The study analyzed records of all fish species living on the UK continental shelf. Researchers found that over half contribute to bioturbation through various behaviors, including foraging, burrowing, and nest building. To calculate each species’ bioturbation impact score, the team considered the different ways fish rework sediment, the size of the fish, and the frequency of these activities.
Among the key species identified was the European eel, which burrows into sediment and earned a bioturbation score of 100 out of 125. Critically endangered and primarily caught using traps and fyke nets, the European eel faces climate change, disease, habitat loss, pollution, and fishing threats.
Similarly, the Atlantic cod, a vertical excavator with a bioturbation score 100, is classified as vulnerable. Popularly consumed in dishes like fish and chips, cod populations have declined sharply in regions like the North Sea.
A missing piece of the ocean carbon puzzle
The Convex Seascape Survey, a collaboration between the Blue Marine Foundation, the University of Exeter, and Convex Group Limited, represents the most ambitious effort yet to deepen scientific understanding of the ocean’s role in the Earth’s carbon cycle.
“Anyone who has spent time underwater, whether snorkelling or diving, knows that fish are constantly digging up the seabed,” said author Julie Hawkins.
“It’s hard to believe that such an obvious and important activity has been largely overlooked when it comes to understanding ocean carbon burial.”
“We then calculated polygenic risk scores for each individual.”
The team drew on extensive genetic and retinal data from the UK Biobank, a vast biomedical database that houses information from more than half a million participants.
“You could say that the scale of the UK Biobank’s data has revolutionized biomedical research,” the researcher adds.
The study found that greater genetic susceptibility to schizophrenia is linked to thinner retinal tissue.
However, the effect size is small and becomes apparent only when examined across large populations.
The researchers also highlighted that unlike brain changes, alterations in the retina can be detected easily, non-invasively, and at relatively low cost, offering a notable advantage.
Using optical coherence tomography, a technique similar to ultrasound but for the eye, retinal thickness can be measured in just a few minutes, opening up promising possibilities for early detection and prevention.
“Our study shows the potential of using optical coherence tomography in clinical practice. But large-scale longitudinal studies are needed to examine how useful it will be for prevention,” Rabe said.
Bolivia’s long-dormant ‘zombie’ volcano coming back to life after 250,000 years
Uturuncu volcano in Bolivia hasn’t erupted in over 250,000 years.
High in the Central Andes, a geological enigma lies dormant.
Uturuncu volcano in Bolivia hasn’t erupted in over 250,000 years. It is also known as a “zombie” volcano because it still exhibits unsettling signs of life, like earthquakes and gas emissions.
Previously, the ongoing activity of this seemingly inactive volcano was puzzling, leading scientists to believe the explanation lay in the subsurface movement of magma and gases.
An international collaboration of scientists from China, the UK, and the USA has delved deep into Uturuncu’s inner workings.
The new study combines the power of seismology, sophisticated physics models, and detailed analysis of the volcano’s rock composition.
“Our results show how linked geophysical and geological methods can be used to better understand volcanoes, and the hazards and potential resources they present,” said Professor Mike Kendall, co-author from the Department of Earth Sciences, University of Oxford.
Use of an advanced seismic imaging technique
The volcano’s unrest results in a distinctive “sombrero”-shaped ground deformation. The land above the volcanic system bulges upwards, while the areas around it sink.
Understanding the potential for a real eruption is paramount for the communities living nearby. The stakes are high, with the threat of widespread devastation and loss of life looming.
By meticulously analyzing signals from over 1,700 earthquake events, the team has created high-resolution images of the shallow crust beneath Uturuncu. This technique is known as seismic tomography.
Seismic waves travel at varying speeds through different materials, allowing scientists to map the underground landscape precisely.
Reason behind volcano’s zombie-like behavior
The findings point to an explanation for Uturuncu’s zombie-like behavior.
The unrest isn’t necessarily a prelude to a major eruption. Instead, it appears to be driven by the movement of geothermally heated liquids and gases deposited in reservoirs just beneath the volcano’s crater.
The research team concludes that the movement and accumulation of liquids and gases beneath the crater are the most probable cause of the ground deformation observed at the center of the volcanic system.
The research suggests a low likelihood of an imminent eruption.
Yang and his team followed the natural processes in the leaf of a plant to build the postage stamp-sized device that mimics the way green plants harvest energy from the sun. However, instead of chlorophyll – a natural compound found in green plants that gives them their color and plays a key role in the process of photosynthesis – the scientists used lead halide perovskite photoabsorbers to capture sunlight.
These were paired with finely engineered copper electrocatalysts – designed to resemble tiny flowers – to drive chemical reactions. The electrocatalysts were reportedly inspired by enzymes that regulate photosynthesis in nature. Yang explained how each individual component of a leaf’s photosynthesizing elements had to be carefully replicated and refined.
Building on earlier advances, the scientists successfully triggered an organic oxidation reaction in the photoanode chamber while producing C2 molecules in the photocathode chamber. This achievement resulted in a realistic artificial-leaf architecture, condensed into a device about the size of a postage stamp, that converts CO₂ into C2 molecules using only sunlight.
The team said that the artificial leaf’s ability to produce C2 chemicals may soon lead to precursory ingredients for industries that manufacture essential products, from plastic polymers to fuels for heavy transport like airplanes, which remain difficult to electrify. Yang and his team hope to improve the system’s efficiency and expand the device’s size, moving closer to scaling the technology for practical use.
