An international team‚ including Western astrophysicists Els Peeters and Jan Cami‚ has found the destruction and re-formation of a large quantity of water in a planet-forming disk located at the heart of the Orion Nebula.

Chromatin is a unique DNA and protein complex that makes up the chromosomes. Specific proteins (histones) wind up the DNA like small cable drums to package the long DNA. A cable drum (consisting of four pairs of histones) with coiled DNA is called a nucleosome and is the smallest unit of chromatin.

A new analysis by the STAR collaboration at the Relativistic Heavy Ion Collider (RHIC)‚ a particle collider at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory‚ provides the first direct evidence of the imprint left by what may be the universe's most powerful magnetic fields on "deconfined" nuclear matter. The evidence comes from measuring the way differently charged particles separate when emerging from collisions of atomic nuclei at this DOE Office of Science user facility.

Nature is amazing. It has developed in living organisms the ability to regulate complex biochemical processes with remarkable efficiency. Enzymes‚ natural catalysts‚ play a pivotal role in this regulation‚ ensuring the fulfillment of various physiological needs throughout a cell's lifespan.

Iron is a micronutrient for plants. Biologists from the Institute of Botany at Heinrich Heine University Düsseldorf (HHU) describe in a study‚ which has now been published in the Journal of Cell Biology‚ that regulatory proteins for iron uptake behave particularly dynamically in the cell nucleus when the cells are exposed to blue light—an important signal for plant growth. They found that the initially homogeneously distributed proteins relocated together into "biomolecular condensates" in the cell nucleus shortly after this exposure.

A team of researchers from The University of New Mexico's Museum of Southwestern Biology (MSB) have reported unexpectedly high levels of chemical contamination in wild birds and mammals at Holloman Air Force Base‚ near Alamogordo‚ N.M. in new research published in Environmental Research.

From smart virtual assistants and self-driving cars to digital health and fraud prevention systems‚ AI technology is transforming almost every aspect of our daily lives—and education is no different. For all its promise‚ the rise of AI‚ like any new technology‚ raises some pressing ethical and equity questions.

In our data-driven era‚ solving complex problems efficiently is crucial. However‚ traditional computers often struggle with this task when dealing with a large number of interacting variables‚ leading to inefficiencies such as the von Neumann bottleneck. A new type of collective state computing has emerged to address this issue by mapping these optimization problems onto something called the Ising problem in magnetism.

Warmer soils harbor a greater diversity of active microbes‚ according to a new study from researchers at the Centre for Microbiology and Environmental Systems Science (CeMESS) at the University of Vienna.

Understanding cloud patterns in our changing climate is essential to making accurate predictions about their impact on society and nature. Scientists at the Institute of Science and Technology Austria (ISTA) and the Max-Planck-Institute for Meteorology published a study in the journal Science Advances that uses a high-resolution global climate model to understand how the clustering of clouds and storms impacts rainfall extremes in the tropics. They show that with rising temperatures‚ the severity of extreme precipitation events increases.
