Sequences in the ‘Dark Genome’ Could be Used to Diagnose Cancer Earlier

Posted by in category: biotech/medical

The human genome is primarily composed of long stretches of repeat nucleotides that do not code for protein (only about two percent of the human genomes does code for protein). This mysterious, non-protein-coding DNA was once disregarded as junk DNA, but scientists have begun to find sequences of importance within this ‘junk,’ which is now sometimes called genomic ‘dark matter.’ Some of these sequences appear to have important regulatory functions, and can control the expression of some protein-coding genes. But studying these sequences can be extremely challenging, particularly because they are not like protein-coding genes that can be studied with standard techniques.

But scientists have now found a great use for the dark genome. Reporting in Science Translational Medicine, researchers created a method to reveal elements of the dark genome in cancerous tissue and in the bloodstream, as fragments called cell-free DNA (cfDNA). These bits of DNA are lost from tumors and they move around the body in the bloodstream. This technique may eventually help scientists or clinicians identify cancer or monitor the progress of treatment.

New Protein Found to Mediate Immune Cell Response

Posted by in categories: biotech/medical, futurism

The immune system is a complex network of various cell types all working cohesively to identify and eliminate foreign invaders. Unfortunately, if a disease is strong enough or our immune system is not well equipped to accurately target the disease, we get sick until the immune system builds a strong enough immune response toward it. A great example includes vaccine biology. We are given an attenuated form of a disease and our body, not exposed to it before, will recognize the markers on the outside of the virus and make antibodies against it. Consequently, the immune system will build up a strong enough immune response to completely eradicate the disease from the body and also maintain memory cells that will instantly recognize future exposures of the same disease.

Different immune cells play various roles that effectively elicit an immune response. Innate immunity is the first barrier against disease. Cells in this barrier are non-specific and target a broad range of diseases but are less potent. Additionally, they take the protein or antigen from the disease and present it to more specific and effective immune cells in the adaptive immune system. These highly specific cells are mainly responsible for killing or lysing the disease. Cells in the adaptive immune system include T cells and B cells. T cells are a broad cell population with different responsibilities within each T cell subset. However, CD8+ T cells are the classic T cell subtype solely responsible for lysing foreign or invading cells. The field of T cell biology is ever expanding as scientists discover new ways to improve their function and effectively target disease.

A recent article published in the Journal of Immunology, by Dr. Tadashi Matsuda and others, discovered that a new protein, known as STAP-1, improves T cell activation. Matsuda, senior author on the paper, is a Professor and Principal Investigator at Hokkaido University in Japan. His work focuses on T cell biology and intracellular components of cellular immunity. Signal-Transducing Adaptor Protein-1 or STAP-1 was implicated as a mediator between intracellular proteins and eliciting an immune response. Interestingly, STAP-1 upregulates T cell receptor (TCR)-mediated T cell function and increased inflammatory response. Matsuda and others found that STAP-1 generates the activation of downstream signaling pathways associated with stronger T cell activity. While this may have seemed like a great marker to improve immune response, the team also discovered that knocking out STAP-1 reduces autoimmune disorder symptoms. Therefore, treatment application is context dependent.

Human Cerebral Organoid Implantation Alleviated the Neurological Deficits of Traumatic Brain Injury in Mice

Posted by in categories: biotech/medical, neuroscience

Traumatic brain injury (TBI) causes a high rate of mortality and disability, and its treatment is still limited. Loss of neurons in damaged area is hardly rescued by relative molecular therapies. Based on its disease characteristics, we transplanted human embryonic stem cell-(hESC-) derived cerebral organoids in the brain lesions of controlled cortical impact-(CCI-) modeled severe combined immunodeficient (SCID) mice. Grafted organoids survived and differentiated in CCI-induced lesion pools in mouse cortical tissue. Implanted cerebral organoids differentiated into various types of neuronal cells, extended long projections, and showed spontaneous action, as indicated by electromyographic activity in the grafts. Induced vascularization and reduced glial scar were also found after organoid implantation, suggesting grafting could improve local situation and promote neural repair. More importantly, the CCI mice’s spatial learning and memory improved after organoid grafting. These findings suggest that cerebral organoid implanted in lesion sites differentiates into cortical neurons, forms long projections, and reverses deficits in spatial learning and memory, a potential therapeutic avenue for TBI.

AWS Scientists Report New Qubit Can ‘Flag’ Quantum Errors

Posted by in categories: computing, quantum physics

In the race to develop powerful quantum computers, one of the biggest roadblocks has been their extreme sensitivity to errors introduced by environmental noise. Even the smallest disturbance can corrupt the delicate quantum states that form the basis of quantum computation.

Now the AWS Center for Quantum Computing team says they may have discovered a promising solution to this hurdle. The researchers report in a blog post that they have designed and demonstrated a new type of quantum bit, or qubit, that converts the majority of errors into a special class known as “erasure errors” – and these errors can be detected and fixed much more efficiently than standard quantum errors.

The team writes: “Quantum error correction is a powerful tool for combating the effects of noise. As with error correction in classical systems, quantum error correction can exponentially suppress the rate of errors by encoding information redundantly. Redundancy protects against noise, but it comes at a price: an increase in the number of physical quantum bits (qubits) used for computation, and an increase in the complexity and duration of computations.”

Harmony in Chaos: How BPD Influences Music Tastes

Posted by in category: media & arts

Summary: Recent research reveals that individuals with Borderline Personality Disorder (BPD) exhibit distinct music preferences, favoring reflective and complex genres such as classical and jazz over intense, rebellious ones.

The study, involving 549 participants, highlights how the severity of BPD symptoms influences these preferences and the psychological functions of music, emphasizing its role in emotional regulation and social connectivity.

Music’s functions act as mediators in forming these preferences, suggesting that musical tastes among individuals with BPD reflect their internal psychological needs. This insight opens new avenues for tailored music therapy interventions, promising more effective therapeutic outcomes.
