Phys.org / A chemical failsafe can save crops from disease without crushing growth

Salicylic acid, the active molecule in aspirin and some acne medications, is a hormone in plants that is essential for immunity, but it's a double-edged sword: Too much can cause autoimmunity and stunt growth. In a study ...

Phys.org / Water and 13 hallmarks of complexity trace path from molecules to life

Many properties of molecules cannot be predicted from the properties of the atoms they consist of. These properties only emerge when they are combined—a phenomenon known in science as "emergence." A publication by Goethe ...

Phys.org / It's complicated: New research reveals more about the social networks of baboons and African monkeys

Like people, nonhuman primates live in groups that vary in size and shape depending on the species. Some primate groups are small and simple; others are large and more layered. Over the decades, primatologists have observed ...

Phys.org / Super transformer aims to bring order to biology's data under one AI model

Modern biology is awash in data. Scientists can sequence DNA, track gene activity cell-by-cell, map proteins in space, and image tissues at microscopic resolution. However, it is a struggle to put all that information together ...

Phys.org / Elastic rules may explain why nematic crystals look ordered and disordered at once

Electronic nematicity is a phase of some crystalline solids in which electrons' collective properties, such as charge or spin densities, organize themselves into ordered patterns, lowering the crystal's rotational symmetry. ...

Phys.org / Understanding how lasers can rapidly magnetize fusion plasmas

The mechanism that can cause a rapidly expanding plasma—the superhot state of matter harnessed in fusion energy systems—to spontaneously generate its own magnetic fields was identified through a new set of simulations. This ...

Phys.org / Packed together, they melt differently: What happens when one iceberg enters another's icy wake

Earth's ice is melting. As icebergs break away from glaciers and melt away, the fresh meltwater mixes into its saltwater surroundings. However, icebergs do not exist in isolation. In Greenland, for example, jammed collections ...
