Once dismissed as a new age fad, lucid dreaming has gained attention as a possible performance enhancer and therapeutic tool.

The Science of Sleep: How to Get Better Sleep Every Night
We all know the feeling of waking up groggy and exhausted, struggling to find the energy to tackle the day ahead. The key to breaking free from this cycle lies in understanding the science of sleep and adopting evidence-based strategies to enhance its quality. So, let’s explore the stages of sleeping and the role of circadian rhythms in regulating our sleep-wake cycles to transform your habits and embark on the journey to obtain better sleep every night!
Get Better Sleep Every Night: Understand the Science
Sleep is far from being a passive state of unconsciousness. On the contrary, it’s a complex process that plays a vital role in our physical and mental well-being. To improve our sleep quality, we must learn more about its stages.
Lab-grown meat: the science of turning cells into steaks and nuggets
“It tastes like chicken.” That’s a common review of UPSIDE Foods’ new trial product. Perhaps that’s not surprising: it is, after all, chicken — at the cellular level. But the fillets are not from a slaughterhouse. They are grown in bioreactors in an urban factory in California.
Alittle over a decade ago, only a handful of researchers were investigating the potential of laboratory-made meat. The world’s first cultured beef burger, which reportedly cost US$325,000, was made by Maastricht University biomedical engineer Mark Post, who ate it at a press conference in 2013. Such products are now much closer to market: more than 150 companies around the world are working on cultured meat (from ground beef to steaks, chicken, pork and fish), milk or related ‘cellular agriculture’ products, including leather.
Companies making cultured meat are attracting billions of dollars of investment. Here are their biggest challenges.
Eric Schmidt: This is how AI will transform the way science gets done
Usual weather prediction systems have the capacity to generate around 50 predictions for the week ahead. FourCastNet can instead predict thousands of possibilities, accurately capturing the risk of rare but deadly disasters and thereby giving vulnerable populations valuable time to prepare and evacuate.
The hoped-for revolution in climate modeling is just the beginning. With the advent of AI, science is about to become much more exciting—and in some ways unrecognizable. The reverberations of this shift will be felt far outside the lab; they will affect us all.

Accelerating Effective Treatments To Prevent And Reverse Human Age-Related Disease — Dr. Aubrey de Grey, Ph.D. — President & Chief Science Officer, Longevity Escape Velocity Foundation (LEVF)
Dr. Aubrey de Grey, Ph.D., is President & Chief Science Officer of the Longevity Escape Velocity (LEV) Foundation (https://www.levf.org/), an organization focused on proactively identifying and addressing the most challenging obstacles on the path to the widespread availability of genuinely effective treatments to prevent and reverse human age-related disease.
Dr. de Grey is internationally recognized as a visionary biomedical gerontologist who devised the Strategies for Engineered Negligible Senescence: a comprehensive set of methods to rejuvenate the human body, thereby preventing age-related ill health and mortality. He has co-founded multiple non-profit organizations – including Methuselah Foundation, SENS Research Foundation, and now LEV Foundation – to specifically enable and accelerate its development and clinical translation.
Dr. de Grey received his BA in Computer Science and Ph.D. in Biology from the University of Cambridge in 1985 and 2000, respectively. He is the author of The Mitochondrial Free Radical Theory of Aging (1999), Ending Aging (2007), and a large number of academic papers.
Dr. de Grey is a Fellow of both the Gerontological Society of America and the American Aging Association, and sits on the advisory boards of numerous scientific journals and research organizations. He is a prolific speaker who regularly presents at conferences and events world-wide.
“I’m really into planetary defence”: Meet the 13-year-old whose science project could protect Earth from asteroids
Do you ever mesh your other hobbies with the space stuff? Yes. I once turned the results of one of my experiments into a musical. In 2020, during the lockdowns, I put a scientific instrument on my balcony to measure light, sound and pollution before and after the pandemic. I ended up with several graphs and thought, Why not turn these into a musical? So, me and my brother got several musical instruments and played notes according to how high or low each point on the graph was. We actually submitted that to the NASA SpaceApps COVID-19 Challenge and became one of the top six global winners.
Do you think you’ll study space science at university when you’re older? I think so. Either aerospace or astrophysics, or maybe both.
Any other cool projects in the pipeline? Not right now, but I’m getting ready to go to Belgium this September, to represent Canada in the EU Contest for Young Scientists, which is an international science competition. I’ll be able to showcase this project there. But before then, I need to make a 10-page project report with figures, summaries and scientific documents. And I’ll need a poster!
Boulder Bonanza! Science and Sampling Attempts at the Onahu Outcrop on Mars
Mars Perseverance Rover struggled to collect samples from a crumbly, potentially conglomerate rock at the Onahu outcrop, before exploring another location, Stone Man Pass. Meanwhile, the rover continues to analyze nearby boulders and progress towards Jezero’s inner rim, home to the anticipated carbonate-rich “margin unit,” in pursuit of insights into Mars’ geological history.
Recently on Mars, Perseverance wrestled with sampling a crumbly rock and continued the mission’s boulder-bonanza!
Perseverance spent 3 weeks exploring the Onahu outcrop, after having previously performed an abrasion named Ouzel Falls. From this abrasion, scientists saw that the rock is most likely a conglomerate worth sampling, but was also likely to be crumbly.
Harvard’s new computer science teacher is a chatbot
Harvard University plans to use an AI chatbot similar to ChatGPT as an instructor on its flagship coding course.
Students enrolled on the Computer Science 50: Introduction to Computer Science (CS50) programme will be encouraged to use the artificial intelligence tool when classes begin in September.
The AI teacher will likely be based on OpenAI’s GPT 3.5 or GPT 4 models, according to course instructors.
