Phys.org / Nullarbor mapping reveals surface signs of deep, hidden cave systems
Mysterious trenches stretching for kilometers across southern Australia's Nullarbor Plain have been revealed as the surface footprints of deep, hidden ancient cave systems.
Phys.org / Capybaras in the desert? Fossil casts doubt on Atacama as world's oldest continuously dry region
Ask any zoo-goer and they will tell you that capybaras are adorable. Ask a scientist specializing in the rodents, which resemble oversized guinea pigs, and they will tell you they are obligate semiaquatic herbivores that ...
Phys.org / Electron and photon beams drive same gold-forming reaction toward different nanoscale structures
Beauty and mystery—it is hard to imagine a more alluring combination, and this is precisely what we encounter when we observe phenomena in the nanoworld. But are we really sure that observations made using modern microscopic ...
Phys.org / Portable metasurface biosensor turns molecular signals into images, bypassing spectrometers
What if signs of disease could be detected using nothing more than a tiny chip that fits in the palm of your hand and a camera, without ever visiting a hospital? A scene that once seemed possible only in science fiction has ...
Phys.org / Black holes from stellar to supermassive size may follow one jet-launching rule
An early-career Western Australian astrophysicist has helped uncover a universal rule behind one of the most powerful behaviors in the universe: when black holes launch jets. The discovery, published in the journal Nature ...
Phys.org / Disorder is key to tuning a high-temperature superconductor
Cornell physicists have discovered that minimizing disorder, not varying electron count, is the key factor for controlling superconductivity in the unique material iron selenide (FeSe), a new insight for understanding high-temperature ...
Phys.org / Microfluidic device simulates human tissue and offers an alternative to animal testing
Researchers at the Brazilian Center for Research in Energy and Materials (CNPEM) have developed microfluidic technology that can grow cells in three dimensions (3D). The goal is to conduct toxicity tests on new products by ...
Phys.org / Vapor-phase synthesis of MXenes could expand their technological applications
MXenes are two-dimensional nanomaterials first synthesized at Drexel University in 2011. They have been recognized by the International Union of Pure and Applied Chemistry as an emerging technology with "true potential to ...
Phys.org / Decoding the DNA switches behind gene regulation
Understanding gene regulation may be key to interpreting human disease genetics. Genes are regulated in part by stretches of DNA called enhancers, which define when, where and how strongly each gene is turned on. Mapping ...
Phys.org / Activated learning-and-memory protein forms growing molecular chains, imaging reveals
Researchers at the Nano Life Science Institute (WPI-NanoLSI) at Kanazawa University, Kyoto University, SOKENDAI and the National Institute for Physiological Sciences have revealed how CaMKIIα—a key brain protein involved ...
Phys.org / Moles' wide-armed posture reshapes how their shoulder bones carry loads
While the scapula is the primary bone supporting the body in terrestrial quadrupedal mammals, an analysis of internal bone structure in underground moles (family Talpidae) showed a more important role for the clavicle.
Phys.org / NASA spacecraft discovers a huge new crater on the moon
Scientists have discovered a crater on the moon that's bigger than the Roman Colosseum and is the result of a powerful impact two years ago that initially went undetected.
