But a new study by a team of researchers shows the opposite occurs: Searching to evaluate the truthfulness of false news articles actually increases the probability of believing misinformation. The…

Archaeologists excavate the Offord Cluny 203645 burial. Credit: MOLA Headland Infrastructure Scientists from the Francis Crick Institute, Durham University, and MOLA Headland Infrastructure have discovered that a man who lived between AD 126–228 during the Roman period did not originally come from a rural farmstead near where he was buried, but likely thousands of miles away, possibly outside of the Roman Empire.…

When screening ancient Eurasian individuals for IBD segments, the researchers detected a pair of biological relatives whose remains were buried 1,410 kilometers apart, one in central Mongolia and one in southern Russia.

These almost…

Humanity has always relied on a revolution in materials to advance to the next stage of civilisation. Dutch nanoparticle technology startup VSParticle says it is on the verge of opening up a century’s worth of material innovation in the next 10 years, helping, well, to save the planet.  Co-founder and CEO Aaike van Vugt is convinced that in order to reach our targets of keeping global warming well below 2°C, we need to speed up the process of material development significantly.  “The amount of…

Nano-scale snowflake from Gallium solvent. Credit: Waipapa Taumata Rau, University of AucklandAdventures in Nanotech: Growing a Metallic SnowflakeScientists working at the level of atoms are manipulating metals, opening up possibilities for creating new materials.Working at the level of atoms, scientists in New Zealand and Australia created something unexpected: tiny metallic snowflakes.Why’s that significant? Because coaxing individual atoms to cooperate is leading to a revolution in engineering and technology via…

South Koreans may soon be able to carry a device inside their own bodies in the form of a bespoke tattoo that automatically alerts them to potential health problems, if a science team's project bears fruit. Researchers at the Korea Advanced Institute of Science and Technology (Kaist) in the city of Daejeon southwest of Seoul have developed an electronic tattoo ink made of liquid metal and carbon nanotubes that functions as a bioelectrode. Hooked up to an electrocardiogram (ECG) device or other biosensor, it can send a…
