AFRICAN PENGUINS FOLLOW THE GAZE DIRECTION OF CONSPECIFICS

African penguins follow the gaze direction of conspecifics

Gaze following is widespread among animals.However, the corresponding ultimate functions may vary substantially.Thus, it is important to study previously understudied (or less studied) species to develop a better understanding of the ecological contexts that foster certain cognitive traits.Penguins (Family Spheniscidae), despite their wide interspe

High prevalence of Schistosoma japonicum and Fasciola gigantica in bovines from Northern Samar, the Philippines.

The cause of zoonotic schistosomiasis in the Philippines is Schistosoma japonicum, which infects up to 46 mammalian hosts, including humans and bovines.In China, water buffaloes have been identified as major reservoir hosts for schistosomiasis japonica, contributing up to 75% of human transmission.In the Philippines, water buffaloes (carabao; Bubal

Genetic variation within native populations of endemic silkmoth Antheraea assamensis (Helfer) from Northeast India indicates need for in situ conservation.

A.assamensis is a phytophagous Lepidoptera from Northeast India reared on host trees of Lauraceae family for its characteristic cocoon silk.Source of these cocoons are domesticated farm stocks that crash frequently and/or wild insect populations that provide new cultures.The need to reduce dependence on wild populations for cocoons necessitates ass

Paradoxical effects of posterior intralaminar thalamic calretinin neurons on hippocampal seizure via distinct downstream circuits

Summary: Epilepsy is a circuit-level brain disorder characterized by hyperexcitatory seizures with unclear mechanisms.Here, we investigated the causal roles of calretinin (CR) neurons in the posterior intralaminar thalamic nucleus (PIL) in hippocampal seizures.Using c-fos mapping and calcium fiber photometry, we found that PIL CR neurons were activ
