Gigahertz streaking and compression of low-energy electron pulses.

Although radio frequency (RF) technology is routinely employed for controlling high-energy pulses of electrons, corresponding technology has not been developed at beam energies below several kiloelectronvolts. In this work, we demonstrate transverse and longitudinal phase-space manipulation of low-energy electron pulses using RF fields. A millimeter-sized photoelectron gun is combined with synchronized streaking and compression cavities driven at frequencies of and , respectively.

Fungal microbiomes associated with Lycopodiaceae during ecological succession.

Lycopodiaceae species form an early-diverging plant family, characterized by achlorophyllous and subterranean gametophytes that rely on mycorrhizal fungi for their nutrition. Lycopodiaceae often emerge after a disturbance, like in the Hochfeld reserve (Alsace, France) where seven lycopod species appeared on new ski trails following a forest cut. Here, to better understand their ecological dynamic, we conducted a germination experiment of lycopod spores following an anthropogenic disturbance and examined their associated fungi.

Death education for children and young people in public schools.

Conversations about death are often associated with fear, anxiety, avoidance and misunderstandings. Many adults feel that these discussions are inappropriate and confusing for young people. In this project, two fourth-year nursing students partnered with a local palliative care team to examine death education for children.
