Collecting phones during college lessons raises grades, large randomized trial finds‎

Your phone vibrates, a notification pops up, or you just take a quick glance at the screen. Even minor interruptions can affect your concentration—not least when you're in class. Now, a large randomized trial involving more than 16,000 students in India shows that teaching without access to mobile phones can improve students' academic performance. The researchers also found that students who experience phone-free teaching firsthand become more supportive of the restrictions. The research is published in Science.

Quantum probability can't be derived without assuming it first‎

For nearly a century, physicists have relied on the Born rule to calculate the chances of different outcomes when they measure a quantum system. Yet despite decades of effort, nobody has managed to derive the rule from more basic mathematical principles without making assumptions about probability along the way.

Scientists discover a promising blood sugar–regulating compound in red alga‎

It is a dietary staple found in sushi, rice wraps and ramen toppings. Commonly known as nori in Japan and gim in Korea, red seaweed is especially popular across Asia. Yet, despite its widespread consumption, many of its nutritional benefits remain poorly understood. Now, research led by Hokkaido University scientists has discovered that digestion of a particular red alga releases a peptide, or a small fragment of protein, with potential benefits for blood glucose control and diabetes prevention. The study was published in Food Bioscience.

Ancient wildfire study offers warning for a warming world‎

New research from the University of Aberdeen has revealed that periods of global warming can trigger long-lasting increases in wildfire activity, with ecosystems taking far longer to recover than previously thought. The study, recently published in Scientific Reports, provides the first detailed evidence of how wildfires responded to a major natural warming event around 65 million years ago, the Danian hyperthermal. This work offers important insights into the risks facing today's world as climate change drives more frequent and severe fires.

Surprising pattern emerges in reincarnation reports‎

An analysis of more than 1,600 cases of purported reincarnation has revealed a striking correlation: The time between death and "rebirth" was shorter on average when records indicated that the prior person had died unexpectedly.
