Some phenomena in our daily lives are so commonplace that we don’t realize there could be some very interesting physics behind them. Take a dripping faucet: why does the continuous stream of water from a faucet eventually break up into individual droplets? A team of physicists studied this question and reached surprising conclusions.
The breakthrough in understanding how a water jet breaks up into droplets was made by a team consisting of Stefan Kooij, Daniel T. A. Jordan, Cees J. M. van Rijn, and Daniel Bonn from the University of Amsterdam (Van der Waals-Zeeman Institute / Institute of Physics), along with Neil M. Ribe from the Université Paris-Saclay. The study is published in the journal Physical Review Letters.
A recent study points to a key bone-strengthening mechanism at work in the body, which could be targeted to treat the bone-weakening disease, osteoporosis.
Led by researchers from the University of Leipzig in Germany and Shandong University in China, the study identified the cell receptor GPR133 (also known as ADGRD1) as being crucial to bone density, via bone-building cells called osteoblasts.
Variations in the GPR133 gene had previously been linked to bone density, leading scientists to turn their attention to the protein it encoded.

Scientists have discovered living microbes producing methane in the fractured rocks deep inside Sweden’s Siljan impact crater, offering insights into Earth’s earliest life and the search for life beyond our planet.
This breakthrough not only sheds light on one of Earth’s most ancient metabolic processes —methanogenesis—but also strengthens the link between meteorite impact structures and microbial survival in extreme environments. The findings are published in the journal mBio.
Methanogenesis is considered one of the earliest metabolisms on Earth, and its presence in deep subsurface environments has long intrigued scientists. Now, for the first time, active microbial methane production has been confirmed in a terrestrial impact crater. Using cultures enriched from fluids 400 meters below the surface, the team demonstrated methane generation from several carbon sources, including indigenous oil.
A warm hand is enough to drive motion in tiny Salmonella-inspired robots that harness molecular-level dynamic bonding.
A team of researchers from China and the U.S. came together to design soft robots with a coordination-motorized oscillator (CoMO) that can make self-sustained micromovements by harvesting small amounts of energy from sunlight or body heat. At the heart of this innovation is a new supramolecular polydimethylsiloxane (PDMS)-based elastic polymer dynamically crosslinked by Eu3+ at the center.
The findings are published in Angewandte Chemie.
