Imagine a world where the smart watch on your wrist never ran out of charge, because it used your sweat to power itself.
It sounds like science fiction but researchers have figured out how to engineer a bacterial biofilm to be able to produce continuous electricity from perspiration.
They can harvest energy in evaporation and convert it to electricity which could revolutionise wearable electronic devices from personal medical sensors to electronics.
A more long-term alternative to using steroids.
It is estimated that more than 250 million people globally suffer from asthma, which also causes hundreds of thousands of fatalities annually. Therefore, finding a cure for the condition could be life-changing for a large number of people.
Scientists have now developed a new potential long-term treatment for asthma. The method, which not only treats the symptoms of asthma but also targets one of its causes, functions by preventing the mobility of a certain kind of stem cell known as a pericyte.
Tightness of the chest, difficulty breathing, coughing, and wheezing — a person suffering from allergic asthma can start experiencing all of these symptoms after inhaling an allergen. Though asthma affects about 340 million people worldwide, allergic asthma is the most prevalent form, with 90 percent of children with asthma having allergies, compared to 50 percent of adults with asthma.
Now, researchers led by Laurent Reber (Infinity, Toulouse) and Pierre Bruhns (Humoral Immunity, Institut Pasteur, Paris) and French company NEOVACS have developed a vaccine that could provide long-term protection against allergic asthma and reduce the severity of the symptoms, improving patient quality of life dramatically.
Burial sites in the Eastern Mediterranean from the period around 2000 BCE show evidence of outbreaks of disease that likely contributed to the fall of three great civilizations: the Minoan on the island of Crete, the Akkadian in what is Turkey today, and Egypt’s Old Kingdom.
The pathogens found in the DNA of old bones indicate significant outbreaks of typhoid fever and the plague. The emergence of widespread disease in this area of the world at that time may be related to climate change, or pressures from new waves of human migration coming from outside the region. But a paper published in Current Biology on July 25, 2022, shows widespread infections involving the bacterium Yersinia pestis, responsible for the many incidents of plague that occurred in ancient civilizations all the way to the era of Justinian 1st in the 6th century CE Eastern Roman Empire which modern scholars labelled Byzantine. Also found in burial sites is widespread evidence of Salmonella Enterica the cause of typhoid/enteric fever.
This evidence coincides with a period of major geopolitical transformation from 2,290 to 1909 BCE. During this time the Old Kingdom, the Akkadian Empire, and the Middle Minoan civilization were all disrupted. The periods are associated with societal and population declines throughout much of the Eastern Mediterranean. Did these depopulating diseases come from elsewhere brought in by migration and invasion? Were there environmental factors such as a change in the climate? Was there degradation of agricultural lands leading to famine, and a general weakening of the local population?
Yes, it does. Although OrganEx helps revitalize pigs’ organs, it’s far from a deceased animal being brought back to life. Rather, their organs were better protected from low oxygen levels, which occur during heart attacks or strokes.
“One could imagine that the OrganEx system (or components thereof) might be used to treat such people in an emergency,” said Porte.
The technology could also help preserve donor organs, but there’s a long way to go. To Dr. Brendan Parent, director of transplant ethics and policy research at NYU Grossman School of Medicine, OrganEx may force a rethink for the field. For example, is it possible that someone could have working peripheral organs but never regain consciousness? As medical technology develops, death becomes a process, not a moment.
A biotechnology company based in Israel wants to replicate a recent experiment that successfully created an artificial mouse embryo from stem cells — only this time with human cells.
Scientists at Weizmann’s Molecular Genetics Department grew “synthetic mouse embryos” in a jar without the use of sperm, eggs, or a womb, according to a paper published in the journal Cell on August 1. It was the first time the process had been successfully completed, Insider’s Marianne Guenot reported.
The replica embryos could not develop into fully-formed mice and were therefore not “real,” Jacob Hanna, who led the experiment, told the Guardian. However, scientists observed the synthetic embryos having a beating heart, blood circulation, the start of a brain, a neural tube, and an intestinal tract.
I believe that these microbes are not just simple organisms but are some sorta biological singularity seeds that activate over millions of years developing life slowly and may be exterrestial in origin.
Researchers from Hokkaido University in Japan have found new evidence that the chemical components necessary to build DNA may have been carried to Earth by carbonaceous meteorites, some of the earliest matter in the solar system, as they report in a study published Tuesday in Nature Communications. Although these kinds of materials make up about 75 percent of all asteroids, they rarely fall to Earth, limiting how often scientists can study them. Yet they are troves of information: Scrutinizing these space rocks can tell stories about unique cosmic locations. Their contents may also help reveal the ancient chemical reactions that made our world a living planet.
Specifically, several meteorites have been found to contain nucleobases. These chemicals, called the building blocks of life, make up the nucleic acids inside DNA and RNA. Of the five major nucleobases, previous meteorite studies detected only three of them, named adenine, guanine, and uracil. But the present research proves for the first time that two more—cytosine and thymine—can exist within space rocks.
“The detection of all primary DNA and RNA nucleobases in meteorites indicates that these molecules have been supplied to the early Earth before the onset of life,” says Yasuhiro Oba, lead author of the study and an associate professor at Hokkaido University. ” In other words, we got information about the inventory of organic molecules related to DNA and RNA before any life arose on the Earth.” One of the oldest specimens in the study clocks in at about 4.6 billion years old, which is even older than the solar system.

Big scientific breakthroughs often require inventions at the smallest scale. Advances in tissue engineering that can replace hearts and lungs will require the fabrication of artificial tissues that allow for the flow of blood through passages that are no thicker than a strand of hair. Similarly, miniature softbotic (soft-robot) devices that physically interact with humans safely and comfortably will demand the manufacture of components with complex networks of small liquid and airflow channels.
Advances in 3D printing are making it possible to produce such tiny structures. But for those applications that require very small, smooth, internal channels in specific complex geometries, challenges remain. 3D printing of these geometries using traditional processes requires the use of support structures that are difficult to remove after printing. Printing these models using layer-based methods at a high resolution takes a long time and compromises geometric accuracy.
Researchers at Carnegie Mellon University have developed a high-speed, reproducible fabrication method that turns the 3D printing process “inside out.” They developed an approach to 3D print ice structures that can be used to create sacrificial templates that later form the conduits and other open features inside fabricated parts.
