Successful Nuclear Fusion Achieved

Scientists working at the Lawrence Livermore National Laboratory have achieved a net gain of energy from a nuclear fusion reaction. This is a watershed moment in fusion research with the potential to upend global energy production, providing a safe, clean, and virtually unlimited source of power. The reaction was achieved in the early hours of December 5th and was formally announced a week later. This is only the first step in a long process that will take years to refine, but it has the potential to solve the looming energy crisis the world faces.
The quest for nuclear fusion is essentially to replicate the process that powers our sun. Within the cores of stars, the extraordinary temperatures and pressure fuse nuclei together, producing energy. Nuclear fusion on Earth is the same principle on a much smaller scale. Using a process called inertial confinement, hundreds of lasers aimed at a small container called a hohlraum produce shockwaves that supercharge a small BB of fuel within, causing the nuclei in the fuel to fuse.
The implications of this discovery are vast, with the potential to provide a clean and reliable energy source for a world desperate to rid itself of fossil fuels. Expectations must be tempered some, as such a future would be decades away and the feasibility of commercial nuclear fusion is still unknown. Additionally, the technology has its applications for nuclear weapons, with the potential that this great discovery is abused as a weapon of war. Nevertheless, this is a bona fide scientific breakthrough, one that offers a glimpse of a brighter future for the entire world.

Organic Glass Found Among Remains of Roman Guard
One of the most dramatic events in the history of the Roman Empire was the eruption of Mount Vesuvius in 79 CE. It is unknown how many perished during the eruption and its fallout, however, haunting images of contorted Pompeiians frozen in time by searing gas and ash paints an image of hellish, alien conditions. In a bizarre twist of the otherworldly occurrence, scientists have found the only documented instance of a victim whose brain was turned to glass by flows from the eruption.

The Mysterious Dodecahedrons From Across Ancient Rome
The ancient Romans left behind architectural marvels, a rich philosophical tradition, and a complete pantheon of gods and heroes, but among their many relics, the Gallo-Roman dodecahedrons remain truly mysterious.
The Crazy Story of How Star Wars Got Made!
On May 14, 1971, George Lucas flew into London for the first time. For a while now, the young director had been workshopping ideas for a space opera, jotting down an increasingly long list of bizarre names for people and places he could build a story around. So when he landed in London, Lucas marched into the office of United Artists head David Picker and convinced the executive to provide the seed money for his next movie.
