At about 10:54 p.m. EDT, Parker Solar Probe surpassed 153,454 miles per hour — as calculated by the mission team — making it the fastest-ever human-made object relative to the Sun. This breaks the record set by the German-American Helios 2 mission in April 1976.

Parker Solar Probe will repeatedly break its own records, achieving a top speed of about 430,000 miles per hour in 2024.

Two new studies by researchers in Tel Aviv University and Harvard University on the subject were published in the journal Nature Biomedical Engineering on Monday.

Organs-on-a-chip were first developed in 2010 at Harvard University. Then, scientists took cells from a specific human organ — heart, brain, kidney and lung — and used tissue engineering techniques to put them in a plastic cartridge, or the so called chip. Despite the use of the term chip, which often refers to microchips, no computer parts are involved here.

Drexel University researchers have reported a method to quickly identify and label mutated versions of the virus that causes COVID-19. Their preliminary analysis, using information from a global database of genetic information gleaned from coronavirus testing, suggests that there are at least six to 10 slightly different versions of the virus infecting people in America, some of which are either the same as, or have subsequently evolved from, strains directly from Asia, while others are the same as those found in Europe.

First developed as a way of parsing to get a snapshot of the mix of bacteria, the genetic analysis tool teases out patterns from volumes of genetic information and can identify whether a virus has genetically changed. They can then use the pattern to categorize viruses with using tags called Informative Subtype Markers (ISM).

Applying the same method to process viral genetic data can quickly detect and categorize slight genetic variations in the SARS-CoV-2, the novel coronavirus that causes COVID-19, the group reported in a paper recently posted on the preliminary research archive, bioRxiv. The genetic analysis tool that generates these labels is publicly available for COVID-19 researchers on GitHub.

In particle physics, we try to understand reality by looking for smaller and smaller building blocks. But what if that has been the wrong philosophy all along?

In standard use, the S-matrix can be calculated if you understand the forces in the interaction region – for example, in the nucleus of an atom. But what if you don’t know those internal interaction forces? Heisenberg sought a way to ignore that internal structure and, rather, treat the S-matrix as fundamental. The S-matrix was to become the physics of the interaction, rather than an emergent property of more fundamental, internal physics. Heisenberg’s made some progress in the 40s, but the approach came into its own 20 years later when the atomic nucleus refused to give up its mysteries.
