...

It has been over a century since the groundwork of quantum physics was first formulated and yet the strange consequences of the theory still elude both scientists and philosophers. Why does light sometimes behave as a wave, and other times like a particle? Why does the outcome of an experiment apparently depend on whether the particles are being observed or not? In the first of two episodes, Ian Sample sits down with physicist Carlo Rovelli to discuss the strange consequences of quantum and the explanation he sets out in his new book, Helgoland Continue reading...
My friend and colleague Don Mason, who has died aged 86, will be remembered for his discoveries about cells of the body’s immune system, notably the regulation of lymphocytes, and how fast and with what specificity their receptors recognise parts of foreign molecules.He began this work in 1973, joining the Medical Research Council’s cellular immunology unit in the Dunn School of Pathology, Oxford University. He stayed for 26 years until his retirement in 1999, by which time he was its director. Continue reading...

Archaeologist says ability to think and create objects may not have been restricted to homo sapiensWhen Neanderthals, Denisovans and homo sapiens met one another 50,000 years ago, these archaic and modern humans not only interbred during the thousands of years in which they overlapped, but they exchanged ideas that led to a surge in creativity, according to a leading academic.Tom Higham, a professor of archaeological science at the University of Oxford, argues that their exchange explains “a proliferation of objects in the archaeological record”, such as perforated teeth and shell pendants, the use of pigments and colourants, decorated and incised bones, carved figurative art and cave painting: “Through the early 50,000s, up to around 38,000 to 40,000 years ago, we see a massive growth in these types of ornaments that we simply didn’t see before.” Continue reading...
