A collaborative study published today in the journal Cell Reports provides evidence for a new molecular cause for neurodegeneration in Alzheimer’s disease. The study, led by researchers at Baylor College of Medicine and the Jan and Dan Duncan Neurological Research Institute at Texas Children’s Hospital, integrates data from human brain autopsy samples and fruit flies to reveal a novel mechanistic link between alterations in RNA splicing and tau-mediated neurodegeneration in Alzheimer’s disease.

“Cells carry out their functions by producing specific proteins encoded in their genes. To produce proteins, genes encoded in the DNA are first transcribed into RNA molecules, which subsequently are translated into proteins,” said corresponding author Dr. Joshua Shulman, associate professor of neurology, neuroscience and molecular and human genetics at Baylor and investigator at the Jan and Dan Duncan Neurological Research Institute.

In this study, Shulman and his colleagues investigated a molecular mechanism called RNA splicing that is involved in the production of mature RNA molecules necessary to produce working proteins. They looked into the possibility that aggregates of tau protein within neurons, a key marker of Alzheimer’s disease, interfered with RNA splicing.

Researchers led by Delft University of Technology personnel have made two steps in the conversion of quantum states between signals in the microwave and optical domains. This is of great interest for connecting future superconducting quantum computers into a global quantum network. This week they report on their findings in Nature Physics and in Physical Review Letters.

Conversion between signals in the microwave and optical domains is of great interest, particularly for connecting future superconducting quantum computers into a global quantum network. Many leading efforts in quantum technologies, including superconducting qubits and quantum dots, share quantum information through photons in the microwave regime. While this allows for an impressive degree of quantum control, it also limits the distance the information can realistically travel before being lost to a mere few centimeters.

At the same time, the field of optical quantum communication has already seen demonstrations over distance scales capable of providing real-world applications. By transmitting information in the optical telecom band, fiber-based quantum networks over tens or even hundreds of kilometers can be envisaged. “In order to connect several quantum computing nodes over large distances into a quantum internet, it is therefore vital to be able to convert quantum information from the microwave to the optical domain, and back,” says Prof. Simon Groeblacher of Delft University of Technology. “This will not only be extremely interesting for quantum applications, but also for highly efficient, low-noise conversion between classical optical and electrical signals.”

Controlling the interactions between light and matter has been a long-standing ambition for scientists seeking to develop and advance numerous technologies that are fundamental to society. With the boom of nanotechnology in recent years, the nanoscale manipulation of light has become both, a promising pathway to continue this advancement, as well as a unique challenge due to new behaviors that appear when the dimensions of structures become comparable to the wavelength of light.

Scientists in the Theoretical Nanophotonics Group at The University of New Mexico’s Department of Physics and Astronomy have made an exciting new advancement to this end, in a pioneering research effort titled “Analysis of the Limits of the Near-Field Produced by Nanoparticle Arrays,” published recently in the journal, ACS Nano, a top journal in the field of nanotechnology. The group, led by Assistant Professor Alejandro Manjavacas, studied how the optical response of periodic arrays of metallic nanostructures can be manipulated to produce strong electric fields in their vicinity.

The arrays they studied are composed of silver nanoparticles, tiny spheres of silver that are hundreds of times smaller than the thickness of a human hair, placed in a repeating pattern, though their results apply to nanostructures made of other materials as well. Because of the strong interactions between each of the nanospheres, these systems can be used for different applications, ranging from vivid, high-resolution color printing to biosensing that could revolutionize healthcare.

Salamanders are renowned for their regenerative capabilities, such as growing back entire limbs. We can’t pull off this biological trick, but new research highlights a previously unknown regenerative ability in humans—one held over from our evolutionary past.

Our bodies have retained the capacity to repair injured or overworked cartilage in our joints, says new research published today in Science Advances. Remarkably, the mechanics of this healing process are practically the same as what’s used by amphibians and other animals to regenerate lost limbs, according to the study.

Despite the level of understanding and knowledge the world has about so many things, everyone is still getting excited about new discoveries and this one is no exception. A rare meteorite, which was found in Siberia, contains a crystal, or at least what appears to be a crystal. The mineral itself is quite rare as well and is also a mystery. While crystal is the term used to describe it, no one’s sure what it actually is but here’s what they know so far:

A fair few years ago now, scientists discovered a small piece of a mineral that was created shortly after the solar system, some four and half billion years ago. The mineral was brought to Earth by the Khatyrka meteorite, which landed in Eastern Siberia. Obviously, a 4 billion-year-old mineral would be incredibly interesting to almost anyone, but not so much in this case. It was still quite intriguing but not for its sheer age, as many would expect, but for its atomic structure instead.

The structure that this mineral possesses is one that has never before been found in nature, although it has been created in laboratory environments. It was referred to as a quasicrystal because from the exterior it resembles a crystal, but on the inside, it’s a whole other kettle of fish.

It is the name of the unknown theory of everything which would combine all five Superstring theories and the Supergravity at 11 dimensions together.

The theory requires mathematical tools which have yet to be invented in order to be fully understood. The theory was proposed by Edward Witten.

The following article is somewhat technical in nature, see M-theory simplified for a less technical article.

The faint, 12-billion-year-old signal would lead scientists to the very first stars and illuminate the origins of the modern universe, dark matter, and, well, everything.

What would it be like to experience the 4th dimension?
