Physicists mash quantum and gravity and find time, but not as we know it
A University of Queensland-led international team of researchers say they have discovered “a new kind of quantum time order”. UQ physicist Dr Magdalena Zych said the discovery arose from an experiment the team designed to bring together elements of the two big - but contradictory - physics theories developed in the past century.

Scientist models exoplanet’s atmosphere
New research using data from NASA's Spitzer Space Telescope has provided a rare glimpse at the surface of a rocky planet outside our solar system. The planet may be similar to Mercury or Earth's moon, with little to no atmosphere. In the search for life beyond our galaxy, many scientists have their eyes turned toward orbs like Earth: rocky planets.

Quantum gravity's tangled time
Quantum gravity’s tangled time
The theories of quantum mechanics and gravity are notorious for being incompatible, despite the efforts of scores of physicists over the past fifty years. However, recently an international team of researchers led by physicists from the University of Vienna, the Austrian Academy of Sciences as well as the University of Queensland (AUS) and the Stevens Institute of Technology (USA) have combined the key elements of the two theories describing the flow of time and discovered that temporal order between events can exhibit genuine quantum features.

Salt deposits on Mars hold clues to sources of ancient water
For centuries, miners have burrowed into the earth in search of salt-laid down in thick layers from ancient oceans long since evaporated. When scientists saw huge deposits of salt on Mars, they immediately wondered whether it meant Mars too once had giant oceans. Yet it's remained unclear what those deposits meant about the Red Planet's climate.

Physicists design an experiment to pin down the origin of the elements
With help from next-generation particle accelerators, the approach may nail down the rate of oxygen production in the universe. Popular Mechanics reporter David Grossman writes that MIT researchers have designed a new experiment to help identify the rate at which oxygen in the universe is produced. Grossman explains that the study could "lead toward better being able to understand if a dying star will take on the form of a black hole or a neutro

A space cocktail of science, bubbles and sounds
A space cocktail of science, bubbles and sounds
The International Space Station was again the stage for novel European science and routine operations during the first half of August. Plenty of action in the form of bubbles and sounds added to the mix in the run-up to a spacewalk and the comings and goings of visiting vehicles. ESA astronaut Luca Parmitano installed the Multiscale Boiling experiment , known affectionately as Rubi, in its new home in Europe's Columbus laboratory.

Lab-based dark energy experiment narrows search options for elusive force
An experiment to test a popular theory of dark energy has found no evidence of new forces, placing strong constraints on related theories. Dark energy is the name given to an unknown force that is causing the universe to expand at an accelerating rate. It is very exciting to be able to discover something about the evolution of the universe using a table-top experiment in a London basement.

Global team of scientists finish assembling next-generation dark matter detector
Global team of scientists finish assembling next-generation dark matter detector
The key component of the LUX-ZEPLIN experiment is ready to be sealed and lowered nearly 1.5 km underground, where it will search for dark matter. Dark matter is a mysterious form of matter thought to make up around 85% of the mass of the universe. However, because it is predicted to interact only very weakly with ordinary matter, it has so far not been detected.

Two weeks of science and Beyond
Two weeks of science and Beyond
Over two weeks have flown by since ESA astronaut Luca Parmitano was launched to the International Space Station for his second six-month stay in orbit. His arrival, alongside NASA astronaut Andrew Morgan and Roscosmos Soyuz commander Alexander Skvortsov, boosted the Station's population to six and the crew has been busy ever since - performing a wide range of science in space.

Washed up: Sargassum blankets beaches
Washed up: Sargassum blankets beaches
Over the last month, massive quantities of the Sargassum seaweed have been washing up on the shores of Mexico, Florida in the US and some Caribbean islands, creating a serious environmental problem and causing havoc for the tourist industry. ESA has been tracking this slimy infestation from space. Sargassum is a large brown algae, first spotted by Columbus during his voyage to the Americas.

New exoplanet is smallest to be precisely measured
Earthlings have long daydreamed about faraway planets, but only recently have scientists been able to identify thousands of new exoplanets-and to learn more and more about what they look like. The latest: a new exoplanet discovered by NASA's Kepler spacecraft in the constellation of Cancer. Thanks to good timing and the planet's odd orbital pattern, scientists with the University of Chicago were able to calculate its mass more precisely than any other planet this small to date.

TESS discovers three new planets nearby, including temperate "sub-Neptune"
Planetary system orbiting an unusually quiet star is ideal for future habitability searches. Cecelia Smith-Schoenwalder writes for US News & World Report about the planet hunting satellite TESS, which has recently discovered three new exoplanets. "The pace and productivity of TESS in its first year of operations has far exceeded our most optimistic hopes for the mission," said Senior Research Scientist George Ricker, TESS's principal investigator.

Scientists Weigh the Balance of Matter in Galaxy Clusters
A method of weighing the quantities of matter in galaxy clusters - the largest objects in our universe - has shown a balance between the amounts of hot gas, stars and other materials. The results are the first to use observational data to measure this balance, which was theorized 20 years ago, and will yield fresh insight into the relationship between ordinary matter that emits light and dark matter, and about how our universe is expanding.

"It was the greatest adventure of the 1960s"
Professor Schreiber, how big an impression did the Moon landing make on you when you were young? It wasn't just the Moon landing as such. What amazed me most were the steps that led up to it. It was a huge technical challenge. For example the question: How do I accelerate a rocket to reach the Moon? Back then, the technical possibilities were still quite limited.

50 years later, UChicago scientists continue to decode moon’s mysteries
Fifty years ago, NASA astronauts stepped off Apollo 11 and delivered what instantly became the most precious rock on Earth: nearly 50 pounds of dust and rock fragments from the surface of the moon. Suddenly, the wildest dreams of geoscientists had come true, as tiny pieces of the first rocks collected on another celestial body made their way to labs across the U.S. for analysis.
