Geoscientists have a good idea of how earthquakes happen. The Earth’s crust — which is on average 22 miles deep — is broken into continental and oceanic plates that rub against one another other due to the movement of molten rock in the Earth’s mantle. Over the decades and centuries, pressure builds at the points where the tectonic plates converge, until the plates crack and the pressure is released, sending shockwaves in all directions. On the moon, however, things aren't quite the same ...read more
When Italy’s national soccer team took on the Soviet Union in the semi-finals of the European Championship in 1968, the score was 0-0 at the end of the game and a further period of extra time failed to separate the two sides.

Depending on the heart rate your doctor measures during your annual checkup, you might get a stamp of approval — or a raised eyebrow and questions about your overall health.But a new study confirms that a normal resting heart rate isn't the same for everyone. Data from over 92,000 FitBit-wearers were analyzed in a new PLOS ONE paper, showing that average resting heart rates ranged between 40 and 109 beats per minute (BPM). Though not all of those rates are necessarily healthy, the study did fi ...read more
Apollo 7 sent a trio of astronauts into space in 1968, making it the first successful crewed NASA mission. But about 15 hours into the flight, astronaut Wally Schirra began developing the symptoms of a bad head cold, with the rest of his team following suit. Balancing a fog of symptoms, including sniffles and congestion, on top of their heavy workload was a recipe for misery. Considering the extensive training and screening astronauts go through to ensure they’re in optimal health for missions ...read more
