Rare butterflies thriving after reintroduction bid

The large heath butterfly was once so widespread that it was locally named the Manchester argus. But its habitat was wrecked by the 19th Century arrival of the Liverpool and Manchester Railway. Wildlife experts said they were "optimistic" about the species, which is now "breeding strongly".

We’ve pumped so much groundwater that we’ve nudged the Earth’s spin, says new study

By pumping water out of the ground and moving it elsewhere, humans have shifted such a large mass of water that the Earth tilted nearly 80 centimeters (31.5 inches) east between 1993 and 2010 alone, according to a new study published in Geophysical Research Letters.

How traditional Indigenous education helped four lost children survive 40 days in the Amazon jungle

Indigenous children typically learn from an early age how to open paths through dense vegetation, how to tell edible from non-edible fruits. They know how to find potable water, build rain shelters and set animal traps. They can identify animal footprints and scents—and avoid predators such as jaguars and snakes lurking in the woods.

Urban great tits less stressed than their countryside cousins, finds study

"The great tit's high cognitive capacity means it is highly adaptable, and urban great tits seem to have adapted so well to the new environment that they are not stressed by high population density. Another possible explanation is that it was the most intelligent and most flexible individuals who succeeded in colonizing urban environments in the first place," says Anders Brodin, biologist at Lund University.

Climate change has increased diversity of butterflies in Sweden and Finland, may have major ecosystem consequences

New research shows that butterflies have expanded their ranges over the past 120 years to cope with a warmer climate in Sweden and Finland. Although driven by a warmer climate, range expansions have also been influenced by human land use and vary according to species thermal tolerances and habitat preferences.

How seeing corpses reduces the lifespan of flies

Researchers led by Christi Gendron at the University of Michigan have found the link between death perception and reduced aging in flies. [A] specific group of brain cells in the fly, called R2 and R4 neurons, are activated when flies encounter other dead flies, and that this increased activity leads to more rapid aging.

Cause and Cure Discovered for Common Type of High Blood Pressure

The cause is a tiny benign nodule, present in one-in-twenty people with hypertension. The nodule produces a hormone, aldosterone, that controls how much salt is in the body. […] The researchers also discovered that this form of hypertension could be cured by unilateral adrenalectomy – removing one of the two adrenal glands.

Hidden carbon: Fungi and their ‘necromass’ absorb one-third of the carbon emitted by burning fossil fuels every year

[New] research shows [mycorrhizal fungi] may quietly be playing a bigger role in storing carbon than we thought. [Researchers] estimate the world's plants are transferring a staggering 3.58 billion tonnes of carbon per year to this underground network.

Invasive oak processionary moth caterpillars cause concern for England’s trees

An insect that can be hazardous to human health is spreading across southeast England. […] "As the oak processionary moth is a relatively recent arrival to the UK, any potential predators haven't had much time to familiarize themselves with it. This means the caterpillars are able to spread faster than they would otherwise."

Wolves in Minnesota switch to fish as a main source of food in the spring

A team of wildlife specialists from the University of Minnesota, the University of Manitoba and Voyageurs National Park has found […] that wolves do, in fact, catch and eat fish, almost exclusively in the spring. This was because deer are a less reliable food source due to reductions in population each year over the hunting season.
