Astronomy photo techniques can help tell if a photo is a Deepfake

 Scientists have found a feature of photos that can be added to a list of things to determine if a photo is authentic or a deepfake. Deepfakes are electronically created photos or videos, using AI, that are nearly impossible for untrained eyes to determine if the photo/video is of something real or made-up. There are countless examples online, and perhaps the most deepfaked person is former President Obama. 

Using techniques and information learned primarily from astronomers, and how they take and analyze photos of distant galaxies, it turns our that for photos of humans the key is to check out the eyes. In real photos, generally the reflections of light in the eyes should be the same. AI has not learned this correctly - YET - so presently one can check the colors and reflections of eyes, and that can help determine if it is a fake or not. 

This is especially important right now, heading into fall elections, when different individuals and groups are trying to smear candidates and get disinformation to go viral online. Deepfakes have become so easy to create that the average person looking at ads and content would likely not be able to tell the difference, making it SO challenging to determine what's real or not.

How the Illinois Cancer Center uses AI to help in its mission

 I want to occasionally provide students and teachers examples of evolving fields in STEM, and quite literally every field of STEM has been using and will only be increasing the use of advanced AIs in their research. This article gives an example of AI being used in all aspects of cancer research at the University of Illinois. 

From drug development to trying to do molecular detection of cancers, and simulating pathways of tumor development and how it spreads in the body, AI and computational research is revolutionizing many areas of STEM.

Research Program: Lumiere Research Scholar Program

A FYI that was received: 

Create an independent research paper. Work with top researchers 

The Lumiere Research Scholar Program helps high school students work one-on-one with a scholar on an independent research project. At the end of the program, you'll develop an independent research paper that you could use for college admissions or future studies. Our mentors are PhD scholars from top research universities such as Harvard, MIT,  Stanford, Yale, Duke and LSE. The program was founded by a Harvard & Oxford PhD who met as undergraduates at Harvard.  

 

The program is rigorous and fully virtual. We offer need based financial aid for students who qualify. You can find the application in the brochure! To learn more, you can reach out to our Head of Growth and Partnerships, Maya Novak-Herzog, at maya.novak-herzog@lumiere.education or go to lumiere-education.com.

The early bird deadline for application to the Fall cohort is July 30th, 2024.

Next level of AI 'thinking' and processing - CyberOctopus

  Using the way an octopus thinks about and navigates spatially, and also in time, researchers have created the next level of AI 'thinking' and processing information in its environment. This is episodic memory, and allows an AI to have better remembrances of past events it was involved in, learn from it, and have better thought out solutions to future problems based on those past events. It allows AI to be more animal-like rather than machine-like. Researchers have taken the leap from a sea slug brain, which is very simple, and made it more like an octopus brain...the evolution of this will ultimately, they think, to how a human brain operates, remembers, thinks things through, react to internal 'feelings', predict, and have creative, original thoughts. 

What are your thoughts about where AI is and where it will go? What should the ethics of creating and using AI's be? Who should make those decisions about AI? What are the consequences of more and more advanced AI in our human world, such as how will it change and replace humans jobs and careers? These are all vital questions we all should be thinking about, because AI is affecting most jobs and aspects of life already! 

Hurricane Beryl - a monster for this early in the hurricane season

For those interested in climate science and all that is related to it... 

The first major hurricane of the season, Hurricane Beryl, is hitting the Caribbean, and is now a category 5 (the strongest category) monster. This is a good article with an expert who says conditions for this year's season are unprecedented. In fact, this is the strongest storm on record this early in the season, due to the record high temperatures of the oceans and Gulf of Mexico. Remember, warm, moist air is the fuel for any storm, including hurricanes/cyclones, which is why the strengths of storms and amount of rain they release has been steadily rising the last couple decades.

Other Search Engines you may not be aware of...more than just Google!

 Here are some other search engines, most of which are useful for STEM research: 

www.refseek.com - Academic Resource Search. More than a billion sources: encyclopedia, monographies, magazines.

www.worldcat.org - a search for the contents of 20 thousand worldwide libraries. Find out where lies the nearest rare book you need.

https://link.springer.com - access to more than 10 million scientific documents: books, articles, research protocols.

www.bioline.org.br is a library of scientific bioscience journals published in developing countries.

http://repec.org - volunteers from 102 countries have collected almost 4 million publications on economics and related science.

www.science.gov is an American state search engine on 2200+ scientific sites. More than 200 million articles are indexed.

www.base-search.net is one of the most powerful researches on academic studies texts. More than 100 million scientific documents, 70% of them are free

Don't forget if you do use Google, it is best to use Google Scholar for academic work: https://scholar.google.com/ 

Using quantum entanglement to measure rotation of the earth

 A new technique has been devised that allows physicists to use quantum entanglement to measure the rotational rate of the earth. This is yet another example of the expanding set of experiments that are using quantum mechanical phenomena to measure all sorts of other phenomena, in addition to new quantum mechanical properties. There is a hope that experiments like this will lead to new insights of how quantum mechanics and gravity are related - the Holy Grail of physics is to construct a theory encompassing general relativity (gravity) with quantum mechanics and the Standard Model.  

This is an example of how experimental scientists can devise clever experiments with different phenomena present to expand the knowledge base of a field in order to hunt for new theoretical insights, coming from the observational data. I personally enjoy the back-and-forth interplay between theory and experiment in science!
