Not a plane, bird or frog, it’s a 600-pound satellite hurtling toward Earth — and it’s set to make its crash landing tomorrow. NASA reported on Monday that the retired Reuven Ramaty High Energy Solar Spectroscopic Imager spacecraft, otherwise known as RHESSI, will reenter Earth’s atmosphere on Wednesday after over two decades

Carbon emissions from boreal forest fires more than doubled in 2021, pointing towards a worrying new trend that could exacerbate climate change, scientists have said. Boreal forests, or taiga, is a biome characterised by coniferous forests consisting mostly of pines, spruces, and larches. While they typically account for 10 per cent of

Foundation heave is the uplift, elevation of a foundation precipitated by soaked, expanding soils and can generally be attributed to a seasonal increase in moisture, a plumbing leak, or underground aquifers. Foundation heave is a phenomenon that occurs when the soil beneath a building's foundation expands, causing the foundation to rise.

With the impact of climate change around the globe, the push for corporate sustainability initiatives has never been greater As we continue to see the impact of climate change around the globe, the push for corporate sustainability initiatives has never been greater. It is increasingly essential that organisations develop and adopt

A new understanding of how particle shape controls grain flow could help engineers manage river restoration and coastal erosion. As a river cuts through a landscape, it can operate like a conveyer belt, moving truckloads of sediment over time. Knowing how quickly or slowly this sediment flows can help engineers plan

Injecting chemicals to stabilize, lift, seal or compact weak soils and rocks is not new. Polyurethane grout material has been used for this purpose since the 1960s. However, the limitations of this process have often been frustrating, not only for asset owners but installers, as well. Historically, material injection has

UK forests may store almost double the amount of carbon than previous calculations have suggested, scientists believe. UCL researchers used a 3D-scanning technique and analysis to assess the amount of aboveground biomass (AGB) – used to derive carbon storage – of 815 trees in a UK woodland. The team found that their

A new drilling technology could unlock the key to almost limitless geothermal energy, potentially helping to wean the world off its use of fossil fuels which are contributing to the heating of the planet. The deepest hole drilled to date - the Kola borehole - went 7.6 miles down. It took

We shall go through the introduction of soil nailing, its uses, advantages and disadvantages, design criteria, construction methodology, and performance checks. What Is Soil Stabilization? Soil stabilization is the act of altering a soil’s physical properties to provide long-term, permanent gains in strength. A soil is stabilized by enhancing its shear strength

The race to remove CO2 from our atmosphere is on. In an effort to draw down carbon at a meaningful scale, people are looking to the ground. The top meter of the world’s soil holds over three times the amount of carbon currently in our atmosphere—and if we treat our land better,
