If humans ever hope to colonize Mars, the settlers will need to manufacture on-planet a huge range of organic compounds, from fuels to drugs, that are too expensive to ship from Earth.
University of California, Berkeley, and Lawrence Berkeley…

High altitude water Cherenkov Observatory tests speed of light
New measurements confirm, to the highest energies yet explored, that the laws of physics hold no matter where you are or how fast you’re moving.
Observations of record-breaking gamma rays prove the robustness of Lorentz Invariance – a piece of…

New explanation for sudden heat collapses in plasmas can help create fusion energy
Scientists seeking to bring the fusion that powers the sun and stars to Earth must deal with sawtooth instabilities — up-and-down swings in the central pressure and temperature of the plasma that fuels fusion reactions, similar to the serrated…

Argonne and CERN weigh in on the origin of heavy elements
A long-held mystery in the field of nuclear physics is why the universe is composed of the specific materials we see around us. In other words, why is it made of “this” stuff and not other stuff?
Specifically of interest are the physical…

Astronaut urine to build moon bases
The modules that the major space agencies plan to erect on the Moon could incorporate an element contributed by the human colonizers themselves: the urea in their pee.
European researchers have found that it could be used as a plasticizer in the…

New technique looks for dark matter traces in dark places
So far, the only direct evidence we have for the existence of dark matter is through gravity-based effects on the matter we can see.
And these gravitational effects are so pronounced that we know it must make up about 85 percent of all matter in…

Holographic cosmological model and thermodynamics on the horizon of the universe
The expansion of the Universe has occupied the minds of astronomers and astrophysicists for decades.
Among the cosmological models that have been suggested over the years, Lambda cold dark matter (LCDM) models are the simplest models that can…

New material developed could help clean energy revolution
Fuel cells and water electrolyzers that are cheap and efficient will form the cornerstone of a hydrogen fuel based economy, which is one of the most promising clean and sustainable alternatives to fossil fuels.
These devices rely on materials…

BU astrophysicist and collaborators reveal a new model of our heliosphere
The heliosphere is a vast region, extending more than twice as far as Pluto. It casts a magnetic “force field” around all the planets, deflecting charged particles that would otherwise muscle into the solar system and even tear through…

Ocean changes almost starved life of oxygen 800 million years ago
Chemical changes in the oceans more than 800 million years ago almost destroyed the oxygen-rich atmosphere that paved the way for complex life on Earth, new research suggests.
Then, as now, the planet had an “oxidizing” atmosphere, driven by…
