Skid marks left by cars are often analyzed for their impression patterns, but they often don't provide enough information to identify a specific vehicle. UCF Chemistry Associate Professor Matthieu Baudelet and his forensics team at the National Center for Forensic Science, which was established at UCF in 1997, may have just unlocked a new way to collect evidence from those skid marks.

A new study by five doctoral students in neuroscience at the University of Minnesota Medical School calls attention to a lack of regulation and unknown long-term health effects of tear gas. Based on their research, the group recommends changing the protocols around the use of tear gas as a crowd control measure at both the local and national level.

Now that federal funding is flowing again for research on firearm injury prevention, some of the few already-funded researchers doing work in this area share new results and look ahead.

An invention from Purdue University innovators may provide a new option to use directed energy for biomedical and defense applications. The Purdue invention uses composite based nonlinear transmission lines (NLTLs) for a complete high-power microwave system, eliminating the need for multiple auxiliary systems.

Comparison of coda waves, the scattered waves that arrive after the direct waves of a seismic event, can be used to determine the relative locations of two underground explosions, according to a new study published in the open-access journal The Seismic Record.

A Northwestern research team including Professors Justin Notestein and Peter Stair has demonstrated a new approach to chemical catalysis that results in higher yields of propylene -- the basis for many plastics -- using less energy.
