Already replete with sharks, crocodiles, snakes and poisonous jellyfish galore, Australia may also be home to arsonist birds that spread fire so they can feed on animals as they flee.
The belief that birds like the Whistling Kite, Black Kite and Brown Falcon spread grass fires goes back so far that it’s commemorated in indigenous ceremonial dances, according to Bob Gosford, a co-author of this paper in the Journal of Enthnobiology.
The paper posits that the behaviour isn’t accidental:
Most accounts and traditions unequivocally indicate intentionality on the part of three raptor species and a handful provide evidence of cooperative fire-spreading by select individuals from within larger fire-foraging raptor assemblages, it notes.
And while the researchers’ main interest was to confirm and document those stories, Gosford told Vulture South the research is also important to understanding how fire spreads in Australia.
This may give us cause to re-examine fire history, and the conduct of fire in this country, Gosford said — via The Register

Ancient Roman concrete marine structures built thousands of years ago are stronger now than when they were first built.
So how has Roman concrete outlasted the empire, while modern concrete mixtures erode within decades of being exposed to seawater?
Scientists have uncovered the chemistry behind how Roman sea walls and harbour piers resisted the elements, and what modern engineers could learn from it.
Romans built their sea walls from a mixture of lime (calcium oxide), volcanic rocks and volcanic ash, a study, published in the journal American Mineralogist, found.
Elements within the volcanic material reacted with sea water to strengthen the concrete structure and prevent cracks from growing over time.
It’s the most durable building material in human history, and I say that as an engineer not prone to hyperbole, Roman monument expert Phillip Brune told the Washington Post — via redwolf.newsvine.com

Forensic scientists say they have been overwhelmed by the number of people wanting to donate their corpses to the southern hemisphere’s first body farm.
The secret bushland facility on the outskirts of Sydney is being used to study how human bodies decompose.
It was established in early 2016 by Professor Shari Forbes, a forensic scientist from the University of Technology Sydney.
We’re not CSI, we don’t solve investigations in an hour, but we can solve investigations through the research that we do, Professor Forbes said.
The facility is currently the only body farm outside the United States and Professor Forbes said the public interest had been higher than anyone had expected.
The level of interest has definitely surprised us, she said.
We already have 30 of our donors who have arrived at our facility, and that’s in just over a year.
We weren’t expecting anywhere near that number.
More than 500 people have now said they will also donate their bodies to the cause once they die.
We do have a slight bias towards seniors and the elderly, thankfully because they live long and healthy lives and intend to die from natural causes, Professor Forbes said.
We don’t hope to see young people out there, but the few that arrive are really beneficial to the work that we do for the police — via redwolf.newsvine.com
When you examine the lives of history’s most creative figures, you are immediately confronted with a paradox: They organize their lives around their work, but not their days.
Figures as different as Charles Dickens, Henri Poincaré, and Ingmar Bergman, working in disparate fields in different times, all shared a passion for their work, a terrific ambition to succeed, and an almost superhuman capacity to focus. Yet when you look closely at their daily lives, they only spent a few hours a day doing what we would recognize as their most important work. The rest of the time, they were hiking mountains, taking naps, going on walks with friends, or just sitting and thinking. Their creativity and productivity, in other words, were not the result of endless hours of toil. Their towering creative achievements result from modest
How did they manage to be so accomplished? Can a generation raised to believe that 80-hour workweeks are necessary for success learn something from the lives of the people who laid the foundations of chaos theory and topology or wrote Great Expectations?
I think we can. If some of history’s greatest figures didn’t put in immensely long hours, maybe the key to unlocking the secret of their creativity lies in understanding not just how they laboured but how they rested, and how the two relate — via redwolf.newsvine.com

A new approach to target and kill destructive feral cats is being developed in South Australia, in a bid to help save threatened native animals.
The task of reducing the feral cat population has been difficult due to the lack of effective and humane broad-scale control techniques.
In a lab at the University of South Australia, researchers have created a rice-sized implant that can be injected into native animals, making them toxic to feral cats.
Anton Blencowe, polymer chemistry expert at the university, said it was a unique approach that could help safeguard a range of endangered species.
It’s got a toxin in the middle, and then it’s got a special coating around the outside so that we can make the animals toxic to cats, he said.
But at the same time make sure the implant is not toxic to native animals.
The implant contains a natural poison from seeds of native plants and is covered by protective coating.
It remains inert until it comes into contact with the feral cat, and while it’s harmless to the native animal, to the predator it’s highly deadly once ingested — via redwolf.newsvine.com
Archaeologists investigating human bones excavated from the deserted mediaeval village of Wharram Percy in North Yorkshire have suggested that the villagers burned and mutilated corpses to prevent the dead from rising from their graves to terrorise the living.
Although starvation cannibalism often accounts for the mutilation of corpses during the Middle Ages, when famines were common, researchers from Historic England and the University of Southampton have found that the ways in which the Wharram Perry remains had been dismembered suggested actions more significant of folk beliefs about preventing the dead from going walkabout.
Their paper, titled A multidisciplinary study of a burnt and mutilated assemblage of human remains from a deserted mediaeval village in England, is published today in the Journal of Archaeological Science — via redwolf.newsvine.com

A group of four birdwatchers from Broome has photographed Australia’s most mysterious bird, the night parrot, in Western Australia.
The sighting is all that more remarkable when you consider that the night parrot was not confirmed as still alive in Australia until three years ago, and that the photograph was taken in a patch of spinifex 2,000 kilometres from where the bird was rediscovered in Western Queensland.
While the group described the parrot as a

The yellow submarine named Boaty McBoatface is set to leave for Antarctica this week on its first science expedition.
The robot is going to map the movement of deep waters that play a critical role in regulating Earth’s climate.
Boaty carries the name that a public poll had suggested be given to the UK’s future £200m polar research vessel.
The government felt this would be inappropriate and directed the humorous moniker go on a submersible instead.
But what many people may not realise is that there is actually more than one Boaty. The name covers a trio of vehicles in the new Autosub Long Range class of underwater robots developed at Southampton’s National Oceanography Centre (NOC).
These machines can all be configured slightly differently depending on the science tasks they are given.
The one that will initiate the
adventures of Boaty will head out of Punta Arenas, Chile, on Friday aboard Britain’s current polar ship, the RRS James Clark Ross.
The JCR will drop the sub into a narrow, jagged, 3,500m-deep gap in an underwater ridge that extends northeast of the Antarctic Peninsula. Referred to as the Orkney Passage, this is the gateway into the Atlantic for much of the

Planet Earth II, possibly the most lavish nature documentary ever made, has catapulted the images taken by fungi photographer Steve Axford from the forest floor to the world.
Axford started photographing rainforests around Lismore, on the NSW North Coast, about 10 years ago, and in retirement the hobby became an obsession.
The next step for Axford was to find a way to create time lapses of his fungi beauties showing the life cycles of the mushrooms.
I had a spare shower which I thought the fungus would grow quite well in so I could bring logs in and put them in the shower and the fungus could grow and I could take time lapse, Axford said.
Well I did that and it worked brilliantly and things have just grown from there.
Time lapse footage of Axford’s fungi photography have gone viral online, and people around the world started to notice that he was discovering plants never seen before.
One of them was a fungus which is now called a blue truffle.
It’s a completely new thing — never seen before — and he’s found that on the forest floor, Dr Tom May from the Herbarium of Victoria said — via redwolf.newsvine.com

A surprising 60-year boom in global octopus, squid and cuttlefish numbers points to long-term changes taking place in the world’s oceans, scientists say.
Research published in Current Biology today shows a steady increase in the world cephalopod population — the class of molluscs comprising octopus, squid and cuttlefish — since the 1950s, at a time of increased fishing, growing pollution and ocean warming.
The data analysis, led by Dr Zoe Doubleday from Australia’s Environment Institute at the University of Adelaide, has confounded previous expectations that cephalopod populations go through cyclical booms and busts.
Anecdotal evidence had suggested the population may experience cyclical booms and busts over time, but there is instead a very consistent increase, she said — via redwolf.newsvine.com

The United Kingdom’s Natural Environment Research Council (NERC) may be regretting their decision to let the public name a polar research ship after the winner of the naming poll was revealed.
The name Boaty McBoatface, which caused an internet sensation during voting, was the runaway winner, beating entries honouring explorers and scientists.
The quirky name put forward for the £200 million ($369 million) Royal Research Ship received 124,109 votes, giving it a staggering lead over runner-up RRS Poppy Mai, named in honour of a young girl with cancer, which received 34,371 votes.
Coming in at third place was RSS Henry Worsley, a tribute to the British explorer. Fourth place was RRS It’s Bloody Cold Here, and RRS David Attenborough also made the top five.
Although Boaty McBoatface received overwhelming public support, the final decision rests with NERC, which may choose to ignore democracy for a less frivolous title — via redwolf.newsvine.com
