Rhinotillexis may be underestimated cause of transmission between staff, say researchers

Nose-picking should be given greater consideration as a potential health hazard, researchers have said, after finding healthcare workers who engaged in rhinotillexis were more likely to catch Covid than those who refrained.

Scientists in the Netherlands say research has previously found healthcare workers who had direct contact with Covid patients were more likely to catch Covid than those who did not.

Fossils found in Peru from extinct species show it may have had body mass of 85-340 tonnes – heavier than blue whales

The fossilised bones of an ancient creature that patrolled coastal waters 40m years ago belong to a newly discovered species that is a contender for the heaviest animal ever to have existed on Earth.

Fossil hunters discovered remnants of the enormous and long-extinct whale in a rock formation in the Ica desert of southern Peru. Fully grown adults might have weighed hundreds of tonnes, researchers believe.

Cells taken without consent from cancer victim can reproduce indefinitely and were sold for unjust profit by Thermo Fisher Scientific, relatives argued

Laboratory equipment maker Thermo Fisher Scientific has settled a lawsuit brought by the estate of Henrietta Lacks, a long-deceased cancer victim whose “immortal” cells have lived on to fuel biomedical research for decades, lawyers for the estate have said.

The story of Lacks, a young African American woman who died in Baltimore in 1951, was made famous in Rebecca Skloot’s 2010 book The Immortal Life of Henrietta Lacks, which became a movie in 2017 featuring Oprah Winfrey.

Leading scientists and medics back London and other clean air schemes and urge politicians to keep their nerve

Leading doctors and scientists have warned politicians against watering down plans to expand city-wide schemes aimed at reducing traffic pollution levels linked to thousands of deaths each year.

They urged politicians not to lose their nerve over plans to improve poor air quality, such as the expansion of the ultra low emission zone (Ulez) in London, which they said were central to tackling “unacceptably high” levels of illness and child deaths, and called for more ambitious policies to reduce toxic air.

Archaeologists hail ‘exceptional finds’ at venue whose existence was previously known only from mentions in ancient texts

The ruins of Nero’s Theatre, an imperial theatre referred to in ancient Roman texts but never found, have been discovered under the garden of a future Four Seasons hotel, steps away from the Vatican.

Archaeologists in Rome have excavated deep under the walled garden of the Palazzo della Rovere since 2020 as part of planned renovations on the frescoed Renaissance building. The palazzo, which takes up a city block along the broad Via della Conciliazione leading to Saint Peter’s Square, is home to an ancient Vatican chivalric order that leases the space to a hotel to raise money for Christians in the Holy Land.

European Space Agency to attempt unprecedented manoeuvre despite craft not being designed for controlled re-entry

A defunct European satellite is expected to make an unprecedented return to Earth on Friday when mission controllers guide the spacecraft into a fiery dive over the Atlantic Ocean.

The Aeolus weather-monitoring satellite was not designed for a controlled re-entry at the end of its mission, but the European Space Agency (Esa) has decided to use what little fuel remains onboard to steer the probe to a watery grave.

Zambia study finds egg variability and random nest selection by cuckoos helps fork-tailed drongos rumble impostors

Cuckoos might be the ultimate avian con artists, laying lookalike eggs in the nests of other birds to avoid raising their own young, but researchers say at least one potential victim is remarkably good at rumbling the fraud.

Scientists studying the African cuckoo have revealed that while the birds are able to produce almost identical-looking eggs to those of the fork-tailed drongo, the latter is likely to reject an impostor egg about 94% of the time.

Discovery in China challenges view of early mammals as ‘fodder’ for dinosaurs, say researchers

Whether they had sharp teeth, vicious claws or were simply enormous, dinosaurs were creatures to be feared. But a newly identified fossil shows that, at least sometimes, the underdog bit back.

Experts revealed the 125m-year-old fossil that froze in time after being taken on by a small mammal a third of its size. They are tangled together, the mammal’s teeth sunk into the beaked dinosaur’s ribs, its left paw clasping the beast’s lower jaw.

Chandrayaan-3 launches from island in southern India in follow-up to failed effort four years ago

An Indian spacecraft has blazed its way towards the far side of the moon in a follow-up mission to its failed effort nearly four years ago to land a rover softly on the lunar surface, India’s space agency said.

Chandrayaan-3, the word for “moon craft” in Sanskrit, took off from a launch pad in Sriharikota, an island in southern India, with an orbiter, a lander and a rover, in a demonstration of India’s emerging space technology. The spacecraft will embark on a journey lasting slightly over a month before landing on the moon’s surface later in August.

Scientists studied jewelry made from now extinct creatures and theorize that humans arrived in Americas 27,000 years ago

New research suggests humans lived in South America at the same time as now extinct giant sloths, bolstering evidence that people arrived in the Americas earlier than once thought.

Scientists analyzed triangular and teardrop-shaped pendants made of bony material from the sloths. They concluded that the carved and polished shapes and drilled holes were the work of deliberate craftsmanship.

Dutch study identifies several examples of corvids’ ‘amazing’ ability to adapt to the urban environment

Birds have never shied away from turning human rubbish into nesting materials, but even experts in the field have raised an eyebrow at the latest handiwork to emerge from urban crows and magpies.

Nests recovered from trees in Rotterdam in the Netherlands and Antwerp in Belgium were found to be constructed almost entirely from strips of long metal spikes that are often attached to buildings to deter birds from setting up home on the structures.

More people are making it to 100, but there’s little change in the proportion of ‘supercentenarians’, a report has found

Despite average life expectancy increasing, the proportion of Australians making it to age 110 has barely shifted since the 1960s, with a new report asking whether there is a limit to how far lifespan can be pushed.

The Australian Institute of Health and Welfare (AIHW) on Tuesday published its How long can Australians live? report, containing the latest life expectancy and longevity data. Over the past five decades, life expectancy in Australia has increased by 13.7 years for males (to 81.3) and by 11.2 years for females (to 85.4).
