Self-disclosure is vital for communication. In the present century, various innovative forms of communication have emerged, including video-conferencing and embodied virtual reality (VR). In this context, researchers from Japan have recently demonstrated that embodied VR, especially with unrealistic avatars, facilitates the revelation of personal feelings. Moreover, female-to-female pairing had the highest self-disclosure score, underlining the role of gender.

A research team at Japan’s National Institutes for Quantum Science and Technology (QST) has demonstrated that electron beam (EB) irradiation can decompose polytetrafluoroethylene (PTFE) — a highly durable plastic known as Teflon — into gaseous components. This method drastically improves the energy efficiency compared to conventional recycling processes, offering a promising path toward reducing the environmental impact from per- and polyfluoroalkyl substances (PFAS).

Recent key advances in chemistry could tackle emissions from the world’s most polluting industries, according to a new study.

A new international study led by Kaunas University of Technology reveals that digital mental health start-ups reaching unicorn status tend to secure private funding early, prioritise simple, scalable services, and use subscription models –  while reliance on state funding may actually hinder growth. The research, based on 125 ventures (including 12 unicorns), suggests success stems from strategic, complementary choices rather than technological complexity alone. Researchers call for a shift in European investment policy to focus more on market relevance and user impact rather than deep tech or rigid scientific criteria.

Scientists at HZB run a long-term experiment on the roof of a building at the Adlershof campus. They expose a wide variety of solar cells to the weather conditions, recording their performance over a period of years. These include perovskite solar cells, a new photovoltaic material offering high efficiency and low manufacturing costs. Dr Carolin Ulbrich and Dr Mark Khenkin evaluated four years of data and presented their findings in Advanced Energy Materials. This is the longest series of measurements on perovskite cells in outdoor use to date. The scientists found that standard perovskite solar cells perform very well during the summer months, even over several years, but decline in efficiency during the darker months.
