Comments Off on Tiny treadmills for turtle hatchlings help scientists evaluate their stamina

When baby sea turtles are born, within their first 24 hours they make the journey from nest to ocean . The trek which should take a few minutes sometimes lasts hours in urban settings where artificial light can disorient the hatchlings. Two Florida Atlantic University (FAU) scientists employed wee treadmills and little swimsuits to dig into the turtles’ swimming performance after crawling for so long – and they were surprised by what they found. Speed is crucial for turtle hatchlings, who face dangers on their way to the ocean. Their survival “depends heavily on their ability to swim,” according to FAU. But in urban settings, excess light from streets and buildings can draw the babies away from the ocean and towards land – where they might get run over by traffic, drown in a pool, or be eaten by a predator. Biological sciences associate professor Sarah Milton said in a statement, “What prompted our study was the desire to understand what happens to these hatchlings after they spend hours crawling on the beach because they are disoriented. We wanted to know if they would even be able to swim after crawling 500 meters or more, which could take them as long as seven hours to complete.” Related: Police Officer Saves Nearly 100 Baby Sea Turtles in Florida Milton and graduate student Karen Pankaew conducted what FAU described as the “first study on disorientation to examine the physiological effects of extended crawling and swimming performance.” They gathered 150 hatchlings from 27 loggerhead and 18 green turtle nests in Palm Beach County, Florida . The hatchlings walked on tiny treadmills before swimming in a tank in a specially designed swimsuit. The scientists measured oxygen consumption, lactate accumulation, and swimming breathing and stroke rates. Field studies supplemented laboratory observations. The hatchlings were placed into the ocean in their natural habitats shortly after collection. The study results completely surprised the researchers, according to Milton, who said, “We were expecting that the hatchlings would be really tired from the extended crawling and that they would not be able to swim well. It turned out not to be the case and that they are in fact crawling machines. They crawl and rest, crawl and rest and that’s why they weren’t too tired to swim.” She also said the study offers a scientific basis to back up lighting ordinances during hatching season.

"Microplastics have been found in mussels everywhere scientists have looked"

Mussels might serve as a global “bioindicator of microplastic pollution ,” Chinese researchers suggested last year, as the creatures remain in the same area and reside on the seabed where plastic ends up. And a new study from the Norwegian Institute for Water Research (NIVA) uncovered plastic in 76.6 percent of individual blue mussels they tested. Reuters pointed to other surveys where researchers found microplastics in mussels near China, Belgium, Britain, Canada, and Chile. NIVA Researcher Amy Lusher told Reuters, “Microplastics have been found in mussels everywhere scientists have looked.” The new NIVA research found on average 1.8 pieces of microplastic in mollusks near Norway, while and mussels living in waters thought to be pristine in the Arctic actually had the greatest amount of plastic among any of the creatures tested near the Norwegian coast. Lusher said ocean currents and winds from American and Europe may be sweeping plastic north, where it might then swirl in the Arctic Ocean. Related: Plankton Pundit video shows exact moment plastic enters the food chain Scientists aren’t quite sure how microplastics in marine life will impact humans that consume them, but think you’d have to eat a whole lot of shellfish to be at risk. Microplastics expert and Plymouth University professor Richard Thompson told Reuters of the global discoveries, “It’s a warning signal that we need to do something about reducing the input of plastic to the ocean. It’s a cause for concern at the moment rather than an alarm story for human consumption.” You can check out the NIVA report here .

Gamercize PC Sport The Gamercize PC stepper turns your workday into an exercise challenge by disabling your technology unless you are in motion. That’s right, the stepper is connected to you keyboard and mouse, so that they freeze if you are not moving. You can use the Gamercize while seated, or at a standing desk . Exercise Ball Chair Sitting on an exercise ball will help tone your abs and back, but make sure your setup is considering ergonomics. Select the correct sized ball so that you are sitting with your legs at a 120 degree angle to the floor with your feet flat. The key is to use your muscles all day long while on the ball to keep you from slouching. If your core is not already strong, you may want to start off with half days of using the ball, so as not to injure your back. Livestrong has more great tips on using your ball correctly at your desk. photo by Elizabeth Skene Mini Stationary Exercise Bike I first saw a mini exercise bike in use when the coworker in the “cube” next to me bought one. He got a lot of weird looks at first for his enthusiasm of peddling all day long, but also we were all really curious to try it ourselves. One thing to note is that there are several companies that sell these mini desk bikes, and they vary in their level of adjustability for resistance and also the noise they produce. The model my co-worker uses does produce an obvious whooshing sound that attracts attention, but the Magne Trainer ER has many high ratings for it silent action.

m-louis / Creative Commons The stag beetle is the largest terrestrial insect in the United Kingdom but finding the elusive species has always been a challenge. Conservationists fear that the beetle’s numbers may be declining but without an accurate count of the population, no effective protection plan can developed.
