Monitor climate change, not predators, to protect lake diversity: Study

Fri, 23 Mar 18 00:01:50 -0700

Climate change and other environmental factors are more threatening to fish diversity than predators, according to new research from the University of Guelph. It is a surprising and important finding, as humans rely upon freshwater lakes for more than one-fifth of their protein needs worldwide, says lead author Prof. Andrew MacDougall in U of G's Department of Integrative Biology.

Because of agriculture, the Gulf of Mexico will suffocate for decades longer

Thu, 22 Mar 18 00:10:10 -0700

Nitrogen runoff has created a massive oxygen-deprived 'dead zone' in the Gulf of Mexico, but even if the runoff was completely eliminated, it would still take at least 30 years for the area to recover, a new study estimates.

Flood protection is everyone's responsibility

Wed, 21 Mar 18 00:10:50 -0700

Scientists in Vienna have studied the complex interplay between flooding events and economic decisions. Private businesses should not shoulder the responsibility for flood protection alone. In prosperous countries in particular, it makes sense for central government to establish the necessary infrastructure for flood protection.

Study of climate change could lead to understanding future of infectious disease

Tue, 20 Mar 18 00:11:40 -0700

Over the past 34 years, rainfall in Uganda has decreased by about 12 percent even though many of the global climate models predict an increase in rainfall for the area, according to an international team of researchers. Rainfall levels in Uganda impact agriculture, food security, wildlife habitats and regional economics as well as the prevalence of certain diseases.

Studying DNA of ancient humans from Morocco reveals ancestral surprises

Thu, 15 Mar 18 00:12:20 -0700

After sequencing DNA in bone matter of several 15,000-year-old humans from North Africa, a region critical for understanding human history but one in which it has been challenging to connect genetic dots, researchers report a notable lack of relatedness to ancient Europeans, in their specimens - a finding that rules out hypotheses of gene flow from southern Europe into northern Africa at a particular time.

Cell-sized mold makes gelatin gels (jelly) 10 times stiffer

Thu, 15 Mar 18 00:14:20 -0700

Micro-sized gels are indispensable for biomedical, cosmetic, and food materials, warranting importance of controlling mechanical properties of a single microgel for application usages. Here it was shown that space sizes for gelation change mechanical properties of gelatin gels. Detailed analysis in the microgel structure revealed that changes in secondary structures of gelatin protein induced the increase of elasticity. These findings shed light on the ability of space-size as a controller of mechanical properties of gels.

Elevated lead in private wells could pose health risks
Since the Flint Water Crisis in Michigan, concern in the US over lead in drinking water has increased. Information about water from private wells has been limited because such wells are exempt from the 1974 Safe Drinking Water Act, the 1986 Lead Ban and the 2011 Reduction of Lead in Drinking Water Act. Now, researchers report a case study in ACS' journal Environmental Science
