#Micromotors Could Help Reduce Ocean Pollution The buildup of carbon dioxide, a major greenhouse gas, is increasingly impacting oceans around the world, making waters more acidic and threatening sea life.
Nanoengineers at the University of California, San diego have made a splash in trying to overcome this obstacle.
Theye developed tiny motors smaller than the width of a human hair that can autonomously travel through oceans to remove CO2 and convert it to a usable solid form.
the micromotors removed up to 90 percent of the carbon dioxide from a solution of deionized water.
In a seawater solution the micromotors removed 88 percent of the carbon dioxide in the same timespan. n the future, we could potentially use these micromotors as part of a water treatment system,
like a water decarbonation plant, said Kevin Kaufmann, an undergraduate researcher and a co-author of the study.
The motors are six-micrometer-long tubes with an outer polymer surface that holds a chemical enzyme carbonic anhydrase designed to speed up the reaction between carbon dioxide and water and form bicarbonate.
generating oxygen bubbles that propel the motors through the water. However, scientists are currently exploring ways to cut back on the two to four percent of hydrogen peroxide used as they focus on alternatives to use water itself to fuel the motors.
Going Blue: Ocean Landscapes Need Protectiononce the moters complete their mission, they can be recovered from the water
and reused for future applications. f the micromotors can use the environment as fuel, they will be more scalable, environmentally friendly and less expensive, Kevin Kaufmann,
an undergraduate researcher and co-author of the study, said in a press release, adding that in the future, these micromotors could likely be used as part of a water treatment system,

#Nasa Finds Liquid Water On Mars In a Mars-related press conference this morning NASA has announced that nder certain circumstancesliquid water has been found on Mars. ars is not the dry arid planet that we thought of in the past,
but scientists had thought the atmosphere of Mars was too thin for liquid water to be possible.
These streaks had been noticed to vary following temperature changes on the surface leading to a hypothesis that the substance was water.
The presence of perchlorate in the Martian soil improves the stability of liquid water on the surface of Mars,
NASA scientists said today enabling the liquid water to exist for longer before either freezing as the temperature on the planet drops,
This means that Marswater is riny rather than ure The viability for life to exist in this water is ot clearat this stage,
NASA added although the presence of liquid water itself gives a huge boost to that search. y feeling
water is an essential ingredient for life This is tremendously exciting. We haven been able to answer the question oes life exist beyond Earth,
but finding water is critical to that. We now have, I think, great opportunities to be in the right locations on Mars to thoroughly investigate that,
The presence of liquid water on Mars could also help any future human mission to the planet
and now we know there is liquid water on the surface of this cold, desert planet,

#Signs of liquid water found on surface of Mars, scientists say Despite its reputation as a forebodingly dusty, desolate and lifeless place,
Scientists reported on Monday definitive signs of liquid water on the surface of present-day Mars,
"That's a direct detection of water in the form of hydration of salts,"Mcewen said."
"There pretty much has to have been liquid water recently present to produce the hydrated salt.""By"recently,"Mcewen said he meant"days, something of that order."
"Although young Mars was inundated by rivers, lakes and maybe even an ocean a few billion years ago,
Scientists have known long that large amounts of water remain but frozen solid in the polar ice caps.
There have been fleeting hints of recent liquid water, like fresh-looking gullies, but none have proved convincing.
In 2011, Mcewen and colleagues discovered in photographs from the Mars Reconnaissance Orbiter dark streaks descending along slopes of craters, canyons and mountains.
Scientists suspected that water played a critical role in the phenomenon, perhaps similar to the way concrete darkens when wet, with no change in the shape of the surface,
"It's very definitive there is some sort of liquid water, "Ojha said. The perchlorate salts lower the freezing temperature,
and the water remains liquid. The average temperature of Mars is about minus 70 degrees Fahrenheit,
For one, scientists do not know where the water is coming from.""There are two basic origins for the water:
from above or from below,"Mcewen said. The perchlorates could be acting like a sponge, absorbing moisture out of the air,
Liquid water is considered one of the essential ingredients for life, and its presence raises the question of whether Mars,

#Ancient Mars had long-lasting lakes, rivers: Nasa Mars harboured long-lasting lakes and water streams about 3. 8 to 3. 3 billion years ago,
boosting the odds that life may have existed once on the Red planet, scientists, including one of Indian-origin,
have found. Using data from the Curiosity rover, Nasa's Mars science laboratory/Curiosity team has determined that, long ago,
water helped deposit sediment into Gale crater, where the rover landed more than three years ago. The sediment deposited as layers that formed the foundation for Mount Sharp,
and lakes existed at some point between about 3. 8 to 3. 3 billion years ago,
The findings build upon previous work that suggested there were ancient lakes on Mars, and add to the unfolding story of a wet Mars, both past and present.
Last month, Nasa scientists confirmed current water flows on Mars."It's clear that the Mars of billions of years ago more closely resembled Earth than it does today.
Others focused on the possibility that sediment layers were deposited in ancient lakes. The latest results indicate that these wetter scenarios were correct for the lower portions of Mount Sharp.
Based on the new analysis, the filling of at least the bottom layers of the mountain occurred mostly by ancient rivers and lakes over a period of less than 500 million years."
as well as places where streams appear to have emptied out into bodies of standing water, "Vasavada said."
"The prediction was that we should start seeing water-deposited, fine-grained rocks closer to Mount Sharp.
we're seeing finely laminated mudstones in abundance that look like lake deposits, "he said. The mudstone indicates the presence of bodies of standing water in the form of lakes that remained for long periods of time,
possibly repeatedly expanding and contracting during hundreds to millions of years. These lakes deposited the sediment that eventually formed the lower portion of the mountain.
The research was published in the journal Science e
