Unique data confirms why water turns brown
(Lund University) By analysing almost daily water samples taken from the same river from 1940 until today, researchers at Lund University in Sweden have confirmed their hypothesis that the browning of lakes is primarily due to the increase in coniferous forests, as well as rainfall and sulphur deposits.

Ground-breaking Clean Air Protocol to Guard Human Health and the Planet, Enters into Force
Credit: Bigstock.By External SourceUNITED NATIONS, Oct 5 2019 (IPS) European and North American countries will take a major stride in cleaning up the atmosphere next Monday, 7 October, through the implementation of an amended legally binding treaty to limit the amount of emissions polluting the air.
With 18 countries and the European Union now having ratified the amended treaty, from a total of 51 who have signed, including many of the countries which are part of the UN Economic Commission for Europe (UNECE), the official entry into force marks an important step to curb pollutants closely-linked to climate ch...

Country diary: a dowdy female with the vapours gets male moths a-flutter
Langstone, Hampshire: Potential mates can detect the emergence of an adult vapourer moth from miles awayIt was impossible to miss therusty tussock moth (Orgyia antiqua) caterpillar foraging on my raspberry bush. Its body was dotted with orangey-red pinacula, wart-like growths sprouting clusters of pale lemon hairs. It had two bristly black antler-like protrusions at the front of its head, and a tail-like projection from its rear. Along its back four sulphur-yellow dorsal tufts stood proud, like the bristles of an interdental toothbrush. Measuring it at 25mm in length, I could tell it was a female, as males reach a maximum ...

How the Apollo Program Changed Our Understanding of What the Moon Even Is
As the ancient planet Theia struck its glancing blow into Tellus, the planet that would become Earth, part of its mantle sloughed off into that of the planet it had struck, but some drove on past, pushing a layer of Tellurian mantle ahead of it like mud on the blade of a bulldozer. Still traveling with more than half of Theia’s original speed, blade and burden rose together back out into space. Much fell back. Much did not. Some escaped completely to form a short-lived ring around the Sun. But a lot stayed in orbit around the wrecked, reforming planet below. It was from that fiery orbital aftermath that the Moon was ...

Scientists discover Snowball the cockatoo has 14 distinct dance moves – video
A sulphur-crested cockatoo named Snowball garnered YouTube fame and headlines a decade ago for his uncanny ability to dance to the beat of the Backstreet Boys. Now, researchers reporting in Current Biology are back with evidence that Snowball is not limited in his dance moves. Despite a lack of dance training, videos show, Snowball responds to music with diverse and spontaneous movements using various parts of his bodyContinue reading...

Graphene sponge helps lithium sulphur batteries reach new potential
(Chalmers University of Technology) To meet the demands of an electric future, new battery technologies will be essential. One option is lithium sulfur batteries, which offer a theoretical energy density more than five times that of lithium ion batteries. Researchers at Chalmers University of Technology, Sweden, recently unveiled a promising breakthrough for this type of battery, using a catholyte with the help of a graphene sponge.

A cause of possible genetic problems in mitochondria is revealed
(University of Seville) The loss of mitochondrial information and of mitochondria gives rise to defective cell metabolism. As well as the lack of capacity to generate the energy necessary for the cells, the loss of mitochondrial information can generate an increase in oxygen free radicals that attack and damage the genetic material or produce Iron-Sulphur protein deficiencies. All this brings about incorrect cell functioning and eventually cell death. (Source: EurekAlert! - Biology)
