Tweed Valley a 'natural laboratory' to test carbon sequestration theory
Tweed Valley a ’natural laboratory’ to test carbon sequestration theory
An idea to enhance natural carbon capture from olivine weathering has never been tested at scale. University of Sydney geoscientists have proposed the Tweed Valley as a laboratory and gained some interesting initial results. Geoscientists at the University of Sydney have discovered a natural laboratory to test claims that the carbon captured during the erosion and weathering of common rocks could be a viable mitigation strategy against global warming.

Using electric current to stabilize low-permeability soils
Using electric current to stabilize low-permeability soils
Scientists have developed a new approach to stabilizing clay soils. The method involves using a battery-like system to apply electric current to carbonate and calcium ions in order to promote soil consolidation. Their findings were published yesterday in Scientific Reports. According to figures released by the UN yesterday, natural disasters have killed more than 1.2 million people since 2000 and cost nearly $ 3 trillion.These pressing threats bring into sharp focus the need for new answers to the problem of soil stabilization.

Carnivores living near people feast on human food, threatening ecosystems
Researchers collected bone and fur samples from almost 700 carnivores across four Great Lakes states (top) to compare their diets to the extent of human development, which varied from minimal to urban sprawl (bottom). Phil Manlick.

Researching ecosystems from the air
Researching ecosystems from the air
It looks absolutely idyllic, watching the Heck cattle and Konik horses grazing in the meadows in the Emsaue wet meadows near the village of Vadrup. This pasture landscape, covering an area of 33 hectares and used all year round, lies in the Emsaue nature conservation area and was set up in 2004 as part of the implementation of the plan to protect the wet meadows by the River Ems.

Clean Air Act reduced racial disparities in pollution
Air pollution has disproportionately hurt minority and low-income communities, leading to reduced life expectancy, research has found. Yet a lack of data has stymied efforts to quantify the problem-and its causes-nationwide. A recent study, anchored by new satellite-based measures of air quality, found some encouraging news: The gap between Black and white Americans' particulate exposure has declined over the past two decades, due largely to enforcement of the Clean Air Act in the country's most polluted areas.

Vaporised metal in the air of an exoplanet
An international team of researchers led by the National Centre of Competence in Research PlanetS of the University of Bern and the University of Geneva studied the atmosphere of the ultra-hot exoplanet WASP-121b. In it, they found a number of gaseous metals. The results are a next step in the search for potentially habitable worlds.

Airdropping sensors from moths: Researchers use flying insects to drop sensors from air, land them safely on the ground
Airdropping sensors from moths: Researchers use flying insects to drop sensors from air, land them safely on the ground
UW researchers have created a sensor system that can ride on the back of a moth. Shown here is a Manduca sexta moth with the sensor on its back. Mark Stone/University of Washington There are many places in this world that are hard for researchers to study, mainly because it's too dangerous for people to get there.

Unveiling the Accuracy of Tsunami Predictions
Fishing boats pushed on to land in the city of Talcahunao, Chile by a tsunami, March 2010. Photo credit: Peter Burgess EU/ECHO New study validates accuracy in predicting the first wave, but weakness in forecasting ‘trailing' waves Residents of coastal towns in Chile remember the catastrophic earthquakes that struck their country in 1960 and 2010, not always for the quakes themselves but for the tsunamis that followed.

Thinning forests no defence against fires
Thinning forests no defence against fires
Having logging machines "thin" forest for fire reduction is largely ineffective, a new peer-reviewed, scientific study has found. The study, led by researchers at The Australian National University and published in the journal Conservation Letters , compared fire severity in unthinned versus thinned forest burned in the 2009 wildfires.

City dwellers just as willing to help a stranger
People in cities are just as likely to help a stranger on the street as those in towns and villages, finds a study by UCL researchers. Helping behaviour was higher in more affluent areas, as social deprivation predicted lower levels of helping, according to the results of the UK-based study published in Proceedings of the Royal Society B .

Are there hydroelectric power plants that are fish-friendly?
Complex investigation of new hydropower plants Modern hydroelectric power plants do not always protect fish better than conventional ones. In addition to the technologies employed, the specific location of the plant and the fish species being present at that location also play a role in fish protection.

Groundwater depletion in US High Plains leads to bleak outlook for grain production
The depletion of groundwater sources in parts of the United States High Plains is so severe that peak grain production in some states has already been passed, according to new research. An international team of scientists, including experts from the University of Birmingham, has extended and improved methods used to calculate peak oil production to assess grain production in three US states, Nebraska, Texas and Kansas.

With multilayered approach, a filter to meet freshwater supply needs
In search of a better way to desalinate water, a Yale-led team of researchers has turned to swimsuit material for inspiration.  Reverse osmosis, which uses membranes to remove unwanted salts, has been the gold standard for desalination and wastewater reuse. The challenge that scientists have run into, however, is that the material that best filters out impurities  3/4  polyamide  3/4  is highly susceptible to chlorine.

40,000 years of adapting to sea-level change on Alor Island
40,000 years of adapting to sea-level change on Alor Island
Early people were rapidly adapting to climate change as they made their way towards Australia tens of thousands of years ago, new research shows. Shells, fish bones and fishhooks found on the Indonesian island of Alor show how people lived and adapted to the environment more than 40,000 years ago. Researchers from The Australian National University (ANU) led the team which excavated a cave - called Makpan - on Alor's south-west coast.

Researchers Use Satellite Imaging to Map Groundwater Use in California’s Central Valley
Satellite data reveal variability in intensity of groundwater use for different crops, a boon for irrigation policymaking across the state Researchers at the University of California San Diego report in a new study a way to improve groundwater monitoring by using a remote sensing technology (known as InSAR), in conjunction with climate and land cover data, to bridge gaps in the understanding of sustainable groundwater in California's San Joaquin Valley.

Mud-slurping chinless ancestors had all the moves
Life restoration of Cephalaspis, a typical osteostracan, swimming over the substrate. Hugo Salais (Metazoa Studio) A team of researchers, led by the University of Bristol, has revealed our most ancient ancestors were ecologically diverse, despite lacking jaws and paired fins. Long before they evolved out of the water, our ancient ancestors were simple fish-like creatures, but without fins or chins, who survived by filtering nutrients from the sediment.

Analysis: Rising sea levels could leave millions at risk by 2100
Ilan Kelman (UCL Institute for Risk & Disaster Reduction) joins experts in examining 33 studies of how rising sea levels will affect migration patterns, 'trapped populations' and call for policymakers to institute measures to protect residents living in high-risk areas. An article in 2011 shocked many by suggesting that up to 187 million people could be forced to leave their homes as a result of two metres of sea level rise by 2100.
