But the frogs have managed to sidestep this potentially damaging side effect through other genetic tweaks, researches reported in September,22.While other studies have identified genetic changes that give frogs resistance to particular toxins, this study “lets you look under the hood”. Many poison dart frogs carry cocktails of toxic alkaloid molecules in their skin as a defense against predators.These toxins, picked up through the frogs’ diets, vary by species. Here, researchers studied frogs that carry epibatidine, a substance so poisonous that just a few millionths of a gram can kill a mouse. Previous studies have shown that poisonous frogs have become resistant to the toxins the amphibians carry by messing with the proteins that these toxins bind to in the body. Switching out certain proteins. Building blocks, or amino acids, changes the shape of the protein, which can prevent toxins from latching on. But making that change could have unintended side effects, too, says study coauthor Rebecca Tarvin, an evolutionary biologist at the University of Texas at Austin.]]> 2017-11-08 16:30:01 UTC https://padlet.com/19stefanok/bc1y76w1rwki/wish/204905126 19stefanok https://padlet.com/19stefanok/bc1y76w1rwki/wish/204905238 in 2015 it was stated that 9 million people died due to pollution on Earth. Most of those deaths are concentrated among the world’s poorest populations, according to a study published online October 19th. In fact, 25 percent of premature deaths could be attributed to pollution, especially in the air. More than half of the global deaths from air pollution in 2015 occurred in India and China. An estimated 9 million people died from pollution exposure in 2015, the commission reports. An estimated 9 million people died from pollution exposure in 2015, the commission reports. China has one of the biggest pollution issues in the world they all wear air masks when walking in the main cities where the air is so bad for you to breath in everyday. ]]> 2017-11-08 16:30:11 UTC https://padlet.com/19stefanok/bc1y76w1rwki/wish/204905238 19stefanok https://padlet.com/19stefanok/bc1y76w1rwki/wish/204905333 This article is all about that chicken meat has been been seen having outbreaks of drug-resistant Salmonella infections in humans, and ailing chickens living in crowded conditions and never seeing the light of day. This is causing many to get sick and can automatically kill the chickens before they even get to the places they were being shipped to go. Farmers began using the drugs after studies in the 1940s showed that antibiotics boosted muscle mass. For chickens, that meant the birds got bigger and grew faster with less feed. ]]> 2017-11-08 16:30:20 UTC https://padlet.com/19stefanok/bc1y76w1rwki/wish/204905333 19stefanok https://padlet.com/19stefanok/bc1y76w1rwki/wish/204905419 Boston has said that there is a lawn that helps the environment and doesn't  need to be moved towards turned the ocean. There are meadows of under water  sea grass plants that might be able to lower the levels of harmful bacteria in nearby ocean waters.  at the annual meeting of the American Association for the Advancement of Science. That could make the whole ecosystem — from corals to fish to humans — healthier.Not truly a grass, sea grasses are flowering plants with long, narrow leaves. They grow in shallow ocean water, spreading into vast underwater lawns. They are to be known as marine powerhouses. They are one of the largest stores of carbon in the ocean. They improve water quality and are also good for removing excess nitrogen and phosphorus from coastal waters. But now, it seems, they might take away harmful bacteria, too. ]]> 2017-11-08 16:30:29 UTC https://padlet.com/19stefanok/bc1y76w1rwki/wish/204905419 19stefanok https://padlet.com/19stefanok/bc1y76w1rwki/wish/204905532 Neonicotinoid pesticides are turning up in honey on every continent with honeybees. The testing that has been placed on these bees took place just recently and told scientists that the bees getting exposed to these chemicals are ending up affecting the health of them. The pesticides are used on many kinds of crops grown in different climates, but traces of the chemicals showed up even in honey from remote islands with very little agriculture.  A man named Mitchell and his team crowd sourced 198 honey samples from around the world, asking friends and colleagues to send local honey from their home countries or vacation destinations. What he found from his results was shocking to all he said that The presence of pesticides varied regionally — 86 percent of the North American samples contained at least one of the five commonly used neonicotinoids. This is affecting the honey we eat and the bee community causing a big drop in honey production and bees in general. ]]> 2017-11-08 16:30:39 UTC https://padlet.com/19stefanok/bc1y76w1rwki/wish/204905532 19stefanok https://padlet.com/19stefanok/bc1y76w1rwki/wish/204905636 The East Antarctica consists of the largest glacier on planet Earth. This glacier has been tracked and is been noted that it has been pushed by the inland winds. These currents are indeed warm water ones and are stuck under melting away this well known glacier. The first signs at this incident happening was founded last year by scientists when they noticed the difference in size and weight. The ice was starting the melt causing it to become weak and thin. So surprisingly the wind  patterns have more to do with the glaciers melting then pollution and gas in the air that harms these. ]]> 2017-11-08 16:30:47 UTC https://padlet.com/19stefanok/bc1y76w1rwki/wish/204905636
