From what Ive gathered, neutrinos arent technically actual particles. They are a bunch of properties, missing from the bundle of assumptions constituting the representation of certain particles.

What this might mean, in the terms Ive been working with recently, is that the are not entities in the sense that entities hold a certain self value, an ´awareness´ of what they are, by virtue of which they may relate to the universe, to being, to timespace as timespace.

Perhaps neutrinos arent enclosed in timespace, as they do not follow follow the protocol for being, which requires of a particle that it refers to itself in order to effectively refer itself to other energy. A neutrino would be existentially passive, requiring a specific context to be brought into existence, with all its quirks such as relativity.

Self vauing and other valuing should not be interpreted as a conscious act, but as the principle by which a wave or particle determines what it relates to, by which it is established as actual being. It is not an act in the sense of performing a movement, but more in the sense of gathering oneself, that action which in humans is just as elusive as it is necessary to perform any kind of action as an integer entity.

Y chromosome: Why men contribute so little

Scientists have practically obliterated the ultimate symbol of maleness in DNA, the Y chromosome, and believe they may be able to do away with it completely.
They condensed all the genetic information normally found on a mouse's Y chromosome to just two genes.
Their study, in the journal Science, showed the male mice could still father babies, albeit needing advanced IVF.
The team in Hawaii argues that the findings could one day help infertile men with a damaged Y chromosome.
DNA is bundled into chromosomes.
In most mammals, including humans, one pair act as the sex chromosomes.
Inherit an X and Y from your parents and you turn out male, get a pair of Xs and the result is female.
Two genes 'enough'
[You must be registered and logged in to see this image.]A human X and Y chromosome
"The Y chromosome is a symbol of maleness," lead researcher Professor Monika Ward told the BBC.
In mice, the Y chromosome normally contains 14 distinct genes, with some present in up to a hundred copies.

This is a great step forward in understanding basic biology”

Dr Chris Tyler-SmithWellcome Trust Sanger Institute
The team at the University of Hawaii showed that genetically modified mice with a Y chromosome consisting of just two genes would develop normally and could even have babies of their own.
Prof Ward commented: "These mice are normally infertile, but we show it is possible to get live offspring when the Y chromosome is limited to just two genes by using assisted reproduction."
The mice could only produce rudimentary sperm. But they could have offspring with the help of an advanced form of IVF, called round spermatid injection, which involves injecting genetic information from the early sperm into an egg.
The resulting pups were healthy and lived a normal lifespan.
Reproduction still possible
The two necessary genes were Sry, which kick-starts the process of producing a male as an embryo develops, and Eif2s3y, which is involved in the first steps of sperm production.
However, Prof Ward argues it "may be possible to eliminate the Y chromosome" if the role of these genes could be reproduced in a different way, but added a world without men would be "crazy" and "science fiction".
"But on a practical level it shows that after large deletions of the Y chromosome it is still possible to reproduce, which potentially gives hope to men with these large deletions," she added.
[You must be registered and logged in to see this image.]The father has hardly any Y chromosome
The genes which were discarded are likely to be involved in the production of healthy sperm.
Dr Chris Tyler-Smith, from the Wellcome Trust Sanger Institute, said: "This is a great step forward in understanding basic biology.
"But it is important to bear in mind that other mouse Y genes are needed for natural reproduction in mice and as the authors carefully emphasise, the conclusions cannot be applied directly to humans because humans don't have a direct equivalent of one of the key genes."
Dr Allan Pacey, a senior lecturer in andrology at the University of Sheffield, said: "This is a very interesting paper, trying to both unravel the genes responsible for sperm production and also shed light on the function of the Y-chromosome.
"The experiments are elegant and seem to show that in the mouse sperm production can be achieved when only two genes from the Y-chromosomes are present.
"Whilst this is of limited use in understanding human fertility, this kind of work is important if we are to unravel to complexities of how genes control fertility."

From basic (inter)activity a change occurs.
The different elements, patterns of fluidity, sometimes pulling towards, sometimes pushing away, as they relate, and chaos, randomness, produces an additional factor.

Actual abstract wrote:
Background
Social categorization and group identification are essential ingredients for maintaining a positive self-image that often lead to negative, implicit stereotypes toward members of an out-group. The medial prefrontal cortex (mPFC) may be a critical component in counteracting stereotypes activation.

Objective
Here, we assessed the causal role of the mPFC in these processes by non-invasive brain stimulation via transcranial direct current stimulation (tDCS).

Method
Participants (n = 60) were randomly and equally assigned to receive anodal, cathodal, or sham stimulation over the mPFC while performing an Implicit Association Test (IAT): They were instructed to categorize in-group and out-group names and positive and negative attributes.

Results
Anodal excitability-enhancing stimulation decreased implicit biased attitudes toward out-group members compared to excitability-diminishing cathodal and sham stimulation.

Conclusions
These results provide evidence for a critical role of the mPFC in counteracting stereotypes activation. Furthermore, our results are consistent with previous findings showing that increasing cognitive control may overcome negative bias toward members of social out-groups.

Quote :
A researcher in Russia has made more than 48 million journal articles - almost every single peer-reviewed paper every published - freely available online. And she's now refusing to shut the site down, despite a court injunction and a lawsuit from Elsevier, one of the world's biggest publishers.

For those of you who aren't already using it, the site in question is Sci-Hub, and it's sort of like a Pirate Bay of the science world. It was established in 2011 by neuroscientist Alexandra Elbakyan, who was frustrated that she couldn't afford to access the articles needed for her research, and it's since gone viral, with hundreds of thousands of papers being downloaded daily. But at the end of last year, the site was ordered to be taken down by a New York district court - a ruling that Elbakyan has decided to fight, triggering a debate over who really owns science.

"Payment of $32 is just insane when you need to skim or read tens or hundreds of these papers to do research. I obtained these papers by pirating them," Elbakyan told Torrent Freak last year. "Everyone should have access to knowledge regardless of their income or affiliation. And that’s absolutely legal."

journal subscriptions have become so expensive that leading universities such as Harvard and Cornell have admitted they can no longer afford them. Researchers have also taken a stand - with 15,000 scientists vowing to boycott publisher Elsevier in part for its excessive paywall fees.

"They feel pressured to do this," Elbakyan wrote in an open letter to the New York judge last year. "If a researcher wants to be recognised, make a career - he or she needs to have publications in such journals."

The site works in two stages. First of all when you search for a paper, Sci-Hub tries to immediately download it from fellow pirate database LibGen. If that doesn't work, Sci-Hub is able to bypass journal paywalls thanks to a range of access keys that have been donated by anonymous academics (thank you, science spies).

This means that Sci-Hub can instantly access any paper published by the big guys, including JSTOR, Springer, Sage, and Elsevier, and deliver it to you for free within seconds. The site then automatically sends a copy of that paper to LibGen, to help share the love.

Last year, a New York court delivered an injunction against Sci-Hub, making its domain unavailable (something Elbakyan dodged by switching to a new location), and the site is also being sued by Elsevier for "irreparable harm" - a case that experts are predicting will win Elsevier around $750 to $150,000 for each pirated article. Even at the lowest estimations, that would quickly add up to millions in damages.

But Elbakyan is not only standing her ground, she's come out swinging, claiming that it's Elsevier that have the illegal business model.

"I think Elsevier’s business model is itself illegal," she told Torrent Freak, referring to article 27 of the UN Declaration of Human Rights, which states that "everyone has the right freely to participate in the cultural life of the community, to enjoy the arts and to share in scientific advancement and its benefits".

She also explains that the academic publishing situation is different to the music or film industry, where pirating is ripping off creators. "All papers on their website are written by researchers, and researchers do not receive money from what Elsevier collects. That is very different from the music or movie industry, where creators receive money from each copy sold," she said.

Elbakyan hopes that the lawsuit will set a precedent, and make it very clear to the scientific world either way who owns their ideas.

"If Elsevier manages to shut down our projects or force them into the darknet, that will demonstrate an important idea: that the public does not have the right to knowledge," she said. "We have to win over Elsevier and other publishers and show that what these commercial companies are doing is fundamentally wrong."

To be fair, Elbakyan is somewhat protected by the fact that she's in Russia and doesn't have any US assets, so even if Elsevier wins their lawsuit, it's going to be pretty hard for them to get the money.
