Researchers get partial memory control and create "hybrid" memories in mice

By - March 22, 2012 1 Picture
You may remember – pun intended – that earlier in the week we reported on research that may provide an explanation of how memories are stored in the brain. In related news, a team consisting of researchers from the Scripps Research Institute, the University of Oregon and the University of North Carolina has found a way to partially control a specific memory in mice by turning neurons in their brains on and off. Although the research is in its early stages, the scientists say it could lead to a better understanding of how memories form and maybe even provide ways to change people’s thought patterns.

Researchers may have discovered how memories are encoded in the brain

By - March 21, 2012 1 Picture
While it’s generally accepted that memories are stored somewhere, somehow in our brains, the exact process has never been entirely understood. Strengthened synaptic connections between neurons definitely have something to do with it, although the synaptic membranes involved are constantly degrading and being replaced – this seems to be somewhat at odds with the fact that some memories can last for a person’s lifetime. Now, a team of scientists believe that they may have figured out what’s going on. Their findings could have huge implications for the treatment of diseases such as Alzheimer's. Read More

Deonet announces world's smallest USB memory stick

By - December 21, 2011 1 Picture
Just when you think that USB Flash storage can't possibly get any smaller, a company pops up with something so tiny that you're going to need the corded fob to make sure you don't lose it. Dutch promotional product manufacturer Deonet - maker of a diamond-studded Golden USB memory stick and an FSC-certified, maple-enclosed Eco Wood drive - has announced just such a portable storage solution, and is the latest to claim the title of the world's smallest USB stick.

New drug could be the first to prevent the progression of Alzheimer's disease

By - December 18, 2011 1 Picture
Anyone who has watched as Alzheimer’s disease robs a friend or family member of their memories and faculties before ultimately claiming their life knows just what a truly horrible disease it is. According to the World Health Organization, it is the fourth leading cause of death in high-income countries and, due to an aging worldwide population, it is predicted to affect one in 85 people worldwide by 2050 – unless a treatment can be found. Scientists at the Salk Institute for Biological Studies have high hopes for a new drug they have developed that has improved memory and prevented brain damage in mice and is a promising candidate for the first drug capable of halting the progression of Alzheimer’s in humans.

UCLA researchers discover rhythmic secrets of the brain

By - October 9, 2011 2 Pictures
Neuroscientists have long pondered the mechanism behind learning and memory formation in the human brain. On the cellular level, it's generally agreed that we learn when stimuli are repeated frequently enough that our synapses - the gap-connections between neurons - respond and become stronger. Now, a team of UCLA neuro-physicists has discovered that this change in synaptic strength actually has an optimal "rhythm," or frequency, a finding that could one day lead to new strategies for treating learning disabilities.

FeTRAM memory could be faster than SRAM and more energy efficient than flash

By - September 27, 2011 1 Picture
Researchers at Purdue University are developing a new type of computer memory that they claim could be faster than SRAM and use 99 percent less energy than flash memory. Called FeTRAM, for ferroelectric transistor random access memory, the new technology fulfills the three basic functions of computer memory; writing, reading and storing information for a long time. It is also a nonvolatile form of memory, meaning that it retains its data after the computer has been turned off. Its creators claim it has the potential to replace conventional memory systems.

IBM demonstrates multi-bit phase-change memory chip

By - June 30, 2011 1 Picture
Scientists from IBM Research – Zurich are claiming a world-first, for their recent demonstration of “reliable multi-bit phase-change memory [PCM] technology.” PCM involves the use of materials that change between crystalline and amorphous states, the two states having different levels of electrical resistance – data is stored in a binary fashion, using one level to represent a 0, and the other to represent a 1. By applying new techniques to existing PCM technology, the researchers were reportedly able to write and retrieve data 100 times faster than is possible with Flash. Read More

Researchers turn long-term memories on and off with the flip of a switch

By - June 19, 2011 1 Picture
Using electrical probes embedded into the brains of rats, scientists have managed to replicate the brain function associated with long-term behavior and found a way to literally turn memories on and off with the flip of a switch. The scientists hope their research will eventually lead to a neural prosthesis to help people suffering Alzheimer’s disease, the effects of stroke or other brain injury to recover long-term memory capability.

New form of computer memory uses 100 times less power

By - March 14, 2011 3 Pictures
Researchers from the Electrical and Computer Engineering Department of the University of Illinois have developed a new low-power digital memory which uses much less power and is faster than other solutions currently available. The breakthrough could give future consumer devices like smartphones and laptops a much longer battery life, but might also benefit equipment used in telecommunications, science or by the military.

Molecule that can erase or restore long-term memories – in rats

By - March 7, 2011 1 Picture
If you’re struggling to remember the names of classmates from high school, or just can’t forget that time you made a complete ass of yourself in front of your high school crush, then a single molecule known as PKMzeta could be to blame – and increasing or decreasing its activity in the brain could either help you remember those names that seem on the tip of your tongue or drive that embarrassing memory from your head. In a new study, researchers have demonstrated that a memory in rats can either be enhanced or erased long after it is formed by manipulating the activity of the brain enzyme PKMzeta. Read More
