The geological timescale is a chronological representation of Earth’s history that is divided into four main eons, the Hadean, Archean, Proterozoic, and Phanerozoic, each of which is characterized by the emergence of different life forms and geological events. The geological timescale is vital in understanding the Earth’s history and the evolution of life. Scientists study different types of rocks to…
Rising global temperatures are causing the Arctic’s glaciers to melt at an alarming rate, which is affecting the region’s topography and ecosystem. Glacier melting is causing rising sea levels, coastal erosion, flooding, and increased risk of storm surges, while also impacting the permafrost and river systems. As the permafrost thaws, it leads to unstable ground and increased risk of landslides…
Researchers from the University of Oregon have identified a new species of bacteria living in extreme conditions at the volcanically located Crater Lake in the United States. The bacteria, which is exhibiting unique genetic characteristics, was discovered using highly advanced DNA sequencing techniques. The water in the lake is highly alkaline and freezing, making it a challenge for living organisms…
A new continent that covers an area of 1.5 times the size of the European Union has been discovered in the southern hemisphere. The previously unrecognised landmass, named Zealandia, broke off from Australia around 85 million years ago. Zealandia is important for its unique ecosystem and its potential to offer insights into plate tectonics, seafloor spreading and how rocky planets…
Iceland’s glaciers and mountains offer a unique and awe-inspiring sight to behold. The largest glacier in Iceland and second-largest in Europe, Vatnajökull, is a popular destination for glacier exploration with its glacial lagoons and ice caves. The mountains of Iceland, shaped by volcanic activity, offer opportunities for exploration and breathtaking views, with Mount Kirkjufell and Mount Hekla being popular spots….
Landscape architects in Atlanta have unveiled plans to revitalize a park in a low-income neighbourhood that has been neglected for investment and resources. The plan includes elements of sustainable design, such as permeable paving, rain gardens and native plantings, as well as renewable energy sources, to reduce the carbon footprint of the park. The design team is also working with…
New studies of the Amazon rainforest have identified previously unknown hotspots of species richness, helping to shed light on its biodiversity and offer hope for the conservation of this vital ecosystem. High-resolution satellite imagery has allowed scientists to identify areas with the highest levels of biodiversity, and identify areas with high levels of biological and ecological importance. The discovery of…
Researchers at the University of Bayreuth in Germany, in collaboration with colleagues in Japan and the United States, have discovered a new mineral in the Earth’s mantle called Grossite, which is made up of calcium and aluminum with a high melting point. This is the first time the mineral has been identified in the Earth’s mantle, and its discovery could…
Organic farming is increasingly popular due to concerns around the environment and sustainability. Pesticides and fertilisers used in conventional farming can leave residues on food, which are avoided through natural methods, such as crop rotation and companion planting. Organic farming also encourages the wellbeing of animals, resulting in higher levels of nutrients found in organic fruits and vegetables. Despite organic…
A powerful tornado swept through the Midwest, causing destruction and damage across several towns and cities, including Lawrence and Kansas City in Kansas. The tornado damaged buildings, uprooted trees, and threw cars around like toys. Power outages also affected thousands of residents. Emergency crews, the National Guard, and volunteers have been working around the clock to assess the damage and…
