The Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland — in cooperation with the U.S. Missile Defense Agency (MDA) and the U.S. Navy — played a critical role in the successful execution of Flight Test Other-23 (FTX-23). The Feb. 8 test — also known as Stellar Sisyphus — demonstrated sensor tracking and communications link capabilities of the Aegis Weapon System, a cornerstone of naval missile defense for which APL has served as the technical direction agent for many years.

In many parts of America, we take food for granted. With full grocery store shelves and copious options available at the push of a button on food delivery apps, we seldom think about the complex but critical food and agricultural systems behind this abundance.

Fueled by increasing temperatures and droughts, severe wildfires are on the rise around the world — as are the smoke-borne contaminants that harm the environment and human health. In 2023, Canada recorded its worst wildfire season ever, with fires releasing more than 290 million tons of carbon into the atmosphere. California also experienced record-setting fire seasons in 2020 and 2021.

Representatives from the federal government, academia and private industry convened at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, for a tabletop exercise to assess the nation’s preparedness for security threats unique to the bioeconomy. In May 2023, several dozen experts in public health, policy, cyber, physical sciences and law came together to identify vulnerabilities, develop mitigation recommendations and establish a greater understanding of the extent of the threats to key biological capabilities.

Johns Hopkins Applied Physics Laboratory (APL) researchers have developed one of the world’s smallest, most intense and fastest refrigeration devices, the wearable thin-film thermoelectric cooler (TFTEC), and teamed with neuroscientists to help amputees perceive a sense of temperature with their phantom limbs. This advancement, one of the first of its kind, enables a useful new capability for a variety of applications, including improved prostheses, haptics for new modalities in augmented reality (AR) and thermally modulated therapeutics for applications such as pain management.

When the European Space Agency’s Rosetta spacecraft discovered abundant molecular oxygen bursting from comet 67P/Churyumov-Gerasimenko (67P) in 2015, it puzzled scientists. They had never seen a comet emit oxygen, let alone in such abundance. But most alarming were the deeper implications: that researchers had to account for so much oxygen, which meant reconsidering everything they thought they already knew about the chemistry of the early solar system and how it formed. A new analysis, however, led by planetary scientist Adrienn Luspay-Kuti at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, shows Rosetta’s discovery may not be as strange as scientists first imagined.
