Strange Matter In Remnant Star
The ultradense core of an exploded star contains superfluids, a strange form of superconducting matter which exhibits remarkable properties such as climbing upwards.
The ultradense core of an exploded star contains a bizarre form of superconducting matter called a superfluid, new studies suggest. Superfluids made of charged particles are also superconductors, which allow electric current to flow with no resistance. Superfluidity is a friction-free state of matter, and superfluids created in labs here on Earth exhibit remarkable properties. It can climb upward, for example, and escape airtight containers, researchers said. The matter, found by researchers using NASA's Chandra X-ray Observatory, is at the core of Cassiopeia A, the remains of a massive star that exploded in a supernova.

The rise of anti-scientific thinking and conspiracy is a concerning trend.
- Fifty years later after one of the greatest achievements of mankind, there's a growing number of moon landing deniers. They are part of a larger trend of anti-scientific thinking.
- Climate change, anti-vaccination and other assorted conspiratorial mindsets are a detriment and show a tangible impediment to fostering real progress or societal change.
- All of these separate anti-scientific beliefs share a troubling root of intellectual dishonesty and ignorance.
The history of the Geneva Conventions tells us how the international community draws the line on brutality.
- Henry Dunant's work led to the Red Cross and conventions on treating prisoners humanely.
- Four Geneva Conventions defined the rules for prisoners of war, torture, naval and medical personnel and more.
- Amendments to the agreements reflect the modern world but have not been ratified by all countries.
