After three decades, the Pentagon is betting big on their belief that a dream of the Star Wars initiative may now be closer to a practical concept.

Defense officials have asked for $304 million to fund research into space-based lasers, particle beams, and other new forms of missile defense next year.

Defense officials want to test a neutral particle-beam in orbit in fiscal 2023 as part of a ramped-up effort to explore various types of space-based weaponry. They’ve asked for $304 million in the 2020 budget to develop such beams, more powerful lasers, and other new tech for next-generation missile defense. Such weapons are needed, they say, to counter new missiles from China, Russia, North Korea and Iran. But just figuring out what might work is a difficult technical challenge.

So the Pentagon is undertaking two studies. The first is a $15 million exploration of whether satellites outfitted with lasers might be able to disable enemy missiles coming off the launch pad. Defense officials have said previously that these lasers would need to be in the megawatt class. They expect to finish the study within six months.

More than 70 years after it was torpedoed and sunk during the World War II Battle of Guadalcanal, the aircraft carrier USS Wasp has been discovered in the Coral Sea.

Wasp was spotted on the seabed, in 14,000 feet of water, by the research vessel (RV) Petrel, part of a research organization established by Microsoft Corp. co-founder Paul Allen, in January.

Scientists have known for a century that viruses attack and sometimes kill bacteria, much the way humans come down with the flu. But only recently have they begun to understand the biochemistry that happens as bacteria and virus strive for competitive advantage, with far-reaching implications for medicine and more.

Researchers explain how viruses make a molecular decoy that is used to subvert the CRISPR-Cas bacterial immune system.

What’s most worrisome, one source told MIT Tech, was that the malware crosses a new ethical line.

“Targeting safety systems just seemed to be off limits morally and really hard to do technically,” Joe Slowik, a former information warfare officer in the US Navy who now works at Dragos, an industrial cybersecurity firm that’s been tracking the spread of Triton, told the magazine.

In the realm of memetic warfare:

How a simple “news” tag can change everything.

According to the Bulletin, we’ve done nothing in the past year to make the situation any less precarious — humanity still faces not one, but two “existential threats” in the form of nuclear weapons and climate change.

While the clock remains set at 11:58, the potential of either threat to destroy humanity has increased over the past 12 months, according to the Bulletin’s 2019 statement. We must do something to alter our path.

“Though unchanged from 2018, this setting should be taken not as a sign of stability but as a stark warning to leaders and citizens around the world,” the scientists wrote. “The current international security situation — what we call the ‘new abnormal’ — has extended over two years now… Th e longer world leaders and citizens carelessly inhabit this new and abnormal reality, the more likely the world is to experience catastrophe of historic proportions.”

Nuclear fission — the physical process by which very large atoms like uranium split into pairs of smaller atoms — is what makes nuclear bombs and nuclear power plants possible. But for many years, physicists believed it energetically impossible for atoms as large as uranium (atomic mass = 235 or 238) to be split into two.

That all changed on Feb. 11, 1939, with a letter to the editor of Nature — a premier international scientific journal — that described exactly how such a thing could occur and even named it fission. In that letter, physicist Lise Meitner, with the assistance of her young nephew Otto Frisch, provided a physical explanation of how nuclear fission could happen.

It was a massive leap forward in nuclear physics, but today Lise Meitner remains obscure and largely forgotten. She was excluded from the victory celebration because she was a Jewish woman. Her story is a sad one.
