Science 2.0

Throughout human history, humans have artificially selected food. The sweeter, the better. When agriculture came into being, such genetic engineering became commonplace. A banana we eat today has nothing in common with one of a few hundred years ago. At one time we couldn't consume corn at all.

That evolutionary legacy, we once didn't have confidence when our next meal might be, is still evident. Sweet foods sell well and science has made them affordable; so affordable we have the opposite of the starvation problem poor people faced in the past.

It was said there was a 'rainbow wave' of LGBTQ voters after the Trump presidency and a new survey analysis set out to find what makes them tick.  To do so, authors distilled results a nationally representative sample of U.S. adults collected by Survey Sampling International after the November 2018 polls.

They hoped to gain a deeper understanding of the political motivations of LGBTQ people and identify sexual, gender and queer identity gaps in liberalism.

Work presented today at European Society of Human Reproduction and Embryology meeting showed said that a lack of difference in a range of sperm characteristics observed in frozen sperm samples exposed to microgravity and those maintained in ground conditions.

That means male gametes may safely travel in space.

If revenue numbers are true, gun manufacturers don't like when Democrats are in the White House. During the Clinton and Obama administrations gun sales did quite well, because Democrats are perceived by Republicans as more inclined to ban things and people who may not have been motivated to buy guns did, because they worried about bans.

Yet it may not be Democrats causing an uptick in purchases, it could be media making the public think mass shootings will cause Democrats to ban them.

Vitamin D helps keep bones strong and some diseases at bay. During the summer months, people are able to get about 90 percent of their daily vitamin D requirements through exposure to sunlight, but that is not the case during a northeast winter. 

The remainder is often obtained through food. Milk, for example, if fortified with vitamin D because children drink it and that keeps them healthy. Chicken eggs also provide vitamin D and since the nutrition fad has swung away from linking eggs to heart attacks it may be possible to give those affordable protein sources a vitamin boost.

Cities with a higher incidence of racist tweets showed more actual hate crimes related to race, ethnicity, and national origin, according to an analysis of the location and linguistic features of 532 million tweets published between 2011 and 2016.

A machine learning model identified and analyze two types of tweets: those that are targeted (directly espousing discriminatory views) and those that are self-narrative (describing or commenting upon discriminatory remarks or acts) and then the team compared the prevalence of each type of discriminatory tweet to the number of actual hate crimes reported during that same time period in those same cities.

When choosing a halal holiday, Muslim travel destinations are based on more than the location and the hotel. They also factor in Islamic religious values, such as Iman (faith) which may mean halal food, segregated facilities for men and women, prayer facilities and avoiding haram - things forbidden or proscribed by Islamic law.

Though the presence of Russian influence in social media during the 2016 election was hyped unrealistically (more damaging was their funding of activism against U.S. food and energy, designed to help them compete in Europe) the Federal Election Commission is perceived as being lax in digital advertising.

Because they gave exemptions to both Facebook and Google. A new paper shows how they were able to avoid disclosing who paid for advertisements related to the election.

No one admits to being swayed by celebrities, Facebook groups, or media coverage, but their impact is clear. Whereas 10 years ago vaccine denial was only prominent among wealthy elites on the west coast, a new The Harris Poll paid for by the American Osteopathic Association says that 45 percent of American adults admit something has caused them to doubt vaccine safety.

That is bringing us near European levels of science denial.

"Lag" is a common term for the latency in human-computer interactions caused by various factors related to the environment and performance of the devices, networks, and data processing.

There is no question it impacts the user's performance, and that impacts long-term usability, as the success of "Anthem" versus games like "Fortnite" show.

Math and science students do better who take music courses score significantly better on exams than their non-musical peers, and so do all students, according to a recent paper.

This is a hot topic in education. Some argue that vocational schools should make a comeback, and that students interested in math and science should focus on that rather than music, the way musicians practice rather than taking more science classes, but a look at 112,000 Canadian students shows it's not a two-way street. Some will do more art or music and not benefit from more STEM courses, perhaps because they already do fine. But STEM students benefit from arts.

A statistical correlation showed nearly a 50 percent increased risk of dementia among patients aged 55 and over who had used strong anticholinergic medication to contract and relax muscles  daily for three years or more. 

Anticholinergic drugs work by blocking acetylcholine, a chemical that transmits messages in the nervous system and is prescribed to treat a variety of conditions, including chronic obstructive pulmonary disease, bladder conditions, allergies, gastrointestinal disorders and symptoms of Parkinson's disease. Though they can have short-term side effects, including confusion and memory loss, there has been no scientific evidence that long-term use increases the risk of dementia.

If you have a large picture and you want people to focus on certain aspects of it, you frame it in such a way the eyes are drawn to it. 

It's no different in media. Though journalists try to be objective each news outlet has self-selection bias, determined by advertisers and subscribers. If you are going to be a journalist at Fox News or the New York Times, there will be a hidden values test you must pass, even if editors and hiring groups are not aware they do it.

While no one knows that causes posttraumatic stress disorder (PTSD), because it is a blanket term for anything that can be deemed "trauma", one thing is clear: United States Veterans seeking treatment for PTSD as a population are at increased statistical risk of death compared with the general public. 

Veterans with PTSD are twice as likely to die from suicide, viral hepatitis due to drug use, and even accidents than the general population.

Another post to help people scared of the Iran - US situation. For most people the personal risk is zero. Short summary: Trump seems to have ordered a strike on selected Iranian facilities - and then backed down at the last minute after attempting a diplomatic phone call with Iran and talking to a couple of Iranian officials. He says he did it becaue he was told at the last minute that it would kill about 150 people in Iran which is not proportionate for shooting down an unarmed drone.

Such a strike would be a major thing for him to do and he is being widely criticized by the democrats. Others such as Germany’s Angela Merckel are taking a positive line, saying they welcome reports that he decided against it.

Short summary: This is another climate change story hitting the news which is nothing to worry about. The early melt this summer is likely to mean a significant net loss but not unusual, similar to 2012 which also had an early melt. This is not a concern, it is just natural variability. It is balanced to some extent by snowfall in winter, which also was low this year. However, last year the amount of ice in Greenland actually increased due to large amounts of snowfall in the winter of 2017 - 8.

The long term trend continues at about 0.72 mm a year increase in sea level due to Greenland ice melting at present. This may increase later in the century. This is all expected and nothing to worry about, the IPCC projections still apply.

In synergy with the third season of the hit Netflix series "Stranger Things", Burger King is selling upside-down Whoppers starting today, retro 1980s packaging included.

If you are not familiar with the show, and without too many spoilers, "Stranger Things" is a science fiction-horror show revolving around teens in the 1980s. If you are not familiar with Burger King, I suppose it's simple enough to say they sell hamburgers. And want to catch up to rival McDonald's.

RR Auction in Boston has a selection of pretty interesting Apollo program stuff, but you have to bid before 7PM.

This is the perfect time to sell, the 50th anniversary of the moon landing is a month away, so it may not be the perfect time to buy. I have made a decent amount of money selling key comics a month before the next Marvel movie release and buying identical or better copies a year later from people who made impulse buys.

Up for grabs is an American flag flown into orbit on Apollo 11, signed by Command Module pilot Michael Collins. There is also a burn chart page from the flight plan that went into orbit on the Columbia Command Module, signed by both Collins and Buzz.
