A new method for making perovskite solar cells
Researchers have come up with a new way of making thin perovskite films for solar cells. The method forms perovskite crystals at room temperature, which could be helpful in mass production settings. The technique is especially well suited to make ultra-thin, semitransparent films, which could be used in photovoltaic windows.

East Antarctica melting could be explained by oceanic gateways
Researchers from the University of Texas at Austin have discovered two seafloor gateways that could allow warm ocean water to reach the base of Totten Glacier, East Antarctica's largest and most rapidly thinning glacier. The discovery probably explains the glacier's extreme thinning and raises concerns about how it will affect sea level rise. Their research was published in the March 16 edition of the journal Nature Geoscience.

Finding fault: New information may help understand earthquakes
New modeling and analyses of fault geometry in the Earth's crust by geoscientist Michele Cooke and colleagues at the University of Massachusetts Amherst are advancing knowledge about fault development in regions where one geologic plate slides past or over another, such as along California's San Andreas Fault and the Denali Fault in central Alaska.

Study: Past warming increased snowfall on Antarctica, affecting global sea level
A new study confirms that snowfall in Antarctica will increase significantly as the planet warms, offsetting future sea level rise from other sources -- but the effect will not be nearly as strong as many scientists previously anticipated because of other, physical processes.

Uncovering the secrets of super solar power perovskites
In a scant five years of development, hybrid perovskite solar cells have attained power conversion efficiencies that took decades to achieve with the top-performing conventional materials, but scientists have lacked a clear understanding of the precise goings on at the molecular level. New findings by University of Utah physicists help fill that void.

New research finds oceanic microbes behave in a synchrony across ocean basins
Researchers from the University of Hawai'i - Manoa and colleagues found that microbial communities in different regions of the Pacific Ocean displayed strikingly similar daily rhythms in their metabolism despite inhabiting extremely different habitats -- the nutrient-rich waters off California and the nutrient-poor waters north of Hawai'i. Furthermore, in each location, the dominant photoautotrophs appear to initiate a cascade effect wherein the other major groups of microbes perform their metabolic activities in a coordinated and predictable way.

Penn and ExxonMobil address long-standing mysteries behind anti-wear motor oil additive
Motor oil contains chemical additives that extend how long engines can run without failure, but, despite decades of ubiquity, how such additives actually work to prevent this damage have remained a mystery. Now, engineers from the University of Pennsylvania and ExxonMobil have teamed up to answer this question.

Social status has impact on overall health of mammals
High social status has its privileges -- when it comes to aging -- even in wild animals. In a first-of-its-kind study involving a wild species, Michigan State University researchers have shown that social and ecological factors affect animal health. The results, published in the current issue of Biology Letters, focused on spotted hyenas in Kenya.

Understanding plants' immune systems could lead to better tomatoes, roses, rice
Spring is just around the corner and for millions of Americans, that means planting a garden with plenty of fruits and vegetables, including tomatoes. Now, a University of Missouri research team has uncovered new regulations of defense pathways for plants. This discovery could lead to helping those home-grown tomatoes fight off certain bacteria better and has implications for pear trees, roses, soybeans and rice.

Urging HPV vaccine for boys could protect more people at same price
Whether vaccinating US boys against HPV in addition to girls is worth the cost has been hotly debated. But with HPV-related cancers in men on the rise, and coverage in girls stagnating below the levels needed to ensure that most people are protected, research suggests that devoting a portion of HPV funding to boys -- rather than merely attempting to improve female coverage -- may protect more people for the same price.
