Texas University Researchers Just Made This Possible, "Quantum Light Source Advances Bio-Imaging Clarity"

1/n
Texas A&M University researchers have created a device capable of squeezing the quantum fluctuations of light down to a directed path and used it to enhance contrast imaging

2/n
This one-of-a-kind "flashlight" was built to increase the signal-to-noise ratio present in Brillouin microscopy spectroscopic measurements that visually record the mechanical properties of living cells and tissues

3/n
Brillouin microscopy is the fundamental limit of reduced-scale measurement imaging currently possible

4/n
It aims lasers at solid objects and measures the waves or signals of vibration made by the moving atoms and structures within the visibly unmoving material

5/n
Noise produced at this scale can severely obscure the signals received, creating muddied images that are hard to interpret

6/n
All laser spectroscopy systems suffer from the natural and technical signal distortions associated with laser light, so newer light sources are needed

7/n
The project was primarily supported by funding awarded to the Texas A&M Engineering Experiment Station from the Air Force Office of Scientific Research, with Yakovlev, Agarwal and Scully listed as principal investigators

8/n
“I love those types of projects where people tell you something will never work, and it works,” said Yakovlev. “I love challenges.”

9/n
So far, only the contrast of spectroscopy images has been improved, but Yakovlev and Agarwal are already working on Agarwal’s theory to enhance spatial resolution or the smallest details possible. 

10/n 
And if the task leads to creating another complex device that pushes the limits of current technology, the researchers are ready and willing to make that happen.

Solar Panels Will Become Mandatory On All New EU Buildings

A thread🧵 

1/n 
The European Union wants to accelerate the rollout of solar energy while also rebuilding Europe's solar manufacturing industry

2/n
Half of the EU's energy would come from renewable sources by 2030, more than double the current amount, according to the European Commission's plan, named RepowerEU.

3/n
The plan is part of the bloc's strategy to end its reliance on Russian fossil fuels, especially natural gas, by 2030.

4/n 
A shift towards solar energy

The EU aims to bring online over 320 GW of solar photovoltaic energy by 2025 and almost 600 GW by 2030

To reach the 2030 target, the EU would have to install, on average, 45 GW per year

According to some estimates, rooftop PV could provide almost 25% of the EU's electricity consumption

Installation can be deployed rapidly while also shielding consumers from high energy prices

5/n
The plan is expected to add 19 TWh of electricity after the first year of implementation and 58 TWh by 2025

In terms of saving energy, the European Commission wants to raise its current target for reducing energy consumption by 2030 via energy efficiency, from 9% to 13%.

It's also encouraging governments to implement policies to increase energy savings.

How To Build Brain-Inspired Neural Networks Based On Light

Death could be reversible, as scientists bring dead eyes back to life

A thread🧵 on futurism

1/7 
Scientists in the US proved that photosensitive neuron cells in the retina can still respond to light and communicate with each other up to five hours after death, sending signals "resembling those recorded from living subjects". 

Crucially these neurons form part of the central nervous system (CNS).

2/7 
Cells responded to different types of light

Lead author Dr Fatima Abbas, of the Moran Eye Centre at the University of Utah, said: 

"We were able to wake up photoreceptor cells in the human macula, which is the part of the retina responsible for our central vision and our ability to see fine detail and color.

3/7
In eyes obtained up to five hours after an organ donor’s death, these cells responded to bright light, coloured lights, and even very dim flashes of light."

4/7 
Breakthrough could speed up sight loss therapies

In early experiments, the team managed to revive the light-sensing cells, but struggled to get them to talk to each other

5/7
They designed a special transportation unit that could restore oxygenation and other nutrients to eyes as soon as they were removed from a donor.

6/7
The holder also includes electrodes which can be connected to both sides of the retina to monitor electrical signals.

7/7
“This opens up enormous opportunities for medical treatments for brain and eye disorders, including blindness. 

In addition, studies such as this at the intersection of life and death will enable science to explore what happens to the human mind, brain, and consciousness after death in a neutral and fairway.”

Your Next Teacher Will be a Machine: Why the Future of Education is Automation

A thread🧵 on futurism

1/ "The Algorithm and Social Platforms"

There is an educational revolution on the horizon

Artificial intelligence is getting faster, more accurate, and is unlocking entirely new ways to interact with content

We can already see the power of AI being used to serve billions of ads every day

How can we use similar technology to bring education into the age of the internet and expand the boundaries of what's possible?

2/ "Interactive Educational System"

What information should we teach students from the total sum of human knowledge to provide them with the best long-term educational outcome?

Riiid is a company focused on applying Artificial Intelligence to education and building these Interactive Educational Systems

Fully AI-driven, selecting each question individually to maximize the benefit for each student

Santa is an app that targets Korean students studying for the TOEIC Exam

3/ "Interesting things they are doing"

They employ a dropout prediction algorithm to predict when students will end their session and aim to create the highest overall outcome across users lifetime usage

Using dozens of data points, they can predict with more than 82% accuracy if a given student will get a given question correct

Questions are not grouped into topics or categories, questions are simply provided one after another in a style similar to TikTok

4/ "Education as a Technology"

Single-goal, AI-driven study apps like Riiid's Santa will become more prevalent in the coming years

Students will learn at hyper-speed compared to some ancient systems we use today

Student-teacher ratios have a very significant impact on student learning and on teacher sanity

By shifting large parts of the education process to automata, we can have both more teacher attention for each student and more students in the system

Teachers would no longer have to spend time on ineffective and menial activities such as grading 
or 
lecturing if those tasks are being done by AI

A platform could host space for skilled and passionate educators to monetize their abilities and provide value for a larger audience than previously possible

We could make education hugely profitable for quality teachers and grow an industry of entrepreneur-teachers

4/ "Go to YouTube, search for and watch something educational"

Something factual and interesting

When YouTube provides suggestions on the sidebar and after the video, select videos that are also high quality

Show the algorithm that you don't click on videos of low educational value

Over time, your home page will fill primarily with highly informative, well-made content

Complete Human Genome Sequenced for First Time In Major Breakthrough

New Space Plane Would Fly Directly Into Orbit From A Runway

Radian Aerospace has a plan to make a "holy grail" of spaceflight a reality

A thread🧵 

1. The startup secured funding for the Radian One, a first-of-its-kind space plane that flies into orbit after taking off horizontally from the ground.

2. No one has successfully launched a single-stage orbital space plane - yet. That’s the goal for Radian One, which is designed to accommodate a crew of five people and up to 5,000 pounds of cargo.

3. Space planes are vehicles that can fly horizontally in Earth's atmosphere, like airplanes, but can also enter space.

4. Radian One will then complete a low-g ascent into space under the power of its three onboard engines. After completing its mission, which could last up to five days, the space plane will land horizontally on a runway like an airplane.

5. They're reusable, like some rockets and spaceships, but unlike those crafts, space planes can land anywhere there's a standard commercial airplane runway - no need to target deserts, ships, landing pads, or oceans.

6. Radian aims to refurbish it and make the space plane ready to fly again within 48 hours of landing.

New Space Plane Would Fly Directly Into Orbit From A Runway

Artificial synapse created using capacitors

In this blossoming era of AI, efficient computational approaches to processing and storing large amounts of data are required.

A thread🧵 on futurism

1. Current computer designs have inherent performance limitations.

2. A new approach to in-memory computing proposes a new set up to create an artificial synapse that can both store and process data.

3. Capacitors record and store data as an electrical charge. 

In addition to requiring less power to operate, they also have the added advantage of being non-conductive, meaning that electric charges cannot easily enter capacitive synapses. 

This avoids what the researchers call sneaking leakage current, a chronic problem in artificial synaptic systems for years.

4. Without the problem of a sneaking leakage current, there is no need for an additional circuit component called a "selector" which minimizes leakage.

5. The capabilities of the new hafnium-capacitive synapse can be scaled up to 1000 times thinner than a human hair to achieve the same level of performance,

but it is still immature and needs to be optimized further and circuitry to continue to improve the performance of in-memory computing.

Artificial Synapse Created Using Capacitors

How to read and learn from books effectively and efficiently?

A thread🧵

With some techniques and tactics, we can trick our minds in a way that we can easily remember every important nugget and point of the book which we're reading.

So here’s :

The 3 Stage Learning Process:

1/ Pre-Reading
It is a step where you simply grasp the overview of book like reading front cover, back cover, preface, introduction and much more, to get mentally prepared and excited for the book. And this is done by Priming.

A psychological concept, Priming works by activating an association or representation in memory just before another stimulus or task is introduced. Our mind gets prepared consciously or subconsciously before reading the book.

2/ Highlighting

It is the step where you’ve to read the whole page and then highlight the important keywords and points to remember those. 

And when you need those insights, then you just have to recall the keywords to get them. This also helps in creating a summary for the specific page or the topic.

For example: Let's imagine, there’s a long story on the page related to Alexander and the lion. Then you should be highlighting like this: Alexander King, Injured Lion, Castle. By doing this, you can remember those.

3/ Note-Taking

• After reading the whole section, para, or short stuff. Instantly, You should’ve to take important points out of the section, para, or material and straight away write them to your notes.

• And what would be those important points? Obviously, after doing the highlighting step, those significant keywords and points will help you out there in your notes.

• And how should you write those notes effectively? Write it in such a way that you are explaining yourself by describing the key points and words in detail in the context of what you have learned from a section, paragraph, or material.

• After writing, you should re-evaluate the section you have read. If any changes are needed, correct them according to the material.

• While reevaluating, make sure to make a summary out of it, for better understanding and acknowledgment of the material in your mind.

And another method is

STIC Method

where,

S - Spacing
T - Testing
 I - Interleaving
C - Categorizing

1/ S - Spacing:

Spacing is known as Spaced Learning and which also the greatest solution of all time for The Forgetting Curve. 

Spaced Learning is the scientific and psychological concept where, In the order to retain knowledge and fully embed the learned material into our long-term memory, we have to periodically review the information. 

Moreover, research indicates that a minimum of three reviews of the material is necessary for obtaining the best results.

2/ T - Testing

This is the way where you have to test something about yourself, to evaluate what you have read/learned earlier. By memorizing and writing them down at the time of the exam, that material goes into the long-term memory of the brain.

3/ I - Interleaving

It is the method, where you’ve to learn any material by making groups of the items that exist in the material with the respect to their context or association.

For example - Good Morning, Good Afternoon, Good Evening, Good Night

4/ C - Categorizing

In this method, pick random words from anywhere and try to learn them by categories. Moreover, by making categories of those random words, you will remember them easily without any hassle.
