The Download: cattle’s deadly tick-borne disease, and molten salt batteries thumbnail

In the spring of 2021, Cynthia and John Grano, who own a cattle operation in Culpeper County, Virginia, started noticing some of their cows slowing down and acting “spacey.” They figured the animals were suffering from a common infectious disease that causes anemia in cattle. Their veterinarian warned them that a parasite was spreading quickly in the area.

After a third cow died the Granos decided that they would test their blood. The test was positive for the disease, and the Granos were not surprised. The cows died without any treatment.

The Granos aren’t the only cattle owners. This new disease is affecting livestock producers across the US. Even though the disease is rapidly spreading west, researchers aren’t sure how it will develop. If the disease is not controlled in the states, it could cause massive production losses across the country. This could have a significant impact on individual operations as well as the entire industry. Read more .

Super-hot salt could be coming to a battery near you

The world is building more capacity for renewables, especially solar and wind power that come and go with the weather. We need better options for storing our energy in order for renewables to be effective. Batteries are the answer. There are a lot of other chemistries that are slowly entering the energy storage market. Some of these new players may eventually be cheaper than the industry-standard lithium ion batteries. Among the most promising is molten salt technology, which Ambri, a Boston-area startup, is convinced could be up to 50% cheaper over its lifetime than an equivalent lithium-ion system.

But, like other energy storage startups, Ambri faces real obstacles to adoption. Scaling is the biggest hurdle. Read full . story

The big story

Bright LEDs could spell the end of dark skies

A view of Milky Way from the Grand Canyon

August 2022

Scientists have known for years that light pollution is growing and can harm both humans and wildlife. Increased light exposure at night can disrupt sleep cycles, which can lead to cancer and cardiovascular disease. Wildlife suffers from disruptions in their reproductive patterns, increased danger, and loss of stealth.

Policymakers, lighting professionals, and astronomers are all trying to reduce light pollution. Many of them recommend installing light-emitting devices, or LEDs in outdoor fixtures like city streetlights. This is mainly because they can direct light to a specific area. The high initial investment and durability required for modern LEDs means cities must make the right transition or face decades of negative consequences. Read the full story.
