Transcranial electrical stimulation synchronizes brain waves to bolster working memory, aligning neural oscillations across the prefrontal and temporal cortex. This noninvasive brain stimulation may counter cognitive aging by restoring network coupling and improving short-term recall.

Key Points

Transcranial electrical stimulation applies scalp currents to synchronize brain waves, briefly enhancing working memory.

✅ Synchronizes prefrontal-temporal networks to restore coupling

✅ Noninvasive tES/tACS protocols show rapid, reversible gains

✅ Effects lasted under an hour; durability remains to be tested

To read this sentence, you hold the words in your mind for a few seconds until you reach the period. As you do, neurons in your brain fire in coordinated bursts, generating electrical waves that let you hold information for as long as it is needed, much as novel devices can generate electricity from falling snow under specific conditions. But as we age, these brain waves start to get out of sync, causing short-term memory to falter. A new study finds that jolting specific brain areas with a periodic burst of electricity might reverse the deficit—temporarily, at least.

The work makes “a strong case” for the idea that out-of-sync brain waves in specific regions can drive cognitive aging, says Vincent Clark, a neuroscientist at the University of New Mexico in Albuquerque, who was not involved in the research. He adds that the brain stimulation approach in the study may result in a new electrical therapy for age-related deficits in working memory.

Working memory is “the sketchpad of the mind,” allowing us to hold information in our minds over a period of seconds. This short-term memory is critical to accomplishing everyday tasks such as planning and counting, says Robert Reinhart, a neuroscientist at Boston University who led the study. Scientists think that when we use this type of memory, millions of neurons in different brain areas communicate through coupled bursts of activity, a form of electrical conduction that coordinates timing across networks. “Cells that fire together, wire together,” Reinhart says.

But despite its critical role, working memory is a fragile cognitive resource that declines with age, Reinhart says. Previous studies had suggested that reduced working-memory performance in the elderly is linked to uncoupled activity in different brain areas. So Reinhart and his team set out to test whether recoupling brain waves in older adults could boost the brain’s ability to temporarily store information, a systems-level coordination challenge akin to efforts to use AI for energy savings on modern power grids.

To do so, the researchers used jolts of weak electrical current to synchronize waves in the prefrontal and temporal cortex—two brain areas critical for cognition, a targeted approach not unlike how grids use batteries to stabilize power during strain—and applied the current to the scalps of 42 healthy people in their 60s and 70s who showed no signs of decline in mental ability. Before their brains were zapped, participants looked at a series of images: an everyday object, followed briefly by a blank screen, and then either an identical or a modified version of the same object. The goal was to spot whether the two images were different.

Then the participants took the test again, while their brains were stimulated with a current. After about 25 minutes of applying electricity, participants were on average more accurate at identifying changes in the images than they were before the stimulation. Following stimulation, their performance in the test was indistinguishable from that of a group of 42 people in their 20s. And the waves in the prefrontal and temporal cortex, which had previously been out of sync in most of the participants, started to fire in sync, the researchers report today in Nature Neuroscience, a synchronization imperative reminiscent of safeguards that prevent power blackouts on threatened grids. No such effects occurred in a second group of older people who received jolts of current that didn’t synchronize waves in the prefrontal and temporal cortex.

By using bursts of current to knock brain waves out of sync, the researchers also modulated the brain chatter in healthy people in their 20s, making them slower and less accurate at spotting differences in the image test.

“This is a very nice and clear demonstration of how functional connections underlie memory in younger adults and how alterations … can lead to memory reductions in older adults,” says Cheryl Grady, a cognitive neuroscientist at the Rotman Research Institute at Baycrest in Toronto, Canada. It’s also the first time that transcranial stimulation has been shown to restore working memory in older people, says Michael O’Sullivan, a neuroscientist at the University of Queensland in Brisbane, Australia, though electricity in medicine extends far beyond neurostimulation.

But whether brain zapping could turbocharge the cognitive abilities of seniors or help improve the memories of people with diseases like Alzheimer’s is still unclear: In the study, the positive effects on working memory lasted for just under an hour—though Reinhart says that’s as far as they recorded in the experiment. The team didn’t see the improvements decline toward the end, so he suspects that the cognitive boost may last for longer. Still, researchers say much more work has to be done to better understand how the stimulation works.

Clark is optimistic. “No pill yet developed can produce these sorts of effects safely and reliably,” he says. “Helping people is the ultimate goal of all of our research, and it’s encouraging to see that progress is being made.”

Solar Plus Storage is accelerating across utilities and microgrids, pairing rooftop solar with lithium-ion batteries to enhance grid resilience, reduce peak costs, prevent blackouts, and leverage tax credits amid falling prices and decarbonization goals.

Key Points

Solar Plus Storage combines solar generation with batteries to shift load, boost reliability, and cut energy costs.

✅ Cuts peak demand charges and enhances blackout resilience

✅ Falling battery and solar costs drive nationwide utility adoption

✅ Enables microgrids and grid services like frequency regulation

Todd Karin was prepared when California’s largest utility shut off power to millions of people to avoid the risk of wildfires last month. He’s got rooftop solar panels connected to a single Tesla Powerwall in his rural home near Fairfield, California. “We had backup power the whole time,” Karin says. “We ran the fridge and watched movies.”

Californians worried about an insecure energy future are increasingly looking to this kind of solution. Karin, a 31-year-old postdoctoral fellow at Lawrence Berkeley National Laboratory, spent just under $4,000 for his battery by taking advantage of tax credits. He's also saving money by discharging the battery on weekday evenings, when energy is more expensive during peak demand periods. He expects to save around $1,500 over the 10 years the battery is under warranty.

The economics don’t yet work for every household, but the green-power combo of solar panels plus batteries is popping up on a much bigger scale in some unexpected places. Owners of a rice processing plant in Arkansas are building a system to generate 26 megawatts of solar power and store another 40 MW. The plant will cut its power bill by a third, and owners say they will pass the savings to local rice growers. New York’s JFK Airport is installing solar plus storage to reduce its power load by 10 percent, while Pittsburgh International Airport is building a 20-MW solar and natural gas microgrid to keep it independent from the local utility. Officials at both airports are worried about recent power shutdowns due to weather and overload-related blackouts.

And residents of the tiny northern Missouri town of Green City (pop. 608) are getting 2.5 MW of solar plus four hours of battery storage from the state’s public utility next year. The solar power won’t go directly to townspeople, but instead will back up the town’s substation, reducing the risk of a potential shutdown. It’s part of a $68 million project to improve the reliability of remote substations far from electric generating stations.

“It’s a pretty big deal for us,” says Chad Raley, who manages technology and renewables at Ameren, a Missouri utility that is building three rural solar-plus-storage projects to better manage the flow of electricity across the local grid. “It gives us so much flexibility with renewable generation. We can’t control the sun or clouds or wind, but we can have battery storage.”

The first solar-plus-storage installations started about a decade ago on a small scale in sunny states like California, Hawaii, and Arizona. Now they’re spreading across the country, driven by falling prices of both solar panels and lithium-ion batteries the size of a shipping container imported from both China and South Korea, with wind, solar, and batteries making up most of the utility-scale pipeline nationwide. These countries have ramped up production efficiencies and lowered labor costs, leaving many US manufacturers in the dust. In fact, the price of building a comparable solar-plus-storage generating facility is now cheaper than operating a coal-fired power plant, industry officials say. In certain circumstances, the cost is equal to some natural gas plants.

“This is not just a California, New York, Massachusetts thing,” says Kelly Speakes-Backman, CEO of the Energy Storage Association, an industry group in Washington. She says more than 30 states have renewable storage on the grid. Utilities have proposed and states have approved 7 gigawatts to be installed by 2030, and most new storage will be paired with solar across the US.

Speakes-Backman estimates the unit cost of electricity produced from a solar-plus-storage system will drop 10 to 15 percent each year through 2024, supporting record growth in solar and storage investments. “If you have the option of putting out a polluting or non-polluting generating source at the same price, what are you going to pick?” says Speakes-Backman.

She notes that PJM, a large Mid-Atlantic wholesale grid operator, announced it will deploy battery storage to help smooth out fluctuating power from two wind farms it operates. “When the grid fluctuates, storage can react to it quickly and can level out the supply,” she says. In the Midwest, grid-level battery storage is also being used to absorb extra wind power. Batteries hold onto the wind and put it back onto the grid when people need it.

While the solar-plus-storage trend isn’t yet putting a huge dent in our fossil fuel use, according to Paul Denholm, an energy analyst at the National Renewable Energy Laboratory in Golden, Colorado, it is a good beginning and has the side effect of cutting air pollution. By 2021, solar and other renewable energy sources will overtake coal as a source of energy, and the US is moving toward 30% electricity from wind and solar, according to a new report by the Institute for Energy Economics and Financial Analysis, a nonprofit think tank based in Cleveland.

That’s a glimmer of hope in a somewhat dreary week of news on carbon emissions. A new United Nations report released this week finds that the planet is on track to warm by 3.9 degrees Celsius (7 Fahrenheit) by 2100 unless drastic cuts are made by phasing out gas-powered cars, eliminating new coal-fired power plants, and changing how we grow and manage land, and scientists are working to improve solar and wind power to limit climate change as well.

Energy-related greenhouse gas emissions in the US rose 2.7 percent in 2018 after several years of decline. The Trump administration has rolled back climate policies from the Obama years, including withdrawing from the Paris climate accords.

There may be hope from green power initiatives outside the Beltway, though, and from federal proposals like a tenfold increase in US solar that could remake the electricity system. Arizona plans to boost solar-plus-storage from today’s 6 MW to a whopping 850 MW by 2025, more than the entire capacity of large-scale batteries in the US today. And some folks might be cheering the closing of the West’s biggest coal-fired power plant, the 2.25-gigawatt Navajo Generating Station, in Arizona, which had spewed soot and carbon dioxide over the region for 45 years until last week. The closure might help the planet and clear the hazy smog over the Grand Canyon.

OESP Eligibility 2024 updates Ontario electricity affordability: TOU, Tiered, Ultra-Low-Overnight price plans, online bill calculator, higher income thresholds, monthly credits for low-income households, and a winter disconnection ban for residential customers.

Key Points

Raises income thresholds and credits to help low-income Ontarians cut electricity costs and choose suitable price plans.

✅ TOU, Tiered, and ULO price plans with online bill calculator

✅ Income eligibility thresholds raised up to 35% on March 1, 2024

✅ Winter disconnection ban for residences: Nov 15, 2023 to Apr 30, 2024

Residential, small business and farm customers can choose their price plan, either Time-Of-Use (TOU), Tiered or the ultra-low overnight rates price plan available to many customers. The OEB has an online bill calculator to help customers who are considering a switch in price plans and monitoring changes for electricity consumers this year. 

The Government of Ontario announced on Friday, October 19, 2023, that it is raising the income eligibility thresholds that enable Ontarians to qualify for the Ontario Electricity Support Program (OESP) by up to 35 percent. OESP is part of Ontario’s energy affordability framework and other support for electric bills meant to reduce the cost of electricity for low-income households by applying a monthly credit directly on to electricity bills.. The higher income eligibility thresholds will begin on March 1, 2024.

The amount of OESP bill credit is determined by the number of people living in a home and the household’s combined income, and can help offset typical bill increases many customers experience. The current income thresholds cap income eligibility at $28,000 for one-person households and $52,000 for five-person households, and temporary measures like the off-peak price freeze have also influenced bills in recent periods.

The new income eligibility thresholds, which will be in effect beginning March 1, 2024, will allow many more families to access the program as rates are about to change across Ontario.

In addition, under the OEB’s winter disconnection ban, which follows the Nov. 1 rate increase, electricity distributors cannot disconnect residential customers for non-payment from November 15, 2023, to April 30, 2024.

Ontario IESO COVID-19 Control Room Measures detail how essential operators safeguard the electricity grid with split shifts, backup control centres, real-time balancing, deep cleaning, social distancing, and shelter-in-place readiness to maintain reliable power.

Key Points

Measures that protect essential grid operators with split shifts, backup sites, and hygiene to keep power reliable.

✅ Split teams across primary and backup control centres

✅ 12-hour shifts with remote handoffs and deep cleaning

✅ Real-time grid modeling to balance demand and supply

A group of personnel key to keeping Ontario's electricity system functioning may end up locked down in their control centres due to the COVID-19 crisis, according to the head of the province's power operator.

But that has so far proven unnecessary with a change-up in routine, Independent Electricity System Operator CEO Peter Gregg said.

While about 90 per cent of staff were sent to work from home on March 13, another 48 control-room operators deemed essential are still going into work, Gregg said in an interview.

"We identified a smaller cohort of critical operations room staff that need to go in to operate the system out of our control centres," Gregg said. "My biggest concern is to maintain their health, their safety as we rely on them to do this critical work."

Some of the operators manage power demand and supply in real time as Ontario electricity demand shifts, by calling for more or less generation and keeping an eye on the distribution grid, which also allows power to flow to and from Ontario's neighbours. Others do scenario planning and modelling to prepare for changes.

The essential operators have been split into eight teams of six each working 12-hour shifts. The day crew works out of a control centre near Toronto and the night shift out of a backup centre in the city's west end, Gregg said.

"That means that we're not having physical hand-off between control room operators on shift change -- we can do it remotely -- and it also allows us to do deep cleansing," Gregg said. "We're fortunate that the way the room is set up allows us to practice good social distancing."

Should it become necessary, he said, bed, food and other on-site arrangements have been made to allow the operators to stay at their workplaces as a similar agency in New York has done.

"If we do need to shelter these critical employees in place, we've got the ability to do so."

IESO is responsible for ensuring a balance between supply and demand for electricity across the province. Because power cannot be stored, the IESO ensures generators produce enough power to meet peak demand while making sure they don't produce too much.

"You're seeing, obviously, commercial demand drop, some industrial demand drop," Gregg said. "But you're also seeing a shift in the demand curve as well, where normally you have people heading off to work and so residential demand would go down. But obviously with them staying home, you're seeing an increase in residential electricity use across the province."

Some utilities have indicated no cuts to peak rates for self-isolating customers, with Hydro One peak pricing remaining in place for now.

IESO also runs and settles the wholesale electricity markets. Market prices are set based on accepted offers to supply electricity, while programs supporting stable electricity pricing for industrial and commercial users can affect costs against forecast demand.

With the pandemic forcing many businesses to close and people to stay home, and provincial electricity relief for families and small businesses in place, typical power needs fallen about seven per cent at a time of year that would normally see demand soften anyway. It remains to be seen whether, and how much, power needs shift further amid stringent isolation measures and the ongoing economic impact of the outbreak.

Gregg said the operator is constantly modeling different possibilities.

"What we do normally is prepare for all of these sort of emergency scenarios, as reflected in the U.S. grid response coverage, and test and drill for these," he said. "What we're experiencing over the last few weeks is that those drills come in handy because they help us prepare for when the real-time situation actually happens."

Aurelia Boat Club delivers electric boat membership in Seattle, featuring zero-emission propulsion, quiet cruising, sustainable recreation, and a managed fleet with maintenance, insurance, moorage, and charging handled for members seeking hassle-free, eco-friendly boating.

Key Points

Aurelia Boat Club is a Seattle membership offering all-electric boats, with maintenance, insurance, and moorage included.

✅ Unlimited access to an all-electric fleet

✅ Maintenance, insurance, moorage, and charging included

✅ Quiet, zero-emission cruising on Seattle waters

Seattle's maritime scene has welcomed a new player: Aurelia Boat Club. Founded by former Pure Watercraft employees, Aurelia is poised to redefine electric boating in the city, where initiatives like Washington State Ferries hybrid-electric upgrade are underway. The club's inception follows the unexpected closure of Pure Watercraft, a Seattle-based startup that aimed to revolutionize the pleasure boating industry before its financial troubles led to its downfall.

From Pure Watercraft to Aurelia Boat Club

Pure Watercraft, established in 2011, garnered attention for its innovative electric propulsion systems designed to replace traditional gas-powered motors in boats, while efforts to build the first commercial electric speedboats also advanced. The company attracted significant investment, including a notable partnership with General Motors in 2021, which acquired a 25% stake in Pure Watercraft. Despite these efforts, Pure Watercraft faced financial difficulties and entered receivership in 2024, leading to the liquidation of its assets. 

Amidst this transition, Danylo Kurgan and Mrugesh Desai saw an opportunity to continue the vision of electric boating. Kurgan, formerly a financial analyst at Pure Watercraft and involved in the company's boat club operations, teamed up with Desai, a technology executive and startup investor. Together, they acquired key assets from Pure Watercraft's receivership, including electric outboard motors, pontoon boats, inflatable crafts, battery systems, spare parts, and digital infrastructure. 

Aurelia Boat Club's Offerings

Aurelia Boat Club aims to provide a sustainable and accessible alternative to traditional gas-powered boat clubs in Seattle. Members can enjoy unlimited access to a fleet of all-electric boats without the responsibilities of ownership. The club's boats are equipped with electric motors, offering a quiet and environmentally friendly boating experience, similar to how electric ships are clearing the air on the B.C. coast. Additionally, Aurelia handles maintenance, repairs, insurance, and moorage, allowing members to focus solely on enjoying their time on the water. 

The Future of Electric Boating in Seattle

Aurelia Boat Club's launch signifies a growing interest in sustainable boating practices in Seattle. The club's founders are committed to scaling the business and expanding their fleet to meet the increasing demand for eco-friendly recreational activities, as projects like battery-electric high-speed ferries indicate. By leveraging the assets and knowledge gained from Pure Watercraft, Aurelia aims to continue the legacy of innovation in the electric boating industry.

As the boating community becomes more environmentally conscious, initiatives like Aurelia Boat Club play a crucial role in promoting sustainable practices, and examples such as Harbour Air's electric aircraft highlight the momentum. The club's success could serve as a model for other cities, demonstrating that with the right vision and resources, the transition to electric boating is not only feasible but also desirable.

While the closure of Pure Watercraft marked the end of one chapter, it also paved the way for new ventures like Aurelia Boat Club to carry forward the mission of transforming the boating industry, with regional moves like the Kootenay Lake electric-ready ferry and international innovations such as Berlin electric flying ferry showing what's possible. With a strong foundation and a clear vision, Aurelia is set to make significant waves in Seattle's electric boating scene.

Washington-Led Lawsuit Against Energy Emergency challenges President Trump's executive order, citing state rights, environmental reviews, permitting, and federal overreach; coalition argues record energy output undermines emergency claims in Seattle federal court.

Key Points

Multistate suit to void Trump's energy emergency, alleging federal overreach and weakened environmental safeguards.

✅ Challenges executive order's legal basis and scope

✅ Claims expedited permitting skirts environmental reviews

✅ Seeks to halt emergency permits for non-emergencies

In a significant legal move, Washington State Attorney General Nick Brown has spearheaded a coalition of 15 states in filing a lawsuit against President Donald Trump's executive order declaring a national energy emergency. The lawsuit, filed in federal court in Seattle on May 9, 2025, challenges the legality of the emergency declaration, which aims to expedite permitting processes for fossil fuel projects in pursuit of an energy dominance vision by bypassing key environmental reviews.

Background of the Energy Emergency Declaration

President Trump's executive order, issued on January 20, 2025, asserts that the United States faces an inadequate and unreliable energy grid, particularly affecting the Northeast and West Coast regions. The order directs federal agencies, including the Army Corps of Engineers and the Department of the Interior, to utilize "any lawful emergency authorities" to facilitate the development of domestic energy resources, with a focus on oil, gas, and coal projects. This includes expediting reviews under the Clean Water Act, Endangered Species Act, the National Environmental Policy Act, and the National Historic Preservation Act, potentially reducing public input and environmental oversight.

Legal Grounds for the Lawsuit

The coalition of states, led by Washington and California, argues that the emergency declaration is an overreach of presidential authority, echoing disputes over the Affordable Clean Energy rule in federal courts. They contend that U.S. energy production is already at record levels, and the declaration undermines state rights and environmental protections. The lawsuit seeks to have the executive order declared unlawful and to halt the issuance of emergency permits for non-emergency projects. 

Implications for Environmental Protections

Critics of the energy emergency declaration express concern that it could lead to significant environmental degradation. By expediting permitting processes, including geothermal permitting, and reducing public participation, the order may allow projects to proceed without adequate consideration of their impact on water quality, wildlife habitats, and cultural resources. Environmental advocates argue that such actions could set a dangerous precedent, enabling future administrations to bypass essential environmental safeguards under the guise of national emergencies, even as the EPA advances new pollution limits for coal and gas plants to address the climate crisis.

Political and Legal Reactions

The Trump administration defends the executive order, asserting that the president has the authority to declare national emergencies and that the energy emergency is necessary to address perceived deficiencies in the nation's energy infrastructure and potential electricity pricing changes debated by industry groups. However, legal experts suggest that the broad application of emergency powers in this context may face challenges in court. The outcome of the lawsuit could have significant implications for the balance of power between state and federal authorities, as well as the future of environmental regulations in the United States.

The legal challenge led by Washington State Attorney General Nick Brown represents a critical juncture in the ongoing debate over energy policy and environmental protection. As the lawsuit progresses through the courts, it will likely serve as a bellwether for future conflicts between state and federal governments regarding the scope of executive authority and the preservation of environmental standards, amid ongoing efforts to expand uranium and nuclear energy programs nationwide. The outcome may set a precedent for how national emergencies are declared and managed, particularly concerning their impact on state governance and environmental laws.
