Fig 1. In 2008, bioengineers at the University of Minnesota stripped rat hearts of cells using detergent — you can see the results of three trials here. This process left untouched the blood vessels, collagen, and various proteins that compose the heart’s physical structure.

Fig 2. The ghost heart is flushed with red dye to show that major and minor blood vessels were left intact.

Fig 3. A researcher injects the ghost heart with heart cells from newborn mice.

Fig 4. Researchers adjusted the environmental conditions to simulate natural conditions, meaning they provided oxygenate fluids, pressure, and an electrical stimulus. You can see the bioreactor schematic here.

GIF source here. Research paper here. Less technical writeup here. More videos from the lab itself here (Supplementary Movie 1 in particular is pretty awesome).

British researchers have created the ‘new black’ of the science world - and it is being dubbed super black.

The material absorbs all but 0.035 per cent of light, a new world record, and is so dark the human eye struggles to discern its shape and dimension, giving the appearance of a black hole.

Named Vantablack, or super black, it also conducts heat seven and half times more effectively than copper, and is ten times stronger than steel.

It is created by Surrey NanoSystems using carbon nanotubes, which are 10,000 thinner than human hair and so miniscule that light cannot get in but can pass into the gaps in between.

i found these little beakers at the antique store and have been using them as vases.

These lockets are anatomically correct. The locket is held shut by the trunk of the aorta, which acts as a snap. The chain attaches to the pendant through the superior vena cava and left pulmonary vein, causing the heart to hang slightly anterioinferiorly, just like our hearts!
