How nearby galaxies form their stars
Stars are born in dense clouds of molecular hydrogen gas that permeates interstellar space of most galaxies. While the physics of star formation is complex, recent years have seen substantial progress towards understanding how stars form in a galacti.....»»
Team develops promising new form of antibiotic that makes bacterial cells self-destruct
To address the global threat of antibiotic resistance, scientists are on the hunt for new ways to sneak past a bacterial cell's defense system. Taking what they learned from a previous study on cancer, researchers from the University of Toronto (U of.....»»
How the Malleus Maleficarum fueled the witch trial craze
Invention of printing press, influence of nearby cities created perfect conditions for social contagion. Between 1400 and 1775, a significant upsurge in witch trials swept across.....»»
Physicists show that neutron stars may be shrouded in clouds of axions
A team of physicists from the universities of Amsterdam, Princeton and Oxford have shown that extremely light particles known as axions may occur in large clouds around neutron stars. These axions could form an explanation for the elusive dark matter.....»»

A near-Earth microquasar emerges as a source of powerful radiation
Modern astronomy has clung to the belief that the relativistic outflows or jets, responsible for the existence of electromagnetic radiation of particularly high energies, are located in the nuclei of active galaxies distant from Earth. However, a dif.....»»
"Old" star could provide new insights into star evolution
A newly discovered star could challenge some models of how stars evolve and the way they produce elements as they age......»»

Hubble captures intricacies of R Aquarii, a symbiotic binary star roughly 700 light-years from Earth
The NASA/ESA Hubble Space Telescope has provided a dramatic and colorful close-up look at one of the most rambunctious stars in our galaxy, weaving a huge spiral pattern among the stars. Hubble's images capture its details and its evolution is featur.....»»
Firms with green innovation patents rewarded in the credit market, finds study
A Queensland University of Technology (QUT) study of the US credit default swap (CDS) market's response to green innovation in the form of green patents found that firms with more green patents had lower borrowing costs and higher credit ratings......»»
Hubble captures image of a spectacular ‘stellar volcano’
Hubble has homed in on a nearby star called R Aquarii, which is throwing out material for billions of miles around it......»»
Could ‘Early Dark Energy’ Resolve the Mystery of Cosmic Expansion?
Estimates of how fast the universe is expanding disagree. Could a new form of dark energy resolve the problem?.....»»
Zoom into the first page of ESA Euclid"s great cosmic atlas
On 15 October 2024, ESA's Euclid space mission revealed the first piece of its great map of the universe, showing millions of stars and galaxies......»»
Dutch students warn space mission of noisy white dwarfs
The background noise of gravitational waves from orbiting white dwarf stars will be stronger than the noise from binary black holes. This is what two Dutch master's students and their supervisor predict in two papers in anticipation of the LISA space.....»»
Revealing the hidden universe with full-shell X-ray optics
The study of X-ray emission from astronomical objects reveals secrets about the universe at the largest and smallest spatial scales. Celestial X-rays are produced by black holes consuming nearby stars, emitted by the million-degree gas that traces th.....»»
Each glacier has a unique organic matter composition, study reveals
Melting glaciers release more than just water. Organic matter once trapped in ice can run into streams and rivers, where it becomes food for microbes. These organisms respire the organic matter back to the atmosphere in the form of carbon dioxide, wi.....»»
Microtubule formation mechanism sheds light on how cells build their internal skeleton
Inside every cell, a network of tiny filaments, called the microtubule cytoskeleton, helps maintain the cell's shape, allows it to divide, and transports vital materials from one part of the cell to another. The filaments that form this network, term.....»»
3D printing method could improve micro energy storage
One key to making portable devices more compact and energy efficient lies in the precise nanoscale form of energy-storing capacitors. Researchers in Sweden report they've cracked the challenge with a unique 3D printing method......»»
Strangler figs prefer large host trees, study finds
The strangler fig, as a hemi-epiphyte, is renowned for its unique "strangling" behavior. Its colonization and establishment on some trees in tropical urban green spaces form a distinctive ecological landscape, enriching the ecological functions of ci.....»»
Study suggests that "Jedi" rodents remotely move matter using sound to enhance their sense of smell
Scientists have debated the purpose of the ultrasonic vocalizations (USVs) produced by rodents since the discovery of these sounds in the 1950s. There's a wide research consensus suggesting USVs are a form of social communication, a courtship display.....»»
