Findings could help predict how animals will adapt to climate breakdown and loss of habitatScientists have discovered the reason why some birds live fast, die young in findings that could help predict how animals will adapt to climate breakdown and habitat destruction.Research from the University of Sheffield has revealed why some bird species take longer to develop than others. The study, published in Nature Communications, is the first to consider the importance of lifestyle, environment, evolutionary history and body size when explaining variation. Continue reading...

Government chief adviser fails to give estimate of how many have arrived with Covid-19At least 95,000 people have entered the UK from overseas since the coronavirus lockdown was imposed, one of the government’s chief scientific advisers has revealed, while repeatedly failing to provide an estimate of how many of these people had Covid-19.Appearing before MPs on the science and technology committee, Prof John Aston, the chief scientific adviser at the Home Office, admitted that had tougher restrictions been introduced at the border, the peak of the virus may have been delayed – but he did not say by how long, or if this would have saved lives.

Digital scrutiny is imperfect but it has proved that the Commons can modernise. Ending the experiment prematurely is a backwards stepThere is still much to be learnt about the coronavirus, but it is clear that transmission is efficient in crowded, enclosed spaces. On that basis a full House of Commons is unsafe.That is why “hybrid scrutiny” was introduced, with most MPs contributing to debates remotely. It is an imperfect system but also a vital experiment in technological adaption by an institution that is slow to embrace modernity. Continue reading...

Electric charge released by radiation from nuclear testing thickened clouds thousands of miles away, research finds

The UK government has told the public to wear 'cloth face coverings' in crowded places where it's not possible to comply with physical-distancing measures, but what does this mean? Why not face masks? Outside too? Should anyone avoid wearing a face covering? The Guardian's health editor, Sarah Boseley, answers these and other questions

Analysis of samples from thousands of patients might point to genetic variations

About 20% of UK population vulnerable but not included in government’s shielding adviceEight million people with underlying health conditions should be exempted from plans to get the country back to work and normal life, according to scientists who warn that easing lockdown too quickly could propel the Covid-19 death toll to 73,000 this year.About 80% of the population have little to fear from a return to work, but 20% are vulnerable from one or more common conditions such as diabetes, obesity and heart problems, say researchers from University College London (UCL) in a Lancet study published on Wednesday.

Guidance published for businesses on how to operate safely; UK coronavirus death toll passes 40,000, official figures say; Reading and Leeds festivals cancelled

My colleague and friend Carol Ellison, who has died of cancer aged 58, was a scientist in the field of biological control of invasive species. This is a little-known but increasingly important tool in the management of alien weeds which, if unchecked, can destabilise ecosystems and constrain agriculture.Born in Croydon, south London, to Edward Ellison, a toolmaker, and his wife, Valerie (nee Rickard), Carol was a committed environmentalist from an early age. She graduated in biological sciences from the University of East Anglia and subsequently registered for an MSc in pest management at Imperial College London, during which she worked with me in Kenya as part of her thesis investigating the potential of fungal pathogens for the control of African grasses.

China, Denmark and Singapore expand testing; Spain to quarantine new arrivals; France bans drinking on Seine

The prime minister is handling coronavirus so badly now, he makes even his most unpopular predecessors look public-spiritedThough it majors in killing, coronavirus certainly enjoys a sideways glance at inequality. In April, we discovered that the British TV show Holby City owned only one fewer working ventilator than the African country Liberia. On Sunday, construction and manufacturing workers were told to get back to work by a man who skived off five consecutive Cobra meetings during a wildly mushrooming global epidemic. Five! Boris Johnson couldn’t even be bothered to turn up and grip the government’s crucial early response to a deadly virus – are we supposed to believe he’d be rushing back to finish a loft extension out of civic duty? He’s not even prime minister out of civic duty.Still, that’s showbiz. You miss one universal credit meeting and your benefits are stopped; you miss five Cobra meetings and you get to address the nation on its working responsibilities from a drawing room so vast you’d need a hansom cab to traverse it. (When are we de-furloughing the hansom cabbies? I don’t care if they are dead and from the 19th century: that’s hardly a bar to this government assessing them as fit for work.) Continue reading...
