Meta Just Made It Easier for Small Developers to Get Apps Into the Main Quest Store

Posted by in category: computing

Quest users searching the Store will now be able to more easily find games published through its early access distribution channel, App Lab, which previously weren’t visible, effectively giving smaller studios a more level playing field.

Meta is making its operating system and app store available on third-party VR headsets sometime soon, and one of the bigger changes coming to the platform is the blurring of the barrier between the Main Store and App Lab.

Besides offering a way for studios to publish their titles in early access, App Lab also lets any developer who meets basic technical and content requirements ship software on the platform, effectively making it open to studios of any size.

The Stem Cell Podcast

Posted by in categories: biotech/medical, genetics, life extension

In episode 267 of the Stem Cell Podcast, we chat with Dr. Shankar Srinivas, a Professor of Developmental Biology in the Department of Physiology Anatomy and Genetics based in the Institute for Developmental and Regenerative Medicine at the University of Oxford. He is also a Zeitlyn Fellow and Tutor in Medicine at Jesus College. Using mouse and human embryos as model systems, his group looks at the control of patterning and morphogenesis during the establishment of the anterior-posterior axis, gastrulation, and early cardiogenesis. He discusses how tissues respond to forces during early development, characterizing cardiac progenitors, and training internationally.

Scientists raise minimum magnetic field of a single measurement to sub-femtotesla level

Posted by in category: quantum physics

A research team has, for the first time, realized the quantum amplification of an extremely weak magnetic field by using dark spin, with the magnetic field magnification exceeding a factor of 5,000 and the single magnetic field measurement accuracy reaching 0.1fT level. The study is published in Proceedings of the National Academy of Sciences.

Using a Floquet quantum detector to constrain axion-like dark matter

Posted by in categories: cosmology, particle physics, quantum physics

A team of researchers affiliated with several institutions in Israel has used a Floquet quantum detector to constrain axion-like dark matter, hoping to reduce its parameter space. In their paper published in the journal Science Advances, the group describes their approach to constraining the theoretical dark matter particle as a means to learning more about its properties.

Despite several years of effort by physicists around the world, remains a mystery. Most physicists agree that it exists, but thus far, no one has been able to prove it. One promising theory involving the existence of interacting has begun to lose its luster, and some teams are looking for something else. In this new effort, the researchers seek axions, or axion-like particles. Such dark matter particles have been theorized to be zero-spin and able to possess any number of combinations of mass and interaction strength. The team sought to constrain the features of axion-like particles to reduce the number of possibilities of their existence and thereby increase the chances of proving their existence.

The researchers used a shielded glass cell filled with rubidium-85 and xenon-129 atoms. They fired two lasers at the cell—one to polarize the rubidium atoms’ electronic spin and the xenon’s nuclear spin, and the other to measure spin changes. The experiment was based on the idea that the oscillating field of the axions would impact on the xenon’s spin when they are close in proximity. The researchers then applied a to the cell as a means of blocking the spin of the xenon to within a narrow range of frequencies, allowing them to scan the possible oscillation frequencies that correspond to the range of the axion-like particles. Under this scenario, the Floquet field is theorized to have a frequency roughly equal to the difference between the (NMR) and the electron paramagnetic resonance, and their experiment closes that gap.
