A piece of GSI/FAIR’s cutting-edge research is scheduled to be launched into space next year: the Biophysics department will be involved in one of the next scientific missions on the International Space Station (ISS) with a highly innovative research project. The “HippoBox” project was successfully reviewed by the German Space Agency at DLR and recently selected for participation in the CELLBOX-4 mission on the ISS. The aim of the project is to use brain organoids (“mini-brains”) to investigate neuroplastic changes in a specific area of the brain, the hippocampus – a question that is highly relevant for the medical preparation of future long-term missions in space.

Kyoto, Japan -- Northern fur seals are long-distance migrants, moving seasonally between breeding colonies and wintering grounds. After leaving breeding colonies in autumn, they travel south for winter foraging, returning in early spring. This allows them to avoid sea ice and harsh conditions in northern waters while relocating to ice-free areas.

The southward migration of these seals has been relatively well-documented. One of their primary wintering areas is the Sea of Japan, where they can find abundant prey. They have also been reported to damage fishing gear and remove catch directly from nets, potentially competing with local fisheries.

The seals' northbound migration from wintering grounds back to breeding colonies in spring remains poorly understood, however. Factors such as tag loss, limited battery life, and the difficulty of capturing animals at sea pose particular challenges.

Many animals, including humans, can flexibly modulate their responsiveness to sounds according to different situations. This ability allows them to optimize the use of their limited brain resources by prioritizing the processing of critical information at any given moment. In line with this idea, a research team at Nagoya University in Japan has demonstrated that when female fruit flies are eager to mate, dopaminergic signals can influence their sensitivity to sounds, including courtship sounds from males, which are an essential source of information for species reproduction.

Captive cockatoos have at least 30 different dance moves in their repertoire, including headbanging and body rolls, according to a study by Natasha Lubke at Charles Sturt University in Australia, and colleagues, publishing August 6, 2025 in the open-access journal PLOS One. The moves, of which 17 are newly identified, may be performed with or without music.

Researchers from the University of Pennsylvania found that red blood cells, not just platelets, actively contribute to the contraction of blood clots. This finding challenges long-standing assumptions about clot biology and could lead to new ways of diagnosing and treating clotting disorders, strokes and conditions like thrombocytopenia, where platelet counts are dangerously low.

Study finds changes to El Niño are linked to significant biodiversity loss in multiple types of tropical forest arthropod, including butterflies, beetles and spiders.
