Bees spew water at their hive-mates when the temperature rises

When honeybee hives get too hot, thirsty bees beg their specialised, water-foraging sisters for more liquid, which ends up cooling the colony.  Honeybees have a few strategies for chilling out: some fan the nest, others leave the hive to increase air flow, and a few zip off looking for ponds or puddles. These “water collector” bees fill their bellies with water, fly back home, then regurgitate the liquid. Other bees slurp it up and spit it out around the hive, allowing the colony to cool as the water evaporates.

Hobbit discovery: 700,000-year-old find could shed new light on evolution

A 700,000-year-old hobbit has been discovered on the Indonesian island of Flores, shedding new light on human evolution.  The dwarf-like ancient relative of modern man stood just one metre tall and has been dated at half a million years older than a hobbit found on the island a decade ago.  The researchers argue their fossil find descended from Homo erectus, which would suggest an incredible case of evolutionary reversal where human bodies — including brains — actually shrunk.

Blogger Comment:

The simplest explanation is that the "hobbits" are Australopithecines.  The material evidence is consistent with this and inconsistent with both Homo habilis and Homo erectus.  The view that they were later species that "shrunk" is not the simplest theory, and the proposition that smaller primate brains would be more adaptive than larger brains is exceedingly unlikely and needs plausible supporting argument.  There are many examples of other primates (orang utans, gibbons, japanese macaques) migrating enormous distances from their place of speciation.

New DNA technology confirms Aboriginal people as first Australians

A new look at ancient bones with the latest DNA technology has confirmed Aboriginal Australians as the continent's first people. Researchers say the findings overturn a 2001 paper that argued the oldest known Australian human remains found near Lake Mungo in New South Wales were from an extinct lineage of modern humans that occupied the continent before Aboriginal Australians.

Dark radiation may be causing universe to expand faster than expected

The universe is expanding 5 to 9 per cent faster than expected and scientists speculate the finding may be explained by a mysterious force called dark radiation.

Mars is at the tail-end of an ice age that would have seen large swathes of the dusty red planet covered with ice.

Neanderthals built mystery underground circles 175,000 years ago

Archæological evidence now suggests Neanderthals were capable of symbolic thought, had a basic knowledge of chemistry, medicine and cooking, and perhaps some capacity for speech. They may even have taught modern humans new artisanal skills when the two species met and interbred.

A reassessment of evidence from Bruniquel cave, near Toulouse in south-west France, suggests even more Neanderthal sophistication. In one chamber, 336 metres from the cave entrance, are enigmatic structures – including a ring 7 metres across – built from stalagmites snapped from the cave floor.

Monkey seen caring for dying mate then grieving after she dies

The alpha male of a group of snub-nosed monkeys and his dying partner spent a final, tender hour together beneath the tree from which she had fallen minutes earlier, cracking her head on a rock. Before she succumbed, he gently touched and groomed her. And after she was dead he remained by her side for 5 minutes, touching her and pulling gently at her hand, as if to try and revive her.

Trees observed resting branches while ‘asleep’

For the first time, trees have been shown to undergo physical changes at night that can be likened to sleep, or at least to day-night cycles that have been observed experimentally in smaller plants.  Branches of birch trees have now been seen drooping by as much as 10 centimetres at the tips towards the end of the night.

Newborn babies do not imitate us.  It is a skill they have to learn — likely by us imitating them, rather than the other way around.

World's oldest known ground-edge stone axe fragments found in Western Australia

A fragment of the world's oldest known ground-edge axe has been found in the remote Kimberley region of northern Australia. The discovery pushes back the technological advance to between 45,000 to 49,000 years ago, and coincides with the arrival of people in Australia. The fragment is 10,000 years older than the previous oldest known fragments found in northern Australia in 2010.

Ancient bubbles in Pilbara rock show Earth had thin atmosphere 2.7b years ago

Air bubbles trapped in 2.7 billion-year-old lava flows in the Pilbara suggest the Earth's atmosphere weighed less than half that of today and was far thinner than previously thought. The discovery has forced a rethink of how the Earth managed to stay relatively ice-free during that period, despite the Sun being much cooler than it is today.

Evidence that early humans in North Africa were eaten by other animals

A large carnivore — most likely a hyena — ate an ancient human 500,000 years ago, according to the discovery of teeth marks on a thighbone found in a Moroccan cave. The fossilised femur provides the first definitive evidence that carnivores ate early humans in North Africa during the Middle Pleistocene era.

Three planets discovered orbiting nearby cool small star TRAPPIST-1

Astronomers have discovered three planets orbiting the habitable zone of an ultra-cool dwarf star just 40 light-years from Earth. The discovery is the first evidence supporting the hypothesis that these very low-mass and low-temperature stars should have Earth-sized or smaller planets orbiting them.

Adult-like proportions may have given baby titanosaurs an advantage when they hatched

Unlike some types of dinosaurs that were reliant on their parents after they hatched, the offspring of the world's largest vertebrates to have ever walked the Earth were probably independent soon after birth.

Monster black hole 3 billion times the mass of the sun formed by trio of colliding galaxies

Three colliding spiral galaxies 1.8 billion light years from Earth have produced a monster black hole weighing in at 3 billion times the mass of the Sun.

Oldest ever human genome sequence may rewrite human history

The oldest ever human nuclear DNA to be reconstructed and sequenced reveals Neanderthals in the making – and the need for a possible rewrite of our own origins.  The 430,000-year-old DNA comes from mysterious early human fossils found in Spain’s Sima de los Huesos, or “pit of bones”.

Insects may have had basic 'consciousness' more than 500 million years ago

Recent neuro-imaging suggests insects are fully hardwired for both consciousness and egocentric behaviour, providing strong evidence that organisms from flies to fleas exhibit both. Consciousness comes in many levels, and insects have the capacity for at least one basic form: subjective experience.
