New technology developed for single-cell analysis

Posted by in category: biotech/medical

The ability to analyze the properties of individual cells is vital to broad areas of life science applications, from diagnosing diseases and developing better therapeutics to characterizing pathogenic bacteria and developing cells for bioproduction applications. However, the accurate analysis of individual cells is a challenge, especially when it comes to a cell’s biophysical properties, due to large property variations among cells even in the same cell population as well as the presence of rare cell types within a larger population.

Addressing this need, Dr. Arum Han, Texas Instruments Professor II in the Department of Electrical and Computer Engineering at Texas A&M University, together with his graduate students and postdoctoral researchers, have developed a new technology that can accurately analyze cell properties through the use of a single-cell electrorotation microfluidic device, which utilizes an electric field to probe the cell’s properties.

The technology works by using an electric field to first capture a single cell in a microfluidic device, followed by applying a rotating electric field to rotate the trapped single cell and then measuring the speed of rotation. By knowing the input electric field parameters and analyzing the rotation speed, accurately analyzing the dielectric properties of a single cell becomes possible.

Entanglement-enhanced matter-wave interferometry in a high-finesse cavity

Posted by in categories: mapping, particle physics, quantum physics

Light-pulse matter-wave interferometers exploit the quantized momentum kick given to atoms during absorption and emission of light to split atomic wave packets so that they traverse distinct spatial paths at the same time. Additional momentum kicks then return the atoms to the same point in space to interfere the two matter-wave wave packets. The key to the precision of these devices is the encoding of information in the phase ϕ that appears in the superposition of the two quantum trajectories within the interferometer. This phase must be estimated from quantum measurements to extract the desired information. For N atoms, the phase estimation is fundamentally limited by the independent quantum collapse of each atom to an r.m.s. angular uncertainty \(\Delta {\theta }_{{\rm{SQL}}}=1/\sqrt{N}\) rad, known as the standard quantum limit (SQL)2.

Here we demonstrate a matter-wave interferometer31,32 with a directly observed interferometric phase noise below the SQL, a result that combines two of the most striking features of quantum mechanics: the concept that a particle can appear to be in two places at once and entanglement between distinct particles. This work is also a harbinger of future quantum many-body simulations with cavities26,27,28,29 that will explore beyond mean-field physics by directly modifying and probing quantum fluctuations or in which the quantum measurement process induces a phase transition30.

Quantum entanglement between the atoms allows the atoms to conspire together to reduce their total quantum noise relative to their total signal1,3. Such entanglement has been generated between atoms using direct collisional33,34,35,36,37,38,39 or Coulomb40,41 interactions, including relative atom number squeezing between matter waves in spatially separated traps33,35,39 and mapping of internal entanglement onto the relative atom number in different momentum states42. A trapped matter-wave interferometer with relative number squeezing was realized in ref. 35, but the interferometer’s phase was antisqueezed and thus the phase resolution was above the SQL.

Unique Property Found in Complex Nanostructures for the First Time

Posted by in categories: engineering, nanotechnology

Researchers from North Carolina State University and The University of Texas at Austin have discovered a unique property in complex nanostructures that had previously only been seen in simple nanostructures. They have also uncovered the internal mechanics of the materials that allow for this property to exist.

The findings were reported in a recent paper that was published in the journal Proceedings of the National Academy of Sciences. The scientists found these properties in oxide-based “nanolattices,” which are tiny, hollow materials with a structure resembling that of sea sponges.

“This has been seen before in simple nanostructures, like a nanowire, which is about 1,000 times thinner than a hair,” said Yong Zhu, a professor in the Department of Mechanical and Aerospace Engineering at NC State, and one of the lead authors on the paper. “But this is the first time we’ve seen it in a 3D nanostructure.”

22-Year-Old Vulnerability Reported in Widely Used SQLite Database Library

Posted by in category: futurism

A high-severity vulnerability has been disclosed in the SQLite database library, which was introduced as part of a code change dating all the way back to October 2000 and could enable attackers to crash or control programs.

Tracked as CVE-2022–35737 (CVSS score: 7.5), the 22-year-old issue affects SQLite versions 1.0.12 through 3.39.1, and has been addressed in version 3.39.2 released on July 21, 2022.

Researchers create first quasiparticle Bose-Einstein condensate

Posted by in categories: computing, particle physics, quantum physics

Physicists have created the first Bose-Einstein condensate—the mysterious fifth state of matter—made from quasiparticles, entities that do not count as elementary particles but that can still have elementary-particle properties like charge and spin. For decades, it was unknown whether they could undergo Bose-Einstein condensation in the same way as real particles, and it now appears that they can. The finding is set to have a significant impact on the development of quantum technologies including quantum computing.

A paper describing the process of creation of the substance, achieved at temperatures a hair’s breadth from absolute zero, was published in the journal Nature Communications.

Bose-Einstein condensates are sometimes described as the fifth state of matter, alongside solids, liquids, gases and plasmas. Theoretically predicted in the early 20th century, Bose-Einstein condensates, or BECs, were only created in a lab as recently as 1995. They are also perhaps the oddest state of matter, with a great deal about them remaining unknown to science.

This is how close we are to biological immortality

Posted by in categories: biotech/medical, life extension

Extending the limit of the human lifespan. The first immortal human has already been born.
“The first human to live to 1,000 has already been born” – Dr. Aubrey de Grey. How far are we in understanding aging and death? Do we have to age or is it a matter of a choice? What is the future of immortality? Is it possible to be immortal and if yes — how far are we in implementing medical treatment and technology that can forestall this natural process we have always thought “is just how life is”.
In this video I am reviewing the cutting-edge technologies and the pioneers in the field of extending life expectancy and reaching immortality eventually. Hint: is it closer than you might imagine!
