A Neuroscientist's Radical Theory of How Networks Become Conscious

It’s a question that’s perplexed philosophers for centuries and scientists for decades: Where does consciousness come from? We know it exists, at least in ourselves. But how it arises from chemistry and electricity in our brains is an unsolved mystery.

Earth-sized 'lava world' discovered

A doomed "lava world" with a similar mass and density to that of Earth has been discovered orbiting a star 400 light-years away. Observations suggest the planet, named Kepler 78b, is composed mostly of rock and iron, much like our own planet. But its extremely close proximity to its host star - a hundredth of the distance between the Earth and the Sun - remains something of a puzzle. Details of the work by two teams of researchers appear in Nature journal.

Centuries-old frozen plants revived

Plants that were frozen during the Little Ice Age centuries ago have been observed sprouting new growth, scientists say. Samples of 400-year-old plants known as bryophytes have flourished under laboratory conditions. Researchers say this back-from-the-dead trick has implications for how ecosystems recover from the planets cyclic long periods of ice coverage. The findings appear in Proceedings of the National Academy of Sciences.

Toba super-volcano catastrophe idea 'dismissed'

The idea that humans nearly became extinct 75,000 ago because of a super-volcano eruption is not supported by new data from Africa, scientists say. In the past, it has been proposed that the so-called Toba event plunged the world into a volcanic winter, killing animal and plant life and squeezing our species to a few thousand individuals. An Oxford University-led team examined ancient sediments in Lake Malawi for traces of this climate catastrophe. It could find none.

Saturn hurricane snapped by Cassini craft

An enormous hurricane raging at Saturns north pole has an eye 2,000km (1,250mi) across - big enough to cover the UK 12 times over. The striking images of the storm were snapped from a height of 420.000km (260,000mi) by the Cassini spacecraft, which arrived at Saturn in 2004. They were captured in red and infrared wavelengths and have been false-coloured to show detail. Scientists say the hurricanes winds reach a staggering 150m/s (330mph). But they do not know just how long the sto

Earth's core far hotter than thought

New measurements suggest the Earths inner core is far hotter than prior experiments suggested, putting it at 6,000C - as hot as the Suns surface. The solid iron core is actually crystalline, surrounded by liquid. But the temperature at which that crystal can form had been a subject of long-running debate. Experiments outlined in Science used X-rays to probe tiny samples of iron at extraordinary pressures to examine how the iron crystals form and melt.

How are humans going to become extinct?

An international team of scientists, mathematicians and philosophers at Oxford Universitys Future of Humanity Institute is investigating the biggest dangers. And they argue in a research paper, Existential Risk as a Global Priority, that international policymakers must pay serious attention to the reality of species-obliterating risks. Last year there were more academic papers published on snowboarding than human extinction. The Swedish-born director of the institute, Nick Bostrom, say

Kepler telescope spies 'most Earth-like' worlds to date

The search for a far-off twin of Earth has turned up two of the most intriguing candidates yet. Scientists say these new worlds are the right size and distance from their parent star, so that you might expect to find liquid water on their surface. It is impossible to know for sure. Being 1,200 light-years away, they are beyond detailed inspection by current telescope technology. But researchers tell Science magazine, they are an exciting discovery

Dinosaur-killing space rock 'was a comet'

The space rock that hit Earth 65 million years ago and is widely implicated in the end of the dinosaurs was likely a speeding comet. That is the conclusion of research which suggests the 180km-wide Chicxulub crater in Mexico was carved out by a smaller object than previously thought. Many scientists consider a large and relatively slow moving asteroid to have been the likely culprit. Details were outlined at the 44th Lunar and Planetary Science Conference.

Wave of prawn deaths baffles Chile city of Coronel

Tousands of dead prawns have washed up on a beach in Chile, sparking an investigation. Hundreds of dead crabs were also washed ashore in Coronel city, about 530km (330 miles) from the capital, Santiago. Fishermen suggested the deaths may have been caused by local power stations that use seawater as a cooling agent. The power firms have not commented. Experts are looking into water temperature and oxygen levels and other details to explain the deaths.

Neanderthals' large eyes 'caused their demise'

A study of Neanderthal skulls suggests that they became extinct because they had larger eyes than our species. As a result, more of their brains were devoted to seeing in the long, dark nights in Europe, at the expense of high-level processing. By contrast, the larger frontal brain regions of Homo sapiens led to the fashioning of warmer clothes and the development of larger social networks. The study is published in Proceedings of the Royal Society B.

Fragments of ancient continent buried under Indian Ocean

Fragments of an ancient continent are buried beneath the floor of the Indian Ocean, a study suggests. Researchers have found evidence for a landmass that would have existed between 2,000 and 85 million years ago. The strip of land, which scientists have called Mauritia, eventually fragmented and vanished beneath the waves as the modern world started to take shape. The study is published in the journal Nature Geoscience.

Siberian permafrost thaw warning sparked by cave data

Evidence from Siberian caves suggests that a global temperature rise of 1.5C could see permafrost thaw over a large area of Siberia. A study shows that more than a trillion tonnes of the greenhouse gases CO2 and methane could be released into the atmosphere as a result. An international team has published details in the journal Science.
