Phys.org / Variations in virus tails may help predict which phages kill more bacterial strains
Bacteriophages—or phages, for short—are viruses that kill bacteria, and scientists have been studying them for decades as a possible solution to antibiotic-resistant infections. But phages are notoriously picky eaters—a phage ...
Phys.org / Uncovering gravity's impact on the human genome
The Human Genome Project was launched in 1990, preceded by decades of breakthroughs in genetics. It eventually gave us a sequence of the human genome. Yet, while the physical rules behind the genome's organization remain ...
Phys.org / Can this biotech innovation halt the destructive march of a cereal killer?
A UK-led research collaboration has taken a significant step in the global effort to protect cereal crops from the devastating blast fungus. Researchers at the John Innes Centre explored a recently discovered class of plant ...
Phys.org / Snapshots reveal key molecular machine in tropical parasites at near-atomic resolution
A study conducted by the University of Liège and Rockefeller University reveals, with near-atomic precision, the three-dimensional structure and function of a gigantic molecular machine essential to the survival of trypanosomatid ...
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 / 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 ...
Phys.org / Starch-based sensor changes color to indicate moisture in food packaging
Brazilian researchers have developed a biodegradable, starch-based sensor that changes color when moisture enters food packaging. With the addition of cobalt chloride, the sensor changes from blue to pink as moisture levels ...
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 / Brain organoids uncover how primates develop different brain shapes
Most primate species have relatively large brains with surfaces marked by pronounced bulges and furrows. This is not the case with common marmosets (Callithrix jacchus). The brains of these small monkeys are smooth and virtually ...
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 / 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 / Past emissions from top polluters will keep the planet warmer for decades to come
If someone leaves the faucet running in your bathroom and the house floods, it's easy to assign responsibility for the damage. But for other disasters—bigger, more complicated and costlier ones—the link between cause and ...
