Erupting Bardarbunga Volcano In Iceland Sits On A Massive Magma Hot Spot

Science2.0 - 5 hours 32 min ago

 Massive amounts of erupting lava have connected with the fall of civilizations, the destruction of supercontinents and dramatic changes in climate and ecosystems. 

Since August 31st, Bárðarbunga volcano in central Iceland has been spewing spectacular amounts of lava. A new paper finds that high mantle temperatures miles beneath the Earth's surface are essential for generating such large amounts of magma - and  Bárðarbunga volcano lies directly above the hottest portion of the North Atlantic mantle plume.

Ebola's Evolutionary Roots Are Ancient

Science2.0 - 5 hours 32 min ago

Though Ebola tends to occur in waves, the filoviruses family to which Ebola and its lethal relative Marburg belong, are at least 16 million years old.

Filoviruses likely existed in the Miocene Epoch, and at that time, the evolutionary lines leading to Ebola and Marburg had already diverged, according to a paper inl PeerJ. It was once believed that the viruses only came into being some 10,000 years ago, coinciding with the rise of agriculture but now it is believed to have developed at the time when great apes arose.

Genetically Modified Stem Cells Kill Brain Tumors

Science2.0 - 6 hours 8 min ago

There may soon be a new way to use stem cells in the fight against brain cancer. A team has created a way to genetically engineer stem cells so that they can produce and secrete tumor-killing toxins that eradicate cancer cells remaining in mouse brains after their main tumor has been removed.

The stem cells are placed at the site encapsulated in a biodegradable gel. This method solves the delivery issue that probably led to the failure of recent clinical trials aimed at delivering purified cancer-killing toxins into patients' brains.

Preventing Murder: 3 Ways To Predict Who Will Become A Killer

Science2.0 - 6 hours 24 min ago


Right now, the police can't do much to help you until after a crime has been committed. In a science-fiction tale about free will and psychological determinism, Philip K. Dick's "Minority Report" detailed a world where PreCrime officers stop acts before they happen. They know who is going to do it.

But psychic mutants are a simplistic convention, criminologists have instead been trying to do it in the real world.

Smart Aquaculture Outsmarts Climate Change

Science2.0 - 6 hours 32 min ago

El Niño is nothing new for fishers. Long before it was being used as evidence of climate change, fisheries management experts knew they would have to adjust, just like they will have to adjust this year.

A new study shows how smart fisheries management overcame expected detrimental effects of coral reef fisheries impacted by the 1997/98 El Niño.

When a human bone was found on a gravelly riverbank by a bone-carver who was searching for mammoth ivory, little did he know it would provide the oldest modern-human genome yet sequenced.

The anatomically modern male thigh-bone, found near the town of Ust’-Ishim in south-western Siberia, has been radiocarbon-dated to around 45,000 years old.
