The Sound Of Settled Science

We are all mutants now…

We are all mutants. The 3bn pieces of DNA that make us who we are were long thought to be constant, chiselled in granite like a classical monument, with only tiny changes made here and there. Scientists used to believe that DNA mutations were largely harmful.
By the late 1990s and early 2000s, as the first sequences of the human genome came rolling in, researchers realised that their view of mutations was completely backwards. Instead of being rarities that almost inevitably harm health, mutations litter the human genome. The average human carries around 400 unique mutations, and most of us are none the worse because of them.
This challenged some basic tenets of genetics, as well as they ways that scientists and physicians interpreted genetic tests.

Bacteria Found in Alzheimer’s Brains

This may turn out to be signficant;

Researchers in the UK have used DNA sequencing to examine bacteria in post-mortem brains from patients with Alzheimer’s disease. Their findings suggest increased bacterial populations and different proportions of specific bacteria in Alzheimer’s, compared with healthy brains. The findings may support evidence that bacterial infection and inflammation in the brain could contribute to Alzheimer’s disease.

Stay tuned.

When the bosses said make it warm, “scientists” at NOAA, NASA and Hadley CRU asked, “How high?”

“Thus, it is impossible to conclude from the three published GAST data sets that recent years have been the warmest ever – despite current claims of record setting warming,” according to a study published June 27 by two scientists and a veteran statistician.
The peer-reviewed study tried to validate current surface temperature datasets managed by NASA, NOAA and the UK’s Met Office, all of which make adjustments to raw thermometer readings. Skeptics of man-made global warming have criticized the adjustments.

The Sound Of Settled Science

Liquid light.

New research published this week in the journal Nature Physics reveals that light can behave in an even stranger “superliquid” state, in which light particles flow around objects with no friction or viscosity at all. In this state, light exhibits the dramatic effect of “frictionless flow,” bending around obstacles with no ripples or swirls whatsoever. Interestingly, this effect can be observed at room temperature and ambient pressure.

What Would We Do Without Researchers?

RoundUp has long been considered a benign alternative to harsher weedkillers. After extensive reviews, most regulatory agencies–the US Environmental Protection Agency, the European Food Safety Authority, and those of many other nations–have come to the conclusion that it does not cause cancer. So when the International Agency for Research on Cancer (IARC), a division of the UN’s World Health Organization, declared RoundUp a probable carcinogen in 2015, there was an international outcry. Shortly after, 184 plaintiffs in California filed a legal case against Monsanto, saying that the company failed to warn them about the risks of its product. Since then, in a separate suit, hundreds more plaintiffs have claimed that RoundUp caused their cancers, citing the IARC’s findings as evidence.
About that evidence: According to a new Reuters investigation, Aaron Blair, the scientist who led the IARC’s review panel on glyphosate, had access to data from a large study that strongly suggested that Roundup did not cause cancer after all–but he withheld that data from the RoundUp review panel. Weirder still: Blair himself was a senior researcher on that study.

New York Times;

Fossils discovered in Morocco are the oldest known remains of Homo sapiens, scientists reported on Wednesday, a finding that rewrites the story of mankind’s origins and suggests that our species evolved in multiple locations across the African continent.
“We did not evolve from a single ‘cradle of mankind’ somewhere in East Africa,” said Philipp Gunz, a paleoanthropologist at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, and a co-author of two new studies on the fossils, published in the journal Nature. “We evolved on the African continent.”

Except for the space aliens currently in control of the Democratic Party.

Consensus;

The salt equation taught to doctors for more than 200 years is not hard to understand.
The body relies on this essential mineral for a variety of functions, including blood pressure and the transmission of nerve impulses. Sodium levels in the blood must be carefully maintained.
If you eat a lot of salt — sodium chloride — you will become thirsty and drink water, diluting your blood enough to maintain the proper concentration of sodium. Ultimately you will excrete much of the excess salt and water in urine.
The theory is intuitive and simple. And it may be completely wrong.
