[Perspectives] Physicians in the digital age

The Lancet - Sa, 15/01/2022 - 00:00
Artificial intelligence (AI) is here. We are now in decade of Philip K Dick's dystopian novel Do Androids Dream of Electric Sheep? and AI is already capable of driving our cars. But self-driving cars have harmed pedestrians and AI has been credited with delivering misinformation in curated social media feeds that threaten democracy. AI has also entered medicine, with uses in medical imaging and many other areas. However, there is increasing attention on how some algorithms in health care are racially biased.

[Correspondence] The UK People's Covid Inquiry

The Lancet - Sa, 15/01/2022 - 00:00
The People's Covid Inquiry anticipated that any official public investigation into the COVID-19 pandemic would be much delayed. It was a citizens’ tribunal —ie, part legal proceedings, part theatre, part publicly speaking truth to power—aimed at raising issues to more visible levels than government or the media were prepared to do on their own. The renowned human rights barrister, Michael Mansfield, acted as chair. A final report in December, 2021, set out conclusions and recommendations on the basis of the evidence collected.

Halperin SA, Ye L, MacKinnon-Cameron D, et al. Final efficacy analysis, interim safety analysis, and immunogenicity of a single dose of recombinant novel coronavirus vaccine (adenovirus type 5 vector) in adults 18 years and older: an international, multicentre, randomised, double-blinded, placebo-controlled phase 3 trial. Lancet 2021; 399: 237–48—In this Article, the third section of the Procedures section should have stated “A single 0·5 mL dose of either the Ad5-nCoV vaccine or placebo was administered to each participant in the deltoid muscle of the non-dominant arm.” This correction has been made to the online version as of Jan 13, 2022, and the printed version is correct.

[Clinical Picture] Ground glass opacities are not always COVID-19: a case of acute eosinophilic pneumonitis caused by daptomycin

The Lancet - Sa, 15/01/2022 - 00:00
An 83-year-old man was admitted to our hospital reporting a 3-week history of cough and exertional dyspnoea. At the time of admission, the patient was 4 weeks into a 6-week course of daptomycin and rifampicin because he had an infected prosthetic knee joint; he also had a history of pituitary hypoplasia and had not been vaccinated against SARS-CoV-2.

Portable laser scanner creates colour 3D images of surfaces or objects

New Scientist - Ve, 14/01/2022 - 18:37
Lidar uses lasers to create 3D images, but these can be hard to interpret because they are black and white. A new scanner adds cameras to make colour images that could be useful for infrastructure inspection or robot vision

A new milestone this week points to how these environmental levies are more likely the solution, not the problem, when it comes to avoiding energy price shocks

Why omicron isn't more severe in kids despite rise in hospitalisations

New Scientist - Ve, 14/01/2022 - 14:30
Reassuring findings from the UK and South Africa suggest that omicron isn't more severe in kids. Record numbers of hospitalisations probably reflect sheer number of cases and lack of vaccination

'Doomsday' shipwreck exposed by New Scientist finally being tackled

New Scientist - Ve, 14/01/2022 - 09:00
In 2004, my investigation into the bomb-laden wreck of the SS Richard Montgomery revealed the danger to people living nearby. Almost 20 years later, the UK government has finally agreed to do something about it

Strongest evidence yet that MS is caused by Epstein-Barr virus

Animal decline is hurting plants' ability to adapt to climate change

New Scientist - Gi, 13/01/2022 - 20:00
Declines in birds and mammals are hampering plants by curbing the dispersal of their seeds, in a "clear intersection of the biodiversity crisis heavily impacting the climate crisis"

Organic compounds on Mars were produced by water and rocks, not life

New Scientist - Gi, 13/01/2022 - 20:00
Molecules containing carbon atoms, called organics, have been found all over Mars and could hypothetically have been formed by living organisms, but it seems they were not

Long-lasting radiation shields may make super-Earths friendly for life

New Scientist - Gi, 13/01/2022 - 20:00
Life on Earth is made possible by our planet’s magnetosphere – an invisible radiation shield that protects the surface – now it turns out that super-Earths could have magnetospheres too

What endemic means - and why covid-19 is nowhere near it yet

New Scientist - Gi, 13/01/2022 - 18:46
The term "endemic" usually means that an infection is stable, not that it is less deadly or that protective measures are no longer required. With the omicron variant surging, covid-19 is unlikely to become endemic soon

The moon's magnetic field may have been altered by huge sinking rocks

New Scientist - Gi, 13/01/2022 - 17:00
There’s a new explanation for the moon’s former magnetic field, and it involves 60-kilometre-wide slabs of rock sinking through the lunar mantle
