After indulging in an assortment of goodies from Thanksgiving through the end of December, millions of Americans set New Year’s resolutions built on promises of slimming down and shaping up.
For many, the prospect of sweating at the gym five days a week or eliminating pizza as a food group loses its appeal after a week or two. When it comes to heart health, however, a radical lifestyle change isn’t required to affect positive change.
John Quindry, director of Auburn University’s Cardioprotection Research Laboratory, said far too many people associate hour-long elliptical machine sessions as the most effective means of building a healthy heart.
“There’s something about a new year where people muster up the courage to actually make some great claims and expectations for the year ahead, claims that most of the time go completely unfulfilled,’’ said Quindry, an assistant professor of exercise science in the College of Education’s Department of Kinesiology. “Just getting out and walking or jogging for the recommended 30 to 45 minutes most days is going to be enough to help.’’
Quindry said the point can’t be emphasized enough with February marking Heart Health Month. The American College of Sports Medicine and the Centers for Disease Control and Prevention both suggest 30 minutes of brisk walking as a benchmark for daily physical activity.
“They have what are called reduced exercise guidelines, which indicate even a little bit of physical activity can go a long way for health,’’ Quindry said. “It is overlooked by society. Despite established fitness and exercise standards, common expectations for a fitness program are all too often gauged by people like Lance Armstrong, people who have reached the pinnacle of athletic success.’’
Since the average person isn’t going to climb on a bicycle and compete in the Tour de France, however, Quindry said it’s important to tailor exercise regimens toward improving overall cardiovascular health. Through his animal-based laboratory research, Quindry and his collaborators have found that even a few days of exercise can provide a form of protection in the event of a heart attack.
In his lab experiments, Quindry has taken sedentary rats and exercised them through treadmill activity for three-day periods. After that period of moderate to vigorous exercise, the lab rats were subjected to experimentally-induced heart attacks, replicating a clinical heart attack in humans. Quindry has repeatedly found that the brief exercise regimen diminishes the severity of the heart attacks.
“The animal-based research has been structured so that it’s very clinically relevant,’’ Quindry said. “The animals we use exercise in proportion to the same intensities you and I would exercise for good health and fitness.
“Just three days of exercise overwhelmingly protects against heart attack damage,’’ Quindry said. “What we’re finding is that even a little bit of physical activity is more powerful than we once thought.’’

Thin-film solar cells made of crystalline silicon are inexpensive and achieve efficiencies of a good 14 percent. However, they could do even better if their shiny surfaces reflected less light. A team led by Prof. Christiane Becker from the Helmholtz-Zentrum Berlin (HZB) has now patented a sophisticated new solution to this problem.
"It is not enough simply to bring more light into the cell," says Christiane Becker. Such surface structures can even ultimately reduce the efficiency by...
A study in the journal Bulletin of Marine Science describes a new, blood-red species of octocoral found in Panama. The species in the genus Thesea was discovered in the threatened low-light reef environment on Hannibal Bank, 60 kilometers off mainland Pacific Panama, by researchers at the Smithsonian Tropical Research Institute in Panama (STRI) and the Centro de Investigación en Ciencias del Mar y Limnología (CIMAR) at the University of Costa Rica.
Scientists established the new species, Thesea dalioi, by comparing its physical traits, such as branch thickness and the bright red colony color, with the...

Graphene is considered a promising candidate for the nanoelectronics of the future. In theory, it should allow clock rates up to a thousand times faster than today’s silicon-based electronics. Scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) and the University of Duisburg-Essen (UDE), in cooperation with the Max Planck Institute for Polymer Research (MPI-P), have now shown for the first time that graphene can actually convert electronic signals with frequencies in the gigahertz range – which correspond to today’s clock rates – extremely efficiently into signals with several times higher frequency. The researchers present their results in the scientific journal “Nature”.
Graphene – an ultrathin material consisting of a single layer of interlinked carbon atoms – is considered a promising candidate for the nanoelectronics of the...
