Contemporary pollutants can reach deep wells that tap fossil aquifers, says a study by an international team of researchers.

Red blood cell variation linked to natural malaria resistance
May 19, 2017 10:23 AM - University of Oxford

A study from the Wellcome Trust Sanger Institute, the Wellcome Trust Centre for Human Genetics and their collaborators have identified a genetic rearrangement of red blood cell glycophorin receptors that confers a 40 per cent reduced risk from severe malaria.

Mosquitoes that spread Zika virus could simultaneously transmit other viruses
May 19, 2017 10:08 AM - Colorado State University

A new study led by Colorado State University researchers found that Aedes aegypti, the primary mosquito that carries Zika virus, might also transmit chikungunya and dengue viruses with one bite. The findings shed new light on what’s known as a coinfection, which scientists said is not yet fully understood and may be fairly common in areas experiencing outbreaks.

Using Seaweed to Kill Invasive Ants

Scientists at the University of California, Riverside have developed an inexpensive, biodegradable, seaweed-based ant bait that can help homeowners and farmers control invasive Argentine ant populations.

In Next Decades, Frequency of Coastal Flooding Will Double Globally
May 19, 2017 08:21 AM - USGS

The frequency and severity of coastal flooding throughout the world will increase rapidly and eventually double in frequency over the coming decades even with only moderate amounts of sea level rise, according to a new study released today in “Nature Scientific Reports.”

This increase in flooding will be greatest and most damaging in tropical regions, impairing the economies of coastal cities and the habitability of low-lying Pacific island nations. Many of the world's largest populated low-lying deltas (such as the Ganges, Indus, Yangtze, Mekong and Irrawaddy Rivers), also fall in or near this affected tropical region.

Significant groundwater loss in California's Central Valley during recent droughts

A new study from researchers at UCLA and the University of Houston reveals estimates of significant groundwater loss in California’s Central Valley during the recent drought and sparks questions of sustainability for the important agricultural area.

Photocatalyst makes hydrogen production 10 times more efficient

Hydrogen is an alternative source of energy that can be produced from renewable sources of sunlight and water. A group of Japanese researchers has developed a photocatalyst that increases hydrogen production tenfold.

Climate stabilization: Planting trees cannot replace cutting CO2 emissions
May 18, 2017 01:36 PM - Potsdam Institute for Climate Impact Research (PIK)

Growing plants and then storing the CO2 they have taken up from the atmosphere is no viable option to counteract unmitigated emissions from fossil fuel burning, a new study shows. The plantations would need to be so large, they would eliminate most natural ecosystems or reduce food production if implemented as a late-regret option in the case of substantial failure to reduce emissions. However, growing biomass soon in well-selected places with increased irrigation or fertilization could support climate policies of rapid and strong emission cuts to achieve climate stabilization below 2 degrees Celsius.

Flat Antarctica — Land height could help explain why Antarctica is warming slower than the Arctic
May 18, 2017 01:27 PM - European Geosciences Union

Temperatures in the Arctic are increasing twice as fast as in the rest of the globe, while the Antarctic is warming at a much slower rate. A new study published in Earth System Dynamics, a journal of the European Geosciences Union, shows that land height could be a “game changer” when it comes to explaining why temperatures are rising at such different rates in the two regions.

Water Efficiency in Rural Areas is Getting Worse, Even as it Improves in Urban Centers
May 18, 2017 01:06 PM - North Carolina State University

A nationwide analysis of water use over the past 30 years finds that there is a disconnect between rural and urban areas, with most urban areas becoming more water efficient and most rural areas becoming less and less efficient over time.
