Land use linked to water quality and quantity      (via sciencedaily.com)     Original source 

Researchers recently published a study that focuses on the Sudbury-Assabet and Concord watershed in eastern Massachusetts, and which links hydrological changes, including floods, drought and runoff, to changing patterns of land use.

Metal-filtering sponge removes lead from water      (via sciencedaily.com)     Original source 

Engineers have developed a new sponge that can remove metals -- including toxic heavy metals like lead and critical metals like cobalt -- from contaminated water, leaving safe, drinkable water behind. In proof-of-concept experiments, the researchers tested their new sponge on a highly contaminated sample of tap water, containing more than 1 part per million of lead. With one use, the sponge filtered lead to below detectable levels.

Global warming puts whales in the Southern Ocean on a diet      (via sciencedaily.com)     Original source 

In the autumn, when right whales swim towards the coasts of South Africa, they ought to be fat and stuffed full. But in recent years, they have become thinner because their food is disappearing with the melting sea ice.

Hammerhead sharks hold their breath on deep water hunts to stay warm      (via sciencedaily.com)     Original source 

Scalloped hammerhead sharks hold their breath to keep their bodies warm during deep dives into cold water where they hunt prey such as deep sea squids. This discovery provides important new insights into the physiology and ecology of a species that serves as an important link between the deep and shallow water habitats.

Paper refutes assertion that effects of bottom trawling on blue carbon can be compared to that of global air travel      (via sciencedaily.com)     Original source 

A new paper refutes previous findings on the amount of CO2 released from the seabed by bottom trawling. The previous paper made significant headlines around the world on release in 2021, as it equated the carbon released by bottom trawling to be of a similar magnitude to the CO2 created by the global airline industry.

Dark clouds on the horizon      (via sciencedaily.com)     Original source 

Our industrialized society releases many and various pollutants into the world. Combustion in particular produces aerosol mass including black carbon. Although this only accounts for a few percent of aerosol particles, black carbon is especially problematic due to its ability to absorb heat and impede the heat reflection capabilities of surfaces such as snow. So, it's essential to know how black carbon interacts with sunlight. Researchers have quantified the refractive index of black carbon to the most accurate degree yet which might impact climate models.

How life and geology worked together to forge Earth's nutrient rich crust      (via sciencedaily.com)     Original source 

Around 500 million years ago life in the oceans rapidly diversified. In the blink of an eye -- at least in geological terms -- life transformed from simple, soft-bodied creatures to complex multicellular organisms with shells and skeletons. Now, research has shown that the diversification of life at this time also led to a drastic change in the chemistry of Earth's crust -- the uppermost layer we walk on and, crucially, the layer which provides many of the nutrients essential to life.

Unlocking the power of photosynthesis for clean energy production      (via sciencedaily.com)     Original source 

Researchers are embarking on a groundbreaking project to mimic the natural process of photosynthesis using bacteria to deliver electrons to a nanocrystal semiconductor photocatalyst. By leveraging the unique properties of microorganisms and nanomaterials, the system has the potential to replace current approaches that derive hydrogen from fossil fuels, revolutionizing the way hydrogen fuel is produced and unlocking a powerful source of renewable energy.

African rhinos share retroviruses not found in Asian rhinos or other related species      (via sciencedaily.com)     Original source 

Rhinoceros belong to a mammalian order called odd-toed ungulates that also include horses and tapirs. They are found in Africa and Asia. Until recently, evidence suggested that throughout their evolutionary history, gamma-retroviruses such as Murine leukemia virus had not colonized their genomes, unlike most other mammalian orders. The colonization process is called retroviral endogenization and has resulted in most mammalian genomes being comprised of up to ten percent retroviral like sequences.

Researchers discovered that various species share a similar mechanism of molecular response to nanoparticles      (via sciencedaily.com)     Original source 

Living organisms are exposed to nanoparticles through different products and air pollution every day. After examining hundreds of exposures, researchers revealed how various species share a specific epigenetic molecular response to particulate matter. They have now explained the mechanism through which cells and organisms adapt to long-term exposures to nano-sized materials.
