How an effort to reduce fossil fuel use led to another environmental problem: Light pollution

Credit: Unsplash/CC0 Public Domain In 2014, Los Angeles cut its annual carbon emissions by 43% and saved $9 million in energy costs by replacing the bulbs in more than half of the city’s street lamps with light-emitting diodes. That year, the Nobel Prize in physics went to three scientists whose work made those LEDs possible. … Read more

Study outlines steps to reduce ‘cybervetting’ bias in hiring

Credit: Pixabay/CC0 Public Domain A new paper on cybervetting says that organizations need to develop and implement clearly defined rules regarding how they use online information about job candidates. Failing to better regulate their use of cybervetting can introduce bias into an organization’s hiring processes, invade the privacy of job seekers and ultimately hurt the … Read more

Researchers working to reduce space junk threat, impact

New research points to increasing pollution in the upper atmosphere due to reentering satellites, rocket bodies and other incoming spaceflight flotsam. That troublesome trend is leading researchers to come up with mitigation proposals, one of which would use fabrication concepts to reduce the size of space debris pieces that make it to Earth. The Aerospace … Read more

Burying short sections of power lines would drastically reduce hurricanes’ future impact on coastal residents

Climate change could make heat waves a dangerous hazard of future hurricanes. Credit: US Navy / Mass Communication Specialist 1st Class R. Jason Brunson / Released As Earth warms due to climate change, people living near the coasts not only face a higher risk of major hurricanes, but are also more likely to experience a … Read more

How year-round crops could reduce farm pollution in the Mississippi River

Credit: Pixabay/CC0 Public Domain Don Wyse’s field of winter barley used to be mostly empty in the spring. Eight years ago, just a tenth of the grain would survive the winter in this experimental field at St. Paul. But this year, after repeatedly refining the plant’s genetics, the field was flush with swaying, pale yellow … Read more

Limiting global warming to 1.5 degrees Celsius would reduce risks to humans by up to 85%

The study calculates reductions in human exposure to a … Read more

School-based intervention aims to reduce behavioral health impact for LGBTQ+ youth

Credit: Unsplash/CC0 Public Domain An estimated 83% of the 20 million LGBTQ+ people in the United States have experienced abuse or significant adverse childhood experiences (ACE) that have significantly impacted their mental health as adults compared to their heteronormative peers. This is associated with significantly higher rates of depression, anxiety, substance abuse and suicidal ideation … Read more

Can farms produce to the max and still reduce greenhouse gas emissions?

Credit: Unsplash/CC0 Public Domain Decarbonizing agriculture is critical for the US to reach net zero emissions by 2050. A new data-driven approach looks at practices that are good for the earth and profitable for farmers. The world relies on American farmers to do much more than set its tables. In addition to producing food for … Read more

Giving metal to microbes could reduce greenhouse gas

Marsh wetland at Argonne National Laboratory. Credit: Jeffrey Catalano Like you and me, microbes need some metals in their diet to stay healthy. The metals help the microbes fully “digest” food. After a good meal, the microbes that gain energy by chemically reducing nitrate release a harmless byproduct: nitrogen, the gas that makes up 78% … Read more
