The team has shown that its device delivers radiation doses to biological cells that are similar to doses created by much larger conventional proton-therapy systems. The researchers say that the technique could also be used to study ultrafast processes in biology and chemistry.2

If we were ever to do it: the thrill would be in getting to the end of the trip, to clearly view the stars from another sky, and eventually the soil of another earth.

In short, nitrogen vacancies are important building blocks for for quantum computers.

But there’s a problem. It’s not hard to make individual nanodiamonds but it is extremely difficult to arrange them next to each other so that the quantum information they store can be processed.

Their idea is to bind nanodiamonds together with the required nanometre precision using biological molecules such as DNA and protein. What’s more, they say they’ve demonstrated the technique for the first time.

No measure, despite how noble the intentions, will 100% protect us from our fellow humans, and comparisons to dangers from knives, cars and baseball bats obfuscates the issue at hand: the warping of the constitution to justify building personal arsenals (with no apparent responsibility to secure them), and the wealth of weapons manufacturers. Mr. LaPierre is a lobbyist, and like so many "chicken hawk patriots" conveniently missed his generations' opportunity to be a "good guy with a gun" and represent his country in Vietnam.

In physics, entropy is why there can be no such thing in nature as 100% efficiency or perpetual motion machines. Thus, no one political party, culture/race has, or should have a complete lock on the Oval Office and the Presidential Mansion (as it was once called).

And by some stretch of sanity, what would be gained if such inane, insane actors were actually successful in what could nakedly be called revolution and armed insurrection? The Pyrrhic ashes of anarchic victories are a poor foundation to rebuild a republic from.

• For starters: how about an ATF Director (not ONE since 2006)?
• Propose Conflict Resolution Skills classes to students and teachers K - 12.  Science teacher Ryan Heber essentially used that to talk a shooter down in California, diminishing casualties.
• Propose rebuilding infrastructure of state mental health services gutted by cuts - obviously, the "free market" has seen no value in filling this need.
• Propose universal background checks for all gun sales (including mental health screens).
• Propose registration of all legally purchased firearms and owning tax.
• Proposal: Digital Grip Recognition Biometric authorizing tech: you shoot it, you own it and the consequences.
• Propose owners spend up to $5,000.00 to secure home arsenals (preferably biometric safes).
• Propose owners liable $500,000.00 if stolen weapons are used in armed robbery.
• Propose owners liable $1,000,000.00 if stolen weapons are used in a murder.

In junior high, Tyson took to using his telescope on the roof of his apartment building. At the sight of a teenager fumbling with a mysterious object in the night, neighbors often thought they saw a thief and called the police, whom he would placate by offering a look through the lens.

In high school, Tyson won summer scholarships to study astrophysics in Africa, Utah, and Scotland. He rubbed elbows with astronaut Neil Armstrong and biochemist and sci-fi writer Isaac Asmiov. At 15 he was invited to give his first lecture, to an extension class at the City University of New York.

“It was as natural as breathing,” Tyson recalls. “I was just talking about what I knew, the way other boys talked about baseball cards.”

Frank Bash, professor emeritus of astronomy and former director of UT’s McDonald Observatory, supervised Tyson as a teaching assistant for Intro to Astronomy. “Neil had a natural gift for teaching,” Bash says. “After he taught, the students would beg for him back. He did crazy stuff—moonwalking in class.”

Doing the moonwalk for his students wasn’t a gag, Tyson says—it was a strategy. “If you’re only using words to communicate as a teacher, why show up?” he says. “Why not just type your notes? Teaching is a full-body performance. The moonwalk was all the rage in 1983, and the students loved it. It made the material work for them.”

Back in the lab, though, things weren’t going as well. Tyson wasn’t making progress on his dissertation, and professors encouraged him to consider alternate careers. He took the criticism hard, and he also faced racial discrimination on campus.

“I was stopped and questioned seven times by University police on my way into the physics building,” he says. “Seven times. Zero times was I stopped going into the gym—and I went to the gym a lot. That says all you need to know about how welcome I felt at Texas.”

"That which does not kill us makes us stronger."

Altering the course of climate change is a task that will take decades. It will require innovative new technologies and overhauls of the world’s energy, agricultural, and transportation infrastructure. We don’t suggest that you can reverse the warming trend over the next four years, or even that you will be able to significantly decrease carbon dioxide emissions. But with the help of the world’s best economic, technical, and scientific minds, you can formulate a policy that will show the nation—and the world—how we can begin to make the changes necessary to ensure that the concentration of carbon dioxide in the atmosphere stabilizes at a safe level. Indeed, it is critical that you do so.
