New technique yields fast results in drug, biomedical testing

A new technique makes it possible to quickly detect the presence of drugs or to monitor certain medical conditions using only a single drop of blood or urine, representing a potential tool for clinicians and law enforcement.

How does soil store CO2?

Global CO2 emissions continue to rise—in 2012 alone, 35.7 billion tons of this greenhouse gas entered the atmosphere. Some of it is absorbed by the oceans, plants and soil. They provide a significant reservoir of carbon. ...

Better Way to Measure Particle Shape Proves Popular

Tiny particles are pivotal to climate change, public health, and nanotechnology. A significant fraction of these particles are aspherical, yet scientists must routinely assume the particles are spherical to interpret many ...

Nanopores make portable mass spectrometer for peptides a reality

University of Groningen scientists have developed nanopores to directly measure the mass of peptides. Although the resolution needs improvement, this proof of principle shows that a cheap and portable peptide mass spectrometer ...

Discovery of 100 fatty acids opens new research paths

Fatty acids are the molecular building blocks that form the lipids essential for life. While some lipids form cell membranes, others are present naturally as triglycerides in body fat and the waxes on our hair and skin.

Scientists trace particulate air pollution to its source

(Phys.org)—Scientists at the University of California, Davis, have, for the first time, developed a system that can determine which types of air particles that pollute the atmosphere are the most prevalent and most toxic.
