The U.S. Military is Buying a Brutal-Looking Powered Exoskeleton

Posted by in categories: cyborgs, military

The partnership could greatly enhance the productivity of a single officer in the field and decrease fatigue or strain — but the USSOCOM didn’t reveal the exact intended use case for the exoskeleton, which lets the wearer heft 200 pounds (90 kg).

Forklift Arms

It’s the latest sign that exoskeletons are finally hitting the mainstream. Automobile manufacturers are already considering the use of simpler exoskeletons on factory floors. And the Food and Drug Administration approved a lower-body exoskeleton last year for use by people with lower limb disabilities.

Project aims to tame noise from supersonic military jets with ‘swirl’ technology

Posted by in categories: engineering, health, military

It’s cliché to describe something very noisy as “louder than a jet engine.” But supersonic jet engines, like those powering fighters flown by the U.S. military, are so much louder than regular jet engines that scientists have a special term for their sound—” broadband shock-associated noise.”

Now, a team of faculty and students from the Department of Aerospace Engineering at the University of Kansas will design and test to cut noise from supersonic military jets. The U.S. Department of Defense’s Strategic Environmental Research and Development Program (SERDP), the DoD’s environmental science and technology program, is supporting a one-year, $200,000 effort at KU, with the potential to expand that support in the years ahead.

Pentagon Wants to Test A Space-Based Weapon in 2023

Posted by in categories: existential risks, military, particle physics, satellites

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.

Deep-Sea Explorers Discover Wreck of WWII Aircraft Carrier USS Wasp

Posted by in category: military

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.

New understanding of sophistication of microbial warfare

Posted by in categories: biotech/medical, chemistry, military

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.

Bizarre Malware Is Disabling Safety Systems at Industrial Plants

Posted by in categories: cybercrime/malcode, military

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.

Doomsday Clock Is Staying at Two Minutes to Midnight This Year

Posted by in categories: climatology, existential risks, military, sustainability

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.”
