Leading scientist attacks prime minister as criticism mounts of government approach to science during the crisis

Rishi Sunak is facing a barrage of criticism in the run-up to the official Covid-19 inquiry as a leading scientist attacks his “spectacularly stupid” Eat Out to Help Out scheme, which is believed to have caused a sudden rise in cases of the virus.

The prime minister’s role as chancellor during the pandemic is under increasing scrutiny – as is that of his predecessor at No 10, Boris Johnson – in an escalating Covid blame game at Westminster as Lady Hallett prepares to open her investigation into the government’s pandemic response later this month.

Discovery of GS-9209, one of the furthest from the Milky Way, adds to evidence that large black holes prevent star formation, astronomers say

A supermassive black hole discovered at the heart of an ancient galaxy is five times larger than expected for the number of stars it contains, astronomers say.

Researchers spotted the immense black hole in a galaxy known as GS-9209 that lies 25bn light-years from Earth, making it one of the most distant to have been observed and recorded.

Citations of Chinese research have risen because of sequencing of Covid-19 genome

China has overtaken the US to become the biggest contributor to nature-science journals, in a sign of the country’s growing influence in the world of academic research.

The Nature Index, which tracks data on author affiliations in 82 high quality journals, found that authors affiliated with Chinese institutions are more prolific than their US counterparts in physical sciences, chemistry, Earth and environmental sciences. The only category in which the US is still in the lead is life sciences.

Limits on numbers at Paris summit mean some of those ‘most needing to be heard’ will not be in attendance

Scientists and NGOs have accused the UN’s environment programme (Unep) of locking out those “most needing to be heard” from upcoming negotiations in Paris aimed at halting plastic waste.

Last-minute restrictions to the numbers of NGOs attending what the head of Unep described as the “most important multilateral environmental deal” in a decade will exclude people from communities in developing countries harmed by dumping and burning of plastic waste as well as marginalised waste pickers, who are crucial to recycling, from fully participating, they said.

Ten-year science strategy of UK Health Security Agency will use data to combat infectious diseases faster and more effectively

Health officials in the UK have drawn up plans for a “genomics transformation” that aims to detect and deal with outbreaks of infectious diseases faster and more effectively in the light of the Covid pandemic.

Information gleaned from the genetics of Covid proved crucial as the virus swept around the globe, revealing how the pathogen spread, evolved, and responded to a succession of vaccines and medicines developed to protect people.

Anger at decision to axe the main task of the New Horizons spacecraft to probe the remote Kuiper belt

It may have reached the edge of the solar system and travelled more than 5 billion miles through space, but the New Horizons spacecraft is causing major ripples on Earth. A dispute has erupted between scientists and US space officials in the wake of Nasa’s decision to stop funding next year for the vessel’s main mission.

The move was described as “misguided and unfortunate” by Alan Stern, New Horizons’s principal investigator.

Fears over proliferation of disinfectant wipes linked to health problems

Researchers say wipes common in schools and care homes exposing people to dangerous chemical group called ‘quats’

Since the pandemic’s outset, the global use of disinfectants has gone through the roof. Clorox dramatically boosted production of its wipe packs to 1.5m a day by mid-2021, and an industry trade group said 83% of consumers surveyed around the same time reported they had used a disinfectant wipe in the last week.

But as schools reopened, a group of toxic chemical researchers grew concerned as they heard reports of kids regularly using disinfectant wipes on their classroom desks, or teachers running disinfectant foggers.

Some of the first humans to arrive in the Americas included people from what is now China, who arrived in two distinct migrations during and after the last ice age, a new genetics study has found.

“Our findings indicate that besides the previously indicated ancestral sources of Native Americans in Siberia, the northern coastal China also served as a genetic reservoir contributing to the gene pool,” said Yu-Chun Li, one of the report authors.

Elk tooth pendant unearthed in Siberia is first prehistoric artefact to be linked to specific person using genetic sleuthing

Scientists have used a new method for extracting ancient DNA to identify the owner of a 20,000-year-old pendant fashioned from an elk’s canine tooth.

The method can isolate DNA that was present in skin cells, sweat or other body fluids and was absorbed by certain types of porous material including bones, teeth and tusks when handled by someone thousands of years ago.
