Religion And Health: Is There A Link?

From ABC News:

Just Changing Churches May Be Harmful to Your Health, Study Claims.

Many scientific studies in recent years have sought to prove a link between religion and health, and they usually ended up contending that faith may be very good medicine. But new research attempts to look at the opposite side of that coin: What happens when a person loses faith, or even switches from one religious group to another?

Decision Needed On European Space Truck Upgrade

ARV would have a conical re-entry capsule and a more capable service module

From The BBC:

European countries will soon be asked if they wish to press on with design work to upgrade the ATV space truck.

The robotic craft takes supplies to the International Space station (ISS), but could be enhanced to return cargo to Earth and even carry a human crew.

Further feasibility work will cost some 150m euros, and nations are likely to decide by the end of the year whether to continue or shelve the project.

Much may depend on how they view future plans for human space exploration.

From Scientific American:

Genetic traces of an ancient hepatitis B-like virus confounds common knowledge about viral evolution.

Viruses can be thought of as hyperspeed shape-shifters, organisms that can adapt quickly to overcome barriers to infection. But recent research has been finding ancient traces of many viruses in animal genomes, DNA insertions that have likely been there for much longer than the viruses were previously thought to have existed at all.

The Difference Engine: Bigger Than Wi-Fi

From The Economist:

HAVE you ever wondered, if you are of an age with your correspondent, about those missing channels on old television sets? Apart from channel two, the rest of the original VHF channels on the dial were usually just the odd numbers from three to 13. That was because, in over-the-air VHF broadcasting, the channel between two analogue stations had to be left unused so that it would not interfere with adjacent ones. When UHF broadcasting came along, empty “guard bands” were added to each channel for the same reason. In some places, this so-called “white space” of unused frequencies separating working channels amounted to as much as 70% of the total bandwidth available for television broadcasting.

Humankind has seen the Stone Age, the Golden Age, and the Iron Age. Some would argue the 20th century should be called the Silicon Age. Based on the events of its first 10 years, the 21st century may very well become known as the Carbon Age.

An important tension is unfolding between two types of carbon--atmospheric carbon in the form of carbon dioxide emissions, and elemental carbon as a building block for a new generation of devices designed to manage and abate those same pollutants.

Mars Moon Phobos Likely Forged By Catastrophic Blast

From Space.com:

One of the two moons of Mars most likely formed from rubble catapulted into space after a comet or meteorite slammed into the Red Planet, a new study finds.

The moon, Phobos, looks a lot like an asteroid: It's lumpy, potato-shaped and very small. It has an average radius of just 11 kilometers (6.8 miles).

Scientists have long wondered about the origin of Phobos — is it merely a captured asteroid, the leftovers from Mars' formation or evidence of a cosmic Martian hit-and-run with another object?

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.

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.

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.

From The Daily Mail:

Scientists have developed a computer chip that could pave the way for a new generation of powerful 'quantum' computers.

The photonic chip, built by scientists from Bristol’s Centre for Quantum Photonics, uses light rather than electricity to pass information.

The breakthrough could lead to 'quantum' computers capable of performing complex calculations and simulations that are impossible for today's computers.

Aurora Saturnalis: Halos At The Poles Of The Ringed Planet

From New Scientist:

Saturn was already the solar system's undisputed lord of the rings. Now newly processed images from the Cassini spacecraft are revealing previously unseen halos of infrared auroral light above the planet's poles.

Auroras on Saturn form like those on Earth, when charged particles in the solar wind stream down the planet's magnetic field towards its poles, where they excite gas in the upper atmosphere to glow. Some auroras on the ringed planet are also triggered when some of its moons, which are electrically conducting, move through the charged gas surrounding Saturn.
