Light pollution can suppress melatonin production in humans and animals.Melatonin synchronizes the day-night-rhythm in animals and humans. It adjusts the circadian clocks of cells, tissues and organs, and regulates other seasonal processes like reproduction.

I would love to be able to see the true darkness of the sky at night the way our ancestors did… Where I live stars are kinda rare.

Check out darksky.org if light pollution interests you. Their mission includes promoting smarter and healthier lighting design as well as protecting the night sky.

Outdoor lighting designer here:

“…and outdoor lighting on the order of 150 lux.”

No. At least not in the US. Not from streetlights. Typically, lighting designers will apply S/P ratios to compare different light sources in a mesiopic environment, LEDs benefit from this greatly.

While light pollution can be traced to conditions like suppression of melatonin, the amount is immaterial when compared to the effects of computers and personal electronic devices.

It’s important for kids to sleep in dark rooms. If you have a cranky kids try getting rid of the nightlight

And it goes the other way too. Blind people often have horrendous circadian rhythm problems.

True meanings of words of emotion get lost in translation, study finds. The way people understand terms such as “anger” or “love” differs between languages, and analysis finds there may be no universal concepts for some emotions.

Anyone who speaks two or more languages will tell you translations are only approximations.

There was similar studies done regarding language and how it relates to colours and found that language shapes the ability to recognize certain colours.

I even remember reading a study a while back about, I believe it was an Australian Aboriginal language, where instead of saying ‘left or right’ everything was done by cardinal directions so if your arm was facing north it would be your ‘north arm’ or your ‘west leg’. It meant that those people were constantly aware of the cardinal directions in a way the researchers hadn’t originally thought possible.

Fascinating stuff.

Language seems to permeate every aspect of how we perceive the world and ourselves and we don’t even realize it until you start looking at how other people use language to make sense of things. It makes you wonder what emotions or perceptions or emotions we’re simply not aware of because we haven’t found the tools to describe it yet.

InsertWittyJoke

The idea is logically contradictory: how can you know that there are no “universal concepts for some emotions” without knowing conceptually what emotions you are talking about? It might require more words in one language to express what is captured by fewer words in another language. But that doesn’t mean there is “no universal concept.”

>Our next analysis investigated whether geographic proximity predicted the pattern of variation in emotion semantics across language families. We tested this hypothesis by correlating the geographic proximity of language families (via the latitude and longitude coordinates of their languages) with their pairwise ARI values. As predicted, language families with higher pairwise ARI values were in closer geographic proximity, both in the full sample of our ARI comparisons, r(188) = −0.26, p < 0.001, and in the smaller permutation-robust sample, r(55) = −0.29, p = 0.03 (Fig. 3). These associations suggest that emotion semantics do not vary randomly; their variation is tied to the cultural evolutionary relationship between language families.

I’d very much like someone to comment on those ARI values.

Liberals are more accepting of scientific facts — and nonfactual statements, suggests a new study (n=270). Whereas more conservative persons may be unduly skeptical, more liberal persons may be too open and therefore vulnerable to inaccurate information presented in a manner that appears scientific.

> “One significant caveat is the limited sample in this study. We only examined undergraduate students from one university, so the findings are not as generalizable. Therefore, one major question remaining is the question of whether or not these findings generalize to the public at large,” Medlin explained.

Pretty misleading title there.

chuckknucka

What is “a manner that appears scientific”? An article in an online “source” no one’s heard of with a bunch of big words?

zeno0771

Can we stop having studies divide people on a binary politcal scale. There is a huge range of political beliefs that exist outwith the binary. I understand this study was done in the US which exists in, essentially, a two party system but still. I feel they should classify the system by party if they wish to run the study as a binary.

> In the study, 270 college students were asked to rate their agreement with a series of scientific facts and nonfactual statements. Scientific facts included statements such as “A typical cumulus cloud weighs about 1.1 million pounds,” while nonfactual statements included common false beliefs such as “Humans only use about 10% of their brain.”

I wonder if they were “given don’t know”, “unsure” or “need more information” as options or if it was just agree or disagree to varying extents?

I also find myself wondering how many of the participants simply wanted to appear smart or knowledgeable?

Declaration of Independence

IN CONGRESS, July 4, 1776.

The unanimous Declaration of the thirteen united States of America, When in the Course of human events, it becomes necessary for one people to dissolve the political bands which have connected them with another, and to assume among the powers of the earth, the separate and equal station to which the Laws of Nature and of Nature’s God entitle them, a decent respect to the opinions of mankind requires that they should declare the causes which impel them to the separation. We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.— That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed,— That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness. Prudence, indeed, will dictate that Governments long established should not be changed for light and transient causes; and accordingly all experience hath shewn, that mankind are more disposed to suffer, while evils are sufferable, than to right themselves by abolishing the forms to which they are accustomed. But when a long train of abuses and usurpations, pursuing invariably the same Object evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Government, and to provide new Guards for their future security.— Such has been the patient sufferance of these Colonies; and such is now the necessity which constrains them to alter their former Systems of Government. The history of the present King of Great Britain is a history of repeated injuries and usurpations, all having in direct object the establishment of an absolute Tyranny over these States. To prove this, let Facts be submitted to a candid world. He has refused his Assent to Laws, the most wholesome and necessary for the public good. He has forbidden his Governors to pass Laws of immediate and pressing importance, unless suspended in their operation till his Assent should be obtained; and when so suspended, he has utterly neglected to attend to them. He has refused to pass other Laws for the accommodation of large districts of people, unless those people would relinquish the right of Representation in the Legislature, a right inestimable to them and formidable to tyrants only. He has called together legislative bodies at places unusual, uncomfortable, and distant from the depository of their public Records, for the sole purpose of fatiguing them into compliance with his measures. He has dissolved Representative Houses repeatedly, for opposing with manly firmness his invasions on the rights of the people. He has refused for a long time, after such dissolutions, to cause others to be elected; whereby the Legislative powers, incapable of Annihilation, have returned to the People at large for their exercise; the State remaining in the mean time exposed to all the dangers of invasion from without, and convulsions within. He has endeavoured to prevent the population of these States; for that purpose obstructing the Laws for Naturalization of Foreigners; refusing to pass others to encourage their migrations hither, and raising the conditions of new Appropriations of Lands. He has obstructed the Administration of Justice, by refusing his Assent to Laws for establishing Judiciary powers. He has made Judges dependent on his Will alone, for the tenure of their offices, and the amount and payment of their salaries. He has erected a multitude of New Offices, and sent hither swarms of Officers to harrass our people, and eat out their substance. He has kept among us, in times of peace, Standing Armies without the Consent of our legislatures. He has affected to render the Military independent of and superior to the Civil power. He has combined with others to subject us to a jurisdiction foreign to our constitution, and unacknowledged by our laws; giving his Assent to their Acts of pretended Legislation: For Quartering large bodies of armed troops among us: For protecting them, by a mock Trial, from punishment for any Murders which they should commit on the Inhabitants of these States: For cutting off our Trade with all parts of the world: For imposing Taxes on us without our Consent: For depriving us in many cases, of the benefits of Trial by Jury: For transporting us beyond Seas to be tried for pretended offences For abolishing the free System of English Laws in a neighbouring Province, establishing therein an Arbitrary government, and enlarging its Boundaries so as to render it at once an example and fit instrument for introducing the same absolute rule into these Colonies: For taking away our Charters, abolishing our most valuable Laws, and altering fundamentally the Forms of our Governments: For suspending our own Legislatures, and declaring themselves invested with power to legislate for us in all cases whatsoever. He has abdicated Government here, by declaring us out of his Protection and waging War against us. He has plundered our seas, ravaged our Coasts, burnt our towns, and destroyed the lives of our people. He is at this time transporting large Armies of foreign Mercenaries to compleat the works of death, desolation and tyranny, already begun with circumstances of Cruelty & perfidy scarcely paralleled in the most barbarous ages, and totally unworthy of the Head of a civilized nation. He has constrained our fellow Citizens taken Captive on the high Seas to bear Arms against their Country, to become the executioners of their friends and Brethren, or to fall themselves by their Hands. He has excited domestic insurrections amongst us, and has endeavoured to bring on the inhabitants of our frontiers, the merciless Indian Savages, whose known rule of warfare, is an undistinguished destruction of all ages, sexes and conditions. In every stage of these Oppressions We have Petitioned for Redress in the most humble terms: Our repeated Petitions have been answered only by repeated injury. A Prince whose character is thus marked by every act which may define a Tyrant, is unfit to be the ruler of a free people. Nor have We been wanting in attentions to our Brittish brethren. We have warned them from time to time of attempts by their legislature to extend an unwarrantable jurisdiction over us. We have reminded them of the circumstances of our emigration and settlement here. We have appealed to their native justice and magnanimity, and we have conjured them by the ties of our common kindred to disavow these usurpations, which, would inevitably interrupt our connections and correspondence. They too have been deaf to the voice of justice and of consanguinity. We must, therefore, acquiesce in the necessity, which denounces our Separation, and hold them, as we hold the rest of mankind, Enemies in War, in Peace Friends. We, therefore, the Representatives of the united States of America, in General Congress, Assembled, appealing to the Supreme Judge of the world for the rectitude of our intentions, do, in the Name, and by Authority of the good People of these Colonies, solemnly publish and declare, That these United Colonies are, and of Right ought to be Free and Independent States; that they are Absolved from all Allegiance to the British Crown, and that all political connection between them and the State of Great Britain, is and ought to be totally dissolved; and that as Free and Independent States, they have full Power to levy War, conclude Peace, contract Alliances, establish Commerce, and to do all other Acts and Things which Independent States may of right do. And for the support of this Declaration, with a firm reliance on the protection of divine Providence, we mutually pledge to each other our Lives, our Fortunes and our sacred Honor.

A ‘jackalope’ of an ancient spider fossil deemed a hoax, unmasked as a crayfish | They painted legs on it

> “These things are dug up by local farmers mostly, and they see what money they can get for them,” Selden said. “They obviously picked up this thing and thought, ‘Well, you know, it looks a bit like a spider.’ And so, they thought they’d paint on some legs – but it’s done rather skillfully. So, at first glance, or from a distance, it looks pretty good. It’s not till you get down to the microscope and look in detail that you realize they’re clearly things wrong with it. And, of course, the people who described it are perfectly good paleontologists – they’re just not experts on spiders. So, they were taken in.”

In case you’ve skipped the article, the hoax was not fabricated by the original researchers, but the local farmers who sold the fossil to them. Selden, one of the researchers who uncovered this hoax, says that it was reasonable that the original researchers could have been duped by the fabrication.

Some parents have noticed that their autistic children’s behavioral symptoms diminished after a fever. A new study from MIT and Harvard in mice found that an immune molecule sometimes produced during infection suppresses a small region of the brain’s cortex linked to social behavioral deficits.

These researchers are amazing! They put in the work to account for most coincidental correlations, granted it was only in mice. So, IL-17a is normally produced by pregnant women while they’re sick. Additionally, a massive study in Denmark found that women who got a viral infection during their first trimester, were 3x more likely to birth an autistic child. These researchers found that, in autistic-like mice, IL-17a was produced during inflammatory immune responses. This molecule, il-17a, wasn’t only given to the mice with social disorders, but those were the only ones that it showed any curative effects. It actually had the opposite affect on normal mice. They also increased the autistic-like mices’ body temperature(the phenomenon was originally noticed in feverish autistic kids), and it had no affect; indicating it was an immune response that had these affects. Furthermore they blocked the il-17a receptors, and the curative affects stopped.

Edit: I do not mean to insult individuals with autism. This study seems to indicate it’s only tiny part of the brain that is affected. If this is the case, autistic people are far closer to normal than most would think.

A completely separate study (n=19,238 individuals with autism in California) found *”conception in the winter season (December, January, and February) was associated with a 6% increased risk compared with summer.”*

Peak flu season in the US is December-March. There’s a lot of evidence to support this theory, so if you are pregnant/trying to get pregnant; a flu shot is a good idea.

For those asking about flu shots while pregnant. *It’s safe to get a flu shot during pregnancy. In fact, the Centers for Disease Control and Prevention and the American College of Obstetricians and Gynecologists recommend that all women who are pregnant during flu season get a flu shot, regardless of their trimester.*

Great. Now the idiots who think drinking bleach cures autism are going to be giving their kids infections to try to bring on fevers.

Uncle-Cake

What kind of “autstic behavior” are we talking about? Like severe, or more mild? Autism is way too wide and complicated to say it goes for “autism” all together, rather than just some forms of it that are on the spectrum. Also, I have some serious doubts about this being a actual thing that would work because it is just so complicated.

JaegerDread

My son has autism. When he was around 4 yo he could not speak in full sentences. While he had a high fever, he spoke in full sentences for the entire time he had a fever (lasted about 1 1/2 hrs). As his fever returned to normal he returned to not being able to talk in full sentences.

MsInquisitor

I look forward to seeing where this science leads!

It seems like a lot of comments know ‘everything there is’ when clearly this could lead to completely new information (source, potential cures, etc) it’s pretty wide open and people need to be a little more willing to see what’s uncovered.
