Exposure to air pollution while in the womb is linked to adverse changes in cell processes in new-born babies      (via sciencedaily.com)     Original source 

Exposure to air pollution while in the womb is linked to alterations in proteins that can be detected after a baby is born, and which affect cell processes such as autophagy, the 'self-eating' of damaged cells that occurs in response to stress.

Surfactants can cause toxic chemicals in aerosols to last longer in the air      (via sciencedaily.com)     Original source 

Research has found that hazardous chemicals commonly encountered in aerosols, such as those produced by cooking and cleaning, can be 'protected' in 3D structures formed by surfactants, causing them to last longer in the air.

Atmospheric scientists reveal much of Houston's ozone exceedance due to air flows from the north      (via sciencedaily.com)     Original source 

Atmospheric science researchers published findings on Houston's ozone. They found that while local emissions play a role in the rise of Houston's ozone levels, most of the pollutants are carried in from other parts of the country.

Urban parks built on former waste incineration sites could be lead hotspots      (via sciencedaily.com) 

A new study finds that surface soil in parks and playgrounds built on former waste incineration and ash disposal sites may contain levels of lead exceeding EPA safety standards for areas where children play. The contamination, which can persist long after an incinerator is closed, stems from burning paint, pipes and other products that contained lead. Sites in hundreds of U.S. and Canadian cities could be contaminated. Increased monitoring is needed to pinpoint hotspots.

High levels of particulate air pollution associated with increased breast cancer incidence      (via sciencedaily.com)     Original source 

Researchers found that living in an area with high levels of particulate air pollution was associated with an increased incidence of breast cancer. The study is one of the largest studies to date looking at the relationship between outdoor air pollution, specifically fine particulate matter, and breast cancer incidence.

New methodology reveals health, climate impacts of reducing buildings' energy use      (via sciencedaily.com) 

Increasing energy efficiency in buildings can save money -- and it can also decrease the carbon emissions and air pollution that lead to climate change and health harms. But the climate and health benefits of reducing buildings' energy consumption are rarely quantified. Now, researchers have developed a new method for calculating the health and climate impacts of these energy savings.

Studies highlight new approaches to addressing climate change      (via sciencedaily.com)     Original source 

Failing to achieve climate mitigation goals puts increasing pressure on climate adaptation strategies. In two new studies, researchers address novel approaches to these issues.

Researchers charting a sustainable course in oceanic carbon capture      (via sciencedaily.com)     Original source 

As researchers around the world race against time to develop new strategies and technologies to fight climate change, a team of scientists is exploring one possible way to directly reduce the amount of carbon dioxide in the environment: Negative emissions technologies (NETs).

Floating sea farms: A solution to feed the world and ensure fresh water by 2050      (via sciencedaily.com)     Original source 

The sun and the sea -- both abundant and free -- are being harnessed in a unique project to create vertical sea farms floating on the ocean that can produce fresh water for drinking and agriculture.

Scientists find evidence of sea star species hybridization      (via sciencedaily.com) 

A new study presents genomic evidence of hybridization between two closely related species of sea stars -- Asterias rubens, the common starfish, and Asterias forbesi, known as Forbes' sea star.

Table salt could be the secret ingredient for better chemical recycling      (via sciencedaily.com)     Original source 

Researchers have shown that table salt outperforms other expensive catalysts being explored for the chemical recycling of polyolefin polymers, which account for 60% of plastic waste. The research shows that sodium chloride could provide a safe, inexpensive and reusable way to make plastics more recyclable. The team also showed that table salt and other catalysts could be used in the recycling of metallized plastic films -- like those used in potato chip bags -- which are currently not recyclable.

Beaver activity in the Arctic increases emission of methane greenhouse gas      (via sciencedaily.com)     Original source 

The climate-driven advance of beavers into the Arctic tundra is causing the release of more methane -- a greenhouse gas -- into the atmosphere. Beavers, as everyone knows, like to make dams. Those dams cause flooding, which inundates vegetation and turns Arctic streams and creeks into a series of ponds. Those beaver ponds and surrounding inundated vegetation can be devoid of oxygen and rich with organic sediment, which releases methane as the material decays.

Mums exposed to air pollution give birth to smaller babies, but living in a greener area may mitigate the risks      (via sciencedaily.com)     Original source 

Women exposed to air pollution give birth to smaller babies, according to new research. The research also shows that women living in greener areas give birth to bigger babies and this may help counteract the effects of pollution.

St Helena's 'liberated' Africans came from West Central Africa between northern Angola and Gabon      (via sciencedaily.com)     Original source 

Between 1840 and 1867, thousands of enslaved Africans who had been 'liberated' from slave ships intercepted by the British Royal Navy were taken to the South Atlantic island of St Helena. But little is written in history books or otherwise known about the lives of these individuals. Now, ancient DNA analyses offer the first direct evidence for the origins of St Helena's liberated Africans.

Bursting air bubbles may play a key role in how glacier ice melts      (via sciencedaily.com)     Original source 

New research has uncovered a possible clue as to why glaciers that terminate at the sea are retreating at unprecedented rates: the bursting of tiny, pressurized bubbles in underwater ice.

Stability inspection for West Antarctica shows: marine ice sheet is not destabilized yet, but possibly on a path to tipping      (via sciencedaily.com)     Original source 

Antarctica's vast ice masses seem far away, yet they store enough water to raise global sea levels by several meters. A team of experts has now provided the first systematic stability inspection of the ice sheet's current state. Their diagnosis: While they found no indication of irreversible, self-reinforcing retreat of the ice sheet in West Antarctica yet, global warming to date could already be enough to trigger the slow but certain loss of ice over the next hundreds to thousands of years.

Ag tech can cut billions of tons of greenhouse gas emissions      (via sciencedaily.com)     Original source 

As the Earth's human population grows, greenhouse gas emissions from the world's food system are on track to expand. A new study demonstrates that state-of-the-art agricultural technology and management can not only reduce that growth, but eliminate it altogether by generating net negative emissions -- reducing more greenhouse gas than food systems add.
