Approximately 40% of the European population are allergic to pollen, and their symptoms cause an estimated loss of 100 million school and workdays every year.
There are few scientific methods more elegantly simple than “just sprinkle it on top.” Researchers at Tohoku University and Nagoya University developed a fluorescent probe that can quickly show synapses, the connection points between brain cells.
Nerve cells are not just nerve cells. Depending on how finely we distinguish, there are several hundred to several thousand different types of nerve cells in the human brain, according to the latest calculations.
A new skin-like sensor developed by an international team led by researchers at Penn State could help doctors monitor vital signs more accurately, track healing after surgery and even help patients with bladder control issues.
The new implant carries a reservoir of glucagon that can be stored under the skin and deployed during an emergency — with no injections needed.
Gastrointestinal cancers remain among the most common forms of cancer. While endoscopy has become a cornerstone of cancer screening and diagnosis over the past two decades, the procedure still misses approximately 8% to 11% of tumors, due to visibility limitations. Now, researchers have developed a prototype imaging system that could significantly improve doctors’ ability to detect cancerous tissue during endoscopic procedures.
Georgia Tech engineers have created a pill that could effectively deliver insulin and other injectable drugs, making medicines for chronic illnesses easier for patients to take, less invasive, and potentially less expensive.
In combat zones and emergency rescues, rapid evacuation and treatment can mean the difference between life and death. But prolonged immobilization during transport poses another life-threatening risk: pressure injuries.
For over a century, surgeons performing delicate procedures have relied on stereoscopic microscopes to gain a sense of depth. These tools mimic human vision by presenting slightly different images to each eye, allowing the brain to perceive three-dimensional structures—a crucial aid when working with fragile blood vessels or intricate brain tissue. Despite modern upgrades like digital displays and video capture, today’s operating microscopes still depend on the same core principle: two views, interpreted by the human brain.
In recent years, the analysis of single-cell and spatial data has revolutionized biomedical research, making it possible to observe what happens in biological samples with an unprecedented level of detail. Interpreting this data, however, is not easy because different software offers different results which are hard to compare.
