X-ray emissions from black hole jets vary unexpectedly, challenging leading model of particle acceleration
Researchers discovered only relatively recently that black hole jets emit X-rays, and how the jets accelerate particles to this high-energy state is still a mystery. Surprising new findings in Nature Astronomy appear to rule out one leading theory, o.....»»
Ingestible capsule to address GI tract diseases
Diagnosing and treating gastrointestinal tract diseases can be notoriously invasive and time-consuming: blood and stool lab work; biopsies, colonoscopies and endoscopies; and X-rays, CT scans and MRI imaging. But what if there was an alternative as s.....»»
Helium nuclei research advances our understanding of cosmic ray origin and propagation
Much of our understanding of the universe and its mysterious phenomena is based on theoretical interpretations. In order to deepen the understanding of distant objects and energetic phenomena, astronomers are looking at cosmic rays, which are high-en.....»»
"Segment-jumping" ridgecrest earthquakes explored in new study
On the morning of July 4, 2019, a magnitude 6.4 earthquake struck the Searles Valley in California's Mojave Desert, with impacts felt across Southern California. About 34 hours later on July 5, the nearby city of Ridgecrest was struck by a magnitude.....»»
Astronomers explore a recently discovered luminous quasar
Using various space telescopes, an international team of astronomers have observed a recently detected luminous quasar known as SMSS J114447.77-430859.3, or J1144 for short. Results of the observational campaign, available in the July 2023 edition of.....»»

New study reveals possible future health impacts related to climate mitigation
Reduce fossil fuel use and air quality will improve, right? It might not be as straightforward as it appears, according to a Penn State-led research team. They explored almost 30,000 simulated future scenarios and found that some climate mitigation e.....»»
Innovative imaging technique uses the quantum properties of X-ray light
An international team of researchers including scientists from FAU has, for the first time, used X-rays for an imaging technique that exploits a particular quantum characteristic of light. In their article, which has now been published in the journal.....»»
An X-ray look at the heart of powerful quasars
Researchers have observed the X-ray emission of the most luminous quasar seen in the last 9 billion years of cosmic history, known as SMSS J114447.77-430859.3, or J1144 for short. The new perspective sheds light on the inner workings of quasars and h.....»»
Researchers use structured light on a chip in another photonics breakthrough
In everyday life we experience light in one of its simplest forms—optical rays or beams. However, light can exist in much more exotic forms. Thus, even beams can be shaped to take the form of spirals; so-called vortex beams, endowed with unusual pr.....»»
How well do interventions that include a case manager help individuals experiencing homelessness?
A recent analysis of published studies examined a wide range of interventions that include a case manager to help individuals experiencing homelessness find stable housing. The analysis, which is published in Campbell Systematic Reviews, explored com.....»»
Cosmic rays reveal hidden ancient burial chamber underneath Naples
Rectangular chamber was probably the tomb of a wealthy individual or family. Enlarge / Archaeologists used cosmic rays to detect a secret underground burial chamber from the Hellenistic period in Naples, circa late fourth century.....»»
Crushed clams, roaming rays: Acoustic tags reveal predator interactions
Clam leases are designated underwater locations used to produce hard clams of all sizes from littlenecks to chowders. Clam production or aquaculture can be a risky business due in part to unwanted marine intruders. Among them, stealthy and highly mob.....»»
Study finds the brains of modern dog breeds are larger than those of ancient breeds
Modern dog breeds that are genetically more distant from wolves have a relatively larger brain size compared to ancient breeds that are thousands of years old, according to the findings of Hungarian and Swedish researchers. The increase in brain size.....»»
Astronomers puzzled by "largest" ever cosmic explosion
Astronomers said on Friday they have identified the "largest" cosmic explosion ever observed, a fireball 100 times the size of our Solar System that suddenly began blazing in the distant universe more than three years ago......»»
A highly performing device for polariton-based coherent microwave emission and amplification
When light strongly interacts with matter, it can produce unique quasi-particles called polaritons, which are half light and half matter. In recent decades, physicists explored the realization of polaritons in optical cavities and their value for the.....»»
Neutron star"s X-rays reveal "photon metamorphosis"
