Potatoes can grow on Mars : Study

CubeSat indicator experiments prove potatoes can grow on Mars. The International Potato Center (CIP) launched a series of experiments to discover if potatoes can grow under Mars atmospheric conditions.

Scientists with the CIP created Mars-like growing conditions inside a CubeSat designed by engineers at the University of Engineering and Technology (UTEC) in Lima, Peru and advice provided by the National Aeronautics and Space Administration in Ames Research Center (NASA ARC), California. The potato plants inside the experimental box are reportedly thriving.

The findings show potatoes can also grow under extreme conditions on Earth too.

The box mimics the day-night patterns of Mars, as well as its temperature, air pressure and atmospheric composition. Sensors inside the hermetically-sealed box monitor the progress of the tubers.

“Growing crops under Mars-like conditions is an important phase of this experiment,” Julio Valdivia-Silva, a research associate with the SETI Institute, said in a news release.

“If the crops can tolerate the extreme conditions that we are exposing them to in our CubeSat, they have a good chance to grow on Mars. We will do several rounds of experiments to find out which potato varieties do best. We want to know what the minimum conditions are that a potato needs to survive.”

The CubeSat houses a container holding soil and the tuber. Inside this hermetically sealed environment the CubeSat delivers nutrient rich water, controls the temperature for Mars day and night conditions and mimics Mars air pressure, oxygen and carbon dioxide levels.

Sensors constantly monitor these conditions and live streaming cameras record the soil in anticipation of the potato sprouting.

One advantage, potato has great genetic capacity for adaptation to extreme environment, according to CIP potato breeder Walter Amoros.

“The results indicate that our efforts to breed varieties with high potential for strengthening food security in areas that are affected, or will be affected by climate change, are working,” Amoros said.

Google changes YouTube revenue rule

KATHMANDU — Google is making the biggest changes ever to the advertising rules on the most popular video platform, YouTube, since the video site’s inception, an attempt to clean up its content and answer persistent complaints from advertisers.

The world’s largest video platform will kick thousands of people out of its ad revenue-sharing program, and will make it much harder for new ones to get into the program. The change is among one of YouTube’s responses to a year of criticism it has generated for a series of scandals involving questionable and offensive content that has appeared on the site.

YouTube will now impose stricter rule for video types that can earn money on the site and will introduce a new vetting process for the top-shelf videos it offers advertisers, the company said Tuesday in a statement.

YouTube’s new rules require anyone who wants to generate revenue on the platform to first generate 4,000 hours of ‘watchtime’ over a 12-month period, and to attract at least 1,000 subscribers.

That replaces a lower hurdle of 10,000 lifetime views, which the site instituted last spring, after a first wave of negative stories about rogue content.

YouTube, in a blog post, says the new rules will affect ‘a significant’ number of its user-created channels, but won’t provide an official tally.
