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.

Four fledgling companies have already moved into the building.
When a solar flare filled with charged particles erupts from the sun, its magnetic fields sometime break a widely accepted rule of physics. The flux-freezing theorem dictates that the magnetic lines of force should flow away in lock-step with the particles, whole and unbroken. Instead, the lines sometimes break apart and quickly reconnect in a way that has mystified astrophysicists. But in a paper published in the May 23 issue of the journal Nature, an interdisciplinary research team led by a Johns Hopkins mathematical physicist says it has found a key to the mystery.
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.
It’s a parent’s worst nightmare: a young child is accidentally left in a locked car on a warm and sunny day. The closed windows turn the car into a greenhouse, and the child dies of heatstroke. In a key first step toward preventing such tragedies, three undergraduate engineering students at Johns Hopkins have turned technology from a popular video game player into a detector for children left behind in dangerously overheated vehicles.
More than 100 Baltimore City Public middle and high school students will compete in the Hopkins Robotics Cup, the first Baltimore City VEX Robotics Championship, from 9 a.m. to 5 p.m. on Saturday, May 4, in the Newton White Athletic Center on The Johns Hopkins University’s Homewood campus.
More than a dozen student teams from the Baltimore area will bring small autonomous robots to compete in various events during the competition, organized by Johns Hopkins graduate students from the university’s Laboratory for Computational Sensing and Robotics. Contest events include slalom racing, mystery maze navigation, “tumor” detection, robot dancing and innovative use.
By using swarms of untethered grippers, each as small as a speck of dust, Johns Hopkins engineers and physicians say they have devised a new way to perform biopsies that could provide a more effective way to access narrow conduits in the body as well as find early signs of cancer or other diseases. In two recent peer-reviewed journal articles, the team reported successful animal testing of the tiny tools, which require no batteries, wires or tethers as they seize internal tissue samples.
Three undergraduate researchers at The Johns Hopkins University are among the 271 students recently awarded Goldwater Scholarships for the 2013-2014 academic year. The one- and two-year funding the three Johns Hopkins students receive will help further their investigations in molecular dynamics, the biomedical science of disease, and developing a computational tool to help surgeons treat epilepsy.
Could algae that feast on wastewater produce clean bio-fuels and a healthful supply of fish food? Can impoverished African community gardeners learn to use and maintain a simple centuries-old, non-electric water pump to grow more vegetables? Two Johns Hopkins student teams are working hard to move these “green” ideas off the drawing board and into the real world. Both teams will showcase their progress at the 2013 National Sustainable Design Expo, scheduled April 18 and 19, in Washington, D.C. The event, which will be open to the public on the National Mall, is sponsored by the U.S. Environmental Protection Agency
Johns Hopkins Business Plan Competition presentations and judging will take place from 1:30 to 5 p.m. on Friday, April 12. Twenty-four finalist teams will present their business plans to judges in three categories: medical technologies and life sciences, general business and social enterprise. Each team is composed of two to 10 undergraduates, graduate students or post-doctoral fellows who have devised a product or service they propose to sell. The finalist teams come from seven Johns Hopkins University divisions.
When babies are deprived of oxygen before birth, brain damage and disorders such as cerebral palsy can occur. Extended cooling can prevent brain injuries, but this treatment is not always available in developing nations where advanced medical care is scarce. To address this need, Johns Hopkins undergraduates have devised a low-tech $40 unit to provide protective cooling in the absence of modern hospital equipment that can cost $12,000.
Concussions can occur in sports and in combat, but health experts do not know precisely which jolts, collisions and awkward head movements during these activities pose the greatest risks to the brain. To find out, Johns Hopkins engineers have developed a powerful new computer-based process that helps identify the dangerous conditions that lead to concussion-related brain injuries. This approach could lead to new medical treatment options and some sports rule changes to reduce brain trauma among players.
Sudoku has become a worldwide craze, with everyone from middle school students to grandmothers sitting down with sharpened pencil and a puzzle several times a week. Many of the newspapers and magazines that publish Sudoku assure readers that the puzzles have nothing to do with mathematics. But that is simply not true, according to a James Madison University mathematics professor who is coming to Johns Hopkins University in early March to deliver a lecture on that topic.
A Johns Hopkins engineer who is designing cancer-fighting nano-size structures that could assemble themselves and deliver treatment to diseased tissue has received a Faculty Early Career Development (CAREER) Award from the National Science Foundation. Honggang Cui, an assistant professor in the Department of Chemical and Biomolecular Engineering at Johns Hopkins, has been given this honor, which is accompanied by nearly $500,000 that will be disbursed over five years.
As asteroid 2012 DA14 squeaks by Earth, professors at The Johns Hopkins University are available to discuss what we can do to prepare for – or even prevent – such close encounters in the future.
A Johns Hopkins engineer who is developing a high-speed imaging system designed to enable researchers to continuously record images at a rate of more than 100 million frames per second – 100 times more rapidly than current technology allows – has been awarded the National Science Foundation’s prestigious Faculty Early Career Development (CAREER) Award, a five-year, $400,000 grant.

With the 2013 Super Bowl less than two weeks away and his hometown Baltimore Ravens raring to go, Johns Hopkins math expert Daniel Naiman has run the numbers. He found that his favorite team faces some tough odds but also has some upbeat history on its side.
Sifting through social media messages has become a popular way to track when and where flu cases occur, but a key hurdle hampers the process: how to identify flu-infection tweets. Some tweets are posted by people who have been sick with the virus, while others come from folks who are merely talking about the illness. If you are tracking actual flu cases, such conversations about the flu in general can skew the results. To address this problem, Johns Hopkins computer scientists and researchers in the School of Medicine have developed a new tweet-screening method that not only delivers real-time data on flu cases, but also filters out online chatter that is not linked to actual flu infections.
