Laughter may date back 15 million years, shared by humans and great apes
Humans and great apes have been giggling in similar ways since branching off the evolutionary tree, a new study suggests.

Scattered bronze bells in Chinese lord's 2,600-year-old tomb point to ritual deactivation
When archaeologists opened the 2,600-year-old tomb of an ancient Chinese lord, they discovered his magnificent bronze bells had been scattered, their wooden hangings broken. But the most mysterious part of all: This was apparently no accident, with the family of the tomb's owner having chosen to "deactivate" the bells when their powers were no longer needed.

Rare 309-million-year-old fossils suggest early tetrapods developed without tadpole phase
Scientists have long posited that the earliest water animals to transition to land had amphibious tadpole features, going through a metamorphosis akin to that of today's frogs.

Mini monitor measures artificial heartbeat
An international team, including the University of Tokyo, has created a sensor inspired by the lateral line in fish—their "sixth sense" organ—which measures the pulse of lab-grown 3D heart tissue (cardiac organoids). The device, called a biomechanical well plate, looks like a small white box containing four liquid-filled wells.

Wild yeast discovery enables non-GM brewing of ornithine-enriched craft beer
As consumer interest grows in foods and beverages with added nutritional value, brewers are exploring ways to improve fermentation itself rather than relying on post-production additives. Ornithine, a naturally occurring amino acid involved in several biological processes, has attracted attention as a promising ingredient for value-added products. However, increasing ornithine production in brewing yeast is difficult because the metabolic pathway is tightly regulated, making conventional improvement strategies challenging.

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 conducted in a study by the Universidad Carlos III de Madrid (UC3M) demonstrates that the apparent crime gap between the foreign and native populations is primarily due to the fact that the immigrant profile tends to concentrate more young men—the demographic sector with the highest crime rates in any society.

Controlling magnetic chirality could help memory pack in more data
Magnetic storage devices, like a computer's hard disk drive, utilize magnets to represent binary data. However, as these devices are downsized, stray magnetic fields generated by individual magnetic components can interact with neighboring elements to cause operational malfunctions, limiting how much data we can densely pack into memory devices.
