Scientists Discovered A New State Of Water, Proving How Much We Still Don’t Know

It has a mysterious fourth state that we’d never seen before

The growing list of corrections science textbook writers will have to make could make our third grade curriculum practically unrecognizable. In addition to nixing Pluto from the classic lineup of planets in our solar system, teachers may have to add a second liquid state to the traditional phases of water—aka solid ice, liquid, and gas. Researchers presented this fourth state recently in a paper for the International Journal of Nanotechnology. The writers found that, when heated between 122 to 140 degrees Fahrenheit (or 50 and 60 degrees Celsius), water’s physical properties undergo a change that cannot be so easily classified.


But to understand why this is relevant, let’s take a step back. States of matter, as you probably learned in grade school, have to do with the way atoms and molecules arrange themselves depending on the amount of energy present, or lack thereof. Put simply, the higher the temperature, the higher the energy and the more disorganized the atoms become. Less energy is present at cooler temperatures, which is why water molecules are more orderly in a solid ice stage than in vapor. You’ve probably seen some version of this explaining it visually:

As detailed in this recent paper, researchers found a surprising glitch in water’s physical properties once it reached 122 degrees Fahrenheit, a structural change that appeared to be an extra, less atomically organized liquid phase. Independent researchers will need to conduct follow-up experiments to prove this second liquid state, and should they succeed, the implications could be wide-ranging. Water plays a crucial role in the development of most organisms, which means understanding how it operates could help us better understand our own biological systems on a fundamental level. What this finding proves more than anything, though, is how quickly and easily basic concepts can change. Water’s fourth state may not feel as groundbreaking as discovering the world revolves around the sun, but time will tell how much it may change our understanding of the world in big and small ways.

Young leaders from around the world are gathering at the United Nations Headquarters in New York Saturday to address arguably the most urgent issue of our time. The Youth Climate Summit comes on the heels of an international strike spearheaded by Greta Thunberg, the 16-year-old climate activist from Sweden, who arrived in New York via emissions-free sailboat earlier this month.

Translated from Swedish, "berg" means "mountain," so it may feel fated that a young woman with Viking blood in her veins and summit in her name would be at the helm. But let's go out on a limb and presume Thunberg, in keeping with most activists, would chafe at the notion of pre-ordained "destiny," and rightly so. Destiny is passive — it happens to you. It's also egomaniacal. Change, on the other hand, is active; you have to fight. And it is humble. "We need to get angry and understand what is at stake," Thunberg declared. "And then we need to transform that anger into action."

This new generation of activists' most pernicious enemy is denial. The people in charge — complacent politicians and corporation heads who grossly benefit from maintaining the status quo — are buffered from real-life consequences of climate change. But millions of people don't share that privilege. For them, climate change isn't an abstract concept, but a daily state of emergency, whether it comes in the form of "prolonged drought in sub-Saharan Africa…devastating tropical storms sweeping across Southeast Asia, the Caribbean and the Pacific…[or] heatwaves and wildfires," as Amnesty International reportsare all too real problems people are facing on a regular basis.

Millions of people in over 150 countries across the globe marched for lawmakers and corporations to take action to help stop climate change on Friday, September 20.

The Climate Strikes were organized by children around the world as an extension of the of the "Fridays for Future" campaign. Students have been walking out of classrooms on Fridays to speak out about political inaction surrounding the climate crisis.

"We need to act right now to stop burning fossil fuels and ensure a rapid energy revolution with equity, reparations and climate justice at its heart," organizers say.

There's no doubt the visual images from the marches send a powerful message to those on the ground but especially those watching from around the world. GOOD's own Gabriel Reilich was on the scene for the largest of the Climate Strikes. Here are 18 of the best signs from the Climate Strike march in New York City.

September 20th marks the beginning of a pivotal push for the future of our planet. The Global Climate Strike will set the stage for the United Nations Climate Action Summit, where more than 60 nations are expected to build upon their commitment to 2015's Paris Agreement for combating climate change.

Millions of people are expected to take part in an estimated 4,000 events across 130 countries.

When the iPhone 11 debuted on September 10, it was met with less enthusiasm than the usual iPhone release. A lot of techies are holding off purchasing the latest gadget until Apple releases a phone with 5G technology.

Major US phone carriers have yet to build out the infrastructure necessary to provide a consistent 5G experience, so Apple didn't feel it necessary to integrate the technology into its latest iPhone.

A dramatic new feature on the iPhone 11 Pro is its three camera lenses. The three lenses give users the the original wide, plus ultrawide and telephoto options.

We often dismiss our dreams as nonsensical dispatches from the mind while we're deep asleep. But recent research proves that our dreams can definitely affect our waking lives.

People often dream about their significant others and studies show it actually affects how we behave towads them the next day.

"A lot of people don't pay attention to their dreams and are unaware of the impact they have on their state of mind," said Dylan Selterman, psychology lecturer at the University of Maryland, says according to The Huffington Post. "Now we have evidence that there is this association."
