Raman spectroscopy offers a powerful approach to chemical measurement. By directly probing molecular vibrations, it obtains chemical specificity without the need for chemical labels. Thanks to these virtues, it has become ...
A team of geneticists and archaeologists have analyzed the fine-scale genetic structure and ancestry of nearly 1,200 people from the United Arab Emirates (UAE), and found genetic traces of population mixing spanning thousands ...
A new study examining the chemical makeup of iron artifacts from the Viking age aims to uncover new insights into where they came from that could reveal previously unknown information about historic events.
When a space rock survives the turbulent passage through Earth's atmosphere and strikes the surface, it generates shockwaves that can compress and transform minerals in the planet's crust. Since these changes depend on the ...
An international team including researchers from the University of Bern and the University of Geneva as well as the National Centre of Competence in Research (NCCR) PlanetS analyzed the atmosphere of one of the most extreme ...
Pharmaceutical researchers speak of a hit when they come across a promising substance with a desired effect in early drug discovery. Unfortunately, hits are rarely bull's-eyes, often showing undesirable side effects that ...
For humans, background noise is generally just a minor irritant. But for quantum computers, which are very sensitive, it can be a death knell for computations. And because "noise" for a quantum computer increases as the computer ...
A team of Agricultural Research Service (ARS) and university scientists has developed an electronic nose to sniff out whitefly infestations of tomato plants.
Scientists using the Atacama Large Millimeter/submillimeter Array (ALMA) and the Karl G. Jansky Very Large Array (VLA) made a rare detection of a likely stellar flyby event in the Z Canis Majoris (Z CMa) star system. An intruder ...
The age of the oldest fossils in eastern Africa widely recognized as representing our species, Homo sapiens, has long been uncertain. Now, dating of a massive volcanic eruption in Ethiopia reveals they are much older than ...
