Stone Age "megastructure" under Baltic Sea sheds light on strategy used by Paleolithic hunters over 10,000 years ago
Archaeologists have identified what may be Europe's oldest human-made megastructure, submerged 21 meters below the Baltic Sea in the Bay of Mecklenburg, Germany. This structure—which has been named the Blinkerwall—is a continuous low wall made fr.....»»
Once melting glaciers shut down the Gulf Stream, we will see extreme climate change within decades, study shows
Superstorms, abrupt climate shifts and New York City frozen in ice. That's how the blockbuster Hollywood movie "The Day After Tomorrow" depicted an abrupt shutdown of the Atlantic Ocean's circulation and the catastrophic consequences......»»
5,000 atoms are all you need: The smallest solid-state ferroelectricity
Recent research has broken the size limitation of traditional ferroelectric effects, providing experimental evidence and theoretical simulations to confirm that a structure with as few as 5,000 atoms can still exhibit solid-state ferroelectric effect.....»»
Scientists identify genetic mechanism responsible for plant leaf diversity
Plant leaves come in many different shapes, sizes and complexities. Some leaves are large and smooth, while others are smaller and serrated. Some leaves grow in single pieces while others form multiple leaflets. These variations in leaf structure pla.....»»

Cathedral termite mounds inspire lunar structure design
NASA has big plans for its Artemis program—to return Americans to the moon for the first time since 1972 and establish a lunar base for humans by the end of the decade......»»
New insights in the regulation of genetic information exchange
Within every cell in our body, our DNA is tightly bundled with proteins to form structures known as chromosomes. The commonly known shape of a chromosome relates to an X-shaped appearance in many organisms. The formation of the X-shaped chromosome re.....»»
Astronomy observation instrument used to uncover internal structure of atomic nuclei
A group of researchers has used equipment originally intended for astronomy observation to capture transformations in the nuclear structure of atomic nuclei, reports a new study in Scientific Reports......»»
Desert ants: Earth"s magnetic field calibrates their navigation system
They are only a few centimeters tall and their brains have a comparatively simple structure with less than 1 million neurons. Nevertheless, desert ants of the Cataglyphis genus possess abilities that distinguish them from many other creatures: The an.....»»
Archaeologists discover oldest known bead in the Americas
University of Wyoming archaeology Professor Todd Surovell and his team of collaborators have discovered a tube-shaped bead made of bone that is about 12,940 years old. The bead, found at the La Prele Mammoth site in Converse County, is the oldest kno.....»»
Sensors made from "frozen smoke" can detect toxic formaldehyde in homes and offices
Researchers have developed a sensor made from "frozen smoke" that uses artificial intelligence techniques to detect formaldehyde in real time at concentrations as low as eight parts per billion, far beyond the sensitivity of most indoor air quality s.....»»

Helium droplets capture double water structure
An elusive structure involving two water molecules, which had been predicted but never observed, has been isolated by RIKEN chemists. This finding could have implications for a wide range of fields ranging from astrochemistry to corrosion of metals......»»
Ice ages were not as dry as we thought, according to surprising new Australian cave study
During ice ages, dry, frozen terrain extended over much of northern Europe, Asia and North America. Many plants and animals retreated from these desolate, harsh landscapes and sought refuge in pockets of more hospitable territory......»»
