Phys.org / Major volcanic eruptions might be driven by gas dissolving back into magma
Understanding what triggers large volcanic eruptions is crucial for hazard assessment, but the exact mechanism driving these eruptions is still poorly understood. The prevailing theory is that volatile exsolution—gas coming ...
Phys.org / Japan's giant caldera volcano is refilling 7,300 years later
The magma reservoir of the largest volcanic eruption of the Holocene is refilling. This Kobe University insight on the Kikai caldera in Japan allows us to understand giant caldera volcanoes like Yellowstone or Toba more generally ...
Phys.org / Ancient DNA finds 15,800-year-old dogs in Anatolia, buried like humans
Evidence of some of the earliest dogs has been identified at two University of Liverpool/British Institute at Ankara archaeological excavation projects in central Anatolia, Turkey. Shedding new light on the development and ...
Phys.org / Bacteria invent another way to turn on genes
In their landmark 1961 paper on the lac operon, Nobel laureates François Jacob and Jacques Monod speculated that RNA might control gene activity in bacteria through base-pairing interactions. But once protein transcription ...
Phys.org / How lifetime stress drives abnormal behaviors in lab monkeys
It is not unusual for laboratory monkeys to engage in abnormal repetitive behaviors (ARBs), such as pacing and hair-plucking. Conventional thinking is that these actions are linked to recent stresses or current housing conditions. ...
Phys.org / Study explains Antarctic sea ice growth and sudden decline
A new Stanford University study has helped solve a mystery about dramatic swings in sea ice extent around Antarctica.
Phys.org / Liquids can fracture like solids—researchers discover the breaking point
In a development that could shift our basic understanding of fluid mechanics, researchers from Drexel University have reported that, given the right circumstances, it is possible to induce a simple liquid to fracture like ...
Phys.org / Implantable 'living pharmacy' produces multiple drugs inside the body
A multi-institutional team of scientists, co-led by Northwestern University, has taken a crucial step toward implantable "living pharmacies"—tiny devices containing engineered cells that continuously produce medicines inside ...
Phys.org / Earth's magnetic field creates a previously undetected pocket of protection from radiation on the moon
High-energy particles called galactic cosmic rays (GCRs) bombard unprotected objects in space, often causing damage. Earth, however, is protected by its magnetic field, which creates a protective shell around the planet that ...
Phys.org / Alaska analysis shows continued loss of Arctic landfast sea ice
Sea ice is sticking to Alaska's northern coast for less time each year, according to 27 years of data analyzed by University of Alaska Fairbanks scientists. Such landfast ice, which stays attached to the shoreline instead ...
Medical Xpress / How to contain avian flu H5N1 if human-to-human spread begins
At this point, avian flu H5N1 is thought to have very limited ability to transmit between humans, but a recent case in British Columbia with an unknown source of transmission has piqued the curiosity and concern of scientists, ...
Phys.org / Piezoelectric materials enable a new approach to searching for axions
Dark matter, a type of matter that does not emit, reflect or absorb light, is predicted to account for most of the matter in the universe. As it eludes common experimental techniques for studying ordinary matter, understanding ...
