Phys.org / Scorching climate drove lampreys apart during Cretaceous period, DNA and fossil record reveal
A new study finds that one of the hottest periods in Earth's history may have driven lampreys apart—genetically speaking. The work could have implications for how aquatic species respond to our current changing climate. ...
Phys.org / Roman-era dog penis bone painted red discovered in ancient quarry shaft
A bio-archaeologist with the University of Reading, in the U.K., has found an ancient dog's red-painted penis bone along with a trove of other bones, in an ancient Roman era quarry shaft. In her paper published in the Oxford ...
Phys.org / Proximity effect enables non-ferroelectric materials to gain new properties
Ferroelectrics are special materials with polarized positive and negative charges—like a magnet has north and south poles—that can be reversed when external electricity is applied. The materials will remain in these reversed ...
Phys.org / Physicists achieve simulation of non-Hermitian skin effect in 2D with ultracold fermions
A research team led by The Hong Kong University of Science and Technology (HKUST) has achieved a groundbreaking quantum simulation of the non-Hermitian skin effect in two dimensions using ultracold fermions, marking a significant ...
Phys.org / Young salmon may face hungry new competition from juvenile sablefish along northwest coast
There is a new mouth to feed in the coastal waters of the Northwest where juvenile salmon first enter the ocean, and it's a hungry one.
Phys.org / Crafting the perfect bite of meat: Engineers develop metamaterials that mimic muscle and fat architecture
In a new publication in Nature Communications, Israeli and Palestinian engineers from The Hebrew University of Jerusalem pioneered the use of metamaterials to create whole cuts of meat. The work leverages cutting-edge materials ...
Phys.org / Toxin-antitoxin systems could target invasive and resistant bacteria
In a counterintuitive move, bacteria are known to produce self-destructive toxins. However, they also make antitoxins, and researchers at Lawrence Livermore National Laboratory (LLNL) have identified these toxin-antitoxin ...
Phys.org / Just 7% of male humpback whales in New Caledonia may have fathered offspring
A small international team of marine mammal scientists has found evidence that just 7% of the male humpback whales residing near New Caledonia, in the southwest Pacific, may have fathered offspring. For their project, reported ...
Phys.org / Dormancy: Life's first survival strategy?
The early Earth was an extreme place. Asteroids pommeled the surface. Volcanoes spewed lava and carbon dioxide. The thick, toxic atmosphere lacked oxygen. Yet, in this turmoil, life emerged.
Phys.org / A quarter of freshwater species face extinction: Study
A quarter of freshwater animals, including fish, insects and crustaceans, are at high risk of extinction due to threats including pollution, dams and farming, according to a new study published on Wednesday.
Phys.org / Scientists find evidence that ancient 'hotspot' played major role in formation of Great Lakes
A trio of Earth and atmospheric scientists at the University of Houston, working with a geoscientist from the University of Arizona, has found evidence that a geographic hotspot laid the groundwork for the formation of the ...
Phys.org / The hidden mechanics of earthquake ignition: How slow, silent stress release is prelude and trigger for seismic activity
A new study has unraveled the hidden mechanics of how earthquakes ignite, shedding light on the mysterious transition from quiet, creeping motion to the violent ruptures that shake the Earth.
