Iowa Rep. Steve King’s claims on water quality get SciChecked – @factcheckdotorg

scichecksquare_4-e1430162915812

SciCheck spills the scientific T on water quality data – and schools Rep. Steve King on his recent claims (including the snarky, but hilarious point that ‘bison’ is more scientifically accurate than ‘buffalo’).

During a recent congressional hearing, Rep. Steve King of Iowa underestimated what scientists know about the relationship between farming practices and water quality.

  • King said scientists don’t know about the quality of water in the U.S. “when the buffalo roamed” because there were “no water quality tests then.” Pre-1900 water quality data is relatively scarce, but experts can use techniques from paleolimnology to evaluate past water quality.
  • He implied that this lack of “baseline” data prevents scientists from knowing whether applications of crop fertilizer are “too much.” But experts say they don’t need 19th century data to know fertilizers have negatively impacted water quality. The 20th century provides plenty of evidence.

To start, the term “bison” is scientifically more accurate than “buffalo” when referring to North American populations.

Claims about the water in Flint, MI get SCICHECKED! #science

scichecksquare_4-e1430162915812

Scicheck finds many false claims about the water in Flint Michigan. Check the article – highlights below:

A Michigan health official told Congress that his department’s “initial analysis” showed blood lead levels in Flint children in the summer of 2014 were “within range of years before.” That’s false. That analysis concluded blood lead levels “were higher than usual” from July to September 2014, shortly after the city switched its water supply.

On April 25, 2014, the city of Flint began using the Flint River as its water source, as reported in the Detroit Free Press. But the Flint River has particularly corrosive water, which led to high levels of lead leaching into the water from many of the city’s dated pipes. Soon after the water supply switch, Flint residents began complaining about the color of the water, rashes and other issues.

Then, in July 2015 the Michigan Department of Environmental Quality told Michigan Gov. Rick Snyder that issues with water contamination in Flint were limited to one house and not widespread. At the same time, the Michigan Department of Health and Human Services claimed the elevated blood lead levels in children followed a normal seasonal trend.

The link between Flint’s water switch and elevated blood lead levels in children wasn’t confirmed until two independent researchers, Marc Edwards and Mona Hanna-Attisha, each put forth their own analyses in September 2015.

Liquid Water confirmed on Mars!! #NASA

From NASA today:

New findings from NASA’s Mars Reconnaissance Orbiter (MRO) provide the strongest evidence yet that liquid water flows intermittently on present-day Mars.

Using an imaging spectrometer on MRO, researchers detected signatures of hydrated minerals on slopes where mysterious streaks are seen on the Red Planet. These darkish streaks appear to ebb and flow over time. They darken and appear to flow down steep slopes during warm seasons, and then fade in cooler seasons. They appear in several locations on Mars when temperatures are above minus 10 degrees Fahrenheit (minus 23 Celsius), and disappear at colder times.

“Our quest on Mars has been to ‘follow the water,’ in our search for life in the universe, and now we have convincing science that validates what we’ve long suspected,” said John Grunsfeld, astronaut and associate administrator of NASA’s Science Mission Directorate in Washington. “This is a significant development, as it appears to confirm that water — albeit briny — is flowing today on the surface of Mars.”

These downhill flows, known as recurring slope lineae (RSL), often have been described as possibly related to liquid water. The new findings of hydrated salts on the slopes point to what that relationship may be to these dark features. The hydrated salts would lower the freezing point of a liquid brine, just as salt on roads here on Earth causes ice and snow to melt more rapidly. Scientists say it’s likely a shallow subsurface flow, with enough water wicking to the surface to explain the darkening.

Dark narrow streaks called recurring slope lineae emanating out of the walls of Garni crater on Mars. The dark streaks here are up to few hundred meters in length. They are hypothesized to be formed by flow of briny liquid water on Mars.

Imagine your house sinking 2 inches per month!! Drought in California is having that impact in valleys! #climate

[tweet https://twitter.com/NASA/status/634189611242270720]

The valleys in California are sinking at truly unbelievable rates in response to massive drought and as groundwater is being pumped out. Some areas are sinking almost 2 inches per month!!!  More details at the NASA website.

As Californians continue pumping groundwater in response to the historic drought, the California Department of Water Resources today released a new NASA report showing land in the San Joaquin Valley is sinking faster than ever before, nearly 2 inches (5 centimeters) per month in some locations.

Turns out if you want to find out where the water is on Earth, gravity can help. Specifically, if you want to find out where water is below the Earth’s surface, satellites can use the force of gravity to figure that out… from space. Which is SO COOL.

If you don’t know what you want to be when you grow up, be a scientist. this stuff is so cool.

Clean-water activist to swim toxic #Gowanus Canal for awareness – @SwimWithSwain #EarthDay #NoPlaceLikeHome

[tweet https://twitter.com/SwimWithSwain/status/589994105746358272]

For Earth Day today, clean-water activist Christopher Swain will swim through the dirty, toxic, disgusting, disease-ridden Gowanus Canal in New York City. More info here!

Swain announced today that he will hop into the Canal on April 22 covered from head to toe in protective gear to keep his skin, mouth, eyes, and ears free of the murky waters that famously hides victims of the mob, is covered with oil, laced with heavy metals, flooded with millions of gallons of raw sewage every year, and even has gonorrhea.

The Canal is also home to schools of Coney Island Whitefish as well as a 10-to-15-foot base of mercury-laden “black mayonnaise,” and despite the fact that things have gotten less smelly since a flushing tunnel began pumping oxygen-laden water into it back in 1999, the federal cleanup is still more than a decade from completion.

Just in case this GIF and video aren’t already cool enough for you… there is a 3D version!!!!

Space Station Astronauts Grow a Water Bubble in Space from NASA’s Marshall Center

During Expedition 40 in the summer of 2014, NASA astronauts Steve Swanson and Reid Wiseman — along with European Space Agency astronaut Alexander Gerst — explored the phenomenon of water surface tension in microgravity on the International Space Station. The crew “submerged” a sealed GoPro camera into a floating ball of water the size of a softball and recorded the activity with a 3-D camera. (Video: NASA)

Ramadan and the World Cup: No problemo or a death wish?

Have you ever been to the gym? Or for a run? Or a bike ride? Or played soccer? Football? Basketball? You get hot, sweaty, and thirsty…  Now imagine doing that strenuous physical activity in tropical, humid brazil right now with average temperatures above 80F.

Now imagine you can’t have any water during that time. None.

With the onset of Ramadan, the holy month for Islam, a lot of people have been questioning the effects of this holiday on the muslim soccer players.  During Ramadan, followers are not permitted to eat OR DRINK during day light hours.  That means no water during the soccer games for athletes observing Ramadan.

Due to hot and humid conditions, this world cup has issued athletes take required water breaks in the middle of the games.  Yet, some of the most fantastic athletes, during one of the biggest most prestigious tournaments in the world, when they are expected to be at the height of their performance, will not be drinking water at all… due to religious reasons.  No water?! Surely that is insane?

But according to an article in the NYTimes, apparently fasting and not drinking water will have minuscule effect on the players.  Ron Maughan, a professor of sports nutrition at Loughborough University in England, conducted a study to examine the effects of fasting on athletes (prior to the 2012 London Olympics), and concluded that, “It might be fair to say there is no large effect.”  Apparently FIFA has also commissioned some studies to determine the effects of fasting:

“We made an important study with the doctor of the Algerian Football Federation, and it was very positive,” said Dr. Michel D’Hooghe, the chairman of FIFA’s medical committee and a member of its executive committee. “If you do it intelligently, then you can adapt perfectly. Before the sun comes up, they have enough hydration to go on through the whole day.”

Really?! So it is totally OK not to stay hydrated THROUGHOUT the games?! This all seems a little fishy to me.  Especially with the overwhelming evidence supporting the importance of hydration during athletic activity, ESPECIALLY in the heat (A simple google search, another simple google search).  Furthermore, irregular hydration and fasting has consequences for proper sleep habits as well… and of course, proper sleep and rest is incredibly important for athletic performance (WebMD).   In an article in the Huffington PostAli Zogbhi, vice president of the Federation of Muslim Associations in Brazil, said on Brazilian TV: “Science has already proved that if you do physical exercise without eating you experience serious problems. Therefore, it is more sensible to allow players to not fast during this period.”

The good news is that oftentimes, for special circumstances, exemptions can be made for followers of Ramadan.  Other times, followers can essentially “take a rain check,” and skip a few days of fasting, and make up those days at a later time.

The World Cup is a big deal, and for some of these players, this is there one and only moment to shine.  Hydration and nourishment are essential for peak performance ability.  A lot of athletes take their religion seriously… but for the sake of their health and career, I hope they make an exception during this World Cup and continue drinking water!!!
