Fire Management in California's Chaparal: The U.S. Army Corps of Engineers Sacramento District conducted a controlled burn of central marine chaparral at Fort Ord, Calif., Oct. 15, to expose unexploded ordnance at the formerly utilized defense site. The burn, carefully coordinated with local agencies, lasted less than two hours and was timed so that prevailing winds would help blow the smoke away from population centers. The controlled burns are part of a comprehensive ordnance removal program at Fort Ord, which closed in 1994 under recommendation from the Base Realignment and Closure Commission.

Fire Management in California’s Chaparral Harms Birds

By Neha Jain @lifesciexplore California suffered its largest and most destructive wildfires in 2017. Victims included hundreds of wild animals. When the blazing fires were finally extinguished, the surviving animals—including birds—were forced to find new homes. Now, for the first time, researchers investigating the effect of fire management practices on birds in California’s chaparral have found that one practice known as mastication, which consists of mechanically crushing vegetation to remove fuel, threatens bird communities. “The best available science tells us that managing chaparral imperils wildlife and increases fire risk,” says…

What’s Jupiter Hiding?

By Steven Spence @TheStevenSpence Juno: Aptly named The Juno spacecraft currently orbiting Jupiter is appropriately named. In Roman mythology, Jupiter created a veil of clouds to hide his escapades with Io from his wife, Juno, but Juno was able to peer through the clouds and foil his plan. The Juno spacecraft, currently on its 11th science orbit[1] of Jupiter, is designed to see through Jupiter’s clouds, revealing secrets of the planet’s atmosphere and interior. Boldly going on a five-year mission Juno launched on August 5, 2011, from Cape Canaveral aboard…

Honeybees Are Attracted to Fungicides and Herbicides

By Neha Jain @lifesciexplore Whenever you eat fruits, vegetables, and nuts, take a moment to thank honeybees for their pollination services that contribute $17 billion to the US economy each year. In fact, almonds are almost solely dependent on honeybees for pollination. Populations of these much-needed pollinators have mysteriously plunged over the past decade, and many studies suggest a link to the use of neonicotinoid insecticides among other factors such as climate change and disease. Recently, scientists found that honeybees prefer sugar water laced with the fungicide chlorothalonil and the…

Why Do Humans Have Thumbs and Not Fins?

Did you know we can trace the evolution of our hands, and thumbs, back to a 375 million-year-old fish called Tiktaalik? Watch this video with paleontologist and geneticist Dr. Neil Shubin to learn what a fish and a little blue hedgehog can teach us about the evolution of thumbs. This is a video from Dr. Joe Hanson’s It’s Okay To Be Smart series.     Tiktaalik is a 375 years-old fish with fins. When we look under its fin rays and take off the scales, what we find are versions of our…

How Have Snapping Shrimp Evolved to Snap?

By Hallie Macdougal By using computer modelling and 3-D printing and mapping evolutionary trees, researchers at the University of Alberta have discovered a possible evolutionary pathway that shows how snapping shrimp have evolved to “snap.” Snapping shrimp, also known as pistol shrimp or alpheid shrimp, compete with whales for the title of loudest animal in the ocean. To make noise, snapping shrimp are able to close their claws incredibly fast, which shoots a stream of water so quickly that new water from above doesn’t have time to replace it, creating…

California’s Urban Forests Have Lowest Tree Cover per Resident

By Neha Jain @lifesciexplore California’s urban forests are not just a pretty sight; they are an asset valued at a whopping $181 billion, finds a new study. But, according to the study, the state’s urban tree cover at 90.8 square meters (109 square yards) per city resident is the lowest among all US states. The good news is that there are 236 million spots available for more trees to be planted. The study finds that urban forests cover 15 percent of the urban area in California, consisting of 173 million…

Language Detectives

Where did the Uto-Aztecan language originate? An interdisciplinary research project looked at a set of 100 words to understand the sound sequences of this language. Watch this video to see how an anthropologist and a computational biologist carried out this research. This is another in the Shelf Life series from the American Museum of Natural History. Museum curators Peter Whiteley, an anthropologist, and Ward Wheeler, a computational biologist, joined forces to trace the evolution of Native American languages by applying gene-sequencing methods to historical linguistics. I became fascinated by the idea…

Math Structures the World around Us

From Google searches to sunflowers’ structures, we can look at and understand the world around us through the lens of math. Watch this video by Techsploration to know more about the critical skills you can develop by studying math. Math can not only help us understand the structure of the world around us but also lead to many job opportunities, from epidemiology to finance and from business to teaching. The cool thing about math is that it’s all around us. Whether you realize it or not, you are using math and…

Do Humans Influence Jellyfish Coastal Populations?

By Laura Treible @aqua_belle Jellyfish are a common nuisance to beachgoers in the summertime, but why certain years have massive jellyfish blooms while others do not is often a mystery. In recent years, some areas appear to have larger and more frequent blooms, so it is important to determine the causes of blooms in general, as well as whether jellyfish blooms are increasing. How humans impact jellyfish Human activities such as changing our global climate, fishing, and increasing pollution or nutrients entering waterways influence the oceans in many ways. Some…

Is Climate Change Causing These Moose to Shrink?

By Emily Rhode @riseandsci The effects of climate change are starting to show themselves in strange and unexpected ways. For the cold-adapted moose of Isle Royale, Michigan, a warming environment could literally be causing them to shrink. According to researchers at Michigan Technological University, the flourishing moose population at the heart of the world’s longest-running predator-prey relationship study is displaying alarming changes that may be most readily explained by environmental pressures. The soon-to-be-released 60-year study of the dynamics between the moose and wolf population of the tiny island in the…
