Flexible, flapping flying machines may be on the horizon
Rigid wings and rotors have made aircraft very successful; nature, however, prefers flexible, flapping flying structures — just look at birds; indeed, the most efficient and acrobatic airfoils in nature are the flexible wings of the bat; Brown University researchers want to adopt the bat’s approach to flying for human use

Can China's future earthquakes be predicted?
To predict earthquakes, China relied on GPS data, which showed movements of two millimeters per year in certain areas of Szechwan province where a May 2008 earthquake killed 70,000 people (20,000 are still missing) and destroyed more than eight million homes; scientists examine a better way to predict disasters

Modern-day piracy poses growing threats, challenges
Forget Captain Kidd, wooden legs, or treasure maps; modern pirates are equipped with supercharged speedboats, large-caliber weaponry, and all the radio intercept technology they need to identify and locate valuable ocean-going booty; on 9/11 we saw what damage a jumbo jet could do when used as a weapon; how about a supertanker as a weapon?

Quantum calibration shows way for super-secure communication
Scientists at Imperial College London have used a new approach to calibrating quantum mechanical measurement directly to calibrate a detector that can sense the presence of multiple individual photons; the ability to sense the presence of individual photons is an important requirement for the development of future long-distance quantum communication devices and networks

UAV-based anti-missile defense appears doomed
DHS’s Project Chloe envisioned a UAV-based system to defend commercial airlines against shoulder-fired missiles; Northrop Grumman tests show the system to be more complex, and costlier, than originally anticipated

Fingerprint "developer" can read a letter from its envelope
U.K. researchers find that disulfur dinitride polymer turned exposed fingerprints brown, as the polymer reaction was initiated from the near-undetectable remaining residues; what is more, traces of inkjet printer ink can also initiate the polymer, allowing detectives to read a letter from the residue it left on the envelope

The long view
AI-Controlled Weapons Should Be Banned from the Battlefield: Experts
AI expert says autonomous systems being used in the current Ukraine conflict need to be prohibited in the same way as chemical and biological weapons. “I’m quite hopeful that we will, at some point, decide that autonomous weapons also be added to the lists of terrible ways to fight war like chemical weapons, like biological weapons. What worries me is that in most cases, we’ve only regulated various technologies for fighting after we’ve seen the horrors of them being misused in battle,” he says.
Using Quantum Computing to Protect AI from Attack
Despite their incredible successes and increasingly widespread deployment, machine learning-based frameworks such as AI remain highly susceptible to adversarial attacks – that is, malicious tampering with their data causing them to fail in surprising ways. AI can thus be fooled into making mistakes, sometimes risking lives — but quantum computing could provide a strong defense.
Training Students to Succeed in the “Fourth Industrial Revolution”
Transformational changes are already underway in the manufacturing industry as technological advancements, such as artificial intelligence (AI) and smart devices from the “fourth industrial revolution” or Industry 4.0., inspire a digital-first approach to engineering. University of Missouri researchers are using a $1 million grant to support the development of an Industry 4.0 lab, training engineering students for the future of digitization in manufacturing.
Tech Breakthrough Could Increase States’ Use of Geothermal Power
Lawmakers in some states have been laying the groundwork to add geothermal power to the electrical grid and pump underground heat into buildings. Now, a technological breakthrough could dramatically expand those ambitions — and perhaps unleash a new wave of policies to tap into geothermal sources. If the technology’s promise is fulfilled, geothermal could power as much as 20% of the U.S. grid.
Using Hydrogen to Power Disaster Relief
A new vehicle will not only get emergency responders safely to the site of an emergency, but also directly provide power at the scene for up to 72 hours as they assess next steps. And it does all this running on hydrogen—a much more sustainable solution for our environment.
Wastewater Can Help Tackle Water Shortages
Europe has experienced severe heat and drought over the last few summers, and 2023 has been no different. Vast swathes of Central and Southern Europe are simply too dry from a lack of rainfall. Water shortages are causing tensions in some countries. But, for now, there’s enough water to go around. Using the precious resource more efficiently is key.
Sediment Movement During Hurricane Harvey Could Negatively Impact Future Flooding
Enormous amounts of sediment, or sand and mud, flowed through Houston waterways during Hurricane Harvey in 2017, due in part to modifications made by humans to bayous, rivers and streams over the past century. Harvey was the largest rainfall event in U.S. history, and it moved 27 million cubic meters of sediment, or 16 Astrodomes, through Houston waterways and reservoirs. This could seriously impact future flooding events and be costly to the City of Houston.
A Review of NIST’s Draft Cybersecurity Framework 2.0
Cybersecurity professionals, and anyone interested in cybersecurity, have noted that the gold standard of cybersecurity is getting a needed polish. “But all that glitters is not gold,” Melanie Teplinsky writes. NIST’s voluntary cybersecurity framework leaves organizations vulnerable to the nation’s most capable cyber adversaries. NIST’s proposed overhaul won’t change that.
