Bacterial cells can 'remember' brief, temporary changes to their bodies and immediate surroundings, a new study has found. And, although these changes are not encoded in the cell's genetics, the cell still passes memories of them to its offspring -- for multiple generations.
Among Viking societies, Norway was much more violent than Denmark
A new study sheds light on how Viking Age societies in Norway and Denmark differed in their experiences with violence and the role social structures played in shaping those patterns.
Prioritizing the unexpected: New brain mechanism uncovered
Researchers have discovered how two brain areas, neocortex and thalamus, work together to detect discrepancies between what animals expect from their environment and actual events. These prediction errors are implemented by selective boosting of unexpected sensory information. These findings enhance our understanding of predictive processing in the brain and could...
Love is blind for male fruit flies who will choose sex over safety
Male fruit flies will become oblivious to physical danger as they become more engaged in courtship and sex.
Rain or shine? How rainfall impacts size of sea turtle hatchlings
An internationally collaborative study delves into how fluctuating rainfall impacts the development of sea turtle hatchlings, revealing that it has a more profound effect than changes in air temperature. Regional weather influences incubation and hatchling development and the impact of rainfall varies between species. For loggerhead turtles, heavier rainfall results...
This new technique for studying cell receptors could have sweeping implications for drug development
Researchers created a tool capable of comprehensively mapping crucial interactions underlying drug efficacy in one superfamily of cell receptors.
Work toward a cleaner way to purify critical metals
Over the past three years, a team of researchers has been pioneering an environmentally friendly method to separate critical rare-earth elements from watery mixtures.
Aoudad, bighorn sheep share respiratory pathogens
A team of researchers has discovered that aoudad -- an animal in the sheep and goat family -- can catch and spread many of the same respiratory pathogens that can impact desert bighorn sheep, a native species in Texas that often shares its habitat with aoudad.
Scientists develop AI-driven method to enhance electron microscopy imaging capabilities of complex biological systems
Electron microscope (EM) has revolutionized our ability to visualize the intricate details inside cells. The advancement to 3D electron microscopy, known as volume EM (vEM), has further expanded this three-dimensional, nanoscale imaging capacity. However, trade-offs between imaging speed, quality, and sample size still limit the achievable imaging area and volume....
Study shows reduced inflammation in residents after adding trees to their neighborhoods
A new project has found that people living in neighborhoods where the number of trees and shrubs was more than doubled showed lower levels of a blood marker of inflammation than those living outside the planted areas. General inflammation is an important risk indicator for heart disease and other chronic...
