Open AccessAn antifungal compound secreted by termite workers, phenylacetic acid, inhibits the growth of both termite egg-mimicking fungus and entomopathogenic fungi
Social insects live in closely related family groups but face risks of intrusion and infection by pathogenic and parasitic microbes. To cope with the microbes invading their nests and feeding sites, social ins...

Rapid elimination of symbiotic intestinal protists during the neotenic differentiation in a subterranean termite, Reticulitermes speratus
The symbiosis between lower termites and their intestinal microorganisms, essential for wood digestion, is well characterized. Termites exhibit a reproductive division of labor—kings and queens specialize in r...

Royal presence promotes worker and soldier aggression against non-nestmates in termites
Many eusocial insects can distinguish nestmates from non-nestmate conspecifics, which ensures that altruistic behavior is directed toward close relatives. In termites, however, colonies exhibit various respons...

Open AccessHigh-pressure phase diagrams of FeSe1−xTex: correlation between suppressed nematicity and enhanced superconductivity
The interplay among magnetism, electronic nematicity, and superconductivity is the key issue in strongly correlated materials including iron-based, cuprate, and heavy-fermion superconductors. Magnetic fluctuat...

A non-invasive method for sexing first and second instar larvae of termites using external morphology
Division of labor is fundamental to the ecological success of social insects. In termites, both sexes engage in social tasks, and the sexual division of labor is common in many taxa. Each caste consisting of b...

Preadaptation for asexual queen succession: queen tychoparthenogenesis produces neotenic queens in the termite Reticulitermes okinawanus
Social insects have evolved diverse breeding systems. In the termite species Reticulitermes speratus, queens produce their neotenic replacements parthenogenetically while producing other colony members sexually. ...

Allee effect in termite colony formation: influence of alate density and flight timing on pairing success and survivorship
The Allee effect is a positive relationship between any component of individual fitness and the density of conspecifics. Theoretical models predict that monogamy, where males and females are constrained from h...

Investigation of Novel Te precursor (i-C3H7)2Te for MoTe2 Fabrication
We report the investigation on the properties of a novel Te precursor (i-C3H7)2Te and its effectiveness in fabricating MoTe2. The vapor pressure of the precursor was obtained by measuring the pressure as a functi...

Open AccessDownregulation of the proapoptotic protein MOAP-1 by the UBR5 ubiquitin ligase and its role in ovarian cancer resistance to cisplatin
Evasion of apoptosis allows many cancers to resist chemotherapy. Apoptosis is mediated by the serial activation of caspase family proteins. These proteases are often activated upon the release of cytochrome c fro...
