Is it just noise, a side effect of evolution, or does it have functions?

Key Points: 
  • Is it just noise, a side effect of evolution, or does it have functions?
  • A research team at NYU Langone Health sought to answer the question by creating a large, synthetic gene, with its DNA code in reverse order from its natural parent.
  • Then they put synthetic gene into yeast and mouse stem cells and watched transcription levels in each.
  • The study authors use yeast cells to assemble long DNA sequences in a single step, and then deliver the them into mouse embryonic stem cells.

Quantum dots are part of a revolution in engineering atoms in useful ways – Nobel Prize for chemistry recognizes the power of nanotechnology

The 2023 Nobel Prize for chemistry isn’t the first Nobel awarded for research in nanotechnology.

Key Points: 
  • The 2023 Nobel Prize for chemistry isn’t the first Nobel awarded for research in nanotechnology.
  • But it is perhaps the most colorful application of the technology to be associated with the accolade.
  • This year’s prize recognizes Moungi Bawendi, Louis Brus and Alexei Ekimov for the discovery and development of quantum dots.
  • Quantum dots brilliantly fluoresce: They absorb one color of light and reemit it nearly instantaneously as another color.

Skip chemical bonds, rely on quantum physics

    • For instance, some of the earliest dyes started with a clear substance such as analine, transformed through chemical reactions to the desired hue.
    • Rather than depending on chemical bonds to determine the wavelengths of light they absorb and emit, they rely on very small clusters of semiconducting materials.
    • Early quantum dots were often based on cadmium selenide for instance – the component materials of which are toxic.
    • And yet, quantum dots are a pivotal part of a technology transition that’s revolutionizing how people work with atoms and molecules.

‘Base coding’ on an atomic level

    • This concept is intuitive when it comes to computing, where programmers use the “base code” of 1,s and 0’s, albeit through higher level languages.
    • This ability to work with base codes also extends to the material world.
    • Here, the code is made up of atoms and molecules and how they are arranged in ways that lead to novel properties.
    • Bawendi, Brus and Ekimov’s work on quantum dots is a perfect example of this form of material-world base coding.

New research reveals that Ötzi the iceman was bald and probably from a farming family – what else can DNA uncover?

This amazing find would subsequently become known as Ötzi the Iceman.

Key Points: 
  • This amazing find would subsequently become known as Ötzi the Iceman.
  • His body and belongings were extensively studied, prompting numerous questions: what was he doing here?
  • His unique preservation enabled the sequencing of Ötzi’s whole genome – the complete “instruction booklet” for building a human.
  • But it was enough for a team led by Turi King at the University of Leicester to extract fragments of DNA from them.

Crime scene samples

    • Sequencing a genome, which comprises billions of DNA bases, enables scientists to evaluate regions of the human genome that contribute to appearance.
    • For more than 30 years, forensic scientists have looked at specific highly variable regions in DNA to match these to crime scene samples, or to relatives of a suspect or victim.
    • So how likely is it that DNA from such a sample could accurately paint a picture of me?
    • Can forensic scientists build a kind of identikit photo from a crime scene DNA sample?
    • Hair colour can be predicted from DNA, but darker shades of hair are more accurately predicted than blonde hair.

Environmental factors

    • Commercially sold laboratory kits such as Hirisplex can simultaneously evaluate several DNA regions to predict the hair and eye colour from a biological sample.
    • However, unlike eye colour, hair colour prediction from DNA is only of value until midlife, when the natural processes of ageing lead to greying or white hair.
    • These processes also lead to hair loss in some people and more than 300 gene variants have been linked to baldness.
    • More representative data from the rest of the world will therefore enhance studies in forensic archaeology, such as the Ötzi research.

Over 3,000 significant correlations were found linking reductions in DNA methylation of various CpGs and cognitive, biomarker and neuroimaging endpoints.

Key Points: 
  • Over 3,000 significant correlations were found linking reductions in DNA methylation of various CpGs and cognitive, biomarker and neuroimaging endpoints.
  • I have prepared this letter to shareholders to provide an update that synthesizes all the information that we have released and presented at recent medical conferences.
  • NE3107 reduced CSF phospho-tau levels by -1.66 pg/mL (p=0.0343) and the ratio of p-tau to amyloid beta 42 (Aβ42) by -0.0024 (p=0.0401).
  • P-tau and Aβ are traditional biomarkers of AD progression and have been the focus for AD researchers for decades.
