(University of Toronto Scarborough) Zinc plays a critical role in regulating how neurons communicate with one another, and could affect how memories form and how we learn.

The new research, in the current issue of Neuron, was authored by Xiao-an Zhang, now a chemistry professor at the University of Toronto Scarborough, and colleagues at MIT and Duke University.

(American Thoracic Society) Changes that occur in the airways of asthma patients are in part caused by the naturally occurring protein interleukin-13 (IL-13) which stimulates invasion of airway cells called fibroblasts, according to a study conducted by researchers at Duke University.

The study is the latest effort by researchers to better understand the processes that are involved in airway remodeling that can cause breathing difficulties in patients with asthma.

(Duke University) A tiny light source and sensors at the end of an endoscope may provide a more accurate way to identify pre-cancerous cells in the lining of the esophagus.

(Duke University) Long a staple of nature documentaries, the somewhat bizarre development of a grub-like pink marsupial embryo outside the mother's womb is curious in another way.

Duke University researchers have found that the developmental program executed by the marsupial embryo runs in a different order than the program executed by virtually every other vertebrate animal.

(University of Texas at Austin) Mutations in a gene known as "Fritz" may be responsible for causing human genetic disorders such as Bardet-Biedl syndrome, University of Texas at Austin developmental biologist John Wallingford and Duke University human geneticist and cell biologist Nicholas Katsanis have found.

Concerns are being raised about the validity of research done by a Duke University cancer scientist who recently was placed on leave while the school investigates whether he falsely claimed to be a Rhodes scholar....

(Duke University) Feasibility studies conducted by Duke University bioengineers have demonstrated that a robot -- without any human assistance -- can locate a man-made, or phantom, lesion in simulated human organs, guide a device to the lesion and take multiple samples during a single session.

(Duke University) A team of Duke University researchers and African colleagues will be studying strategies to curb the spread of malaria while protecting human and environmental health.

The work in regions where the potentially deadly, mosquito-borne disease occurs will be supported by a $2.2 million, four-year grant from the National Institutes of Health.
