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 / 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 / The far side of the moon provides clues to a past magnetic field

Unlike Earth, the moon no longer has a core-generated magnetic field. On our planet, the movement of liquid iron in the outer core generates a global magnetic field. This so-called geodynamo works on a similar principle to ...

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 / Kibble with microbial proteins appeals to cats and dogs in new study

In a new study, cats and dogs showed a short-term preference for kibble containing some protein derived from microorganisms over kibble containing only standard animal-derived protein. Ally Motta de Matos and A.L.B. Cruz ...

Phys.org / Roaming black holes may tell the hidden history of galaxies

If you want to understand the origins of black holes, Yale astronomers say, you need to look beyond the centers of galaxies and start searching in the nooks and crannies. That's where you'll find the "wanderers"—black holes ...

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 / 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 / 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 ...

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 / Soil heterogeneity helps bacteria find nutrients

Microorganisms regulate key processes in soils and aquifers, including nutrient cycling, carbon turnover and contaminant degradation. Many bacteria use chemotaxis, the ability to sense and swim toward chemical signals, to ...
