President Trump has seized on the response in the streets to police brutality against Black men and women to bolster his re-election campaign, employing provocative and sometimes incendiary language and images to incite his followers, demonize his opponents or both.
He has sought to conflate all protesters with the small minority of people who have looted stores, started fires and engaged in violence against police officers. He has blamed street unrest on Democratic mayors and governors and even former Vice President Joseph R. Biden Jr., his fall challenger.

Only one candidate incites his supporters to mayhem.
When Elizabeth Neumann went to work in counterterrorism in Donald Trump’s Department of Homeland Security, she thought she’d be focused on Islamic extremism, as she was in George W. Bush’s administration. But as the assistant secretary for counterterrorism and threat prevention at D.H.S., she soon realized that she had to take the threat of white-supremacist terrorism seriously.
“It was probably 2018 when we started to realize that this was not just a blip, that Charlottesville wasn’t just a blip,” she told me.
Even as she and her colleagues worked to understand how domestic white supremacists were being emboldened, there was a series of shocking attacks.
It all started with minor slips easily dismissed as “senior moments”
You forgot your keys. You called someone by the wrong name. The word you were looking for was on the tip of your tongue, but you couldn’t quite grasp it. You don’t feel any older, but you do feel yourself changing. Researchers agree this could be a sign of something more serious.
A study published in the British Medical Journal of January 2012 has concluded that age-related cognitive decline begins much earlier than expected: by our mid-40s. Even more distressing, this decline can progress at very unpredictable rates. Scientists have identified that acetylcholine, a key neurotransmitter, is responsible for forming new connections and strengthening neural pathways in the brain. In other words, it keeps your mind sharp. However, persistently low levels of this key neurotransmitter places you at risk. Without healthy levels of acetylcholine, the brain can physically shrink; at which point, the damage can be very difficult to repair.
And yet, we all know people of advanced age who seem immune to this cognitive decline.

Over one hundred years ago, on May 29, 1919, astronomers observed a total solar eclipse in an ambitious effort to test Albert Einstein’s general theory of relativity by seeing it in action. Essentially, Einstein thought space and time were intertwined in an infinite “fabric,” like an outstretched blanket. A massive object such as the Sun bends the spacetime blanket with its gravity, such that light no longer travels in a straight line as it passes by the Sun.
This means the apparent positions of background stars seen close to the Sun in the sky — including during a solar eclipse — should seem slightly shifted in the absence of the Sun, because the Sun’s gravity bends light. But until the eclipse experiment, no one was able to test Einstein’s theory of general relativity, as no one could see stars near the Sun in the daytime otherwise.
