Blood vessels on a 3D printer & Dark matter theory may be wrong

[EnglishLady]

Two interesting news reports (well I think so LOL )



Dwarf galaxies suggest dark matter theory may be wrong

Scientists' predictions about the mysterious dark matter purported to make up most of the mass of the Universe may have to be revised.

Research on dwarf galaxies suggests they cannot form in the way they do if dark matter exists in the form that the most common model requires it to.

That may mean that the Large Hadron Collider will not be able to spot it.

Leading cosmologist Carlos Frenk spoke of the "disturbing" developments at the British Science Festival in Bradford

Artificial blood vessels created on a 3D printer

Artificial blood vessels made on a 3D printer may soon be used for transplants of lab-created organs.

Until now, the stumbling block in tissue engineering has been supplying artificial tissue with nutrients that have to arrive via capillary vessels.

A team at the Fraunhofer Institute in Germany has solved that problem using 3D printing and a technique called multiphoton polymerisation.

The findings will be shown at the Biotechnica Fair in Germany in October

They should use a 3D printer to print dark matter. It would solve a lot of problems, answer a lot of questions, and they could take it and show it to the Large Hadron Collider.

On a side note, this is how science actually works, where observation and experiment can often require the theory to be modified to fit the observations, unlike the junk science of Global Warming and Climate change, where the computer models and observations are altered to fit the theory. <snort>
