Phys.org / Quantum photonic chip integrates light-emitting molecules with single-mode waveguides
Photonic quantum processors, devices that can process information leveraging quantum mechanical effects and particles of light (photons), have shown promise for numerous applications, ranging from computations and communications ...
Phys.org / DNA transcription is a tightly choreographed event: How RNA polymerase II regulates the dance
Life's instructions are written in DNA, but it is the enzyme RNA polymerase II (Pol II) that reads the script, transcribing RNA in eukaryotic cells and eventually giving rise to proteins. Scientists know that Pol II must ...
Phys.org / Bisexual individuals experience greater loneliness than homosexuals and heterosexuals, study suggests
According to an EHU study, lack of social support leads to increased loneliness of bisexual people. The work by Garikoitz Azkona of the Psychobiology group explored the relationship between sexual orientation and loneliness. ...
Phys.org / North and Baltic seas show widespread contamination by MRI contrasting agents
A comprehensive study by the CritMET research group, led by Prof. Michael Bau, a geochemist at Constructor University in Bremen, provides evidence of widespread contamination of the North Sea and the Baltic Sea with MRI contrast ...
Phys.org / Scientists capture the crackling sounds of what they believe is lightning on Mars
Scientists have detected what they believe to be lightning on Mars by eavesdropping on the whirling wind recorded by NASA's Perseverance rover.
Phys.org / Drones: An ally in the sky to help save elephants
They say an elephant never forgets—and it turns out they can learn to adapt to drones. Once seen as a source of alarm, drones are now proving to be surprisingly elephant-friendly and a valuable research tool. Previously, ...
Phys.org / Russian cosmodrome damaged after joint launch with US
Russia's space launch site in Kazakhstan was damaged on Thursday after a Soyuz mission took off with Russian cosmonauts and US astronauts onboard, Moscow's space agency Roscosmos said.
Phys.org / RNA in action: Filming ribozyme self-assembly
RNA is a central biological macromolecule, now widely harnessed in medicine and nanotechnology. Like proteins, RNA function often depends on its precise three-dimensional structure. A recent study published in Nature Communications ...
Phys.org / Newly identified fossil fish from England's Jurassic Coast reveals insights into an extinct group
In a study by Dr. Martin Ebert and Dr. Steve Etches published in the Zoological Journal of the Linnean Society, the osteology and systematic position of a new species of fossil fish, Brachyichthys manselii comb. nov. was ...
Phys.org / Mystery foot belongs to ancient human relative: Scientists
Newly discovered fossils prove that a mysterious foot found in Ethiopia belongs to a little-known, recently named ancient human relative who lived alongside the species of the famous Lucy, scientists said Wednesday.
Medical Xpress / Reducing social media use for just a week can improve mental health
In a new study, published in JAMA Network Open, 295 participants report promising mental health benefits after reducing their social media usage for a week. The cohort consisted of young adults from the ages of 18 to 24—the ...
Phys.org / Survey raises estimate of African forest elephant numbers
DNA pulled from the dung of African forest elephants has given experts a more accurate—and higher—population estimate for the elusive animal, but the species remains critically endangered, a study showed Thursday.
