Around 1.4 Billion Years Ago One Day Only Consisted Of 18 Hours

New Study Proves that Days Were Shorter in The Past. According to a new study, Moon is constantly getting away from Earth, and its distance has a significant effect on the duration of hours that make up for a full day on the Earth. Among other different reasons, Moon’s existence and its distance from Earth make our planet an ideal place where biological life can … Continue reading Around 1.4 Billion Years Ago One Day Only Consisted Of 18 Hours

Bacteria-Based Sensor Could Detect Oil and Gas Leaks

Scientists are developing a “living sensor” that eats hydrocarbons to monitor the country’s extensive network of petroleum pipelines. More than 212,000 miles of oil and gas pipelines traverse the United States, transporting about 16 billion barrels of crude oil, refined petroleum products and liquefied natural gas each year. Thousands more miles of pipeline branch across the ocean floor. Monitoring the extensive network for leaks is a monumental … Continue reading Bacteria-Based Sensor Could Detect Oil and Gas Leaks

Air pollution to blame for traffic accidents: study

| 10/04/2016 London: Air pollution may be responsible for hundreds of car accidents a year, as toxic air may impair driver fitness, a new UK study has found. Researchers from the London School of Economics divided the UK into a grid of 32 areas each covering about 7,700 square kilometres and mapped accidents to the level of air pollution between 2009 and 2014. They found … Continue reading Air pollution to blame for traffic accidents: study

UK air quality shows little improvement over past 20 years, says study

| 08/30/2016 There has been little improvement in air quality over the past 20 years as transport planners focus on preventing road deaths, according to a study. Two university academics set out to try to understand why there has been little improvement in air pollution concentrations from road transport since the UK signed up to international air quality standards in 1995, as part of the … Continue reading UK air quality shows little improvement over past 20 years, says study

Global warming is melting the Greenland Ice Sheet, fast

| 08/27/2016 A new study measures the loss of ice from one of world’s largest ice sheets. They find an ice loss that has accelerated in the past few years, and their measurements confirm prior estimates. As humans emit heat-trapping gases, we expect to see changes to the Earth. One obvious change to be on the lookout for is melting ice. This includes ice atop … Continue reading Global warming is melting the Greenland Ice Sheet, fast

Human-induced climate change began earlier than previously though

| 08/25/2016 Continents and oceans in the northern hemisphere began to warm with industrial-era fossil fuel emissions nearly 200 years ago, pushing back the origins of human induced climate change to the mid-19th century. The first signs of warming from the rise in greenhouse gases which came hand-in-hand with the Industrial Revolution appear as early as 1830 in the tropical oceans and the Arctic, meaning … Continue reading Human-induced climate change began earlier than previously though

Study measures methane discharge from Arctic permafrost

| 08/25/2016 The project, led by UAF researcher Katey Walter Anthony, studied lakes in Alaska, Canada, Sweden and Siberia where permafrost thaw surrounding lakes led to lake shoreline expansion during the past 60 years. Using historical aerial photo analysis, soil and methane sampling, and radiocarbon dating, the project quantified for the first time the strength of the present-day permafrost carbon feedback to climate warming. Although … Continue reading Study measures methane discharge from Arctic permafrost
