Scientists make progress in understanding the gut microbiome’s role in individual response to diet

Posted by in category: food

A new study, led by Dr. Dan Knights from the University of Minnesota (USA), has found that the gut microbiome responds more to particular foods than to combinations of nutrients and that microbiome responses to diet are personalized.

The researchers studied the impact of habitual diet on the gut microbiome in 34 subjects for 17 consecutive days. Both the fecal microbiome and the participants’ diet were sampled every day through shotgun metagenomic sequencing and daily 24-hour dietary records, respectively.

Although the relative abundance of gut microbial species showed a high variation within and between individuals, functional traits tended to remain stable across individuals. In contrast, a specific group of functions related to stress response, the conversion of nitrate to nitrogen and the conversion of formate to methane showed a high interindividual variability that did not correlate with nutrient and food intake.

Bioengineered Organs: Could Change be the horizon?

Posted by in categories: bioengineering, biotech/medical

The science of tissue engineering has been constructed on a foundation of a very simple concept; take out the patient’s own cells, grow them in a sterile environment similar to that of a human body and infuse them on a scaffolding material to provide 3-dimensional support. With this recipe, you may have your own laboratory-grown organ ready! It is interesting to note that quite a few patients have experienced the benefits of this fastest growing technology. Could change be on the horizon?

Introduction

Various scientific investigations have been frequently hailed as putting forth a novel yet a breakthrough treatment to change the meaning of lives of many patients, who have been suffering from degenerative diseases since long. However, it should be noted that researchers have to travel a really long road to turn a laboratory invention into viable clinical modalities. In this regard, current medical issues associated with gastrointestinal functioning are marred with various challenges; new solutions to take over the control are sorely needed.

Japan’s Hayabusa2 probe makes ‘perfect’ touchdown on asteroid

Posted by in categories: materials, space

Japan’s Hayabusa2 probe made a “perfect” touchdown Thursday on a distant asteroid, collecting samples from beneath the surface in an unprecedented mission that could shed light on the origins of the solar system.

“We’ve collected a part of the solar system’s history,” project manager Yuichi Tsuda said at a jubilant press conference hours after the successful landing was confirmed.

“We have never gathered sub-surface material from a celestial body further away than the Moon,” he added.

At Last, AI beats professionals in six-player poker

Posted by in category: robotics/AI

An artificial intelligence program developed by Carnegie Mellon University in collaboration with Facebook AI has defeated leading professionals in six-player no-limit Texas hold’em poker, the world’s most popular form of poker.

The AI, called Pluribus, defeated professional Darren Elias, who holds the record for most World Poker Tour titles, and Chris “Jesus” Ferguson, winner of six World Series of Poker events. Each pro separately played 5,000 hands of poker against five copies of Pluribus.

In another experiment involving 13 pros, all of whom have won more than $1 million playing poker, Pluribus played five pros at a time for a total of 10,000 hands and again emerged victorious.

Quantum sensor breakthrough using naturally occurring vibrations in artificial atoms

Posted by in categories: particle physics, quantum physics

A team of scientists, led by the University of Bristol, have discovered a new method that could be used to build quantum sensors with ultra-high precision.

When emit , they do so in discrete packets called photons.

When this light is measured, this discrete or ‘granular’ nature leads to especially low fluctuations in its brightness, as two or more photons are never emitted at the same time.

Scientists discover how to ‘lock’ heat in place using quantum mechanics

Posted by in categories: engineering, quantum physics

A ground-breaking study conducted by researchers from the National University of Singapore (NUS) has revealed a method of using quantum mechanical wave theories to “lock” heat into a fixed position.

Ordinarily, a source of diffuses through a conductive material until it dissipates, but Associate Professor Cheng-Wei Qiu from the Department of Electrical and Computer Engineering at the NUS Faculty of Engineering and his team used the principle of anti-parity-time (APT) symmetry to show that it is possible to confine the heat to a small region of a metal ring without it spreading over time.

In the future, this newly demonstrated phenomenon could be used to control in sophisticated ways and optimize efficacy in systems that need cooling. The results of the study were published on 12 April 2019 in the journal Science.

Secure quantum communications in the microwave range for the first time

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

Mikel Sanz, of the Physical Chemistry Department of UPV/EHU, leads the theoretical group for an experiment published by the prestigious journal, Nature Communications. The experiment has managed to prepare a remote quantum state; i.e., absolutely secure communication was established with another, physically separated quantum computer for the first time in the microwave regime. This new technology may bring about a revolution in the next few years.

Within the greater European project of the Quantum Flagship, spearheaded by Mikel Sanz—researcher of the QUTIS Group of the UPV/EHU Physical Chemistry Department—an experiment has been conducted in collaboration with German and Japanese researchers who have managed to develop a protocol for preparing a remote quantum state while conducting in the regime, “which is the frequency at which all quantum computers operate. This is the first time the possibility of doing so in this range has been examined, which may bring about a revolution in the next few years in the field of secure quantum communication and quantum microwave radars,” lead researcher in this project Mikel Sanz observes.

The preparation of a remote quantum state (known as remote state preparation) is based on the phenomenon of quantum entanglement, where sets of entangled particles lose their individuality and behave as single entities, even when spatially separated. “Thus, if two computers share this quantum correlation, performing operations on only one of them can affect the other. Absolutely secure communication can be achieved,” Sanz explains.
