TIMELAPSE of Future Space Stations (Sci-fi Documentary)

Posted by in categories: drones, economics, education, food, space

What happens when humanity begins living in space, building larger space stations, and creating a purely space based economy. Space drones will deliver goods between stations, farming stations will grow food, and space hotels will host celestial events and viewing parties for eclipses and welcoming parties for spaceships returning from Mars.

This sci-fi documentary takes a look at the future of space stations and space technology, starting with the retiring of the International Space Station, and ending with the construction of the largest rotating ring world space station, with its own atmosphere and lakes that evaporate creating clouds and rain.

Something in space has been pulsing every 22 minutes for at least 35 years

Posted by in categories: energy, physics, space

Researchers reported the discovery of a new cosmic conundrum. The new object, GPM J1839-10, operates similarly to a pulsar, emitting frequent bursts of radio radiation. However, the physics that drives pulsars dictates that they would cease generating if they slowed too much, and practically every pulsar we know of blinks at least once every minute.

GPM J1839-10 has a pulse interval of 22 minutes. We don’t know what type of physics or things can power it.

Researchers use light to control ferrofluid droplet movements in water

Posted by in category: particle physics

A team of engineers at the Max Planck Institute for Intelligent Systems, the Chinese University of Hong Kong and the Gwangju Institute of Science and Technology has found that ferrofluidic drops in a tank of water can be forced to rise in desired ways using light. The study is published in the journal Science Advances.

Prior research has shown that ferrofluid droplets can be manipulated in water using a magnet. In this new study, the research team has shown that they can be manipulated by a light source as well.

Ferrofluid droplets are made by immersing magnetic particles in a drop of oil. Prior research has shown that they can be made to travel across a flat surface by dragging a magnet beneath them. If the droplets are heated, bubbles held inside of them expand, making the bubble bigger and more buoyant.

Massive 100-inch transparent screen set to enter production — scientists claim it will be 10 times cheaper than transparent OLEDs

Posted by in category: electronics

Researchers say the screen can work both indoors and outdoors, and can be adjusted to become more or less transparent depending on user needs.

Quantitative Justice: Using Data Science for Good

Posted by in categories: biotech/medical, mathematics, neuroscience, science

By Ariana Mendible

For the past several years, I have been closely involved with the Institute for the Quantitative Study of Inclusion, Diversity and Equity (QSIDE). This nonprofit organizes events and facilitates research in quantitative justice, the application of data and mathematical sciences to quantify, analyze and address social injustice. It uses the community-based participatory action research model to connect like-minded scholars, community partners, and activists together. Recently, QSIDE researchers met virtually in a Research Roundup to share our progress. Hearing all the incredible work that QSIDE has spawned and supported prompted me to reflect on the role that the group has played in my budding career and the ways in which the institute itself has grown since its founding in 2019.

Like many PhD candidates, my final year of graduate school was rife with burnout and uncertainty about post-graduation plans. Add to this mix a global pandemic, social isolation, and confinement to the same one-bedroom dwelling for the last year plus and you get a stew of anxiety. I was approaching my mental limit on the research I had been conducting, somewhere at the intersection of data science and fluid dynamics. While the problem I had been working on for my thesis was interesting, I was ready for a major change. I couldn’t picture myself in the usual post-graduate tracks: a post-doc at an R1 institution or working for a Big Tech company. These careers felt hyper-competitive, a turn-off during a period of significant burnout. I also couldn’t see their direct positive impact, which felt acutely important in this time of global social disarray.

New incompletely rifted microcontinent identified between Greenland and Canada

Posted by in category: climatology

Plate tectonics are the driving force behind Earth’s continental configurations, with the lithosphere (oceanic and continental crusts and upper mantle) moving due to convection processes occurring in the softer underlying asthenospheric mantle. Many earthquakes, volcanic eruptions and mountain formations are direct consequences of the movements of these globe-spanning plates, particularly at their margins.

New tractor beam technology could one day minimize biopsy trauma

Posted by in categories: particle physics, tractor beam

Researchers at TMOS, the ARC Center of Excellence for Transformative Meta-Optical Systems, have taken an important first step in the development of metasurface-enabled tractor beams—rays of light that can pull particles toward it, a concept that fictional tractor beams featured in science fiction are based on.

AI-powered optical detection to thwart counterfeit chips

Posted by in categories: finance, quantum physics, robotics/AI, security, surveillance

The semiconductor industry has grown into a $500 billion global market over the last 60 years. However, it is grappling with dual challenges: a profound shortage of new chips and a surge of counterfeit chips, introducing substantial risks of malfunction and unwanted surveillance. In particular, the latter inadvertently gives rise to a $75 billion counterfeit chip market that jeopardizes safety and security across multiple sectors dependent on semiconductor technologies, such as aviation, communications, quantum, artificial intelligence, and personal finance.

Results suggests titanium-48’s nuclear structure changes when observed at varying distances

Posted by in category: particle physics

The world around us is made up of particles invisible to the naked eye, but physicists continue to gain insights into this mysterious realm. Findings published in Physical Review C by Osaka Metropolitan University researchers show that the nuclear structure of an atom likely changes depending on the distance the protons and neutrons are from the center of the nucleus.
