In an unexpected fusion of plastic surgery and cancer treatment, researchers at UC San Francisco have developed a groundbreaking technique that uses engineered fat cells to starve tumors and prevent their growth. Drawing inspiration from liposuction and fat transfer procedures, this innovative approach could revolutionize cancer therapy by utilizing modified fat cells to deprive tumors of the nutrients they need to survive.

Using CRISPR gene-editing technology, the scientists transformed ordinary white fat cells into “beige” fat cells—cells that burn calories aggressively to generate heat. In their experiments, these engineered fat cells were implanted near tumors, much like how plastic surgeons transfer fat between different body areas. The result was remarkable: the beige fat cells consumed large amounts of nutrients, starving the tumor cells and impeding their growth, even when the fat cells were placed far from the tumor site.

A team of chemists and microbiologists at Michigan State University has developed a groundbreaking all-optical method that can detect the natural vibrational frequencies produced by individual viruses, offering a novel way to identify them. The research, published in Proceedings of the National Academy of Sciences, demonstrates how light can be used to detect nanoparticle-scale objects, including viruses, by analyzing the resulting patterns of vibration.

Prior research had shown that when light is directed at tiny objects like nanoparticles, it causes them to vibrate slightly. The vibrations create unique patterns, which can be used to identify different materials. Inspired by this, the Michigan State team wondered if the technique could also be applied to biological agents like viruses and bacteria.

Researchers at Delft University of Technology in The Netherlands have developed an innovative 3D-printed brain-like environment designed to mimic the natural growth conditions for neurons. By using tiny nanopillars to replicate the brain’s soft tissue and extracellular matrix fibers, this groundbreaking model aims to provide new insights into how neurons form networks and how neurological disorders, such as Alzheimer’s, Parkinson’s, and autism, may affect these connections.

Traditional petri dishes used in neuron studies are flat and rigid, which contrasts sharply with the brain’s soft, fibrous environment. To overcome this limitation, the researchers designed nanopillar arrays using a precise 3D laser printing technique known as two-photon polymerization. These nanopillars, which are thousands of times thinner than a human hair, create a structure that tricks neurons into thinking they are growing in a natural, soft, brain-like environment. This setup influences how neurons grow, connect, and mature in ways that traditional petri dishes cannot.

Bioprinting has long been seen as a game-changing technology in fields like regenerative medicine, drug testing, and tissue engineering. However, the high cost of bioprinters has limited access to this powerful tool, especially for researchers and educators with smaller budgets. That’s about to change thanks to the Printess, an affordable modular and open-source bioprinter developed by Stanford University’s Skylar-Scott Lab. Priced at just $250, the Printess is set to democratize bioprinting, making it accessible to a global community of researchers and educators.

Developed by Mark Skylar-Scott and his team, the Printess is a low-cost yet highly capable tool designed for accessibility, customization, and scalability. In contrast to professional-grade bioprinters that can cost anywhere from $10,000 to over $200,000, the Printess removes financial barriers by offering an affordable alternative that allows nearly any lab to incorporate bioprinting into their work.

Tuberculosis (TB) remains one of the deadliest infectious diseases worldwide, and with the rise of drug-resistant strains, treatment has become even more challenging. However, a significant breakthrough in the fight against drug-resistant TB has emerged from a global clinical trial led by Harvard Medical School, in collaboration with the endTB project. The findings, published on January 29 in The New England Journal of Medicine, reveal three new drug regimens that are both safe and effective for treating rifampin-resistant TB.

The endTB project, which includes partnerships with Médecins Sans Frontières, Partners In Health, Interactive Research and Development, and academic institutions worldwide, has made a major stride in improving treatment options for TB patients, particularly those resistant to rifampin, a key first-line antibiotic.

In a groundbreaking moment for pediatric surgery, 16-year-old Rev from Aurora, Colorado, became the first patient to undergo gallbladder removal using the remotely controlled Senhance robotic system at HCA HealthONE Rocky Mountain Children’s. What’s more impressive is that Rev was discharged the same afternoon and was back on his feet just two days later, dancing at his prom. This quick recovery marks a dramatic shift in how common surgeries are being performed, thanks to cutting-edge technology that promises to make procedures faster, safer, and less invasive.

Historically, surgeries like gallbladder removal required extended hospital stays and weeks of painful recovery. However, with innovations from Asensus Surgical and its Senhance system, these processes are becoming more efficient, even in the delicate world of pediatric surgery—a field known for its unique challenges.

Imagine a future where doctors deploy thousands of microscopic robots to clear blocked arteries or deliver precise treatments. Researchers at Hanyang University have taken a major step toward this possibility by developing microrobots that can self-organize into swarms, tackle obstacles, and even transport heavy loads. In a groundbreaking study published in the journal Device, scientists demonstrated how these robots, each smaller than a grain of salt, can work together like an army of ants to solve complex problems.

Each of these miniature robots, measuring just 600 micrometers tall (about half a millimeter), is made using a process similar to ice cube molding, allowing researchers to create hundreds of these tiny robots cost-effectively. The robots are embedded with magnetic particles called neodymium-iron-boron (NdFeB), enabling them to respond to external magnetic fields and interact with one another. This allows them to form various shapes and structures to adapt to different challenges.

From ancient Egypt’s use of electric fish to treat headaches to the creation of pacemakers for heart rhythm regulation in the 1950s, bioelectronic medicine—an emerging field that utilizes electrical signals rather than drugs to diagnose and treat diseases—has come a long way. But where does the field stand today, and what promising opportunities lie ahead for transformative therapies and diagnostics? New research led by Imanuel Lerman, head of the Lerman Lab at the UC San Diego Qualcomm Institute and UC San Diego School of Medicine, sheds light on the exciting future of bioelectronic medicine.

“This paper is a roadmap for the future of the field,” said Lerman. “We’re planting a flag to show what we’re planning to do and why, providing the resources for those who want to dive deeper into the research.” Published in Bioelectronic Medicine, the study aims to chart the course for bioelectronic medicine’s next phase.

When the topic of germline editing arises, most scientists wince. The infamous CRISPR-baby scandal involving the Chinese scientist He Jiankui, who altered human embryos, brought the conversation to the forefront. Editing reproductive cells or embryos not only affects the individual being treated but also introduces permanent changes to their genetic code, which can be passed down through generations—whether beneficial or harmful. As a result, germline editing is banned in most countries, with He Jiankui serving jail time for his actions. Although he was released, his controversial experiment remains a flashpoint for debate in the scientific community.

He’s CRISPR-edited twins, Lulu and Nana, are reportedly growing normally as toddlers, though details of their health remain vague. Despite worldwide condemnation of his methods, He’s work ignited a broader discussion about the future of germline editing. In theory, such edits could be used to eliminate inherited diseases, benefiting entire family lines. But where does the line between disease prevention and designer babies lie? Should gene editing be reserved only for serious illnesses, or can it extend to genetic traits like intelligence or physical appearance?

A groundbreaking innovation in epilepsy management is offering new hope for individuals with photosensitive epilepsy. Researchers from the University of Glasgow and the University of Birmingham have developed a pair of advanced glasses that can shield users from light wavelengths known to trigger seizures. This breakthrough could enhance the safety of epilepsy patients during everyday activities like watching television, using computers, or enjoying entertainment.

The revolutionary glasses feature liquid crystal lenses capable of blocking harmful light frequencies, with a particular focus on the 660-720nm wavelength range, which is most likely to provoke seizures in photosensitive individuals. The lenses’ ability to filter out these wavelengths has been shown to reduce the risk of seizures, offering a new layer of protection.

Sutures have long been the go-to method for closing large and deep wounds in the skin, promoting faster healing by physically bringing the edges of the wound back together. Without them, injuries heal more slowly, often leave larger scars, and have a higher risk of infection. However, traditional sutures come with their own set of challenges: movement of the affected area can cause the stitches to open up, and they typically need to be removed by a doctor once the healing process is complete. Now, scientists at Donghua University in China have developed a groundbreaking new type of suture that could address these issues and accelerate the healing process.

The innovation lies in a specialized mechanoelectrical fiber that generates electric fields when it is moved. This fiber is designed with two layers: a core and a sheath. When the wound area moves, the contact between the layers changes, creating electrical signals. Research has shown that these electric fields can speed up healing by stimulating cell movement and tissue regeneration.

Over the past month, Dr. Horgan and his colleagues at the University of California, San Diego (UCSD) have conducted over 20 minimally invasive surgeries using Apple’s mixed-reality headset, the Vision Pro. Released to the public in February, the device has largely struggled to make an impact in the commercial market. However, in certain fields like architecture and medicine, professionals are exploring its potential to revolutionize their practices.

Dr. Horgan, who leads the Center for the Future of Surgery at UCSD, believes that incorporating the Vision Pro into surgical procedures could significantly enhance effectiveness while reducing the risk of injury. He sees the technology as a potential game-changer for hospitals, particularly those in underserved areas that lack access to expensive specialty equipment. “This is a revolution that will touch more lives, thanks to broader accessibility,” he says, referencing his own groundbreaking surgical advancements from the early 2000s.
