Research conducted at the University of Campinas in Brazil was driven by observations of fluctuations in autoluminescence caused by seed germination in cycles regulated by gravitational tides.

The rhythms of activity in all biological organisms, both plants and animals, are closely linked to the gravitational tides created by the orbital mechanics of the Sun-Earth-Moon system. This truth has been somewhat neglected by scientific research but is foregrounded in a study by Cristiano de Mello Gallep at the University of Campinas (UNICAMP) in the state of São Paulo, Brazil, and Daniel Robert at the University of Bristol in the United Kingdom. An article on the study is published in the Journal of Experimental Botany.

“All matter on Earth, both live and inert, experiences the effects of the gravitational forces of the Sun and Moon expressed in the form of tides. The periodic oscillations exhibit two daily cycles and are modulated monthly and annually by the motions of these two celestial bodies. All organisms on the planet have evolved in this context. What we sought to show in the article is that gravitational tides are a perceptible and potent force that has always shaped the rhythmic activities of these organisms,” Gallep told Agência FAPESP.

The malware establishes initial access on targeted machines, then waits for additional code to execute.

A brand-new multiplatform malware, likely distributed via malicious npm packages, is spreading under the radar with Linux and Mac versions going fully undetected in VirusTotal, researchers warned.

The Windows version, according to a Tuesday writeup from Intezer, has only six detections as of this writing. These were uploaded to VirusTotal with the suffix “.ts,” which is used for TypeScript files.

Here’s a brain teaser for you: scientists are suggesting spacetime may be made out of individual “spacetime pixels,” instead of being smooth and continuous like it seems.

Rana Adhikari, a professor of physics at Caltech, suggested in a new press blurb that these pixels would be “so small that if you were to enlarge things so that it becomes the size of a grain of sand, then atoms would be as large as galaxies.”

Adhikari’s goal is to reconcile the conventional laws of physics, as determined by general relativity, with the more mysterious world of quantum physics.

UEI “Extreme Low-Power” chip for Bluetooth, voice remote controls with energy-harvesting in order to provide lifetime battery life.


Most people probably don’t mind changing batteries in remote controls every so often, but it contributes to e-waste especially if you’re not using rechargeable batteries, and I always find it’s pain as I don’t usually have stock, or don’t feel like waiting for several hours to recharge the batteries.

Universal Electronics Inc, or UEI for shorts, claims to have a solution with a family of QuickSet-certified chips using “Extreme Low-Power”, energy-harvesting and “high-performance technology” that would provide lifetime battery life to Bluetooth, voice remote controls. The main goal is “to help transition the world towards a more sustainable future, by reducing primary battery waste throughout the life of the product, which in turn reduces the cumulative CO2 footprint”.

The notion that some computational problems in math and computer science can be hard should come as no surprise. There is, in fact, an entire class of problems deemed impossible to solve algorithmically. Just below this class lie slightly “easier” problems that are less well-understood—and may be impossible, too.

David Gamarnik, professor of operations research at the MIT Sloan School of Management and the Institute for Data, Systems, and Society, is focusing his attention on the latter, less-studied category of problems, which are more relevant to the everyday world because they involve —an integral feature of natural systems. He and his colleagues have developed a potent tool for analyzing these problems called the overlap gap property (or OGP). Gamarnik described the new methodology in a recent paper in the Proceedings of the National Academy of Sciences.

Oculus Quests a re some of the best wireless VR headsets you can buy. But they can’t run high-end games like those found in the Steam Store. You can connect to a PC with a cable, but that’s inconvenient. Wirelessly streaming VR games required jumping through hoops with using developer mode and SideQuest. But with the $20 Virtual Desktop app, that’s not the case anymore.

Virtual Desktop always had the capability to wirelessly stream SteamVR games, in truth. You could install the streaming app on your PC and then your Oculus Quest VR headset, and as far as the app was concerned, you would have been good to go. But Oculus prevented the app from streaming VR games and limited it to just controlling your PC in a VR environment. It did so in the name of customer experience.
