The very first moments of the Universe can be reconstructed mathematically even though they cannot be observed directly. Physicists from the Universities of Göttingen and Auckland (New Zealand) have greatly improved the ability of complex computer simulations to describe this early epoch. They discovered that a complex network of structures can form in the first trillionth of a second after the Big Bang. The behavior of these objects mimics the distribution of galaxies in today’s Universe. In contrast to today, however, these primordial structures are microscopically small. Typical clumps have masses of only a few grams and fit into volumes much smaller than present-day elementary particles. The results of the study have been published in the journal Physical Review D.

You are constantly adjusting your walking parameters based on the feedback you’re getting from your environment. You walk differently on a soft surface, you prepare yourself before using stairs. Meanwhile robots cannot really do that, especially exoskeletons. These robotic legs could help disabled people walk again on their own, but how could they prepare to stop, climb stairs, make a sharp turn? Scientists believe that in the future exoskeletons are going to be smart thanks to cameras and artificial intelligence.

Currently exoskeletons need to be controlled manually via smartphone applications or joysticks. This is less than ideal, because the disabled person can’t walk as intuitively as an able-bodied person can. And his or her hands are always occupied with these controls. That kind of a cognitive load is extremely tiring and can be dangerous over time. Could you imagine needing to take out your phone every time you want to climb a set of stairs or walk through a strip of sand? Scientists want to borrow a page from a book about autonomous cars and therefore are optimizing AI computer software to process the video feed to accurately recognize stairs, doors and other features of the surrounding environment.

This would be huge.

With bees in decline globally, one Israeli company has developed a technological solution that could restore their populations.

A force is something which tends to change the state of rest or state of motion, or size, shape, the direction of motion of a body, etc… There are four fundamental forces: gravitational, electromagnetic, strong nuclear and weak nuclear forces. These forces are responsible for all possible interactions that can take place in this universe, from planets orbiting a star to protons and neutrons confined in the nucleus of an atom. In classical physics, the assumption was that an imaginary field exists, through which a force can be transmitted. But with the advent of quantum mechanics, this idea was changed radically. A field exists, but that is a quantum field. The field vibrates gently, and these vibrations give rise to particles and their corresponding antiparticle partners, i.e., particles with opposite charge. But these particles can exist for a limited amount of time. What gives rise to forces then? Particles called bosons. Bosons, named after Indian physicist Satyendra Nath Bose, are particles, the exchange of which give rise to forces. Bosons, along with the fermions (which make up matter), are referred to as elementary particles [1].

In quantum mechanics, energy can be temporarily ‘borrowed’ from a particle. But, as per Heisenberg’s uncertainty principle, the greater the amount of energy you ‘borrow’, the sooner you must return it [2].

The team used artificial intelligence techniques to analyze the pH inside cells and determine if they were cancer cells.

Summary: Mimicking a muscular stress system can provide neuroprotection against aging in both the brain and retina. The signal helps prevent the buildup of misfolded protein aggregates.

How do different parts of the body communicate? Scientists at St. Jude are studying how signals sent from skeletal muscle affect the brain.

Welcome to 2021! We left 2020 with COVID-19, yet it continues into the new year; on top of it the virus produced a much more contagious asshole!!!

The evolved strain of COVID-19, known as B.1.1.7, has shown itself in the USA as well as other countries.

Two male members of the Colorado National Guard tested positive for the new strain — referred to as B.1.1.7 or VUI-202012/01 — and neither reported international travel. At least one of the two men is in his 20s.

The more diverse your microbiome, the healthier you are. While diet is often presented to be the deciding factor in your microbiome diversity, the story isn’t so simple. Studies show that nutrition can determine 5%-20% of your gut microbiome, which is enough to concern yourself with, but not enough to rely on as the sole determinant of your microbiome’s health.

Does your gut microbiome have an impact on your longevity? And if so, what can you to live longer? It’s complicated.
