Why Doctors Say OpenEvidence Is A ‘Game Changer’

What is Open Evidence? It is a chatbot specialized for doctors to use to help speed up their work. 50 percent of all American doctors so far are signed up for it.

Chatbots, when utilized properly have great potential to help in the field.

From oncology to cardiology, AI platform OpenEvidence is helping physicians keep pace with medical breakthroughs while focusing on their patients. The software is used by around half of all American doctors, and is proving a game changer for physicians.

Groove Quantum Demonstrates 18-Qubit Spin Processor and Secures Funding

PRESS RELEASE — Groove Quantum today announced it has raised €16 million in combined funding and demonstrated an 18-qubit semiconductor spin-qubit processor, the largest of its kind ever built. The result marks a step beyond small-scale laboratory prototypes toward a quantum processor architecture designed for large-scale integration. The combined funding consists of €10 million in equity and €6 million in grants. The equity seed round is co-led by Innovation Industries, a leading European deep tech fund, and 55 North, the world’s largest pure-play quantum fund, with participation from Verve Ventures and the European Innovation Council Fund. Additional funding is provided by grants from the EIC Accelerator programme and JU Chips Act funding programme further underscores institutional confidence in Groove’s approach.

Groove will use the capital to scale qubit count exponentially and to begin manufacturing its processors at established semiconductor foundries.

Quantum computers create a fundamentally new way of computing. This opens the door to solving complex challenges that would take today’s most powerful supercomputers impractically long to address, like the discovery of new medicines, and the design of advanced materials for renewable energy – challenges that are highly important and have a profoundly positive impact on humanity.

Spatial transcriptomics from pancreas and local draining lymph node tissue reveals a lymphotoxin-β signature in human type 1 diabetes

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 80-year-olds have the memory of 50-year-olds. Scientists now know why

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.

A multifaceted kinase keeps molecular motors in place for faithful cell division

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 genome editing method could swap entire genes and correct 1000 mutations at once

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.”

A new era for ultrafast photonics: 2D mercury-acetylide frameworks for near-infrared nonlinear optics

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.

Tiny flexible lasers enable force sensing inside living cells

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.
