While new study challenges assumptions about how far they travel, witnessing them in action still takes your breath away, scientists say

They may look like a fluffy flying carpet, but greater gliders are not as great at gliding as previously thought, Australian researchers have discovered.

The first study to measure the aerial ability of Australia’s largest gliding marsupial has found they soar across an average distance of 19 metres – far shorter than the 100 metres suggested in an 85-year-old study.

Researchers testing a cheap, homegrown oil in Uganda found what cats knew all along – it worked as well as the artificial chemical used globally

A homegrown catnip lotion has proven “just as effective as Deet” as a mosquito repellant in trials carried out in Uganda.

Catnip, or Nepeta cataria, is a common herb from the mint family. The chemical in the plant that causes feline euphoria – nepetalactone – also has insect-repelling properties but this has not previously been commercialised.

Cambridge experts recreate 336-year-old garden to commemorate ‘father of natural history’

Posted on by

John Ray, 17th-century botanist who coined words petal and pollen, was a tutor at Cambridge when he created his first garden

He coined the terms petal and pollen, helped to lay the foundations of modern biology and is widely regarded as the greatest English naturalist of the 17th century.

But it was while he was a young college tutor at Cambridge in the 1650s that the botanist John Ray – also known as “the father of natural history” – created his first known garden and began to systematically study plants for the first time.

Discovery in Siberia suggests bacterium from raw marmots devastated hunter-gatherer tribes about 5,500 years ago

The earliest evidence for an outbreak of plague has been uncovered at late stone age cemeteries in south-eastern Siberia where dozens of hunter-gatherers and their children were buried.

Ancient DNA collected from the remains suggests the disease tore through the sparse communities in devastating waves that began about 5,500 years ago, at least two centuries after the bacterium responsible, Yersinia pestis, first emerged.

AI could help win ‘race against extinction’ of vital plants, say botanists

Posted on by

Tech is helping to identify and save new specimens and could open ‘genomic goldmine’ of fungi data

The rise of AI and digitisation could be a turning point in the “race against extinction” faced by botanists trying to identify and save vital plants before they vanish, according to a major report from Royal Botanic Gardens, Kew.

New technology is enabling scientists to track how flowering times have shifted by weeks around the world, rapidly identify new specimens and even get crucial genetic data from 180-year-old fungus specimens, potentially opening a “genomic goldmine”. Digitisation and online access to millions of specimens that were until now only accessible in archives is also producing new insights, especially in the global south.

Geochronologists say Antrim coastline’s basalt columns developed over 5.5m years – 8m less than thought

For centuries, the tale has been passed from generation to generation: how the Irish giant Finn McCool built the Giant’s Causeway in Northern Ireland to fight Benandonner, his Scottish rival, by hurling chunks of the Antrim coastline into the sea.

Now, scientists have revealed it was intense volcanic activity during a “major globally impacting volcanic event” – and not a legendary battle between two destructive giants – that led to the formation of the coastline’s 40,000 distinctive interlocking basalt columns about 60m years ago.

Exclusive A vast area of the Bellingshausen Sea should be covered by sea ice by now, with one expert calling the loss of ice ‘depressing’

Antarctica’s west coast is missing an area of winter sea ice the size of France, sparking concerns for threatened penguins other marine life and global sea levels.

One expert said the loss of ice in the Bellingshausen Sea was “depressing” and the failure of ice to form could have intensified a heatwave over the continent’s peninsular last week that saw daytime temperatures peak at 15.4C which is more than 20C above average.

Doctors say therapy that genetically modifies person’s T-cells could offer cure for chronic autoimmune disease

Five lupus patients in England are in remission after being treated with a revolutionary therapy that genetically modifies their own cells, in a medical breakthrough that could offer people a cure, doctors have said.

CAR (chimeric antigen receptor) T-cell therapy involves removing a type of white blood cell also called T lymphocytes, which are crucial for hunting out infected or damaged cells, and engineering them to spot and destroy disease. The T-cells are then fed back into the patient via an infusion to reset their immune system.
