While atomic clocks are already the most precise timekeeping devices in the universe, physicists are working hard to improve their accuracy even further. One way is by leveraging spin-squeezed states in clock atoms.

The English language is famous for the large number of words that express the idea of being drunk in a humorous way—so-called drunkonyms like "pissed," "hammered" or "wasted." British comedian Michael McIntyre even argues in a comedy routine that posh people can use any word to mean "drunk" in English, e.g., "I was utterly gazeboed" or "I'm gonna get totally carparked." With the myriad of possibilities, how can people understand new drunkonyms then?

Changes to the social and political landscape between 2011 and 2018, with dramatic events such as DACA rule changes, new presidential leadership, immigration bills and more, have left one major threat looming—deportation.

Inspired by the color-changing ability of chameleons, researchers have developed a sustainable technique to 3D-print multiple, dynamic colors from a single ink.

Hydrogels are versatile biomaterials conquering an increasing number of biomedical areas. Consisting of water-swollen molecular networks that can be tailored to mimic the mechanical and chemical features of various organs and tissues, they can interface within the body and on its outer surfaces without causing any damage to even the most delicate parts of the human anatomy.

Atmospheric rivers (ARs) are filaments of intense moisture transport in the atmosphere. These weather systems drive a large fraction of the extreme precipitation events over coastal regions. Detecting ARs in satellite observations has long been a challenging task due to the lack of wind information. In a study published in the Journal of Geophysical Research: Atmospheres, scientists derived an approximation of the 3-dimensional (3D) wind field based on the spatial distribution of the satellite-based temperature.

Japanese horseshoe bats—or Nihon Kikugakushira—emit high-amplitude, ultrasonic waves from their nostrils. Several ultrasound-related studies have previously attempted to address the significant regional variability noted in bats' nasal morphologies, without yielding conclusive results.

Roughly 14,500 to 10,500 years ago, in the transition from the last glacial period, Epipaleolithic and Neolithic peoples harvesting vegetation from the wetlands of eastern Jordan created a habitat for birds that would otherwise have migrated, a new study published in the Journal of Archaeological Method and Theory reveals.

Charles Darwin University (CDU) researchers and First Nations Yugul Mangi Rangers have discovered a new population of a rare and threatened shark species in the Northern Territory's Roper River.

As NASA works to develop all the systems needed to return astronauts to the moon under its Artemis campaign for the benefit of all, the SLS (Space Launch System) rocket will be responsible for launching astronauts on their journey. With the liquid oxygen tank now fully welded, all of the major structures that will form the core stage for the SLS rocket for the agency's Artemis III mission are ready for additional outfitting.

News of a possible Russian satellite-destroying, space-based nuclear weapon sent shock waves through Washington this week. Some officials responded with considerable alarm, while others insisted that such concern is—for the moment—an overreaction.

Until recently, Orthacanthus gracilis could have been considered the "John Smith" of prehistoric shark names, given how common it was.

Researchers have discovered not only microplastics but also a higher abundance of cellulose-based fibers in the intestine samples of four apex shark species caught off the coast of South East Queensland (SEQ).

What if one of the things known for helping and reducing stress and anxiety, becomes such a commitment, it leads to burn-out?

In-depth research of two of Australia's dolphin species shows how their behaviors have evolved to co-exist and form mixed-species groups in northwestern Australia.

In their recent publication in Nature Water, D-BAUG researchers Junyang Gou and Professor Benedikt Soja introduced a finely resolved model of terrestrial water storage using a novel deep learning approach.

A collaborative project has made a breakthrough in enhancing the speed and resolution of widefield quantum sensing, leading to new opportunities in scientific research and practical applications.

Amache National Historic Site in southeastern Colorado is officially America's newest national park, the National Park Service announced Thursday.

The last round of atmospheric river storms drenched Southern California with historic rainfall, and by one measure, it came close to beating a record for the most rain over a three-day period.

Anoxic marine basins may be among the most viable places to conduct large-scale carbon sequestration in the deep ocean, while minimizing negative impacts on marine life. So say UC Santa Barbara researchers in a paper published in the journal AGU Advances.

NASA was riding a high after the overall success of Artemis I when the uncrewed rocket made a test run to the moon and back in 2022, so the message remained full steam ahead to push for a crewed Artemis II flight in 2024 and the return of humans to the moon in 2025.

The Department of Defense is looking for a new home for SpaceX's Starship, launching the process to determine what the environmental impact would be to allow the world's most powerful rocket to launch from Florida's Space Coast.

A study recently submitted to The Astronomical Journal continues to search for the elusive Planet Nine (also called Planet X), which is a hypothetical planet that potentially orbits in the outer reaches of the solar system and well beyond the orbit of the dwarf planet, Pluto.

A new study shows that nature-based solutions are crucial to mitigate climate change, but only if they go hand in hand with a drastic reduction in greenhouse gas emissions.

Uncovering the biochemical mechanisms underlying different types of cell death has the potential to provide targets for the treatment of various diseases. A physiological cytokine combination (TNF+IFNγ) has been identified that induces cell death in several cell lines in vitro. However, because TNF and IFNγ are multi-effector cytokines, their individual and combined use has complex effects. In disease situations, it is difficult to distinguish which effects are triggered by TNF+IFNγ cell death.
