Phys.org / An iconic spear-throwing device likely wasn't used by prehistoric hunters until around 10,000 years ago
Archaeologists have long pictured prehistoric hunters taking down mammoths and other megafauna using the atlatl, a handheld spear-throwing device that uses leverage to achieve greater velocity and force when throwing darts. ...
Phys.org / Cosmic neutrino 'whispers' may surface in 5,000-day Super-Kamiokande signal
Neutrinos: They have no electric charge, pass through matter like a ghost and are so light they were initially thought to have zero mass. These are just some of the traits that make them so difficult to detect. Research on ...
Phys.org / Spain data on 5.5 million convictions challenges immigration-crime link
When analyzing crime, the foreign population typically shows higher rates than the native population. However, crime statistics change significantly when comparing groups of the same age and gender. A detailed data analysis ...
