'Body eruption': the aphids that sacrifice themselves for colony
Scientists study species that releases huge quantities of bodily fluids to plug nest holes
While humans might change their locks to deal with intruders, a species of aphid opts for a communal sacrifice, releasing huge quantities of a sticky bodily fluid to plug holes in their nests.
Researchers who studied the makeup of the fluid found the process for nest repair was similar to what happens when aphids are wounded, involving the release of substances that clot and form a scab. This means similar mechanisms underpin both individual immunity and so-called social immunity – when organisms work together to protect their communities from enemies and disease.

In the warmer months of the year the inland lake in Melbourne’s Westgate Park turns pink owing to high salt levels, sunlight and a lack of rainfall. But it’s not the only body of water in Australia to change hue. Here are some of the rose-coloured lakes across the country

Winds carry microplastics ‘everywhere' - even on to remote mountaintops
Study finds even supposedly pristine region of the Pyrenees is polluted, but impact on human health remains unknown
Microplastic is raining down on even remote mountaintops, a new study has revealed, with winds having the capacity to carry the pollution “anywhere and everywhere”.
The scientists were astounded by the quantities of microplastic falling from the sky in a supposedly pristine place such as the French stretch of the Pyrenees mountains. Researchers are now finding microplastics everywhere they look; in rivers, the deepest oceans and soils around the world.

Not a single leatherback nested at the Chacocente reserve this year as the species faces threats of poaching and warming seas
Every year, from November through March, leatherback sea turtles arrive to the secluded shores of the Río Escalante Chacocente wildlife reserve on Nicaragua’s Pacific coast to lay their eggs.
Though leatherback nesting habits vary, Chacocente has been a reliable egg-laying site for as long as conservationists have collected nesting data.

David Buckel hoped his death would catalyze action. But what is individual responsibility when confronted with the crisis of a rapidly changing planet?
- Warning: graphic content
On a recent Saturday in Brooklyn, against the unlikely backdrop of a huge blue-and-white Ikea outlet, several dozen volunteers hand-churned compost. Decomposing food scraps emit considerable heat, and the 6ft-tall compost heaps were warm to the touch. As shovels and pitchforks pierced the compost, gusts of steam rolled off like fog.
A three-acre lot-turned-urban farm, the Red Hook Community Farms contains the largest compost site in America powered entirely by sustainable sources. During an orientation for new volunteers, one of the site managers explained that the operation was the brainchild of a lawyer-turned-environmentalist named David Buckel, who supervised it until his death last year. He designed the site’s processes so it would run like clockwork, even in his absence.
