Astronomers have discovered a supermassive black hole at the center of a galaxy just 1.5 billion years after the Big Bang that is consuming matter at a phenomenal rate -- over 40 times the theoretical limit. While short lived, this black hole's 'feast' could help astronomers explain how supermassive black holes grew so quickly in the early Universe. Read more ›

New research has found that, unlike birds, the evolution of bats' wings and legs is tightly coupled, which may have prevented them from filling as many ecological niches as birds. Read more ›

Researchers developed citizen science platforms as a new data source to evaluate the effectiveness of the 742 protected areas for birds across Germany. This research shows that although these areas are well placed, their effectiveness varies greatly. Read more ›

Is the floating freshwater fern commonly called Carolina azolla the potential answer to global food insecurity or a possible threat to humanity? On the heels of a study published earlier this year on the plant's nutrition and digestibility, a team learned of concerns about the plant's potential toxin content. The researchers joined an international effort to test Azolla and found that it does not contain cyanotoxins, potent toxins produced by... Read more ›

As critical responders, macrophages can perceive helpful biotechnology as threats. If not created with the right materials or mechanical forces, these devices can trigger an immune response that can cause inflammation, scar tissue or device failure. Read more ›

When light conditions rapidly change, our eyes have to respond to this change in fractions of a second to maintain stable visual processing. This is necessary when, for example, we drive through a forest and thus move through alternating stretches of shadows and clear sunlight. In situations like these, a corrective mechanism is required. Such a corrective 'gain control' mechanism exists in the fruit fly Drosophila melanogaster, where it acts... Read more ›

Relief-type cultural heritage objects are commonly found in many historical sites worldwide, but often suffer from varying levels of damage and deterioration. Traditional methods for image reconstruction require extensive manual labor and specialized knowledge. Now, researchers have developed a novel neural network model that can reconstruct these reliefs as three-dimensional digital images from old photographs containing their pre-damage information. This innovative technology paves the way for accurate di Read more ›

For Halloween, the European Southern Observatory (ESO) reveals a spooktacular image of a dark nebula that creates the illusion of a wolf-like silhouette against a colourful cosmic backdrop. Fittingly nicknamed the Dark Wolf Nebula, it was captured in a 283-million-pixel image by the VLT Survey Telescope (VST) at ESO's Paranal Observatory in Chile. Read more ›

Sleep apnea, a common yet underdiagnosed sleep disorder, contributes to the development of dementia among adults -- particularly women, a new study suggests. At every age level, women with known or suspected sleep apnea were more likely than men to be diagnosed with dementia. Read more ›

Researchers have developed a model to calculate how quickly or slowly an organism should ideally learn in its surroundings. An organism's ideal learning rate depends on the pace of environmental change and its life cycle, they say. Read more ›
