Although not as well-known as carbon dioxide or methane, nitrous oxide is a significant greenhouse gas. One of its primary sources is the application of nitrogen-based fertilizers on farm fields. Yet measuring the levels of nitrous oxide in a field is difficult because today’s sensors are heavy and consume large amounts of power.
Medicines that travel directly to a tumor or other target in the body hold great promise for the treatment of cancer and other diseases. Targeted medications have the potential to be highly effective at reduced doses, dramatically reducing side effects for the patient and improving quality of life.
When Tsvetelina (Lina) Churalska and Sarah Nagy teamed up with two other Princeton students to build an energy drink business, they quickly realized that the process was going to be more difficult than they had anticipated.
Three domestically available raw materials — coal, biomass and natural gas — may reduce the country’s dependence on imports and vulnerability to volatile oil prices while addressing the increasing national fuel demand at a low financial and environmental cost.
Yeast, bacteria and mammalian cells are often harnessed to act as small factories that produce drugs, biofuels and other products.
Measuring magnetism is important in applications ranging from the detection of landmines to the diagnosis of health conditions, such as epilepsy and cardiac arrhythmias, caused by disruptions in electrical signals.
Researchers in fields ranging from toxicology to marine biology will be pleased to know that a new microscope is in development — one that produces high-quality 3-D images by observing subjects as they flow through a liquid channel beneath the microscope’s lens.
As atmospheric carbon dioxide levels rise, Liquid Light Inc., a startup of 26 people located in Monmouth Junction, N.J., sees opportunity in carbon dioxide emissions.
