Our auditory system is able to detect sounds at an implicit level. The brain can distinguish between even very similar sounds, but we do not always recognize these differences. A new study demonstrated using sound perception during passive listening; when the subject is not trying to explicitly hear the differences.

The result was that the human brain unconsciously distinguishes between even very similar sound signals during passive listening.  
Although unconventional, the ideas of Gregory Ryskin on vacuum energy sound interesting to me, so I invited him to share them with you in this guest post. 

Ryskin's physics journey began with fluid dynamics, first in Russia, then in the US, at Caltech. Later, the flow of complex fluids, such as polymer solutions or liquid crystals. Then Brownian motion and Markov processes. In 2000, he became interested in geology and geophysics, particularly in the causes of mass extinctions and the origin of the Earth’s magnetic field. His current research is focused on cosmology. His academic home is Northwestern University, Department of Chemical and Biological Engineering.
The text below is Gregory's.

The rise of the omicron variant has caused havoc around the world, just as the emergence of the delta and alpha variants did before. A pattern has emerged, with the world scrambling to respond to a new form of the coronavirus every six or so months. How can we reduce the risk of new variants appearing again and again?

Firstly, let’s consider how they emerge. A virus reproduces by making copies of itself. Every time it replicates, there’s a tiny chance that an error occurs in the copying of the virus’s genetic sequence.

We may be our own worst critics, but America continues to lead the world in science, science literacy, and science policy. Anyone who has tried to navigate science policy in Europe knows how bad it can get when the discourse is hijacked by government-funded environmental groups who use taxpayer money to prevent sane efforts at progress for European taxpayers.

Compared to Europe, American scientists have it good.

Check out your birth certificate and surely you’ll see a designation for sex. When you were born, a doctor or clinician assigned you the “male” or “female” label based on a look at your genitalia. In the U.S., this has been standard practice for more than a century.

But sex designation is not as simple as a glance and then a check of one box or another. Instead, the overwhelming evidence shows that sex is not binary. To put it another way, the terms “male” and “female” don’t fully capture the complex biological, anatomical and chromosomal variations that occur in the human body.

Utility customers in California are being exploited by a special class of grifters. Those who live in apartment buildings or rental homes or live in poor neighborhoods are forced by law to subsidize million-dollar solar installations on homes in Malibu.

The poor are exploited in the form of a direct rebate which depletes funds that could be used for social services for all Californians, plus a special tax levied on their utility bills. It not only pays wealthy people to install solar panels, it pays them to sell any electricity back to the power company on bright days for the same price they buy it at night.
The ongoing SARS-CoV-2 pandemic and new mutations in viral genetic sequences have made "variant" part of the cultural lexicon, because they can have significant impacts on the virus’s transmissibility and the damage it causes. 

Researchers have long been concerned that could happen in the HIV-1 virus, which has been mitigated thanks to safer sex practices and modern science but still affects 38 million people worldwide.
This is the third coronavirus pandemic of this century, after SARS and MERS, and due to that many forget that influenza is a chronic killer, 40-60,000 deaths in America alone each year. To mitigate those effects, there is a seasonal flu vaccine. Each year researchers model how they expect the virus to mutate and then they create a vaccine based on that. Some years are more successful than others but if people do get the flu, effects will be reduced.
Our life on earth began in water but how did it 'evolve'?

To get an understanding of the link between the chemistry of carbon and water, scientists can track the various forms, or isotopes, of its constituent hydrogen and oxygen atoms over the history of the universe, like a giant treasure hunt.

Recently, researchers from the CNRS, Paris-Saclay University, the French Alternative Energies and Atomic Energy Commission (CEA), and the University of Pau and the Pays de l’Adour (UPPA), with support from the Muséum National d’Histoire Naturelle (MNHN), have followed the trail of the isotopic composition of water back to the start of the solar system, in the inner regions where Earth and the other terrestrial planets were formed.
Implicit Racism tests say you are a bigot, it is only a question of how much. Social justice warriors and others in the humanities insist that even a field like astronomy is inevitably a reflex of the power of the socially privileged.

Given that science is always under fire from all sides, is there a way for science to guide technology on ways to help the public find trustworthy sources without 'Who Watches The Watchmen' and 'Follow The Money' claims polluting the discourse?
