Distributed Compact Plasma Reactor Sterilization for Planetary Protection in Space Missions

This study demonstrates the effectiveness of the Active Plasma Sterilizer (APS) in achieving log reductions of pathogenic bacteria on various materials using cold plasma technology.

FLOCK STASIS DRIVES FLYING SPEED IN PIGEONS, WHILE ARTIFICIAL MASS ADDITIONS DO NOT

This study shows that flock stasis, not artificial mass additions, increases flying speed in pigeons, highlighting the role of phenotypic group composition in flight dynamics.

Homing pigeon (Columba livia) dominance hierarchies are stable over time and resistant to perturbation

This study examines dominance hierarchies in homing pigeons, finding they are stable over time and resistant to physiological perturbations.

Number and proportion of P. falciparum gametocytes vary from acute infection to chronic parasite carriage despite unaltered sexual commitment rate

The paper compares gametocyte levels and sexual commitment in P. falciparum infections during dry and wet seasons, finding increased mature gametocytes in asymptomatic dry season carriers without changes in sexual commitment.

Pre-winter fattening and fat loss during wing moult: the annual cycle of fat deposition in captive barnacle geese (branta leucopsis)

This study investigates fat deposition and loss in captive barnacle geese during wing moult and pre-winter fattening, finding significant fat reduction during moult and peak fat storage in late-September to early-October.

The determinants of aggression in male Siamese fighting fish, Betta splendens

This study investigates the factors influencing aggression in male Siamese fighting fish, finding that color, body mass, and personality traits like neophobia affect aggressive behavior.

Overall dynamic body acceleration as an indicator of dominance in homing pigeons

The paper uses accelerometry to measure energy expenditure in homing pigeons and finds that dominant birds have higher movement but no linear correlation between rank and energy expenditure.

Mechanics Of Flight Feathers: Effects Of Captivity?

The paper compares flight feather stiffness and size between wild and captive Barnacle Geese and feathers dropped versus regrown during moult, finding wild feathers are stiffer despite long-distance migration.

Plasmodium falciparum-specific IgM B cells dominate in children, expand with malaria and produce parasite inhibitory IgM

The paper identifies Pf-specific IgM B cells in children, showing they expand during malaria and produce inhibitory IgM antibodies.
