Study offers insight into the origin of the genetic code

An analysis of enzymes that load amino acids onto transfer RNAs—an operation at the heart of protein translation—offers new insights into the evolutionary origins of the modern genetic code, researchers report. Their ...

GPS stations can detect clandestine nuclear tests

At the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) meeting this week, American researchers are unveiling a new tool for detecting illegal nuclear explosions: the Earth's global positioning system (GPS).

New discovery is big on nanoscale

Imagine if you could look at a small amount of an unidentified chemical element – less than 100 atoms in size – and know what type of material the element would become in large quantities before you actually saw the larger ...

New forensic method could help police solve crimes

(Phys.org) -- Forensic researchers at Florida International University have developed a groundbreaking method that can tie a shooter to the ammunition used to commit a crime, giving law enforcement agencies a new tool to ...

Random, scattered, and ultra tiny: A spectrometer for the future

Sometimes a little disorder is precisely what's in order. Taking advantage of the sensitive nature of randomly scattered light, Yale University researchers have developed an ultra-compact, low-cost spectrometer with improved ...
