Phys.org / New solar system models show Earth is no fluke
Over the past three decades, computer models of planetary system formation have gone from fairly crude representations to sophisticated simulations using thousands of different starting points.
Phys.org / Setting limits on phase transitions in the dark energy era
The universe is known to be expanding at an accelerating rate. Physicists typically attribute this acceleration to dark energy, a mysterious component of the universe that exerts negative pressure, causing space to expand ...
Phys.org / LHC collisions reveal oxygen and neon's shifting nuclear geometry
Many people are aware that the Large Hadron Collider (LHC) at CERN smashes tiny subatomic particles together at nearly the speed of light to test foundational laws of physics and discover new fundamental particles, but some ...
Phys.org / A little Big Bang: Bowling-pin-shaped nuclei shed new light on the universe's first moments
What happened in the first moments of the universe—before the building blocks of life and the world we know today came into existence? Physicists at the CERN research facility in Switzerland are trying to answer this question ...
Medical Xpress / Heart capillaries may build natural bypasses for blood flow after heart attacks
The heart powers a busy highway of arteries and vessels, providing a constant to-and-fro passage for blood. During a heart attack, this passage becomes blocked, usually when a blood clot forms on plaque in a coronary artery ...
Phys.org / The little red dots of our cosmos might hide something big
Little red dots may reside in small, dense galaxies with total masses equivalent to around 1 billion times that of the sun, according to research published in Nature Astronomy.
Phys.org / Volcanic eruptions and warming climate disrupt long-standing link between Indian and Pacific oceans
A new study that combines paleoclimate data and climate models suggests that large volcanic eruptions can disrupt the relationship between atmospheric circulation patterns over the tropical Indian and Pacific oceans. In addition, ...
Phys.org / Engineered yeasts help turn PET plastic and crop waste into protein-rich cookies
Plastic might be the last ingredient you would ever add to a cookie recipe. But a team of researchers is looking to change that. They've programmed yeasts to turn plastic and agricultural waste into edible proteins and flavoring ...
Phys.org / Egypt's deserts were once home to a diverse shark community
During the Late Cretaceous period, parts of Egypt were covered in water. A new study, published in the journal Cretaceous Research, describes new evidence that this tropical sea was home to a diverse community of sharks. ...
Phys.org / The hidden physics behind the shape of rose thorns
Roses are known for their thorns, the sharp structures that can sting and prickle the skin. Thorns, botanically known as prickles, are thought to discourage animals from feeding on plants and may also help climbing roses ...
Phys.org / More than half of adults in US say they lack basic statistical understanding
From the daily weather forecast to a baseball player's batting average to an individual's risk of developing lung cancer, understanding statistics can help people in the United States navigate their lives, according to Mark ...
Medical Xpress / Cannabis addiction climbs fast while alcohol use disorder slowly declines across the USA
Alcohol is second on the list of the most addictive drugs in America. By altering the brain's chemistry and triggering the release of pleasure-inducing chemicals like dopamine, alcohol can create a strong desire to repeat ...
