Low-Cost Microscope from Stanford Takes Top Prize at DEBUT
BETHESDA, Md., Aug. 27, 2020 — A team from Stanford University has won the top prize at the National Institutes of Health’s ninth annual Design by Biomedical Undergraduate Teams (DEBUT) competition. The team's device, the onchoscope, is a low-cost microscope designed to diagnose onchocerciasis, also known as river blindness. The device is able to diagnose the disease more accurately than the current standard of care, and it can also be used to monitor the parasitic load over time to evaluate the effectiveness of
Imaging Plays Key Role in Coronavirus Fight
BALTIMORE, March 30, 2020 — Faced with a critical shortage of resources in heading off the rapid spread of COVID-19 (commonly called “coronavirus”) around the world, health care personnel will rely on imaging as a guide for where monitoring and treatment will be...
Study: OCT Could Aid Brain Tumor Removal
BALTIMORE, June 19, 2015 — Optical coherence tomography (OCT) holds promise for guiding surgeons as they operate on brain tumors and help them avoid removing healthy tissue. After identifying brain cancer's OCT signature, researchers at Johns Hopkins University have developed...
Stimulating Light Receptors Relaxes Blood Vessels
BALTIMORE, Nov. 17, 2014 — A blood vessel receptor that responds to light could aid more effective treatment of vascular diseases and other medical conditions. A team led by Johns Hopkins Medicine discovered the receptor, which causes blood vessels to relax in response to...
Lens-Free Microscopes Offer Real-Time Bio Imaging
Sep 5, 2014 — A totally different type of microscope will be much smaller and less complex than traditional microscopes, but more powerful. Two years ago, a customer handed Richard Stahl and the imec team a challenge: one year to develop a microscope that could...
Light to the Heart to Restore Healthy Beats
BALTIMORE, Aug. 29, 2013 — When a person’s heart slows or stops, the current practice is to jump-start it with a blast of electricity from a pacemaker or defibrillator. But a multi-university team aims to put an optogenetic twist on the procedure by replacing the violent jolt...
SMART Scalpel Gives Surgeons Superhuman Precision
BALTIMORE, Sept. 28, 2012 — A new "smart" surgical tool equipped with a specialized optical fiber sensor can compensate for almost imperceptible hand tremors by making hundreds of precise position corrections each second — fast enough to keep a surgeon’s hand on...
Fly Cells Follow Laser Light
BALTIMORE, June 25, 2010 — Scientists at Johns Hopkins report using a laser beam to activate a protein that makes a cluster of fruit fly cells act like a school of fish turning in social unison, following the lead of the one stimulated with light. The study of this unexpected...
Ultrasensitive sensor causes stir at show
PRINCETON, N.J. – A prototype laser spectroscopy platform developed by electrical engineers at Princeton University attracted a lot of attention when it was demonstrated during SPIE Photonics West 2010 in January. The sensor, a new development in wireless sensor...
Provost Picked for Power Post
BALTIMORE, Md., March 13, 2009 -- Johns Hopkins University Provost and electrical engineer Kristina M. Johnson will be nominated to serve as undersecretary of the Department of Energy, President Barack Obama announced yesterday. If confirmed by the Senate as expected, Johnson...
Room-Temperature SCs?
Jun 5, 2008 — Newly discovered iron-based high-temperature superconductors could pave the way for the development of superconductors that can operate at room temperature. "If superconductors could exist at room temperatures, the world energy crisis would be...
Microsystem Incubates Cells
BALTIMORE, Oct. 3, 2007 -- By integrating silicon microchip technology with a network of tiny fluid channels, some thinner than a human hair, engineers have developed a thumb-sized microincubator to culture living cells for lab tests. Researchers at The Johns Hopkins...
Laser Blasts Viruses in Blood
BALTIMORE, Md., Sept. 4, 2007 -- A walk in the park led to a new use for lasers: zapping viruses out of blood. The technique, which holds promise for disinfecting blood for transfusions, uses a low-power laser beam with a pulse lasting just fractions of a second. Johns Hopkins...
EDT Helps Abbreviate Protein Studies
BALTIMORE, Md., April 23, 3007 -- PhosphoMotif Finder, a publicly available database on the Web (www.hprd.org/PhosphoMotif_finder) that could speed the work of researchers around the world, is the result of a new technique that reads the makeup of proteins to identify nearly all...
Genetic Enhancements Make Mice See Red
BALTIMORE, Md., March 23, 2007 -- Researchers have transformed the limited color vision of mice by introducing a single human gene into a mouse chromosome. The gene codes for a light sensor that mice do not normally possess, and its insertion allowed the mice to see colors as never...
Nanobiotech Institute Draws From Diverse Team
BALTIMORE, Md., May 22, 2006 -- The Institute for NanoBioTechnology launched last week at Johns Hopkins University will strive for major advances in medicine by drawing on the expertise of more than 75 faculty members from such diverse disciplines as engineering, biology, medicine...
Cornell Builds Robot That Can Reproduce
May 11, 2005 — ITHACA, N.Y., May 11 -- Cornell University researchers announced today they have created a machine that can build copies of itself. The machine is just a proof of concept -- it performs no useful function except to self-replicate -- but the basic...
Johns Hopkins Technology to Guide Undersea Robot
Dec 11, 2003 — BALTIMORE, Md., Dec. 11 -- The robotic "brain" that will steer a new remotely operated vehicle through the deepest parts of the world's oceans will employ technology devised by engineers at The Johns Hopkins University (JHU). The Woods Hole...
Dr. Robot Makes Rounds at Johns Hopkins
Sep 15, 2003 — BALTIMORE, Sept. 15 -- It lacks the warm bedside manner of Marcus Welby or Dr. Kildare, but a high-tech robot being tested at The Johns Hopkins Hospital could be used to link patients with their physicians in a whole new way. Vaguely resembling a...
'Twinning' Phenomenon Found in Nanocrystalline Aluminum
Aug 7, 2003 — BALTIMORE, Md., April 7 -- Using a powerful electron microscope to view atomic-level details, researchers have discovered a "twinning" phenomenon in a nanocrystalline form of aluminum that was plastically deformed during lab experiments. The...
Imaging Technique Measures Brain Tumor Sodium Levels
May 1, 2003 — BALTIMORE, May 1 -- In what is believed to be a first-of-its-kind study, Johns Hopkins University researchers have used magnetic resonance imaging (MRI) to measure sodium concentrations in the cells of malignant brain tumors. Because growth of such...
