Phys.org / Tomb more than 1,000 years old found in Panama
Archaeologists have discovered a tomb more than a thousand years old in Panama containing human remains alongside gold and ceramic artifacts, the lead researcher told AFP on Friday.
Phys.org / Study reveals hidden climate impact of digital industries
Digital technologies are widely viewed as drivers of efficiency, growth, and innovation. However, their contribution to climate change is significantly greater than previously understood. A new study published in the journal ...
Phys.org / Quantum entanglement pushes optical clocks to new precision
By replacing single atoms with an entangled pair of ions, physicists in Germany have demonstrated unprecedented stability in an optical clock. Publishing their results in Physical Review Letters, a team led by Kai Dietze ...
Medical Xpress / Historical trends in U.S. heroin use: Initiation after 2000 differs from earlier patterns
The production, distribution, and consumption of illegal opioids create problems for public health and safety in many countries. Overdose rates are particularly high in Canada and the United States, which experienced three ...
Phys.org / Ribosome could have emerged from ancient antagonism between parasites and proto-cells
Ribosomes are the components of cells that read RNA and build proteins. Without the ribosome, the chemistry of life would still be catalyzed by raw RNA. And yet the origin of the ribosome remains a mystery. In a Perspective ...
Phys.org / Scientists isolate climatic fingerprints of wildfires and volcanic eruptions
Volcanoes and wildfires can inject millions of tons of gases and aerosol particles into the air, affecting temperatures on a global scale. But picking out the specific impact of individual events against a background of many ...
Medical Xpress / Kenya-Uganda trial reduces HIV incidence by 70% in rural populations
By pairing digital tools with tailored HIV services delivered by community health workers and clinicians, a study has reduced new HIV cases by 70% in rural Kenya and Uganda. This successful strategic implementation of existing ...
Phys.org / Breadcrumbs offer fossil fuel–free production of everyday goods
The humble breadcrumb could hold the key to cutting out fossil fuels from one of the chemical industry's most widely used reactions, according to a new study. Scientists have found a one-pot microbial formula that uses waste ...
Phys.org / Plant hormone therapy could improve global food security by balancing growth with immunity
Plants have an immune system, like people, and when it is triggered by threats like disease or pests, a plant's defenses are activated. But there's a downside to this protective mechanism: the plant's growth is suppressed ...
Phys.org / A new method reveals hidden rules of gene control
Inside every cell, thousands of molecular signals collide, overlap, and compensate, obscuring the true drivers of gene expression. Scientists have now developed a way to silence that cellular noise, revealing transcription ...
Tech Xplore / A heatshield for 'never-wet' surfaces: Engineers repel even near-boiling water with low-cost, scalable coating
Superhydrophobic surfaces—those famously "never-wet" materials that make water bead up and roll away—have a stubborn weakness: hot water. Once temperatures climb above roughly 40 degrees Celsius, many superhydrophobic ...
Phys.org / How cells manage nitric oxide: Research uncovers dynamic 'gate' that tames powerful signaling molecule
Cornell researchers have uncovered a built-in molecular "gate" that controls the production of the molecule nitric oxide, a crucial signaling molecule throughout biology that in humans helps regulate blood pressure, brain ...
