Research suggests negative emotions at work can help, depending on leaders' empathy

phys.org

During a widespread crisis, negative emotions don't simply go away once the workday begins. Organizational scholars who study how emotions affect employees tend to assume that negative emotions equal negative outcomes. That isn't always…

Adding 1,000 immigrants tied to 142 more health workers, fewer elderly deaths

phys.org

New research finds the addition of a thousand new immigrants in a metropolitan area reduces elderly mortality by about 10 deaths than would be typical. Why? Because among the newcomers are foreign-born health care workers who are arriving…

Drought spurs rise in antibiotic-resistant soil microbes

phys.org

A new Caltech study indicates that drought increases the abundances of antibiotic-resistant microorganisms in soils, which directly correlates with an increase in antibiotic-resistant infections in hospitals. In other words, regions…

Male bats sing in the rotor-swept zone of wind turbines, potentially raising collision risk

phys.org

A research team led by the Museum für Naturkunde presents the first evidence that several bat species produce courtship songs in the immediate rotor-swept zone of wind turbines while circling around the nacelle. Data from over 80,000 audio…

Biosensor detects early fungal outbreaks, advances plant biotechnology

phys.org

A new biosensor developed at the Department of Energy's Oak Ridge National Laboratory detects the emerging presence of fungus on plants at the molecular level, paving the way for next-generation crop protection and the development of…

Shift in key cosmic inflation measurement could be a statistical artifact

phys.org

For the last few decades, researchers have been studying what the universe looked like in its first seconds. It is generally accepted that the universe expanded exponentially in the first fraction of a second after the Big Bang.…

Euthanasia rates for stray dogs triple as more animals enter UK shelters

phys.org

A stark rise in the number of stray dogs being euthanized across the UK and the Republic of Ireland, with rates more than tripling over a three-year period, are revealed in a new collaborative study. The research is published in Animals.

Gran Dolina site at Atapuerca reveals almost exclusive use of local chert 400,000 years ago

phys.org

A paper published in the journal Quaternary International reveals a distinctive technological behavior at level TD10.2-BB of Gran Dolina (Atapuerca, Burgos), characterized by the almost exclusive use of local chert and linked to one of the…

New findings on the first steps in protein synthesis

phys.org

In the earliest phase of creating human proteins, the protein complex NAC performs an essential task by starting the first steps toward folding proteins into their correct three-dimensional structures. An international research team led by…

Single-cell sequencing reveals unexpected protist diversity

phys.org

Researchers from the Earlham Institute, in collaboration with the Department of Biology at the University of Oxford, have discovered three previously unrecognized lineages of the protist Bodo, each with its own bacterial endosymbiont (a…

Why cultivating drought-resistant plants disappoints: Soil physics may be the real bottleneck

phys.org

Plants need water, light, and air to thrive. But when they transport water from the soil up to their leaves, they defy gravity. Scientists describe this astonishing phenomenon as "negative water potential," a form of negative tension that…

A sudden surge in luminosity: Stacked dyes hint at brighter organic semiconductors

phys.org

In nature, a certain size is often a prerequisite for biomolecules to perform their specific functions. For example, for proteins or DNA to fulfill their vital tasks, they must be folded in a precise manner—and this requires a certain…

Chaos as a matter of direction: Researchers build layered material where order and disorder coexist

phys.org

Some materials behave unexpectedly. They crack differently than expected, or react in ways that are hard to explain. The answer often lies in their atomic structure. Is it neatly arranged, as in a crystal, or disordered, as in glass?…

From slices to whole bodies: How 3D cell atlases could reshape pathology research

phys.org

In conventional pathology and physiology research, two-dimensional (2D) analysis—observing thinly sliced tissue sections—has been mainstream, making it difficult to comprehensively understand the distribution of cells across entire organs…
