From Live Science:

NEW YORK — Among colored diamonds, red is particularly rare, and mysterious, since no one knows for certain the origin of the color within the stone.

One of the three known red diamonds weighing more than 5 carats (1 gram), an emerald-cut stone about the size of a small fingertip rests against a gray background in an American Museum of Natural History display case. This stone, known as the Kazanjian Red Diamond, has a dark hue resembling that of a garnet or a ruby, and in its nearly century-long history, it has been mistaken for the latter.

From The BBC:

One-fifth of the world's plants - the foundation of life on Earth - are at risk of extinction, a study concludes.

Researchers have sampled almost 4,000 species, and conclude that 22% should be classified as "threatened" - the same alarming rate as for mammals.

A further 33% of species were too poorly understood to be assessed.

The analysis comes from the Royal Botanic Gardens at Kew, the Natural History Museum and International Union for the Conservation of Nature (IUCN).

From Popular Science:

The universe has only about 3.7 billion years in which to settle its affairs. At least, that’s the new assertion from a group of physicists who say that there is a 50 percent chance that time will end within that time frame. If the laws of physics as we understand them are in fact correct, then time must eventually end – and their math shows that both the sun and the Earth should still be around when that happens.

Deceptive Robots Hint At Machine Self-Awareness



From New Scientist:

A robot that tricks its opponent in a game of hide and seek is a step towards machines that can intuit our thoughts, intentions and feelings

ROVIO the robotic car is creating a decoy. It trundles forward and knocks over a marker pen stood on its end. The pen is positioned along the path to a hiding place - but Rovio doesn't hide there. It sneaks away and conceals itself elsewhere.

When a second Rovio arrives, it sees the felled pen and assumes that its prey must have passed this way. It rolls onwards, but is soon disappointed.

The End Of An Era In British Military Aviation


Last flight? The Cold War Vulcan bomber may not take to the skies again, unless its owners can raise £400,000 by the end of October

Last Vulcan Flies Into The Unknown: Iconic Cold War Plane Will Be Grounded Unless Owners Can Raise £400,000 -- The Daily Mail

Soaring into the sky with its engines booming, this may be the mighty Cold War Vulcan bomber making its last flight.

The former RAF bomber, the last airworthy plane of its type, is shown at an airshow at Coventry Airport in aid of the Help for Heroes military charity at the weekend.

But the plane - which was in active service from 1960 to 1984 and is one of the greatest achievements of British aerospace-engineering - will not be able to fly again unless its owners raise £400,000 by the end of October for costly maintenance to ensure it passes safety tests.

Geology In A War Zone

The Treasure of the Safit Chir -- Popular Science

For over two centuries we have struggled to understand the scope of Afghanistan's mineral wealth. Now geologists, if they can determine what lies beneath the nation's ground, might also help bring stability to the surface.

Early one morning in June, just a week after the New York Times reported claims by U.S. officials that Afghanistan was perched atop enough copper, gold, iron, lithium, and assorted rare minerals and gemstones “to fundamentally alter the Afghan economy and perhaps the Afghan war itself,” I made my way with a local guide to the illegal mines of the Safit Chir, an emerald-rich line of ridges 100 miles northeast of Kabul. After a three-hour climb up trails navigable only on foot or by donkey, we greeted several miners, and one of them led us past the dark maws of the tunnels to the edge of a ridge, the better to see the places where his nation’s wealth might be hidden.

Large Hadron Collider Signal 'May Show Big Bang Conditions'

The "high multiplicity collision" signal picked up by the Compact Muon Solenoid detector at the Large Hadron Collider. Photo: CERN

From The Telegraph:

A never-before-seen signal in a collision at the Large Hadron Collider has raised hopes that the giant particle accelerator is on the verge of serious breakthroughs.

A series of high-energy proton-proton collisions observed at the Compact Muon Solenoid (CMS) detector led to 100 or more charged particles being produced. These so-called "high multiplicity" collisions were unusual in that the resulting particles are "correlated" - associated with each other at the moment of their creation. One interpretation of the results is that the protons are being forced together at such high energies that the quarks that form them are released, becoming a free-flowing fluid of quarks and gluons like that which existed immediately after the big bang.

Mankind's First Genocide?

New Discoveries Hint At 5,500 Year Old Fratricide At Hamoukar, Syria -- The Independent

Five years ago, archaeologists found the “earliest evidence for large scale organized warfare in the Mesopotamian world.” Using slings and clay bullets a – likely Uruk – army took over the city of Hamoukar, burning it down in the process. Now, new discoveries at a nearby settlement shed more light on the 3500 BC battle – and raise more questions. If the invading army was from Uruk, did they kill their own people? If so, why?

Hamoukar is a city that flourished in northern Syria since at least 4000 BC. They traded in obsidian and in later times copper working became increasingly important to the city’s economy. Thousands of clay sealings – once used to lock doors or containers and impressed with stamp seals – were found at the ancient site. They tell of a bureaucratic system that was almost as complex as our own.
