Edgar Allan Poe, The author, poet, editor, and literary critic, died in 1849 at age 40 in Maryland. He was chronically depressed, he had even tried to commit suicide using laudanum a year before his death.

But when he went to the hospital for the last time, having been found delirious and wearing a stranger's clothes, he hadn't been committing suicide, according to a heuristic look at his writing.
Merge is a controversial belief by some that human language faculty arose in humans through a single gene mutation, rather the evolving gradually.

This human burst of genetic exceptionalism is embraced by some linguists, such as Noam Chomsky, but the science community has doubts. The basis for Merge is that humans are genetically equipped with a unique cognitive capacity that specifically allows us to implement computations over hierarchically structured symbolic representations.
Sildenafil (viagra) is used to treat erectile dysfunction and is safe, with known side effects, but a few people have experienced light sensitivity and color vision impairment at the highest recommended dose.

That doesn't mean men who need it should stop taking it, the psychological consequences of erectile dysfunction are of more concern than side effects, which can include headache and blurred vision that disappear quickly. These occur because sildenafil was originally developed as a treatment for high blood pressure, and it also dilates blood vessels and relaxes smooth muscle in the penis, making it easier to achieve and maintain an erection. 
A recent study identified the coronavirus responsible for the pneumonia epidemic in the Hubei province of China and finds the bat-origin virus is related to other known pathogenic coronaviruses.

The 2019 coronavirus (CoV) causes fatal pneumonia that has claimed over 1,300 lives, with more than 52,000 confirmed cases of infection by mid-February, along with various impacts to the lives of the scholars who revealed the virus against the wishes of the Chinese government. 

We know the left and right side of our brain are specialized for cognitive abilities like language (left hemisphere) and the right hand. That functional lateralization is reflected by morphological asymmetry too. The left and right hemispheres differ subtly in brain anatomy, distribution of nerve cells, connectivity and even neurochemistry.

It can be seen on endocasts. Most humans have a combination of a more projecting left occipital lobe (located in the back of the brain) with a more projecting right frontal lobe.

Despite what you've heard, birds of a feather often don't flock together. In the real world, multiple bird species are often flying and feeding together. In the Amazon, 50 species may travel as a unit.

But are birds in these mixed flocks cooperating with one another or competing?

A new study suggests both. Just like a K-pop band such as BTS, Blackpink, or Red Velvet.
