Aerosols, tiny solid and liquid particles suspended in the atmosphere, impact the environment by affecting air quality and alter the Earth’s radiative balance by either scattering or absorbing sunlight to varying degrees. What impact does climate change, induced by greenhouse gases (GHGs), have on the aerosol “burden”–the total mass of aerosols in a vertical column of air? Past research done […]

Scientists believe is a new whale species is doing the exact opposite of other whales. It is being as heard as it is seen. Recordings taken near the polar continent captured a strange, never-before-heard whale sound — a signal they are calling “Antarctic BW29”. Researchers say that they located the signal 1,000 times in 14 separate recordings. The unique sounds […]

Buried deep in the Antarctic ice, an observatory has spotted ghostly, nearly massless particles coming from inside our galaxy and points beyond the Milky Way. Finding these cosmic neutrinos not only confirms their existence but also sheds light on the origins of cosmic rays, the researchers said. The IceCube Neutrino Observatory is made up of 86 shafts dug 8,000 feet […]

The US could reduce greenhouse gas emissions from electricity generation by 80% below 1990 levels within 15 years just by using renewable sources such as wind and solar energy, according to a former government research chief. The nation could do this using only technologies available right now, and by introducing a national grid system connected by high voltage direct current […]

Scientists in the US who have been checking on the health of the Arctic over the last year are worried by what they’ve learned: it’s warmer, has less ice, and some of its animals and fish are facing new stresses. And in a surprise finding , which they cannot yet explain, the scientists discovered that green vegetation over much of […]

We’ve heard a lot about the negative effects of climate change in the arctic and subarctic. But some Alaskans, like farmer Tim Meyers, are seeing warming temperatures as an opportunity. Now that potato harvest is underway at his Bethel farm, Meyers uses a giant potato washer, like a washing machine for root vegetables, to clean California white potatoes. They’re some […]

Researchers tracked the blood glucose levels of more than 2,000 older adults for seven years and found that those who had high glucose levels—but not diabetes—were nearly 20 percent more likely to develop dementia than those with low levels. […]

Eating fruits and vegetables contaminated with pesticide residue may lower men’s sperm counts, a new study has found. Researchers at Harvard University surveyed 155 men who had sought fertility treatment about their eating habits. They found that subjects who ate more soft, thin-skinned fruits and vegetables such as apples, grapes, and potatoes—foods that tend to contain high levels of pesticide […]
