When you were a kid, did you ever sign a classmate’s cast after they broke an arm or a leg? Your name would be on display there for the rest of the semester. Broken bones are one of the worst trade-offs in childhood—a few seconds of calamity followed by months of boring rest and recovery. But children in the future may have a different story to tell as emerging tech overhauls how we fix broken bones.
Carbon nanomaterials may have the power to heal bones faster than a Harry Potter fan can say ‘Brackium Emendo!’ Researchers from Stefanie A. Sydlik’s team at Carnegie Mellon University have tested a new formulation of graphene that is biodegradable, mimics bone, attracts stem cells, and ultimately improves how animals can repair damage to their skeletons.
As reported in PNAS, this phosphate graphene serves as a scaffold, allowing the body’s own cells to more rapidly reform the missing or damaged bone. The technique has already shown success in mice. As this technology matures it could become a vital part of orthopedic medicine, helping us recover faster with stronger, healthier bones.

The Stunning New Push to Protect the Invisible 99% of Life
Scientists worldwide have joined forces to build the first-ever roadmap for conserving Earth’s vast invisible majority—microbes. Their new IUCN Specialist Group reframes conservation by elevating microbial life to the same urgency as plants and [...]
Scientists Find a Way to Help the Brain Clear Alzheimer’s Plaques Naturally
Scientists have discovered that the brain may have a built-in way to fight Alzheimer’s. By activating a protein called Sox9, researchers were able to switch on star-shaped brain cells known as astrocytes and turn them into [...]
Vision can be rebooted in adults with amblyopia, study suggests
Temporarily anesthetizing the retina briefly reverts the activity of the visual system to that observed in early development and enables growth of responses to the amblyopic eye, new research shows. In the common vision [...]
Ultrasound-activated Nanoparticles Kill Liver Cancer and Activate Immune System
A new ultrasound-guided nanotherapy wipes out liver tumors while training the immune system to keep them from coming back. The study, published in Nano Today, introduces a biodegradable nanoparticle system that combines sonodynamic therapy and cell [...]
Magnetic nanoparticles that successfully navigate complex blood vessels may be ready for clinical trials
Every year, 12 million people worldwide suffer a stroke; many die or are permanently impaired. Currently, drugs are administered to dissolve the thrombus that blocks the blood vessel. These drugs spread throughout the entire [...]
Reviving Exhausted T Cells Sparks Powerful Cancer Tumor Elimination
Scientists have discovered how tumors secretly drain the energy from T cells—the immune system’s main cancer fighters—and how blocking that process can bring them back to life. The team found that cancer cells use [...]
Very low LDL-cholesterol correlates to fewer heart problems after stroke
Brigham and Women's Hospital's TIMI Study Group reports that in patients with prior ischemic stroke, very low achieved LDL-cholesterol correlated with fewer major adverse cardiovascular events and fewer recurrent strokes, without an apparent increase [...]
“Great Unified Microscope” Reveals Hidden Micro and Nano Worlds Inside Living Cells
University of Tokyo researchers have created a powerful new microscope that captures both forward- and back-scattered light at once, letting scientists see everything from large cell structures to tiny nanoscale particles in a single shot. Researchers [...]
Breakthrough Alzheimer’s Drug Has a Hidden Problem
Researchers in Japan found that although the Alzheimer’s drug lecanemab successfully removes amyloid plaques from the brain, it does not restore the brain’s waste-clearing system within the first few months of treatment. The study suggests that [...]
Concerning New Research Reveals Colon Cancer Is Skyrocketing in Adults Under 50
Colorectal cancer is striking younger adults at alarming rates, driven by lifestyle and genetic factors. Colorectal cancer (CRC) develops when abnormal cells grow uncontrollably in the colon or rectum, forming tumors that can eventually [...]
Scientists Discover a Natural, Non-Addictive Way To Block Pain That Could Replace Opioids
Scientists have discovered that the body can naturally dull pain through its own localized “benzodiazepine-like” peptides. A groundbreaking study led by a University of Leeds scientist has unveiled new insights into how the body manages pain, [...]
GLP-1 Drugs Like Ozempic Work, but New Research Reveals a Major Catch
Three new Cochrane reviews find evidence that GLP-1 drugs lead to clinically meaningful weight loss, though industry-funded studies raise concerns. Three new reviews from Cochrane have found that GLP-1 medications can lead to significant [...]
How a Palm-Sized Laser Could Change Medicine and Manufacturing
Researchers have developed an innovative and versatile system designed for a new generation of short-pulse lasers. Lasers that produce extremely short bursts of light are known for their remarkable precision, making them indispensable tools [...]
New nanoparticles stimulate the immune system to attack ovarian tumors
Cancer immunotherapy, which uses drugs that stimulate the body’s immune cells to attack tumors, is a promising approach to treating many types of cancer. However, it doesn’t work well for some tumors, including ovarian [...]
