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.”

Alberta Electricity Market faces energy-only vs capacity debate as transmission, distribution, and administration fees surge; rural rates rise amid a regulated duopoly of investor-owned utilities, prompting calls for competition, innovation, and lower bills.

Key Points

Alberta's electricity market is an energy-only system with rising delivery charges and limited rural competition.

✅ Energy-only design; capacity market scrapped

✅ Delivery charges outpace energy on monthly bills

✅ Rural duopoly limits competition and raises rates

Last week, Alberta’s new Energy Minister Sonya Savage announced the government, through its new electricity rules, would be scrapping plans to shift Alberta’s electricity to a capacity market and would instead be “restoring certainty in the electricity system.”

The proposed transition from energy only to a capacity market is a contentious subject as a market reshuffle unfolds across the province that many Albertans probably don’t know much about. Our electricity market is not a particularly glamorous subject. It’s complicated and confusing and what matters most to ordinary Albertans is how it affects their monthly bills.

What they may not realize is that the cost of their actual electricity used is often just a small fraction of their bill amid rising electricity prices across the province. The majority on an average electricity bill is actually the cost of delivering that electricity from the generator to your house. Charges for transmission, distribution and franchise and administration fees are quickly pushing many Alberta households to the limit with soaring bills.

According to data from Alberta’s Utilities Consumer Advocate (UCA), and alongside policy changes, in 2004 the average monthly transmission costs for residential regulated-rate customers was below $2. In 2018 that cost was averaging nearly $27 a month. The increase is equally dramatic in distribution rates which have more than doubled across the province and range wildly, averaging from as low as $10 a month in 2004 to over $80 a month for some residential regulated-rate customers in 2018.

Where you live determines who delivers your electricity. In Alberta’s biggest cities and a handful of others the distribution systems are municipally owned and operated. Outside those select municipalities most of Alberta’s electricity is delivered by two private companies which operate as a regulated duopoly. In fact, two investor-owned utilities deliver power to over 95 per cent of rural Alberta and they continue to increase their share by purchasing the few rural electricity co-ops that remained their only competition in the market. The cost of buying out their competition is then passed on to the customers, driving rates even higher.

As the CEO of Alberta’s largest remaining electricity co-op, I know very well that as the price of materials, equipment and skilled labour increase, the cost of operating follows. If it costs more to build and maintain an electricity distribution system there will inevitably be a cost increase passed on to the consumer. The question Albertans should be asking is how much is too much and where is all that money going with these private- investor-owned utilities, as the sector faces profound change under provincial leadership?

The reforms to Alberta’s electricity system brought in by Premier Klein in the late 1900s and early 2000s contributed to a surge in investment in the sector and led to an explosion of competition in both electricity generation and retail. 

More players entered the field which put downward pressure on electricity rates, encouraged innovation and gave consumers a competitive choice, even as a Calgary electricity retailer urged the government to scrap the overhaul. But the legislation and regulations that govern rural electricity distribution in Alberta continue to facilitate and even encourage the concentration of ownership among two players which is certainly not in the interests of rural Albertans.

It is also not in the spirit of the United Conservative Party platform commitment to a “market-based” system. A market-based system suggests more competition. Instead, what we have is something approaching a monopoly for many Albertans. The UCP promised a review of the transition to a capacity market that would determine which market would be best for Alberta, and through proposed electricity market changes has decided that we will remain an energy-only market.
Consumers in rural Alberta need electricity to produce the goods that power our biggest industries. Instead of regulating and approving continued rate increases from private multinational corporations, we need to drive competition and innovation that can push rates down and encourage growth and investment in rural-based industries and communities.

BC Hydro COVID-19 Relief Fund enables small businesses to waive electricity bills for commercial properties during the pandemic, offering credits, rate support, and applications for eligible customers forced to temporarily close.

Key Points

A program that lets eligible small businesses waive up to three months of BC Hydro bills during COVID-19 closures.

✅ Eligible small general service BC Hydro accounts

✅ Up to 3 months of waived electricity charges

✅ Must be temporarily closed due to the pandemic

Businesses are taking advantage of a BC Hydro relief fund that allows electricity bills for commercial properties to be waived during the COVID-19 pandemic.

More than 3,000 applications have already been filed since the program launched on Wednesday, allowing commercial properties forced to shutter during the crisis to waive the expense for up to three months, while Ontario rate reductions are taking effect for businesses under separate measures. 

“To be eligible for the COVID-19 Relief Fund, business customers must be on BC Hydro’s small general service rate and have temporarily closed or ceased operation due to the COVID-19 pandemic,” BC Hydro said in a statement. “BC Hydro estimates that around 40,000 small businesses in the province will be eligible for the program.”

The program builds off a similar initiative BC Hydro launched last week for residential customers who have lost employment or income because of COVID-19, and parallels Ontario's subsidized hydro plan introduced to support ratepayers. So far, 57,000 B.C. residents have applied for the relief fund, which amounts to an estimated $16 million in credits, amid scrutiny over deferred BC Hydro operating costs reported by the auditor general.

Electricity use across B.C. has plummeted since the outbreak began. 

According to BC Hydro, daily consumption has fallen 13% in the first two weeks of April, aligning with electricity demand down 10% reports, compared to the three-year average for the same time period.

Electricity use has fallen 30% for recreation facilities, 29% in the restaurant sector and 27% in hotels, while industry groups such as Canadian Manufacturers & Exporters have supported steps to reduce prices.

BC Hydro Customer Crisis Fund Surplus highlights unused grants, pilot program imbalance, and calls to reduce fees or expand eligibility. Ratepayers, regulators, and social agencies urge awareness, rebates, and aid for overdue electricity bills.

Key Points

A funding carryover from BC Hydro's crisis grants, sparking debate over fee reductions or more aid eligibility.

✅ $2.9M surplus from 25-cent monthly customer fee

✅ Only 2,250 grants issued; awareness and eligibility questioned

✅ Regulator may refund balance or adjust program design

BC Hydro is sitting on a surplus of about $2.9 million in its customer crisis fund, even as BC Hydro rates rise 3% across the province, leading to calls for the utility to reduce its take from the average customer or provide more money to those in need.

B.C. Liberal Energy Critic Greg Kyllo said if the imbalance continues in the year-old pilot program, amid a provincial rate freeze announced by the province, it’s time to cut the monthly 25 cent fee in half.

"If the grant requirement or the need in the province is going to remain where it is, they should look at rolling back the contribution level in the fund," he told CTV News Vancouver from Salmon Arm.

But social agencies who were part of the consultation around the fund in the beginning said it’s more likely that people in need don’t know about the fund and more time is necessary to get the word out.

"If they collect the money, then the program’s got to change to make sure more people are able to be helped," said Gudrun Langolf of the Council of Senior Citizens Organizations of BC.

The customer crisis fund was started in spring 2018 to give people short-term relief when they can’t pay their electricity bills, especially as a $2 monthly hike pressures household budgets. Customers can apply to get a grant of up to $500 to keep the lights on, and up to $600 if electricity heats their homes.

The public utility took in about 25 cents per customer per month which added up to a revenue of $4.5 million in the year since the program started, BC Hydro confirmed to CTV News.

But the agency only gave out 2,250 grants totalling $850,000.

Administration costs added up around $750,000 – leaving the $2.9 million remaining.

The news will come as a welcome relief to those who suddenly struggle to pay their hydro bills, particularly as Alberta ratepayers are on the hook under a utility deferral program elsewhere in Canada.

Some people who come into Disability Alliance B.C. are often anxious and emotional when they’re suddenly unable to pay their bills, said Shar Saremi, an advocate there.

"I’ve had people crying. I’ve had people who have experienced a loss in the family," she said. "A lot of the time people are stressed out, anxious, really upset. They are looking for assistance, and they aren’t sure what is available for them."

She said people are only eligible if their bills are under $1,000, which could be cutting out the people who are most in need. And because the program is in its first year, it could be undersubscribed, she said.

"A lot of people don’t know about the program, don’t know how to apply, or what kind of assistance is out there," Saremi said.

The fund was established thanks to an order from the B.C. Utilities Commission, the utilities regulator in the province.

The pilot program is going to be examined by the regulator at the end of its first year.

"Any remaining balance in the account at the end of the pilot would be returned to residential ratepayers," says a BCUC fact sheet, as BC Hydro rates are set to rise 3.75% over two years. The decision on exactly what to do with the money hasn’t yet been made.

In Manitoba, a similar program is by donation, and in Newfoundland and Labrador a lump-sum credit was offered to bill payers in a separate initiative. That program raised about $200,000 from customers and $60,000 in other income. It spent $199,000 on grants to applicants, but lost about $20,000 a year.

In Ontario, private utilities are expected to raise 0.12 per cent of their revenue, and Hydro One reconnections have highlighted the stakes for nonpayment there. Across the province, those utilities gave out about $7.3 million in grants. Any unused funds in one year are rolled over to the following year.

New York Renewable Energy Contracts secure 23 projects totaling 2.3 GW, spanning offshore wind, solar, and battery storage under CLCPA goals, advancing 70% by 2030, a carbon-free 2040 grid, grid reliability, and green jobs.

Key Points

State agreements securing 23 wind, solar, and storage projects (2.3 GW) to meet CLCPA clean power targets.

✅ 2.3 GW across 23 wind, solar, and storage projects statewide

✅ Supports 70% renewables by 2030; carbon-free grid by 2040

✅ Drives emissions cuts, grid reliability, and green jobs

In a significant milestone for the state’s clean energy ambitions, New York has finalized contracts with 23 renewable energy projects, as part of large-scale energy projects underway in New York, totaling a combined capacity of 2.3 gigawatts (GW). This move is part of the state’s ongoing efforts to accelerate its transition to renewable energy, reduce carbon emissions, and meet the ambitious targets set under the Climate Leadership and Community Protection Act (CLCPA), which aims to achieve a carbon-free electricity grid by 2040.

A Strong Commitment to Renewable Energy

The 23 projects secured under these contracts represent a diverse range of renewable energy sources, including wind, solar, and battery storage. Together, these projects are expected to contribute significantly to New York’s energy grid, generating enough clean electricity to power millions of homes. The deal is a key component of New York’s broader strategy to achieve a 70% renewable energy share in the state’s electricity mix by 2030 and to reduce greenhouse gas emissions by 85% by 2050.

Governor Kathy Hochul celebrated the agreements as a major step forward in the state’s commitment to combating climate change while creating green jobs and economic opportunities. “New York is leading the nation in its clean energy goals, and these projects will help us meet our bold climate targets while delivering reliable and affordable energy to New Yorkers,” Hochul said in a statement.

The Details of the Contracts

The 23 projects span across various regions of the state, with an emphasis on areas that are well-suited for renewable energy development, such as upstate New York, which boasts vast open spaces ideal for large-scale solar and wind installations and the state is investigating sites for offshore wind projects along the coast. The contracts finalized by the state will ensure a steady supply of clean power from these renewable sources, helping to stabilize the grid and reduce reliance on fossil fuels.

A significant portion of the new renewable capacity will come from offshore wind projects, which have become a cornerstone of New York’s renewable energy strategy. Offshore wind has the potential to provide large amounts of electricity, and the state recently greenlighted the country's biggest offshore wind farm to date, taking advantage of the state's proximity to the Atlantic Ocean. Several of the contracts finalized include offshore wind farm projects, which are expected to be operational within the next few years.

In addition to wind energy, solar power continues to be a critical component of the state’s renewable energy strategy. The state has already made substantial investments in solar energy, having achieved solar energy goals ahead of schedule recently, and these new contracts will further expand the state’s solar capacity. The inclusion of battery storage projects is another important element, as energy storage solutions are vital to ensuring that renewable energy can be effectively utilized, even when the sun isn’t shining or the wind isn’t blowing.

Economic and Job Creation Benefits

The finalization of these 23 contracts will not only bring significant environmental benefits but also create thousands of jobs in the renewable energy sector. Construction, maintenance, and operational jobs will be generated throughout the life of the projects, benefiting communities across the state, including areas near Long Island's South Shore wind proposals that stand to gain from new investment. The investment in renewable energy is expected to support New York’s recovery from the economic impacts of the COVID-19 pandemic, contributing to the state’s clean energy economy and providing long-term economic stability.

The state's focus on clean energy also provides opportunities for local businesses, highlighted by the first Clean Energy Community designation in the state, as many of these projects will require services and materials from within New York State. Additionally, Governor Hochul’s administration has made efforts to ensure that disadvantaged communities and workers from underrepresented backgrounds will have access to job training and employment opportunities within the renewable energy sector.

The Path Forward: A Clean Energy Future

New York’s aggressive move toward renewable energy is indicative of the state’s commitment to addressing climate change and leading the nation in clean energy innovation. By locking in contracts for these renewable energy projects, the state is not only securing a cleaner future but also ensuring that the transition is fair and just for all communities, particularly those that have been historically impacted by pollution and environmental degradation.

While the finalized contracts mark a major achievement, the state’s work is far from over. The completion of these 23 projects is just one piece of the puzzle in New York’s broader strategy to decarbonize its energy system. To meet its ambitious targets under the CLCPA, New York will need to continue investing in renewable energy, energy storage, grid modernization, and energy efficiency programs.

As New York moves forward with its clean energy transition, and as BOEM receives wind power lease requests in the Northeast, the state will likely continue to explore new technologies and innovative solutions to meet the growing demand for renewable energy. The success of the 23 finalized contracts serves as a reminder of the state’s leadership in the clean energy space and its ongoing efforts to create a sustainable, low-carbon future for all New Yorkers.

New York’s decision to finalize contracts with 23 renewable energy projects totaling 2.3 gigawatts represents a bold step toward meeting the state’s clean energy and climate goals. These projects, which include a mix of wind, solar, and energy storage, will contribute significantly to reducing the state’s reliance on fossil fuels and lowering greenhouse gas emissions. With the additional benefits of job creation and economic growth, this move positions New York as a leader in the nation’s transition to renewable energy and a sustainable future.

Expanded Hoa Binh Hydropower Plant increases EVN capacity with 480MW turbines, commercial loan financing, grid stability, flood control, and Da River reliability, supported by PECC1 feasibility work and CMSC collaboration on site clearance.

Key Points

A 480MW EVN expansion on the Da River to enhance grid stability, flood control, and seasonal water supply in Vietnam.

✅ 480MW, two turbines, EVN-led financing without guarantees

✅ Improves frequency modulation and national grid stability

✅ Supports flood control and dry-season water supply

The extended Hoa Binh Hydropower Plant, which is expected to break ground in October 2020, is considered the largest power project to be constructed this year, even as Vietnam advances a mega wind project planned for 2025.

Covering an area of 99.2 hectares, the project is invested by Electricity of Vietnam (EVN). Besides, Vietnam Electricity Power Projects Management Board No.1 (EVNPMB1) is the representative of the investor and Power Engineering Consulting JSC 1 (EVNPECC1) is in charge of building the feasibility report for the project. The expanded Hoa Binh Hydro Power Plant has a total investment of VND9.22 trillion ($400.87 million), 30 per cent of which is EVN’s equity and the remaining 70 per cent comes from commercial loans without a government guarantee.

According to the initial plan, EVN will begin the construction of the project in the second quarter of this year and is expected to take the first unit into operation in the third quarter of 2023, a timeline reminiscent of Barakah Unit 1 reaching full power, and the second one in the fourth quarter of the same year.

Chairman of the Committee for Management of State Capital at Enterprises (CMSC) Nguyen Hoang Anh said that in order to start the construction in time, CMSC will co-operate with EVN to work with partners as well as local and foreign banks to mobilise capital, reflecting broader nuclear project milestones across the energy sector.

In addition, EVN will co-operate with Hoa Binh People’s Committee to implement site clearance, remove Ba Cap port and select contractors.

Once completed, the project will contribute to preventing floods in the rainy season and supply water in the dry season. The plant expansion will include two turbines with the total capacity of 480MW, similar in scale to the 525-MW hydropower station China is building on a Yangtze tributary, and electricity output of about 488.3 million kWh per year.

In addition, it will help improve frequency modulation capability and stabilise the frequency of the national electricity system through approaches like pumped storage capacity, and reduce the working intensity of available turbines of the plant, thus prolonging the life of the equipment and saving maintenance and repair costs.

Built in the Da River basin in the northern mountainous province of Hoa Binh, at the time of its conception in 1979, Hoa Binh was the largest hydropower plant in Southeast Asia, while projects such as China’s Lawa hydropower station now dwarf earlier benchmarks.

The construction was supported by the Soviet Union all the way through, designing, supplying equipment, supervising, and helping it go on stream. Construction began in November 1979 and was completed 15 years later in December 1994, when it was officially commissioned, similar to two new BC generating stations recently brought online.
