PHILADELPHIA -- Major advances in materials science and nanotechnology promise to revolutionize electronic devices with unprecedented strength and conductivity, but those promises can’t be fulfilled if the devices can’t be consistently manufactured.
What if there were 65,000 people in the United States who, despite successfully completing their secondary education, had no hope for the future? There are.
Matt Blaze of the School of Engineering and Applied Science comments on federal use ofsecret devices for locating people via cellphones.
Philadelphia - The possibility that anesthesia and surgery produces lasting cognitive losses has gained attention over past decades, but direct evidence has remained ambiguous and controversial. Now, researchers at the Perelman School of Medicine at the University of Pennsylvania provide further evidence that Alzheimer's pathology may be increased in patients after surgery.
Rebooting the System: Immune Cells Repair Damaged Lung Tissues after Flu Infection, Penn Study Finds
There’s more than one way to mop up after a flu infection. Now, researchers from the Perelman School of Medicine at the University of Pennsylvania report this week in Nature Immunology that a previously unrecognized population of lung immune cells orchestrate the body’s repair response following flu infection.
John Gearhart and George Costarelis of the Perelman School of Medicine comment on stem cell treatments.
PHILADELPHIA -- The United States has the highest prevalence of obesity, measured by body mass index, and one of the lowest life expectancies among high-income countries. A new study by researchers at the University of Pennsylvania directly links America’s high obesity rate to the country’s lower longevity ranking compared to other high-income countries.
PHILADELPHIA – As nocturnal animals, bats rely echolocation to navigate and hunt prey. By bouncing sound waves off objects, including the bugs that are their main diet, bats can produce an accurate representation of their environment in total darkness. Now, researchers at the University of Southern Denmark and the University of Pennsylvania have shown that this amazing ability is enabled by a physical trait never before seen in mammals: so-called “superfast” muscles.
PHILADELPHIA — One of the aims of cognitive neuroscience is to understand how the brain works on two distinct levels: the psychological experience of mental tasks and the underlying neurobiology that enables them. Tools like functional magnetic resonance imaging, or fMRI, have allowed cognitive neuroscientists to connect those two levels for a variety of everyday experiences, such as solving a math problem or remembering a word.
