DNA study confirms Christopher Columbus’s remains are entombed in Seville

Posted on by

Scientists have ‘definitively’ proved identity of remains – with navigator’s precise origins to be revealed

Scientists in Spain claim to have solved the two lingering mysteries that cling to Christopher Columbus more than five centuries after the explorer died: are the much-travelled remains buried in a magnificent tomb in Seville Cathedral really his? And was the navigator who changed the course of world history really from Genoa – as history has long claimed – or was he actually Basque, Catalan, Galician, Greek, Jewish or Portuguese?

The answer to the first question is yes. The answer to the second is … wait until Saturday.

Severe Covid infections can inflame brain’s ‘control centre’, research says

Posted on by

Scans of people hospitalised with Covid may explain the long-term breathlessness and fatigue some patients experience

Severe Covid infections can drive inflammation in the brain’s “control centre”, researchers say, leading to damage that may explain the long-term breathlessness, fatigue and anxiety some patients experience.

High-resolution MRI scans of 30 people hospitalised with Covid early in the pandemic, before the introduction of vaccines, found signs of inflammation in the brainstem, a small but critical structure that governs life-sustaining bodily functions such as breathing, heart rate and blood pressure.

Europe’s exhausted oyster reefs ‘once covered area size of Northern Ireland’

Posted on by

Study uncovers vivid and poignant accounts of reefs as high as houses off countries including UK, France and Ireland

Only a handful of natural oyster reefs measuring at most a few square metres cling on precariously along European coasts after being wiped out by overfishing, dredging and pollution.

A study led by British scientists has discovered how extensive they once were, with reefs as high as a house covering at least 1.7m hectares (4.2m acres) from Norway to the Mediterranean, an area larger than Northern Ireland.

The world is shifting away from using animals in research. Will Australia get left behind?

Posted on by

Australia’s lack of transparency and funding leave it on the outer as researchers worldwide explore alternatives for training, study and testing

A global shift in scientific and medical research is under way as countries hope to phase out experimentation on animals – but Australia risks being left behind.

The transition from using animals to alternatives based on human cells, tissue and data is driving multibillion-dollar growth in new technologies and methods. However, industry leaders and insiders warn Australia will miss those opportunities due to a lack of funding, opaque record keeping and national inconsistencies.

Archaeologists use AI to discover 303 unknown geoglyphs near Nazca Lines

Posted on by

Newly discovered figures dating back to 200BCE nearly double the number of known geoglyphs at enigmatic site

Archaeologists using artificial intelligence (AI) have discovered hundreds of new geoglyphs depicting parrots, cats, monkeys, killer whales and even decapitated heads near the Nazca Lines in Peru, in a find that nearly doubles the number of known figures at the enigmatic 2,000-year-old archaeological site.

A team from the Japanese University of Yamagata’s Nazca Institute, in collaboration with IBM Research, discovered 303 previously unknown geoglyphs of humans and animals – all smaller in size than the vast geometric patterns that date from AD200-700 and stretch across more than 400 sq km of the Nazca plateau.

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.
