Participants were taken in a cable car to a high altitude laboratory at the top of Aiguille du Midi mountain in Chamonix in France.
How high altitudes affect people's breathing and its coordination with the heart beat is due to genetic differences say researchers.

Clear physiological differences have already been demonstrated between people living in the Himalayas and Andes compared with people living at sea level, revealing an evolutionary adaptation in the control of blood flow and oxygen delivery to the brain and the rest of the body.

Now an international team led by Professor Aneta Stefanovska of Lancaster University has identified genes that are related to cardiorespiratory function during so-called acute periodic breathing. Their report is published in the Journal of Physiology.

Periodic breathing (PB) occurs in most humans at high altitudes and is characterised by periodic alternations between hyperventilation (too-fast breathing) and apnoea (no breathing). The altered respiratory pattern due to PB is accompanied by changes in heart rate and blood flow.

Breathing, ECG of the heart and microvascular blood flow were simultaneously monitored for 30 minutes in 22 healthy male subjects, with the same measurements repeated under normal and low oxygen levels, both at real and simulated altitudes of up to 3800m.

Hemp is the new plastic: 3 companies that ditched regular plastic for hemp plastic

Hemp
Three U.S. companies have quietly embraced the use of hemp plastic into their business models, and their products have already hit the market.

Plastic has become the most visible pollution issue facing the world. The Great Pacific Garbage Patch, now twice the size of Texas, is the subject of many environmental cleanup efforts while plastic waste from all over the world continues to pour into our oceans at an alarming rate. Governments around the world are now debating laws restricting plastic use, with many U.S. cities and states passing bans on single-use plastic bags and straws.

As the plastic problem rages on unabated, some companies are taking it upon themselves to come up with new solutions to tackle the issue. With the passage of the 2018 U.S. Farm Bill, which legalized industrial hemp, a fresh look is being given to the versatile commodity for use in everyday items, including eco-friendly plastic. The Mind Unleashed caught up with three U.S. companies who have quietly embraced the use of hemp plastic into their business models, and their products have already hit the market.

Hemolithin: Extraterrestrial protein discovered in meteorite for the first time

The discovery of a novel protein in a meteorite strengthens the argument that life's building blocks arrived from space
Scientists have discovered a full, previously-unknown protein inside a meteorite for the first time. Named hemolithin, the new protein contains iron and lithium and may play an important role in seeding life on habitable planets like Earth.

Scientists from Harvard, PLEX Corporation and Bruker Scientific discovered hemolithin in a meteorite known as Acfer 086, which was found in Algeria in 1990. It's a fairly small protein, made up mostly of the amino acid glycine and capped with iron, oxygen and lithium atoms at the ends. While all those pieces are well-known, this particular arrangement of them has never been seen on Earth before.

Hemolithin is the latest piece of evidence in the mounting case that life's building blocks began stacking in space, and were delivered to Earth (and possibly other planets) through impacts by space rocks. Plenty of individual amino acids - the building blocks that make up proteins - have been found in meteorites and comets in the past. Amino acid precursors, sugars, organic materials and certain-shaped molecules, all vital for life, have been detected in space or meteorites, too.

Cloud Lightning

Volcanic lightning and what we can learn from the 2018 Anak Krakatau eruption

A phreatomagmatic eruption occurs when water comes into direct contact with magma
The 2018 eruption of Anak Krakatau in Indonesia was remarkable in many ways.

It will be remembered, obviously, for the sudden flank collapse that triggered the tsunami which killed over 400 people on the nearby coastlines of Sumatra and Java.

But the event also has been the source of many scientific insights that could inform future hazard assessments.

And a new possibility is the potential for the frequency of lightning seen at an eruption to give a simple guide to the height of a volcano's towering plume.

It's information that could be of interest to airlines trying to find safe routes for their planes.

Comment: Could it be that as the plume rises higher as well what it's composed of increases the potential for a discharge event between the ground and the atmosphere?

Some clues as to what may be happening may be found in the following extract from Pierre Lescaudron's book Earth Changes and the Human-Cosmic Connection:
Lightning and hurricanes seem to be similar charge rebalancing processes. Lightning mostly occurs above continents and is far less frequent above oceans.1 This may be due to the difference between ground conductivity and sea conductivity. When electrons start flowing upwards from the ocean, the high conductivity of salt water2 usually prevents the formation of electron-deficient regions, which is one of the causes of lightning. However, when the upward electron flow occurs above a continent, the poor conductivity of the ground3 enables the formation of electron-deficient pockets that will trigger and receive lightning discharges.

In terms of location, hurricanes are the opposite of lightning bolts: they mostly occur above oceans and usually weaken or die when they reach land. When a massive flow of electrons is pulled up above the ocean, the high conductivity of salt water can provide and conduct free electrons from all adjacent regions, thus offering an almost endless supply of electrons to power the ongoing hurricane. When the hurricane reaches the ground, the electron supply is limited by the poor conductivity of the ground and the hurricane weakens.

[...]

Notice also that the rainfall that usually accompanies hurricanes also participates in the charge re-balancing process.

When a water drop falls to the ground, it can capture electrons from the bottom of the cloud or below it, thus carrying a negative charge to the ground and rebalancing electric potential differences in a manner similar to lightning. From this perspective, lightning and rain are both caused by a strong atmospheric E-field and both lead to a charge rebalancing between the Earth's surface and its atmosphere.

Notice that the atmospheric field has an influence on raindrops formation and size. In the image below,4 a thin water jet was created by a hypodermic needle connected to a water faucet. On the left, no electric field was applied. The jet took the form of a mist made of small droplets. On the right, an electric field was applied to the water jet, triggering the binding of droplets with each other and the subsequent formation of large water drops. This experiment is very similar to what occurs in clouds, where water droplets tend to align along the atmospheric E-field and attract each other, forming heavier and heavier water drops.

Influence of electric field on the size of water drops.
From the above we can see that lightning and hurricanes are very similar electric phenomena. Hurricanes are to sea surface what lightning bolts are to ground surface. They are both caused by upward electron flows and they both rebalance electric charges by returning electrons to the ground: rainfall in the case of hurricanes, lightning in the case of electrical storms.

Before closing this chapter, a few further comments about atmospheric dust are necessary: as we've seen previously, atmospheric dust plays a major role in storm dynamics. On a physical level it acts as a nucleus for the formation of condensed water droplets (clouds). On an electrical level it holds electric charges that can trigger lightning.

Atmospheric dust also seems able to modulate cloud elevation. According to mainstream science, atmospheric dust and water droplets stay in suspension in the atmosphere because of their very small size, exhibiting low weight and comparatively large drag.5 However, some observations don't fit the gravity-drag model and, in some cases, dust clouds settle much slower than predicted:
Interestingly, it appears that some hitherto unknown atmospheric process counteracts gravitational settling of larger atmospheric dust particles (Maring et al., 2003), as models of long-range dust transport often underestimate the larger particle fraction (Colarco et al., 2003, Ginoux et al., 2001), and dust samples collected after fallout events show that large numbers of 'giant' dust particles (larger than 62.5 micrometers) can be carried thousands of kilometers from their source (Middleton et al., 2001).67
If you remember the Millikan experiment8, a droplet charged with only one electron can counteract gravity and literally levitate when exposed to a vertical electric field. For this to happen, the vertical electric field has to be 32,100 v/m.9 Although the atmospheric electric field is normally about 100 v/m at ground level,10 atmospheric dust or atmospheric droplets, because they reduce conductivity, can drastically increase this value. Electric fields of 2,000 v/m have been measured under dust storms,11 up to 20,000 v/m has been observed under thunderstorms12 and up to 200,000 v/m within thunderstorms.13 In addition, unlike the Millikan experiment, some particles can carry more than one electron charge.

This means that the atmospheric electric field can play a role in the fall speed, location, movement and elevation of clouds whether they are made of dust or droplets (or both). It can cause the particles to 'levitate' or literally rise up in the air.

SpaceX's Starship SN1 prototype blows up during pressure test on its Texas pad

spacex explosion
A prototype for SpaceX's Starship super-rocket was destroyed tonight during a pressure test on its pad at the company's South Texas facility.
  • Streaming video from Boca Chica showed the silo-shaped tank assembly for the prototype known as Starship SN1 wreathed in light and vapor during the test, which was conducted with inert liquid nitrogen. At about 10 p.m. CT (8 p.m. PT), the tank popped. The structure imploded as it flew into the air, then fell to the ground.
  • Initial reports suggested that the tank suffered a structural failure during pressurization. Information about potential injuries or the extent of damage wasn't immediately available, but we've reached out to SpaceX and will update this item with anything we hear.
  • This prototype was designed only for initial rounds of tests. SpaceX plans to use future Starship prototypes for more ambitious tests that would build up to orbital flights. "Not much to worry about here," Next Spaceflight's Michael Baylor tweeted. "Test, fail, fix, test, fail, fix is SpaceX's game. They will learn from it and get it right."

Pioneering Australian technology holds promise of unlimited, clean and safe energy

Technology developed by a UNSW Sydney Emeritus Professor has secured patents for its ground-breaking approach to energy generation.

Technology developed by UNSW Sydney Emeritus Professor Heinrich Hora, has been granted patents for its laser-driven technique for creating fusion energy. Unlike earlier methods, the technique is completely safe as it does not rely on radioactive fuel and leaves no toxic radioactive waste.

HB11 Energy secured its intellectual property rights in Japan last week, following recent grants in China and the USA. Professor Hora said HB11 Energy's concept differs radically from other experimental fusion projects.

Comment: Popular Mechanics adds:
The laser itself is a landmark invention as well — without it, Hora could likely not have created a working idea and patented it after those four decades of research. In 2018, three scientists split the Nobel Prize in Physics for the decades-old chirped pulse laser, including the first woman recipient since Marie Curie.

From Donna Strickland's 1988 thesis on the idea of chirped pulse amplification, the chirped pulse laser has revolutionized all the things we think of as laser-powered today, like medical treatments and ultrafast laser image captures of atoms in motion.

Hora's design seeks to not just compete with, but replace entirely the extremely high-temperature current technologies to achieve fusion. These include fussy and volatile designs like the tokamak or stellarator, which can take months to get up to functionality and still spin out of working order in a matter of microseconds.

Scientists finally confirm a 50-year-old mechanical theory

An experiment by EPFL researchers has confirmed a theory that has been used in mechanics for over half a century — despite never having been fully validated. The team could now use the theory in bolder and more innovative ways in their quest to develop ever better energy systems.

Some theories are widely used even though they have never been experimentally validated. One example is the so-called narrow groove theory, or NGT, which explains how air-lubricated bearings work in mechanical systems.

The theory was proposed in 1965 but, until recently, it had only been tested partially or indirectly. Researchers at EPFL's Laboratory for Applied Mechanical Design (LAMD), based at Microcity in Neuchâtel, have now closed a gap that has persisted in the scientific literature for over 50 years. The team has published its findings in the journal Mechanical Systems and Signal Processing.

How plants have been using humans

Wild Barley

We think we're so clever, but perhaps we underestimate plants.

Edible flora have long evolved ways to move seeds away from their parents to survive and thrive - and humans are just another part of their grand plan, argues Robert Spengler from the Max Planck Institute in Germany.

"Note that if the apple does not fall far from the tree, then the apple seedlings will be overshadowed by the parent tree and not survive," he says.

"Therefore, the apple tree put extensive amounts of energy into producing high-sugar fruits in order to entice animals to spread the seeds."

This included the earliest hominids, long before humans started consciously domesticating plants through breeding, Spengler writes in the journal Trends in Plant Science.

A largely theoretical paper, it was inspired by early scholars of evolution such as Darwin and Humboldt - and many of his ideas came to fruition while sitting across from the Schiller Garden House in Jena, where Humboldt famously spend his summers debating similar concepts before conceiving of the cosmos.

"I think the domestication of plants and animals is one of the most important factors in the demographic shifts and cultural changes that have led humanity into the modern world," he says.

"Therefore, a solid understanding of how this process occurred is essential when studying humanity."

The manuscript draws from paleontological data to highlight parallels between the evolution of seed-dispersal traits in the wild and domestication traits in the fields of early farmers who started intentionally breeding them.

Physicists accidentally discover new way to manipulate electric charge, promising monumental changes in technology

Physicists discover new state of matter

University Distinguished Professor of physics Arun Bansil (left) and associate professor of physics Swastik Kar accidentally discovered a new way to manipulate electronic charge.
American physicists believe that they have discovered a strange state of matter entirely new to science - and they did it all completely by accident.

Famously, many of the greatest scientific discoveries have been accidental. Alexander Fleming let bread go moldy and discovered penicillin. Archimedes splashing about in the bath stumbled upon how to measure the volume of a solid.

It's perhaps an indictment of the modern world's overly-regimented and bureaucratic scientific community that such unintentional breakthroughs never seem to happen anymore. Western university-industrial complexes are burdened with never-ending paperwork, and huge resources devoted to ethical and health and safety requirements. These modern innovations have their benefits, of course, but they do have a major downside, in that they completely smother the more spontaneous side of the scientific method.

But now, a team of scientists at Northeastern University in Boston, Massachusetts, have made an exciting and accidental discovery in the often-overlooked field of materials science. This team has previously made several leaps forward in the world of materials science by stacking ultra-thin 2D layers on top of each other to form new structures. These sheets are only a couple of atoms thick - so thin, in fact, that the electrons within them are restricted to movement in just two dimensions (hence their name '2D materials').

Asteroid invasion: Since three years ago, Earth has had an additional moon! - UPDATE

New Mini-Moon seen orbiting around Earth on February 15, 2020

New Mini-Moon seen orbiting around Earth on February 15, 2020.
In the skies above Earth, astronomers with the Catalina Sky Survey have spotted what might be a new friend: an asteroid temporarily captured by our planet's gravity, what we call a minimoon.


Comment: Perhaps not temporarily! We may be watching history in the making.


It's named 2020 CD3, a small chunk of likely carbonaceous rock between 1.9 and 3.5 metres (6.2 and 11.5 feet) in diameter. And here's the kicker - the rock's trajectory indicates it's been in orbit for around three years already.

The near-Earth neighbourhood is a relatively busy place, with boatloads of asteroids zipping past. The precise numbers, however, are unclear; estimates put the number at millions, but as of February 25, the number discovered was only 22,211.


Comment: Indeed, and it's an increasingly busy place.


That's because asteroids are really small, we don't know where they are (so we don't know where to look), and they typically don't give off a lot of light, even when they're reflecting sunlight.


Comment: Some of them are small, but 'small' is highly relative in outer space.



Comment: "Yay, let's PLAY with it!"

Er, how about we wake up and smell the pooh hitting the fan?

We've long suspected that some (or most) of the 'slow-moving meteors' burning up in the atmosphere of late are in fact asteroids that had been previously captured by Earth's gravity.

The same phenomenon is apparently occurring with respect to other planets in our solar system, whose numbers of 'moons' grow by the year. Those new 'moons' are typically accounted for by 'better observation technology', but clearly the actual numbers of 'moons' are growing...

UPDATE February 28: RT reports that astronomers at the Gemini Observatory in Hawaii have released pictures of 2020 CD3. The image is actually a combination of three separate images using three different filters to capture the new moon. Lead astronomer Grigori Fedorets says he expects to find 'a population of these objects once the Rubin Observatory is operational'..and they may indeed!
