A largely overlooked but significant factor in marine ecology concerns the effects of variable pH on the growth rate and abundance of coastal marine phytoplankton, the base of the marine food chain in productive coastal waters. The pH of the open ocean varies very little. This has led to the common, but faulty, assumption that the pH of coastal waters also varies little and is unimportant.
In an article in a recent issue of the scientific journal Marine Ecology Progress Series, URI Graduate
The experiences of millions of people have proved that antidepressants work, but only with the advent of sophisticated imaging technology have scientists begun to learn exactly how the medications affect brain structures and circuits to bring relief from depression.
Researchers at the University of Wisconsin-Madison and UW Medical School recently added important new information to the growing body of knowledge. For the first time, they used functional magnetic resonance imaging (fMRI)–tech
The unique capabilities of a NASA earth-observing satellite have allowed researchers to view the effects of a major earthquake that occurred in 2001 in Northern India near the border of Pakistan.
Lead author Bernard Pinty of the Institute for Environment and Sustainability in the Joint Research Centre of the European Commission, Ispra, Italy, and colleagues from the U.S., France and Germany, used the Multi-angle Imaging SpectroRadiometer (MISR) instrument on NASAs Terra satellite to o
US fertility experts today (Thursday 6 February) published the first conclusive evidence that lead is linked to male infertility.
A report in Europe’s leading reproductive medicine journal Human Reproduction[1] concludes that exposure to lead damages sperm function and may be a contributory cause of unexplained male infertility.[2]
The findings have led principal investigator Dr Susan Benoff to urge doctors to measure lead in seminal plasma when evaluating men from couples with unex
When developing a treatment plan for cervical cancer, it is important to be able to determine a patients prognosis, ideally at the time of diagnosis. Existing methods to arrive at a prognosis can be time consuming, inaccurate and may require specialized software. Therefore, doctors from the Washington University School of Medicine developed – and validated – an accurate, reproducible and quick prognostic system.
The researchers created a grading scale to use in conjunction with a simp
In laboratory tests, Penn State environmental engineers have shown that wastewater from a Pennsylvania confectioner, apple processor, and potato chip maker can produce hydrogen gas worth $80,000 a year or more. Steven Van Ginkel, doctoral candidate, and Dr. Sang-Eun Oh, postdoctoral researcher in environmental engineering, conducted the tests.
“In addition to hydrogen, which can be used as a fuel and industrial feedstock, methane, the main component of natural gas, can be generated from the
