Study examines how our native language shapes our brain wiring

Posted by in categories: biotech/medical, neuroscience

Scientists at the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig have found evidence that the language we speak shapes the connectivity in our brains that may underlie the way we think. With the help of magnetic resonance tomography, they looked deep into the brains of native German and Arabic speakers and discovered differences in the wiring of the language regions in the brain.

Xuehu Wei, who is a doctoral student in the research team around Alfred Anwander and Angela Friederici, compared the of 94 of two very and showed that the language we grow up with modulates the wiring in the brain. Two groups of native speakers of German and Arabic respectively were scanned in a imaging (MRI) machine.

The high-resolution images not only show the anatomy of the brain, but also allow to derive the connectivity between the using a technique called diffusion-weighted imaging. The data showed that the axonal white matter connections of the language network adapt to the processing demands and difficulties of the mother tongue.

Scientists Identify New Schizophrenia Risk Genes in First-of-Its-Kind Study

Posted by in categories: biotech/medical, neuroscience

Two newly discovered genes have been linked to schizophrenia while a previously known gene associated with schizophrenia risk has also been linked to autism in a massive new study.

Scientists say the findings increase our understanding of brain diseases and could lead to new treatment targets.

Four Walls Good, Two Walls Bad for Confined Cells

Posted by in category: biotech/medical

Segregation of chromosomes in dividing cells can be disrupted if the cells are constrained by their surroundings.

One of the aberrant features of cancer cells is a failure to distribute chromosomes properly when the cells divide. Researchers have now found that a specific problem with the chromosome-distribution machinery can become more common in cancer cells confined within shallow microscopic channels—but also that, surprisingly, increasing the physical constraints can suppress these errors [1]. Such confinement mimics the effects of crowding by surrounding cells in a tumor, and the researchers believe the results might help to explain what goes awry in cancers and perhaps offer clues to how it might be put right.

In a healthy, dividing cell, after the genome is replicated, the chromosomes are segregated into two groups. Both groups are bound to the mitotic spindle, a bundle of aligned filaments (called microtubules) that are pinched together at the ends into structures called poles. The chromosomes are then drawn along the microtubules toward the poles. A key cause of improper chromosome segregation in cancer cells is the formation of spindles with more than two poles. Multipolar spindle formation inside living organisms may differ from the phenomenon when observed in cells grown in a dish [2], so it is possible that the confining effect of the surrounding cells in a tissue has some influence on this process.

This nanoparticle could be the key to a universal covid vaccine

Posted by in categories: biotech/medical, nanotechnology

Year 2022 😗😁 Basically more thought on this virus seems more like a foglet biotechnology so it would stand to reason that a nanotechnology with biotechnology could solve the universal vaccine.

Ending the covid pandemic might well require a vaccine that protects against any new strains. Researchers may have found a strategy that will work.

Year 2022 This is their published work on the universal vaccine of the covid 19.

A mosaic sarbecovirus nanoparticle protects against SARS-2 and SARS-1, whereas a SARS-2 nanoparticle only protects against SARS-2.

Can exercise affect the progression of Alzheimer’s disease?

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

(NewsNation) — Studies have shown that Alzheimer’s may become the defining disease of the baby boomer generation.

According to The Alzheimer’s Association, the number of people age 65 and over living with Alzheimer’s now is nearly 7 million. That number is expected to rise to over 13 million by 2050.

Physician and best-selling author Dr. Ian Smith says it’s not known exactly what causes Alzheimer’s.

Tomorrow Biostasis: The Berlin Startup That Wants to Bring You Back from the Dead

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

What if death was not the end? What if, instead of saying our final goodbyes to loved ones, we could freeze their bodies and bring them back to life once medical technology has advanced enough to cure their fatal illnesses? This is the mission of Tomorrow Biostasis, a Berlin-based startup that specializes in cryopreservation.

Cryopreservation, also known as biostasis or cryonics, is the process of preserving a human body (or brain) in a state of suspended animation, with the hope that it can be revived in the future when medical technology has advanced enough to treat the original cause of death. This may seem like science fiction, but it is a legitimate scientific procedure, and Tomorrow Biostasis is one of the few companies in the world that offers this service.

Dr Emil Kendziorra, co-founder and CEO of Tomorrow Biostasis explained that the goal of cryopreservation is to extend life by preserving the body until a cure can be found for the original illness. He emphasized that cryopreservation is not a form of immortality, but rather a way to give people a second chance at life.
