American and Danish scientists did not expect to make a surprising new discovery when they chose to remove the brain from a cadaver by cutting off the entire head.
Normally, researchers just remove the brain, but by cutting off the entire head, it revealed a layer of cells not previously discovered: a fourth meninge that undoubtedly plays an important role in the brain’s immune system, claims the team from the University of Copenhagen and the University of Rochester.
“When you want to examine the brain, you usually take the brain out. Doing so destroys the membrane. Therefore, it has not been possible to see it,” says Professor Maiken Nedergaard to Science.
Better understanding of how brain diseases work
Thanks to the discovery, researchers now hope to better understand how, for example, Alzheimer’s and multiple sclerosis work.
The presence of a fourth opinion in the brain’s immune system redraws the map. Scientists have already established that the fourth sense, which they have named ‘SLYM’, has several functions. It divides the fluid in the brain into two compartments, so that there is dirty fluid in one and clean fluid in the other.
But if the membrane breaks, the liquids mix together. It can be problematic and cause diseases such as Alzheimer’s and sclerosis, because it can lead waste materials back into the brain.
Textbooks must be rewritten with the discovery, which will enable a better understanding of all brain diseases in the future.
New world record for DTU researchers
DTU Physics researchers created the smallest record in the world just in time for Christmas. The researchers carved a single one using the first 25 seconds of the Christmas classic ‘Rocking Around the Christmas Tree’ using a new nano-sculpting machine called the Nanofrazor.
First driverless catamaran to cross the Limfjord
In the harbor of Aalborg, a green electric-powered catamaran has taken its maiden voyage across the Limfjord without a captain at the helm. The marine industry, with the help of DTU, has been working on the project since 2017, using AI technology to guide the harbor bus.
Vitamin D plays an important role in the fight against tuberculosis
Thanks to a very special patient who was born with a mutation that means she does not respond to vitamin D, researchers were able to monitor the important role that the vitamin plays when the immune system fights tuberculosis. Every year, more than 1.5 million people die from this disease – especially in the southern hemisphere.
Ancient fish are the key to restoring a beating heart
Thanks to the fossil of a 400-million-year-old fish, scientists found a way to understand how stem cells work. Danish scientists, who have been working on the case for some time, claim that the new knowledge may enable them to help patients whose organs fail in the future.
ADHD drug prescriptions for youth increased during the pandemic – investigation
According to a study by the University of Southern Denmark, the number of five to 24-year-olds prescribed ADHD medication and antidepressants increased by 18 percent during the pandemic until June 2022.
Antimicrobial resistance detailed worldwide in wastewater analyses
Analyzes of waste water do not lie. Between 2016 and 2019, researchers mapped the prevalence of antimicrobial resistant genes in 243 cities in 101 countries, and Denmark was among the best. According to the study, Peru, Uganda and Cambodia were the worst countries.
Breakthrough for wolf monitoring in Denmark
In West Jutland, a male wolf has been given a GPS collar by Danish researchers for the very first time. The GPS should help them monitor the development of the wolf population in the country and where they are located. The researchers have been waiting since 2018 to get one.
Being rich means less time in the kitchen
According to a study by the University of Copenhagen, the richer we are, the less home-cooked food we prepare. Indians spend about 74 minutes in the kitchen every day, but Danes only 47. Americans, who are one of the richest people, spend less than 30 minutes a day.
