US warship sailor confirms seeing mysterious flying ships emerging from ocean
US Navy’s Senior Chief Operations Specialist Alexandro Wiggins has come forward to share his firsthand UAP sighting.
In February 2023, during routine operations off the coast of Southern California, the crew of the US Navy’s Independence-class littoral combat ship USS Jackson recorded a sequence of unidentified aerial phenomena (UAP) exhibiting anomalous behavior.
The incident involved four aerial objects that appeared to rise from the ocean without any visible means of propulsion. This event is similar to the well-known 2004 “Tic Tac” encounter.
Senior Chief Operations Specialist Alexandro Wiggins, a 23-year veteran of the US Navy and a radar expert, has come forward to share his firsthand account.
UAP breaching the ocean surface
Wiggins, whose responsibilities aboard the USS Jackson included tactical airspace monitoring and identification, detected irregular radar returns while stationed in the ship’s Combat Information Center (CIC).
To visually confirm the irregularities, he moved the topside of the ship.
He observed what appeared to be a luminous object surfacing from the sea and ascending, behavior inconsistent with any known aerial platform.
Upon returning to the CIC, Wiggins utilized the ship’s SAFIRE system, a thermal imaging sensor designed for maritime surveillance, to acquire and track the target.
What initially appeared to be a single contact rapidly became a four-object formation, each resembling the cylindrical, tic-tac-like profile previously reported in US Navy engagements.
Wiggins reportedly said the objects displayed no exhaust signature or thermal trail, a critical indicator of conventional propulsion systems.
Moments later, all four objects accelerated simultaneously toward the northeast at a velocity and synchronization that he described as “two steps behind instantaneous.”
Wiggins clarified that the USS Jackson did not file a formal incident report.
The reason for not filing an incident report is that the objects stayed at a safe distance and showed no clear signs of aggression.
According to current Navy rules, these conditions do not require automatic threat reporting.
His account nonetheless contributes to a growing body of military-observed UAP incidents in the Southern California Operating Area (SCOA), which has been the locus of anomalous aerial activity in recent years.
Not the first incident
This is not Wiggins’s first encounter in high-interest maritime airspace.
He previously served aboard the USS Omaha, one of ten Navy warships that reported being swarmed by unidentified aerial contacts in 2019.
That series of incidents produced radar and thermal imaging evidence of multiple large, spherical objects maneuvering around the vessel for over an hour, one of which was observed submerging into the sea.
While Wiggins said he is not a whistleblower, he believes the continued public minimization of UAP incidents undermines operational transparency.
“I’m not trying to make waves,” he said. “I served with pride. But this happened, and it’s operationally significant.”
Symmetric cells utilizing the LixAg alloy exhibited exceptional stability for approximately 1,200 hours at a current density of 0.2 mA/cm². This performance surpassed that of conventional lithium metal anodes.
Furthermore, the interfacial resistance between the LLZTO electrolyte and the LixAg anode was measured at an ultralow 2.5 Ω·cm², which indicates highly efficient ion transport across the interface.
“This dramatic reduction in interfacial resistance enables both higher power output and improved energy efficiency,” added the press release.
‘Soft lattice’ for sustained diffusion
The researchers attribute the LixAg alloy’s success to its unique physical properties, including a low eutectic point and high mutual solubility with lithium.
The research team suggests their findings offer a valuable guide for selecting other alloy phases for anode materials in garnet-based solid-state batteries.
“Alloys with low eutectic temperatures and high mutual solubility with lithium should be prioritized in future research efforts,” concluded the team.
“By solving the interface stability issue while enhancing lithium diffusion kinetics, the LixAg alloy anode brings us one step closer to a future where solid-state batteries power everything from smartphones to electric vehicles with unprecedented energy density and safety.”
Buried for 50 years: US legacy nuclear waste remains shifted to new graveyard
With near completion, teams at the processing center have successfully handled Oak Ridge’s inventory of transuranic debris waste.
A highly radioactive waste, stored for over five decades at Oak Ridge National Laboratory (ORNL), has been successfully processed and shipped for permanent disposal.
Officials recently confirmed the successful removal and shipment of a highly radioactive radium-226 source, which marks a critical victory in the site’s long-term environmental cleanup mission.
This latest shipment represents tangible progress. Teams at the processing center have now successfully processed nearly all (98%) of Oak Ridge’s inventory of transuranic debris waste.
However, handling the potent radium-226 source demanded extreme caution and specialized techniques at the Transuranic Waste Processing Centre.
Employing a multi-layered strategy
Workers navigated rigorous protocols and employed a multi-layered containment strategy.
“They placed the source in a vessel, which they inserted into a 55-gallon drum. Crews then placed that drum inside a larger drum,” explained ORNL.
This entire assembly was then loaded into a heavily shielded transportation cask, which was specifically engineered to prevent radiation release and withstand severe transit accidents.
“Packaging a radioactive source like this one requires considerable expertise and a knowledge of the packaging protocols required to provide protection from radiation during transit and ultimate disposal,” noted Patrick Rapp, the Centre’s area project manager.
Canada has also launched a similar project. The country’s Nuclear Waste Management Organization (NWMO) has chosen a site for its first deep geological repository for used nuclear fuel.
Earlier, Finland became the first country in the world to attempt the burial of nuclear fuel waste in a geological tomb, where it is planned to be stored for the next 100,000 years.
By examining internal resistance and relaxation voltage during pulse charging, the system detects early signs of lithium plating—well before it becomes a threat. This innovation could significantly reduce battery degradation and safety risks, and it can be easily deployed through software updates or cloud-based platforms, making it highly practical for EV manufacturers and battery management system developers.
Under lithium plating conditions, the thickness of lithium-ion batteries increased more than during standard charging, peaking during the constant voltage phase. After this point, the thickness decreased due to the reversible nature of lithium.

China’s solid-state EV battery breakthrough shows stable performance over 1,200 hours
The alloy’s effectiveness stems from its low eutectic point and high lithium solubility.
Researchers at China’s Huazhong University of Science and Technology have announced a solution to a long-standing challenge hindering the commercialization of all-solid-state lithium metal batteries.
The team has created a novel mixed ion-electron conducting (MIEC) LixAg alloy anode that stabilizes the critical interface between lithium metal and garnet-type solid electrolytes, which could lead to safer, higher-energy-density batteries.
“The technology could enable the next generation of electric vehicles with longer ranges, faster charging capabilities, and enhanced safety profiles,” said the researchers in a press release.
Addressing the instability issue
The unstable interface between lithium metal anodes and solid electrolytes, particularly materials like Li6.5La3Zr1.5Ta0.6O12 (LLZTO), has been a major bottleneck for years.
This instability leads to poor lithium diffusion and the formation of lithium dendrites, which can cause short circuits and limit battery life.
“What makes this approach revolutionary is how it fundamentally changes lithium ion movement at the critical interface,” explain the researchers.
“The LixAg alloy creates a pathway for lithium ions that dramatically enhances diffusion kinetics, preventing the concentration gradients that typically lead to dendrite formation and interface degradation.”

New EV battery tech detects dangerous lithium buildup with 97% accuracy, no teardown
This solution can help avoid the lithium plating phenomenon.
Electric vehicles (EVs) are seen as a solution in a bid to achieve a greener future. However, the ability to scale their usage faces a critical hurdle – lithium plating in lithium-ion batteries. This phenomenon occurs during fast charging, at low temperatures, or at high states of charge, leading to catastrophic accidents at times.
Researchers from the University of Shanghai for Science and Technology have developed a novel solution to combat this issue. They have introduced a new lithium-ion plating detection system that analyzes data collected during pulse charging to identify the subtle electrical signals that indicate plating is occurring.
How does this system work?
The system identifies early signs of lithium plating by analyzing resistance and voltage patterns during pulse charging. This early warning can prevent battery degradation and safety risks. It can be deployed via software updates or cloud-based platforms, making it ideal for EV makers and battery management systems.
A major breakthrough in this research is a feature extraction technique that converts limited battery data into rich, multi-dimensional features. While single-feature analysis yielded only 68.5% detection accuracy, the multi-dimensional approach achieved over 97%.
