Phys.org / Earth shifted among five 'mega-climate' states over 539 million years, with extinctions spiking near transitions
Earth's climate has undergone dramatic changes throughout its history, but new research suggests those changes may not have been as random as previously thought. A study led by an international team of researchers, including ...
Phys.org / The Antarctic's only two flowering plants reveal opposing strategies for surviving long-term warming
A team of Chilean and Spanish researchers has published the results of one of the longest-running in-situ warming experiments in maritime Antarctica in the journal Physiologia Plantarum. The experiment exposed the Antarctic ...
Phys.org / Pigeons' proposed inner-ear compass runs into a noise problem
A pigeon turning its head might seem an unlikely electricity generator. Yet one proposed explanation for the bird's magnetic sense depends on exactly that: Turning through Earth's magnetic field would produce tiny electrical ...
Phys.org / Evolved enzymes build tuberculosis antibiotic ingredient in the desired form, potentially reducing waste
Tuberculosis, or TB, is a contagious bacterial infection that primarily affects the lungs. While curative treatments exist, more than 80% of cases occur in low- and middle-income nations, where drug-resistant strains are ...
Phys.org / Ancient genome function persists despite frequent mutations, centromere study shows
Every time a cell divides, its chromosomes must be distributed correctly between the two daughter cells. Central to this process is the centromere, a specialized region of the chromosome. The centromere serves as the attachment ...
Phys.org / Quantum device simulates matter popping into existence
A research team led by faculty at the Duke Quantum Center (DQC) has observed string-breaking dynamics related to particle-antiparticle formation on a quantum simulator, among the first such observations in quantum physics.
Phys.org / Unevenness of global warming: Regional warming speedups emerge in waves
New research from the University of California, Santa Cruz, in collaboration with other institutions, highlights the fragmented and staggered timing of warming increases across the planet, providing a nuanced perspective ...
Phys.org / Fluorescence timing identifies eight proteins in one cell with a single staining step
An international collaboration led by the University Medical Center Göttingen (UMG), Germany, has developed a labeling method that distinguishes fluorescent labels not by color but by how long it takes a dye to emit fluorescence. ...
Phys.org / Study reveals how biological echo chambers form—and what can break them
Tropical army ants are known to form devastating armadas that march through forests eating other insects and small creatures. As they march, they deposit chemical trails of pheromones that others behind them sense and follow. ...
Phys.org / Zika virus assembles without protein segment long deemed essential
For years, scientists were certain that two factors were involved in the assembly of active, highly infectious Zika viruses in human cells: a specific viral protein in its entirety and a turncoat human enzyme that assured ...
Phys.org / It's the small things: Treating something as even slightly significant affects motivation
When Fan Yang's children came home complaining about a crafting class, they had a particularly strong advocate.
Phys.org / Natural compound from soil bacteria offers new approach to treating drug-resistant tuberculosis
According to the World Health Organization (WHO), more than 10 million people contract tuberculosis (TB) each year. It is one of the deadliest infectious diseases worldwide. Treatment is lengthy and typically involves a combination ...
