Human Blood Cells can be directly Reprogrammed into Neural stem cells


Stem cells are considered to be the all-rounders of our tissues: they can multiply indefinitely and then — if they are pluripotent embryonic stem cells — generate all conceivable cell types.

Scientists from the German Cancer Research Center (DKFZ) and the stem cell institute HI-STEM* in Heidelberg have succeeded for the first time in directly reprogramming human blood cells into a previously unknown type of neural stem cell. These induced stem cells are similar to those that occur during the early embryonic development of the central nervous system. They can be modified and multiplied indefinitely in the culture dish and can represent an important basis for the development of regenerative therapies.

A Big Space Crash Likely made Uranus Lopsided


This image made from video provided by Durham University astronomy researcher Jacob Kegerreis shows a computer simulation generated by the open-source code SWIFT that depicts an object crashing into the planet Uranus. Kegerreis says the detailed simulations show that the collision and reshaping of Uranus 3 billion to 4 billion years ago likely caused the massive planet to tilt about 90 degrees on its side.

Uranus is a lopsided oddity, the only planet to spin on its side. Scientists now think they know how it got that way: It was pushed over by a rock at least twice as big as Earth...

Exposure to Cannabis Alters the Genetic Profile of Sperm


“There’s something about cannabis use that affects the genetic profile in sperm. We don’t yet know what that means, but the fact that more and more young males of child-bearing age have legal access to cannabis is something we should be thinking about.”
— Scott Kollins, Ph.D.

Whether genetic changes can be reversed or are passed on to children is still unknown. New research from Duke Health suggests men in their child-bearing years should also consider how THC could impact their sperm and possibly the children they conceive during periods when they’ve been using the drug...

Lean Electrolyte design is a game-changer for Magnesium Batteries


Directing Mg-Storage Chemistry in Organic Polymers toward High-Energy Mg BatteriesJoule, 2018; DOI: 10.1016/j.joule.2018.11.022

Chloride-free electrolyte and organic cathode boosted energy density, stability. Researchers from the University of Houston and the Toyota Research Institute of America have discovered a promising new version of high-energy magnesium batteries, with potential applications ranging from electric vehicles to battery storage for renewable energy systems.

The battery, reported Dec. 21 in Joule, is the first reported to operate with limited electrolytes while using an organic electrode, a change the researchers said allows it to store and discharge far more energy than earlier magnesium batteries...
