Iron Age plant remains tell new agricultural story in east Africa
Archeologists can tell quite a bit about ancient human life from plant fossils–dietary preferences, farming techniques, and even which sports were popular. Now, an international team of researchers found 2,300-year-old plant remains that are the earliest known evidence of plant farming in east Africa. These old flora are described in a study published July 10 in the journal Proceedings of the Royal Society B and indicate that various crops were likely introduced to the area over time.
‘Bacterial glitter’ shimmers without pigments
Despite their mostly microscopic stature, bacteria are a pretty big deal in nature. They can help forests regrow after fires, influence the health of much larger organisms, and live in intricate colonies that resemble a tie dye shirt. Some bacteria can even reflect light and give off the appearance of color without using pigments the way that most colorful objects in nature do. To find out how this quality works on a genetic level, an international team of researchers designed an experiment and used an artificial intelligence model to study the mechanisms behind it. They found some important ecological connections that are detailed in a study recently published in the journal Proceedings of the National Academy of Sciences (PNAS). The findings could lead to more environmentally friendly dyes inspired by nature.
Taking a train during a heat wave? Watch out for ‘sun kinks’
This story was originally published by Grist. Sign up for Grist’s weekly newsletter here. One of the iconic sensory experiences of riding a train is actually the sound of ingenuity. As steel railroad tracks heat up, they grow: 1,800 feet of rail expands by more than an inch for every 10 degrees Fahrenheit of temperature increase. So rails used to be laid down in sections — each between 30 and 60 feet long — with small gaps.

When the ocean got hot, the sharks bulked up
A giant spike in ocean temperatures about 93 million years ago may have helped sharks grow from stubby bottom dwellers into bigger predators. This surge in ocean heat in the Cretaceous period came from a gush of volcanic lava that sent carbon dioxide levels skyrocketing. This created a greenhouse effect that raised ocean temperatures. In response, some shark species evolved elongated pectoral fins that helped make them faster and move to a different part of the water column in order to eat. The findings are described in a study published last month in the journal Current Biology.

One fish, two fish, 3,000 fish …
This article was originally featured on Knowable Magazine. It was pure serendipity. I had been searching for a suitable pet for my son for months when I spotted a young teenager — let’s call him Matovu — who’d strategically placed himself and several fishbowls near the entrance of one of the many shopping arcades in Uganda’s capital. Speaking in broken English, Matovu told me that the Kampala Capital City Authority frequently detains unlicensed hawkers and confiscates their goods. At this very moment, the coast was clear.
