Conservation works: Forests for water in eastern Amazonia
A new study published in the Journal of Hydrology led by WHRC scientist Prajjwal Panday found that large protected areas in the Xingu River Basin have helped shield this Amazonian watershed from the effects observed in its less-protected neighbor, the Araguaia-Tocantins.

Levee detonations reduced 2011 flood risk on Mississippi River, UCI-led study finds
A controversial decision in 2011 to blow up Mississippi River levees reduced the risk of flooding in a city upstream, lowering the height of the rain-swollen river just before it reached its peak, according to a newly published computer modeling analysis led by UC Irvine scientists.

Squid enrich their DNA 'blueprint' through prolific RNA editing
RNA editing of genomic information was thought to be sparingly used, based on a limited number of studies in mammals and flies. But recently, MBL Whitman Investigator Joshua Rosenthal and colleagues discovered the most prolific usage yet of RNA editing in the common squid, Doryteuthis pealeii, a behaviorally sophisticated marine organism that has long been prized for studies of the nervous system.

HAWC Observatory to study universe's most energetic phenomena
The High Altitude Water Cherenkov (HAWC) Gamma-Ray Observatory is the newest tool available to visualize the universe's most explosive events and learn more about the nature of high-energy radiation. Construction is now complete on HAWC's 300th and final detector tank, and the observatory will soon begin collecting data at full capacity. This milestone will be marked with an inaugural event at the observatory on March 19-20, 2015.

Even at a molecular level, taking it slow helps us cope with stress
UC Berkeley scientists have identified a new molecular pathway critical to aging. They found that by slowing down the activity of mitochondria in the blood stem cells of mice, they could enhance the cells' capacity to handle stress and rejuvenate old blood.

World Heritage Sites risk collapse without stronger local management
Without better local management, the world's most iconic ecosystems are at risk of collapse under climate change, say researchers in Science. Protecting places of global environmental importance such as the Great Barrier Reef and the Amazon rainforest from climate change will require reducing the other pressures they face, for example overfishing, fertilizer pollution or land clearing.

An improved method for coating gold nanorods
Researchers have fine-tuned a technique for coating gold nanorods with silica shells, allowing engineers to create large quantities of the nanorods and giving them more control over the thickness of the shell. Gold nanorods are being investigated for use in a wide variety of biomedical applications, and this advance paves the way for more stable gold nanorods and for chemically functionalizing the surface of the shells.

How planthoppers got their wings
Each year, rice faces a big threat from a sesame seed-sized insect called the brown planthopper. Now, a study in the journal Nature reveals the molecular switch that enables some planthoppers to develop short wings and others long based on environmental conditions such as day length and temperature -- a major factor in their ability to invade new rice fields.

Beetles beat out extinction
A new study combs through fossil records to arrive at a unique new perspective: The rich diversity of beetles results more from low extinction rates rather than high origination rates. Through these fossils, researchers could plot the population fluxes of beetles as far back as their origins in the Premian period 284 million years ago.

Protein sequencing solves Darwinian mystery of 'strange' South American mammals
Scientists have resolved pieces of a nearly 200-year-old evolutionary puzzle surrounding the group of mammals that Charles Darwin called the 'strangest animals ever discovered.' New research shows that South America's 'native ungulates' are related to mammals like horses rather than elephants and other species with ancient evolutionary ties to Africa. The findings are based on protein sequences, which allow researchers to peek back in time up to 10 times farther than they can with DNA.

Plants' defensive responses have downstream effects on nearby ecosystems
Chemical changes that occur in tree leaves after being attacked by insects and mammals can impact nearby streams, which rely on fallen plant material as a food source, report scientists from the University of Chicago Department of Ecology and Evolution. The study, published March 17 in the journal Proceedings of the Royal Society B, shows how interactions between terrestrial and aquatic ecosystems are an essential part of understanding ecological responses to climate change.
