Be the first to comment on “Quantum Destabilization of a Water Sandwich – Laws of Classical Physics Break Down”

Posted by in categories: food, quantum physics, sustainability

From raindrops rolling off the waxy surface of a waterlily leaf, to the efficiency of desalination membranes, interactions between water molecules and water-repellent “hydrophobic” surfaces are all around us. The interplay becomes even more intriguing when a thin water layer becomes sandwiched between two hydrophobic surfaces, KAUST researchers have shown.

In the early 1980s, researchers first noted an unexpected effect when two hydrophobic surfaces were slowly brought together in water. “At some point, the two surfaces would suddenly jump into contact—like two magnets being brought together,” says Himanshu Mishra from KAUST’s Water Desalination and Reuse Center. Mishra’s lab investigates water at all length scales, from reducing water consumption in agriculture, to the properties of individual water molecules.

How we Benefit from Getting our Genomes Sequenced

Posted by in categories: biotech/medical, finance, food, genetics, habitats, health, internet, mobile phones

When the first smartphones arrived, few people understood how they would change our reality. Today, our internet-connected mobile device maps our travel, manages our finances, delivers our dinner, and connects us to every corner of human knowledge. In less than a generation, it has become almost an extension of our central nervous system — so indispensable that we can’t imagine leaving home without it to guide us.

We are about to embark on another journey even more important to every individual and to human society. We are entering the age of genomics, an amazing future that will dramatically improve the health outcomes of people across the planet. Soon, we won’t be able to imagine a time when we left home without knowledge of our genome to guide us.

Haematopoietic stem cells in perisinusoidal niches are protected from ageing

Posted by in categories: biotech/medical, life extension

With ageing, intrinsic haematopoietic stem cell (HSC) activity decreases, resulting in impaired tissue homeostasis, reduced engraftment following transplantation and increased susceptibility to diseases. However, whether ageing also affects the HSC niche, and thereby impairs its capacity to support HSC function, is still widely debated. Here, by using in-vivo long-term label-retention assays we demonstrate that aged label-retaining HSCs, which are, in old mice, the most quiescent HSC subpopulation with the highest regenerative capacity and cellular polarity, reside predominantly in perisinusoidal niches. Furthermore, we demonstrate that sinusoidal niches are uniquely preserved in shape, morphology and number on ageing. Finally, we show that myeloablative chemotherapy can selectively disrupt aged sinusoidal niches in the long term, which is linked to the lack of recovery of endothelial Jag2 at sinusoids. Overall, our data characterize the functional alterations of the aged HSC niche and unveil that perisinusoidal niches are uniquely preserved and thereby protect HSCs from ageing.

Determining the shapes of atomic clusters

Posted by in categories: mathematics, nanotechnology, particle physics, robotics/AI

Too large to be classed as molecules, but too small to be bulk solids, atomic clusters can range in size from a few dozen to several hundred atoms. The structures can be used for a diverse range of applications, which requires a detailed knowledge of their shapes. These are easy to describe using mathematics in some cases; while in others, their morphologies are far more irregular. However, current models typically ignore this level of detail; often defining clusters as simple ball-shaped structures.

In research published in The European Physical Journal B, José M. Cabrera-Trujillo and colleagues at the Autonomous University of San Luis Potosí in Mexico propose a new method of identifying the morphologies of atomic clusters. They have now confirmed that the distinctive geometric shapes of some clusters, as well as the irregularity of amorphous structures, can be fully identified mathematically.

The insights gathered by Cabrera-Trujillo’s team could make it easier for researchers to engineer atomic clusters for specific applications. These could include nanoparticles containing two different metals, which are highly effective in catalysing chemical reactions. Their updated methods provided new ways to determine the structural properties of clusters, the ways in which they convert energy to different forms, and the potential forces between atoms. The technique was also able to distinguish the surrounding environments of atoms in the cores of clusters, and on their surfaces. Ultimately, this allowed the researchers to distinguish between distinctive shapes, including icosahedrons, octahedrons, and simple pancakes. They were also able to identify amorphous shapes, which contain no discernible mathematical order.

Scientists develop industrial-strength adhesive which can be unstuck in magnetic field

Posted by in categories: chemistry, mobile phones, sustainability, transportation

Researchers at the University of Sussex have developed a glue which can unstick when placed in a magnetic field, meaning products otherwise destined for landfill, could now be dismantled and recycled at the end of their life.

Currently, items like mobile phones, microwaves and car dashboards are assembled using adhesives. It is a quick and relatively cheap way to make products but, due to problems dismantling the various materials for different recycling methods, most of these products will be destined for landfill.

However, Dr. Barnaby Greenland, Lecturer in Medicinal Chemistry, working in conjunction with Stanelco RF Technologies Ltd and Prof Wayne Hayes at the University of Reading, may have found a solution.

Alien abduction claims examined

Posted by in categories: biotech/medical, sex, space travel

Mark H. says he was abducted by aliens. He clearly remembers awakening one night, unable to move anything but his eyes. He saw flashing lights, heard buzzing sounds, experienced feelings of levitation, and felt electric tingling sensations. Most terrifying were the nonhuman figures he saw by his bed.

Mark believes they were aliens.

Later, he underwent hypnosis to try to recall exactly what had happened to him. Under hypnosis, Mark remembered being whisked through an open window to a large spaceship. He was very frightened when aliens took him into some kind of medical examining room. There he had sex with one of them.
