Scientists develop mesh that captures oil but lets water through and could help clean oil spills. The work was partly inspired by lotus leaves, whose bumpy surfaces naturally repel water but not oil.
The number of US fish stocks listed as overfished, or subject to overfishing, has dropped to an all-time low since NOAA Fisheries began monitoring began in 1997. Their report, released this week, highlights the United States’ continued progress towards sustainably managing fish stocks. NOAA Fisheries maintain three lists: Overfishing, Overfished and Rebuilt. A fish stock […]
The ocean is vast and has been greatly explored in the last decades. But there is still much to be discovered. With clear plans for 2015, NOAA’s research vessel – the Okeanos Explorer – has already begun its field season and is currently mapping in the Caribbean. Last year saw two successful expeditions, one in […]
We all have our favourite types of environment and weather. Some love those warm, sunny days spent on a beach of golden sands. Some love those rainy days in the forest, when everything glistens with the raindrops. Some love nothing more than a cold crisp day in snowy mountains. We humans are lucky. We can […]
Brazil fisheries have no bag or size limits for any species of fish and even the most basic fisheries statistics, such as the numbers and weights of fish being caught, are a blank space. The newly published Red List of Brazilian species at risk from extinction, identifies 83 types of marine animal aslo commercially exploited by fisheries. The Galapagos shark is an example of a keystone species thought to have been fished to regional extinction due to decades of nonexistent fisheries regulations. This species is one of many that could have greatly benefited from management plans that help reduce by-catch and prevent the overexploitation of fishing stocks.
Methane is a potent greenhouse gas that traps heat about 20 times more effectively than carbon dioxide. Understanding the sources of methane, and how the gas is formed, could give scientists a better understanding of its role in warming the planet. Now a research team including scientists at the Massachusetts Institute of Technology, the Woods […]
World Animal Protection are asking divers to report “ghost” fishing gear. They say that an estimated 640,000 tonnes of fishing gear is lost or abandoned in our oceans each year, entangling and killing millions of animals including seals, turtles and whales. When divers see or remove any ghost gear, they can upload their sighting which […]
Remote monitoring of large swathes of inaccessible ocean from satellites that orbit the Earth some 700 km above our heads is set to revolutionise the way that marine biologists and climate scientists study the ocean. Every year more than a quarter of global CO2 emissions from burning fossil fuels and cement production are taken up […]
When tunas dive down to cold depths their body temperature stays warm but their heart temperature can fall by 15 degrees within minutes. The heart is chilled because it receives blood directly from the gills which mirrors water temperature. This clearly imposes stress upon the heart but it keeps beating, despite the temperature change. In most other animals the heart would stop.
Humans are not infallible. We get sick, we get injured. Humans are a clever bunch though, and since prehistoric times we have used medicine to try and heal our ailments. Medical science has made huge leaps and bounds, providing treatments and vaccinations, surgical procedures, and physical and psychological therapies that have allowed people to survive […]
