Phys.org / Global measures consistently underestimate food insecurity: 1 in 5 who suffer from hunger may go uncounted
International humanitarian aid organizations rely on analyses from the Integrated Food Security Phase Classification (IPC) system, a global partnership that monitors and classifies the severity of food insecurity to help ...
Phys.org / The monster hiding in plain sight: JWST reveals cosmic shapeshifter in the early universe
In a glimpse of the early universe, astronomers have observed a galaxy as it appeared just 800 million years after the Big Bang—a cosmic Jekyll and Hyde that looks like any other galaxy when viewed in visible and even ultraviolet ...
Phys.org / Earth's atmosphere may help support human life on the moon
The moon's surface may be more than just a dusty, barren landscape. Over billions of years, tiny particles from Earth's atmosphere have landed in the lunar soil, creating a possible source of life-sustaining substances for ...
Phys.org / A new species of tiny orange frog discovered in Brazil's cloud forests
Despite the vast numbers of animal species already identified, the natural world is still capable of springing a few surprises. Deep in the cloud forests of the Serra do Quiriri mountain range in the southern Brazilian Atlantic ...
Phys.org / All-optical modulation in silicon achieved via an electron avalanche process
Over the past decades, engineers have introduced numerous technologies that rely on light and its underlying characteristics. These include photonic and quantum systems that could advance imaging, communication and information ...
Phys.org / Astronomers examine nuclear star cluster of nearby galaxy Messier 74
By analyzing the data from the PHANGS-MUSE survey, an international team of astronomers has inspected a nuclear star cluster of the nearby large spiral galaxy Messier 74. The new study presented Dec. 3 on the arXiv pre-print ...
Phys.org / Ear piercings marked one of the earliest Maya rites of passage, research shows
In a recent study, Ph.D. candidate Yasmine Flynn-Arajdal studied iconographic representations of children in the Classic (ca. 250–950 AD) and Post-classic (ca. 950–1539 AD) imagery, as well as in ethnohistoric and ethnographic ...
Phys.org / Tiny optical modulator could enable giant future quantum computers
Researchers have made a major advance in quantum computing with a new device that is nearly 100 times smaller than the diameter of a human hair.
Phys.org / Polar bears may be adapting to survive warmer climates, says study
New research reveals a link between rising temperatures and changes in polar bear DNA, which may be helping them adapt and survive in increasingly challenging environments.
Phys.org / Dual substitution induces room-temperature ferromagnetism and negative thermal expansion in BiFeO₃
Using a dual-cation substitution approach, researchers at Science Tokyo introduced ferromagnetism into bismuth ferrite, a well-known and promising multiferroic material for next-generation memory technologies. By replacing ...
Phys.org / Parker Solar Probe spies solar wind 'U-turn'
Images captured by NASA's Parker Solar Probe as the spacecraft made its record-breaking closest approach to the sun in December 2024 have now revealed new details about how solar magnetic fields responsible for space weather ...
Phys.org / Chip-scale magnetometer uses light for high-precision magnetic sensing
Researchers have developed a precision magnetometer based on a special material that changes optical properties in response to a magnetic field. The device, which is integrated onto a chip, could benefit space missions, navigation ...
