Without prompt care, a badly wounded soldier can easily bleed to death while being transported to a distant medical station. Two traditional treatments—tourniquets and medicated gauze pads—often cannot stop the blood loss from a deep wound at the neck, shoulder or groin. To give these soldiers a fighting chance at survival, Johns Hopkins undergraduates have invented an injectable foam system designed to stop profuse bleeding from a wound where a limb or the head is connected to the torso.

Robert J. Johnston, a biologist at The Johns Hopkins University, studying how cells randomly choose their fates during development and Andrew J. Holland, a molecular biologist at the university’s School of Medicine, whose work focuses on how dividing cells create the correct number of centrosomes, have been named Pew scholars for their promising work in the area of health sciences.
Benjamin Langmead, assistant professor in the Department of Computer Science at Johns Hopkins University’s Whiting School of Engineering, has been chosen by the National Science Foundation to receive its prestigious CAREER Award, which recognizes the high level of promise and excellence in early-stage scholars.
Johns Hopkins biomedical engineering students have designed a lightweight, easy-to-conceal shirt-like garment to deliver life-saving shocks to patients experiencing serious heart problems. The students say their design improves upon a wearable defibrillator system that is already in use. Their design changes, the students say, should help persuade patients at risk for sudden cardiac arrest to wear the system around the clock.
Minimizing a person’s sight for as little as a week may help improve the brain’s ability to process hearing, neuroscientists have found.
When an MRI scan uncovers an unusual architecture or shape in a child’s brain, it’s cause for concern: The malformation may be a sign of disease. But deciding whether that odd-looking anatomy is worrisome or harmless can be difficult. To help doctors reach the right decision, Johns Hopkins researchers are building a detailed digital library of MRI scans collected from children with normal and abnormal brains. The goal, the researchers say, is to give physicians a Google-like search system that will enhance the way they diagnose and treat young patients with brain disorders.
Johns Hopkins Students Win Inventors Contest’s Top Prizes for Heart Treatment Device and Cancer Test
A Johns Hopkins undergraduate biomedical engineering student team that devised a two-part system to improve the way life-saving shocks are delivered to hearts earned first-prize in the undergraduate division of a national Collegiate Inventors Competition. In the graduate-level competition, Isaac Kinde, a Johns Hopkins medical student, received third-place honors for developing a test to detect ovarian and endometrial cancers as part of a team at the Johns Hopkins Kimmel Cancer Center.
Johns Hopkins engineers and cardiology experts have teamed up to develop a fingernail-sized biosensor that could alert doctors when serious brain injury occurs during heart surgery. By doing so, the device could help doctors devise new ways to minimize brain damage or begin treatment more quickly. In the Nov. 11 issue of the journal Chemical Science, the team reported on lab tests demonstrating that the prototype sensor had successfully detected a protein associated with brain injuries.
Two Johns Hopkins faculty members–Natalia Trayanova and Hans Tomas Bjornsson–have been chosen to receive prestigious National Institutes of Health grants allocated for biomedical research projects that face significant challenges but could lead to major health care payoffs. The Johns Hopkins researchers are among 78 grant recipients nationwide announced Sept. 30 under the High Risk-High Reward Program supported by the National Institutes of Health Common Fund.
Five Johns Hopkins graduate students, recently named to the 2014 class of Siebel Scholars, are pushing the boundaries of medical technology to develop new and improved ways to diagnose and treat cancer, heart disease and other serious health problems. The students are trying to turn stem cells into healthy blood vessels, are testing biological reactions within microscopic droplets and are using advanced imaging techniques to detect disease at an early, treatable stage.
In recognition of their research skills, academic achievements and leadership qualities, the five PhD candidates are being honored as Johns Hopkins’ 2014 Siebel Scholars. The merit-based Siebel program provides $35,000 to each student for use in his or her final year of graduate studies.
When a beating heart slips into an irregular, life-threatening rhythm, the treatment is well known: deliver a burst of electric current from a pacemaker or defibrillator. But because the electricity itself can cause pain, tissue damage and other serious side-effects, a Johns Hopkins-led research team wants to replace these jolts with a kinder, gentler remedy: light. In a paper published Aug. 28 in the online journal Nature Communications, five biomedical engineers from Johns Hopkins and Stony Brook universities described their plan to use biological lab data and an intricate computer model to devise a better way to heal ailing hearts.
Johns Hopkins Researchers Find Sympathetic Neurons Engage in “Cross Talk” With Cells in the Pancreas During Early Development
The human body is a complicated system of blood vessels, nerves, organs, tissue and cells each with a specific job to do. When all are working together, it’s a symphony of form and function as each instrument plays its intended roles. Biologist Rejji Kuruvilla and her fellow researchers uncovered what happens when one instrument is not playing its part.
Johns Hopkins Receives Grant From Medtronic for Student Engineering Program Focused on Medical Devices for Developing Countries
Medtronic, one of the world’s largest medical technology companies, has entered into an innovative partnership with The Johns Hopkins University, agreeing to provide $200,000 a year for up to three years and skilled mentoring to help biomedical engineering students design new healthcare solutions for underserved patients in developing countries.
Imagine millions of jigsaw puzzle pieces scattered across a football field, with too few people and too little time available to assemble the picture. Scientists in the new but fast-growing field of computational genomics are facing a similar dilemma. In recent decades, these researchers have begun to assemble the chemical blueprints of the DNA found in humans, animals, plants and microbes, unlocking a door that will likely lead to better healthcare and greatly expanded life-science knowledge. But a major obstacle now threatens the speedy movement of DNA’s secrets into research labs, two scholars in the field are warning.
Biophysics Research for Baltimore Teens, a paid summer internship program, aims to give city high school students from low-income communities a head start in science careers by exposing them to the thrills of university-level bio-medical lab work.
When a breast tumor is detected, many women opt to have a lumpectomy, which is surgery designed to remove the diseased tissue while preserving the breast. But during this procedure, doctors cannot learn right away whether all of the cancerous tissue has been removed, with no microscopic signs that cancer cells were left behind. Because of this delay, one in five of these women—up to 66,000 patients annually in the U.S. alone—must return for a second surgery to remove remaining cancer. These follow-up operations boost healthcare costs and can lead to delays in receiving other treatments such as radiation and chemotherapy. To reduce the need for these second surgeries, four Johns Hopkins graduate students have designed a device to allow pathologists to quickly inspect excised breast tissue within 20 minutes, while the patient is still in the operating room.
Johns Hopkins student-built devices—a blood clot detection system and a concealable, hands-free breast pump—have won two of the top three awards in a national contest that recognizes innovative biomedical engineering designs that have high commercial potential and social impact.
A team of students at the Johns Hopkins University’s Whiting School of Engineering has designed for NASA a new stethoscope that delivers accurate heart- and body-sounds to medics who are trying to assess astronauts’ health on long missions in noisy spacecraft.
