Phys.org / Space telescopes track nearby quasar's dramatic X-ray state transition
By analyzing the data from various space observatories, Chinese astronomers have inspected a nearby quasar designated SDSS J000532.84+200717.4. Results of the new study, published April 1 on the arXiv preprint server, shed ...
Dialog / Scientists build arsenic-lined crystal pore framework to boost rhodium catalyst performance
Rhodium is one of the most powerful catalytic metals known to chemistry. Small amounts of it can drive reactions that produce millions of tons of useful chemicals every year. But getting rhodium to work well—quickly, selectively, ...
Phys.org / Advanced mirror technology now powers a breakthrough X-ray telescope
Scientists in Japan have developed a high-resolution X-ray telescope sharp enough to distinguish an object just 3.5 mm wide from one kilometer away, by combining precision mirror-making technology with space astronomy. To ...
Phys.org / How Artemis II's Earthset photo compares with the iconic Earthrise image from 1968
As NASA's Artemis II mission completed its lunar flyby, the astronauts sent back a stunning image of the colorful Earth setting behind the moon. This breathtaking photo, called Earthset, draws inevitable comparisons with ...
Phys.org / From Jurassic Park to dreams of AI doom, pop culture shapes science more than we like to admit
The relationship between science and pop culture often looks like a one-way street: scientific discoveries inspire films, television and novels, particularly in science fiction. But the relationship really goes both ways, ...
Phys.org / Electrode technology achieves 86% efficiency for converting CO₂ into plastic precursors
In the process of converting carbon dioxide into useful chemicals such as ethylene—a key precursor for plastics—a major challenge has been the flooding of electrodes, where electrolyte penetrates the electrode structure and ...
Phys.org / Embryo fossil found in South Africa is world's oldest proof that mammal ancestors laid eggs
Between 280 and 200 million years ago, a group of animals evolved which would eventually give rise to mammals, including humans: the therapsids. They were first described more than 150 years ago, based on fossils from South ...
Medical Xpress / Immune cells in the nose slow influenza virus, study finds
A new study from the University of Gothenburg may help guide the development of better influenza vaccines. Memory cells in the nose slow the influenza virus as soon as it enters the body. They reduce viral levels and may ...
Phys.org / How does spider venom damage human cells? Researchers uncover the killer mechanism of recluse spider toxin
Spiders are among Earth's most resourceful predators, nabbing prey by any means necessary. Orb weavers spin webs for capture. Wolf spiders ambush on the ground at night. Almost all spiders use venom when they hunt.
Medical Xpress / New study shows linens, not equipment emissions, dominate ultrasound's carbon footprint
A new research study published in the Journal of the American College of Radiology (JACR) has found that unlike other modalities, linens and disposable supplies account for the vast majority of ultrasound's annual carbon ...
Medical Xpress / Heart, metabolic and inflammatory risk patterns found to differ markedly between men and women with obesity
New research being presented at this year's European Congress on Obesity (ECO) in Istanbul, Turkey (May 12–15), reveals distinct patterns of heart, metabolic, and inflammatory health risks between men and women living with ...
Medical Xpress / A new sepsis drug target: Boosting a chloride channel helps immune cells kill bacteria
A research team has discovered a previously unknown mechanism by which the immune system fights bacterial infections. The scientists found that a specific protein, the chloride channel PACC1, is crucial for immune cells to ...
