New biology curriculum: thinking like a scientist

The new draft examination syllabuses for biology ask pupils to reason more explicitly and give teachers clearer guidance, even as the school subject of biology is reduced in scope.

Flight can be almost free for birds

By exploiting air currents, birds can save a great deal of energy during flight. Many large birds thus cover vast distances with virtually no effort.

The ovary keeps changing long after the menopause

The human ovary continues to undergo molecular changes for decades after the menopause.

Unusual mass die-off of Adélie penguins was not caused by bird flu

In the Antarctic summer of 2023/2024, Adélie penguins did not die en masse from bird flu, but from avian...

‘Why is sexual and gender-based violence still so prevalent in fieldwork?’

Fieldwork is not simply research conducted elsewhere. Isolation, hardship and social dynamics expose women to sexual and gender-based violence, writes Eve Afonso.

Guppies seek company when food beckons

Wild guppies spend twice as much time near conspecifics when food becomes available unexpectedly and briefly. By seeking company more often, they appear to increase their chances of finding food.

A two-cylinder engine in nature? How bees keep pumping venom with a detached stinger

When a bee stings, the sting tears free from its abdomen. Yet even after detaching, it continues to bore deeper into the skin and pump venom. How the sting manages this independently had long been a mystery. Australian biologists have used high-speed cameras to reveal what lies within this stinging organ: a biological micropump with a double piston provides a constant supply of venom, even after the sting has come free (PNAS, 12 October).

Are visitor centres essential for nature conservation?

Staatsbosbeheer wants to close its seven outdoor centres and reorganise public outreach in a different way. Following a wave of responses, the organisation has temporarily postponed the final decision and the centres will remain open for longer. But the question remains: are such physical spaces necessary for nature conservation?

Gut microbiome influences fever after vaccination

People with large numbers of flagellin-producing gut bacteria appear to respond more strongly to an mRNA vaccine.

‘We need to tell stories to communicate our knowledge of nature’

Long-lived migratory birds experience a great deal, and thanks to new and established techniques all of it can be tracked in precise detail. Wouter Vansteelant loves telling stories about the birds and his research. 'People respond to them with enthusiasm.

Peanut vs. Duke: DNA-labels predict that small dogs outlive their larger cousins

Small dogs generally live longer than large dogs. American research shows that this difference in ageing rate is also reflected in the epigenetic profile of dogs.

Elevation differences help plants cope with salinity

Bare hollows in a Dutch coastal grassland capture salt, allowing plants on vegetated mounds to grow better and remain green for longer.
