Liquid water exists in two different forms, new research reveals. Here, an illustration of the water molecule in front of an X-ray pattern from high-density amorphous ice, created by creating high pressures and low temperatures.
Liquid water comes in two forms — low density and high density, scientists have found.

The findings add to the anomalous properties of this ubiquitous, life-giving liquid, which is like no other on Earth.
"The new remarkable property is that we find that water can exist as two different liquids at low temperatures where ice crystallization is slow," Anders Nilsson, a chemical physicist at Stockholm University in Sweden, said in a statement.


Researchers hunt for clues linking epigenetics and stress

Studies of human populations suggest that our health and longevity could be affected by the diets and experiences of our grandparents. For example, studies of a small community in northern Sweden where detailed historical records were kept found correlations between food availability for one generation and the mortality rate for that generation's grandchildren.

But the exact nature of these effects and how they are transmitted across generations remain unclear. In Susan Strome's lab at UC Santa Cruz, research on a tiny roundworm called C. elegans is helping to solve this puzzle.
"NIH is supporting this basic research in a model organism because it is the only way to crack open the mechanisms behind the correlations seen in human studies. You can't do these kinds of experiments in humans," said Strome, a distinguished professor of molecular, cell, and developmental biology.
Biologists have suspected for years that some kind of epigenetic inheritance occurs at the cellular level. The different kinds of cells in our bodies provide an example. Skin cells and brain cells have different forms and functions, despite having exactly the same DNA.

The most violent type of weather storm on planet Earth is a tornado. Meteorologists tell us that the unstable air in a thunderstorm produces updrafts and downdrafts, which interacts with a wind shear to ultimately create a tornado vortex. But many scientists acknowledge that the exact processes that cause a tornado remain mysterious. In recent Space News episodes, Thunderbolts contributor Andrew Hall has explored the electrical genesis of lightning and other earthly weather phenomena. Today, Hall offers his own thesis on the electrical genesis of tornadoes on Earth.

Andy's original Thunderblog: https://www.thunderbolts.info/wp/2017...

Comment: Study: Tornado outbreaks are increasing - but scientists don't understand why. A coauthor of this paper states "What's pushing this rise in extreme outbreaks is far from obvious in the present state of climate science."

The climate scientists have not considered the importance of atmospheric dust loading and the winning Electric Universe model in their research. Such information and much more, are explained in the book Earth Changes and the Human Cosmic Connection by Pierre Lescaudron and Laura Knight-Jadczyk.
The accumulation of cometary dust in the Earth's atmosphere plays an important role in the increase of tornadoes, cyclones, hurricanes and their associated rainfalls, snowfalls and lightning. To understand this mechanism we must first take into account the electric nature of hurricanes, tornadoes and cyclones, which are actually manifestations of the same electric phenomenon at different scales or levels of power.
Increasing cometary and volcanic dust loading of the atmosphere (one indicator is the intensification of noctilucent clouds we are witnessing) is accentuating electric charge build-up, whereby we can expect to observe more extreme weather and planetary upheaval as well as awesome light shows and other related mysterious phenomena.


Forgetting actually makes you smarter

The inability to remember has long been considered a failure of the brain, but a new study has found that our brains are actively working to forget memories in order to retain the truly important information.

In fact, the study's researchers believe the brain is not designed to keep memories intact, but its actual purpose is to only hold onto valuable information to optimize intelligent decision making overtime.
"It's important that the brain forgets irrelevant details and instead focuses on the stuff that's going to help make decisions in the real world," says Blake Richards, author of the study and associate fellow in the Learning in Machines and Brains program.

A new bioactive nanomaterial, powered by sugar, shows promise at stimulating bone regeneration. While the new method has only been studied in an animal model of spinal fusion, researchers at Northwestern University say it could readily translate to humans.

Samuel I. Stupp, professor of materials science and engineering, chemistry, medicine and biomedical engineering at Northwestern University, said:
"Regenerative medicine can improve quality of life by offering less invasive and more successful approaches to promoting bone growth. Our method is very flexible and could be adapted for the regeneration of other tissues, including muscle, tendons, and cartilage."
In the US, more and more of an aging but active population undergoes spinal fusion to treat pain due to disc degeneration, trauma, and other back problems. Other medical procedures could benefit from the nanomaterial as well, including bone trauma repair, bone cancer treatment, and bone growth for dental implants.


Dogs cloned from ears arrive in Russia for genetic research

Lab-produced dogs cloned from bio material taken from the two best representatives of the Yakutian Laika species have arrived in Russia from South Korea for genetic research. One met its 'original mother' as a Ruptly crew filmed the moment.

The puppies, which were cloned by South Korea's Sooam Biotech Research Foundation, one of the world's leading dog cloning laboratories, arrived in Yakutsk, the capital of Siberia's Yakutia Republic, on Friday. The research was led by Dr. Hwang Woo Suk and his team.


'We made history': NASA launches world's lightest & first 3D-printed satellite, designed by Indian teen

NASA has launched the world's lightest satellite into space, designed by an 18-year-old Indian student. The instrument, which weighs just 64 grams, is also the first satellite to be 3D printed.

The 'KalamSat' satellite, named after India's former President APJ Abdul Kalam, also a nuclear scientist, was launched from NASA's Wallops Flight Facility in Virginia on Thursday.

"Today we made history," the satellite's designer, 18-year-old Rifath Shaarook, told ANI news agency.


Unknown, unseen object signalled by warped Kuiper Belt

A yet to be discovered, unseen "planetary mass object" makes its existence known by ruffling the orbital plane of distant Kuiper Belt objects, according to research by Kat Volk and Renu Malhotra of the UA's Lunar and Planetary Laboratory. The object is pictured on a wide orbit far beyond Pluto in this artist's illustration.
An unknown, unseen "planetary mass object" may lurk in the outer reaches of our solar system, according to new research on the orbits of minor planets to be published in the Astronomical Journal. This object would be different from—and much closer than—the so-called Planet Nine, a planet whose existence yet awaits confirmation.

In the paper, Kat Volk and Renu Malhotra of the University of Arizona's Lunar and Planetary Laboratory, or LPL, present compelling evidence of a yet-to-be- discovered planetary body with a mass somewhere between that of Mars and Earth. The mysterious mass, the authors show, has given away its presence—for now—only by controlling the orbital planes of a population of space rocks known as Kuiper Belt objects, or KBOs, in the icy outskirts of the solar system.

While most KBOs—debris left over from the formation of the solar system—orbit the sun with orbital tilts (inclinations) that average out to what planetary scientists call the invariable plane of the solar system, the most distant of the Kuiper Belt's objects do not. Their average plane, Volk and Malhotra discovered, is tilted away from the invariable plane by about eight degrees. In other words, something unknown is warping the average orbital plane of the outer solar system.

"The most likely explanation for our results is that there is some unseen mass," says Volk, a postdoctoral fellow at LPL and the lead author of the study. "According to our calculations, something as massive as Mars would be needed to cause the warp that we measured."

The Kuiper Belt lies beyond the orbit of Neptune and extends to a few hundred Astronomical Units, or AU, with one AU representing the distance between Earth and the sun. Like its inner solar system cousin, the asteroid belt between Mars and Jupiter, the Kuiper Belt hosts a vast number of minor planets, mostly small icy bodies (the precursors of comets), and a few dwarf planets.


65ft tall and 125 million years old: Scientists unearth fossils of enormous dinosaur

Researchers have uncovered the fossils of one of the largest dinosaurs to ever walk on the Earth - remains which they believe could belong to a previously undiscovered species.

Paleontologists digging near the city of Morella in eastern Spain discovered the remains of a gigantic dinosaur which would have measured a staggering 20-meters (65 ft) from head to tail.

The team unearthed over 80 bones belonging to the same dinosaur, Spanish newspaper El Pais reports. Included in this haul were two femurs, a humerus, other parts of limbs and vertebrae from the tail of a sauropod dinosaur from the Early Cretaceous period.


Experts at Queen's University in Ireland warn Earth is overdue for catastrophic asteroid strike

Experts with Queen's University Belfast (QUB) in Northern Ireland have warned that it's only a matter of time before a large asteroid strikes Earth, causing a natural catastrophe unparalleled in the ruin that it would bring.

Dr. Alan Fitzsimmons, an expert with QUB's Astrophysics Research Center, compared the inevitable destruction to the Tunguska event of 1908, when a meteoroid exploded in orbit above a Siberian forest, raining impactors down on the woods below. The impact, estimated to have been the equivalent of 3 to 5 megatons of TNT (333 to 500 times as much power as the atomic bomb dropped on Hiroshima), flattened 770 square miles of forest. No human casualties were reported, but had the event happened in a densely populated area, the casualties would have likely been in the millions.

Since then, Earth has had its fair share of near misses. In January, an asteroid as big as or larger than the Tunguska impactor came within 110,000 miles of Earth - less than half the distance between the Earth and the moon, a stone's throw by astronomical standards. In August 2027, an asteroid half a mile long is expected to buzz the Earth, and has a tiny chance of striking the planet.
