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 symbiotic organism living within the body
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 enables herbs, shrubs, and trees to
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 minimum length.
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? Researchers at the University of Twente have
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 or throughout the whole organism.
In 1066, England was invaded by multiple foreign powers. A northern force led by King Harald Hardrada of Norway advanced on York via the River Humber, while a southern force, led by Duke William of Normandy (later William I the Conqueror) crossed the Channel with forces from

The blobfish, once considered the ugliest animal in the world, has since had quite the redemption arc. Years after it was first discovered, scientists realized that the deep-sea creature appeared so unnervingly blobby only because it went through an extreme change in pressure
Arthropod-borne viruses (arboviruses), such as dengue and Zika viruses, transmit widely across the globe, posing threats to human health and biosecurity. They spread through the bites of arthropod vectors, moving between insects and vertebrate hosts. To sustain their
For decades, scholars have estimated the ideology of members of Congress by analyzing roll-call votes, recorded tallies of each member's "yea-or-nay" on legislation. But a new study from the University of Chicago's Harris School of Public Policy finds this method is likely
Prolonged exposure to microplastics can disrupt vital physiological processes in gorgonians, such as respiration. Although these pollutants do not cause visible damage to tissues and cells, their effects could have an ecological impact on these organisms that structure the
Stellar streams are trails of stars that astronomers can study to solve mysteries about the history of our Milky Way galaxy and, potentially, the dark matter that helps shape the cosmos despite eluding direct observation. These streams have largely been left behind by small
New UNLV-led research is helping to unravel clues to a cosmic mystery that has eluded scientists for decades. Cataclysmic variables (CVs) are binary star systems in which primary stars—incredibly dense and compact white dwarfs—accumulate material from nearby companion stars.
The name might sound like a Nordic god, but it is actually the molecular machinery that allows many different species to eat and grow: fungi, plants, whales, humans, flies. It is the mighty TOR protein. An expedition to Easter Island half a century ago led to its discovery, and
