Phys.org / The enzyme that doesn't act like one: NUDT5 controls DNA building block production through structure, not catalysis
Inside every cell, a finely tuned metabolic network determines when to build, recycle, or stop producing essential molecules. A central part of this network is folate metabolism, a process that provides vital chemical units ...
Phys.org / Populist parties choose divisive issues on purpose, researchers say
Populists use controversial issues to a far greater extent than other issues to promote their political messages. This is deliberate.
Phys.org / Illegal shark fin trade persists despite protections
Despite more than a decade of international efforts to curb the trade of threatened shark species, new research led by FIU marine biologist Diego Cardeñosa and Demian Chapman, director of the Shark and Rays Conservation ...
Phys.org / ESA's HydroGNSS Scout satellites ready for launch
After arriving at the California launch site at the end of September, the two HydroGNSS satellites have been carefully prepared for liftoff, scheduled this month.
Medical Xpress / Meditation retreat rapidly reprograms body and mind, brain monitoring reveals
Researchers at the University of California San Diego have found that an intensive retreat combining multiple mind-body techniques, including meditation and healing practices, produced rapid and wide-ranging changes in brain ...
Phys.org / NASA's ESCAPADE mission to Mars—twin satellites dubbed Blue and Gold will launch in early November
The first dual-satellite mission to another planet, NASA's ESCAPADE (Escape and Plasma Acceleration and Dynamics Explorers), is scheduled for launch no earlier than Sunday, Nov. 9, from Cape Canaveral, Florida. The two identical ...
Tech Xplore / Fake or the real thing? How AI can make it harder to trust the pictures we see
A new study has revealed that artificial intelligence can now generate images of real people that are virtually impossible to tell apart from genuine photographs.
Phys.org / Entanglement swapping using sum-frequency generation between single photons demonstrated for first time
The National Institute of Information and Communications Technology (NICT) has successfully demonstrated entanglement swapping (one of the key quantum communication protocols) using sum-frequency generation (SFG) between ...
Phys.org / Creating better tools to read our DNA's hidden instructions
DNA isn't just a long string of genetic code, but an intricate 3D structure folded inside each cell. That means the tools used to study DNA need to be just as sophisticated—able to read not only the code itself, but how ...
Phys.org / Digital map increases Roman Empire road network by 100,000 kilometers
A new high resolution digital dataset and map—named Itiner-e—of roads throughout the Roman Empire around the year 150 CE is presented in research published in Scientific Data. The findings increase the known length of ...
Medical Xpress / Low-dose THC may reduce side effects of HIV treatment
Long-term, low doses of THC mitigate many harmful side effects and inflammation caused by HIV and antiretroviral therapy (ART), according to new research from Texas Biomedical Research Institute.
Phys.org / Compact laser system shows 80% efficiency for ultrashort light pulses is possible
Lasers that emit extremely short light pulses are highly precise and are used in manufacturing, medical applications, and research. The problem: efficient short-pulse lasers require a lot of space and are expensive.
