Superfluids are supposed to flow indefinitely. Physicists just watched one stop moving

Ordinary matter, when cooled, transitions from a gas into a liquid. Cool it further still, and it freezes into a solid. Quantum matter, however, can behave very differently. In the early 20th century, researchers discovered that when helium is cooled, it transitions from a seemingly ordinary gas into a so-called superfluid. Superfluids flow without losing […]

New ABF crystal delivers high-performance vacuum ultraviolet nonlinear optical conversion

Vacuum ultraviolet (VUV, 100–200 nm) light sources are indispensable for advanced spectroscopy, quantum research, and semiconductor lithography. Although second harmonic generation (SHG) using nonlinear optical (NLO) crystals is one of the simplest and most efficient methods for generating VUV light, the scarcity of suitable NLO crystals has long been a bottleneck.

Could an increase in Antarctic ice levels trigger a new ice age and help reverse global warming?

Scientists studying the causes of ice ages say that an increase in Antarctic ice levels could be enough to trigger a new ice age that would reverse the current warming of our planet.

As climate change continues to cause rising global temperatures that are busy melting the ice caps, scientists are racing to figure […]

Was this underwater pyramid in China constructed before the Great Flood?

There is always an ongoing dispute about how old the ancient pyramids really are. Mainstream archaeologists tend to follow an agreed-upon timeline, while others continuously question the dates. Could the Egyptian pyramids really date back hundreds of thousands of years, as some suggest?

One thing is clear: The debate may never end. However, if […]

Ponce de Leon’s enemies linked him to ‘Fountain of Youth’ myth, inadvertently making him immortal

Juan Ponce de Leon is probably best known for discovering what is now known as the U.S. state of Florida, but he’s also associated with a search for the so-called “Fountain of Youth” which would supposedly make one young again if they so much as bathed in or drank from the water.

But as […]
