New Alzheimer’s treatment slows disease with nanoparticles

Posted by in categories: biotech/medical, nanotechnology, neuroscience

Alzheimer’s is the most common form of dementia, affecting an estimated 6.7 million people in the US. Researchers seeking an effective treatment for the affliction have, over the last 30 years, focused their efforts on a protein known as amyloid beta (A-beta), which form clumps in the brain.

These clumps of A-beta proteins attack nerve cells, resulting initially in short-term memory impairment and later in the loss of judgment, language and thought processes.

Other researchers have previously developed an antibody which can identify and attach itself to A-beta proteins and delay the progression of Alzheimer’s in patients with early-to-mild cognitive impairment by up to 36%.

Mitochondrial DNA fragment losses predict Parkinson’s disease before symptoms appear

Posted by in categories: biotech/medical, neuroscience

The survival of neurons, unlike most other cells in the body, depends largely on the energy provided by mitochondria, intracellular organelles that contain their DNA to function properly.

Depression treatment reverses “backwards” brain signals

Posted by in category: neuroscience

Transcranial magnetic stimulation (TMS) appears to relieve depression by correcting brain signals that are traveling the wrong direction.

Study: There are four types of Alzheimer’s disease

Posted by in categories: biotech/medical, neuroscience

New research suggests that there is no ‘typical’ form of Alzheimer’s disease, as the condition can manifest in at least four different ways.

Physicist says his study supports computer simulation theory

Posted by in categories: biological, computing, neuroscience

Very interesting article.


Now a physicist working at the University of Portsmouth in the UK has published research in the AIP Advances journal that he says provides support to the strange theory.

“I don’t want to paraphrase Morpheus from The Matrix but he said ‘what is real?’” the Associate Professor of Physics, Dr Melvin Vopson, said.

Will Liquid Circuits Make Brain-Imitating Computers?

Posted by in categories: computing, neuroscience

When a positive voltage was applied to the chip, the ions flowed to the pore, where their pressure created a blister between the chip’s surface and the graphite layer. When the blister forced the graphite upward, the device became more conductive, switching its memory state to “on.” Since the graphite stayed lifted even without a current, the chip essentially remembered this state, A negative voltage could pull the chip’s layers back together, resetting the device to its “off” state.

The scientists were able to connect two of these chips to form a logic gate —a circuit that can implement logical operations such as AND, OR, and NOT. They note they can build any other classical logic gate commonly employed in digital computing using their logic gate. This is the first time multiple fluidic memristors have been connected to form a circuit.

Previously, scientists developed fluidic memristors based on tiny syringes or microscopic slits. However, these earlier devices were too bulky and complex to scale up to larger systems. In contrast, the new microchips are compact and scalable, Emmerich says.

Aging: Longer genes may be a main cause, play role in Alzheimer’s

Posted by in categories: biotech/medical, life extension, neuroscience

Scientists say that long genes — which are more susceptible to DNA damage — might be a main cause of the body’s aging and could play a role in. the development of diseases like Alzheimer’s.

Scientists Find Human Brains Are Getting Larger and Larger

Posted by in categories: biotech/medical, health, neuroscience

If someone tells you that you have a big head, take that as a compliment.

Humankind’s brains have apparently gotten bigger and bigger over the years, according to a team of scientists, who are surmising that bigger brains may stave off dementia as folks age.

An international team of researchers, led by the University of California Davis Health, arrived at this finding after studying the MRIs of people starting with those born in the 1930s, all the way through the 1970s.
