Consistency is the key to success in bread baking and biology
Whether you're baking bread or building an organism, the key to success is consistently adding ingredients in the correct order and in the right amounts, according to a new genetic study by University of Michigan researchers.

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.

Discovery demystifies origin of life phenomenon
Biomolecules, if large enough (several nanometers) and with an electrical charge, will seek their own type with which to form large assemblies. This 'self-recognition' of left-handed and right-handed molecule pairs is featured in the March 10, 2015, issue of Nature Communications.

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.

Iron-oxidizing bacteria found along Mid-Atlantic Ridge
Bacteria that live on iron were found for the first time at three well-known vent sites along the Mid-Atlantic Ridge. These bacteria likely play an important role in deep-ocean iron cycling, and are dominant members of communities near and adjacent to sulfur-rich hydrothermal vents prevalent along the Mid-Atlantic Ridge. This group of iron-oxidizing bacteria, Zetaproteobacteria, appears to be restricted to environments where iron is plentiful, suggesting they are highly evolved to utilize iron for energy.

Predicting the extent of flash flooding
Devastating floodwaters such as those experienced during Iowa's Flood of 2008 are notoriously difficult to predict. So a team of University of Iowa mathematicians and hydrologists collaborating with the Iowa Flood Center set out to gain a better understanding of flood genesis and the factors impacting it. They were able to do this by zeroing in on the impacts of certain rainfall patterns at the smallest unit of a river basin: the hillslope scale.

Bioelectricity plays key role in brain development and repair
Embryonic cells communicate, even across long distances, using bioelectrical signals, and they use this information to know where to form a brain and how big that brain should be. These signals are more than an on/off switch; rather they function like software that enables a computer to carry out complex activities. Manipulating these signals can repair genetic defects and induce development of healthy brain tissue where it would not ordinarily grow.

Penn researchers show how rivers creep and flow to shape landscapes over time
Most models predict that rivers only transport sediment during conditions of high flow and, moreover, that only particles on the surface of the river bed move due to the force of the flowing water above. But using a custom laboratory apparatus, a new study by University of Pennsylvania researchers shows that, even when a river is calm, sediment on and beneath the river bed slowly creeps forward.

Innovative light therapy reaches deep tumors
Using a mouse model of cancer, researchers at Washington University School of Medicine in St. Louis have devised a way to apply light-based therapy to deep tissues never before accessible. Instead of shining an outside light, they delivered light directly to tumor cells, along with a photosensitive source of free radicals that can be activated by the light to destroy cancer. And they accomplished this using materials already approved for use in cancer patients.
