More than 1,600 years after the Romans created the famous Lycurgus Cup, a University of Sheffield technician has found a way to reliably reproduce its extraordinary color-changing glass. A glass cup made more than 1,600 years ago has puzzled historians and glassmakers for centuries. When light reflects off its surface, the cup appears jade green. […]
Scientists Discover Something Unexpected 90 Kilometers Beneath Earth
A rock from Papua New Guinea was hotter than expected during its descent into Earth, challenging models of a process that influences earthquakes, volcanoes, and climate. Earth recycles its own surface. In regions called subduction zones, one tectonic plate, a vast slab of Earth’s outer shell, sinks beneath another as the plates collide. These zones […]
Popular Dairy Alternatives Could Be Leaving You Short of Essential Nutrients
A new study reveals that even partially replacing dairy products with plant-based alternatives could significantly reduce the intake of essential nutrients. Replacing even a modest amount of dairy with plant-based alternatives could significantly reduce essential nutrient intake, according to a new study from the University of Surrey. Researchers found that substituting just 20% to 35% […]
A Healthier Form of Salt Could Prevent Nearly 3 Million Deaths Every Year, Scientists Say
A global study spanning 193 countries suggests that a simple change to everyday salt could prevent millions of deaths and cases of cardiovascular and kidney disease each year. Replacing ordinary salt with a potassium-enriched alternative could prevent nearly three million deaths worldwide each year, according to a new study covering 193 countries. Researchers estimate that […]
Scientists Engineer Rice That Fights Back Against a Devastating Crop Disease
An AI-designed gene-editing tool is opening new possibilities for protecting essential food crops. An artificial intelligence-designed gene-editing tool has helped scientists develop rice plants resistant to bacterial blight, a destructive disease that threatens harvests across Asia and Africa. Researchers at the University of Missouri achieved the result using a technology previously tested in animal cells, […]
Deep-Sea Scientists Capture Extraordinary 4K Footage of a Fish With a See-Through Head
MBARI’s first 4K footage of a barreleye fish offers a rare chance to study how its unusual eyes work in the ocean’s dim twilight zone. The day’s deep-sea research was over when a fish with a transparent head came into view. Research Specialist Shannon Johnson spotted it as MBARI’s pilots were “flying” the remotely operated […]

Scientists Find That Older Brains React Very Differently to a Night of Poor Sleep
A single bad night’s sleep may be easier on a healthy older brain than a younger one, though regularly missing sleep still carries risks. Sleep quality often declines with age, yet older adults can seem less affected by a single bad night than younger people. Understanding that apparent mismatch means looking at how the brain […]
