Summary: Researchers shed new light on the molecular and genetic basis of long-term memory formation in the brain. A new study reveals a single stimulation to the synapses of hippocampal neurons triggered numerous cycles where the memory-coding Arc gene produced mRNA molecules that were then translated into synapse-strengthening Arc proteins. From the findings, researchers determined a novel feedback loop that helps explain how short-lived mRNA and proteins create long-term memories in the brain.

Summary: An international team of scientists has identified a gene in the brain responsible for anxiety symptoms and found that modifying the gene can reduce anxiety levels, offering a novel drug target for anxiety disorders. The discovery highlights a new amygdala miR483-5p/Pgap2 pathway that regulates the brain’s response to stress and provides a potential therapeutic approach for anxiety disorders.

A gene in the brain driving anxiety symptoms has been identified by an international team of scientists. Critically, modification of the gene is shown to reduce anxiety levels, offering an exciting novel drug target for anxiety disorders.

An anti-cancer gel promises to wipe out glioblastoma permanently, a feat that’s never been accomplished by any drug or surgery. So what makes this gel so special?

Scientists at Johns Hopkins University (JHU) have developed a novel gel that both eliminates brain cancer (glioblastoma) and keeps it from recurring. When they tested this anti-cancer gel on mice with glioblastoma, surprisingly, all the mouse models were cured of the illness.

A new project called Progression Assessment in Neurodegenerative Disorders of Aging or PANDA aims to detect subtle changes in a person’s sleep patterns that may indicate the onset of Alzheimer’s or Parkinson’s disease. The collaboration of this four-year project involves Rigshospitalet University, Denmark’s Aarhus University, and MedTech company T&W Engineering. The project has received funding of DKK 15 million to develop and test a small earbud-like experimental device that can detect the early signs of these diseases.

The Ear-EEG Technology

Unlike the traditional sleep-monitoring systems that require a person to stay in a clinic with multiple electrodes attached to their body, the ear-EEG allows for comfortable, long-term use at home. The device monitors electrical activity in the brain by measuring tiny voltage changes on the skin surface within the ear canal. It is also equipped with an oximeter for measuring blood oxygen levels, a microphone for monitoring respiration and heart rate, and a thermometer for measuring body temperature.

Scientists have successfully grown a monkey brain to be larger than its regular size by using a human brain gene, replicating that historical moment when humans and primates were set apart.

A study reflects on how these plastic particles can increase the risk of neuroinflammation and neurodegeneration.

We have known for a while that microplastics are in our bloodstreams, making their way into our bodies through daily consumables like milk and meat. The foreign presence of micro and nano-plastic particles (MNPs) in our bodies is dangerous for obvious reasons, and they can potentially reach remote locations and penetrate living cells.

In a scary confirmation of this potentiality, a new study has found that polystyrene, a widely-used plastic found in food packaging, could be detected in the brain just two hours after ingestion.

Scientists at Johns Hopkins University have developed a revolutionary gel that cured 100% of mice with aggressive brain cancer, offering new hope for treating glioblastoma, one of the deadliest brain tumors in humans.

Last 2020, scientists were able to pick up distinct brain signals that had never been observed before. Such findings hint at how the brain is a more powerful computational device than previously thought.

The researchers found those who showed positive age beliefs were 30% more likely to recover from cognitive impairment than those who held negative age beliefs, irrespective of the severity of the cognitive decline. The time for recovery was also quicker in people with positive age beliefs.

They also found that the participants who stayed positive about aging were less likely to develop mild cognitive impairment over 12 years.

It is widely believed that memory loss associated with aging is irreversible. However, a new study says people who embrace aging positively may recover from cognitive decline.
