New archaeology method could confirm Bible event Thermal demagnetization, a new method used on mud bricks that are thousands of years old, may help archaeologists understand information preserved in burned material. The technique could reveal how building materials were made, and the authors of the study say in this case it corroborates the Bible’s description […]

Sensors are essential tools for detecting and analysing trace molecules in a variety of fields, including environmental monitoring, food safety, and public health. However, developing sensors with high enough sensitivity to detect these tiny amounts of molecules remains a challenge. One promising approach is surface-enhanced infrared absorption (SEIRA), which uses plasmonic nanostructures to amplify the […]

Octopus DNA helps scientists resolve geological mystery Scientists analyzed the genetic history of an octopus species living in the Antarctic to confirm a theory about when the West Antarctic ice sheet last collapsed. The Turquet’s octopus has different populations separated by the West Antarctic ice shelves today, but the creature’s family tree indicates that the […]

Morning people may have inherited Neanderthal genes People’s predisposition to wake up early may be linked to inherited genetic variants from Neanderthals, who lived at high latitudes in Europe and Asia and evolved to cope with seasonal variation in daylight.

Human beings first disturbed moon dust on Sept. 13, 1959, when the USSR’s unmanned spacecraft Luna 2 alighted on the lunar surface. In the following decades, more than a hundred other spacecraft have touched the moon — both crewed and uncrewed, sometimes landing and sometimes crashing. The most famous of these were NASA’s Apollo Lunar […]

Warming waters may release methane “fire-ice” Methane hydrate, or fire-ice, frozen underneath the ocean floor can thaw and release methane into the atmosphere as the climate warms. Researchers used 3D seismic imaging techniques to examine a portion of fire-ice off the coast of Mauritania and discovered that some dislodged methane moved from a hydrate stability […]

The detection, identification, and analysis of macromolecules is needed in many areas of life sciences, including protein research, diagnostics, and analytics. Mass spectrometry is often used as a detection system for proteins – a method that typically separates charged particles (ions) according to their mass-to-charge-ratio and measures the intensity of the signals generated by a […]

Dinosaurs may have influenced evolution of human aging The genetic foundations of the human aging process may have evolved from the pressure that dinosaurs put on mammals 100 million years ago. “While humans are among the longest-living animals, there are many reptiles and other animals that have a much slower aging process and show minimal […]
