Gravitational wave research has helped scientists learn more about a famous 2,000-year-old mechanical computer.
Summary: Advances in organoids and embryonic models raise questions about human individuality. A new study argues these models can reinforce, not weaken, the concept of human individuality when viewed through personhood and sentience frameworks.
Researchers emphasize that current technologies are far from achieving personhood in embryo models or organoids. The ethical focus should remain on the wellbeing of actual persons and sentient beings.
This single-center longitudinal cohort study has followed known carriers of PRNP pathogenic variants at risk for prion disease, individuals with a close relative who died of genetic prion disease but who have not undergone predictive genetic testing, and controls. All participants were asymptomatic at first visit and returned roughly annually. We determined PRNP genotypes, measured NfL and GFAP in plasma, and RT-QuIC, total PrP, NfL, T-tau, and beta-synuclein in CSF.
WASHINGTON — Turion Space, an Irvine, California-based startup, has secured a $1.9 million contract from SpaceWERX, the U.S. Space Force’s technology arm, to develop an autonomous spacecraft docking and maneuvering system. The contract aims to advance technologies for engaging uncooperative space objects and facilitating the deorbit of inactive satellites.
Ryan Westerdahl, Turion’s co-founder and CEO, said in an interview that the company is focusing on in-space mobility and non-Earth imaging. Turion launched its first satellite, Droid.001, a 32-kilogram spacecraft designed for space situational awareness, in June 2023. Data from this satellite is being integrated into the Space Force’s Unified Data Library.
Westerdahl revealed plans for a demonstration as early as 2026, featuring a Droid mothership hosting “micro-Droid” satellites equipped with the capturing device being developed under the SpaceWERX contract. The micro-Droid, partly funded by NASA, will use grapplers to capture debris objects.
The first #Quantum #Supercomputers are here! Quantum enabled supercomputing promises to shed light on new quantum algorithms, hardware innovations, and error mitigation schemes. Large collaborations in the field are kicking off between corporations and supercomputing centers. Companies like NVIDIA, IBM, IQM, QuEra, and others are some of the earliest to participate in these partnerships.

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.

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.
