A new study has revealed how even the deepest seafloors are affected by the daily back-and-forth of the tides, and the change of the seasons, and that currents at the bottom of the ocean are far more complicated than previously thought. These findings are helping us understand the deep-sea pathways...
Recent volcanic ‘fires’ in Iceland triggered by storage and melting in crust
Scientists have detected geochemical signatures of magma pooling and melting beneath the subsurface during the 'Fagradalsfjall Fires', that began on Iceland's Reykjanes peninsula in 2021. Samples show that the start of the eruption began with massive pooling of magma, contrasting initial hypothesis for magma ascent straight from the mantle.
Green hydrogen: ‘Artificial leaf’ becomes better under pressure
Hydrogen can be produced via the electrolytic splitting of water. One option here is the use of photoelectrodes that convert sunlight into voltage for electrolysis in so called photoelectrochemical cells (PEC cells). A research team has now shown that the efficiency of PEC cells can be significantly increased under pressure.
More electricity from the sun
A coating of solar cells with special organic molecules could pave the way for a new generation of solar panels. This coating can increase the efficiency of monolithic tandem cells made of silicon and perovskite while lowering their cost -- because they are produced from industrial, microstructured, standard silicon wafers.
Genes or environment? A new model for understanding disease risk factors
Researchers have developed a model that more accurately predicts how genetics and air pollution levels causally influence disease development.
Scientists using new sound tech to save animals from extinction
Scientists are using new technology to help endangered animals by listening to their sounds.
Injury dressings in first-aid kits provide a new technique to reveal shark species after bite incidents
Scientists have revealed that injury dressings found in first-aid kits can reliably be used to identify shark species involved in bite incidents by deploying medical gauze to gather DNA samples from aquatic equipment, such as surfboards.
Super-black wood can improve telescopes, optical devices and consumer goods
Thanks to an accidental discovery, researchers have created a new super-black material that absorbs almost all light, opening potential applications in fine jewelry, solar cells and precision optical devices.
Winter breeding offers lifeline for monarch butterflies in Northern California
Monarch butterflies in Northern California are adapting to a changing climate by embracing an unexpected strategy: breeding in the winter. The shift could be key to the survival of the iconic insect, according to a new study.
NASA data shows July 22, 2024 was Earth’s hottest day on record
July 22, 2024, was the hottest day on record, according to a NASA analysis of global daily temperature data. July 21 and 23 of this year also exceeded the previous daily record, set in July 2023. These record-breaking temperatures are part of a long-term warming trend driven by human activities,...
