While police are trying out potential tools, no device currently on the market has been shown to quickly provide a precise measurement of a driver's marijuana intoxication as effectively as a breathalyzer gauges alcohol intoxication

The chemists attach luminescent compounds to tiny gold structures to form biologically safe ‘nanoagents’ that are attracted to calcium-rich surfaces, which appear when bones crack—even at a micro level

To understand how molecules undergo light-driven chemical transformations, scientists need to be able to follow the atoms and electrons within the energized molecule as it rides on the energy "roller coaster"

The new method will help break the stranglehold of carbon-hydrogen bonds present in the chemical feedstocks used to make bioactive molecules

Studies of the neutrinos emitted in the radioactive decay of nuclei held in an ion trap allow sensitive searches for new interactions

As Midwest farmers discuss forming a cooperative to promote aronia, they accept that the crop’s success will depend on marketing

Discovery could make water-splitting reaction cheaper, more efficient

Berkeley Lab scientists directly probe a narrow band where solid and liquid meet, known as the ‘electrochemical double layer’

By tracking the chemicals in "old book smell" and other musuem odors, conservators can react quickly to preserve priceless art and artifacts at the first signs of degradation

Medications can be compromised in many different ways. For example, they may be bulked up with fillers, or they can degrade because they are stored improperly

The technique enables users to measure molecular weights of gaseous samples in the air in real time

"This work is an excellent example of the materials advances possible when we close the feedback loop between first principles calculations and atomic resolution electron microscopy," says researcher
