Putting Einstein to the Test
Physicists have developed an experiment involving super cold matter and an empty elevator shaft that will test one concept crucial to Einstein's Theory of General Relativity.
Physicists have developed an experiment involving super cold matter and an empty elevator shaft that will test one concept crucial to Einstein's Theory of General Relativity. The experiment may shed light onto the tension between quantum physics and Einstein's relativity. "Einstein's 'equivalence principle', which underpins general relativity, says that if you stand in a falling elevator, your acceleration should effectively cancel out the pull of gravity, leaving you unable to determine whether you are in free fall or whether there is simply no gravity present at all," says the New Scientist. "Determining whether quantum systems are also subject to this equivalence principle might help pin down why quantum theory has so far resisted any merger with general relativity – a mystery that haunts physics."

A new study explores how certain personality traits affect individuals' attitudes on obesity in others.
- The study compared personality traits and obesity views among more than 3,000 mothers.
- The results showed that the personality traits neuroticism and extraversion are linked to more negative views and behaviors related to obesity.
- People who scored high in conscientiousness are more likely to experience "fat phobia.
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.
