Across Earth’s history, our planet has been home to an estimated 109 billion human beings. And according to another oft-repeated factoid, half of all the people who have ever existed were killed by malaria, the worst mosquito-borne illness. Mosquitoes aren’t merely annoyances, they are mass murderers.

But is this actually true?

There’s little doubt that these hellacious insects are prodigious killers of humankind. The bloodsuckers spread all sorts of diseases – West Nile Virus, various kinds of Encephalitis, Dengue Fever, Yellow Fever, and Zika Virus, for example. However, the damage wrought by all of these diseases is piddling in comparison to malaria. Causing fever, tiredness, vomiting, headaches, and seizures, it struck 216 million people in 2016 alone, resulting in between 445,000 to 731,000 deaths. Believe it or not, that’s an improvement over past years. In 2000, there were 262 million cases, resulting in at least 839,000 deaths.

A new look at 2017 test data reveals an explosion 16 times as powerful than the one that leveled Hiroshima.

Scientists looking anew at a 2017 North Korean nuclear test discovered that the explosion was likely about two-thirds more powerful than U.S. officials previously thought.

Earlier data put the yield somewhere between 30 and 300 kilotons; the U.S. intelligence community said 140 kilotons. That was already the most powerful device tested by North Korea, topping a 2016 test by about an order of magnitude. But a new look at seismological data suggests that the blast was between 148 and 328 kilotons, and probably around 250 kilotons.

Like millions of movie-mad children around the world, Gim Gyu Min dreamed of being a film star when he grew up. But when he huddled in the darkness of the cinema in the 1980s and ’90s, he was forced to watch propaganda praising the North Korean regime.

Now, after a harrowing escape from his country in 1999, he is a filmmaker dedicated to making movies that expose the human-rights abuses there. “I want to let the world know that more and more people are dying under the Kim family dictatorship,” he said.

His movies are based on events that he witnessed during the North Korean famine in the late 1990s, when, among other horrors, he watched a woman being arrested for cannibalism after she resorted to eating her own son. Her child’s head had been found in a cauldron.

Circa 2018

In 1963, L. Herwig proposed the nuclear pumped laser, based on the idea that the ions produced from nuclear reactions can be used as a driver for the laser medium. Since high power and high efficiency lasers with short wavelengths require high pumping power densities, nuclear pumping is an extremely appealing method. Nuclear pumped lasers could therefore direct significant amounts of energy emitted in a nuclear explosion into a very narrowly collimated beam. This beam would not only be able to destroy or damage targets from very long ranges, but also preclude subsequent use due to its own self-damaging mechanism to the initial weapon. [1] This system would ultimately constitute “a ‘third generation’ of nuclear weapons, the first two generations being the atomic (fission) and the hydrogen (fusion) bombs,” according to Edward Teller, also known as “the father of the hydrogen bomb”. [2] In this sense, it would be able to target energy toward specific targets instead of spreading energy into all directions.

Strategic Defense Initiative

On March 23, 1983, President Reagan announced plans to build a defensive Anti Ballistic Missile (ABM) system to protect against a potential intercontinental ballistic missile attack on the United States (Fig. 1). The Strategic Defense Initiative (SDI) program outlines a multilayered defense system. The first line of this defense aimed to destroy missiles in their boost phase just after launch, with a candidate for this first line being the nuclear-explosion-pumped X-ray laser. [2].

Circa 2015

Spaceships in movies and TV shows routinely use tractor beams to tow other vessels or keep them in place. Physicists have been hard at work trying take this technology from science fiction to reality. Significant process has recently been made by a team who have developed a laser tractor beam able to attract and repel particles about 100 times further than has been previously achieved. The lead author of the paper, published in Nature Photonics, is Vladlen Shvedov at Australian National University in Canberra.

Other recent tractor beams have used acoustics or water, but this one uses a single laser beam to control tiny particles about 0.2 millimeters in diameter. The tractor beam was able to manipulate the particles from a distance of 20 centimeters, shattering previous records. Despite this incredible distance, the researchers claim it is still on the short end of what is possible for this tractor beam technique.

“Because lasers retain their beam quality for such long distances, this could work over meters. Our lab just was not big enough to show it,” Shvedov said in a press release.
