# s-acad: or at least not as robust as they should be ...

<< This is the conclusion of Rigor Mortis, a wide-ranging critique of the modern biomedical research ecosystem by science journalist Richard Harris. He describes how a growing number of claims over the past decade that many published research findings are false, or at least not as robust as they should be, has led to calls for change, and the birth of a new discipline of metascience. >>

# s-astro: to peer into a black hole

<< By connecting a global array of radio telescopes together to form the equivalent of a giant Earth-sized telescope – using a technique known as Very Long Baseline Interferometry and Earth-aperture synthesis – scientists will peer into the heart of our Milky Way galaxy where a black hole that is 4m times more massive than our sun – Sagittarius A* – lurks. >>

# s-ethnomed: ancient flexible eat; self-medication among Neanderthals with aspirin and penicillin like

# s-gst: breaking a kind of time- symmetry to draw stabilities

<< Time crystals are hypothetical structures that pulse without requiring any energy — like a ticking clock that never needs winding >>

<< In 2012, Wilczek [Frank Wilczek] [..] wondered why symmetry never broke spontaneously in time and whether it would be possible to create something in which it did >>

<< These systems draw stability from random interactions that would normally disrupt other kinds of matter >>

<< As a report from the National Institute of Standards and Technology (NIST) released in April notes, this algorithm [to solve a problem called integer factorization] can be used to efficiently solve the mathematical problems at the heart of three of the most widely-used encryption approaches: Diffie-Hellman key exchange, RSA, and elliptic curve cryptography >>
