Pinpointing the effects of fertilizer
Plant biologists at the University of Illinois and Michigan State University have pinpointed the area of genomes within nitrogen-fixing bacteria in roots, called rhizobia, that's being altered when the plant they serve is exposed to nitrogen fertilizer.

Changing monsoon patterns, more rain contribute to lower tea yield in Chinese provinces
Longer monsoon seasons with increased daily rainfall, aspects of climate change, are contributing to reduced tea yield in regions of China, with implications for crop management and harvesting strategies, according to findings by a global interdisciplinary team led by Tufts University researchers and published online today in Climate.

Scientists to unlock the secrets of DNA sequence
The team -- made up of scientists from the University of Illinois Center for the Physics of Living Cells in the United States, Johns Hopkins University in the United States, and UNIST -- discovered that DNA molecules directly interact with one another based on sequence even in the absence of protein molecules.

Methods used to create textiles also could help manufacture human tissues
Tissue engineering is a process that uses novel biomaterials seeded with stem cells to grow and replace missing tissues. When certain types of materials are used, the 'scaffold' that are created to hold stem cells eventually degrade, leaving natural tissue in its place. Elizabeth Loboa, dean of the MU College of Engineering, and her team recently tested new methods to make the process of tissue engineering more cost effective and producible in larger quantities.

Dynamic model helps understand healthy lakes to heal sick ones
Development of a dynamic model for microbial populations in healthy lakes could help scientists understand what's wrong with sick lakes, prescribe cures and predict what may happen as environmental conditions change. Those are among the benefits expected from an ambitious project to model the interactions of some 18,000 species in a well-studied Wisconsin lake.

Can corals keep up with ocean acidification?
An interdisciplinary team of researchers led by University of Delaware professors Wei-Jun Cai and Mark Warner has successfully measured both pH and carbonate ion concentration directly inside the calcifying fluid found in coral, an important development in the study of how ocean acidification will affect marine calcifying organisms such as corals and shellfish.

Protein SIRT5 linked to healthy heart function
Cornell researchers, working in collaboration with scientists in Switzerland, have identified a strong connection between a protein, SIRT5, and healthy heart function. SIRT5 has the ability to remove a harmful protein modification known as lysine succinylation, which robs the heart of its ability to burn fatty acids efficiently to generate the energy needed for pumping.

UC Berkeley, Stanford find LA LGBT Center's canvassing conversations reduce transphobia
Stanford University and UC Berkeley researchers report that volunteer canvassers -- both transgender and not -- reduced voters' prejudice against transgender people. Last year the researchers triggered fierce debate about the need for transparency in social science research when they raised doubts about a now-retracted study of the Los Angeles LGBT Center's door-to-door canvassing on gay marriage by other researchers that appeared in Science. They discovered irregularities in that study's data while conducting this follow-up study.

UOG scientists seek genetic reasons for coral reef survival
Coral reefs around the world are increasingly under threat from coral bleaching which destroys colonies and interrupts the food chain they support. Scientists at the University of Guam Marine Laboratory are using a new genetic sequencer to search for the biological mechanisms that allow some colonies to survive and thrive while others die.

Key advance: UC Davis neuroscientists get a new look into how we read
Neuroscientists at UC Davis have come up with a way to observe brain activity during natural reading. It's the first time researchers have been able to study the brain while reading actual texts, instead of individual words, and it's already helping settle some ideas about just how we read.

Network governance connects people to solve collective environmental problems
Ecological systems, and ecological problems, are not nicely contained within neat human boundaries. 'Network governance' can help big, agency- and border-spanning conservation alliances govern themselves, researchers argue in a special April issue of the Ecological Society of America's journal Frontiers in Ecology and the Environment. The Special Issue explores the life cycle of networks, plumbs examples in cities and wilderness, and examines community-based conservation within larger governance networks.

Duke study uncovers genetic elements that drive regeneration
Salamanders and fish possess genes that can enable healing of damaged tissue and even regrowth of missing limbs. The key to regeneration lies not only in the genes, but in the DNA sequences that regulate expression of those genes in response to an injury. Duke researchers have discovered regulatory sequences that they call 'tissue regeneration enhancer elements' or TREEs, which can turn on genes in injury sites.

University of Georgia Skidaway Institute of Oceanography scientist Dana Savidge is leading a team, which includes UGA Skidaway Institute scientist Catherine Edwards, to investigate the dynamic forces that characterize those waters.

Supermassive black holes may be lurking everywhere in the universe
One of the largest supermassive black holes on record has been discovered in an unexpected place: a relatively sparse region of the local universe where massive galaxies -- the typical home of these huge black holes -- are few and far between. According to UC Berkeley astronomer Chung-Pei Ma, there could be many more such black holes -- quiescent quasars -- hiding in the universe's deserts. This one may be or once was a binary black hole.
