Race to combat mpox misinformation as vaccine rollout in DRC begins

Posted on by

Poll suggests half of Congolese have not heard of deadly disease, as conspiracy theories and rumours spread

For doctors and nurses fighting mpox in the Democratic Republic of the Congo, the virus itself is not the only enemy. They are also facing swirling rumours and misinformation.

The first of millions of promised doses of mpox vaccine have finally started to arrive. Now the focus is on ensuring that people who need them will take them when the vaccination campaign begins next month, and teaching wider communities how to protect themselves.

Healthier rice variety could counter rise in diabetes, Philippine scientists say

Posted on by

Researchers develop grain with lower glycaemic index and more protein that ‘could have big impact in Asia and Africa’

Scientists in the Philippines have created a new variety of rice that could help reduce the growing burden of diabetes.

More than 537 million adults worldwide are living with the chronic disease – a number that is expected to grow to 783 million by 2045. Being overweight, genetics and a lack of exercise contribute to type 2 diabetes, which is the most common form. Type 2 occurs when the pancreas fails to produce enough of the insulin hormone, leaving too much glucose in the blood, and cells develop a resistance to insulin.

A grey matter? Nature, nurture and the study of forming political leanings

Posted on by

Researchers find minuscule difference in the amygdala – a region of the brain linked to threat perception

Where does our personal politics come from? Does it trace back to our childhood, the views that surround us, the circumstances we are raised in? Is it all about nurture – or does nature have a say through the subtle levers of DNA? And where, in all of this, is the brain?

Scientists have delved seriously into the roots of political belief for the past 50 years, prompted by the rise of sociobiology, the study of the biological basis of behaviour, and enabled by modern tools such as brain scanners and genome sequencers. The field is making headway, but teasing out the biology of behaviour is never straightforward.

Enclosure older than Salisbury monument found under late novelist’s garden is given heritage protection

When the author Thomas Hardy was writing Tess of the D’Urbervilles in 1891, he chose to set the novel’s dramatic conclusion at Stonehenge, where Tess sleeps on one of the stones the night before she is arrested for murder.

What the author did not know, as he wrote in the study of his home, Max Gate in Dorchester, was that he was sitting right in the heart of a large henge-like enclosure that was even older than the famous monument on Salisbury Plain.

Scientific research on pigeon missiles and dead trout also win at awards for amusing studies with serious implications

In a stark demonstration of how award-winning breakthroughs can come from the most unlikely directions, researchers have won an Ig Nobel prize for discovering that mammals can breathe through their anuses.

After a series of tests on mice, rats and pigs, Japanese scientists found the animals absorb oxygen delivered through the rectum, work that underpins a clinical trial to see whether the procedure can treat respiratory failure.

Living microbes that cause disease in humans and host antibiotic-resistance genes carried 1,200 miles

Microbes that cause disease in humans can travel thousands of miles on high-level winds, scientists have revealed for the first time.

The winds studied carried a surprising diversity of bacteria and fungi, including known pathogens and, some with genes for resistance to multiple antibiotics. Some of the microbes were shown to be alive – in other words, they had survived the long journey and were able to replicate.

Eels use tail-first technique to back up digestive tract of fish towards oesophagus before coming out of gills

It sounds like the plot of a horror movie – a predator swallows its prey only for the creature to burst out of its captor’s body. But it seems Japanese eels do just that.

Scientists in Japan have discovered that when swallowed by a dark sleeper fish, the eels can escape.

Romans’ siege wall in Masada may have been built in a fortnight, study finds

New archaeological research adds to view that siege may have been quicker and more efficient than was thought

The Roman siege of Jewish rebels in Masada, one of the founding myths of modern Israel, may have been far quicker and more efficient and brutal than it has been traditionally represented as, according to new archaeological research.

The end of the AD72-73 Jewish Revolt is conventionally depicted as a heroic last stand against the might of Rome by a handful of rebels who eventually killed themselves rather than be overwhelmed by the emperor Vespasian’s forces.

Researchers discover how to use ‘olfactory misinformation’ to protect native animals and farmers’ crops

Peter Banks’ remarkable road to a prestigious Eureka prize began nearly two decades ago as he watched rodents escape predators and wondered: why were the mice peeing everywhere?

“They were just putting their smell everywhere,” the ecologist said. “And I went, ‘how about if we use that principle of the smell of prey being everywhere to stop predators from finding their food?’”

Maria Sibylla Merian’s beautiful and disturbing illustrations, which shaped how we look at the natural world, will be on show at Amsterdam’s Rijksmuseum

More than three centuries after she made a perilous transatlantic voyage to study butterflies, a rare copy of the hand-coloured masterwork by the great naturalist and artist Maria Sibylla Merian is returning to Amsterdam.

The Rijksmuseum, which holds more than half-a-million books on art and history, last week announced it had acquired a rare first-edition copy of Metamorphosis of the Insects of Suriname (Metamorphosis Insectorum Surinamensium), described as a high point of 18th-century book production when the Dutch Republic was “the bookshop of the world”.

‘Amazing’ Viking-age treasure travelled half the world to Scotland, analysis finds

Posted on by

Lidded vessel is star object in rich Galloway Hoard and came from silver mine in what is now Iran

It is a star object of the Galloway Hoard, the richest collection of Viking-age objects ever found in Britain or Ireland, buried in AD900 and unearthed in a field in Scotland. Now a lidded silver vessel has been identified as being of west Asian origin, transported halfway around the world more than 1,000 years ago.

When it emerged from the ground a decade ago, the vessel was still wrapped in its ancient textiles, whose survival is extremely rare. Its surface could be seen only through X-ray scans. Since then, the textiles have been partially removed and preserved and the vessel has had laser cleaning to remove green corrosion over much of its silver surface. It has also undergone scientific analysis.

US repeating Covid mistakes with bird flu as spread raises alarm, experts say

Posted on by

Public health experts warn ‘overinflated view of abilities’ and restrictive laws could make next outbreak more lethal

The US is making the same mistakes with the H5N1 bird flu virus as with Covid, even as the highly pathogenic avian influenza continues spreading on American farms and raising alarms that it could mutate to become a pandemic, public health experts argue in the New England Journal of Medicine.

“We’re closing our eyes to both the Covid pandemic and to a potential nascent bird flu [pandemic] on the horizon,” said Gregg Gonsalves, associate professor of epidemiology at the Yale School of Public Health and co-author of the article. “Our ability to react swiftly and decisively is the big problem.”
