For the first time, a research team from the University of Cologne has observed the electron capture decay of technetium-98, an isotope of the chemical element technetium (Tc). Electron capture decay is a process in which an atomic nucleus "captures" an electron from its inner shell. The electron merges with a proton in the nucleus to form a neutron, turning the element into a different one. The working group from the Nuclear Chemistry department has thus confirmed a decades-old theoretical assumption.

Human health is the Achilles heel of space travel. Researchers at ETH Zurich have now succeeded in printing complex muscle tissue in zero gravity. This will enable drugs for space missions to be tested in the future.

Ballistic electrons are among the most fascinating phenomena in modern quantum materials. Unlike ordinary electrons, they do not scatter off imperfections in the material and therefore travel from A to B with almost no resistance—like a capsule in a pneumatic tube. This behavior often occurs in confined one- or two-dimensional materials.

Researchers from the Hong Kong University of Science and Technology (HKUST) and Tongji University have developed FerroAI, a deep learning model that can produce phase diagrams for ferroelectric materials in just 20 seconds.

European cuckoos lay very different eggs depending on the host species. Genetic analyses have revealed how this adaptation is inherited without leading to speciation.

In recent years, Chinese tissue paper made from bamboo has emerged as a trendy choice for eco-friendly shoppers. However, new research suggests these bamboo paper products may not offer significant climate benefits over tissue produced in the United States and, in some cases, may be more detrimental to the environment.

Land use is at the heart of the many emergencies facing our world today: climate change, biodiversity loss, social injustice and food insecurity. These—exacerbated by unsustainable practices such as industrial agriculture—combine to create simultaneous and interconnected crises.

Hybrid water electrolysers are recent devices, which produce hydrogen or other reduction products at the cathode, while valuable organic oxidation products are formed at the anode. This innovative approach significantly increases the profitability of hydrogen production.

China announced Saturday that its Shenzhou 21 spaceship docked with China's space station with its latest three rotation crew at the country's own record speed after a successful launch.

An explorer and a glaciologist have embarked on a three-month mission to cross part of Antarctica on kite skis in search of ice that is 130,000 years old.
