TODAY



Firefighter Genevieve Hansen tearfully testified at the Derek Chauvin trial
about how officers refused to let her administer medical attention to George
Floyd. The defense’s response? The stress of the situation may have altered
Hansen’s memory. That exchange reminds us of the mysterious science behind what
we recall. Today's Daily Dose takes a deep dive into the vagaries of memory,
innovative ways to improve it, some unforgettable superstars and the future of
grasping the past.

MEMORY SUPERSTARS

These People Never Forget a Face

He’s a criminal’s worst nightmare. British policeman Andy Pope never forgets a
face; in fact, he identified 1,000 criminal suspects from watching CCTV footage
and riding mass transit from 2012 to 2017. He’s extraordinary but not alone. He
belongs to a category of people called super recognizers, some of whom are even
beating out facial recognition software tools. Think you might be one? They only
make up about 1 to 2 percent of the population, but you can test your prowess by
taking online assessments such as this one offered by Harvard University and
Dartmouth College.

The Long Term Memory Game

Do you know what you did last summer? What about 41 years ago on Aug. 29? Jill
Price, 55, remembers: It was a Friday, and the then-teenager went to Palm
Springs with her twin friends, who got bikini waxes. Mind you, this answer came
instantly, without a moment’s thought or preparation. She was the first person
diagnosed with a condition scientists call highly superior autobiographical
memory, and she was just one of about 60 such individuals as of 2017. Scientists
hope studying these “never forgetters” could reveal new lessons about memory
loss and retention.

A Little Shock Doesn’t Hurt

If you don’t have superhuman memory, never fear — technology is here! A Boston
University study found that electrical stimulation of the brain improves memory.
Which led an Australian startup, Humm, to conclude it should spend millions to
create a wearable patch that shocks its wearer. The startling concept, premised
on mild electrical stimulation, helped Humm raise $2.6 million in 2019 to test
out the product. Soon we could all be one jolt away from becoming memory
geniuses ourselves!

View From Above

Artist Stephen Wiltshire is famous for his panoramic skyline views, which he
draws entirely from memory. The autistic savant has a gallery in London and has
traveled the world while creating his unforgettable images. He got started at
age 8 when he sold his first work — a sketch of Salisbury Cathedral commissioned
by former U.K. Prime Minister Edward Heath. Since then, Wiltshire has sold out a
number of exhibitions, and his story has been featured in multiple books and
documentaries marveling at his memorable artistic feats.




IMPROVE YOUR MEMORY

Cut the Sugar!

New research from the University of Georgia and a Southern California research
group reveals sugar consumption in adolescence can impair memory. While they
haven’t tested the theory on humans, the scientists found that young rats that
consumed sugar-sweetened beverages daily had impaired performance on memory
tasks as adults. So while sugars are increasingly being used to help treat
things like cancer, you may want to think twice before overindulging.

Back to the Drawing Board

Many educators ban digital devices in the classroom, and it turns out they have
solid scientific ground to do so. Researchers at the University of Tokyo found
that writing on a physical piece of paper was better for retaining information
than typing notes on your tablet or smartphone. Maybe it’s time to add a pencil
sharpener to your work-from-home setup.

A Walk to Remember

If pandemic isolation prompted you to take more neighborhood walks, you may be
giving your brain a workout too. A recent study showed that going on a brisk
walk or getting regular exercise helped middle-aged adults and seniors with
early signs of memory loss improve their cognitive abilities. Researchers
hypothesized the reason may be the increased blood flow to the brain. Take a
hike? Don’t mind if we do.

WHEN MEMORY FAILS

Time Warp

Time lost all meaning during the COVID-19 lockdowns. For some, that translates
to relationships that accelerate way too fast, an experience affectionately
dubbed “apocalypsing.” For others, it may be the feeling that days drag on while
suddenly months of quarantine have elapsed. Recollections formed during
emotionally charged, stressful or significant times are called “flashbulb
memories.” They often last longer than more typical memories and are more
vulnerable to manipulation. The creation of false memories in high-stress
situations concerns pandemic researchers, who wonder how we will look back on
the events of the past year — and whether we can trust those memories. And what
does it say about memory that most of ours are so heavily tethered to pop
culture events, from TikTok to Tiger King?

Broken Brain

If you feel like you broke your brain, you aren’t alone. When your brain is
under duress, multitasking is near impossible. Managing too much makes your
memory decline because you are overloading the brain’s executive functioning
capacity, experts say. The broken brain feeling is worse for parents. So don’t
worry if you can’t remember where your kid left their shoes, or if you’re
forever mixing up your children’s names. Blame your overwhelmed brain!

False Memories, or Lies?

“Then [David] Letterman asked the question that would destroy Brian Williams’
career.” That’s the tantalizing tease Malcolm Gladwell drops in his Revisionist
History podcast episode on memory … and how it failed the NBC News anchor in the
worst possible way. Williams went on to tell a war story about being on a
helicopter that was hit by gunfire — only, it wasn’t true. But, Gladwell asks,
does that make him a liar? Society insists that lapses of memory equate to
lapses of character. But the reality may be far murkier.

Lost in Brain Fog

Even after people get vaccinated, one of the lingering effects of COVID-19 will
be its impact on survivors’ brains. Some COVID long-haulers describe suffering
from “brain fog,” in which they experience short-term memory loss, confusion and
difficulty focusing. It’s the fourth most common symptom of the virus, and
experts are unsure how long it will take for people to recover … or if they will
at all.

The Brain Craves…

When we are stressed, we crave comfort foods. Our spatial brain is partially at
fault — blame it on our hunter-gatherer ancestors. Spatial memory developed to
prioritize remembering the location of high-calorie foods, making them a lot
harder to avoid in kitchen pantries now. From the French massively increasing
their cheese intake during the pandemic to the chips calling to you from the
cupboard, COVID has tested our willpower … and our belt buckles.

MEMORY’S FUTURE

If He Only Had Synthetic DNA

The scarecrow can forget all about needing a brain. University of Texas
researchers have uploaded The Wonderful Wizard of OZ to synthetic DNA, unveiling
a process that allows you to store large amounts of data on strands of genetic
material. Reporters from the Verge followed suit, encoding their memories from
the crazy year that was 2020. Screw “the cloud.” Pretty soon, we’ll be storing
our bank passwords in our cells instead.

Hippocampus Autopilot

Do you ever feel like you’re on autopilot, even when entering a new situation?
MIT scientists have discovered specialized cells that create “event code” living
in the hippocampus, the part of the brain responsible for learning and memory.
They are activated by new situations in similar settings, such as going to a new
restaurant. While you’ve never seen the menu, your event codes kick in, so you
know to look for, say, an appetizer list or a favorite entree. Scientists hope
to harness such “transfer learning” to prepare people to learn new things from
fresh scenarios by drawing on past experience.

Cutting Out Alzheimer’s

What if you could control-alt-delete the Alzheimer’s gene? While we’re far from
deploying it on humans, scientists in South Korea managed to treat mice with
Alzheimer’s by using the CRISPR gene-editing tool to edit out the BACE1 gene
associated with the disease. Such splicing technology will have ramifications
across scientific fields, from creating “designer babies” to crunchy CRISPR
groceries. But for now, we’d settle for more easily remembering where we left
our keys.

Reversing False Memories

Elizabeth Loftus is a cognitive psychologist specializing in the fickle nature
of memory. Her testimonies in several high-profile sexual misconduct cases,
including the Harvey Weinstein trial, have been used to discredit recollections
of accusers and survivors. Those arguments have helped shape the legality of
using memories as fact in legal cases, which could benefit both defendants and
accusers. Either way, recent research discovered that false memories can be
corrected without harming the true memory’s integrity. That means the arguments
by Chauvin’s lawyer in the George Floyd trial — refuting the memories of
firefighter Genevieve Hansen — may not be as airtight as the defense team would
like to believe.
