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. The Journal of Experimental Biology published the study in November. Via Florida Atlantic University Images via Pixabay and Jay Paredes

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

Comments Off on "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.

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 .

Scientists discover that exploding stars impact weather on Earth

Comments Off on Scientists discover that exploding stars impact weather on Earth

Researchers at the Technical University of Denmark  have learned that cosmic rays emitted when stars explode have a measurable impact on weather patterns on Earth. Supernovae, which occur at the very end of a star’s life and result in a massive explosion, discharge cosmic rays, affecting cloud formation upon reaching Earth’s atmosphere . As cloud formation increases, weather on Earth becomes cooler. “Finally we have the last piece of the puzzle explaining how particles from space affect climate on Earth,” said Dr Henrik Svensmark, lead author of the study published in Nature Communications . “It gives an understanding of how changes caused by solar activity or by supernova activity can change climate.” Researchers discovered that cosmic rays released by supernovae knock electrons out of atmospheric particles on Earth, creating ions which increase the number of cloud concentration nuclei, the “seeds” for cloud formation. Ionization allow aerosols, small clusters of molecules packed into air or another gas, to survive for longer in the atmosphere, enabling them to form cloud concentration nuclei more easily. Since cloud cover has a significant impact on the amount of solar energy that reaches Earth’s surface, this discovery sheds light on climate events in the past and helps to better predict the future. Related: New periodic table sorts 3,700 known exoplanets into 18 categories For example, the relationship between supernovae and cloud formation has strengthened the case that changes in solar activity played a key role in the Medieval Warm Period (~1000 AD) and the cold period in the Little Ice Age (1300-1900 AD). The researchers also discovered that the Sun affects how many cosmic rays reach Earth, which impacts the magnitude of a supernova’s effect on Earth’s climate. When the sun is magnetically active, less cosmic rays reach Earth; when it is dormant, there is a greater concentration of cosmic rays hitting Earth’s atmosphere. The impact of cosmic rays and solar activity on Earth’s climate may have contributed to recent climate events, such as changes observed in the 20th century and the warming-cooling of about 2 degrees Celsius over the past 10,000 years.

Comments Off on Beautifully renovated Norwegian cottage combines old and new under one pitched roof

This fifty-year-old cottage designed by architect Atle Sørby was renovated entirely by Local craftsmen in Time, Norway. Norwegian design studio bark arkitekter redesigned the home while taking care to balance modern functional requirements with the original architecture. The Selestranda House occupies a relatively flat site surrounded by long sloping fields, dunes and beaches, separated only by narrow roads and old drystone walls . It features a pitched roof with pulled-down gables which the original architect used to reinterpret the traditional housing typology of the region, which is designed to withstand harsh weather conditions . Related: Snøhetta Turns Old Wooden Boathouse into a Sweet Camping Retreat in Norway The renovated cottage comprises two volumes–a new annex that contains a bedroom, a bathroom and a storage room, and the main volume that houses a large common room, a shared kitchen, and eating and living areas. Local craftsmen carried out every part of the renovation process. The roof tiles, created by local brick-factories in Sandnes, were carefully taken down, stored and put up again, one by one. In order to create an open-plan layout, the architects decided to take down the walls and ceiling in the common area. This also provided enough space for a ribbon window that offers panoramic views of the landscape. + bark arkitekter Via Archdaily Photos by Lise Bjelland

Comments Off on Police Officer Saves Nearly 100 Baby Sea Turtles in Florida

Police officers are sworn to serve and protect the members of their community. For some cops, this extends even to the non-human residents under their watch. As he was patrolling the Lido Beach Resort in South Florida on Saturday August, 3 around 1 am, Officer Derek Conley spotted a group of baby sea turtles clustered around the hotel’s front door. A passerby told him that there were more of the obviously confused hatchlings in the parking lot. After calling the area’s two marine rescue groups, Conley—along with several guests—collected almost 900 babies into a box, and led them to the ocean. He even stopped traffic on several occasions to chauffeur his shelled charges into their rightful home in the nearby Gulf of Mexico .
