Phys.org / Lebanon: 400,000 years of climate and landscape history rediscovered
An international research team led by Dr. Gabriele Russo of the Senckenberg Centre for Human Evolution and Palaeoenvironment at the University of Tübingen has re-examined historical fossil collections from Lebanon using modern ...
Phys.org / 40-year-old prediction of how plastics 'mix' confirmed for the first time
A "mixing" phenomenon between plastic layers that had been predicted only in theory for 40 years has now been experimentally confirmed.
Phys.org / Radiation-tolerant rotifers rebuild broken chromosomes over successive generations
DNA repair mechanisms are essential for maintaining the integrity of our genome. When they malfunction, they can cause disease or contribute to the development of cancer. Nature, however, offers remarkable examples of organisms ...
Phys.org / How the 2024 solar superstorm drained Earth's radiation belt
In May 2024, Earth experienced its most intense geomagnetic storm since the Halloween storms of 2003. This "superstorm" filled night skies in many parts of the world with colorful aurorae, and it disrupted some infrastructure, ...
Phys.org / Series of reactions reveals how complex carbon chemistry can begin in frigid space
Before there was Earth, there was chemistry. In the unimaginable cold, dark clouds where stars and planets are born, carbon molecules assemble into more complex forms—starting a chemical journey that could eventually deliver ...
Phys.org / Physicists zoom into the birth of cosmic rainstorms with new CERN study
Every second, particles zip through your body at nearly the speed of light. They rain down from a storm high in the sky, where cosmic rays, a powerful type of interstellar matter, constantly strike atoms in Earth's atmosphere. ...
Phys.org / A painting signed 'L daVinci': Analysis reveals Renaissance pigments and later alterations
Researchers at Uppsala University have analyzed the color pigments in a historical painting signed "L daVinci." Most of the pigments are consistent with materials used during the Renaissance, while a more recent pigment appears ...
Phys.org / Three DNA loops prove essential for efficient wing tissue regeneration in fruit flies
After an injury, DNA not only changes its activity but also the way it is organized spatially within the cell nucleus. In this process, certain regions of DNA establish new physical contacts through chromatin loops that act ...
Phys.org / Unused natural gas behind NYC's $300 million waste of a potent greenhouse gas
Methane emissions from the New York City metropolitan area are largely driven by natural gas use, according to a new study published today in Atmospheric Chemistry and Physics by researchers at the Lamont-Doherty Earth Observatory, ...
Phys.org / Common wastewater pollutant turns male minnows into poorer parents and fiercer rivals
A team of researchers has found that a common wastewater pollutant turned male fathead minnows into worse fathers and fiercer rivals, revealing ecological impacts that laboratory studies missed.
Phys.org / Snail shells are surprise weather time capsules
Snails carry weather records on their backs that could be used to map prehistoric cyclones, a University of Queensland study has shown. The project led by School of the Environment researchers examined the rings on the shell ...
Phys.org / Peptide position determines whether gold nanoparticles branch or stay spherical
The position of biomineralization peptides within liposomes can influence how gold nanoparticles grow, reports a research team from the Institute of Science Tokyo. Peptides localized at the membrane interface promote branched ...
