Biden's Climate Plan
Despite Trump's attempt to break US democracy in order to alter reality to his liking, Joe Biden will be sworn in as the next president. This has obvious implications for US's plans for tackling climate change. The first is that we will now have an executive branch that recognizes science, that climate change is real, and will actually try to do something about it. Immediately this means rejoinin

Elevassistenter kan hämma lärandet
Elevassistenter är numera en större yrkesgrupp än fritidspedagogerna i den svenska skolan. På många håll brottas de med tuffa pedagogiska utmaningar som resurser till elever i behov av särskilt stöd, men de har låg eller ingen pedagogisk utbildning alls. Forskning saknas om hur deras insats påverkar elevernas resultat, enligt en ny översiktsstudie vid Linköpings universitet.

Rättvisemodell ska hjälpa föräldrar vid vårdnadstvister
Föräldrar ska själva sporras att förhandla.

Possible 1,000-kilometer-long river running deep below Greenland's ice sheet
Computational models suggest that melting water originating in the deep interior of Greenland could flow the entire length of a subglacial valley and exit at Petermann Fjord, along the northern coast of the island. Updating ice sheet models with this open valley could provide additional insight for future climate change predictions.

pH-sensitive iridium complexes as catalytic anticancer compounds
Chemotherapy is defined as the use of chemicals to reach and damage cancer cells. On its way toward the tumor, the drugs can affect healthy cells, as well.

It might also contribute to a better understanding of the universe since iron oxides are observed in the emission spectra of stars.

A third of our waste comes from buildings. This one's designed for reuse and cuts emissions by 88%
Designing buildings so they can easily be taken apart and the materials reused provides a feasible and commercial pathway for minimizing waste and greenhouse gas emissions. Our research shows one such Curtin University building, the Legacy Living Lab in Fremantle, reduces construction waste and cuts emissions to almost a tenth of what a conventional building process would produce.
