Undergrad science and engineering are broadly useful
Although they aren’t researchers, the majority of people who earned bachelor’s degrees in science and engineering at least 10 years ago find their knowledge of those fields useful in their current workplaces. The findings, which come from an analysis of three national databases of college graduates, were reported in August by Mark C. Regets of […]

Compounds pass the smell test
A vile-smelling but versatile class of compounds may find a role in more chemistry laboratories with the introduction of easily made, inoffensive versions. Isonitriles, chemicals characterized by a triple bond between a carbon and a nitrogen atom, are useful in many reactions. But many chemists have shunned them because of their pungency, says Michael C. […]

Forewarning of preeclampsia
Scientists have found an early warning sign of preeclampsia, a pregnancy complication marked by high blood pressure. Pregnant women with too much of a protein called soluble endoglin in their blood have a heightened risk of preeclampsia, the researchers say. Endoglin normally sits on the surface of blood vessels, where it plays a role in […]
