Some 9,000 years ago, residents of a large farming community were also among the first humans to experience some of the perils of modern urban living. Scientists studying the ancient ruins of Çatalhöyük, in modern Turkey, found that its inhabitants — 3,500 to 8,000 people at its peak — experienced such modern urban problems as ...
Many pesticides that have been banned or are being phased out in the EU, Brazil, and China are still widely used in the U.S., according to a study published in the open-access journal Environmental Health. Study author Nathan Donley, at the Center for Biological Diversity, U.S., said: “The USA is generally regarded as being highly ...
The nuclear lamina (NL) is a thick protein network present inside the nucleus of cells. It is known to regulate critical cellular activities like DNA replication and cellular division. In addition, it also provides the cells with mechanical support. Now, a team of scientists has identified another important role of the NL — to arrange ...
On May 23, SpaceX launched 60 satellites into space. A part of the Starlink project, these are the first batch of a proposed 12,000 that the company plans on deploying in Earth’s orbit to give wireless broadband Internet access to the entire world. However, astronomers are not happy about the project and are accusing Musk’s ...
Human exposure to unnecessary and potentially harmful chemicals like PFAS could be significantly reduced if manufacturers added chemicals only when they were truly essential in terms of the health, safety, and functioning of society. That’s the conclusion of a study published in Environmental Science: Processes & Impacts, a peer-reviewed journal published by the Royal Society of ...
The huge magnetic field that surrounds the Earth, protecting it from radiation and charged particles from space — which many animals even use for orientation purposes — is changing all the time, which is why geoscientists constantly keep it under surveillance. The old well-known sources of the Earth’s magnetic field are the Earth’s core — ...
Coal ash solids found in sediments collected from Sutton Lake in 2015 and 2018 suggest the eastern North Carolina lake has been contaminated by multiple coal ash spills, most of them apparently unmonitored and unreported until now. Avner Vengosh, professor of geochemistry and water quality at Duke University’s Nicholas School of the Environment, who led the ...
Laboratory tests conducted nearly 20 years ago that have gone largely unreported found high levels of the toxic fluorinated chemical known as PFAS in several popular supermarket foods. The tests were commissioned by 3M, the giant chemical company that first manufactured the two most notorious members of the PFAS family, PFOS and PFOA. Last year, ...
Scientists believe they have discovered the site of the biggest meteorite impact ever to hit the British Isles. Evidence for the ancient, 1.2 billion-year-old meteorite strike was first discovered in 2008 near Ullapool, N.W. Scotland, by scientists from Oxford and Aberdeen Universities. The thickness and extent of the debris deposit they found suggested the impact ...
The Chinese lunar rover Chang’e 4 has found what seems to be the first indication of minerals in the Moon’s mantle. The discovery was made by researchers from the National Astronomical Observatories at the Chinese Academy of Sciences. Minerals on the Moon In early January, the Chang’e 4 lunar rover landed inside the Von Karman ...
