Mind-Blowing: Two People Just Had a ‘Conversation’ While Dreaming

 A California-based neurotech start-up, REMspace, claims to have achieved a groundbreaking milestone by facilitating the first-ever communication between two people while they were dreaming. This “historic milestone,” as REMspace calls it, aims to unlock new dimensions of communication, with enormous potential applications.

REMspace, a company in the San Francisco Bay Area focused on sleep enhancement and lucid dreaming, shared that two participants managed to exchange a simple message within their dreams on September 24. Using REMspace’s innovative “apparatus,” the company monitored participants’ sleep stages remotely. The device tracked brain waves, blood oxygen levels, heart rate, and breathing during sleep, and transmitted data via WiFi to REMspace’s server. Once the server detected that the first participant entered a lucid dream state, it transmitted a randomly generated word to him through earbuds, which he reportedly heard and remembered in his dream. Later, when the second participant entered a lucid dream, the word was transmitted to them as well. Upon waking, the second participant repeated the word, marking what REMspace claims is the first “chat” ever exchanged within dreams.

This feat has significant implications for the field of lucid dreaming. Lucid dreaming, the ability to consciously control one’s actions while dreaming, typically occurs during the vivid REM sleep stage. It allows individuals to interact with their dream environment in a self-directed manner, potentially enabling new forms of mental and emotional exploration.

Following the initial success, REMspace repeated this experiment on October 8, again facilitating dream-based communication between two participants. REMspace’s CEO, Michael Raduga, envisions a future where dream-based communication could become mainstream. “Yesterday, communicating in dreams seemed like science fiction,” he stated. “Tomorrow, it will be so common we won’t be able to imagine our lives without it.” Raduga foresees an emerging industry based on REM sleep and lucid dreaming, with far-reaching possibilities.

The company has not yet revealed the specific technology behind its equipment, but it has submitted a research paper for scientific review, expecting publication within two to six months. So far, there has been no external scientific validation or replication of REMspace’s findings. Raduga anticipates that technologies like REMspace’s device could become as ubiquitous as smartphones, enhancing life in ways we may only just be beginning to understand.

REMspace is now seeking more candidates experienced in lucid dreaming for further trials. Raduga’s passion for the field extends to extreme lengths, exemplified by a dramatic experiment he undertook last year: he drilled a microchip into his own skull in an attempt to control his dreams. Though risky, Raduga’s dedication reflects the broader drive of REMspace to push the boundaries of communication and mental exploration in the realm of dreams.

Over the summer, Sirish worked closely with his mentor, Aditya Banerji, a Senior Research Engineer at 3M, who helped him transform Pestiscand from concept to prototype. Second and third places were awarded to Minula Weerasekera from Oregon, for a unique energy storage solution, and William Tan from New York, for an AI-powered artificial reef that supports marine life growth, with each student receiving a $2,000 prize.

Now in its 17th year, the 3M Young Scientist Challenge continues to inspire youth to develop real-world solutions using STEM. Past winners have gone on to file patents, give TED Talks, and appear on prestigious lists like Forbes’ 30 Under 30. By providing resources and mentorship, 3M and Discovery Education encourage the next generation to turn their innovative ideas into impactful, real-world solutions.

Ancient DNA Powers Pregnancy: A Surprising Twist

 Pregnancy is a miraculous process, involving complex biological changes to support a growing baby. One of the most significant changes is an increase in blood production. While hormones play a role in this process, scientists have been puzzled by the exact mechanisms behind it.

A New Discovery

A recent study has uncovered a surprising secret: ancient, virus-like DNA sequences, known as transposons or "jumping genes," are activated during pregnancy. These genetic elements, once thought to be useless "junk DNA," are now being recognized for their potential benefits.

How Do Transposons Help?

When activated, these transposons trigger an immune response, similar to how the body reacts to a viral infection. This immune response, in turn, stimulates the production of blood cells, ensuring adequate supply for both the mother and the growing fetus.

The Benefits of "Junk DNA"

This discovery challenges the traditional view of transposons as harmful genetic elements. Instead, they appear to be essential for various biological functions, including embryonic development and tissue regeneration.

Implications for Future Research

This groundbreaking research opens up new avenues for further exploration. Scientists are eager to investigate the specific mechanisms by which transposons are activated and how they contribute to other physiological processes.

By understanding the role of transposons in pregnancy, researchers may be able to develop new strategies to treat pregnancy-related complications, such as anemia. Additionally, this knowledge could have broader implications for regenerative medicine and the development of novel therapies for various diseases.

As scientists continue to delve deeper into the mysteries of the human genome, it is becoming increasingly clear that even the most seemingly insignificant genetic elements can play a crucial role in our health and well-being.

Record Highs in Greenhouse Gases Signal Worsening Climate Crisis, UN Warns

 Greenhouse gas concentrations hit record levels in 2023, locking in years of future temperature increases, the United Nations announced. The UN’s World Meteorological Organization (WMO) reported that the three main greenhouse gases—carbon dioxide, methane, and nitrous oxide—continued to rise last year, with CO₂ accumulating in the atmosphere faster than ever. According to WMO Chief Celeste Saulo, “Another year. Another record. This should set alarm bells ringing among decision-makers,” as the world drifts further from the Paris Agreement goal of limiting warming to 1.5–2°C.

Last year, global temperatures on land and sea reached the highest levels recorded since 1850, with greenhouse gas levels climbing to pre-industrial highs: CO₂ at 420 parts per million (ppm), methane at 1,934 parts per billion, and nitrous oxide at 336 parts per billion. This translates to increases of 151%, 265%, and 125% over levels before 1750, with CO₂ alone responsible for 64% of the warming effect. CO₂’s annual rise of 2.3 ppm marked the 12th consecutive year of increases over 2 ppm—a spike caused by large-scale fossil fuel emissions.

WMO’s bulletin, released just ahead of the COP29 climate summit, highlights the risks of climate feedback loops, where warming can trigger higher emissions from natural sources. Wildfires, for example, can release more carbon, while warmer oceans may absorb less CO₂, leaving more CO₂ in the atmosphere and accelerating global warming.

With the Earth now experiencing CO₂ levels unseen since three to five million years ago—when sea levels were significantly higher and temperatures were 2–3°C warmer—WMO Deputy Chief Ko Barret warned of a "potential vicious cycle." This situation underscores the urgency of global emissions cuts to prevent even more severe impacts on ecosystems, sea levels, and communities worldwide.

New Perspectives on Pythagoras’ Theorem from High School Innovators

 A bonus math contest question has led to a remarkable breakthrough: two high school students have uncovered 10 novel proofs of Pythagoras’ theorem, a core mathematical principle that describes the relationship between the sides of right-angled triangles. Their achievement directly challenges the long-standing belief that using trigonometry to prove Pythagoras' theorem would be circular reasoning.

In 1927, mathematician Elisha Loomis argued that trigonometric proofs for Pythagoras' theorem were impossible, as all trigonometric principles rely on this very theorem. Nevertheless, in 2023, high school students Ne'Kiya Jackson and Calcea Johnson took on this mathematical challenge, persevering through obstacles to not only solve it but to publish nine additional proofs in a mathematics journal.

Pythagoras’ theorem, symbolized by the formula $a^2 + b^2 = c^2$, is essential to engineering, construction, and other fields. This fundamental law of trigonometry may even have been applied in ancient structures like Stonehenge.

Through their research, Jackson and Johnson noticed two subtly different approaches in trigonometry—one focusing on ratios of triangle sides, the other on angles. By distinguishing between these approaches, they avoided the circular reasoning that previously deterred mathematicians from proving the theorem through trigonometry.

Applying an adapted version of the Law of Sines, they found a new way to prove the theorem without traditional methods. They also noted that the boundary between “trigonometric” and “non-trigonometric” proofs may be more flexible than originally thought. By their definitions, previous mathematicians J. Zimba and N. Luzia also indirectly achieved proofs using trigonometric approaches.

In one creative proof, Jackson and Johnson calculated the side lengths of a large right triangle using smaller triangles, incorporating calculus to find measurements—a method University of Connecticut mathematician Álvaro Lozano-Robledo described as entirely unique.

Altogether, they presented one proof for right triangles with equal sides and four proofs for those with unequal sides, leaving five additional proofs as an exercise for the reader.
