1Heavy sweetener use linked to faster memory decline
The problem. Many people use low-calorie sweeteners instead of sugar. Researchers are still asking whether these sweeteners affect memory and thinking over many years.
What they found. Researchers in Brazil followed nearly 13,000 adults. Their average age at the start was 52. The team tracked them for about 8 years. In people who used the most sweeteners, memory and thinking scores fell 62% faster than in those who used the least.
Try this. Read the ingredient list on one drink or snack you often buy, and notice what is in it.
How sure is this? This study watched people over time. It shows a link, not proof, and diet was reported once from memory. No link appeared in people over 60.
2Pure cranberry juice slowed plaque regrowth in a small test
The problem. Dental plaque is the sticky film on teeth that makes acid and can lead to cavities. Many people want simple ways to keep their mouths healthier.
What they found. In a small trial, 22 people (14 children and eight adults) were randomly given one of three drinks. These were pure cranberry juice, a sugary cranberry drink or water. Swishing the pure juice slowed plaque regrowth and cut the acid plaque makes over 30 minutes.
Try this. Next time a food or drink claims a health benefit, look for how many people were tested and for how long.
How sure is this? This was a small trial with 22 people, tested for only 30 minutes. It cannot show whether drinking juice regularly prevents cavities.
3A therapist says feeling disconnected can happen in four ways
The problem. Feeling numb, spaced out or cut off from yourself can be confusing and even scary. People often use one word for very different experiences.
What they found. A trauma therapist argues that what is often called dissociation (feeling detached from yourself or your surroundings) works in four different ways. She says knowing which one is at work can guide what helps. She notes that many such moments are temporary and harmless.
“I like describing this type as if the volume of the experience has been turned down.”
Antonieta Contreras, author of Traumatization and Its Aftermath
Try this. Notice one moment today when you feel distracted or far away, and describe it in a few plain words.
How sure is this? This is one therapist's opinion piece based on her clinical work, not a new study. Researchers disagree about where some of the four types belong.
4A psychologist says 5 minutes of savouring can help joy last
The problem. Good moments often pass quickly, while worries stick. Many people feel happiness fade fast and wonder why.
What they found. Psychologist Deborah Serani argues that the brain is built to spot danger first and to get used to good things. She suggests savouring (slowly enjoying) a pleasant moment for 5 full minutes. She also suggests finding one good thing about your day before sleep.
Try this. Pick one pleasant moment today, such as a warm drink, and give it 5 unhurried minutes.
How sure is this? This is one psychologist's opinion piece with no new study. She notes that savouring can feel hard at first, especially with depression.
5Namibian Lion Rangers help farmers and desert lions share land
The problem. When lions move into land where people farm, both sides can lose. Farmers worry about their animals, and lions can be killed in return.
What they found. In north-west Namibia, community Lion Rangers work across 11 conservancies (community-run areas). They use smartphones, camera traps, GPS collars and tracking skills passed down to them to warn farmers. Illegal lion killings have ended in six of these areas. The desert lion population now stands at 60, which the rangers consider stable.
“You can't do conservation without including the community.”
Mathilde Brassine, Lion Rangers coordinator
Try this. Think of one neighbour or local group that knows your area well, and send them a short thank-you.
How sure is this? This is a news story about one programme, not a study. Conflict has risen again, mostly because changing weather moves the lions' wild prey.
