“RINGWOODITE is the most common mineral phase in the lower transition zone of the Earth’s mantle, at depths of 525 to 660 km. This ringwoodite crystal contains about 1% water. If the whole ringwoodite of the mantle contains this amount of water, it is estimated that there is almost three times as much water in the mantle as in all the oceans combined.” https://lnkd.in/dNuAzU2 View in LinkedIn

NUCLEOSYNTHESIS. “We see that for high metallicities (Z ≳ −1.5), a very large stellar progenitor (≳90M⊙) will be required to produce the massive black holes of the type that have been observed in mergers by LIGO. Lower metallicity populations require less extreme progenitors.” (LIGO = an observatory; M⊙ = unit of stellar mass in suns). https://lnkd.in/d8Jh7TB View in LinkedIn

ARTIFICIAL STABLE SILICON DOUBLE BOND. “While carbon–carbon double bonds are common in organic chemistry, at the heart of countless chemical transformations, silicon–silicon double bonds are much rarer. Despite silicon sitting just below carbon in the periodic table, silicon double bonds are much less stable than those involving carbon.” https://lnkd.in/dvvPbnC View in LinkedIn

SPEAKING SPIDER. “We're beginning to perhaps be able to speak the language of a spider.Scientists at the Massachusetts Institute of Technology have turned spider webs into music -- creating an eerie soundtrack that could help them better understand how the arachnids spin their complex creations and even how they communicate.” https://lnkd.in/dzyYUP5 View in LinkedIn

EXOTIC BEASTS. “We will discuss extremal and near extremal black holes. Extremal magnetic black holes are more stable than their electric counterparts, since unit charge magnetic monopoles are much heavier than electrically charged particles, and are thus harder to pair create. In addition, an electrically charged black hole can be neutralized in conductive medium, while a magnetically charged one cannot be neutralized with ordinary matter.” https://lnkd.in/dX6Fbwx View in LinkedIn
