Phys.org / Millions of atoms, shifting bonds—new software brings living chemistry into view
Chemical reactions drive life. They ensure that cells obtain energy, proteins perform their functions, and DNA changes under certain conditions. However, many of these processes occur on extremely small scales—so small and ...
Phys.org / Promiscuity and parental behavior in birds are driven by demographics, not the other way around
New research shows that variation in mating behaviors, parental care and differences in ornamentation of the sexes in bird species is driven by demographics rather than vice versa. An international team of researchers from ...
Phys.org / Q&A: Scientists decode the logic behind cells' mysterious protein stockpiles
As far as research subjects go, it's not always easy to find common ground with a single-celled bacterium. Yet the more Paul Wiggins studies his model bacteria, Acinetobacter baylyi, the more he sees surprising commonalities ...
Phys.org / Seeing is believing: Smart probes reveal proteins inside living cells with unprecedented clarity
Fluorescent probes have transformed modern biology by allowing researchers to tag and visualize individual molecules in living cells, tissues, and animals. Using these tools, researchers can watch viruses infect cells in ...
Phys.org / Wildfire-driven deforestation rates in California among highest in world
California has one of the highest rates of wildfire-driven deforestation in the world, and the trend has accelerated over the past three decades, according to a study from the University of California, Davis. The study, published ...
Phys.org / Geoengineering could protect Amazon rainforest from climate change
Geoengineering could protect the Amazon rainforest from climate change, new research shows. Stratospheric aerosol injection (SAI) aims to artificially cool Earth by increasing the reflection of incoming solar radiation, thereby ...
Phys.org / Measuring how stressed rocks 'sigh' before breaking could help predict geohazards
Too much stress can make even a rock crack. But before rocks reach their breaking point, they "sigh" a chemical warning by releasing nuclides, a type of atom defined by the number of neutrons as well as protons in the nucleus. ...
Phys.org / Comparable vitamin B6 levels found between nonalcoholic and conventional beers
Beer is one of the oldest and most consumed beverages on Earth, typically associated with social and celebratory settings. But researchers are curious about what vitamins and minerals are present in the beverage. A study ...
Phys.org / How a faster protein-screening tool could strengthen US rare-earth supply chains
To ensure a robust domestic supply chain in the U.S., Lawrence Livermore National Laboratory (LLNL) scientists are using bacterial proteins to separate the rare-earth elements that are ubiquitous in magnets, batteries, and ...
Phys.org / Turning four into two: How duplicated genomes become diploid again
Genome duplication probably gave biodiversity a decisive evolutionary boost. A Chinese-German research team led by Axel Meyer from the University of Konstanz has now investigated the early phases of the process known as rediploidization. ...
Phys.org / Cheaper sequencing, bigger payoff: New software could bring advanced metagenomics to more labs
Metagenomics relies on the use of software programs called assemblers, which can reconstruct tens of thousands of individual microbial genomes from DNA sequencing of samples such as soil, bodily fluids, or clinical swabs ...
Phys.org / Cosmetics from waste? Microbial discovery unlocks greener route to high-value chemical products
Researchers at University of Toronto's Department of Chemical Engineering & Applied Chemistry have made a key discovery about how certain bacterial strains produce a set of economically valuable chemicals—opening the door ...
