Researchers may have uncovered the reason why some of Earth's earliest animals were commonly preserved as fossils—even though they were essentially fragile "bags of goo"—while later soft-bodied creatu...

University of Massachusetts Amherst's Jeff Podos and his former graduate student João C.T. Menezes have identified two contenders for the title of world's loudest bird: the bare-throated bellbird and ...

Ancient Chinese authorities used many creative ways to punish people, often with methods designed to mark them for life. One brutal example mentioned repeatedly in historical texts is cutting off a pe...

Antarctic krill are tiny shrimp-like creatures that were previously thought to mostly inhabit the upper layer of the Southern Ocean. Although they had occasionally been observed at deeper levels, they...

Quantum mechanics predicts that a vibrating object’s energy comes in discrete packets, yet no measurement of its position reveals this discreteness. Resolving individual energy levels requires a quali...

A Stanford team has documented the first direct observation of quantum jumps of sound in a mechanical resonator, completing an arc of scientific exploration that started more than 100 years ago.

The kine neural reconstruction algorithm produces high-resolution, time-continuous very long baseline interferometry videos, enabling direct measurement of instantaneous plasma velocities and detailed...

Scientists and practitioners are aggressively moving to deploy digital twins—large language model (LLM)-based models of individuals—across social science and policy research. We conducted 19 preregist...

Auroral precipitation expanded equatorward during extreme events Pronounced amplitude scintillations observed even in mid-latitude regions Storm-induced space weather impact produced horizontal ...

On Nov. 11, 2025, Earth experienced a severe geomagnetic storm triggered by solar flares and coronal mass ejections from an active sunspot region. While this kind of storm brings beautiful auroras adm...

In 2022, excavations at a cemetery in Pień, Poland, led by researchers from the Institute of Archaeology at Nicolaus Copernicus University, led to a mysterious discovery. In what they call Grave 75, t...

More than 6,500 years ago, someone carefully drilled a hole in a human tooth, strung it on a cord and likely used it as a necklace. Found during field surveys at the Vinča cultural site of Jablanica i...

Since dark matter is only known to have gravitational interactions, it may plausibly decay to gravitons on cosmological timescales. Although such a scenario can be easily realized, there are currently...

日本いか連合とは イカについてもっとみんなに知ってほしい、そんな思いで活動している組織です。 イカの有する様々な魅力を人々に伝え、興味を持ってもらうことを目的としています。 食材としての魅力はもちろん、日本において見落とされがちな生物としての魅力や、アート面における魅力を、あらゆる手段を用いて広めることを試みています。 日本各地に点在するイカ活動を行う方々をまとめる場、イカに興味を持っている方々....

2026年7月20日、ハーバード大学の数学研究者レヴェント・アルプーゲ博士がXことツイッターに「ヤコビアン予想の反例」を投稿しました。世界の数学研究者に衝撃が走りました。(1/6)

A longstanding open problem asks for an aperiodic monotile, also known as an "einstein": a shape that admits tilings of the plane, but never periodic tilings. We answer this problem for topological di...

The authors artificially realized an aperiodic monotile structure discovered in 2023 and observed chiral optical diffraction. The results reveal distinctive circular-polarization responses from invers...

Discovery of a previously unknown multicomponent alloy formed during the 1945 Hiroshima atomic explosion.

Orcas exhibit highly specialized behavioral and cognitive adaptations that enable them to hunt large marine prey, including the largest teleosts, the sunfish...
