Study says strong political action needed to reduce increasing share of millionaires' enormous environmental impact

The number of millionaires in the world is steadily increasing, and their emission patterns make it difficult, if not impossible, to meet the Paris Agreement's target of limiting global warming to 1.5 degrees Celsius. According to a new study by tourism professor Stefan Gössling, the millionaires will, within just a few decades, be responsible for almost three quarters of carbon dioxide...

Plant protection of the future may come from the plants themselves

Humans and animals all have chemical and microbial signatures that influence their well-being in one way or another. In medicine, the use of probiotics rather than antibiotics has become high on the agenda. However, humans and animals are not the only ones who have a close relationship with their microflora. Plants exhibit similar relationships with their environments too. Just as they do in...

One facility makes a big contribution to Salt Lake's winter brown cloud

The 2.4 million people who live along Utah's Wasatch Front experience some of the most severe winter particulate matter air pollution in the nation. Now, analysis of measurements taken during National Oceanic and Atmospheric Administration (NOAA) research flights in 2017 indicates that emissions from a single source, a magnesium refinery, may be responsible for a significant fraction of the fine...

Lucy spacecraft set to encounter new asteroid target

NASA's Lucy spacecraft will add another asteroid encounter to its 4-billion-mile journey. On Nov. 1, 2023, the Southwest Research Institute-led Lucy mission will get a close-up view of a small main belt asteroid to conduct an engineering test of the spacecraft's innovative asteroid-tracking navigation system.

New shield blocks electromagnetic interference while allowing wireless optical signals

Researchers have experimentally demonstrated, for the first time, a mechanically flexible silver mesh that is visibly transparent, allows high-quality infrared wireless optical communication and efficiently shields electromagnetic interference in the X band portion of the microwave radio region. Optical communication channels are important to the operation of many devices and are often used for...

Keep on flowing: The importance of freshwater corridors in the Amazon

The Amazon rainforest and basin are crucial for the balance of the Earth's environmental systems that enable life as we know it. The world's largest rainforest covers 6.7 million square kilometers and encompasses the largest network of forests and rivers in the world, housing around 10% of the world's biodiversity and 20% of the planet's freshwater.

Fraudulent microchip use and compliance issues found on controversial lion farms in the Free State, South Africa

A number of serious management and compliance issues were revealed on lion farms in the Free State province, South Africa, by a joint team of researchers from MONITOR, Blood Lions, and World Animal Protection. Potentially fraudulent activities relating to the use of microchips, operating without valid permits, and incomplete, inconsistent, and unclear record keeping were some of the irregularities...

Citizen scientists discover more than 1,000 new burial mounds

Over the past few years, citizen scientists from the Heritage Quest project have scoured the entire Veluwe and Utrechtse Heuvelrug areas for unknown archaeological heritage. One of the results of this research is that the number of known burial mounds in this area has doubled.

Can we increase the carbon content of agricultural soils?

Climate change is considered one of the most pressing problems of our time. In this context, soil plays a greater role than might be expected. Soil can simultaneously store CO2 from the atmosphere and emit CO2 through microbial decomposition of organic matter.

Field trial shows that knowing the carbon footprint of food prompts people to eat more sustainably

Labeling the carbon footprint of food prompts people to eat more sustainably: This was the key finding for TRR 266 Accounting for Transparency researchers from LMU Munich, HU Berlin and Aalto University in Finland in a recent field trial. How the information is presented turned out to be the critical factor: The effect was greatest when CO2 information was visualized as traffic light colors or...
