The power of touch in the animal kingdom: Study reveals the role of touch in sustaining friendships and cooperation
Key elements of the caring touch hypothesis. Credit: Trends in Ecology and Evolution (2025). DOI: 10.1016/j.tree.2024.11.017 An international research team led by the University of Constance and Oxford Brookes University has concluded that gentle touch is not only good for your mental health, but also good for developing collaborative relationships. The power of touch and social connections helps people cope…

The power of sunlight: Predicting global lake pollution reduction through photochemistry
Global distribution of 3CDOM* concentrations in lakes. Credit: Eco Environment and Health The research investigates how natural photochemical reactions can help break down emerging pollutants in freshwater systems, with a particular focus on clofibric acid and diclofenac. This study focuses on the contrasting effects of triplet sensitization and direct photolysis and provides new insights into how these processes can reduce…

Bringing the power of tabletop precision lasers for quantum science to the chip scale
Andrei Ishchenko holds an ultra-high-quality ring resonator (left) that helps turn “coarse” light from a commercially available Fabry-Perot laser diode (right) into a low-linewidth laser. Credit: Sonia Fernandez, University of California, Santa Barbara For experiments that require ultra-high precision measurements and control of atoms (think two-photon atomic clocks, cold atom interferometer sensors, quantum gates), more spectrally pure (emitting a single…

Solar wind power likely controls Uranus’ thermosphere temperature
Uranus captured by Webb’s near-infrared camera. Credit: NASA, ESA, CSA, STScI Uranus’ upper atmosphere has been cooling for decades, and now scientists have discovered why. Observations from Earth show that Uranus’ upper atmosphere has been cooling for decades, but there is no clear explanation. Now, a team led by scientists from Imperial College London has determined that unpredictable long-term changes…

Too many children face bullying due to social power imbalances, and educators can prevent this
Credit: CC0 Public Domain Spending time with peers and friends at school is stimulating and positive for many children and adolescents. However, too many children in Canada face the reality of being bullied for certain aspects of themselves. This type of bullying, known as identity-based bullying or prejudice-based bullying, is extremely harmful to children’s sense of belonging at school and…

Nuclear rockets may reach Mars in half the time, but designing the reactors to power them is not easy
Nuclear-powered rockets may one day enable faster space travel. Credit: NASA NASA plans to send a crewed mission to Mars over the next decade, but the 140 million mile (225 million kilometer) journey there could take months or years round trip. This relatively long flight time is a result of the use of conventional chemical rocket fuel. The agency is…
