All.edu emails in the USA đŸ‡ș🇾 will WIN!Is the universe twice as old as we thought?Current estimates suggest that the Big Bang occurred 13.8 billion years ago. But today, we’re joined by Rajendra Gupta, a luminary in the field of cosmology who claims that the universe is actually 26.7 billion years old. I’ve invited him on the show so he can make a case for his claims!Professor Gupta is a theoretical physicist currently teaching astrophysics to senior undergraduate and graduate students at the University of Ottawa. His research focuses on astrophysics, cosmology, general relativity, the dynamics of the universe under evolutionary physical constants beyond the standard model, CMB, JWST, BAO, Big Bang nucleosynthesis, the large-scale structure and formation of galaxies, dark matter, and dark energy. To say I am thrilled to have him on the show for the second time would be an understatement. So, without further ado, let’s jump right in! Key Takeaways:

Tesla’s development of AI-powered self-driving cars has the potential to revolutionize transportation, disrupt labor, and create significant value in the market.

Questions to inspire discussion.

What is Tesla’s approach to AI-powered self-driving cars?
—Tesla’s approach involves convergence of AI hardware for cars and robots, with a focus on maximizing hardware and software interplay for real world AI products.

While seeking research internships last year, University of Washington graduate student Kate Glazko noticed recruiters posting online that they’d used OpenAI’s ChatGPT and other artificial intelligence tools to summarize resumes and rank candidates. Automated screening has been commonplace in hiring for decades. Yet Glazko, a doctoral student in the UW’s Paul G. Allen School of Computer Science & Engineering, studies how generative AI can replicate and amplify real-world biases—such as those against disabled people. How might such a system, she wondered, rank resumes that implied someone had a disability?

Scientists in Japan say they have reversed the signs of Alzheimer’s disease in lab mice by restoring the healthy function of synapses, critical parts of neurons that shoot chemical messages to other neurons.

The secret was developing a synthetic peptide, a small package of amino acids — a mini-protein, if you will — and injecting it up the nostrils of the mice, in an experiment they detailed in a study published in the journal Brain Research.

Needless to say, mice are very different from humans. But if the treatment successfully survives the gauntlet of clinical studies with human participants, it could potentially lead to a new treatment for Alzheimer’s disease, a tragic degenerative condition that burdens tens of millions of people around the world.

AI can turn wi-fi routers into cameras that can see in the dark and track living beings.


This video shows how AI turns WiFi routers into ‘cameras’ that can see people through walls.

With the help of AI, the researchers were able to detect the movement of human bodies in a room using Wi-Fi routers — even through walls.

Researchers are warning that geoengineering efforts to help cool temperatures in California could trigger heatwaves in Europe, a “scary” implication given the sheer lack of regulation controlling such measures across the globe.

As The Guardian reports, scientists have suggested spraying aerosols into clouds over the ocean to cool down the surface below, a practice called “marine cloud brightening.” As the name suggests, the idea is to brighten clouds to make them reflect more of the Sun’s radiation back into space.

Last month, a team of University of Washington researchers attempted to do just that in the San Francisco Bay using a machine that sprays tiny sea-salt particles, amid criticism from environmentalists. The experiment was later shut down by city officials, citing health concerns.

For more than 15 years, a group of scientists in Texas have been hard at work creating smaller and smaller devices to “see” through barriers using medium-frequency electromagnetic waves — and now, they seem closer than ever to cracking the code.

In an interview with Futurism, electrical engineering professor Kenneth O of the University of Texas explained that the tiny new imager chip he made with the help of his research team, which can detect the outlines of items through barriers like cardboard, was the result of repeat advances and breakthroughs in microprocessor technology over the better half of the last two decades.

“This is actually similar technology as what they’re using at the airport for security inspection,” O told us.
