Human activities add large quantities of nitrogen to the environment, much of which gets washed into streams and rivers. These waterways transport some of that nitrogen to the oceans, but they also remove a significant portion of it through a process called denitrification:
Native trees, such as oaks, have long held a special place in our culture and countryside. Now, researchers have shown that these trees are also important to woodland birds and their offspring.
Cowboys guided a herd of longhorn cattle through downtown Denver to celebrate the opening of the annual National Western Stock Show on Jan. 8, 2026. As ranchers bring their best cattle to compete for blue ribbons over the course of this month, it's a good time to consider
New research from James Cook University has made the extraordinary discovery that epaulette sharks can reproduce and lay eggs without any measurable rise in energy use.
A new study shows that generative AI is already being used to "bring back" the dead, as entertainment icons, as political witnesses, and as everyday companions for grieving families. Tracing cases of AI "resurrections," the study claims this practice isn't just emotionally
Soils store more carbon than the atmosphere and vegetation combined, with soil microorganisms playing the main role. As a result, the global soil carbon cycle—by which carbon enters, moves through, and leaves soils worldwide—exerts a significant impact on climate change feedback.
Nanomechanical systems developed at TU Wien have now reached a level of precision and miniaturization that will allow them to be used in ultra-high-resolution atomic force microscopes in the future. Their new findings are published in the journal Advanced Materials Technologies.
In a study published in Cell Research, researchers have identified a fibrous-layer resident subpopulation of P-SSCs labeled by Angptl7. They found that these cells are crucial for bone fracture repair by mediating endochondral ossification, but exhibit minimal osteogenic

Researchers from the Wilmer Eye Institute, Johns Hopkins Medicine Center for Nanomedicine—which designs nanotechnology-based platforms for clinical translation across specialties—developed a strategy for delivering therapeutic messenger RNA (mRNA) to the inner lining of the
As we prepare for missions beyond Earth orbit, one crucial challenge remains: keeping astronauts healthy in microgravity. Without daily exercise, their muscles, bones and cardiovascular systems weaken, which could impact mission success and astronaut safety, especially in
Girls between the ages of 13 and 19 are widely exposed to beauty content online that promotes products unsuitable for young skin—even when they are not actively seeking beauty-related information. Moreover, they believe that other girls (rather than themselves) may become

Whether in a smartphone or laptop, semiconductors form the basis of modern electronics and accompany us constantly in everyday life. The processes taking place inside these materials are the subject of ongoing research. When the electrons in a semiconductor material are
Peer reflection on microteaching plays a crucial role in teachers' training programs as it equips novice teachers with opportunities to understand their peers' practices. It enhances their reflective thinking, teaching awareness, and bridges the gap between theoretical and
The kidney's proximal tubule reabsorbs water, glucose, ions and other small molecules from the urine and thus maintains the body's supply of these essential constituents. The tubule can be easily damaged by ischemia, or poor circulation, but it normally can repair itself.
Researchers from Skoltech have uncovered physical principles governing the remote "tuning" of nanocatalysts, where the ultra-thin platinum layer's properties can be controlled exclusively by modifying its metallic core's composition and structure.
Climate change has a wide range of effects on wildlife. It affects seasonal migration, reproduction times, body size and mass, and disrupts ecological processes, thereby posing challenges for the populations of some species. An international team of scientists has now analyzed
Physicists have uncovered a link between magnetism and a mysterious phase of matter called the pseudogap, which appears in certain quantum materials just above the temperature at which they become superconducting. The findings could help researchers design new materials with
A new study published in the Proceedings of the National Academy of Sciences reveals that organized civil society and social mobilization are key, yet often unrecognized, agents of global biodiversity conservation. By analyzing a global dataset of 2,801 socio-environmental
Over the years, passing spacecraft have observed mystifying weather patterns at the poles of Jupiter and Saturn. The two planets host very different types of polar vortices, which are huge atmospheric whirlpools that rotate over a planet's polar region. On Saturn, a single
The climate warmed up almost as quickly 56 million years ago as it is doing now. When a huge amount of CO2 entered the atmosphere in a short period of time, it led to large-scale forest fires and erosion. Mei Nelissen, Ph.D. candidate at NIOZ and UU, and her colleagues were
People in northern Germany flocked to the Elbe river Monday to marvel at giant Arctic-style ice floes that have clogged up a stretch of the waterway, creating a headache for shipping but delighting visitors.
Bacteriophages have been used therapeutically to treat infectious bacterial diseases for over a century. As antibiotic-resistant infections increasingly threaten public health, interest in bacteriophages as therapeutics has seen a resurgence. However, the field remains largely
Wildfires that have killed 19 people in southern Chile and wiped out entire towns, raged for a third day Monday, fanned by high temperatures and strong winds at the height of the southern hemisphere summer.
The CP2K open-source package is among the top three most widely used research software suites worldwide for simulating the behavior of atoms and molecules. Among other applications, CP2K plays an important role in generating data used to train artificial intelligence (AI)-based

The chytrid fungus (Batrachochytrium dendrobatidis), or Bd for short, is considered one of the causes of the worldwide decline in amphibian populations. In recent years, researchers have identified different genetic strains of the fungus that causes chytridiomycosis in various
The early stage of giant telescope development involves a lot of horse-trading to try to appease all the different stakeholders that are hoping to get what they want out of the project, but also to try to appease the financial managers that want to minimize its cost. Typically,
Every day, we quietly judge the people around us. Did that co-worker split the credit fairly? Did a neighbor return a lost package? Did someone cut in line or respect the rules?
A Czech and Spanish-led research team has demonstrated the ability to distinguish subtle differences between magnetic ground states using a new form of scanning probe microscopy.
An international team of researchers has systematically measured the β-decay half-lives of 40 nuclei near calcium-54, providing key experimental data for understanding the structure of extremely neutron-rich nuclei.
