Osteoporosis is associated with vessel diseases attributed to hyperlipidemia, and bone resorption by multinucleated osteoclasts is related to lipid metabolism. In this study, we generated low-density lipoprotein receptor (LDLR)/lectin-like oxidized LDL receptor-1 (LOX-1) double knockout (dKO) mice. We found that, like LDLR single KO (sKO), LDLR/LOX-1 dKO impaired cell-cell fusion of osteoclast-like cells (OCLs). LDLR/LOX-1 dKO and LDLR sKO preosteoclasts exhibited decreased uptake of LDL. The cell surface cholesterol levels of both LDLR/LOX-1 dKO and LDLR sKO osteoclasts were lower than the levels of wild-type OCLs. Additionally, the amount of phosphatidylethanolamine (PE) on the cell surface was attenuated in LDLR/LOX-1 dKO and LDLR sKO pre-OCLs, while the PE distribution in wild-type OCLs was concentrated on the filopodia in contact with neighboring cells. Abrogation of the ATP binding cassette G1 (ABCG1) transporter, which transfers PE to the cell surface, caused decreased PE translocation to the cell surface and subsequent cell-cell fusion. The findings of this study indicate the involvement of a novel cascade (LDLR~ABCG1~PE translocation to cell surface~cell-cell fusion) in multinucleation of OCLs.

The number and diversity of tectonic landforms in our solar system “is truly remarkable,” Watters and Schultz write. Photographs of these structures have stimulated a range of scholarly investigations.

The ecological impacts of micro wind turbines (up to 50 kW) are treated in a diverse way by different local authorities in the UK during the planning approval process, research suggests. The study calls for ecologists, policymakers, planners and industry representatives to improve the integration of ecological information within planning, and for greater guidance for local authorities on the ecological considerations of micro-turbines.

Researchers have demonstrated how the ERICA Integrated Approach can be used to assess the effect of releasing radiation into the environment on local wildlife in a real-world situation. The study applied ERICA to a river in Norway and found that local wildlife was only exposed to low levels of radioactivity from the routine aquatic discharges of a nearby research reactor, although historical exposure was higher.

Drainage tunnels running under roads can provide small animals with safe road crossings, mitigating habitat fragmentation, a new study has confirmed. The researchers suggest that the tunnel design can be further improved to aid animal movements, for example, by providing dry ledges to ensure the routes are still available in times of high rainfall.

Moose avoid roads during day when human activity is highest, new research suggests. Monitoring moose movements in Sweden, researchers have found that the probability of moose being near roads drops after 06:00 and only rises again at approximately 18:00.

Although cities are typically low in biodiversity, they can provide important refuges for native species, new research shows. Urban planning making use of green infrastructure can enhance city habitats and may help reduce the loss of biodiversity that follows urban expansion, the researchers say.

A new disease capable of devastating European salamander and newt populations was probably introduced via international wildlife trade, new research has found. The study shows that the disease is deadly for many European species of salamanders and its analysis of more than 5000 amphibians from across four continents suggests the pathogen spread from Asia to Europe via the pet trade.

Protected areas that allow local people to use the resources in a sustainable way are better for biodiversity conservation than excluding people entirely, a new study suggests. In a review of over 160 scientific studies, the researchers found that protected areas which were managed to allow sustainable access yielded greater socioeconomic benefits. Importantly, those with greater socioeconomic benefits were also more likely to report biodiversity benefits.

Ecological intensification, using land and resources in ways that minimises negative ecosystem impacts while maintaining agricultural productivity, has been proposed as a way to sustainably increase crop yields, but remains under debate due to a lack of evidence. This six-year study of a large commercial farm assessed how using land for wildlife habitat affected food crops. The study shows that it is possible to remove up to 8% of land from production and maintain (and in some cases increase) yield.

Wildlife laws are important to protect animals from harmful human activity, and are largely enforced by state authorities, but occasionally by non-governmental organisations (NGOs). By reviewing academic literature and government legislation, this study explored the different perspectives and ideologies of NGOs and how they enforce wildlife law in practice, focusing on the UK and the US. The study concludes that environmental NGOs are vital for the effective policing of wildlife legislation.

The effects of climate change on the distribution of species can be predicted more accurately by considering the genetic differences between different groups of the same species, a new study suggests. The researchers found that a computer model which incorporated genetic information on different groups of a US tree species was up to 12 times more accurate in predicting tree locations than a non-genetically informed model.

Transport infrastructure is so widespread in Europe that half of the land area is within 1.5 kilometres (km) of paved roads and railway lines, researchers have calculated. The researchers found that in Spain, transport infrastructure has an impact on the abundance of birds in almost half of the country and is affecting the abundance of mammals across almost all of the land area.

Researchers have found that farmer experience, concerns and motivation influence environmental outcomes for agri-environment schemes (AES), in a study in southern England. Farmers with more environmental-management experience and/or concern for wildlife created habitats that provided more pollen and nectar for bees and butterflies and winter seed for birds. The results suggest that supporting environmental learning among farmers may increase the success of AES.

Ecological risk maps showing 'hotspots' of risk to wildlife from single or combined soil pollutants have been developed. These maps can be used to improve risk analysis and stakeholder communications.

New research has provided the first conclusive evidence that microplastics ingested by marine wildlife can transfer toxic pollutants to their tissues. The researchers studied lugworms fed on PVC particles contaminated with either widespread marine pollutants or plastic additives and found that these 'earthworms of the sea' absorbed the chemicals into their gut tissue, which reduced their ability to perform essential functions.

A drug used to treat parasite infections at fish farms can contaminate the surrounding environment and threaten local wildlife, a new study shows. Following a week-long treatment at a Norwegian salmon farm, the authors found concentrations of an anti-sea-lice drug that were high enough to kill some crabs, shrimps and lobsters. However, they suggest the drug is not likely to pose a risk to humans.
