Davina Cooper questions the need to use xenophobic terms to describe speciesThe widely used language of alien and invasive species threatening native ones (Increase in invasive species poses dramatic threat to biodiversity – report, 15 July) is disturbing, even when it’s about plants. There is a long-running debate in biology about the nativist and xenophobic resonances, and racist and antisemitic histories, surrounding claims that foreign plants and wildlife invade, take over and wipe out domestic species, upsetting the “natural” balance.Racism works through commonsense meanings and ideas, and these don’t have to be about people. Clearly, some plants and animals cause harm or create change, including by impeding biodiversity. But surely there is a public language to talk about these problems away from the pervasive terms of native and alien, with its dangerous implication that certain things belong, have always been at home here and form part of a proper (even timeless) balance, which the incomer upsets.

Solar Orbiter images shot from between Venus and Mercury orbits show ‘campfires’ in coronaThe closest ever images of the sun reveal its surface is speckled with “campfires”, miniature versions of the dramatic solar flares visible from Earth.The observations, beamed back from the Solar Orbiter spacecraft, which is a joint Nasa and European Space Agency (ESA) mission, could help resolve why the sun’s atmosphere is so staggeringly hot compared to the surface – a central paradox in solar physics. Miniature flares have been proposed as a theoretical explanation for the so-called coronal heating problem, but until now no telescope has had a good enough resolution to observe the sun’s atmosphere in sufficient detail.

Experts say signs are promising but there is a long way to go to show vaccine works

Letter also signed by Greta Thunberg urges EU leaders to act immediately on global heatingGreta Thunberg and some of the world’s leading climate scientists have written to EU leaders demanding they act immediately to avoid the worst impacts of the unfolding climate and ecological emergency.The letter, which is being sent before a European council meeting starting on Friday, says the Covid-19 pandemic has shown that most leaders are able to act swiftly and decisively, but the same urgency had been missing in politicians’ response to the climate crisis.

Human fingerprint on record temperatures ‘has rarely, if ever, been clearer’, says reportThe record-breaking heatwave in the Siberian Arctic was made at least 600 times more likely by human-caused climate change, according to a study.Between January and June, temperatures in the far north of Russia were more than 5C above average, causing permafrost to melt, buildings to collapse, and sparking an unusually early and intense start to the forest fires season. On 20 June, a monitoring station in Verkhoyansk registered a record high of 38C. Continue reading...

Scientists ‘disappointed’ app has not been deployed since first one was scrapped

Bob Hamblett suspects Dominic Cummings had an economic reason for the U-turn. Simon Fairlie worries about the psychological implications. Plus letters from Jonathan Myerson, Andrew Firth, and Margaret DeighanMarina Hyde (Johnson has seen the light on ‘face coverings’. Just not the toxic mask-ulinity, 14 July) takes the PM at his word that it’s “the scientific evidence” that has brought about his very late conversion. Until recently his government was quoting experts who said face coverings would give the public a false sense of security. One can imagine the lightbulb moment in the office of his special adviser: if the public are too scared to come out and spend to rescue the economy, give them what they apparently want – a false sense of security. Classic Dom.

An ingredient in its bark led to aspirin, now researchers are looking into the properties of another compound in the treeWillow trees are a pharmaceutical treasure trove. The ancient Egyptians used its bark for relieving pain, inflammation and fevers, and science has since shown these medical powers came from an ingredient called salicin, named after salix, the Latin name for the tree. That discovery eventually led to the manufacture of aspirin, one of the most widely used medicines in the world.

Public urged to send in snaps of paintings to help unpick how produce has evolvedFrom the juicy grapes depicted by Clara Peeters to Cézanne’s colourful apples, fruit and vegetables have appeared on myriad canvases over the centuries. Now researchers want the public to send in their snaps of such paintings to help unpick how our produce has evolved.The duo behind the idea say harvesting such images could help shed light on the shapes and colours fruit and vegetables have taken over the years, as well as when and where such forms cropped up. They add it could even offer information on factors such as trade routes and food habits. Continue reading...

Edinburgh University team find heart damage in 55% of ultrasounds from 69 countries

In the 1990s, a troupe of hippies spent two years sealed inside a dome called Biosphere 2. They ended up starving and gasping for breath. As a new documentary Spaceship Earth tells their story, we meet the ‘biospherians’It sounds like a sci-fi movie, or the weirdest series of Big Brother ever. Eight volunteers wearing snazzy red jumpsuits seal themselves into a hi-tech glasshouse that’s meant to perfectly replicate Earth’s ecosystems. They end up starving, gasping for air and at each other’s throats – while the world’s media looks on.But the Biosphere 2 experiment really did happen. Running from 1991 to 1993, it is remembered as a failure, if it is remembered at all – a hubristic, pseudo-scientific experiment that was never going to accomplish its mission. However, as the new documentary Spaceship Earth shows, the escapade is a cautionary tale, now that the outside world – Biosphere 1, if you prefer – is itself coming to resemble an apocalyptic sci-fi world. Looking back, it’s amazing that Biosphere 2 even happened at all, not least because the people behind it started out as a hippy theatre group. Continue reading...

Jupiter is at its closest to Earth and directly opposite the sun – so will be conspicuous for its brightnessOn 14 July at 09:00 BST, Jupiter will be directly opposite the sun in the sky. Known as opposition, it marks the middle of the weeks when the planet is at its best for observing because it is closest to Earth. From Jupiter’s perspective, our world will be at inferior conjunction, meaning that it will be directly in-line with the sun. The chart shows the view looking south at midnight tonight from London. Jupiter will be quite low in the night sky, close to the main body of Sagittarius, the archer. It will be conspicuous because of its brightness and its proximity to another bright planet, Saturn.
