Contrary to the long-held view that semen can only act as a way to transmit HIV-1 from men to women, scientists at The Wistar Institute and the University of Puerto Rico found that frequent and sustained semen exposure can change the characteristics of the circulating and vaginal tissue immune cells that are targets for infection, reducing the susceptibility to a future infection.
This finding, published in the journal Nature Communications, also provides a potential explanation as to why a small number of female sex workers worldwide continue to test negative for infection despite continuous high-risk sexual activity.

The number of Americans who “super commute” (travel 90 minutes or more to work each day, each way) is on the rise.
 
According to county-level data compiled by Apartmentlist.com from 2005 to 2017, the number of "super commuters" grew by 32%. That is more than triple the 9% growth rate for those with commutes shorter than 90 minutes.

"Vous regardez la télé, ce ne sont que des débats. Que va dire le président de la République ?  8 émissions. Une fois qu'il a parlé, qu'est-ce qu'il a dit ? On répète ce qu'il vient de dire... Ils nous prennent pour des cons quoi". "On ne peut plus rouler vite", se lamente aussi le chanteur, avant de s'en prendre aux chaussées qui rétrécissent. "La vie est moins souple, moins détendue que dans les années 80", résume-t-il.

Another big issue with what passes for modern-day wellness is that it creates the impression that everyone is happy all the time and that you should be, too.
But like selective sharing on social media, this is not the reality of being human.
 
In 2010, researchers from Brigham Young University completed a comprehensive study that followed more than 300,000 people for an average of 7.5 years and learned that the mortality risks associated with loneliness exceeded those associated with obesity and physical inactivity and were comparable to the risks of smoking.
 
Better than a fit mindset is a development mindset, in which you understand that passion takes time to emerge, thus lowering the bar for further engagement in something from “this is perfect” to “this is interesting.”
 
An app called Track Your Happiness has allowed thousands of people to report their feelings in real time.
The main finding: the more present and fully engaged you are with what’s in front of you, the happier you’ll be. It’s amazing how much just one or two blocks of undistracted work per day can do to improve your mood.

What won’t lead to spirituality and true well-being?
Trying to find meaning in all the stuff that modern-day wellness implicitly and explicitly promotes, such as beauty, wealth, antiaging, and sex appeal.

Young people today commit crimes at historically low rates and have attended college at historically high rates.
They have done everything right, sprinting at full speed while staying between the white lines, and their reward for historic conscientiousness is this: less ownership, more debt, and an age of existential catastrophe.
The typical Millennial awakens many mornings to discover that some new pillar of the world order, or the literal world, has crumbled overnight.
And while she is afforded little power to do anything about it, society has outfitted her with a digital megaphone to amplify her mordant frustrations.
Why in the name of family, God, or country would such a person lust for ancient affiliations? As the kids say, #BurnItAllDown.

As the older working class and younger generations struggle to renegotiate their attachments to faith, family, and community, they face similar challenges with regard to their mental health.
Anxiety, depression, and suicidality have increased to unprecedented levels among young people.
Meanwhile, deaths from drugs and suicide—so-called deaths of despair, which are concentrated in the white working class—have soared in the past two decades, recently reaching the highest levels ever recorded by the federal government.
Across generations, Americans seem to be suffering from, and dying of, new levels of loneliness in an age of crumbling institutions.

Concerns over how advances in AI will impact jobs aren't new.
Tesla and SpaceX CEO Elon Musk last month said AI could make many jobs "pointless."
One report earlier this year found that robots could replace humans in a quarter of US jobs by 2030.
