MOND vs. Dark Matter: Research suggests that the rotation curves of galaxies remain flat indefinitely

by

The main technique Mistele used in his research, gravitational lensing, is a phenomenon predicted by Einstein’s general theory of relativity. As part of the research, Mistele plotted the so-called Tully-Fisher relationship on a map to highlight the empirical relationship between a galaxy’s visible mass and its rotation rate. In a discovery that challenges conventional understanding … Read more

Scientists pioneer new ultrasound technology that can scan the brain – Times of India

by

At the intersection of neuroscience and technology, a groundbreaking study has emerged where scientists have successfully mapped brain activity using ultrasound. This innovative approach, described in an article published May 29, 2024 in Science Translational Medicine, marks a significant advance in brain imaging techniques.The research team, led by Richard Andersen of the California Institute of … Read more

A satellite image shows an overview of the International Space Station with the Boeing Starliner spacecraft, June 7, 2024. Maxar Technologies | Via Reuters Boeing’s Starliner capsule “Calypso” will remain at the International Space Station twice as long as the mission was originally planned, NASA announced Friday. This developmental nature of the mission, known as … Read more

Quantum entangled photons respond to the Earth’s rotation

by

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

Mindmapper: MIT’s new technology shows entire hemispheres of the brain in 3D detail

by

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

Highly precise measurements challenge our understanding of Cepheids

by

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

Permanent genetic modifications to tardigrades help shed light on their astonishing resilience

by

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

NASA’s Perseverance fords an ancient river to achieve a scientific goal

by

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

Couple plasmas found in deep space can now be generated in the laboratory

by

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
