In and around the Gulf of St. Lawrence, where five Canadian provinces converge, a string of North American right whale deaths occurred throughout this summer. For scientists like Cornell University’s Charles Greene and Erin Meyer-Gutbrod who study these animals, the whales may represent another casualty of the ongoing climate crisis impacting the world’s oceans.

Coral skeletons are the building blocks of diverse coral reef ecosystems, which has led to increasing concern over how these key species will cope with warming and acidifying oceans that threaten their stability. New research provides evidence that at least one species of coral build their hard, calcium carbonate skeletons faster, and in bigger pieces, than previously thought.
A zone of water 30-50 feet below the surface of the Chesapeake Bay is increasing in acidity, threatening the health of the bay's shellfish.

Baleen whales are amongst the largest animals to have ever lived and yet very little is known about their breeding habits. One researcher’s second look at previously found baleen whale fossils from Japan provides new evidence of a now long-gone breeding ground of the extinct baleen whale Parietobalaena yamaokai dating back over 15 million years.
Behavior experiments are useful tools to study brain function. Standard experiments to investigate behavior in popular lab animals such as fish, flies or mice however only incompletely mimic natural conditions. The understanding of behavior and brain function is thus limited. Virtual Reality (VR) helps in generating a more natural experimental environment but requires immobilization of the animal, disrupting sensorimotor experience and causing altered neuronal and behavioral responses. Researchers at the University of Freiburg, and the Max F. Perutz Laboratories (MFPL), a joint venture of the University of Vienna and the Medical University of Vienna, in collaboration with groups at the Research Institute of Molecular Pathology (IMP) and the MPI for Ornithology in Konstanz, have now developed a VR system for freely moving animals – FreemoVR – to overcome most of these limitations. Their findings are now published in Nature Methods.
UC San Diego announces record-setting year in sponsored research support.
Coral reefs can’t seem to catch a break. Not only are rising temperatures wreaking havoc with their environment, but emerging evidence suggests that a certain sunblock component in many lotions that may help protect humans from developing skin cancer is a coral killer. Now, researchers have developed a biodegradable bead that can soak up the sunblock ingredient, oxybenzone, like a thirsty sea sponge. They hope to use the agent to clean up seawater at beaches.
After nearly two years of planning, a team of scientists from the U.S. and Cuba has explored never-before-studied mesophotic coral reefs along the entire coast of Cuba, spanning about 1,500 miles. Except for a few places along the coast, prior to this expedition, there were virtually no data or charts indicating what was beyond the shallow reef zone.

Sandia National Laboratories is testing whether one of California’s largest and most polluted lakes can transform into one of its most productive and profitable. Southern California’s 350-square-mile Salton Sea has well-documented problems related to elevated levels of nitrogen and phosphorus from agricultural runoff. Sandia intends to harness algae’s penchant for prolific growth to clean up these pollutants and stop harmful algae blooms while creating a renewable, domestic source of fuel.

Biodiversity Research Institute (BRI) announces that translocation of loon chicks from Maine to Massachusetts is being carried out this week. During the fifth breeding season of its Restore the Call project, BRI presents a progress report of the largest Common Loon conservation study ever conducted. Funded in 2013 by the Ricketts Conservation Foundation, Restore the Call is a five-year science-based initiative to strengthen and restore loon populations within their existing and former range. Research efforts have focused in three key U.S. breeding population centers from the western mountains to the Atlantic seaboard.
