Sapphires, known for their stunning blue color, are highly prized gems that are primarily composed of aluminum oxide, or corundum. Researchers at Heidelberg University have been delving into the formation of these unique crystals in volcanic melts. While sapphires are typically associated with silicon-poor volcanic rocks, the exact origin of these gems has long been

Peatlands in the Amazon basin have long been a topic of interest due to their critical role in regulating the global climate. A recent study led by researchers from the University of St Andrews, Scotland, and Charles University, Prague, has shed light on the vast extent of peatlands in the region through the development of
The recent research conducted by Chinese researchers and the UK Met Office, published in the journal Science, has shed light on the alarming increase in rainfall variability over the past century due to human-induced warming. This phenomenon has affected over 75% of the Earth’s land area, with notable impacts in Australia, Europe, and eastern North
The aftermath of the 2022 Hunga Tonga volcano eruption has been a subject of intense research and analysis by a collaborative team, including Dr. Andrew Dessler from Texas A&M University. The unique nature of this underwater eruption injected a significant amount of volcanic aerosols and water vapor into the atmosphere, leading to a reevaluation of
One of the most visible impacts of climate change is the increasingly erratic rainfall patterns observed worldwide. From intense downpours to prolonged dry spells, these changes in precipitation have raised significant concerns among scientists. A recent study published in the journal Science sheds light on the connection between human activities and the volatile nature of
In recent years, the demand for products delivered directly to consumers has driven a significant increase in the e-commerce and warehousing industry in the United States. However, a new study published in Nature Communications reveals alarming findings about the impact of large warehouses on air pollution in nearby communities. Researchers have found that people living
Imagine a world where synthetic chemicals that contaminate soil and pose a threat to the environment can be remediated in seconds. Thanks to the groundbreaking work of Rice University chemist James Tour and his research team, this dream is turning into a reality. In a recent study published in Nature Communications, the team introduced the
The recent study conducted by Alyssa Shiel, an environmental geochemist at Oregon State University, revealed shocking results regarding lead levels in urban moss samples. The research demonstrated that lead levels in older Portland neighborhoods with lead-sheathed telecommunication cables were up to 600 times higher than in rural areas. The implications of these findings are concerning,
The recent discovery made by an international team of researchers, including a chemist from Northwestern University, has unveiled a groundbreaking revelation – metallic minerals found on the deep-ocean floor are responsible for the production of oxygen, even 13,000 feet below the surface. This remarkable discovery challenges the long-standing belief that oxygen is solely generated by
The earthquake that hit western Morocco on 8 September 2023, with a magnitude of 6.8, had a devastating impact on rural communities in the High Atlas Mountains. This area, known for its seismic activity near the Rif Mountains, experienced a significant event that was a long time coming since the last major earthquake in 1960.
In the realm of greenhouse gases, not all are created equal. Each gas has its own global warming potential (GWP), which measures how much infrared thermal radiation the gas would absorb in the atmosphere over a specific period. Methane, for example, has a GWP about 28 times that of carbon dioxide (CO2) when measured over
Hurricanes are natural disasters that can cause significant damage and loss of life. In order to mitigate the impact of these storms, it is crucial to have effective evacuation orders in place. A team of University of Virginia researchers recently released the first-ever database of hurricane evacuation orders in the United States. This database, known
The recent observations which were published in the journal Progress in Oceanography shed light on the impact of the collapse of a giant iceberg in the sub-Antarctic on ocean ecosystems. This groundbreaking study, conducted by a team from the British Antarctic Survey (BAS) and the National Oceanography Centre (NOC), provides valuable insights into how warmer
Nature-based solutions (NbS) have emerged as a powerful and cost-effective method to mitigate risks associated with a wide range of disasters, such as floods, hurricanes, heat waves, and landslides. These solutions involve preserving, sustainably managing, or restoring ecosystems to provide benefits to both society and nature. NbS have gained recognition in major national policies and
Recent research conducted by North Carolina State University has shed light on the alarming rate at which the global apparel industry is contributing to plastic pollution in the environment. The study found that in 2019 alone, over 20 million tons of plastic waste was generated from the production and consumption of apparel around the world.
