2 . The sea could be the food bowl of the future. In Jervis Bay, south of Sydney, seaweed, which is rich in fibre and omega 3, is grown and harvested.
Pia Winberg is a marine scientist who runs Australia's first food-grade fanned seaweed company. Her crop is grown alongside mussels (贻贝)and is used as an additive in pasta (意大利面)and other products.
Seaweed is also raised in large tanks, where it absorbs carbon dioxide waste from a wheat processing factory. The business is small, but could help to reduce the ecological footprint of traditional farming.
“We used ten percent of seaweed instead of wheat in breads and pastas, we've eliminated a million hectares of land, we've eliminated all of the carbon dioxide emissions associated with that, and we've also reduced the pressures on very precious fresh water.” said Pia Winberg.
Spiny sea urchins (多刺海胆虫)are another blue economy resource. They can destroy marine habitats, but a recent competition for environmental start-ups in Australia, saw them not as a pest but a delicacy (美味).
Martina Doblin, CEO of Sydney Institute of Marine Science, said, “By 2050 we will have some ten billion people on the planet, and about half the food they eat will come from the ocean. So, we really do need to pay attention to the way that we manage the blue economy-generating wealth from the ocean but in a sustainable (可持续的)way.”
Farming at sea has its challenges. Infrastructure (基础设施)has to be sound, as do supply chains and biosecurity. But get these things right, and the ocean might just be the next great economic frontier.

3 . What makes us human？Is it our thoughts？Our emotions？Our behavior？
All of these things make us who we are，but at the center of it all lies the genome — the genes inside our bodies that determine everything from our hair color to our intelligence. But if we could change our genome，would we still be human？
Recently，a group of scientists from the US and South Korea worked together to successfully“edit”a human embryo（胚胎）and remove a genetic mutation（变异）that would have led to heart disease. This was achieved with the help of CRISPR-a gene — editing tool that allows scientists to edit the genome by cutting，changing or adding to parts of it.
Scientists involved in DNA editing are certain about the good of their work，and hope that in the future，diseases could simply be“edited out”.
However，others aren't so sure. People are worried that the science could be used not only to remove life-threatening illness，but also to make a“perfect”baby whose DNA has been chosen to improve its intelligence or other qualities. They say that this is a shallow way of thinking about raising children.
“It makes you think about who we are as people，and it makes you ask if humans should use the kind of power…that is changing human evolution（进化），”Jennifer Doudna of the University of California said.
Still，others worry that DNA editing could be turned into an expensive service that would only be available to the people who could afford it. That might mean the rich would be given another advantage in a world where they already have plenty of them.
“You could find wealthy parents buying the technology for their children, leading to even greater inequality than we already live with,”Marcy Darnovsky, director of the San Francisco Center for Genetics and Society, said.

4 . What will higher education look like in 2050? That was the question addressed Tuesday night by Michael Crow, president of Arizona State University.
“We’re at the end of the fourth wave of change in higher education,” Crow began, arguing that research universities followed the initial establishment of higher education, public colleges, and land-grant schools in the timeline of America.
In less than a half-century, he said, global market competition will be at its fastest rates of change ever, with several multi-trillion-dollar economies worldwide. According to a recent projection, the nation’s population could reach 435 million, with a large percentage of those residents economically disadvantaged. In addition, climate change will be “meaningfully uncontrollable” in many parts of the world.
The everyday trends seen today, such as declining performance of students at all levels, particularly in math and science, and declining wages and employment among the less educated, will only continue, Crow maintained, and are, to say the least, not contributing to fulfilling the dream of climbing the social ladder mobility, quality of life, sustainable environment, and longer life spans that most Americans share.
“How is it that we can have these great research universities and have negative-trending outcomes?” Crow said in a talk “I hold the universities accountable. … We are part of the problem.”
Among the “things that we do that make the things that we teach less learnable,” Crow said, are the strict separation of disciplines, academic rigidity, and conservatism, the desire of universities to imitate schools at the top of the social ranks, and the lack of the computer system ability that would allow a large number of students to be educated for a small amount of money.
Since 2002, when Crow started being in charge at Arizona State — which he calls the “new American university” — he has led more than three dozen initiatives that aim to make the school “inclusive, scalable, fast, adaptive, challenge-focused, and willing to take risks.”
Among those initiatives were a restructuring of the engineering and life sciences schools to create more linkages between disciplines; the launch of the School of Earth and Space Exploration and the School of Sustainability; the start of a Teachers College to address K-12 performance and increase the status of the Education Department at the university; and broadened access, increasing the freshman class size by 42 percent and the enrollment of students living below the poverty line by 500 percent.
Universities must start, Crow noted, “by becoming self-reflective architects, figuring out what we have and what we actually need instead of what legend tells us we have to be.” Research universities today have “run their course,” he added. “Now is the time for variety.”
During a discussion afterward, Crow clarified and expanded on some of his points. He discussed, for example, the school’s distance-learning program. “Nearly 40 percent of undergraduates are taking at least one course online,” he said, which helps the school to keep costs down while advancing interactive learning technologies.
He said that Arizona State is working to increase the transfer and completion rates of community-college students, of whom only about 15 percent, historically, complete their later degrees. “We’ve built a system that will allow them to track into universities,” particularly where “culturally complex barriers” beyond finances limit even the most gifted students.
