Theurgy was a system of magical practices in the late Roman Empire. It was applied Neoplatonism. The theurgists aimed to enable human bodies to assume divine attributes, that is, to become deities. I aim to show that much of the structure of theurgical Neoplatonism appears in transhumanism. Theurgists and transhumanists share a core Platonic-Pythagorean metaphysics. They share goals and methods. The theurgists practiced astrology, the reading of entrails, the consultation of oracles, channeling deities, magic, and the animation of statues. The transhumanist counterparts of those practices are genetics, self-tracking with biosensors, artificial intellects like Google and Siri, brain-computer interfaces, programming, and robotics. Transhumanist techno-theurgy shows how Neoplatonism can be a modern philosophical way of life.

The University of Cape Town, along with the Giraffe Conservation Foundation, have conducted a large-scale study identifying significant cranial shape differences between four genetically distinct giraffe species. The findings suggest that these species exhibit unique developmental and morphological characteristics, which have implications for conservation efforts.

Taxonomic classification is critical for guiding good conservation strategies. Giraffes have long been categorized as one species with geographic variants, though advancements in research are reshaping this perspective.

In the study, “Heads Up—Four Giraffa Species Have Distinct Cranial Morphology,” published in PLOS ONE, researchers examined 515 giraffe skulls with 3D geometric morphometrics to analyze patterns of cranial variability. The dataset, the largest of its kind, included specimens from museum collections, wild populations, and taxidermy sources across Africa.

Benonisdottir et al. review the genetics of reproductive traits and examine how these associate with links to health, behavior, aging and longevity as well as outcomes for offspring.

The growth of maize, sugarcane and sorghum has been greatly boosted by modifying the plants to take advantage of higher carbon dioxide levels now found in the air.

This was done by simply increasing the activity of two genes, says Coralie Salesse-Smith at the University of Illinois. The finding should lead to the creation of new varieties whose yields go up as CO₂ levels continue to rise.

For most of the time that photosynthetic cells that turn sunlight into food have existed, atmospheric levels of CO₂ have been much higher (and the planet has been much hotter). As CO₂ levels fell particularly low from about 35 million years ago, it exacerbated a fundamental flaw in photosynthesis that involves probably the most abundant protein on the planet, called rubisco.

Furthermore, GDF-15 levels have been positively associated with the aging process. In fact, Tanaka et al. (Tanaka et al. 2018) showed that this cytokine had the strongest positive correlation with age in humans, and several reports describe higher levels of GDF-15 in older individuals (Semba et al. 2020; Doerstling et al. 2018; Liu et al. 2020). Aging is characterized by a decline in physiological function and changes in body composition, being a major risk factor for a variety of chronic diseases. As such, GDF-15 is also associated with several age-related diseases, including cardiovascular disease (Echouffo-Tcheugui et al. 2021), cancer (Wischhusen et al. 2020), metabolic syndrome (Ho et al. 2023; Carballo-Casla et al. 2022), or diabetes (Ouyang et al. 2020; Merchant et al. 2023), among others (Candia et al. 2021; Iglesias et al. 2023). In addition, it has been proposed as a biomarker for the risk of death in patients with cardiovascular conditions and an accurate all-cause mortality marker (Candia et al. 2021; Iglesias et al. 2023; Nopp et al. 2021). GDF-15 has also been positively associated with deteriorated muscle function and sarcopenia (Semba et al. 2020; Kim et al. 2022, 2020; Nakajima et al. 2019; Lee et al. 2022), a highly prevalent condition among the elderly that increases the risk of frailty (Picca et al. 2020).

It is widely accepted that human aging may be influenced by epigenetic alterations (López-Otín et al. 2023). In this sense, age biomarkers based on DNA methylation have proven useful in predicting the risk of age-related diseases and mortality (Fransquet et al. 2019). Among several developed epigenetic clocks, DNAm GrimAge has shown a higher prediction capacity of mortality and morbidity risk (Lu et al. 2022). Notably, GDF-15 is one of the markers included for the calculation of this clock (Lu et al. 2019). Thus, understanding the interplay between GDF-15 and aging can be crucial for improving the assessment of and management of age-associated conditions.

For all this, the aim of this study was to characterize the changes in circulating GDF-15 levels with age in a population of healthy individuals from the Balearic Islands and investigate its potential associations with different epigenetic and biological clocks, physical performance and other age-related biomarkers.

Cultivators are using genetic sequencing and are hybridizing cultivars from ever more distant lineages to hunt for improvements, plus sheer aesthetic novelty. Technological advancements have allowed for fungal cells to more easily be manipulated during breeding, and developments in chromatographic potency testing enables growers to dial in on what alteration methods result in stronger mushrooms, which can be sold to consumers at prices in excess of $10 per gram more. The arrival of such methods means the era of amateur “bro science” in psychedelic mycology is over, Mattucci says. The age of uninformed tinkering and anecdote-driven science is giving way to cultivation driven by deeper and more complex scientific—and mycological—knowledge. “This is only the beginning” of super-strength potencies, Mattucci says, “and it’s going to be pretty insane over the next decade.”

One group that may stand to benefit are people who experience gastrointestinal issues from mushrooms, says Sam Gandy, an ecologist and independent psychedelics researcher who is conducting a survey on the variable psychedelic effects attributed to different varieties. Gandy notes that some people suffer unpleasant physical sensations, known as “body load” issues, when ingesting psilocybin mushrooms—particularly P. cubensis. “But testimonials suggest this varies with species and generally the more potent species seem to be smoother on the body,” he says. “At present it isn’t altogether clear why this is the case, but the more rapid release of psilocybin from less fungal matter may be something to do with it,” he says. Others report a better subjective quality of experience with higher strength mushrooms, Gandy adds.

Middlemen get a bad rap for adding cost and complications to an operation. So, eliminating the go-betweens can reduce expense and simplify a process, increasing efficiency and consumer happiness.

James Dahlman and his research team have been thinking along those same lines for stem cell treatments. They’ve created a technique that eliminates noisome middlemen and could lead to new, less-invasive treatments for blood disorders and genetic diseases. It sidesteps the discomfort and risks of current treatments, making life easier for patients.

“This would be an alternative to invasive hematopoietic stem cell therapies—we could just give you an IV drip,” said Dahlman, McCamish Early Career Professor in the Wallace H. Coulter Department of Biomedical Engineering. “It simplifies the process and reduces the risks to patients. That’s why this work is important.”

It’s estimated that anywhere from three to seven percent of school-age children may have dyslexia, a neurodevelopmental issue that affects reading, spelling, and writing. There are different ideas about why dyslexia occurs, although they relate to dysfunction in brain networks, and are likely due to multiple causes in affected individuals; the disorder may not have a singular underlying cause. Neuroimaging studies of dyslexic individuals have produced inconsistent results.

Since dyslexia has a heritable, and therefore, genetic component, scientists wanted to know more about how genetics and brain mapping could reveal more about the pathology of dyslexia. A new study has shown that carriers of genetic variants that increase the risk of dyslexia also have changes in brain structure, which occur in areas that are related to language, motor coordination, and vision. The findings have been reported in Science Advances.
