Laser Simulations Model Impact of Nuclear Explosions on Asteroids
Researchers constructed miniature asteroids and blasted them with a laser to model the impact of a nuclear explosion on an asteroid threatening to collide with Earth. The research team showed that a brief laser pulse aimed at a miniature replica of an asteroid could produce effects similar to those of a nuclear explosion on an actual space rock.

Laser-Heated Nanowires Produce Microscale Fusion
A dense fusion environment was created by irradiating arrays of nanowires using joule-level pulses from a compact, ultrafast laser. The irradiation of ordered nanowire arrays with femtosecond pulses created ultrahigh energy density plasmas in which deuterons (D) were accelerated up to mega electron volt energies, efficiently driving D–D fusion reactions and ultrafast neutron bursts.

Holographic Waveguide HUD Has Larger Eye Box for Enhanced Display
Researchers demonstrated a functional prototype head-up display (HUD) that uses optical holographic elements to achieve an eye box substantially larger than what is available without the holographic component. Current head-up displays have a small eye box, which can cause the displayed information to partially or wholly disappear from view if users shift their gaze.

Ultrashort Laser Pulses Make Greenhouse Gas Reactive
A highly reactive form of carbon dioxide (CO2), created using ultrashort laser pulses, could help reduce dependence on nonrenewable energy sources. Scientists used a so-called iron complex, whose center contained a positively charged iron atom, to which the constituents of the CO2 were bound multiple times.
