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 / Newfound fungal nutrient-sensing mechanism could advance biofuels and disease control
Scientists have taken a step toward a better understanding of how fungi sense and respond to nutrients in the environment, which is critical for engineering fungi for green technologies and combating fungal pathogens and ...
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.
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 / How accurately can we measure the ocean's deepest point?
How deep is the deepest ocean—and how precisely can we actually measure it? A Japanese research team led by the National Institute of Polar Research (NIPR), SOKENDAI, the University of Tokyo and other Japanese institutions ...
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 / Laser shocks turn plastic into ultra-small, high-purity nanodiamonds
Nanodiamonds are tiny diamond particles that usually measure mere millionths of a millimeter. They are extremely hard, stable and heat-resistant and highly adaptable for various purposes in medicine, new materials, catalysis ...
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 / 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 / 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 / Is dark matter 'natural?' Physicist puts the question to the test
Dark matter is one of the oldest open problems in physics. It makes up most of the matter in the universe and shapes how galaxies form and move, yet no one has ever directly detected it. Physicists have proposed dozens of ...
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 ...
