Study Assesses Use of Fingerstick Blood Sample with i-STAT Point-of-Care Device

Loyola University Health System

Researchers have determined that fingerstick cardiac troponin I assay testing using thepoint-of-care i-STAT device is not accurate enough to determine the exact troponin level without the application of a corrective term.

Promising New Alloy for Resistive Switching Memory

American Institute of Physics (AIP)

Researchers have tested a number of oxide materials for their promise in resistive switching memories, and now a team of researchers in Singapore have demonstrated how conductive nano-filaments in amorphous titanium dioxide (TiO2) thin films could be utilized for resistive switching device applications.

Densest Array of Carbon Nanotubes Grown to Date

American Institute of Physics (AIP)

Carbon nanotubes’ outstanding mechanical, electrical and thermal properties make them an alluring material to electronics manufacturers. However, until recently scientists believed that growing the high density of tiny graphene cylinders needed for many microelectronics applications would be difficult. Now a team from Cambridge University in England has devised a simple technique to increase the density of nanotube forests grown on conductive supports about five times over previous methods.

Transmitting Future Asthma by Smoking Today

American Physiological Society (APS)

A new study confirms the lasting legacy of smoking. In the study, researchers exposed animal mothers to nicotine during pregnancy—a proxy for smoking—and found the grandchildren were also at an increased risk for asthma, despite the grandchildren never having been exposed to nicotine themselves.

Building the Best Brain: U-M Researchers Show How Brain Cell Connections Get Cemented Early in Life

Michigan Medicine - University of Michigan

When we’re born, our brains aren’t very organized, but as we grow and learn, things get a bit more stable. How and why does this happen -- and what happens when it doesn’t go normally? Researchers have made a major stride in understanding this process, called synapse maturation.

Study Explores Barriers to HIV Vaccine Response

Scripps Research Institute

Researchers at The Scripps Research Institute (TSRI) discovered that an antibody that binds and neutralizes HIV likely also targets the body’s own “self” proteins. This finding could complicate the development of HIV vaccines designed to elicit this protective antibody, called 4E10, and others like it, as doing so might be dangerous or inefficient.

Virginia Tech Researchers Reveal Why Traumatized Trees Don't 'Bleed' to Death

Virginia Tech

Researchers from Virginia Tech, the Georg-August University of Gottingen, Germany, and the Jackson Laboratory of Bar Harbor, Maine, have used a special type of microscope to discover how “check valves” in wood cells control sap flow and protect trees when they are injured.

Higher Calorie Diets Increase Weight Gain, Shorten Hospital Stays for Teens with Anorexia

University of California, San Francisco (UCSF)

Higher calorie diets produce twice the rate of weight gain compared to the lower calorie diets that currently are recommended for adolescents hospitalized with anorexia nervosa, according to a study by researchers at UCSF Benioff Children’s Hospital.
