Advanced data shed light on gravitational basins of attraction that shape the movement of galaxies
A new study has mapped out the gravitational basins of attraction in the local universe, offering fresh insights into the large-scale cosmic structures that shape the movement of galaxies. The study has been published in Nature Astronomy......»»
New method enables noninvasive plant magnetic resonance imaging
The "omics" technologies—genomics, transcriptomics, proteomics, and metabolomics—are at the forefront of discovery in modern plant science and systems biology. In contrast to the rather static genome, however, the metabolome and the products meas.....»»
Scientists create model of holographic dark energy that is no longer unstable
In 1998, scientists discovered that our universe expands with acceleration, and in order to explain this effect, the concept of dark matter was introduced. This is a special type of energy that fills up all of existing space-time but is impossible to.....»»
Why the gender gap in physics has been stable for more than a century
As a physicist and data scientist with a keen interest in gender inequality, Fariba Karimi was amazed to discover that the gender gap in physics has remained almost unchanged since 1900. As the citation and coauthorship networks in physics expand, wo.....»»
Injecting manure into growing cover crops can cut pollution, support corn crops
Nitrogen in the soil, where plants can readily utilize it, benefits crop growth and health. However, nitrogen leaving the soil—whether through leaching into the groundwater table, flowing with surface runoff into streams or escaping into the air as.....»»

Better together: Gut microbiome communities found to have enhanced resilience to drugs
Many human medications can directly inhibit the growth and alter the function of the bacteria that constitute our gut microbiome. EMBL Heidelberg researchers have now discovered that this effect is reduced when bacteria form communities......»»
Graphene spike mat uses ordinary fridge magnet tech to fight antibiotic resistance
With strong bactericidal properties, graphene has the potential to become a game changer in the fight against antibiotic-resistant bacteria. So far there have been no efficient ways to control these properties—and thus no way to make use of graphen.....»»
Graphene at 20: Still no sign of the promised space elevator, but the material is quietly changing the world
Twenty years ago this October, two physicists at the University of Manchester, Andre Geim and Konstantin Novoselov, published a groundbreaking paper on the "electric field effect in atomically thin carbon films." Their work described the extraordinar.....»»
Proof-of-concept study uses X-rays to target mock-up asteroids in a vacuum
An X-ray pulse may be able to vaporize the surface of an asteroid and change its trajectory, according to a proof-of-concept paper published in Nature Physics. A laboratory experiment that mimics the deflection of an asteroid model using this techniq.....»»
New physics needed? Experts suggest possibility of updating fundamental physics concepts
An unexpected finding about how our universe formed is again raising the question: do we need new physics? The answer could fundamentally change what physics students are taught in classes around the world......»»
High-resolution images of the sun show how flares impact the solar atmosphere
Solar flares are a fascinating thing and have a profound effect on what astronomers refer to as "space weather." These events vary with the sun's 11-year solar cycle, releasing immense amounts of radiation across the electromagnetic spectrum (from ex.....»»
Even the heaviest particles experience the usual quantum weirdness, new experiment shows
One of the most surprising predictions of physics is entanglement, a phenomenon where objects can be some distance apart but still linked together. The best-known examples of entanglement involve tiny chunks of light (photons), and low energies......»»
