The experiment was depicted by drawing a Sagnac interferometric fiber scheme in a magnifying inset, starting from a local position (Vienna, Austria) of the rotating Earth. Two indistinguishable photons impinge on a beam splitter cube, entanglement occurs between them and then they are coupled in the fiber interferometer. Credit: Marco Di Vita A team of … Read more
credit – Matthew Mulrennan, Colossal Last year, a group of scientists trying to capture images of a colossal squid, the largest invertebrate on Earth, in its natural habitat may have won their prize when one of their underwater cameras captured a young glass squid swimming by. Colossal squids are members of the glass squid family, … Read more
A TikToker has opened up about her theory on why we never really die, and it’s scaring people. You know that feeling after a night out where you go back to a friend’s house and sit there until the early hours, talking about random and slightly bizarre ideas or experiences so often that you feel … Read more
With more than 100 billion neurons and 200 billion cells, “the human brain,” Professor Kwanghun Chung explained to Interesting technique, “is one of the most complex systems in the universe.” With each subsequent development in thinking, the brain becomes more and more complex. Each neuron forms tens of thousands of unique functional connections with other … Read more
RS Puppis, one of Cepheid’s brightest variable stars, brightens and darkens rhythmically over a six-week cycle. Credit: NASA, ESA, Hubble Heritage Team (STScI/AURA)-Hubble/Europe Collaboration. hubblesite.org/contents/media/images/2013/51/3263-Image.html “Classical Cepheids” are a type of pulsating star that brightens and darkens rhythmically over time. These pulsations help astronomers measure vast distances in space, making Cepheids crucial “standard candles” that … Read more
A new science is emerging that promises to become the defining field of the 21st century. More than just a narrow specialization, it is not just a new field, but a new way of doing science – a new way of organizing intellectual domains and endeavors. Given its broad impact, it goes by several names, … Read more
A tardigrade is given a dose of CRISPR tools to change one of its genes, and those of the eggs it will produce. Credit: 2024 Tokiko Saigo et al. Some species of tardigrades are highly and unusually resilient to various extreme conditions that are fatal to most other life forms. The genetic basis for these … Read more
This map, superimposed on an image from NASA’s Mars Odyssey orbiter, shows Perseverance’s path between January 21 and June 11. White dots indicate where the rover stopped after completing a trip along the Neretva Vallis river channel. The light blue line shows the rover’s route within the canal.

In orange the location of the Barmaz site, looking south. It is located on the plain, at the foot of the Chablais massif, which rises to an altitude of 2,500 meters. The site is divided into two contemporary cemeteries called Barmaz I (dark blue) and Barmaz II (light blue) (Honegger and Desideri 2003, modified). Credit: … Read more
How it works: A proton (far left) from the Super Proton Synchrotron (SPS) accelerator at CERN collides with carbon nuclei (small gray spheres). This creates a shower of various elementary particles, including a large number of neutral pions (orange spheres). As the unstable neutral pions decay, they emit two high-energy gamma rays (yellow squiggly arrows). … Read more
