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 / Structural study explains how cells stabilize protective membrane pockets
Our cells' membranes have many functions. They not only provide mechanical protection but also precisely control which substances enter or leave cells. If they fail to perform these tasks, disease can result. Their structure ...
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 / 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 / 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 ...
Phys.org / Evolutionary home advantage: Field experiment reveals adaptation to be surprisingly local
A research team from the University of Bern has shown in a large-scale field experiment that populations of the same fish species can be much more fine-tuned to their local environments than previously thought. Habitats that ...
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 / 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 / Pollinators keep a later calendar in human-modified landscapes, study finds
Human development may be changing more than where pollinators live—it may also be changing when they are active. University of Florida researchers at the Institute of Food and Agricultural Sciences (UF/IFAS) have found that ...
Phys.org / Mosquito 'toilet' detects West Nile and first Hedwig-like virus found in the Americas
When public health researchers want to know whether diseases such as COVID-19 or polio are circulating in a community, they can look for genetic evidence in wastewater.
Phys.org / Why do spruce take decades to reproduce? A genetic study offers some clues
New techniques have enabled researchers in Sweden to begin decoding how one of Northern Europe's most important coniferous tree species switches from growing branches to producing cones—their seed-bearing reproductive organs.
Phys.org / Improved climate forecasts alone won't protect Africa's poorest farmers
As Africa prepares for the arrival of a powerful El Niño weather event, an international team of researchers led by the University of Sydney and Imperial College London has found that access to improved forecasts alone will ...
