The secondary market for decades old, low-tech John Deere tractors has been booming for years as farmers have sought reliable tractors that they can actually fix without having to deal with John Deere’s repair monopoly. A Canadian company has seen that demand and came up with a radical thought: What if they made a new, repairable, “no-tech” tractor to solve what has become a gigantic pain point for farmers?

Alberta’s Ursa Ag says that it has been inundated with demand after announcing its tractor, which costs roughly half as much as a Deere and has the benefit of not being a repair nightmare. We have for years covered the frustration that farmers have felt as they have been locked out of their Deere tractors with digital rights management systems that prevent them from fixing their machinery, tractors that won’t run because of minor sensor failures, and crops that literally die on the vine as they wait for an “authorized” repair person to fix tractors during critical harvesting periods.

Scientists have uncovered a new way to control an unusual quantum phenomenon that could one day help power electronic devices without batteries.

An international research team led by Professor Dongchen Qi from the Queensland University of Technology (QUT) School of Chemistry and Physics and Professor Xiao Renshaw Wang from Nanyang Technological University in Singapore investigated the physics behind the nonlinear Hall effect (NLHE), a quantum phenomenon with significant potential for future energy-harvesting technologies.

Unlike the classical Hall effect, the NLHE can convert alternating electrical signals directly into direct current. This means energy from wireless transmissions or other ambient sources could potentially be transformed into usable electricity without relying on conventional diodes or other bulky electronic components.

“The NLHE is a sophisticated quantum phenomenon in condensed matter physics where a voltage is generated perpendicular to an applied alternating current, even in the absence of a magnetic field,” Professor Qi said.

“This effect allows us to convert alternating signals straight into direct current, which is what’s needed to power electronic devices. In principle, it means sensors or chips that could operate without batteries, drawing energy from their environment.”

Older adults who cut back on dietary fat or reduced the amount of animal-based protein they consumed showed signs of becoming biologically younger, according to new research from the University of Sydney.

The study, published in Aging Cell, found that adults between the ages of 65 and 75 experienced reductions in their estimated ‘biological age’ after following specific diets for just four weeks. Researchers say the findings suggest dietary changes later in life may quickly improve markers linked to aging and overall health.

The research was led by Dr. Caitlin Andrews from the University of Sydney’s School of Life and Environmental Sciences. While the results are promising, the scientists emphasized that the study provides only an early indication rather than definitive proof that diet can reverse aging. They say larger and longer studies are needed to determine whether these biological changes lower disease risk over time and whether the same effects occur in other age groups.

Scientists may have discovered a powerful new link between the gut microbiome, aging, and liver cancer. New research presented at Digestive Disease Week® (DDW) 2026 suggests that restoring gut bacteria to a more youthful state could help protect the liver, reduce age related damage, and potentially lower cancer risk.

The findings come from a mouse study focused on the microbiome, the vast community of bacteria and other microbes living in the digestive system. Researchers found that giving older mice back their own younger gut microbes produced striking effects throughout the body, especially in the liver.

MIT scientists discover millions of “silent synapses” in the adult brain– www.sciencedaily.com

MIT neuroscientists have uncovered a surprising feature of the adult brain. It contains millions of “silent synapses,” which are immature connections between neurons that remain inactive until they are needed to help form new memories.

For many years, scientists believed these silent synapses existed only during early development, when the brain is rapidly learning about the world. But the MIT team found that in adult mice, roughly 30 percent of synapses in the brain’s cortex are still silent. This suggests the adult brain holds a large reserve of unused connections that can be activated when new information arrives.

Researchers say this hidden pool of synapses may explain how the brain continues to learn throughout life without disrupting existing memories.

“These silent synapses are looking for new connections, and when important new information is presented, connections between the relevant neurons are strengthened. This lets the brain create new memories without overwriting the important memories stored in mature synapses, which are harder to change,” says Dimitra Vardalaki, an MIT graduate student and the lead author of the study.

Scientists in Sweden have developed a more reliable way to create insulin-producing cells from human stem cells, bringing new momentum to efforts to treat type 1 diabetes. The research, published in Stem Cell Reports, shows that these lab-grown cells can effectively control blood sugar in tests and even reverse diabetes in mice.

Type 1 diabetes develops when the immune system attacks and destroys the pancreas’s insulin-producing cells. Without insulin, the body cannot properly absorb glucose from the bloodstream, leading to dangerous blood sugar levels. Replacing these lost cells has long been seen as a promising solution, but earlier attempts to grow them from stem cells have produced inconsistent results.

“We have developed a method that reliably produces high-quality insulin-producing cells from multiple human stem cell lines. This opens up opportunities for future patient-specific cell therapies, which could reduce immune rejection,” says Per-Olof Berggren, professor at the Department of Molecular Medicine and Surgery, Karolinska Institutet, and corresponding author alongside Siqin Wu, researcher at Spiber Technologies AB

For decades, physicists have been trying to answer a fundamental question: can electrons move like a perfectly smooth, frictionless fluid governed by a universal quantum value? Detecting this unusual behavior has proven extremely challenging. In real materials, tiny imperfections such as atomic defects and impurities tend to disrupt these delicate quantum effects, making them nearly impossible to observe.

Now, researchers at the Department of Physics, Indian Institute of Science (IISc), working with collaborators from the National Institute for Materials Science in Japan, have finally identified this elusive quantum fluid in graphene. This material consists of a single layer of carbon atoms arranged in a flat sheet. Their findings, reported in Nature Physics, open a new path for studying quantum phenomena and position graphene as a powerful platform for exploring effects that were previously out of reach in laboratory settings.

“It is amazing that there is so much to do on just a single layer of graphene even after 20 years of discovery,” says Arindam Ghosh, Professor at the Department of Physics, IISc, and one of the corresponding authors of the study.

… A research team led by Kavita Pandey of the Centre for Nano and Soft Matter Sciences (CeNS), a Department of Science and Technology (DST) institute in Bengaluru, working in collaboration with researchers from Shiv Nadar Institution of Eminence in Greater Noida, has developed a new composite material that makes aluminium batteries more stable and longer-lasting.

“Aluminium batteries have attracted attention because aluminium is widely available, inexpensive, and can store more charge per atom than lithium. But there has been a major hurdle: the materials inside these batteries tend to break down quickly. Over repeated charging, they crack or dissolve into the liquid inside the battery, causing it to lose power,” DST pointed out…

The result is a composite that acts like a support structure, holding the battery material together while also helping electricity and ions move more smoothly.This seemingly simple change made a measurable difference. Tests showed that the new material reduced the amount of vanadium dissolving into the battery liquid by more than four times compared to the original material.

As a result, the battery retained more than 73% of its capacity after 100 charge cycles, and around 59% even after 500 cycles. In comparison, conventional versions degrade much faster. In practical terms, that means a battery that lasts longer and performs more reliably…

For the first time, researchers have detected empty voids moving faster than the speed of light — and they blazed past that cosmic speed limit without breaking the laws of relativity.

A recent study shows the voids’ acceleration. Researchers used recent advances in ultrafast electron microscopy to measure voids in phonon-polariton waves zooming around inside a thin flake of boron nitride. Phonon-polaritons are quasiparticles formed from photons (quantized light) coupled with tiny vibrations, and they act like light and sound waves combined.

Scientists at Stanford Medicine have identified a naturally occurring molecule that appears to mimic some of the weight loss effects of semaglutide, the drug widely known as Ozempic. In animal studies, the molecule reduced appetite and body weight while avoiding several common side effects such as nausea, constipation, and muscle loss.

The molecule, called BRP, works through a different but related biological pathway and activates distinct groups of neurons in the brain. This suggests it may offer a more precise way to control appetite and metabolism.

The communication uses magnetic field underground communication source technology, and is the world’s first successful attempt at it. Instead of relying on conventional radio waves, which get absorbed almost instantly by rock and soil, ETRI’s system uses low-frequency magnetic fields.

The setup includes a 1-meter-diameter transmitting antenna on the surface and a small, handheld-sized receiving sensor underground operating at around 15 kHz. That’s enough bandwidth to support a data rate of 2 to 4 kbps, which is sufficient for clear, two-way voice communication.

The team successfully tested bidirectional communication between the ground level and the fifth underground layer of a limestone mine, an environment where existing wireless technology cannot reach.

Previous research had only managed a few tens of meters. ETRI pushed that to 100 meters, and the technology is designed to go further.

Two dimensional materials have drawn intense interest because their electronic and magnetic properties could power future technologies. Scientists have traditionally treated these two behaviors as separate. Engineers at Illinois Grainger Engineering have now shown that they are connected by the same underlying mathematics.

In a study published in Physical Review X, researchers from The Grainger College of Engineering at the University of Illinois Urbana Champaign demonstrated how specially designed two dimensional magnetic systems can follow the same equations that describe mobile electrons in graphene. This mathematical connection could influence the design of radiofrequency devices and also provide researchers with a powerful new way to analyze and engineer these materials.

“It’s not at all obvious that there is an analogy between 2D electronics and 2D magnetic behaviors, and we’re still amazed at how well this analogy works,” said Bobby Kaman, the study’s lead author. “2D electronics are very well studied thanks to the discovery of graphene, and now we’ve shown that a not-so-well-studied class of materials obeys the same fundamental physics.”
