Research shows tears shed light on presence of eye disease

Your optometrist may make you cry during your next appointment, but don’t worry — it’s for your own good. Amy Herr, UC Berkeley assistant professor in the Department of Bioengineering, and graduate student Kelly Karns have developed a new method of diagnosing the eye disease Sjogren’s syndrome by analyzing tears.

Study suggests evaporation from trees cools global climate

In addition to providing shade and oxygen, a Lawrence Berkeley National Laboratory researcher’s study published Sept. 14 in the journal Environmental Research Letters proposes that trees could help cool the planet through evaporation. According to the study, evaporated water from trees adds to low-level clouds, which reflect solar radiation back to

Study could help improve the efficiency of solar cells

UC Berkeley researchers laid the groundwork for potentially developing more energy-efficient solar cells in a new study published Sept. 15 in the journal Physical Review Letters. In the past, researchers have focused on looking at domains — the crystal surface of a solar cell that can convert sunlight into energy

Study uncovers mechanism behind hearing condition

A study by a team of UC Berkeley neuroscientists has uncovered new cerebral mechanisms behind tinnitus, a currently incurable condition that produces a constant ringing or buzzing sound in the ear in the absence of other noise. The study, published Sept. 6 in the journal Proceedings of the National Academy

Researchers develop energy-efficient window coating

UC Berkeley and Lawrence Berkeley National Laboratory researchers developed a coating material for windows that can control the amount of heat from the sun that enters a room, setting the groundwork to save energy in large commercial buildings and homes. The material — made of semiconductor nanocrystals — has the

Campus study finds origin of spread of tree pathogen

Researchers at UC Berkeley have found that the spread of a cypress tree-killing pathogen to six continents very likely originated in trees exported from California to Europe in the 1920s. The study, published Thursday in the journal Phytopathology, determined that the cypress canker disease — Seiridium cardinale — has infected
