A new ultrasound-based imaging tech has been developed to map the organ blood flow in four dimensions (3D + time) — a level of detail previously unattainable.
This new medical imaging tech could provide deeper insights into the circulatory system as well as enhance the diagnosis and treatment of blood circulation-related diseases.
The development comes from a team of Inserm researchers at the Physics for Medicine Institute (Inserm/ESPCI Paris-PSL/CNRS) in France.
“Compared to other established lifespan-extending interventions, Oxytocin+A5i demonstrates unique outcomes, such as significantly (over 70 per cent) increased life expectancy from the start of this therapy in old and frail male mice, and a robust decrease in mortality risk,” they wrote.
The latest study also found that the Oxytocin+A5i treatment reduced chaotic levels of some circulating blood proteins, which are key markers of ageing, bringing their levels back to a more youthful state.
However, after four months of continuous treatment, only male mice showed sustained improvement in these protein levels.
Research from the University of Gothenburg, Sweden, clarifies the complex interaction between gut bacteria and irritable bowel syndrome (IBS). Experiments demonstrate that gut bacteria can produce the important substance serotonin. The finding may lead to future treatments.
IBS is a common gastrointestinal disorder, more common in women, with symptoms such as abdominal pain, constipation or diarrhea. The cause of the disease is not clear, but the intestinal environment, including the gut microbiota and serotonin, appear to be important factors.
Serotonin is best known as a neurotransmitter in the brain, but over 90% of the body’s serotonin is produced in the gut, where it controls bowel movements via the enteric nervous system, sometimes called the “gut–brain.”

Physicists really do believe that their discipline is the basis for all other sciences because, well, it is. Recently, physicists have been applying physics to biology, using physics principles to predict how life itself evolves. Let’s take a look.

Artificial general intelligence (AGI) could be humanity’s greatest invention… or our biggest risk.
In this episode of TechFirst, I talk with Dr. Ben Goertzel, CEO and founder of SingularityNET, about the future of AGI, the possibility of superintelligence, and what happens when machines think beyond human programming.
We cover:
• Is AGI inevitable? How soon will it arrive?
• Will AGI kill us … or save us?
• Why decentralization and blockchain could make AGI safer.
• How large language models (LLMs) fit into the path toward AGI
• The risks of an AGI arms race between the U.S. and China.
• Why Ben Goertzel created Meta, a new AGI programming language.
📌 Topics include AI safety, decentralized AI, blockchain for AI, LLMs, reasoning engines, superintelligence timelines, and the role of governments and corporations in shaping the future of AI.
⏱️ Chapters.

An AI researcher going back to school for immunology
Auburn University scientists have developed a new class of materials that lets researchers precisely control free electrons, a breakthrough that could reshape the future of computing and chemical manufacturing.
Their study introduces a material system that allows fine-tuned control over how electrons behave within matter, potentially paving the way for faster computers, smarter machines, and more efficient industrial processes.
Astronomers have discovered a clever way to make a single telescope capture sharper details than should be physically possible. The technique involves feeding starlight through a special optical fibre called a photonic lantern. Anyone else thinking of a certain glowing green lantern from a movie? Alas not, instead of special powers, it splits light according to its spatial patterns like separating a musical chords into individual notes. The researchers achieved resolution that has never been achieved before without linking multiple telescopes together. When they tested the technique on a star 162 light-years away, they not only proved it works but stumbled upon an unexpected discovery, that the star’s surrounding gas disc is mysteriously lopsided.
Kirin has now worked LC-Plasma into a range of non-beer products including yoghurt beverages, green tea and other drinks. In 2020, these became the first ‘functional’ food or beverages in Japan to be allowed to be marketed as containing potentially immune-boosting ingredients.
“A food or beverage that might help improve immune function had been highly sought after in Japan for almost 30 years. But none succeeded in spite of much effort and expense,” Fujiwara says. “We conducted lots of studies and finally succeeded in meeting government requirements in 2020.”
Researchers at Kirin and NIID/JIHS have also been exploring in laboratory and animal studies the effects of LC-Plasma against various infectious diseases, including influenza, dengue fever, SARS-CoV-2 and common colds.
