Ten years after the state of California recognized the human right to water, hundreds of thousands of residents still rely on drinking water that contains dangerous levels of contaminants, including the highly toxic mineral arsenic. Many of them live in low-income and rural communities that struggle to afford the necessary infrastructure to remove arsenic from drinking water.
Paleontologists have identified a new genus and species of algae called Protocodium sinense that predates the origin of land plants and modern animals and provides new insight into the early diversification of the plant kingdom.
During fieldwork aimed at documenting the stone tool use of a group of wild chimpanzees in the Taï Forest in Cote d'Ivoire in early 2022, the researchers identified and 3D-scanned a variety of stone tools used to crack different nut species. Their study is now published in Royal Society Open Science.
Research into the synthesis of new materials could lead to more sustainable and environmentally friendly items such as solar panels and light emitting diodes (LEDs). Scientists from Ames National Laboratory and Iowa State University have developed a colloidal synthesis method for alkaline earth chalcogenides. This method allows them to control the size of the nanocrystals in the material. They were also able to study the surface chemistry of the nanocrystals and assess the purity and optical properties of the materials involved. Their research is discussed in the paper "Alkaline-Earth Chalcogenide Nanocrystals: Solution-Phase Synthesis, Surface Chemistry, and Stability," published in ACS Nano.
Methamphetamine is a stimulant that can be taken as a recreational drug, either by injections or smoking. It is classified as a Class A drug in the UK and its recreational use is criminalized in many countries throughout the world.
In mythologies and origin stories around the world, various cultures and religions point to clay as the vessel of life, the primordial material that creator gods imbued with a self-sustaining existence. Nowadays we have biology to explain how life comes to be, but could these tales of old hit closer to the mark than we think?
