Phys.org / Plant breeding discovery could pave way for new crop species
One of the great mysteries in plant biology is how, given the clouds of pollen released by dozens of plant species all at the same time, an individual plant can recognize which particular species' pollen grains will induce ...
Phys.org / Theia and Earth were neighbors, new research suggests
About 4.5 billion years ago, the most momentous event in the history of Earth occurred: a huge celestial body called Theia collided with the young Earth. How the collision unfolded and what exactly happened afterward has ...
Phys.org / Bright squeezed vacuum reveals hidden quantum effects in strong-field physics
In a new study published in Nature Physics, researchers have demonstrated that quantum light, particularly bright squeezed vacuum (BSV), can drive strong-field photoemission at metal needle tips.
Phys.org / Climate change is now warming the deepest parts of the Arctic Ocean
While it is well known that climate change is heating the world's oceans, it was thought that the deep sea was safe from its effects—until now. Researchers have discovered that a rapidly warming part of the Atlantic is ...
Phys.org / Moss spores survive 9 months outside International Space Station
Mosses thrive in the most extreme environments on Earth, from the peaks of the Himalayas to the sands of Death Valley, the Antarctic tundra to the lava fields of active volcanoes. Inspired by moss's resilience, researchers ...
Phys.org / A new type of lion roar could help protect the iconic big cats
A new study has found African lions produce not one, but two distinct types of roars—a discovery set to transform wildlife monitoring and conservation efforts.
Phys.org / Mystery of how turtles read their magnetic map solved—they feel the magnetism
Loggerhead turtles are able to sense Earth's magnetic field in two ways, but it wasn't clear which sense the animals use to detect the magnetic field when navigating using the magnetic map they are born with. Now researchers ...
Phys.org / LHAASO conducts all-sky search for exploding primordial black holes
Primordial black holes (PBHs) are black holes theorized to have formed shortly after the Big Bang. Compared to black holes emerging from collapsing stars, PBHs could have very different masses, ranging from very small to ...
Phys.org / Dusty star-forming galaxy at high redshift discovered
An international team of astronomers reports the discovery of a new dusty star-forming galaxy at high redshift. The newfound galaxy, designated AC-2168, was detected using the Atacama Large Millimeter/submillimeter Array ...
Phys.org / Quantum calculations expose hidden chemistry of ice
When ultraviolet light hits ice—whether in Earth's polar regions or on distant planets—it triggers a cascade of chemical reactions that have puzzled scientists for decades.
Phys.org / The Suez Rift—once deemed inactive—is still drifting, study reveals
The tectonic plates under Africa and Asia are slowly drifting apart, as the Gulf of Suez that separates these two land masses continues to widen at a rate of about 0.26–0.55 millimeters per year.
Phys.org / Want to make new friends? Take a lesson from these birds
Making new friends has its challenges, even for birds. Researchers at the University of Cincinnati found that monk parakeets introduced to new birds will "test the waters" with potential friends to avoid increasingly dangerous ...
