Visible to the naked eye in the constellation Cassiopeia, the star γ Cas has puzzled astrophysicists for half a century. It emits X-rays of an intensity and temperature incompatible with what one would expect from an ordinary massive star.…
Researchers from Xi'an Jiaotong-Liverpool University (XJTLU) in China have developed a streamlined process that makes it easier to produce tiny therapeutic particles released by cells, called exosomes, which are being explored as a new…
Each year, antimicrobial resistance (AMR) is responsible for an estimated 1.1 to 1.4 million deaths worldwide. Now, scientists have found evidence that the spread of AMR isn't always driven by bacteria evolving to resist the antibiotics…
A new data visualization illustrates how an experimental NASA technology can provide extra lead time to communities in the path of a tsunami. Called GUARDIAN (GNSS Upper Atmospheric Real-time Disaster Information and Alert Network), the…
Worries about the British economy have long been dominated by one persistent concern—weak productivity. Since the financial crisis of 2008, growth has stagnated, leaving the UK trailing well behind the US, France and Germany across that…
Unless your employer is Lumon Industries, where the "Severance" workday never ends, a canceled meeting can feel like a gift of limitless time. A Rutgers University study published in the Journal of the Association for Consumer Research…
Hollywood loves a comeback story: a director who flopped and then returned with a masterpiece or the producer who went bust and bounced back with a winner. It's a narrative rooted in the business belief that failure is a great teacher. But…
During a widespread crisis, negative emotions don't simply go away once the workday begins. Organizational scholars who study how emotions affect employees tend to assume that negative emotions equal negative outcomes. That isn't always…
New research finds the addition of a thousand new immigrants in a metropolitan area reduces elderly mortality by about 10 deaths than would be typical. Why? Because among the newcomers are foreign-born health care workers who are arriving…
A new Caltech study indicates that drought increases the abundances of antibiotic-resistant microorganisms in soils, which directly correlates with an increase in antibiotic-resistant infections in hospitals. In other words, regions…
A research team led by the Museum für Naturkunde presents the first evidence that several bat species produce courtship songs in the immediate rotor-swept zone of wind turbines while circling around the nacelle. Data from over 80,000 audio…
A new biosensor developed at the Department of Energy's Oak Ridge National Laboratory detects the emerging presence of fungus on plants at the molecular level, paving the way for next-generation crop protection and the development of…
For the last few decades, researchers have been studying what the universe looked like in its first seconds. It is generally accepted that the universe expanded exponentially in the first fraction of a second after the Big Bang.…
A stark rise in the number of stray dogs being euthanized across the UK and the Republic of Ireland, with rates more than tripling over a three-year period, are revealed in a new collaborative study. The research is published in Animals.
A paper published in the journal Quaternary International reveals a distinctive technological behavior at level TD10.2-BB of Gran Dolina (Atapuerca, Burgos), characterized by the almost exclusive use of local chert and linked to one of the…
In the earliest phase of creating human proteins, the protein complex NAC performs an essential task by starting the first steps toward folding proteins into their correct three-dimensional structures. An international research team led by…
Researchers from the Earlham Institute, in collaboration with the Department of Biology at the University of Oxford, have discovered three previously unrecognized lineages of the protist Bodo, each with its own bacterial endosymbiont (a…
Plants need water, light, and air to thrive. But when they transport water from the soil up to their leaves, they defy gravity. Scientists describe this astonishing phenomenon as "negative water potential," a form of negative tension that…
In nature, a certain size is often a prerequisite for biomolecules to perform their specific functions. For example, for proteins or DNA to fulfill their vital tasks, they must be folded in a precise manner—and this requires a certain…
Some materials behave unexpectedly. They crack differently than expected, or react in ways that are hard to explain. The answer often lies in their atomic structure. Is it neatly arranged, as in a crystal, or disordered, as in glass?…
In conventional pathology and physiology research, two-dimensional (2D) analysis—observing thinly sliced tissue sections—has been mainstream, making it difficult to comprehensively understand the distribution of cells across entire organs…
In 1066, England was invaded by multiple foreign powers. A northern force led by King Harald Hardrada of Norway advanced on York via the River Humber, while a southern force, led by Duke William of Normandy (later William I the Conqueror)…
Findings from a new University of Cincinnati study have reshaped the fundamental understanding of how a certain cell organelle prepares its environment for cellular digestion. The study, led by UC's Jiajie Diao, Ph.D. and published in Cell…
A high-pressure method of instantaneously freezing cells has proven to be effective in the first empirical validation of its kind. Through further development, the method holds promise in finding broad applications in regenerative medicine…
Gallium nitride, a semiconductor that can operate at high voltages, temperatures, and frequencies, has enabled technologies from LED lighting to high-power electronics. Now Cornell researchers have observed a quantum property of the…
Cornell scientists have engineered E. coli to act as a sensitive biosensor for monitoring environmental arsenic, a toxic pollutant most notably found in rice paddies in Southeast Asia. Their new study provides a proof of principle for a…
After smashing March heat records in 14 states and the U.S. as a whole, the gigantic heat dome that's baked the Southwest is creeping eastward and may end up being one of the most expansive heat waves in American history, meteorologists…
The blobfish, once considered the ugliest animal in the world, has since had quite the redemption arc. Years after it was first discovered, scientists realized that the deep-sea creature appeared so unnervingly blobby only because it went…
Arthropod-borne viruses (arboviruses), such as dengue and Zika viruses, transmit widely across the globe, posing threats to human health and biosecurity. They spread through the bites of arthropod vectors, moving between insects and…
For decades, scholars have estimated the ideology of members of Congress by analyzing roll-call votes, recorded tallies of each member's "yea-or-nay" on legislation. But a new study from the University of Chicago's Harris School of Public…
