How cuddly robots could change dementia care

Companion animals can stave off some of the loneliness, anxiety, and agitation that come with Alzheimer’s disease, according to studies. Sadly, people with Alzheimer’s aren’t always equipped to look after pets, which can require a lot of care and attention.

Enter cuddly robots. The most famous are Golden Pup, a robotic golden retriever toy that cocks its head, barks and wags its tail, and Paro the seal, which can sense touch, light, sound, temperature, and posture. As robots go they’re decidedly low tech, but they can provide comfort and entertainment to people with Alzheimer’s and dementia.

Now researchers are working on much more sophisticated robots for people with cognitive disorders—devices that leverage AI to converse and play games—that could change the future of dementia care. Read the full story.

What tech learned from Daedalus

Today’s climate-change kraken may have been unleashed by human activity, but reversing course and taming nature’s growing fury seems beyond human means, a quest only mythical heroes could fulfill. 

Yet the dream of human-powered flight—of rising over the Mediterranean fueled merely by the strength of mortal limbs—was also the stuff of myths for thousands of years. Until 1988.

That year, in October, MIT Technology Review published the aeronautical engineer John Langford’s account of his mission to retrace the legendary flight of Daedalus, described in an ancient Greek myth. Read about how he got on.

The big story

Psychedelics are having a moment and women could be the ones to benefit

August 2022

Psychedelics are having a moment. After decades of prohibition, they are increasingly being employed as therapeutics. Drugs like ketamine, MDMA, and psilocybin mushrooms are being studied in clinical trials to treat depression, substance abuse, and a range of other maladies.

And as these long-taboo drugs stage a comeback in the scientific community, it’s possible they could be especially promising for women. Read the full story.
