More than 2 billion cups of coffee are consumed worldwide, which means coffee beans used in all those lattes, espressos and mochas create a livelihood for millions of people worldwide.
Yet coffee plant production remains decidedly low-tech, and gimmick labels like "organic" and "fair trade" keep developing nations growing coffee stuck in the past. That has resulted in a "biennial effect" in yields, where years with high yields are often followed by years with low yields. The biennial effect makes it challenging for coffee breeders to compare yields from different varieties of coffee. Without accurate measures of yield, breeders cannot know which varieties of coffee would be most useful for farmers to grow.
It became a popular idea in pop culture, and therefore made its way into social psychology, after the 1964 case of Kitty Genovese, a 28-year-old woman who was raped and murdered in Queens, New York.
A New York Times reporter claimed 38 people witnessed it and though that turned out to be a fabrication, social psychologists Bibb Latané and John Darley formalized it as a phenomenon and numerous other social psychologists claimed to replicate it. But the real world has debunked it.
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.
They hoped to gain a deeper understanding of the political motivations of LGBTQ people and identify sexual, gender and queer identity gaps in liberalism.
That means male gametes may safely travel in space.
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.
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.
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.
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.
That is bringing us near European levels of science denial.
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.
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 new paper in JAMA Pediatrics correlates US immigration policy to adverse mental health outcomes in kids who are not immigrants at all - but their parents were.
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.
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.
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.
Greenland's Summer Melt Starts Early In June - But Winter Snowfall Increases In Warming World - How Does This Affect Sea Level?
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.
