Geoscientists have found the largest extraterrestrial diamonds ever discovered – a few tenths of a millimeter in size nevertheless – inside meteorites. Together with an international team of researchers, they have now been able to prove that these diamonds formed in the early period of our solar system when minor planets collided together or with large asteroids. These new data disprove the theory that they originated deep inside planets – similar to diamonds formed on Earth – at least the size of Mercury.

It is estimated that over 10 million asteroids are circling the Earth in the asteroid belt...

Quantum Entanglement realized between Distant Large Objects

Quantum entanglement realized between distant large objects
Light propagates through the atomic cloud shown in the center and then falls onto the SiN membrane shown on the left. As a result of interaction with light the precession of atomic spins and vibration of the membrane become quantum correlated. This is the essence of entanglement between the atoms and the membrane.

A team of researchers at the Niels Bohr Institute, University of Copenhagen, have succeeded in entangling two very different quantum objects. The result has several potential applications in ultra-precise sensing and quantum communication and is now published in Nature Physics.

Entanglement is the basis for quantum communication and quantum sensing...

Something old, something New Combine for Effective Vaccine against Parasitic Skin Disease

Scientists use CRISPR to edit structural gene in organism that causes leishmaniasis. Scientists are planning for Phase 1 human trials of a vaccine they developed by using CRISPR gene-editing technology to mutate the parasite that causes leishmaniasis, a skin disease common in tropical regions of the world and gaining ground in the United States.

“If you assure protection in the sand fly model, then you have a good shot at a real vaccine,” said Abhay Satoskar, a co-lead investigator of the work and professor of pathology and microbiology at The Ohio State University.

The team applied the new technology to the century-old Middle Eastern practice of le...
