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 / 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 / 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 / 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 ...
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 / 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 / Getting photons into shape for reliable quantum communication
The vast majority of modern quantum technologies—from quantum cryptography to the quantum internet to the quantum computer—rely on one essential element: the transmission of photons. Two qubits (two atoms, for example) exchange ...
Phys.org / Cancer-linked protein binds to chromosome in unexpected way, study finds
A new 3D structure of a cancer-linked protein bound to its cellular partner reveals details of how the protein binds to chromosomes and could offer insights for future disease treatments. The protein—BRD4—plays a critical ...
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 / Chocolate's new climate threat: Too much rain
Cocoa farmers in West Africa cannot stop intense downpours from damaging their crops. But they may be able to anticipate the risk and prepare, protecting both their livelihoods and their plants, the source of one of the world's ...
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 / How can countries prevent shocks and disasters from turning into food crises? Analysis points to resilience measures
Floods, wildfires, conflicts, earthquakes, economic shocks, hurricanes or epidemics: These unexpected and often dramatic events affect people's lives and jobs, destroy crops, wipe out livestock and stored food, contaminate ...
