The increase in atmospheric CO2 levels, attributed primarily to human activities such as the burning of fossil fuels and land-use changes, is often discussed in the context of its role in driving climate change and its associated impacts. In fact, the mission statement of the IPCC explicitly states their focus on climate change risk.…

A very, very old mammoth tusk found near a road-widening project, for State Route 54 near National City in the early 1990s, set off considerable controversy among scientists. When a group of archeology, paleontology, and geology specialists authored an article in the journal Nature in 2017 arguing proof of human existence in the Americas…

Two ancient clay tablets from in Iraq and carved from top to bottom with cuneiform script contain traces of a “lost” language that bears remarkable similarities to ancient Hebrew. Archaeologists have deciphered two ancient clay tablets believed to date back around 4,000 years in Iraq. The clay tablets are carved with cuneiform…

After scientists created oxygen-28 in the lab, it almost immediately degraded, baffling physicists around the world For the first time, scientists have created oxygen-28, a rare oxygen isotope that has 12 more neutrons than oxygen-16, the most common form of oxygen on the planet. This newly created “heavy” oxygen isotope has the…

Solar radiation modification is a form of geoengineering that aims to cool off the Earth by reflecting sunlight back into space. The controversial strategy comes with significant risks, but that didn't stop the White House from moving forward with a research plan for “solar and other rapid climate interventions.” SRM is a form of…

When I was in secondary school, a teacher showed me an animated optical illusion in which a dancer appears to be spinning in one direction. I was adamant that the dancer was spinning clockwise, while my teacher insisted it was spinning counterclockwise. She then told me that you could change the direction of the dancer by focusing on the…

Imperial physicists have recreated the famous double-slit experiment, which showed light behaving as particles and a wave, in time rather than space. The experiment relies on materials that can change their optical properties in fractions of a second, which could be used in new technologies or to explore fundamental questions in…

There is an inspiring story hidden behind the formulas and word problems of single-variable calculus – a story that should be told in every introductory calculus course, but usually isn’t. Regardless of if you’ve taken a few calculus courses before or are just beginning your study of calculus, the following video aims to give a…
