Deep-sea fish confirmed as a significant source of ocean carbonate

A new study offers the first direct evidence that deep-dwelling mesopelagic fish, which account for up to 94% of global fish biomass, excrete carbonate minerals at rates comparable to shallow-water species. The findings validate previous global models suggesting that marine fish are major contributors to biogenic carbonate production in the ocean.

Scientists at the University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science studied the blackbelly rosefish (Helicolenus dactylopterus), a deep-sea species living at depths of 350–430 meters (1,148–1,410 feet), to determine whether it forms and excretes intestinal carbonate—known as ichthyocarbonate. This physiological process, common among marine fish, helps maintain internal salt and water balance in saline environments and plays a critical role in marine carbon cycling.

The study, titled “Osmoregulation by the gastro-intestinal tract of at depth—implications for the global carbon cycle,” was published on July 15, 2025 in the Journal of Experimental Biology.

Scientists create an artificial cell capable of navigating its environment using chemistry alone

Researchers at the Institute for Bioengineering of Catalonia (IBEC) have created the world’s simplest artificial cell capable of chemical navigation, migrating toward specific substances like living cells do.

This breakthrough, published in Science Advances, demonstrates how microscopic bubbles can be programmed to follow chemical trails. The study describes the development of a “minimal cell” in the form of a lipid encapsulating enzymes that can propel itself through chemotaxis.

Cellular transport is a vital aspect of many biological processes and a key milestone in evolution. Among all types of movement, chemotaxis is an essential strategy used by many living systems to move towards beneficial signals, such as nutrients, or away from harmful ones.

Neutron beam platform unites simulation and biology for advanced therapy research

One of ANSTO’s advanced imaging instruments Dingo now delivers a rare fusion of simulation and radiobiology, becoming a launchpad for an innovative neutron therapy innovation.

This unique scientific capability comprises a single research platform for high-fidelity simulation, real-time dosimetry, and biological response data—all from a neutron beam instrument.

Two new papers published in Scientific Reports report how ANSTO researchers have adapted neutron tomography into a fully integrated testbed for neutron capture therapy research. The platform allows scientists to model conditions, plan experiments, and irradiate , all within a validated, operational system.

Cryonics in Space, Cryostasis Repair Science & Revival Ethics

Cryonics in space, cryostasis repair science, and revival ethics and planning are converging in 2025 to shape a bold new vision for life extension and post-biological freedom.

Join us Thursday, July 31 at 6 PM EST for a virtual service featuring two of cryonics’ leading voices:

Rudy Hoffman – Immortality Through Innovation.
Rudy opens with the visionary idea of cryonics in space and shares how today’s planning tools—annuity structures, revival trusts, and insurance-backed systems—support long-term access to biostasis. He ends with a powerful call to preserve freedom in the era of revival governance.

Alex Crouch – The Bridges to Reanimation.
Founder of Revival Research Group, Alex outlines the six bridges of cryostasis repair science, covering nanotech repair, AI orchestration, simulation, and bioprinting. His roadmap aims to make revival a transparent, collaborative goal.

Opening remarks by Neal Vanderee, officiator of the Church of Perpetual Life, connecting science, spirit, and future readiness.

The Lasting Impact Of Daniel Dennett In Philosophy And Leadership

An academic whose work reaches beyond the Ivory Tower is rare. Scholarly writing tends to be highly technical, filled with footnotes and references, and often lacks a compelling narrative to captivate the reader. Not to mention that the work itself is usually deemed irrelevant and impractical for public knowledge.

The American philosopher Daniel Dennett (1942−2024) was, without a doubt, one of these generational thinkers who transcended the academic box. Why? His writing is filled with clear and interesting thought experiments, allowing anyone to grasp his theories, which span from philosophy, cognitive science and evolutionary biology to farming, sailing, and religion. Any curious person can find a relevant topic relating to their life in Dennett’s vast body of work, and it will likely have them questioning whether they actually understood the topic in the first place.

To celebrate the life and work of Dennett, the aptly named Dennett Prize was introduced in 2024. Like Dennett, the winner should “challenge received ideas and introduce new perspectives.” The prize is presented as part of the International Center for Consciousness Studies (ICCS) annual conference, held this year in Heraklion, Crete, earlier this month. The inaugural winner of the Dennett Prize was given to Andy Clark, professor of cognitive philosophy at the University of Sussex.

Chinese nanotechnology fueling advanced bio, cyber weapons, electronic warfare tools, study warns

The Chinese military is building sophisticated biological weapons and small-scale electronic tools made with nanotechnology that could be used in covert warfare, a major study warns.

“China’s invisible arsenals encompass a range of advanced weaponry that are distinctly focused on providing the Chinese Communist Party with a range of asymmetric warfare options, including the delivery of biological, biochemical and neurobiological weapons on target populations,” according to a report by three open-source intelligence analysts.

The People’s Liberation Army, or PLA, is developing nanoweapons using highly sophisticated microscopic materials that enhance the effects of biological weapons, according to the report, titled “In the Shadows of Science: Unravelling China’s Invisible Arsenals of Nanoweapons.” It was made public earlier this month.

Design strategies for reshaping stability and sustainability of perovskite solar cells

A research team from the School of Engineering (SENG) at the Hong Kong University of Science and Technology (HKUST) has introduced comprehensive bio-inspired multiscale design strategies to address key challenges in the commercialization of perovskite solar cells: long-term operational stability. Drawing inspiration from natural systems, these strategies aim to enhance the efficiency, resilience, and adaptability of solar technologies.

Their paper, titled “Bio-Inspired Multiscale Design for Perovskite Solar Cells,” has been published in Nature Reviews Clean Technology.

The approaches focus on leveraging insights from to create that can better withstand environmental stressors and prolonged use.

Want to boost your brain as you age? Music might be the answer

Long-term musical training may mitigate the age-related decline in speech perception by enhancing cognitive reserve, according to a study published in PLOS Biology by Claude Alain from the Baycrest Academy for Research and Education, Canada, and Yi Du from the Chinese Academy of Sciences.

Normal aging is typically associated with declines in sensory and cognitive functions. These age-related changes in perception and cognition are often accompanied by increased neural activity and functional connectivity—the statistical dependence of activity between different brain regions—in widely distributed neural networks.

The recruitment of neural activity and strengthening of functional connectivity are thought to reflect a compensatory strategy employed by older adults to maintain optimal cognitive performance.

Study finds genetics shape health impact of leisure versus work physical activity

The benefits of exercise and its positive influence on physical and mental health are well documented, but a new Yale and VA Connecticut study sheds light on the role genetics plays for physical activity, accounting for some of the differences between individuals and showing differences in biology for physical activity at leisure versus physical activity at work and at home.

Using data from the Million Veteran Program (MVP), a genetic biobank run by the U.S. Department of Veterans Affairs, the researchers analyzed genetic influences on leisure, work, and home-time physical activity. They wanted to understand how genetics impacts these three types of physical activity and compare their health benefits.

The study included nearly 190,000 individuals of European ancestry, 27,044 of African ancestry, and 10,263 of Latin-American ancestry. To study the genetics of physical activity during leisure time, the researchers also added data from the UK Biobank, which included about 350,000 individuals.
