In an intriguing exploration of memory, the University of Cambridge’s Memory Lab is shedding light on the intricate workings of our minds. This initiative, led by Professor Jon Simons, delves into the various facets of memory, offering insights into how we can enhance and preserve our cognitive abilities.
“When anxious thoughts flood our minds, they compete for space in our working memory and impair our ability to recall long-term memories. If we can find ways to reduce stress and anxiety, our memory can often bounce back.”

What exactly is a memory? According to Simons, it’s a complex interplay of brain activities, a skill to hone, and a blueprint for future actions. The Memory Lab invites volunteers to engage in tasks that range from online exercises to MRI scans, all in the quest to decode memory’s mysteries.
If Memory Serves
Memories are biochemical changes that span the brain’s landscape, influenced by factors such as whether a memory is being encoded or reconstructed. The hippocampus plays a crucial role in forming new memories, but long-term storage involves multiple cortical areas.
Short-term memory, with its fleeting nature, is limited to about 7 items, as posited by Harvard’s George Miller. Alan Baddeley, a former director at Cambridge’s MRC Applied Psychology Unit, introduced a ‘working memory’ model that distinguishes between different types of short-term memories.
Long-term memories, on the other hand, allow us to ‘mentally time-travel,’ reliving past events with vivid sensory details. Research suggests that memory reconstruction is a creative process influenced by biases and emotions.
Cambridge’s Long Memory
Cambridge’s memory research legacy includes the work of Sir Frederic Bartlett, whose experiments demonstrated how cultural biases shape our recollections. His famous ‘war of the ghosts’ study revealed how students altered story elements to fit their familiar world.
Another pivotal figure, Brenda Milner, studied patient Henry Molaison, whose case highlighted the hippocampus’s role in memory formation. Her work transformed our understanding of memory.
Peak Performance
Simons, alongside Professor Simon Baron-Cohen, is investigating the UK’s top memorisers to uncover the secrets of their exceptional abilities. Preliminary findings suggest that a psychological trait called ‘systemising’ might be linked to superior memory performance.
For those not naturally inclined to ‘systemise,’ there are strategies to boost memory. Mnemonics, for example, involve spatial thinking, akin to the ‘mind palace’ technique used by ancient orators.
Jon Simons advises making memory triggers distinctive, as this helps the brain differentiate between memories. The hippocampus’s role in pattern separation underscores the importance of creating unique memory cues.
The COVID-19 pandemic’s ‘brain fog’ phenomenon illustrates how routine experiences can blur memories. To enrich our lives, we should seek varied experiences and manage stress, as anxiety can reduce cognitive abilities.
For those eager to delve deeper into memory research, Cambridge offers opportunities to participate in studies.

Los Alamitos Race Course is facing its most serious crisis in years after 18 horses died in 2025, prompting regulators to warn the track that its racing license is at risk without immediate safety reforms. Following three catastrophic injuries in a single day, the California Horse Racing Board has ordered urgent changes—including more veterinarians, stricter medication rules, and enhanced on‑track medical support—as pressure mounts for stronger oversight in a sport already under national scrutiny.
Canadian investors have poured more than US$5.8 billion into U.S. commercial real estate this year, making the U.S. their top destination even amid a lingering tariff dispute. Tight inventory in Canada and greater deal availability south of the border are driving the trend, with data centers and industrial properties emerging as the hottest targets for 2025.
Florida’s insurance commissioner says even industry pros struggle to read today’s 150‑page homeowners policies—leaving residents shocked when hurricane claims are denied. With rising premiums, high replacement costs, and widespread confusion over exclusions like flood and water damage, the state is pushing for simpler, clearer policy language so homeowners know what they’re actually covered for before the next storm hits.
Following the 2025 elections, major metros like New York, Chicago, Miami, Los Angeles, and Boston are implementing policy shifts that could reshape property values, rental income, development timelines, and investment strategy heading into 2026. From New York’s push toward aggressive rent reform to Chicago’s sustainability mandates and Miami’s uncertain mayoral runoff, these changes signal a new era where local politics increasingly dictate market performance. This breakdown highlights the biggest post‑election real estate pivots and what they mean for investors, agents, and finance professionals preparing for a rapidly evolving landscape.
Florida’s Insurance Commissioner is sounding the alarm after thousands of homeowners discovered—only after hurricanes Helene and Milton—that the coverage they thought they had didn’t exist. With nearly 150,000 unpaid claims tied to misunderstood flood exclusions, water‑damage caps, and buried policy clauses, state leaders are pushing to simplify the dense, confusing documents most Floridians never read. As insurance costs remain one of the state’s top concerns, this growing complexity is creating a massive opportunity for real estate, mortgage, and insurance professionals to guide consumers before disaster strikes.
Florida’s insurance market is reliving an old crisis under a new name. Despite reforms meant to stabilize the system, homeowners are being forced out of Citizens and into pricier policies from small insurers with shaky financial histories. Companies tied to past insolvencies are returning with fresh branding, while highly rated carriers continue to deny a majority of claims. With political influence muddying regulation and climate risks rising, experts warn that only a full structural overhaul—not cosmetic reforms—can restore confidence for homeowners, agents, and the entire real estate market.
