Increase in forest fires may damage the crucial ozone layer

All particles that reach the atmosphere cause different chemical reactions. Particles come partly from natural sources such as volcanic eruptions and forest fires, and partly from pollution and emissions. Aerosol researcher ...

Improving crystal engineering with DNA

Northwestern investigators have demonstrated that fine-tuning DNA interaction strength can improve colloidal crystal engineering to enhance their use in creating an array of functional nanomaterials, according to a recent ...

New purification method could make protein drugs cheaper

One of the most expensive steps in manufacturing protein drugs such as antibodies or insulin is the purification step: isolating the protein from the bioreactor used to produce it. This step can account for up to half of ...

New modeling approach helps advance cryopreservation

Cryopreserving tissues and organs without damaging them requires a delicate dance through the principles of thermodynamics. Carnegie Mellon University's Biothermal Technology Laboratory has a novel modeling approach for isochoric ...

Studying clouds can provide deeper insight into climate change

An international team of scientists conducted CALISHTO, a large-scale air measurement campaign in Greece last fall, with the goal of surveying, counting and characterizing the tiny particles and their impact on cloud formation. ...
