Lactose molecular structure

submitted by: nsf
One of milk’s two sugars, lactose is not digestible in those lacking sufficient levels of lactase, which allows the body to metabolize that sugar. Certain parts of the world are reported to have higher incidences of lactose intolerance. NSFfunded Sarah Tishkoff at the University of Pennsylvania is studying the “gut microbiome” and its impact on nutritional status; such as its contribution to obesity, malnutrition and susceptibility to infectious disease. Her anthropologic study will...

Community College Innovation Challenge

submitted by: nsf

The National Science Foundation announces its Community College Innovation Challenge. The contest challenges community college students to propose innovative STEM-based (science, technology, engineering and mathematics) solutions to perplexing, real-world problems. Teams submitting top ideas receive professional coaching and cash prizes.

Sucrose molecular structure

submitted by: nsf
Sucrose is table sugar—that ubiquitous sweet white crystal that sweetens our tea, coffee and apple pies, yet is also the villain blamed for tooth decay and other health issues. Through its Biological Sciences Directorate, NSF has funded Brian Ayre from the University of North Texas who studied the way sucrose produced in plant leaves through photosynthesis moved to and affected plant tissues. Sucrose is transported to tissues that are growing or accumulating storage reserves that can...

Glucose molecular structure

submitted by: nsf
Glucose, the simplest sugar, can be found in plants and is absorbed into bloodstreams during digestion. While most of us can be blissfully ignorant of our exact blood sugar levels after scarfing a Snickers, people who have diabetes or physicians with seriously injured patients need technology that provides accurate blood glucose data. Gymama Slaughter, an NSF-funded engineer at the University of Maryland Baltimore County, has created a new wireless, implantable sensor to monitor blood...

Fructose molecular structure

submitted by: nsf
Fructose, or fruit sugar, is found in tree fruits, honey and berries, though you may know it from its corn-based origins as the common ingredient high-fructose corn syrup. NSF-funded researchers are also looking at plant sugars as a potential fuel source. While the idea of plant-based fuels as an alternative to fossil fuels has been around for a while, engineers are finding new ways of getting bigger bio-based yields more cheaply. Xianghong Qian, a chemical engineer at the University of...

Jellyfish swarms research in the Gulf of Mexico

NCAR study points to increase in unhealthy summertime ozone levels

submitted by: nsf

Local weather forecast warnings about unhealthy air could become much more common around the country. A recent scientific study by the National Center for Atmospheric Research warns of a whopping 70% increase in the number of days with unhealthy summertime ozone levels by the year 2050.

Alzheimer’s patients: A surprise finding in executive function

submitted by: nsf
Deborah Zaitchik says executive function measures for Alzheimer’s patients show staggering declines. Under a National Science Foundation-funded INSPIRE project, Harvard University psychologists Susan Carey and Deborah Zaitchik are studying how executive function influences the process of learning. Here, Zaitchik discusses differences between populations with strong and weak executive function. For more information visit:...
