Scientists solve the mystery of déjà vu - and say NOT experiencing could be a sign your memory is failing

Daily Mail - Science & tech

Scientists claim to have cracked the mystery of déjà vu - and say not experiencing it could be a sign on health issues. Brain scans have revealed the phenomenon is simply the brain checking its memories are correct. They say that not experiencing the strange felling of having experienced something before may actually have issues with their memory. Researchers say the phenomenon is simply the brain checking its memories are correct. Not experiencing it may actually have issues with their memory, the Scottish team say.


Preliminary Evaluation of Long-term Memories for Fulfilling Delayed Intentions

AAAI Conferences

The ability to delay intentions and remember them in the proper context is an important ability for general artificial agents. In this paper, we define the functional requirements of an agent capable of fulfilling delayed intentions with its long-term memories. We show that the long-term memories of different cognitive architec- tures share similar functional properties and that these mechanisms can be used to support delayed intentions. Finally, we do a preliminary evaluation of the different memories for fulfilling delayed intentions and show that there are trade-offs between memory types that warrant further research.


Samsung produces eUFS memory for cars

ZDNet

Samsung Electronics will produce eUFS memory for cars, the company has said. The memory was designed for applications for advanced driver assistance systems (ADAS), dashboard systems, and infotainment usage, the firm said. It has a read speed of up to 850 megabytes (MB) per second and a random reading speed of 45,000 input/output operations per second. It meets the JEDEC UFS 2.1 standard, as well as the upcoming JEDEC UFS 3.0 standard, and has the requisite data refresh and temperature notification features. Temperature notification works via a controller from crossing temperature boundaries, which is important for a touch car environment, Samsung said.


Memory Machine

From a technical standpoint, Apple's ability to group like photos together is impressive. Who could have imagined a phone could ever do such a thing as identify all your pets and group them together under the heading "Fluffy friends"? But it's also something your phone doesn't need to revise history to do, and the music and slideshow-panning effects are heavy-handed attempts on Apple's part to repackage your life back to you: See how much better things look with a smartphone in your hand? All the sophisticated machine learning in the world can't minimize the creepiness of big companies like Facebook and Apple trying to horn in on your personal moments. The more these services try to approximate a warm, human touch, the wider the gap between an actual memory and its simulacrum, a capital-M Memory, starts to seem.


Black Seniors Stroll Down Memory Lane Aiming to Stay Sharp

U.S. News

One particularly striking study suggests highly stressful experiences -- the death of a child, abuse or severe illness, being fired or divorced -- can age the brain before its time. University of Wisconsin-Madison researchers tested cognitive functions that decline with age in still healthy volunteers in their 50s and 60s. Each particularly traumatic event over a lifetime added the equivalent of 1½ years of age-related decline -- even more, four years, for African-Americans, who experienced disproportionately more stressors.
