Are We Forgetting How to Remember?
Our culture once depended on the memorization and recitation of long-form narratives like stories and poems. What does it mean that we are losing our capacity to recall our own culture?
Journalist Joshua Foer documents the decline and fall of the modern memory thanks to digital devices that store everything from phone numbers to mathematical formulae. "We remember facts about subjects we are interested in—football or gossip—but day-to-day memories are often devoid of meaning: dates, numbers, definitions or names. These we tend to be poor at recalling. The trick, therefore, is to transform these grey bits of data into something colourful through the use of some energetic imagination. In this way, all sorts of feats become possible."
It's a development that could one day lead to much better treatments for osteoporosis, joint damage, and bone fractures.
- Scientists have isolated skeletal stem cells in adult and fetal bones for the first time.
- These cells could one day help treat damaged bone and cartilage.
- The team was able to grow skeletal stem cells from cells found within liposuctioned fat.
Gut bacteria play an important role in how you feel and think and how well your body fights off disease. New research shows that exercise can give your gut bacteria a boost.
- Two studies from the University of Illinois show that gut bacteria can be changed by exercise alone.
- Our understanding of how gut bacteria impacts our overall health is an emerging field, and this research sheds light on the many different ways exercise affects your body.
- Exercising to improve your gut bacteria will prevent diseases and encourage brain health.
A groundbreaking new study shows that octopuses seemed to exhibit uncharacteristically social behavior when given MDMA, the psychedelic drug commonly known as ecstasy.
- Octopuses, like humans, have genes that seem to code for serotonin transporters.
- Scientists gave MDMA to octopuses to see whether those genes translated into a binding site for serotonin, which regulates emotions and behavior in humans
- Octopuses, which are typically asocial creatures, seem to get friendlier while on MDMA, suggesting humans have more in common with the strange invertebrates than previously thought
