The takedown: a deadly tick-borne disease on cattle and molten salt batteries


This is today’s edition of The Download, our weekday newsletter that provides a daily dose of what’s happening in the tech world.

New tick-borne disease kills US cattle

In the spring of 2021, Cynthia and John Grano, who own a cattle farm in Culpeper County, Virginia, began noticing that some of their cows were slowing down and acting “spacey.” They believe the animals are suffering from a common infectious disease that causes anemia in cattle. But their veterinarian warned them that another parasite-borne disease was spreading rapidly in the area.

After a third cow died, the Granos decided to test her blood. Sure enough, the test came back positive for the disease: theileria. And with no treatment available, cows continued to die.

Livestock owners like the Granos are not alone. U.S. livestock producers are facing this new and unknown disease without much information. Researchers do not yet know how theileria will develop, although it is rapidly spreading westward in the country. If states cannot bring the disease under control, then national production losses from sick cows can significantly harm both individual operations and the industry as a whole. Read the full story.

Super hot salt can reach a battery near you

The world is building more capacity for renewables, especially solar and wind, which come and go with time. But for renewables to make a real difference, we need better energy storage capabilities. This is where batteries come into play. And for convenience, there’s a wave of alternative chemicals slowly making inroads into the growing energy storage market.

Some of these new players could end up being cheaper (and in various ways better) than industry-standard lithium-ion batteries. Among the most promising is molten salt technology, which Ambri, a Boston startup, believes could be up to 50 percent cheaper over its lifetime than an equivalent lithium-ion system.

But like its rivals experimenting with other forms of energy storage, Ambri faces real barriers to adoption, with scaling the main, ever-present obstacle. Read the full story.

The big story

Bright LEDs could mean the end of dark skies

View of the Milky Way from the Grand Canyon

August 2022

Scientists have known for years that light pollution is increasing and can harm both people and wildlife. In humans, increased exposure to light at night disrupts sleep cycles and is linked to cancer and cardiovascular disease, while wildlife suffers from disrupted reproductive patterns, increased danger and loss of stealth.

Astronomers, politicians and lighting experts are working to find ways to reduce light pollution. Many are advocating the installation of light-emitting diodes in outdoor lighting fixtures such as urban street lights, mainly because of their ability to direct light to a targeted area. But the high initial investment and durability of modern LEDs means cities must get the transition right the first time or face decades of consequences. Read the full story.
