Bystander apathy is a social psychological construct where it is believed that someone who sees a victim is less likely to offer help when other people are present. They say it is proportional to the number of bystanders, the more people around not helping the less likely anyone will help.

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.

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.
