Recursive language and modern imagination were acquired simultaneously 70,000 years ago

Article, link to the paper at the end of it.

Kinda fun. I wonder how it must've been for the first ones to speak proper language when they talked with their parents ;D

A new way to decompose microplastics could help clear waterways of these tiny bits of trash, which may pose health risks to people and other animals. In the future, water treatment facilities that employ carbon nanomaterials may not only help prevent new microplastic pollutants from entering the environment, but also potentially remove the particles from polluted waterways. Jian Kang, a chemical engineer at Curtin University in Perth, Australia and colleagues tested their technique on 80 mL water samples contaminated with microplastic particles. Carbon nanotube treatment in water warmed to 120°C for eight hours reduced the amount of microplastic in the water by about 30 to 50%. Kang and colleagues are now working to refine their nanotubes to break down microplastics more efficiently without the help of high temperatures. [Article] [Publication]

That is very cool. There's been lots of research and media attention in Finland recently too about how to remove microplastic from wastewater. It's just sad that most of those technologies are not going to apply to saving the oceans from it, but at least inland lakes might be salvageable, which is of course awesome!

Speaking of...

Plastic Teabags Release Billions of Microparticles and Nanoparticles into Tea

Abstract Image
The increasing presence of micro- and nano-sized plastics in the environment and food chain is of growing concern. Although mindful consumers are promoting the reduction of single-use plastics, some manufacturers are creating new plastic packaging to replace traditional paper uses, such as plastic teabags. The objective of this study was to determine whether plastic teabags could release microplastics and/or nanoplastics during a typical steeping process. We show that steeping a single plastic teabag at brewing temperature (95 °C) releases approximately 11.6 billion microplastics and 3.1 billion nanoplastics into a single cup of the beverage. The composition of the released particles is matched to the original teabags (nylon and polyethylene terephthalate) using Fourier-transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS). The levels of nylon and polyethylene terephthalate particles released from the teabag packaging are several orders of magnitude higher than plastic loads previously reported in other foods. An initial acute invertebrate toxicity assessment shows that exposure to only the particles released from the teabags caused dose-dependent behavioral and developmental effects.

A few milion years ago, around the time when Lucy and other early hominids were walking around in Africa, the heart of the Milky Way saw a series of super-powerful explosions and flare-ups, and at the time the core region must have been much more luminous than today, even in the night skies of Earth. And it didn't come and go overnight, either: this "active phase" is presumed to have lasted for around 300.000 years. All of it happening in connection with the huge black hole that still resides at the central point of our galaxy.

Amazing. :)

Press Release! The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Chemistry 2019 to John B. Goodenough (University of Texas), M. Stanley Whittingham (Binghamton University), and Akira Yoshino (Meijo University) for their contributions to the development of the lithium-ion battery. This lightweight, rechargeable battery is used worldwide in electronic devices such as cellphones, laptops and electric vehicles, the last of which can store significant amounts of energy from renewable sources, making a fossil fuel-free society possible in the future. An award well deserved, if not a bit overdue. [Press Release] [Technology Information] [Scientific Background]
