What Heroin Addiction Tells Us About Changing Bad Habits

It's a tradition as old as New Year's: making resolutions. We will not smoke, or sojourn with the bucket of mint chocolate chip. In fact, we will resist sweets generally, including the bowl of M&M's that our co-worker has helpfully positioned on the aisle corner of his desk. There will be exercise, …

Cosmigraphics: Picturing Space Through Time in 4,000 Years of Mapping the Universe

Long before Galileo pioneered the telescope, antagonizing the church and unleashing a “hummingbird effect” of innovation, humanity had been busy cataloging the heavens through millennia of imaginative speculative maps of the cosmos. We have always sought to make visible the invisible forces we long …

Electromagnetic waves linked to particle fallout in Earth's atmosphere, study finds

In a new study that sheds light on space weather's impact on Earth, Dartmouth researchers and their colleagues show for the first time that plasma …

What It’ll Take To Put Humans On Mars, Visualized

Last week, NASA successfully flight-tested its new Orion spacecraft, the first step in the project the space agency says will eventually take humans to Mars. The reason for the test was to see how this new spacecraft would hold up in the extreme conditions it would face on a trip to Mars. But, as …

China develops new rocket for manned moon mission

First launch of Long March-9 will take place around 2028, Chinese state media reports<p>China is developing a huge rocket that will be used for its first manned mission to the moon, state media said Monday, underscoring Beijing's increasingly ambitious space programme.<p>The first launch of the Long …

The Kung-Fu Move that Explains One of Quantum Physics' Strangest Properties

Spinors, yet another thing that should not be.<p>As much as that Feynman quote gets tossed around about no one really understanding quantum physics, there are people in the world making laudable strides towards the development of quantum intuition. One of them is the physicist Felix Flicker, who also …

The Navy retrieved Orion from the ocean and is bringing it home to NASA

After its first launch attempt was delayed and eventually aborted last Thursday, NASA's Orion spacecraft finally left Earth on Friday for Exploration Flight Test 1 (EFT-1) before successfully splashing down in the Pacific Ocean. Despite the initial troubles, the capsule — which could eventually …

Colonize A Hyper-Detailed Universe In Virtual Reality

'Elite: Dangerous' is almost too immersive for the goggles it's played on<p>Anyone who's tried on a consumer virtual reality headset in the last two decades knows how far short that technology has fallen from its promise. A good VR device should track head motion and alter the images relayed to each …

Scientists discover a new origin of oxygen on Earth and in space

Scientists have discovered a new way to make molecular oxygen (O2) from carbon dioxide (CO2) -- no green plants involved.<p>Their findings could alter our understanding of the Earth's early atmosphere and how oxygen might form on other planets with carbon dioxide in their atmospheres.<p>In a paper …

A Mathematical Proof That The Universe Could Have Formed Spontaneously From Nothing

Cosmologists assume that natural quantum fluctuations allowed the Big Bang to happen spontaneously. Now they have a mathematical proof<p>One of the …

Experimental Particle Accelerator Boosts Electrons On A Wave

Surf's up at the SLAC National Accelerator Laboratory in California.<p>The SLAC National Accelerator Laboratory's linear accelerator cuts through the grass and trees just west of Stanford University in California, running for two miles, its path clearly visible from the air. Now, in a lab on the same …

How To Stop Light and Make Objects Transparent

New research offers hope for optical cloaking and much more.<p>We see colour in objects because of the way light interacts with them. Different surfaces scatter or emit different wavelengths of light, giving us quantitative colour information in the process. So if colour is, arguably, a matter of …

Two photons strongly coupled by glass fiber

Usually, light waves do not interact with each other. Coupling of photons with other photons is only possible with the help of special materials and …

Do Sunrises Look Different from Sunsets?

You've woken up out of a coma. You yank the IV from your arm and stumble out of the hospital. The sun is perched on the horizon. Can you tell whether …
