But when something out of the ordinary happens, the situation can quickly get scary, because most updates are only delivered by audio announcements. A Deaf traveller may miss their train because it was moved to a different platform, or watch as their station whizzes by because the train isn’t stopping there today. They may also remain on a train carriage in an emergency after everyone else has evacuated, and have to be rescued by station staff.

Every single one of these examples has been drawn from the real life experiences of Deaf people in Sydney. But my colleagues and I are working with Sydney Trains and members of the Australian Deaf community to develop an advanced, artificial intelligence (AI)-powered signing avatar which can automatically translate audio announcements into Auslan.

Our universe might be growing by absorbing smaller “baby” universes, not just dark energy.

Researchers discovered that PLK1 triggers a process ensuring centromere preservation during cell division by activating the Mis18 complex and controlling CENP-A loading. This finding is key to understanding how cells correctly divide their genetic material, preventing diseases like cancer.

Scientists have resolved a decade-long mystery about the mechanism that maintains the centromere, the crucial region responsible for ensuring accurate DNA division during cell division.

Physicists finally know whether black holes destroy the information contained in infalling matter. The problem is that the answer hasn’t lit the way to a new understanding of space-time.

The gut-brain axis has long been a subject of interest in lifespan research, and GLP-1 agonists, already used in the treatment of obesity and diabetes, are showing promise in the field of healthspan therapeutics.

New research on gut-to-brain signaling uncovers potential links between gut hormones like GLP-1 and longevity.

Intestinal stem cells play an important role in maintaining intestinal homeostasis and repairing damaged epithelial tissue. These cells function in a regenerative manner to generate new tissue throughout the growth phase and repair damaged tissue during the aging process.¹⁰¹ The interactions between the gut microbiome and intestinal stem cells are crucial because, if this interaction is comprehended, it may be possible to address various disorders that require stem cell therapy, heal wounds, and improve the durability of organ transplants.¹⁰¹ A recent study showed a connection between hematopoietic stem cells and the microbiome through altering metabolic stress.⁶⁶ Therefore, the microbiota is crucial for maintaining microbial homeostasis, regulating metabolism, and the innate and adaptive immune systems.¹⁰¹ Furthermore, the study reveals that compositional alterations in the gut microbiome driven by dysbiosis are related to stem cell aging, metabolic dysregulations, stem cells’ epigenetic instability, and abnormal immune system activation.⁶⁶

In the field of anti-aging, stem cells are regarded to have great potential. In numerous organs, it has been demonstrated that as we age, stem cells lose their capacity for self-renewal and differentiation and run out of resources.⁸⁹ The emergence of anti-aging medications should address the dysregulation caused by aging that affects stem cells’ capacity for differentiation and self-renewal by re-regulating intrinsic and extrinsic variables. The host microbiome, hormones, local immune system, systemic inflammation, and niche structure are just a few examples of microenvironmental and systemic factors that influence stem cell aging.⁶⁶

Endogenous ethanol is a class of microbiological metabolites. Proteobacteria, including E. coli and other Enterobacteriaceae, produce ethanol with bacterial origins. High endogenous ethanol levels in the human hippocampus inhibit proliferating stem cells and reduce progenitor and stem cells.¹⁰² Additionally, when more ethanol accumulates in the gut, it enhances the permeability of the gut by disrupting epithelial tight junctions, particularly zonula occludens. This enables the movement of pathogenic microbes, their endotoxins, and ethanol across the epithelial layer, causing more immediate and adverse effects on tissues. As a result, the stem cell reserve depletes, hastening the aging process and compensating for damaged tissues.¹⁰³

Fascinating as this may sound, not all dreams serve as gateways to parallel timelines. Whether dreams return is key here. “Recurring dreams, especially those with vivid and consistent scenarios, might suggest deeper connections to other realities,” Leong claims. On the other hand, dreams tied to personal experiences often feel disjointed, with distorted time. The most surreal and incomprehensible dreams are likely the subconscious processing your life here on Earth, he says. But, if it feels like you’re visiting the dream rather than imagining it—like a play with a beginning, middle, and end—you probably are visiting this other world, under Leong’s hypothesis.

Leong also hints that strong emotions in persistent dreams could offer cosmic clues—signals of how another version of you is experiencing life in a parallel world. “Say you have a repetitive dream of being stuck in high school,” he suggests. “While it may reflect unresolved psychological themes, such as feelings of stagnation or anxiety about personal growth, it could also indicate that in another reality, you are still in high school, dealing with the same challenges your waking self has moved beyond.” This emotional resonance—like the frustration of being stuck—could ripple across dimensions, creating a feedback loop between your conscious mind here and one of your alter egos elsewhere.

YET, AS CAPTIVATING AS THIS HYPOTHESIS MIGHT BE, it runs into a significant problem: there’s no empirical evidence to back it up. Quantum phenomena, such as entanglement and nonlocality, challenge our traditional views on time and space. Yet, no scientific studies conclusively support the idea that dreams are portals to other worlds. Mainstream neuroscience and cognitive science, on the other hand, find this hypothesis heretical—if not downright unscientific.
