Humanity getting lost in the MATRIOSHKA Brainđ€
Posted by Dan Breeden in categories: computing, finance, space travel
A Matrioshka Brain is a supermassive structure in space consisting of processors and connected to each other into a massive computer around a sun harnessing its energy completely. So far we havenât built one as we donât have the technology for it but when we do the question will be if people will be lost in the vast computing power of the Matrishka brain.

Scientists Have Engineered Parasitic Worms That Can Kill Cancer Cells
Posted by Josh Seeherman in categories: biotech/medical, materials
Nematodes, a specific sort of microscopic worm, have been proven by Osaka University researchers to be capable of killing cancer cells, according to Interesting Engineering and SciTechDaily.
The study titled âNematode surface functionalization with hydrogel sheaths tailored in situâ by Wildan Mubarok, Masaki Nakahata, Masaru Kojima and Shinji Sakai showed that Hydrogel-based âsheathsâ that can be further modified to transport useful cargo (cancer-killing substances) could be applied to these worms as a coating.

Scientists are searching for solutions after studies show pulse oximeters donât work as well for people of color

View insights.
Often when Dr. Thomas Valley sees a new patient in the intensive care unit at Michigan Medicine in Ann Arbor, he clamps a pulse oximeter on their finger â one of the many devices he uses to gauge their health and what course of care they might require, whether they are a child having seizures, a teenage car accident victim or an older person with Covid-19.
But recently, Valley, an assistant professor in the University of Michiganâs Division of Pulmonary and Critical Care, realized first-hand that the small device may yield less accurate oxygen readings in patients with dark skin.

The ultimate fate of a star shredded by a black hole
Posted by Shubham Ghosh Roy in categories: cosmology, materials
In 2019, astronomers observed the nearest example to date of a star that was shredded, or âspaghettified,â after approaching too close to a massive black hole.
That tidal disruption of a sun-like star by a black hole 1 million times more massive than itself took place 215 million light years from Earth. Luckily, this was the first such event bright enough that astronomers from the University of California, Berkeley, could study the optical light from the stellar death, specifically the lightâs polarization, to learn more about what happened after the star was torn apart.
Their observations on Oct. 8, 2019, suggest that a lot of the starâs material was blown away at high speedâup to 10,000 kilometers per secondâand formed a spherical cloud of gas that blocked most of the high-energy emissions produced as the black hole gobbled up the remainder of the star.

AI researchers tackle longstanding âdata heterogeneityâ problem for federated learning
Posted by Shubham Ghosh Roy in categories: biotech/medical, robotics/AI
Researchers from North Carolina State University have developed a new approach to federated learning that allows them to develop accurate artificial intelligence (AI) models more quickly and accurately. The work focuses on a longstanding problem in federated learning that occurs when there is significant heterogeneity in the various datasets being used to train the AI.
Federated learning is an AI training technique that allows AI systems to improve their performance by drawing on multiple sets of data without compromising the privacy of that data. For example, federated learning could be used to draw on privileged patient data from multiple hospitals in order to improve diagnostic AI tools, without the hospitals having access to data on each otherâs patients.
Federated learning is a form of machine learning involving multiple devices, called clients. The clients and a centralized server all start with a basic model designed to solve a specific problem. From that starting point, each of the clients then trains its local model using its own data, modifying the model to improve its performance. The clients then send these âupdatesâ to the centralized server. The centralized server draws on these updates to create a hybrid model, with the goal of having the hybrid model perform better than any of the clients on their own. The central server then sends this hybrid model back to each of the clients. This process is repeated until the systemâs performance has been optimized or reaches an agreed-upon level of accuracy.

The Future of Earth: 1000 Years From Now
Posted by Jose Ruben Rodriguez Fuentes in categories: climatology, sustainability
The Future of Earth: 1,000 Years From Now.
In the last 250 years, humans have drastically and irreversibly transformed the Earth. Greenhouse gases emitted by human industries have changed the planetâs climate, presenting the single greatest threat humanity has ever faced. If humans can cause such incredible damage to the Earth in 250 years, what will our planet look like in 1,000 years time?

A new approach to enhance multi-fingered robot hand manipulation
Posted by SaĂșl Morales RodriguĂ©z in category: robotics/AI
In recent years, roboticists have developed increasingly advanced robotic systems, many of which have artificial hands or robot hands with multiple fingers. To complete everyday tasks in both homes and public settings, robots should be able to use their âhandsâ to efficiently grasp and manipulate objects.
Enabling dexterous manipulation involving multiple fingers in robots, however, has so far proved challenging. This is primarily because it is an advanced skill that entails an adaptation to the shape, weight, and configuration of objects.
Researchers at UniversitÀt Hamburg have recently introduced a new approach to teach robots to grasp and manipulate objects using a multi-fingered robotic hand. This approach, introduced in IEEE Transactions on Neural Networks and Learning Systems, allows a robotic hand to learn from humans through teleoperation and adapt its manipulation strategies based on human hand postures and the data gathered when interacting with the environment.

New research uncovers key factor controlling ear development at early stages
Posted by SaĂșl Morales RodriguĂ©z in categories: biotech/medical, life extension
A new Kingâs-led study, published in the Proceedings of the National Academy of Sciences, has found that a single factor (a protein coding gene known as Sox8) can make non-ear cells adopt ear character during embryo development. The findings not only demonstrate how cell fate decisions are regulated in the embryo but may also inform reprogramming and regenerative strategies for the ear developmental malformations.
Responsible for the sense of hearing and balance, the inner ear is critically important for communication with the environment. In humans, developmental malformations of the ear have life-long consequences, while age-related hearing defects affect a large proportion of the population. Currently, there are no therapies that involve biological approachesâonly hearing aids or cochlear implants, as how the ear normally develops is not fully understood and many of the controlling factors are poorly characterized.
Researchers from the Faculty of Dentistry, Oral and Craniofacial Sciences at Kingâs, in collaboration with colleagues from the Francis Crick Institute, explored the earliest steps in ear development to determine what causes cells to become ear cells, and what makes them different from cells which form other sense organs.

Researchers remeasure gravitational constant
Posted by SaĂșl Morales RodriguĂ©z in category: futurism
The gravitational constant G determines the strength of gravityâthe force that makes apples fall to the ground or pulls the Earth in its orbit around the sun. It is part of Isaac Newtonâs law of universal gravitation, which he first formulated more than 300 years ago. The constant cannot be derived mathematically; it has to be determined through experiment.
Over the centuries, scientists have conducted numerous experiments to determine the value of G, but the scientific community isnât satisfied with the current figure. It is still less precise than the values of all the other fundamental natural constantsâfor example, the speed of light in a vacuum.
One reason gravity is extremely difficult to quantify is that it is a very weak force and cannot be isolated: when you measure the gravity between two bodies, you also measure the effect of all other bodies in the world.
