for “long” distances, such as between a CPU and memory, using photons instead of electrons could increase computing speeds while reducing energy consumption and removing heat from the system. Whereas electrons must transmit data serially, 1 electron after the other, optical signals can transmit data on many channels at once as fast as physically possible—the speed of light.

Where Do New Genes Come From?
some “orphan genes” with no obvious ancestors evolve out of junk DNA, contrary to old assumptions.

several genes that were present in only 1 or 2 species and not others, suggesting that these genes weren’t the progeny of existing ancestors. Begun proposed instead that random sequences of junk DNA in the fruit fly genome could mutate into functioning genes.
COVID-19 Inflammation
More therapeutic ideas for Covid-19: too much inflammation?
But if overstimulation of the immune response really is the problem, this approach could be just what’s needed.
COVID-19 Antibody Update
having some sort of “immunological passport” will be a complicated process, 1 that might not clear as many people as 1 would hope.
COVID-19 HIPPA scapegoating
It is true that HIPAA rules are (often overly) strict, and that does limit what healthcare providers can share, but this seems like trying to pin a false HIPAA violation on what is actually embarrassing whistleblowing in the midst of a pandemic.
Science vs. COVID-19
The website ingests all of the scientific papers about COVID-19 and analyzes it overnight. Our software classifies the papers into the top-level COVID-19 research categories. It extracts out all of the key authors and their affiliations, and extracts and defines the 1000s of jargon terms that exist in the literature.
Ventilators are overused
Many patients have blood oxygen levels so low (70%) they should be dead, but they’re not, so intubation may be the wrong thing to do.
Does Time Really Flow?
Gisin used intuitionist math to formulate an alternative version of classical mechanics, one that makes the same predictions as the standard equations but casts events as indeterministic — creating a picture of a universe where the unexpected happens and time unfolds.
Sewage Surveillance
In the past, local governments have been wary of wastewater surveillance, citing concerns about privacy.
more needless stupidity. let’s hope this becomes a normal thing.
SARS-CoV-2 RNA concentrations were a 7-day leading indicator ahead of compiled COVID-19 testing data and led local hospital admissions data by 3 days.
COVID-19 Response
this is a good mix of distributed innovation with some central vetting.
