An international study led by Monash University scientists has found that the distance traveled by marine larvae is dictated by both biological and physical constraints-contradicting previous hypotheses based on biology or physics alone.

A study of nearly 2,000 Marine recruits who went through supervised quarantine before starting basic training revealed several instances of asymptomatic transmission of SARS-CoV-2, the virus that causes COVID-19, despite the quarantine measures.

Dr. Arnott added: "Our research shows for the first time how microplastics are disrupting and causing behavioral changes among the hermit crab population. These crabs are an important part of the ecosystem, responsible for 'cleaning up' the sea through eating up decomposed sea-life and bacteria. By providing a hard, mobile surface, hermit crabs are also walking wildlife gardens. They host over 100 invertebrate species-far more than live snails or non-living substrates. Additionally, commercially valuable species prey on hermit crabs, such as cod, ling, and wolf-fish. With these findings of effects on animal behavior, the microplastic pollution crisis is therefore threatening biodiversity more than is currently recognised so it is vital that we act now to tackle this issue before it becomes too late."

The findings, published in Science Robotics, demonstrate that the new underwater robot can swim as quickly and efficiently as the squid and jellyfish which inspired its design, potentially unlocking new possibilities for underwater exploration with its lightweight design and soft exterior.

"he Army, Navy, Air Force and Marine Corps will also phase out their programs to train uniformed strategists and retire serving strategists, which will save billions of dollars, Mattis said. Meanwhile, civilian consultants will replace strategists across the Department of Defense. According to the contract, their key duties will include producing PowerPoint briefings with graphics that no one understands, writing white papers that will not be read by policymakers, faking expertise on countries they have never visited (primarily China and Russia), and repeatedly saying "whole of government," all at a much lower cost than what the Pentagon currently spends for similar duties."

group of researchers from three Japanese universities has discovered why the western subarctic Pacific Ocean, which accounts for only 6 percent of the world's oceans, produces an estimated 26 percent of the world's marine resources.

Every time you wash your clothes, thousands of tiny microfibres from the fabric are released into rivers, the sea and the ocean, causing marine pollution. Scientists have speculated for some time that these microfibres may cause more harm than microbeads, which were banned from UK and US consumer products in recent years. Researchers from Northumbria University worked in partnership with Procter & Gamble, makers of Ariel, Tide, Downy and Lenor on the first major forensic study into the environmental impact of microfibres from real soiled household laundry. Their forensic analysis revealed an average of 114 mg of microfibres were released per kilogram of fabric in each wash load during a standard washing cycle.
