Medina-Serpas et al. provide a public spatial transcriptomic atlas of pancreas and pLN comprising defined stages of human T1D. Cross-platform validation revealed pancreatic inflammation and elevated lymphotoxin-β expression as a signature of T1D, persistent across tissues. These data support therapeutic targeting of the lymphotoxin/TNF pathway in T1D.
These individuals consistently perform on memory tests at levels similar to people at least 30 years younger, challenging the long-standing belief that cognitive decline is unavoidable with age.
Over decades of research, scientists have noticed some lifestyle and personality traits that set SuperAgers apart from their peers, including being highly social and outgoing. Still, the most surprising discoveries have come from examining their brains. “It’s really what we’ve found in their brains that’s been so earth-shattering for us,” said Dr. Sandra Weintraub, a professor of psychiatry and behavioral sciences and neurology at Northwestern University Feinberg School of Medicine.
By identifying both biological and behavioral patterns linked to SuperAging, researchers hope to develop new approaches to strengthen cognitive resilience and reduce the risk of Alzheimer’s disease and other forms of dementia.
During cell division, faithful chromosome segregation is ensured by the mitotic spindle. van Toorn et al. uncovered that Cdk1-mediated phosphorylation of the dynein-activating adaptor NuMA promotes the timely assembly of dynein/dynactin/NuMA complexes, essential for correct mitotic progression and genome integrity.

New technology enables the insertion of a large segment of DNA into a genome, potentially expanding gene therapy treatment from cancellation of disease-causing mutations to replacement of an entire gene, scientists say.
Reporting in Nature, the researchers describe building upon a technique called prime editing by inserting DNA that attaches to the genome through a series of overlapping flaps. This method, which they call a prime assembly approach, avoids a bottleneck in the gene therapy field—a double-strand break to the donor DNA that can cause toxicity and kill cells.
“Using this method, we are doing genome assembly rather than making a small edit in a gene,” said Bin Liu, a co-lead author of the study and assistant professor of biological chemistry and pharmacology at The Ohio State University College of Medicine. “If we think of the genome as a book, we can remove one paragraph and replace it with a new one—or even rewrite a chapter.”
In the increasingly digital world, the demand for faster, more efficient and miniaturized optical devices is ever-growing. From high-speed internet and secure quantum communications to advanced medical imaging and precision manufacturing, the backbone of these technologies is light, specifically how we can control and manipulate it at the nanoscale.
Two-dimensional (2D) materials have emerged as a game-changer in this arena, offering unique properties that can be harnessed for ultrafast photonics and nonlinear optical applications.
However, the search for materials that combine stability, tunability and high performance in the near-infrared (NIR) region, a crucial window for telecommunications and sensing, remains a significant challenge.
Researchers have developed tiny flexible lasers that can be used to measure forces inside living cells. The new lasers could help illuminate various biological processes, including those involved in early development and tumor progression.
“Biological forces inside and between cells play an important role in many diseases,” said research team leader Marcel Schubert from the University of Cologne. “For example, when cancer cells invade tissue, they have to squeeze through the other cells. Our tiny lasers make it possible to measure forces on the scale of individual cells, which has previously been very difficult to accomplish.”
In the journal Optical Materials Express, the researchers describe their new spherical whispering gallery mode microbead lasers, which measure just 20 microns, about the width of a human hair. Whispering gallery mode lasers trap light in circular paths—in this case, inside a tiny elastomer bead doped with fluorescent dye—where the light circulates and amplifies until it emits coherent laser light.
Researchers at Tampere University have recently demonstrated that light can be used to precisely reshape soft materials without mechanical contact. They have developed light-responsive hydrogel thin films that enable programmable surfaces with high sensitivity, rapid response, precise spatial control and reversibility. The technology opens new possibilities for tunable devices in photonics, sensing and biomedicine.
Until now, responses in hydrogel films have typically been limited to timescales of tens of seconds and spatial resolutions of tens of micrometers—about the thickness of a fine human hair—restricting practical applications. In contrast, the university’s Smart Photonic Materials research group has achieved control on sub-second timescales and sub-micron resolution, marking a significant advance in speed and precision. The findings are published in the journal Nature Communications.
Light-responsive hydrogels are particularly attractive for mimicking dynamic microstructures found in nature. The materials absorb and release water when exposed to light, enabling accurate and remote actuation in lightweight structures. Such properties are well suited for applications including soft micro-robots, remote drug delivery systems and active cell culture platforms.
More academic and nonprofit labs should act as spinoff factories — both creating innovative foundational technologies *and* pushing these technologies forward towards the entrepreneurial translation needed to truly change the world for the better.
A research university emphasizes entrepreneurial science—and spawns start-ups in fields as varied as genetic medicine, humanoid robotics and carbon-catching materials.
