Astronomers solve dark matter puzzle of strange galaxy — ScienceDaily

At present, the formation of galaxies is difficult to understand without the presence of a ubiquitous, but mysterious component, termed dark matter. Astronomers have measure how much dark matter there is around galaxies, and have found that it varies between 10 and 300 times the quantity of visible matter. However, a few years ago, the discovery of a very diffuse object, named Dragonfly 44, changed this view. It was found that this galaxy has 10,000 times more dark matter than the stars. Taken back by this finding, astronomers have made efforts to see whether this object is really anomalous, or whether something went wrong in the analysis of the observations. Now we have the answer.

An international team led by the Kapteyn Institute of the University of Groningen (the Netherlands), with participation by the Instituto de Astrofísica de Canarias (IAC) and the University of La Laguna (ULL), has found that

Pioneering new research has helped geologists solve a long-standing puzzle that could help pinpoint new, untapped concentrations of some the most valuable rare earth deposits.


A team of geologists, led by Professor Frances Wall from the Camborne School of Mines, have discovered a new hypothesis to predict where rare earth elements neodymium and dysprosium could be found.

The elements are among the most sought after, because they are an essential part of digital and clean energy manufacturing, including magnets in large wind turbines and electric cars motors.

For the new research, scientists conducted a series of experiments that showed sodium and potassium—rather than chlorine or fluorine as previously thought—were the key ingredients for making these rare earth elements soluble.

This is

For the new research, scientists conducted a series of experiments that showed sodium and potassium — rather than chlorine or fluorine as previously thought — were the key ingredients for making these rare earth elements soluble.

This is crucial as it determines whether they crystalise — making them fit for extraction — or stayed dissolved in fluids.

The experiments could therefore allow geologists

Tesla unveils battery puzzle pieces of smart material science, design, and manufacturing innovation

At its Battery Day event, Tesla unveiled its new 4680 battery cell developed in-house and the manufacturing process behind it.

The highly anticipated presentation went deep into details about all the different pieces of material science, design, and manufacturing innovations that it took to deliver the masterpiece of a puzzle that the automaker needed to put together to reduce battery costs by more than 50% in just 3 years…

Over the last few years, Tesla has been making a lot of moves related to batteries.

We are talking about buying companies like Maxwell and Hibar, and applying for patents on new technology, like a tabless battery cell and a cell to pack design.

While all these moves were mostly evaluated on their own merits, it wasn’t clear how all those things would fit together.

That’s exactly what Tesla demonstrated at its Battery Day.

Tesla explained how they have made major
