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 / 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 / What ancient Mars rocks reveal about its buried carbonate stores
Carbonate minerals are among the best records of past liquid water on Mars: They form when water carrying dissolved carbon dioxide reacts with rock, and their composition reflects the chemistry of both. Yet Mars has surprisingly ...
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 / Diamond quantum sensors can detect heart magnetism at room temperature without skin contact
Physicists at Johannes Gutenberg University Mainz (JGU) have developed a technology that uses quantum sensors to measure biomagnetic signals, such as heart activity. Researchers from the DIAQNOS (DIAmond-based Quantum Sensing ...
Phys.org / Ubiquitin marks abnormal glycogen for destruction to protect the brain, study finds
Researchers at the University of Cambridge and the MRC Laboratory of Molecular Biology have discovered a previously unknown cellular defense system that protects the brain from abnormal glycogen accumulation, which is linked ...
Phys.org / European ash pangenome could help researchers breed a generation of trees resistant to ash dieback
In a study published in the journal Nature Communications, researchers from the Royal Botanic Gardens, Kew, Forest Research and collaborating organizations present the first-ever European ash (Fraxinus excelsior) pangenome, ...
Phys.org / How a simple game of 20 questions could help make AI fit for the future
Artificial intelligence programs used to classify images could be trained much more cheaply using a surprisingly simple method inspired by the childhood game of 20 Questions, according to new research posted to the arXiv ...
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 / Chemists overturn 40-year assumption about a key class of superconductors
Scientists at Warwick have shown that a material treated for 40 years as a uniform, textbook superconductor is in fact a patchwork of different crystal structures throughout its bulk, using an advanced 3D imaging technique ...
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 / Sixteen new fungus species found hiding in Thailand's flowers
Researchers have discovered 16 new species of fungus living unnoticed inside garden flowers and wildflowers across northern Thailand, more than quintupling the number of such fungi known to occur in the country. The findings ...
