Scientists find you can be distracted by something totally worthless if that something was once associated with a reward. The results have implications for understanding how the brain responds to rewards, which may contribute to more effective treatments for drug addiction, obesity and ADHD.
Computer experiments reveal that, in principle, two identical small beads dropped into the same turbulent flow at precisely the same starting location will end up at different – and entirely random – destinations.
How human children acquire language remains largely a mystery. A groundbreaking study by cognitive scientists at The Johns Hopkins University confirms that human beings are born with knowledge of certain syntactical rules that make learning human languages easier.
The older we get, the more difficulty we seem to have remembering things. We reassure ourselves that our brains' "hard drives" are too full to handle the new information that comes in daily. But a Johns Hopkins neuroscientist suggests that our aging brains are unable to process this information as "new" because the brain pathways leading to the hippocampus become degraded over time. As a result, our brains cannot accurately "file" new information.
Follow along online as Johns Hopkins University Egyptologist Betsy Bryan and her team of students, artists, conservators and photographers return to their investigation of Mut Temple this month, focusing their attention to the area south of the temple's Sacred Lake. Bryan and her crew are resuming their excavation in Luxor, Egypt, and are sharing their work via "Hopkins in Egypt Today," their popular digital diary offering a virtual window into day-to-day life on an archaeological dig.
Cold-formed steel has become a popular construction material for commercial and industrial buildings, but a key question remains: How can these structures be designed so that they are most likely to remain intact in a major earthquake?
An expert on how light – or lack thereof – affects biological clocks and health, biologist Samer Hattar can discuss the likely impact that 69 days without natural light had on the Chilean miners’ physiology.
Rod cells – one of three kinds of exquisitely photosensitive cells found in the retina of the eye – are surprisingly found to be the only ones responsible for “setting” our internal clocks in low light.
Scientists want to provide the users of prosthetic limbs the ability to feel what they are touching or experience the comforting perception of holding hands.
Nonprofit employers are providing one of the few bright spots in the country's dismal employment picture this Labor Day, according to new data released today by researchers at the Johns Hopkins University Center for Civil Society Studies.
A website that brings the universe into the homes and onto the computer screens of professional and amateur astronomers alike has won a major prize from the American Association for the Advancement of Science.
A common form of dwarfism is caused by a single genetic mutation. If a scientist could figure out precisely how this errant protein causes trouble, then a way to prevent the condition might be found. Sounds like a job for a biologist. But what about an engineer?
Johns Hopkins researchers are part of a multi-institution team formed to determine how the Deepwater Horizon Gulf of Mexico oil spill affects a sensitive aquatic environment off the coast of Florida.
Research finds that mice without working rods and cones can still see -- and not just light, but also patterns and images -- thanks to other photosensitive cells in the retina.
Researchers use precise electrical “tweezers” to place nanowires on predetermined spots on single cells. The technique eventually could produce new ways to deliver medication.
Showing movies in 3-D has produced a box-office bonanza in recent months. Could viewing cell behavior in three dimensions lead to important advances in cancer research?
If you think summer in your hometown is hot, consider the Turkana Basin of Kenya, where the average daily temperature has reached the mid-90s or higher, year-round, for the past 4 million years. Could the climate have influenced the way humans evolved in that region?
Edward J. Bouwer of Johns Hopkins University is an expert on environmental damage, oil biodegradation, prospects for recovery and cleanup options, including the use of bacteria that consume oil.
Reporters who are looking for a expert perspective on President Obama's nomination of Elena Kagan to the Supreme Court should consider Johns Hopkins University Professor Joel Grossman.
If you're looking for an expert to put the career and legacy of John Paul Stevens into perspective — as well as someone who can talk about what happens next and how the high court will likely change — consider Johns Hopkins University Professor Joel Grossman.
A Johns Hopkins team has won a $5 million NSF grant to probe what happened during the universe’s first trillionth of a second, when it suddenly grew from submicroscopic to astronomical size in far less than time than it takes to blink your eye.
Johns Hopkins researchers have developed a noninvasive infrared scanning system to help doctors determine whether pigmented skin growths are benign moles or melanoma, a lethal form of cancer.
Researchers have discovered that, under the right conditions, newly developed nanocrystalline materials exhibit surprising activity in the tiny spaces between the geometric clusters of atoms called nanocrystals from which they are made.
A microbe commonly found in the Chesapeake Bay and other waterways emits a poison not just to protect itself but to stun and immobilize the prey it plans to eat.
Experts for stories relating to health care in Haiti, disaster relief, earthquake engineering, water quality, historical and political perspectives on Haiti and other issues.
Researchers have created biodegradable nanosized particles that can easily slip through the body’s sticky and viscous mucus secretions to deliver a sustained-release medication cargo.
Biomedical engineers have produced a laboratory chip with nanoscopic grooves and ridges capable of growing cardiac tissue that closely resembles natural heart muscle.
Materials scientists have found a way to transform a chemical long used as an electrical conductor a thin film insulator potentially useful in transistor technology and in devices such as electronic books.
As an electrical engineer, Jin U. Kang has spent years tinkering with lasers and optical fiber, studying what happens when light strikes matter. Now, he’s taking on a new challenge: brain surgery.
Researchers from the Johns Hopkins Institute for NanoBioTechnology have been awarded $14.8 million from the National Cancer Institute to launch a research center aimed at unraveling the physical underpinnings of the growth and spread of cancer.
Using data from Hurricane Katrina and four other destructive storms, researchers have found a way to accurately predict power outages in advance of a hurricane.
Johns Hopkins engineers have devised innovative computer software that can sift through hundreds of genetic mutations and highlight the DNA changes that are most likely to promote cancer.

Johns Hopkins engineers are using a popular children’s toy to visualize the behavior of particles, cells and molecules in environments too small to see with the naked eye. These researchers are arranging little LEGO pieces shaped like pegs to re-create microscopic activity taking place inside lab-on-a-chip devices at a scale they can more easily observe.
Using tiny crystals called quantum dots, Johns Hopkins researchers have developed a highly sensitive test to look for DNA attachments that often are early warning signs of cancer.
A larger proportion of immigrant black high school graduates attend selective colleges and universities than both native black and white students in America, according to a study by sociologists at Johns Hopkins University and Syracuse University.
Reporters who are looking for expert perspectives on newly confirmed Supreme Court Justice Sonia Sotomayor should consider Johns Hopkins University lecturer Adam Segal, director of the Hispanic Voter Project, and Joel Grossman, professor of political science.
