$7.8M Award Aims to Revolutionize Renewable Energy for Ocean…
A University of Maryland researcher has received a $7.8 million award from the Defense Advanced Research Projects Agency (DARPA) to develop and test a biologically fueled energy source to power research and sensing devices throughout the world’s oceans.
Environmental science and technology Professor Stephanie Lansing is heading up a large, collaborative effort that aims to overcome the need for batteries and ship- or shore-based power cables by using microorganisms in ocean water and specialized bacteria to create a marine-based microbial fuel cell that can produce outputs of up to 10 watts consistently for a year or more.
The devices could power a vast array of ocean sensing devices that provide critical information for understanding marine environments, monitoring climate change and maintaining national security.
“This unique collaboration of interdisciplinary experts will produce a bioinspired system that has game-changing potential to provide direct electric power to improve sensing capabilities while protecting and limiting the impact to the environment through use of this unique bioenergy system,” Lansing said.
The Persistent Oceanographic Device Power (PODPower) system that the team is developing will be suspended in the water, where it can collect and concentrate ocean microbes and bits of organic matter in a special fermentation chamber. Bacteria in the chamber will pre-digest the material, producing a more efficient type of “food” for a second kind of bacteria that colonizes the fuel cell electrodes and releases electrons for direct use.
The design relies on several innovations including a collection net inspired by unique aspects of fish gills, a corkscrew-type auger that feeds the organic matter into the fermentation chamber, and a dual cathode system to drive the microbial fuel cell power to higher levels than previous systems.
In addition to the $7.8 million granted for Phase 1 development and deployment, an additional $3.4 million award is possible to support Phase 2, which will include deployment in multiple settings and generate 100 watts of power.
The first phase of the project will run through Summer 2026 and includes collaborators from eight other institutions and firms: Battelle, the George Washington University, Harvard University, the Institute of Marine and Environmental Technology at the University of Maryland, Baltimore County, James Madison University, Johns Hopkins University, the University of Delaware and Yokogawa Corp. of America.

SUN: Dozens of vehicles moved to planned Maryland ICE facility; advocates concerned
Advocacy groups are raising concerns over a warehouse in Washington County that is slated to become an Immigration and Customs Enforcement processing facility after dozens of black SUVs were moved to the warehouse’s parking lot on Sunday.
“When federal enforcement vehicles begin lining the warehouse lot, it sends a clear message about what’s taking shape in our community,” said the organizer of Hagerstown Rapid Response, Claire Connor. “We refuse to let ICE quietly plant roots in Washington County without transparency, accountability and community consent.”
The 825,620-square-foot warehouse is located at 16220 Wright Road in Williamsport. Access to the facility was blocked by orange traffic barriers and signs outlining regulations and “governing conduct on federal property” with the Department of Homeland Security emblem at the top of the page.
In late January, Washington County issued a news release stating that on Jan. 14, the U.S. Department of Homeland Security sent a letter to the county’s historic district commission and department of planning and zoning regarding the property.

Howard County police investigate fatal officer-involved shooting in Columbia
COLUMBIA, Md. (WBFF) — An adult man was killed in a police-involved shooting in Columbia early Sunday, prompting an investigation by the Maryland Attorney General’s Independent Investigations Division.
Howard County police said officers were called on March 1, at about 12:09 a.m., to an apartment building in the 6400 block of Freetown Road for a report that involved an adult male threatening to harm himself.
According to police, at about 12:22 a.m., officers encountered the man outside the building. The man approached officers while holding a knife and ignored commands to drop the weapon, police said. Officers then shot the man.

Officers attempted life-saving measures, but the man was pronounced dead at the scene. Officersrecovered a knife near the man.
No officers were injured, and the officers were equipped with body-worn cameras.
The Independent Investigations Division is investigating.
Anyone with information about this incident, including cell phone or private surveillance video, is asked to contact the IID at (410) 576–7070 or by email atIID@oag.maryland.gov.
The IID willgenerally releasethe name of the decedent and any involved officers within two business days of the incident, although that period may be extended, if necessary,pursuant toIID protocol.

TheIID willgenerally releasebody-worn camera footage within 20 business days of an incident. There may be situations where more than 20 days is necessary, including if investigators need more time to complete witness interviews, if there are technical delays caused by the need to shield the identities of civilian witnesses, or to allow family members to view the video before it is released to the public.
