Where’s the Center of North America? UB Geographer’s New Method Finds a New Answer

Where is the geographic center of a state, country or a continent? It’s a question fraught with uncertainty. Do you include water in your calculation? What happens when the shoreline shifts? But to University at Buffalo geographer Peter Rogerson, the challenge of finding a middle doesn’t mean you shouldn’t try.

UF/IFAS Researcher to Lead $1 Million Study to Increase Global Wheat Production

WheatWeather091216.jpg

Md Ali Babar, a UF/IFAS agronomy assistant professor and his team of researchers, hope to increase the harvest index from 45 to 60 percent, which translates to much more wheat. The harvest index quantifies a crop’s yield versus the amount of biomass – shoots and roots – that it produces.

Songbirds Divorce, Flee, Fail to Reproduce Due to Suburban Sprawl

New University of Washington research finds that for some songbirds, urban sprawl is kicking them out of their territory, forcing divorce and stunting their ability to find new mates and reproduce successfully, even after relocating.

University of Washington-Led Study Shows New Global Evidence of the Role of Humans, Urbanization in Rapid Evolution

It has long been suspected that humans and the urban areas we create are having an important — and surprisingly current and ongoing — effect on evolution, which may have significant implications for the sustainability of global ecosystems. A new multi-institution study led by the University of Washington that examines 1,600 global instances of phenotypic change — alterations to species' observable traits such as size, development or behavior — shows more clearly than ever that urbanization is affecting the genetic makeup of species that are crucial to ecosystem health and success.

Worries About Food Waste Appear to Vanish When Diners Know Scraps Go to Compost

Diners waste far less food when they’re schooled on the harm their leftovers can inflict on the environment. But if they know the food is going to be composted instead of dumped in a landfill, the educational benefit disappears.

Fossil Fuel Formation: Key to Atmosphere’s Oxygen?

blackshalecroplg_LK.jpg

For the development of animals, nothing — with the exception of DNA — may be more important than oxygen in the atmosphere. A study now online in the February issue of Earth and Planetary Science Letters links the rise in oxygen to a rapid increase in the burial of sediment containing large amounts of carbon-rich organic matter.

Biologist's Ant Research Provides Long-Term Look at Effects of Climate Change

Shannon_Pelini_BEEG6197.jpg

Many scientists have attempted to tackle how climate change will affect the natural world by determining the thermal tolerance of various species, then predicting what will happen to them as our world warms. However, this approach as a way to understand nature has its drawbacks because one species never acts alone, so comprehending how global change impacts these interactions is crucial to a holistic understanding.

Breast cancer researchers from the Florida campus of The Scripps Research Institute (TSRI) have developed a novel approach for identifying how chemicals in the environment—called environmental estrogens—can produce infertility, abnormal reproductive development, including “precocious puberty,” and promote breast cancer.
