Some quantum cryptographers want to find ways to keep messages secret even if the rules of quantum mechanics don’t hold. The recently rediscovered idea of quantum jamming complicates things.

There are a whole lot of people with “theories of everything” – theories which supposedly explain how the whole universe works. Most of the time, these theories fall very short of that goal. Causal Fermion Systems are an approach that actually seems promising… though it still has its flaws. Today I have a brief summary of what might be the most underreported theory of everything out there.

God is said to be all-powerful, all-knowing, all-good. But what is God’s private mental life like? Can we reach in to appreciate God as a supreme being? It may seem absurd, or arrogant, for finite human beings to strive to imagine what an infinite God is like and even what God may feel like privately and inside. But that is what we do.

Broken wrists are among the most common injuries in children, accounting for about half of children’s fractures. Severely displaced distal radial fractures, where the bones move out of place, are often routinely treated with surgery. However—unlike adults—children have a remarkable ability to straighten broken bones, in a process called remodeling. Researchers questioned whether a plaster cast would achieve the same long-term result without exposing children to the risks of an operation.
In a major U.K. trial led by researchers at the University of Oxford, they found that most children with a severely broken wrist can be treated without surgery. The findings, published in The Lancet, suggest that a nonsurgical, cast-first approach delivers similar long-term recovery while reducing the risks associated with surgery and costs.
Professor Matt Costa, senior author and Professor, Orthopedics Trauma Surgery at the Kadoorie Institute, University of Oxford, said, “These fractures can look very severe on an X-ray, which has traditionally led to surgery to straighten the bone. But because children’s bones are still growing, they have a remarkable capacity to heal. Until now, there has been limited high-quality evidence on whether surgery was always necessary.”
Research has shed important new light on the enemies-turned-allies that allow bacteria to exchange genes, including those linked to antimicrobial resistance (AMR). The insights, which expand our understanding of the major global health threat of AMR, came as John Innes Center researchers investigated the curious phenomena of gene transfer agents (GTAs).
These gene-carrying particles look like bacteriophages (viruses that infect bacteria), but they have been domesticated from ancient viruses and put to beneficial use under the control of the bacterial host cell.
Acting as couriers, they take up parcels of host bacterial DNA and deliver them to neighboring bacteria. This “selfless” sharing, known as horizontal gene transfer, can rapidly spread useful traits including genes that confer resistance to antibiotic drugs used to treat infections.
In the era of precision cosmology, research often means big science: large observatories, highly complex instruments, international collaborations and substantial funding. Yet even in such an advanced field, progress is still possible—including in the search for elusive dark matter—through more agile approaches, driven by small teams and young researchers, supported by institutions and a good dose of ingenuity.
In a paper titled “A New Limit for Axion Dark Matter with SPACE” published in the Journal of Cosmology and Astroparticle Physics, a group of then-undergraduate students from the University of Hamburg built a cavity detector to search for axions—among the most promising candidates for dark matter—and set new experimental limits on their properties.
The result was achieved with relatively limited resources, showing that even small-scale experiments can make a meaningful contribution to one of the most open challenges in modern physics.
New Curtin University-led research has used a radio telescope that spans Earth to snap images that measure the immense power of jets from black holes, confirming scientists’ theories of how black holes help shape the structure of the universe.
In a paper published in Nature Astronomy, researchers found the power of the jets in Cygnus X-1—a system comprised of the first confirmed black hole and a supergiant star—was equivalent to the power output of 10,000 suns.
To record the measurement, researchers used an array of linked-up telescopes separated by large distances to observe the black hole jets being buffeted by the winds of the star as the black hole moved around its orbit—much like how strong winds on Earth can push around water in a fountain.
