Benefits of acute aerobic exercise on cognitive function: Why do 50% of studies find no connection
Over the past 20 years, many studies have investigated the effects of acute aerobic exercise on cognitive performance. In recent years, meta-analyses 1 of data from these previous research studies have demonstrated that these a single bout of moderate aerobic exercise temporarily improves cognitive performance. However, close examination of the individual research studies on this topic revealed that in approximately 50% of studies, no beneficial link between acute aerobic exercise and cognitive function was found.
An international research collaboration, including Associate Professor KAMIJO Keita (Faculty of Liberal Arts and Sciences, Chukyo University) and Assistant Professor ISHIHARA Toru (Graduate School of Human Development and Environment, Kobe University), conducted an IPD meta-analysis

Parasites manipulate praying mantis’s polarized-light perception, causing it to jump into water
Researchers have revealed that praying mantis (mantids) infected with parasitic hairworms are attracted to horizontally polarized light that is strongly reflected off the surface of water, which causes them to enter the water. In a world-first, these research results demonstrate that parasites can manipulate the host’s specific light perception system to their advantage, causing the host to behave in an abnormal manner.
This discovery was made by an international research group consisting of Graduate student OBAYASHI Nasono, Associate Professor SAKURA Midori and Associate Professor SATO Takuya of Kobe University’s Graduate School of Science, Associate Professor IWATANI Yasushi (Faculty of Science and Technology, Hirosaki University), Professor TAMOTSU Satoshi (KYOUSEI Science Center for Life and Nature, Nara Women’s University) and Dr. CHIU Ming-Chung (National Changhu

15 Basal epithelial cells are a blood–prostate barrier between luminal cells and basement membrane
16 but are absent in prostate carcinoma.
17–19 Loss of basal epithelial cells is a characteristic of prostate carcinoma
20,21 and one of the diagnostic criteria of prostate cancer,
19 suggesting that some essential connections might exist between basal epithelial cells and prostate cancer cells. So, we put out a question regarding whether basal epithelial cells could suppress migration or invasion of prostate cancer cells when basal epithelial cells are artificially added into a cultured system of prostate cancer cells. Through extensive reading of the medical literature, we found that the effects of basal epithelial cells on prostate cancer cells are still limited. One previous study reported that extracellular matrix of basal epithelial cell inhibited the proliferation of prostate cancer cell LNCaP by secreting TGF-β1.
