Patients seek revision plastic surgery to correct asymmetric nasal tips, breathing obstructions

Patients who seek a second surgery to revise their rhinoplasty often do so because they are dissatisfied with the symmetry of their nasal tip and because they experience nasal obstructions, according to a report in the September/October issue of Archives of Facial Plastic Surgery, one of the JAMA/Archives journals. Surgeons who examine revision rhinoplasty candidates cite slightly different findings than patients, suggesting that communication about nasal aesthetics could be improved. Approximately 5 percent to 15 percent of patients who have rhinoplasty [plastic surgery ...

For neurons to work as a team, it helps to have a beat

Berkeley — When it comes to conducting complex tasks, it turns out that the brain needs rhythm, according to researchers at the University of California, Berkeley. Specifically, cortical rhythms, or oscillations, can effectively rally groups of neurons in widely dispersed regions of the brain to engage in coordinated activity, much like a conductor will summon up various sections of an orchestra in a symphony. Even the simple act of catching a ball necessitates an impressive coordination of multiple groups of neurons to perceive the object, judge its speed and trajectory, ...

Rotating high-pressure sodium lamps provide flowering plants for spring markets

EAST LANSING, MI—When consumers visit garden centers in spring they will most likely buy flowering ornamental plants that are ready for their home gardens. Studies have shown that consumers favor plants that are already in flower rather than those that are "vegetative"—a preference that can present multiple challenges for commercial growers. To satisfy consumers' wishes, producers of ready-to-flower ornamentals like bedding plants and perennials start growing crops far in advance of the spring buying season, often during the dark and short days of winter. When the days ...

NASA sees Tropical Storm Julia getting 'dusted'

Dust has been blowing into the Eastern Atlantic Ocean from Africa's Saharan Desert, and a NASA satellite captured some of that dust east of Tropical Storm Julia. NASA's Moderate Resolution Imaging Spectroradiometer (MODIS) instrument on the Terra satellite captured a visible image of Tropical Storm Julia on Sept. 18 at 13:50 UTC (9:50 a.m. EDT) and noticed a large area of Saharan dust over the Atlantic Ocean, to Julia's east. On Sept. 20 at 5 a.m. EDT, Julia was still holding on to tropical storm status with maximum sustained winds near 45 mph. Julia was located about ...

NASA satellites and aircraft studied Hurricane Karl before it faded

Hurricane Karl made landfall near Veracruz, Mexico on Friday, Sept. 17 and moved inland over Mexico's rugged terrain, which took the punch out of the storm. As Karl was moving into Mexico, NASA aircraft and NASA satellites were gathering data from this storm that jumped from a tropical storm to a Category 3 hurricane the day before. Karl had maximum sustained winds of 115 mph when it made landfall on Friday afternoon, Sept. 17. That made Karl a Category three hurricane on the Saffir-Simpson scale, and a major hurricane to boot. On that day, NASA's Genesis and Rapid ...

Food for thought, er, well...

Ever wonder why it's such an effort to forget about work while on vacation or to silence that annoying song that's playing over and over in your head? Mathematicians at Case Western Reserve University may have part of the answer. They've found that just as thinking burns energy, stopping a thought burns energy - like stopping a truck on a downhill slope.

Low-calorie cheesecake? Why we have trouble estimating calories

When it comes to estimating calorie counts, Americans aren't really on the ball. According to a new study in the Journal of Consumer Research, this may be because of the order in which we encounter the food. "The sequence in which items are considered often influences our evaluations of these items," writes author Alexander Chernev (Northwestern University). "The focus on sequential estimation is important because many meals are ordered and consumed sequentially rather than at once. Moreover, to control their daily calorie intake, people often estimate not only the amount ...

Scientists uncover process enabling toxoplasmosis parasite to survive homelessness

INDIANAPOLIS — The parasite responsible for toxoplasmosis requires a stress response system that helps it survive the move to infect new cells, Indiana University School of Medicine scientists have reported, a discovery that could lead to new treatments to control the disease. Parasites such as Toxoplasma gondii invade host cells, replicate and then must exit to find new host cells to invade. Traveling outside their host cell exposes the parasites to environmental stresses that limit how long they can remain viable while searching for new host cells. The researchers ...

Learning how consumers value products

Suggesting to consumers that they will use a product frequently can actually reduce their interest in purchasing the product, according to a new study in the Journal of Consumer Research. "When consumers estimate the value of a durable product, they consider not only the absolute number of times they think they will use the product, but also the number of time they will use the product relative to other consumers," write authors Rebecca W. Hamilton, Rebecca K. Ratner (both University of Maryland, College Park), and Debora Viana Thompson (Georgetown University). The ...
