Published How a drought led to the rise of skateboarding in 1970s California
(via sciencedaily.com) Original source Why did professional skateboarding arise in southern California in the 1970s? Was it a coincidence, or was it a perfect storm of multiple factors? It's fairly well-known that a drought in southern California in the mid-1970s led to a ban on filling backyard swimming pools, and these empty pools became playgrounds for freestyle skateboarders in the greater Los Angeles area. But a new cross-disciplinary study shows that beyond the drought, it was the entanglement of environmental, economic and technological factors that led to the explosive rise of professional skateboarding culture in the 1970s.
Published A new brew: Evaluating the flavor of roasted, lab-grown coffee cells
(via sciencedaily.com) Original source It may soon be time to wake up and smell the lab-grown coffee made from cultured plant cells. But it's not clear whether drinks from this product replicate coffee beans' complex flavors. Now, a study found that some of the comforting aromas and tastes of a conventional cup of coffee could be reproduced by roasting and brewing coffee cell cultures.
Published New study sheds light on how much methane is produced from Arctic lakes and wetlands
(via sciencedaily.com) Original source New study looked at lakes in the Arctic, including those at Alaska's Yukon Flats National Wildlife Refuge, to shed light on how much methane is produced from Arctic lakes and wetlands. Small unmapped lakes in the Arctic are far less abundant than previously thought, greatly reducing the cumulative methane emissions they were thought to contribute to Earth's atmosphere.

Published New insights into Zebra mussel attachment fibers offer potential solutions to combat invasive species, develop sustainable materials
(via sciencedaily.com) Original source A recent study has revealed that an unlikely event, occurring over 12 million years ago played an important role in shaping one of Canada's most damaging invasive species. Zebra and quagga mussels, belonging to the Dreissenid family, are widespread freshwater invasive species throughout North America that present a significant danger to native ecosystems by competing for resources. Using a fibrous anchor called a byssus, Dreissenid mussels contribute to biofouling on surfaces and obstruct intake structures in power stations and water treatment plants.
Published First global estimate of marine aquarium trade to encourage sustainable practices
(via sciencedaily.com) Original source New research estimates 55 million marine organisms worth $2.15bn are sold in the marine aquarium trade each year, making it as valuable as global fisheries such as tuna.
Published Three proposals from researchers to meet EU climate goals
(via sciencedaily.com) Original source The ability to meet EU climate goals is enhanced by investing in new technologies that remove carbon dioxide from the atmosphere. Although it is currently unprofitable for both companies and countries to do so, there are solutions to make it financially viable.
Published Urbanization increases seasonal differences in plant-pollinator networks
(via sciencedaily.com) Original source Increasing urbanization worldwide is a growing threat to biodiversity. At the same time, flowering plants are often more diverse in cities than in the countryside. This is due to flowering plants and agricultural crops, which are increasingly being grown in cities. A recent study shows that the interactions between plants and pollinators, which are important for agricultural production, are surprisingly dynamic. For example, the plant and bee species involved in pollination vary greatly between the seasons.
Published Sister climate cities, utility data predict future water, electricity demands
(via sciencedaily.com) Original source Modern-day Ciudad Mante, Mexico, could help Tampa, Florida, plan for shifting water and electricity demands due to climate change, according to an international team of researchers. Researchers used utilities data and climate analogs -- contemporary cities with climates close to what other cities are predicted to experience in the future -- to assess how climate change may impact residential water and electricity use across 46 cities in the United States.
Published It turns out, this fossil 'plant' is really a fossil baby turtle
(via sciencedaily.com) Original source Researchers re-examined a plant fossil found decades ago in Colombia and realized that it wasn't a plant at all: it's a fossilized baby turtle. It's a rare find, because juvenile turtles' shells are soft and often don't fossilize well.
