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.
Scientists take the next step in next step in understanding how the brain compresses huge "files" of visual information down to the essentials.
For more efficient power generation, operators of large wind farms should space their turbines farther apart.
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.

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?
Fish really is “brain food.” And it seems that even pre-humans living as far back as 2 million years ago somehow knew it.
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?
Pre-humans living in East Africa 4.4 million years ago inhabited grassy plains, not forests, a team of researchers has concluded.
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.
