Software Suite Will Bolster Defenses for Soft Targets
Anyone who has ever gone to a major sporting event or concert, taken public transportation, even visited a farmer’s market on a brisk weekend morning, has likely benefitted from soft-target physical security—and perhaps didn’t even know it. DHS S&T is working developing a suite of decision-support software known as Special Event Planning Tools (SEPT) to help those in charge of securing soft targets.

China’s Chip Talent Problem Worsens After Layoffs at U.S. Firm Marvell
Marvell Technology has confirmed that it is eliminating research and development staffs in China – the third U.S. chipmaker that has done so this year as the U.S.-China tech rivalry intensifies. This will hobble China’s chip ambitions and worsen its talent shortfall in the field of designing and manufacturing cutting-edge computer chips.

How China’s Military Plugs into the Global Space Sector
China is using seemingly civilian and academic Chinese research institutions to advance its military goals in space. International organizations like the International GNSS Service need to be aware that even overtly civilian entities can be intertwined with the Chinese military. Collaboration with high-risk Chinese institutions must be done with extreme care to ensure data and products intended to support international science and commerce are not redirected towards unwanted military uses.

U.S. Reliance on Chinese Drones: A Sector for the Next CHIPS Act?
More and more lawmakers from both parties are beginning to pay attention to the issue of drones and national security. Different bills seek to regulate federal agency procurement and use of certain foreign-made unmanned aircraft systems (UASs), or drones. Annie I. Antón and Olivia C. Mauger write that “Building on the bipartisan consensus to enact the 2022 Creating Helpful Incentives to Produce Semiconductors and Science (CHIPS) Act, there is a compelling case that UASs should be a next sector for similar action.”
Helping the U.S. Fast-track Hypersonic Conventional Weapons
Hypersonic weapons have been a top priority for modernizing the armed forces, with ultrafast, long-range and maneuverable munitions being touted as a revolutionary advance in modern warfare. The U.S. has fast-tracked their development and announced plans to field the first conventional hypersonic missile battery this year. Sandia National Lab is helping the U.S. achieve this goal.
Quantum Cryptography Applications
The development of quantum computing means that the use of classic cryptography for secure communications is in danger of becoming obsolete. Quantum cryptography, on the other hand, uses the laws of quantum mechanics to ensure total security. One example of this is quantum key distribution, which enables two parties to secure a message via a random secret key.
Using Quantum Physics to Secure Wireless Devices
From access cards and key fobs to Bluetooth speakers, the security of communication between wireless devices is critical to maintaining privacy and preventing theft. Unfortunately, these tools are not foolproof and information on how to hack, clone and bypass these systems is becoming easier to find.
Enhanced Community Safety by Reimagining Gunshot Detection
A new gunshot detection system delivers new capabilities that significantly improve the response and management of outdoor shootings. The portable system employs two methods of detection for increased accuracy and reduced false positives.
Using AI to Find Rare Minerals
A machine learning model can predict the locations of minerals on Earth—and potentially other planets—by taking advantage of patterns in mineral associations.
