UCLA scientists have developed advanced miniature 3D tumor organoid models that make it possible to study glioblastoma tumors in a setting that closely mirrors the human brain, shedding light on how the aggressive cancer interacts with surrounding brain cells and the immune system to become more invasive and resistant to therapy. The organoid models, described in two complementary studies published in Cell Reports, are built from human stem cells and recreate the complex mix of cell types found in the human brain. This approach allows researchers to directly observe how patient-derived tumors communicate with healthy brain tissue, revealing ...

A new study led by investigators from Mass General Brigham shows that a brain waste- “clean-up” system is influenced by intracranial pressure. The system, called the glymphatic system, was unrecognized until 2012 and helps circulate fluid and remove waste from the brain. Using magnetic resonance imaging (MRI), the research team found that changes in this fluid flow may help doctors better diagnose intracranial hypertension (IIH) less invasively and more reliably than with standard approaches currently ...

WASHINGTON, Jan. 27, 2026 — Concrete structures like roads and bridges require nondestructive testing methods to identify interior defects without destroying their structure. Most methods send sound waves into the material and capture the waves that echo back to create images of what’s inside and find defects. This process is similar to ultrasounds used to see inside the human body. But unlike human tissues, concrete contains a diversity of materials, including stone, clay, chalk, slate, iron ore, and sand, that scatter sound waves and make clear imaging difficult to obtain. In an article in Applied Physics ...

University of Liverpool researchers have discovered a way to host some of the most significant properties of graphene in a three‑dimensional (3D) material, potentially removing the hurdles for these properties to be used at scale in green computing. Graphene is famous for being incredibly strong, lightweight, and an excellent conductor of electricity and its applications range from electronics to aerospace and medical technologies. However, its two-dimensional (2D) structure makes it mechanically fragile and limits its use in demanding environments and large-scale applications. In a paper published today, a team of researchers have identified that 3D material, HfSn₂, ...

Sunbeams contain a lot of energy. But current technology for harvesting solar power doesn’t capture as much as it could. Now, in ACS Applied Materials & Interfaces, researchers report that gold nanospheres, named supraballs, can absorb nearly all wavelengths in sunlight — including some that traditional photovoltaic materials miss. Applying a layer of supraballs onto a commercially available electricity converter demonstrated that the technology nearly doubled solar energy absorption compared to traditional materials. Scientists are exploring materials that absorb light ...

Research by an interdisciplinary team from McGill University and Université Laval provides new insights into the links between social factors and cognitive health among aging adults. While previous research had found positive correlations between specific measures of social connectedness and a variety of health outcomes, this study appears to have been the first to create profiles aggregating multiple social factors and to see how those correlated with cognitive health in older adults, the researchers said. The team derived three social environment ...

With the development of brain-computer interface (BCI) technology, the application of electroencephalography (EEG) signals in motion decoding has been expanding. Traditional BCI decoding is primarily based on Cartesian coordinates, which are suitable for representing linear movements but less efficient for decoding rotational or circular movements. In contrast, polar coordinates provide a more natural and compact representation for circular movements by directly encoding angular information, making it more efficient for decoding rotational ...

Lipstick vines get their name from their bright red, tube-shaped flowers. But one member of this group of plants has lost its lipstick-like appearance— its flowers are shorter, wider, and yellowish green in color. It also attracts shorter-beaked birds than its crimson cousins do, and it’s found in different places. Scientists wanted to know how this plant evolved from its lipstick-like relatives. After observing birds visiting hundreds of plants and examining the plants’ DNA, the researchers found that the story of the green ...

More than a century after the Titanic sank, engineers still have hopes of someday creating “unsinkable” ships. In a step toward reaching that lofty goal, researchers at the University of Rochester’s Institute of Optics have developed a new process that turns ordinary metal tubes unsinkable—meaning they will stay afloat no matter how long they are forced into water or how heavily they are damaged. Chunlei Guo, a professor of optics and of physics and a senior scientist at URochester’s Laboratory ...

Now is a great time for anyone who's shopping for a used car to consider an electric vehicle, according to new research from the University of Michigan.

Piezoelectric actuators are widely used in precision positioning, micro/nano fabrication, and microrobotics due to their high precision, fast response, and compactness, yet their inherently limited stroke (typically ~1/1000 of their length) constrains broader applications. To extend travel, stepping actuation approaches—such as inchworm, ultrasonic, and stick-slip mechanisms—have been explored, with stick-slip attractive for its relatively simple structure and control. However, many stick-slip designs still struggle with bidirectional motion consistency and motion smoothness/linearity: particularly, parasitic-motion-based ...
