New polymer films conduct heat instead of trapping it
Engineers have flipped the picture of the standard polymer insulator, by fabricating thin polymer films that conduct heat -- an ability normally associated with metals. In experiments, they found the films, which are thinner than plastic wrap, conduct heat better than many metals, including steel and ceramic.

Morning exercise can improve decision-making across the day in older adults
A study of older Australians has found a morning bout of moderate-intensity exercise improves cognitive performance like decision-making across the day compared to prolonged sitting without exercise. It also shows that a morning bout of exercise combined with brief walking breaks to frequently disrupt sitting throughout an eight-hour day can boost short-term memory compared to uninterrupted sitting, according to the study.

Plant cells eat their own ... membranes and oil droplets
Biochemists have discovered two ways that autophagy, or self-eating, controls the levels of oils in plant cells. The study describes how this cannibalistic-sounding process actually helps plants survive, and suggests a way to get bioenergy crops to accumulate more oil.

US 1 of 8 nations where child and adolescent health improved but maternal mortality worsened
The United States is one of only eight countries in the world where decreases in child and adolescent mortality over a 27-year period haven't also been matched by reductions in maternal mortality, according to a new scientific study. This divergent trend also was found in American Samoa, Canada, Greece, Guam, Jamaica, St. Vincent and the Grenadines, and Zimbabwe. Of these countries, the United States had the largest increase in maternal mortality rate at 67.5%.

Inhaled hydrogen could protect the brain during heart-lung bypass

Inhaled hydrogen could protect the brain during heart-lung bypass
Newborns with life-threatening congenital heart disease often need open-heart surgery with cardiopulmonary bypass, which carries a risk of damaging the brain. Critically ill newborns who are placed on ECMO are at even higher risk for brain injury. A new study, performed in a large animal model, suggests that adding a dash of hydrogen to the usual mix of respiratory gases could further protect babies' brains. The researchers are now planning a small safety trial.

Susceptibility to disease develops during childhood
Traumatized children and children who develop multiple allergies tend to suffer in adulthood from chronic inflammatory diseases and psychiatric disorders. Researchers have demonstrated this in a study in which they identified five classes of early immune-system programming.

New charge transfer and separation process
Scientists have discovered a new charge transfer and separation process named Twisted Intramolecular Charge Shuttle (TICS), paving a new avenue for chemists to construct unique and useful fluorescent probes in a wide range of chemical families of fluorophores.

How the olfactory brain affects memory

How the olfactory brain affects memory
How sensory perception in the brain affects learning and memory processes is far from fully understood. Neuroscientists have discovered a new aspect of how the processing of odors impacts memory centers. They showed that the piriform cortex -- a part of the olfactory brain -- has a direct influence on information storage in our most important memory structure, the hippocampus.

Consumption of caffeinated energy drinks rises in the United States
According to a new study, energy drink consumption in the United States has increased substantially over the past decade among adolescents, young adults, and middle-aged adults. Energy drink consumers had significantly higher total caffeine intake compared with non-consumers and the beverages represented a majority of their total daily caffeine. Use by young adults continues to steadily rise.

Fecal transplants may be best answer to antibiotic-resistant bacteria

Fecal transplants may be best answer to antibiotic-resistant bacteria
Unlike antibiotics, which are destructive by definition, fecal transplants or microbial replacement therapies, repopulate the gut with a diverse group of microbes that may block the C. diff's spore from germinating and propagating disease via its toxins. Transplants have several delivery methods, including enemas, capsules and direct instillation, to replace the diverse flora that maintain health and improve metabolism.

Caffeine prevents PGE1-induced disturbances in respiratory neural control

Caffeine prevents PGE1-induced disturbances in respiratory neural control
Researchers propose PGE exerts adenosine-mediated effects on brainstem mechanisms of respiratory control, which may lead to destabilization of breathing in human infants undergoing treatment for congenital heart disease. Prostaglandin's effects could be mediated thorough microglia, and caffeine could be a convenient treatment to prevent respiratory instability in infants receiving PGE1 infusion.

Astronomers discover 2,000-year-old remnant of a nova
Researchers have discovered the remains of a nova in a galactic globular cluster, located near the center of Messier 22. The finding, using modern instruments, confirms one of the oldest observations of an event outside the solar system.
