Asteroid that killed dinosaurs also intensified volcanic eruptions - study
Research on the Deccan Traps in India reveals massive rise in lava flows around time of impact of Mexico’s Chicxulub crater 65m years ago, increasing the catastrophe for ecosystemsThe asteroid that slammed into Earth and heralded the doom of the dinosaurs triggered a surge in volcanic eruptions that made the catastrophe even worse, researchers claim.Scientists analysed prehistoric lava flows in India and found that soon after the massive impact, volcanic eruptions became twice as intense, throwing out a deadly cocktail of sulphur dioxide and carbon dioxide.

No evidence 'cocktail of everyday chemicals' causes cancer
ConclusionThis systematic review has identified 85 chemicals found in the environment that have the potential to affect different stages in the development of cancer. The researchers say this is intended as a starting point, so that future research can look at what effect these chemicals may have when there is exposure to more than one. This is a new approach to understanding the risk that various chemicals may have.The study did not find that these chemicals cause cancer, but that they have the potential to make changes to cells, which would then create particular characteristics of cancer, such as increased uncontrolled ...

Earth's Mysteriously Light Core Brims With Sulphur
New research from the European Association of Geochemistry indicates that the Earth's core contains large deposits of sulphur, estimated to be upwards of 8.5 x 1018 tonnes. Published in the Geochemical Perspectives Letters in June 2015, this estimation far surpasses the current amount of sulphur on the Earth's surface and based on recent estimations, is around 10 percent of the Moon's mass.
This is the first time geologists have found any conclusive data for sulphur in the Earth's core, adding more support to the theory that the Moon was formed from a collision between a young Earth and a large planet-sized object.

Massive Eruption Of Japan's Mount Shindake Volcano Caught On Camera
Japanese residents fled the remote southern island of Kuchinoerabu on Friday following the eruption of Mount Shindake -- and the spectacular eruption was captured on video.
Mount Shindake spewed black clouds as high as 5.6 miles into the sky as authorities evacuated nearly 140 people from the island, with one man reportedly suffering minor burns but all others believed to be safe. Video captured by the Japan Meteorological Agency and published by the Japanese public broadcaster NHK shows the initial explosion mushrooming into a towering cloud of ash.
Watch the full video, above.

Can volcanoes tackle climate change?
Two hundred years ago a volcanic eruption cooled the Earth. Could it help us tackle global warming today?The island of Sumbawa in what is now Indonesia began to crack apart 200 years ago this week. On 10 April 1815, an explosion that could be heard a thousand miles away announced the largest volcanic eruption in recorded history. Mount Tambora, once among the highest peaks in the East Indies, was blown in half. Thousands in the immediate vicinity were killed by lava, wind, ash, fire and tsunamis, but the volcano’s effects echoed far further and longer. The force of the explosion catapulted millio...

Study finds link between air pollution and stroke risk
Conclusion
This study showed a clear link between rises in gas and particle pollution and the chances of being admitted to hospital or dying because of a stroke. The researchers showed the link was strongest on the day of exposure to raised pollution levels.
But this study has some limitations. While systematic reviews are a good way to summarise all the research that has been published on a topic, they are only as good as the individual studies they include.
About two-thirds of the studies used a time series design, which the researchers say is less effective in taking account of trends such as the season of year, rathe...

India Air Pollution Cutting 660 Million Lives Short By 3 Years
NEW DELHI (AP) — India's filthy air is cutting 660 million lives short by about three years, according to research published Saturday that underlines the hidden costs of the country's heavy reliance on fossil fuels to power its economic growth with little regard for the environment.
While New Delhi last year earned the dubious title of being the world's most polluted city, India's air pollution problem is extensive, with 13 Indian cities now on the World Health Organization's list of the 20 most polluted.
That nationwide pollution burden is estimated to be costing more than half of India's pop...

What Does A Comet Smell Like? Rosetta Probe Reveals This Space Rock Frickin' Stinks
Mix the aroma of rotten eggs with a whiff of horse stables, throw in a hint of ammonia and formaldehyde, and viola! You've got eau de Comet 67P/Churyumov-Gerasimenko.
Scientists at the University of Bern in Switzerland recently discovered the comet's pungent scent by analyzing a mixture of molecules detected in the comet's coma, the cloud of particles and gases around the space rock's nucleus.
The molecules were collected by an instrument aboard the Rosetta spacecraft, which has been flying in tandem with the comet. The instrument, called ROSINA, consists of two mass spectrometers and a pressure sensor.

Air pollution linked to irregular heartbeat and lung blood clots
Conclusion
This was a large national study that looked in detail at links between people's short-term exposure to air pollutants and national records on hospital admissions for heart attack, emergency admissions for all cardiovascular problems, and deaths from cardiovascular disease.
The study had some limitations – for example, as the authors say, it did not include heart attacks that took place before hospital admission. It also used fixed monitoring sites, which may not accurately reflect personal exposure to air pollution.
For the public, the results of this study are probably confusing. That's because the resear...
