Brain-training games promise to enhance our cognitive skills, but their effectiveness remains a controversial topic. What does research tell us about activities that actually benefit our brains? Discover the scientifically proven strategies to boost your mental functions and preserve your cognitive  health.

The cognitive decline associated with aging worries many people, prompting them to look for ways to keep their brains in shape. In response to this concern, the brain-training industry has flourished, offering games that supposedly enhance our mental abilities. But do these apps truly live up to their promises? Cognitive neuroscience researchers have studied the real impact of various activities on brain function, revealing promising approaches for preserving mental agility.

Enhance cognitive skills

The limitations of traditional brain-training games

Brain-training games typically rely on exercises targeting specific cognitive skills, such as attention or working memory. For example, some games ask players to quickly identify letters or numbers according to changing rules. The goal is to train the brain’s executive functions, which are crucial for mental flexibility.

However,  scientific studies struggle to demonstrate the effectiveness of these games beyond the tasks they train. In 2016, the U.S. Federal Trade Commission even fined Lumosity, one of the leaders in the market, $50 million for false advertising. The transfer of skills acquired in these games to real-life situations remains limited.

Nevertheless, some games not specifically designed for brain training show surprising positive effects:

Educational game alternatives

  • Tetris improves mental rotation skills.
  • Real-time strategy games enhance cognitive flexibility.
  • Super Mario 64 increases the volume of the hippocampus, the brain’s memory hub.

Activities that truly benefit the brain

The Synapse Project study compared the impact of various activities on adults’ cognitive functions. The results were revealing: participants who engaged in new and stimulating activities showed significant improvements in memory, processing speed, and reasoning. The chosen tasks, such as digital photography or quilting, had several key characteristics:

Enhance cognitive skills

A significant intellectual challenge.

  1. Learning new skills.
  2. Ongoing engagement (15 hours per week for 14 weeks).

Brain scans revealed an increase in neuronal efficiency in these participants. In contrast, the groups involved in less stimulating activities (crossword puzzles, listening to music) showed no significant improvement.

How to effectively stimulate your brain every day

To leverage these findings, here are a few recommendations for maintaining your mental agility:

StrategyExample Application
Step outside your comfort zoneLearn a new language
Vary the types of challengesAlternate between verbal and numeric activities
Practice regularlyDedicate 30 minutes a day to a stimulating activity
Gradually increase the difficultyMove to a higher level when you feel comfortable

The key is to choose activities that push you out of your comfort zone. If you’re more into literature, try math-based games. On the other hand, if you’re more comfortable with numbers, dive into verbal challenges. This approach engages the frontal and parietal lobes of your brain, enhancing its adaptability.

Brain performance insights

Beyond games, don’t forget the importance of a healthy lifestyle. Quitting smoking, managing your blood pressure, and staying physically active also contribute to preserving your cognitive functions. Combining these habits with mentally stimulating activities offers the best chance to maintain a healthy brain throughout life.

Instead of relying solely on brain-training apps, diversify your sources of cognitive stimulation. Your brain will thank you for these new challenges!

The Deep View: AI fakes emotion, but the consequences are real

RESEARCH
AI fakes emotion, but the consequences are real
Can we teach machines to feel? Short answer: We don’t know. But we can teach them to sound like they do. 
On Thursday, Anthropic published research detailing why AI models sometimes communicate as though they have feelings, finding that models tend to map patterns to emotions, often “organized in a fashion that echoes human psychology.” To put it plainly, these models have learned to mimic human emotions by replicating them in contexts where emotions arise in humans. 
Though Anthropic noted that none of this research points to whether or not these models actually feel anything, the representations of emotion “are functional, in that they influence the model’s behavior in ways that matter.”

Iranian President Masoud Pezeshkian penned an open letter to “the people of the United States” on April 1, 2026, in which he implored Americans to “look beyond” misinformation that portrayed Iran as a threat to the world.

It was, perhaps, his most prominent intervention during the current conflict. Despite being the president of a country in the midst of crisis, Pezeshkian hasn’t had the highest of war profiles.

Criticized by conservatives at home for his conciliatory tone, the reformist politician has also been sidelined by Iran’s adversaries. Western media initially appeared more interested in the musings of Pezeshkian’s son, Yousef. President Donald Trump has barely mentioned Pezeshkian, other than in an oblique social media post on April 1 in which he claimed “Iran’s new regime president” had asked the U.S. for a ceasefire – something denied by Iran.

International attention has instead largely centered on the role of Iran’s supreme leader. First, it was about who would succeed Ali Khamenei after his killing in the first strikes of the war, and then what was known about his successor and son, Mojtaba Khamenei.

As a researcher of contemporary Iranian politics, I think this focus on the supreme leader over the president inadvertently confirms a trend in Iran that has been happening for years: the cementing of a political structure that increasingly resembles a centralized dictatorship.

An uneasy balance

The concentration of power around one figure sits uneasily with one of the founding impulses of the 1979 revolution that ushered in the Islamic Republic. A wide spectrum of revolutionary actors – Islamists, leftists and secular nationalists – were involved in the ousting of the shah. But they shared at least one principle: the rejection of monarchy.

Our mission is to share knowledge and inform decisions.

About us

The idea that one generation could not determine the political future of the next was precisely what many revolutionaries, despite their internal differences, had fought against.

As such, the system that initially emerged in 1979 was neither a pure theocracy nor a conventional republic. The supreme leader would exercise ultimate religious and political authority, and an elected president was to embody the republican dimension of the state. This second part gave institutional form to the revolutionary promise that people, through elections, would periodically renew political authority.

In the first decade after the revolution, this balance functioned, albeit in a fragile and conflictual manner.

The authority of Ruhollah Khomeini, the Islamic Republic’s first supreme leader, coexisted with the presidency – most notably during the brief presidency of Abolhassan Bani Sadr. Elected in 1980, Bani Sadr quickly came into conflict with clerical factions over the direction of the revolution and the conduct of the Iran-Iraq war.

Accused of political incompetence, Bani Sadr was impeached by parliament in 1981 and subsequently fled into exile.

The presidency of his successor, Ali Khamenei, marked a period of relative alignment with the supreme leader. Operating under Khomeini’s authority, Khamenei operated less as an autonomous political force than as an instrument embedded within a broader clerical and revolutionary consensus.

The dynamic between president and supreme leader was further redefined by the 1989 constitutional revision following Khomeini’s death and the elevation of Khamenei from president to supreme leader. The post of prime minister was abolished, consolidating executive authority in the presidency. At the same time, the institutional and political supremacy of the supreme leader was strengthened.

The weakening presidency

The presidency of Mohammad Khatami, who was elected in 1997, demonstrated that the office could still function as a significant locus of power. As Khatami’s tenure showed, presidents were still able to shape public discourse and policy agendas, particularly in areas such as cultural policy, foreign relations and economic management.

But a major turning point in the power of the office occurred in 2009 with the contested reelection of the hard-liner president, Mahmoud Ahmadinejad, amid widespread allegations of electoral fraud.

It led to mass demonstrations that became known as the “Green Movement.” The state responded with the repression of protesters, followed by a consolidation of the security apparatus – particularly the expanding influence of the Islamic Revolutionary Guard Corps around the supreme leader.

At the same time, it marked the beginning of Ahmadinejad’s falling out of favor. His populist rhetoric and attempts to build an independent political base led to confrontations with clerical authorities in the early 2010s. It also exposed the regime’s intolerance for even a relatively autonomous presidency.

It contributed to a power struggle between Ahmadinejad and Supreme Leader Ali Khamenei that became public in 2011 when the then-president sought to dismiss Intelligence Minister Heydar Moslehi – only to be overruled by Khamanei.

Ahmadinejad was subsequently excluded from the 2017 presidential race by the Guardian Council, a body handpicked by the supreme leader. In so doing, Khamenei made it clear that while the office of the presidency could remain, it would cease to function as an independent center of decision-making and power.

Since then, presidents have continued to be elected, but their capacity to reshape the political order has been diminished sharply.

The presidency of Hassan Rouhani briefly appeared to be an exception. His election in 2013, and the subsequent negotiation of the Joint Comprehensive Plan of Action, generated both domestic expectations and significant international attention.

Yet the durability of the agreement remained contingent on decisions taken beyond the presidency, both internationally and domestically. Its eventual unraveling during the first Trump administration confirmed suspicions among Iranian hard-liners around the supreme leader that reform, an independent power center in the presidency and diplomacy with the U.S. had been a mistake.

With even the limited form of democratic expression as embodied through an elected president suppressed, political disengagement has followed. Although voter turnout remained significant in the years immediately following 2009, a longer-term trend has seen people give up faith in elective politics in Iran. In the last election, held in 2024, just 39.9% of Iranians turned out to vote.

Consolidation of power

This diminishing of the role of the presidency and political legitimacy forms the background to any questions of succession now. But by reducing the political future of the country to the identity of future supreme leaders, observers risk normalizing the transformation of what was historically a contested and hybrid political system into one defined by a single office.

The bloody suppression of the January 2026 protests, the constraints imposed by wartime conditions and the increasing marginalization of elective institutions have all contributed to weakening the presidency.

The fallout of the current war may, of course, see a reorganization of political institutions in Iran. But for now, when Pezeshkian seeks diplomacy with Americans, the pertinent question is: Does his office still matter?

Axios: NATO’s Trump-induced coma

NATO’s Trump-induced coma

NATO is a promise, and now it’s broken, write Axios’ Dave Lawler and Zachary Basu.

The alliance was built on the premise that an attack on one member is an attack on all. President Trump has made that conditional: If you won’t help me in my war, I might not show up for yours.

Trump and his team have fumed at NATO allies for denying the U.S. logistical help or access to their airspace or military bases to carry out attacks against Iran. He called them “cowards” for refusing to help reopen the Strait of Hormuz.

Why it matters: NATO’s mutual-defense framework doesn’t apply to the Iran war, far from the alliance’s territory. But these days could be the death knell for the most powerful and consequential alliance of the past eight decades.

Flashback: This all comes months after Trump threatened to seize Greenland, a territory of ally Denmark, and imposed tariffs on any other allies who stood in his way.

That was one of several increasingly existential crises for NATO that have erupted, then died down, over Trump’s two terms.

Friction point: Taken together, Greenland — and now Iran — have forced European leaders to confront the need for a security architecture that could stand without the American pillar.

Even if they stick to their newly robust spending commitments, it’d take several years to be able to “defend and thereby deter Russia,” and perhaps a decade to fully replace the U.S., says Ivo Daalder, a former U.S. ambassador to NATO.

“The big question is: Let’s say there is an actual armed attack on NATO. Would there be a political decision [by Trump] to come to the aid of that ally?” Daalder wonders.

Trump has given ample reason to suspect the answer might be no.

For the allies who share a border with an expansionist Russia, that’s a very worrying prospect.

Zoom in: The Iran war is shaping up as a strategic windfall for Moscow, boosting oil revenues and diverting Western attention.

Russian officials and state media are openly reveling in Trump’s attacks on the alliance, casting them as validation of Europe’s weakness and self-sabotage.

What to watch: While Trump is once again dangling a NATO departure, a 2023 law states that no president can withdraw without Congress. But courts could well side with Trump if he decided to test it, Daalder says.Share this story.

Axios: California Republic … What does this mean? Worth exploring

As goes Sacramento …

To see where tech policy is going in the U.S., look west: California is escalating its push to regulate AI across multiple fronts, Axios’ Ashley Gold reports.

Why it matters: California’s multi-pronged approach makes it likely that AI companies in the U.S. will treat the state’s rules as a de facto national standard, even as the White House moves to rein in state regulation.

It follows a familiar pattern: California acts first, companies adapt to keep doing business there and Congress dithers, eventually yielding to states because of gridlock.

Gov. Gavin Newsom (D) signed an AI executive order this week as state legislators advance a number of AI bills and consider other regulatory avenues for AI.

It aims to “raise the bar for AI companies seeking to do business with the state,” per the announcement, and makes procurement standards stronger.

The state will develop a plan for contracting best practices requiring companies to explain their policies on distribution of illegal content, model bias and violation of civil rights and free speech.

In a clear shot at the Pentagon-Anthropic dispute, the order also enables California to “separate the procurement authorization process from the federal government’s if needed,” the release says.Share this story.

Axios: Get ready for $200 oil

Get ready for $200 oil

Oil prices are popping after President Trump failed to offer a clear plan for reopening the Strait of Hormuz during his Iran speech last night.

Trump called on other countries to “take the lead in protecting the oil that they so desperately depend on.

Officials from more than 40 countries — though not the U.S. — are meeting today to discuss opening Hormuz. 

Oil could surge to an unprecedented $200/barrel if Hormuz stays closed, Axios’ Amy Harder reports.

Brent crude futures are at about $107/barrel as of midafternoon, up 6.7% from yesterday.A line chart that tracks Brent crude oil prices hourly from March 2 to April 2, 2026, in ET. Prices spiked from below $80 to $116 on March 8. Since then, prices have generally been elevating, hitting $107 on April 2.Data: Financial Modeling Prep; Chart: Erin Davis/Axios 

Analysts at Macquarie, a financial services company, say oil could reach $200 if the Iran war drags into June.

Trump said last night that the U.S. campaign will last another two to three weeks. He said after the war, oil will start “flowing and the gas prices will rapidly come back down. Stock prices will rapidly go back up.

Jason Bordoff, founding executive director of Columbia University’s Center on Global Energy Policy, tells Axios: “There is no policy option to prevent oil prices from marching up toward $200 a barrel if the Strait of Hormuz remains closed.” 

$200 oil could be catastrophic for our globalized economy:

Gas and jet fuel prices would skyrocket, prompting painful changes in global energy consumption. Some countries are already rationing fuel or imposing price controls.

Food prices would rocket up as fertilizer gets more expensive.

Prices for foreign-made consumer goods — electronics, clothing, anything else imported — would also climb.Go deeper.

Hegseth fires Army’s top officer, Gen. Randy George

A Defense Department official confirmed a report that George has been asked to step down by Hegseth.

WASHINGTON — Defense Secretary Pete Hegseth has removed the US Army’s 41st Chief of Staff, Gen. Randy George.

The news was first reported by CBS News. A Defense Department official confirmed the report to Breaking Defense, but would not provide further information.

After publication, Pentagon spokesman Sean Parnell said on X that “General Randy A. George will be retiring from his position as the 41st Chief of Staff of the Army effective immediately. The Department of War is grateful for General George’s decades of service to our nation. We wish him well in his retirement.”

It is not immediately clear who will replace George, but it is suspected that Lt. Gen. Christopher LaNeve, who was recently sworn in as the service’s new vice chief of staff, will replace him. LaNeve, a former 82nd Airborne Division commander, replaced Gen. James Mingus, who retired a full two years earlier than expected. (With George’s exit being “effective immediately,” LaNeve will likely slot in as the acting chief until a full confirmation process can be arranged.)

Notably, LaNeve served as a military aide to Hegseth. The secretary posted a congratulatory message after LaNeve was confirmed, calling him a “generational leader” who “will help ensure the Army revives the warrior ethos, rebuilds for the modern battlefield, and deters our enemies around the world.” 

George is exiting the role nearly a year-and-a-half earlier than expected for the traditionally four-year role. He took office in fall of 2023.

Despite his abbreviated time at the helm, George had plenty on his plate: he helped the service navigate through a recruiting crisis, attempted to spiral new technology into the force at a quicker pace under the “Transformation in Contact” initiative, terminated a host of weapon development programs and oversaw a massive overhaul of the service’s acquisition workforce.

And for the past year, George worked closely on the breadth of those changes with Army Secretary Daniel Driscoll, the service’s 26th civilian leader who has been reportedly at odds with Hegseth. As a result of the internal dynamics between Driscoll and Hegseth, there have been rumors that George could be fired for months.

After graduating from West Point, George commissioned as an infantry officer in 1988 before deploying to Desert Shield/Desert Storm with the 101st Airborne Division. Over the next three-and-a-half decades, he also served in Operation Iraqi Freedom, and deployed to Afghanistan as part of Operation Enduring Freedom. His firing comes as the US is once again embroiled in a conflict in the Middle East, this time with Iran. 

Ahead of his ascent to the service’s top military officer post, he also served as the senior military assistant to then-Defense Secretary Lloyd Austin before eventually becoming Army’s vice-chief of staff. 

Latest In A String Of Firings

While Hegseth did not detail why he was asking George to leave, he has promised to purge the Pentagon of “woke” generals supporting diversity and those who carried out orders related to the US withdrawal from Afghanistan. General officers with ties to Austin and former chairman of the Joint Chiefs of Staff Gen. Mark Milley have also been viewed as vulnerable targets, according to sources.

Over the course of the year, the ax fell first on Coast Guard Commandant Adm. Linda Fagan, chairman of the Joint Chiefs of Staff Gen. CQ Brown, Chief of Naval Operations Adm. Lisa Franchetti, Air Force Vice Chief of Staff Gen. James Slife, Defense Intelligence Agency head Lieutenant General Jeffrey Kruse, National Security Agency and Cyber Command head Gen. Timothy Haugh and others. 

The dismissal of top brass became a major political talking point in Washington last year with five former secretaries of defense — Lloyd Austin, William Perry, Chuck Hagel, Leon Panetta and Trump’s first defense secretary, Jim Mattis — issuing an open letter to lawmakers, saying they are “alarmed” by the dismissals. 

“We write to urge the US Congress to hold Mr. Trump to account for these reckless actions and to exercise fully its Constitutional oversight responsibilities,” they wrote, noting that the president has not provided a justification for the firings. 

“Mr. Trump’s dismissals raise troubling questions about the administration’s desire to politicize the military and to remove legal constraints on the President’s power,” the former defense secretaries later added. “We, like many Americans — including many troops — are therefore left to conclude that these leaders are being fired for purely partisan reasons.”

Left unchecked, they warned that potential recruits may shy away from serving in the military and those already in uniform may shy away from “speaking truth to power” for fear of retribution.

UPDATED 4/2/2026 AT 5:10 ET to include information regarding Gen. George’s background and context related to recent firings within the Defense Department.
