Oceans vital for possibility of alien life
Date: July 20, 2014 Source: University of East Anglia Researchers have made an important step in the race to discover whether other planets could develop and sustain life. New research shows the vital role of oceans in moderating climate on Earth-like planets Until now, computer simulations of habitable climates on Earth-like planets have focused on their atmospheres. But the presence of oceans is vital for optimal climate stability and habitability. The research team from UEA’s schools of Mathematics and Environmental Sciences created a computer simulated pattern of ocean circulation on a hypothetical ocean-covered Earth-like planet. They looked at how different planetary rotation rates would impact heat transport with the presence of oceans taken into account. Prof David Stevens from UEA’s school of Maths said: “The number of planets being discovered outside our solar system is rapidly increasing. This research will help answer whether or not these planets could sustain alien life. “We know that many planets are completely uninhabitable because they are either too close or too far from their sun. A planet’s habitable zone is based on its distance from the sun and temperatures at which it is possible for the planet to have liquid water “Oceans have an immense capacity to control climate. They are beneficial because they cause the surface temperature to respond very slowly to seasonal changes in solar heating. And they help ensure that temperature swings across a planet are kept to tolerable levels. “We found that heat transported by oceans would have a major impact on the temperature distribution across a planet, and would potentially allow a greater area of a planet to be habitable. “Mars for example is in the sun’s habitable zone, but it has no oceans — causing air temperatures to swing over a range of 100OC. Oceans help to make a planet’s climate more stable so factoring them into climate models is vital for knowing whether the planet could develop and sustain life.

Pictured above is the world’s largest indoor farm illuminated by LEDs, which opened this month in Japan. Inside, 18 cultivation racks reach 15 levels high, and are outfitted with 17,500 GE LED light fixtures developed specifically for this facility. The indoor farm can grow lettuce two-and-a-half times faster than an outdoor farm, and is already producing 10,000 heads of it per day. Read more about this breakthrough in modern farming at GE Reports.

The Golden Temple (aka Harmandir Sahib or Darbar Sahib) is situated in Amristar, India and attracts Sikhs from not only all over India but also the entire world. The Golden Temple is the holiest shrine of the Sikh religion, and during the daily meal time an estimated 80,000 people receive free food. The Golden Temple is open not only to the Sikhs but people of all other religions. On average, 350,000-400,000 people visit the Golden Temple every day. On occasions like Amavasya, Sakranth, Diwali, Vaisakhi, and Guruparv, the turnout increases considerably. According to temple officials, around 1 to 1.5 million people visit the temple on these days. The Sikh religion, which emerged in the Punjab region about 500 years ago, rejects the social hierarchies of caste, a precept of Hinduism. The four entrance doors (North, East, South, West) of the Golden Temple signifies Sikhism’s acceptance of people of all walks of life regardless of caste, race, or religion. The principle of equality is enshrined in the langar, where everyone eats together sitting on the floor, regardless of social status. The Golden Temple’s dome is said to be gilded with 750 kilograms of pure gold.

Young Scientists Say They’re Sexually Abused In The Field (NPR)

In a survey of scientists engaged in field research, the majority — 64 percent — said they had personally experienced sexual harassment while at a field site, and 22 percent reported being the victim of sexual assault.
Most of the people reporting harassment or assault were women, and the vast majority were still students or postdocs.
And for female victims, the perpetrator was more likely to be a superior, not a peer. “This is happening to them when they are trainees, when they are most vulnerable within the academic hierarchy,” says evolutionary biologist Katie Hinde , an author on the study in PLOS ONE. Hinde and her colleagues say this could be a factor in the large number of women who enter scientific fields but don’t continue.
