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 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.
