This Is How the Sun Will Die (in 3D)

The Ring Nebula is one of the most famous celestial objects because of its delicate beauty. That shimmering oval of rainbow colors has popped up everywhere from dorm-room posters to book jackets to album covers to just about every TV backdrop in the history of sci-fi. But it is more than mere eye candy. The Ring is also fascinating for what it tells us about our future.

Middleweight stars like the sun expand and cool in their old age, briefly turning into red giants. After the red giant s

Einstein's 'spooky action' common in large quantum systems

Mathematician have shown that entanglement -- what Einstein termed "spooky action at a distance" -- is actually prevalent in large quantum systems and have identified the threshold at which it occurs.

Just how secure is quantum cryptography?

Unlike classical encryption, quantum communication systems are known to offer the promise of virtually unbreakable encryption. Now, new research on this topic is shaking up the long-held notion that quantum communications are 100 percent secure. Researchers have recently demonstrated that quantum encryption may be susceptible to hacking.

Have health effects from the Chernobyl accident been overestimated?

The impact of the Chernobyl nuclear accident has been seriously overestimated, while unfounded statements presented as scientific facts have been used to strangle the nuclear industry, according to Russian researchers. New research suggests that the health effects of food contamination in particular have been distorted in anti-industry propaganda.
