Researchers have discovered a low-cost, direct method to turn commonly used 3D printable polymers into lightweight, ultra-tough, biocompatible hybrid carbon microlattices. More importantly, these microlattices are 100 times stronger than regular polymers.
Few things in the Universe keep the beat as reliably as an atom’s pulse.
Yet even the most advanced ‘atomic’ clocks based on variations of these quantum timekeepers lose count when pushed to their limits.
Physicists have known for some time that entangling atoms can help tie particles down enough to squeeze a little more tick from every tock, yet most experiments have only been able to demonstrate this on the smallest of scales.
The global dairy industry is changing. Among the disruptions is competition from food alternatives not produced using animals – including potential challenges posed by synthetic milk.
Synthetic milk does not require cows or other animals. It can have the same biochemical make up as animal milk, but is grown using an emerging biotechnology technique know as “precision fermentation” that produces biomass cultured from cells.
More than 80 percent of the world’s population regularly consume dairy products. There have been increasing calls to move beyond animal-based food systems to more sustainable forms of food production.
According to a new meta-analysis, gene variants associated with a person’s blood type may be linked to their risk of early stroke.
“Non-O blood types have previously been linked to a risk of early stroke, but the findings of our meta-analysis showed a stronger link between these blood types with early stroke compared to late stroke, and in linking risk mostly to blood type A,” said study author Braxton D. Mitchell, PhD, MPH, of University of Maryland School of Medicine in Baltimore. “Specifically, our meta-analysis suggests that gene variants tied to blood types A and O represent nearly all of those genetically linked with early stroke. People with these gene variants may be more likely to develop blood clots, which can lead to stroke.”
48 studies on genetics and ischemic stroke from North America, Europe, and Asia were reviewed in the meta-analysis. 16,927 people with stroke and 576,353 people who did not have a stroke were included in the studies. Of those with stroke, 5,825 people had early onset stroke and 9,269 people had late onset stroke. Early onset stroke was defined as an ischemic stroke occurring before age 60 and late-onset stroke was older than 60 years old.
A team of researchers from Stanford University has constructed the first synthetic microbiome model, built entirely from scratch and encompassing more than 100 different bacterial species. It’s hoped the achievement will revolutionize gut microbiome research by offering scientists a consistent working model for future experiments.
Trillions of microbes live inside our guts. Perhaps one of the most significant discoveries in medical science over recent decades has been how deeply these microbes influence our general health. From affecting how well drugs we consume work, to modulating our immune systems, the gut microbiome plays a powerful role in all aspects of our health.
It’s also mind-bendingly complex. No two people share exactly the same gut microbiome composition. And while researchers frequently home in on ways particular bacteria influence metabolic mechanisms, it has been difficult to translate these findings into actual clinical therapies for humans.
A treatment developed by a Japanese doctor and his team is helping women with premature menopause to give birth with their own eggs. Premature menopause is triggered by a malfunctioning of the ovaries and affects even those in their teens. The treatment involves activating dormant primordial follicles. We focus on the method, which has been described by TIME Magazine as a global breakthrough. We also introduce herbs that can alleviate symptoms such as those of menopause.
Astronomers report the detection of a new brown dwarf as part of the Ophiuchus Disk Survey Employing ALMA (ODISEA) program. The newfound object, designated SSTc2d J163134.1–24006, appears to be experiencing a quasi-spherical mass loss. The discovery was detailed in a paper published September 2 on the arXiv pre-print repository.
Brown dwarfs are intermediate objects between planets and stars, occupying the mass range between 13 and 80 Jupiter masses (0.012 and 0.076 solar masses). They can burn deuterium but are unable to burn regular hydrogen, which requires a minimum mass of at least 80 Jupiter masses and a core temperature of about 3 million K.
A team of astronomers led by Dary Ruiz-Rodriguez of the National Radio Astronomy Observatory (NRAO) in Charlottesville, Virginia, have investigated SSTc2d J163134.1–24006, initially identified as a faint stellar object, under the ODISEA project, which is dedicated to study the entire population of protoplanetary disks in the Ophiuchus Molecular Cloud. They found that SSTc2d J163134.1–24006 is most likely a brown dwarf with a mass of about 0.05 solar masses, and an elliptical shell of carbon monoxide (CO).
An alzheimer’s-proof brain: a groundbreaking case.
In a groundbreaking case researchers from the Massachusetts General Hospital have discovered a gene variant that seems to have disrupted the pathology of Tau Protein. The case of Aliria Rosa Piedrahita de Villegas.

Or so goes the theory. Most CIM chips running AI algorithms have solely focused on chip design, showcasing their capabilities using simulations of the chip rather than running tasks on full-fledged hardware. The chips also struggle to adjust to multiple different AI tasks—image recognition, voice perception—limiting their integration into smartphones or other everyday devices.
This month, a study in Nature upgraded CIM from the ground up. Rather than focusing solely on the chip’s design, the international team—led by neuromorphic hardware experts Dr. H.S. Philip Wong at Stanford and Dr. Gert Cauwenberghs at UC San Diego—optimized the entire setup, from technology to architecture to algorithms that calibrate the hardware.
The resulting NeuRRAM chip is a powerful neuromorphic computing behemoth with 48 parallel cores and 3 million memory cells. Extremely versatile, the chip tackled multiple AI standard tasks—such as reading hand-written numbers, identifying cars and other objects in images, and decoding voice recordings—with over 84 percent accuracy.
Strange diamonds from an ancient dwarf planet in our solar system may have formed shortly after the dwarf planet collided with a large asteroid about 4.5 billion years ago, according to scientists.
The research team says they have confirmed the existence of lonsdaleite, a rare hexagonal form of diamond, in ureilite meteorites from the mantle of the dwarf planet.
Lonsdaleite is named after the famous British pioneering female crystallographer Dame Kathleen Lonsdale, who was the first woman elected as a Fellow to the Royal Society.
