A new theory for how memories are stored in the brain
2021-03-01
(Press-News.org) Research from the University of Kent has led to the development of the MeshCODE theory, a revolutionary new theory for understanding brain and memory function. This discovery may be the beginning of a new understanding of brain function and in treating brain diseases such as Alzheimer's.
In a paper published by Frontiers in Molecular Neuroscience, Dr Ben Goult from Kent's School of Biosciences describes how his new theory views the brain as an organic supercomputer running a complex binary code with neuronal cells working as a mechanical computer. He explains how a vast network of information-storing memory molecules operating as switches is built into each and every synapse of the brain, representing a complex binary code. This identifies a physical location for data storage in the brain and suggests memories are written in the shape of molecules in the synaptic scaffolds.
The theory is based on the discovery of protein molecules, known as talin, containing "switch-like" domains that change shape in response to pressures in mechanical force by the cell. These switches have two stable states, 0 and 1, and this pattern of binary information stored in each molecule is dependent on previous input, similar to the Save History function in a computer. The information stored in this binary format can be updated by small changes in force generated by the cell's cytoskeleton.
In the brain, electrochemical signalling between trillions of neurones occurs between synapses, each of which contains a scaffold of the talin molecules. Once assumed to be structural, this research suggests that the meshwork of talin proteins actually represent an array of binary switches with the potential to store information and encode memory.
This mechanical coding would run continuously in every neuron and extend into all cells, ultimately amounting to a machine code coordinating the entire organism. From birth, the life experiences and environmental conditions of an animal could be written into this code, creating a constantly updated, mathematical representation of its unique life.
Dr Goult, a reader in biochemistry, said: 'This research shows that in many ways the brain resembles the early mechanical computers of Charles Babbage and his Analytical Engine. Here, the cytoskeleton serves as the levers and gears that coordinate the computation in the cell in response to chemical and electrical signalling. Like those early computation models, this discovery may be the beginning of a new understanding of brain function and in treating brain diseases.'

Gene editing technology will play a vital role in climate-proofing future crops to protect global food supplies, according to scientists at The University of Queensland.
Biotechnologist Dr Karen Massel from UQ's Centre for Crop Science has published a review of gene editing technologies such as CRISPR-Cas9 to safeguard food security in farming systems under stress from extreme and variable climate conditions.
"Farmers have been manipulating the DNA of plants using conventional breeding technologies for millennia, and now with new gene-editing technologies, we can do this with unprecedented safety, precision and speed," Dr Massel said.
"This type of gene editing mimics the way cells repair in nature."

New research from the University of Kent reveals social cohesion with immigration is best ensured through childhood exposure to diversity in local neighbourhoods, leading to acceptance of other groups.
The research, which is published in Oxford Economic Papers, builds on the Nobel Laureate economist Thomas Schelling's Model of Segregation, which showed that a slight preference by individuals and families towards their own groups can eventually result in complete segregation of communities.
Shedding new light on this issue, researchers from Kent's School of Economics have introduced the theory ...

Will we enjoy our work more once routine tasks are automated? - Not necessarily, suggests a recent study
Research conducted at Åbo Akademi University suggests that when routine work tasks are being replaced with intelligent technologies, the result may be that employees no longer experience their work as meaningful.
Advances in new technologies such as artificial intelligence, robotics and digital applications have recently resurrected discussions and speculations about the future of working life. Researchers predict that new technologies will affect, in particular, routine and structured work tasks. According to estimations, 7-35 percent ...

Home Office data shows the number of police officers voluntarily resigning from the force in England and Wales has more than doubled in the last eight years.
Scant attention has been paid to the reason for this mass exodus. Until now. Researchers from the University of Portsmouth studied government statistics, and discovered the numbers of officers voluntarily resigning from the police service is rising - from 1,158 in the year ending March 2012 to 2,363 in the year ending March 2020. The figure amounts to 1.83 per cent of the total police officer population in England and Wales up from 0.86 per cent eight years ago.
Dr Sarah Charman, from the Institute of Criminal Justice Studies at the University of Portsmouth, led the study. ...

New research will enhance corona safety during cruises and help cruise lines to again attract passengers onboard
Researchers within Cell Biology and Industrial Management at Åbo Akademi University have developed models aimed at ensuring corona safety during cruises.
The coronavirus pandemic stopped the cruise industry more or less completely. Major international cruise lines, such as Royal Caribbean Group and Carnival Corporation, largely suspended their cruises during 2020, which resulted in practically zero turnover and losses amounting to billions.
Upon assignment by Business Finland, an interdisciplinary research team has been working to find solutions for managing the current crisis ...

A lot of us recycle our old textiles, but few of us know that they are very difficult to re-use, and often end up in landfills anyway. Now, researchers at Lund University in Sweden have developed a method that converts cotton into sugar, that in turn can be turned into spandex, nylon or ethanol.

Every year, an estimated 25 million tonnes of cotton textiles are discarded around the world. In total, 100 million tonnes of textiles are thrown out. In Sweden, most of the material goes straight into an incinerator and becomes district heating. In other places, it is even worse, as clothes usually end up in landfills.
"Considering that cotton is a renewable ...

TAMPA, Fla. - Genetic alterations of the KRAS gene are some of the most common mutations in lung cancer patients, but unfortunately these patients have few effective treatment options. Drugs that target the G12C mutation in KRAS have shown some activity in lung cancer; however, alternative signaling pathways are often activated that bypass the KRAS inhibitor, resulting in drug resistance. In a new article published in Clinical Cancer Research, Moffitt Cancer Center researchers show that various subtypes of lung cancer cells activate different signaling pathways in response to KRASG12C inhibitor treatment. These results may help identify potential combination therapy approaches and guide ...

Atmospheric carbon dioxide (CO2) is a major driver of global warming, but this gas could also serve as a valuable resource. Researchers at KAUST have developed an efficient catalyst that uses light energy to convert CO2 and hydrogen into methane (CH4). This counteracts the release of CO2 when methane is burned as a fuel.
Many researchers worldwide are exploring ways to convert CO2 into useful carbon-based chemicals, but their efforts have been limited by low efficiencies that restrict the potential for large-scale application.
"Our approach is based on the synergistic combination of light and heat, known as the photothermal effect," says postdoc Diego Mateo. He explains that the heat is generated by the interaction of light with the catalyst, ...

Respiratory viruses such as SARS-CoV-2 (causing COVID-19) can often catalyse an overactive immune response that leads to a life-threatening cycle, known as a cytokine storm. Analysing cytokine responses from patients infected with SARS-CoV-2 and similar common respiratory viruses has unearthed glaringly important differences in how SARS-CoV-2 affects cytokines compared to other common respiratory viruses.
The comprehensive data resource aims to help specialists identify better treatments and diagnosis of underlying causes that can cause the deadly cytokine storm.
