The Sun has been intense the past week, and now solar flares are coming toward Earth

Posted by in category: space travel

There have been 24 coronal mass ejections in the past week alone.

As NASA’s Orion spacecraft prepares to fly by the Moon, sky gazers can expect another little treat in the skies as a minor geomagnetic storm is expected to hit the Earth, EarthSky.

Over the past week, our Sun has seen some intense activity. Usually, when activity on the Sun increases, the chances of a geomagnetic storm on Earth also increase. Geomagnetic storms carry risks to infrastructure and communications on the planet. However, in the past week, our planet has been a bit lucky it wasn’t in the line of fire.

A prediction model claims Brazil will be the champion of World Cup 2022

Posted by in category: futurism

We will see on December 18 whether the prediction program is working or not.

The 2022 FIFA World Cup, also known as Qatar 2022, started yesterday, and its excitement has echoed worldwide. It is a matter of curiosity which nation will be the champion in this big event.

Algae-Powered Soft Devices Glow in the Dark When Squished or Stretched

Posted by in categories: energy, food

The devices are so sensitive that even a soft tap is enough to make them glow. The researchers also made the devices glow by vibrating them, drawing on their surfaces, and blowing air on them to make them bend and sway—which shows that they could potentially be used to harvest airflow to produce light. The researchers also inserted small magnets inside the devices so that they can be magnetically steered, glowing as they move and contort.

The devices can be recharged with light. The dinoflagellates are photosynthetic, meaning they use sunlight to produce food and energy. Shining light on the devices during the day gives them the juice they need to glow during the night.

A Life in Games

Posted by in categories: computing, mathematics

Gnawing on his left index finger with his chipped old British teeth, temporal veins bulging and brow pensively squinched beneath the day-before-yesterday’s hair, the mathematician John Horton Conway unapologetically whiles away his hours tinkering and thinkering — which is to say he’s ruminating, although he will insist he’s doing nothing, being lazy, playing games.

Based at Princeton University, though he found fame at Cambridge (as a student and professor from 1957 to 1987), Conway, 77, claims never to have worked a day in his life. Instead, he purports to have frittered away reams and reams of time playing. Yet he is Princeton’s John von Neumann Professor in Applied and Computational Mathematics (now emeritus). He’s a fellow of the Royal Society. And he is roundly praised as a genius. “The word ‘genius’ gets misused an awful lot,” said Persi Diaconis, a mathematician at Stanford University. “John Conway is a genius. And the thing about John is he’ll think about anything.… He has a real sense of whimsy. You can’t put him in a mathematical box.”

Study Reveals Brain’s Finely Tuned System of Energy Supply

Posted by in categories: biotech/medical, neuroscience

The experiments demonstrated that the blood cells can sense when the environment outside the capillaries is low in oxygen – which occurs when neurons take up more oxygen to generate energy – and respond by rushing to deliver more. They also observed that this response if very rapid, occurring less than a second after oxygen is pulled out of the surrounding tissue.

This phenomenon is unique to the capillaries because of their size. The thin walls of the microvessels mean that the oxygen levels in adjacent brain tissue are mirrored within the capillaries, which can signal to red blood cells to spring into action.

The findings could have implications for a number of neurological disorders, including Alzheimer’s disease. It has been observed that blood flow in the brains of people with the disorder is impaired when compared to healthy brains. The difficulty in delivering the oxygen necessary for neuronal activity may help explain the cognitive difficulties that are one of the hallmarks of the disease.

The Extended Mind | Andy Clark

Posted by in categories: biological, cyborgs, mobile phones, robotics/AI

https://www.youtube.com/watch?v=5eVyphsl0x0

Where does the mind end and the world begin? Is the mind locked inside its skull, sealed in with skin, or does it expand outward, merging with things and places and other minds that it thinks with? What if there are objects outside—a pen and paper, a phone—that serve the same function as parts of the brain, enabling it to calculate or remember?

In their famous 1998 paper “The Extended Mind,” philosophers Andy Clark and David J. Chalmers posed those questions and answered them provocatively: cognitive processes “ain’t all in the head.” The environment has an active role in driving cognition; cognition is sometimes made up of neural, bodily, and environmental processes.

The strange, brain-like memory of vanadium dioxide glass

Posted by in categories: biological, neuroscience

Vanadium dioxide is a strange material that “remembers” information and when it was stored. This is akin to biological memory.
