With more than two dozen companies in Pennsylvania manufacturing potato chips, it is no wonder that researchers in Penn State's College of Agricultural Sciences have developed a novel approach to more efficiently convert potato waste into ethanol. This process may lead to reduced production costs for biofuel in the future and add extra value for chip makers.
NASA’s Aqua satellite and NOAA's GOES-East satellite provided an infrared and visible look at Atlantic Hurricane Gert. Both images showed the storm was being affected by wind shear and had become elongated.
The ancient Romans were famous for their advanced water supply. But the drinking water in the pipelines was probably poisoned on a scale that may have led to daily problems with vomiting, diarrhoea, and liver and kidney damage. This is the finding of analyses of water pipe from Pompeii.
- The concentrations were high and were definitely problematic for the ancient Romans. Their drinking water must have been decidedly hazardous to health.
CFCs, greenhouse gases, and naturally occurring emissions of halogens will shape how volcanoes impact the ozone layer into the next century
Gastric carcinoma is one of the most common causes of cancer-related deaths, primarily because most patients present at an advanced stage of the disease. The main cause of this cancer is the bacterium Helicobacter pylori, which chronically infects around half of all humans. However, unlike tumour viruses, bacteria do not deposit transforming genes in their host cells and how they are able to cause cancer has so far remained a mystery. An interdisciplinary research team at the Max Planck Institute in Berlin in collaboration with researchers in Stanford, California, has now discovered that the bacterium sends stem cell renewal in the stomach into overdrive – and stem cell turnover has been suspected by many scientists to play a role in the development of cancer. By showing that the stomach contains two different stem cell types, which respond differently to the same driver signal, they have uncovered a new mechanism of tissue plasticity. It allows tuning tissue renewal in response to bacterial infection.
In a new study, researchers at The Ohio State University estimate algal blooms at two Ohio lakes cost Ohio homeowners $152 million in lost property value over six years.
Meanwhile, a related study suggests that algae is driving anglers away from Lake Erie, causing fishing license sales to drop at least 10 percent every time a bloom reaches a moderate level of health risk. Based on those numbers, a computer model projects that a severe, summer-long bloom would cause up to $5.6 million in lost fishing revenue and associated expenditures by anglers.
