Phys.org / Cells use Morse code-like rhythms to coordinate growth
Cells experience many different types of stress, such as starvation or stress caused by too much salt or too high a temperature. Insulin signals respond to such stress signals by sending the protein DAF-16 into the cell nucleus ...
Phys.org / Deep Sulawesi cave dig could reveal overlap between extinct humans and us
Could Homo sapiens and an archaic and now-extinct species of early human have lived alongside each other on the Indonesian island of Sulawesi more than 65,000 years ago?
Phys.org / Astrophysicists map how many ghost particles all the Milky Way's stars send towards Earth
They're called ghost particles for a reason. They're everywhere—trillions of them constantly stream through everything: our bodies, our planet, even the entire cosmos. These so-called neutrinos are elementary particles ...
Phys.org / Behind nature's blueprints: Physicists create 'theoretical rulebook' of self-assembly
Inspired by biological systems, materials scientists have long sought to harness self-assembly to build nanomaterials. The challenge: the process seemed random and notoriously difficult to predict.
Phys.org / Some dogs can learn new words by eavesdropping on their owners
"Honey, will you take Luna to the P-A-R-K?" Both parents and dog owners know that some words should not be spoken, but only spelled, to prevent small ears from eavesdropping on the conversation. At the age of 1.5 years, toddlers ...
Phys.org / The electrifying science behind Martian dust
Mars, often depicted as a barren red planet, is far from lifeless. With its thin atmosphere and dusty surface, it is an energetic and electrically charged environment where dust storms and dust devils continually reshape ...
Phys.org / Tree bark microbes also clean the air by removing greenhouse and toxic gases
Australian researchers have discovered a hidden climate superpower of trees. Their bark harbors trillions of microbes that help scrub the air of greenhouse and toxic gases.
Phys.org / Earliest known barred spiral galaxy spotted just 2 billion years after Big Bang
Research led by Daniel Ivanov, a physics and astronomy graduate student in the Kenneth P. Dietrich School of Arts and Sciences at Pitt, uncovered a contender for one of the earliest observed spiral galaxies containing a stellar ...
Phys.org / Sensor lights up to reveal scopolamine, a common substance used for sexual assault
A team from the Universitat Politècnica de València (UPV) has led the development of a new sensor capable of quickly and easily detecting scopolamine, one of the substances most commonly used in crimes of chemical submission, ...
Phys.org / How did these strange, ancient organisms turn into such remarkable fossils?
In Earth's fossil record, soft-bodied organisms like jellyfish rarely stand the test of time. What's more, it's hard for any animal to get preserved with exceptional detail in sandstones, which are made of large grains, are ...
Phys.org / A new way to view shockwaves could boost fusion research
At the heart of our sun, fusion is unfolding. As hydrogen atoms merge to form helium, they emit energy, producing the heat and light that reach us here on Earth. Inspired by our nearby star, researchers want to create fusion ...
Phys.org / Conserved genome regulatory elements found in both vertebrates and echinoderms
The conservation of genome regulatory elements over long periods of evolution is not limited to vertebrates, as previously thought, but also in echinoderms (invertebrates). This is one of the most notable conclusions of a ...
