Testicular macrophages are guardians of fertility

Two types of testicular macrophages have been identified, one found in interstitial spaces and another on the surface of seminiferous tubules. These macrophages prevent other immune system agents from entering the testes by releasing specific molecules.

Chemical profile of ants adapts rapidly

Researchers found that ant species with closely related genetic backgrounds can have significantly different chemical profiles, which can change faster than other traits during evolution. Climate also influences the composition of these profiles, with species from humid regions having distinct hydrocarbon patterns.

Massive particles test standard quantum theory

Scientists at the University of Vienna and Tel Aviv have conducted the first experiment testing standard quantum theory with massive molecules, placing upper bounds on higher-order interference. The researchers used a nanofabricated mask to create a diffraction pattern that followed expectations of standard quantum mechanics.
