I have been off Facebook, and didn’t want to return, but I came across a lighthearted post in which technology “safeguarded a human life” we are experiencing alot of censorship where I live because youth have used technology in interesting ways to take on a Government.
A Samsung Galaxy A10s phone has emerged as the unlikely hero for taking a bullet for a protestor and earning the title of ‘lifesaver.’
Thermodynamic computing has the potential to revolutionize AI and machine learning by harnessing thermal fluctuations for faster, more efficient, and lower power computing systems Questions to inspire discussion What is the future revolution in computing? —The future revolution in computing is harnessing thermal fluctuations for physics-based computing systems.
Extreme Dormancy as a Way to Survive on Earth and Possibly also on Alien Planets (and May also be a Solution to Long-Term Space Travel) Posted on BigThink, with link at https://www.searchforlifeintheuniverse.com/post/extreme-dorm…en-planets
Cirrus Therapeutics, the University of Bristol, and London’s Global University Institute of Ophthalmology have discovered a new treatment for age-related macular degeneration (AMD), the leading cause of vision loss among older adults.
Featured on the cover of the journal Science Translational Medicine, this research reveals that boosting a specific protein, IRAK-M, in retinal cells could offer a new and highly effective therapy for AMD.
AMD can severely impact a person’s vision. Patients suffering from AMD often start with blurred vision or seeing a black dot in their central vision, which can ultimately expand to the point where there is no useful central vision. Currently, AMD affects approximately 200 million people worldwide, a number projected to rise to 288 million by 2040 with graying populations. The exact cause of AMD is complex and thought to involve a combination of aging, environmental, and lifestyle factors.
Exoplanets are common in our galaxy, and some even orbit in the so-called habitable zone of their star. NASA’s James Webb Space Telescope has been busy observing a few of these small, potentially habitable planets, and astronomers are now hard at work analyzing Webb data. We invite Drs. Knicole Colón and Christopher Stark, two Webb project scientists at NASA’s Goddard Space Flight Center, to tell us more about the challenges in studying these other worlds:
A potentially habitable planet is often defined as a planet similar in size to Earth that orbits in the ‘habitable zone’ of its star, a location where the planet could have a temperature where liquid water could exist on its surface. We currently know of around 30 planets that may be small, rocky planets like Earth and that orbit in the habitable zone. However, there is no guarantee that a planet that orbits in the habitable zone actually is habitable (it could support life), let alone inhabited (it currently supports life). At the time of writing, there is only one known habitable and inhabited planet—Earth.
The potentially habitable worlds Webb is observing are all transiting exoplanets, meaning their orbits are nearly edge-on so that they pass in front of their host stars. Webb takes advantage of this orientation to perform transmission spectroscopy when the planet passes in front of its star. This orientation allows us to examine the starlight filtered through the atmospheres of planets to learn about their chemical compositions.
With the rapid advancement of artificial intelligence, unmanned systems such as autonomous driving and embodied intelligence are continuously being promoted and applied in real-world scenarios, leading to a new wave of technological revolution and industrial transformation. Visual perception, a core means of information acquisition, plays a crucial role in these intelligent systems. However, achieving efficient, precise, and robust visual perception in dynamic, diverse, and unpredictable environments remains an open challenge.
In open-world scenarios, intelligent systems must not only process vast amounts of data but also handle various extreme events, such as sudden dangers, drastic light changes at tunnel entrances, and strong flash interference at night in driving scenarios.
Traditional visual sensing chips, constrained by the “power wall” and “bandwidth wall,” often face issues of distortion, failure, or high latency when dealing with these scenarios, severely impacting the stability and safety of the system.
Thermodynamic computing introduces a new, potentially more energy-efficient and probabilistic approach to computing, which could revolutionize the way we approach and understand computing Questions to inspire discussion What is thermodynamic computing? —Thermodynamic computing is a new approach to computing that aims to be more energy-efficient and probabilistic.
The probe also achieved stable neural recordings in rat brains for up to two years, showing excellent biocompatibility and long-term recording stability, state news agency Xinhua reported.
Cheng Heping, with the Chinese Academy of Sciences and director of the National Centre for Biomedical Imaging Science at Peking University, told Xinhua that the achievement provided a powerful tool for high-throughput simultaneous monitoring of activity in multiple brain regions, and for exploring the relationships between neural activity and behaviour.
