Publisher of the K-Ah demographic study
A volcano off southern Japan erupted 7,300 years ago, burying the archipelago in ash and killing many of the hunter-gatherers living nearby. New statistical modeling of radiocarbon dates shows the human toll was sharply uneven: some regions emptied, others declined hundreds of kilometers away, and communities in northern Kyushu kept growing.

Published the study
Scientists have watched a tectonic plate off Vancouver Island tearing itself apart. The Juan de Fuca plate, sliding beneath North America along the Cascadia subduction zone, is fragmenting piece by piece rather than failing all at once.

Published the study on September 16, 2026
A Tyrannosaurus rex ran a body temperature of about 97 degrees Fahrenheit in life, nearly identical to a modern human. Chemists extracted the figure from rare isotope bonds preserved in fossilized tooth enamel — the first direct temperature measurement of the dinosaur.

Published the Chariklo ring evolution study in September 2026
Chariklo is a small body orbiting between Saturn and Uranus, and it hosts two narrow rings discovered in 2013. New James Webb Space Telescope observations show those rings are not stable: the inner ring has grown denser while the outer ring has faded, all within a few years.

Published the research
For more than a century, diamond was classified as nonpiezoelectric — its perfect cubic lattice symmetry meant that squeezing it produced no electrical charge. A team led by the University of Hong Kong just showed that polycrystalline diamond membranes only a few micrometers thick generate a measurable voltage when bent, with a piezoelectric voltage coefficient of 82.2 millivolt-meters per newton, higher than many conventional piezoelectric materials.
Two sets of remains from the Indonesian island of Sulawesi carry teeth worn into deep, rounded grooves and traces of betel nut residue in their dental tissue. One individual lived 25,000 to 16,000 years ago; the other 7,600 to 6,300 years ago.

Published the nanolaser research
A Danish research team has built a nanolaser small enough that thousands could fit on a single microchip. It traps light in a space far smaller than previous designs and runs at room temperature on very little energy.
