Article From The Big Think
There are certain things that we accept as facts with no alternatives. The Earth is becoming warmer due to human action. The diversity of life arose by evolution. Politicians who devalue expertise risk making decisions that do not reflect reality and must be held accountable. An American government that ignores science to pursue ideological agendas endangers the world.
These are the words written by the organizers of the upcoming Scientists’ March on Washington. The date for the march is not yet set, but it will likely take place, summoning a sea of smart people with a love for science — like you — and the pursuit of knowledge.
The march grew out of a discussion on Reddit, with a private Facebook group and Twitter account launched on Monday, January 23. In just a couple of days, the group had 300,000 members. Their public Twitter account has 288,000 followers and their public Facebook page has 20,832 followers as of this writing. You can also sign up to receive email updateson the march. The organizers are also looking for help.
The scientific community has been under attack for a while now by Christians who take issue with Darwinian evolution, preferring the Bible’s account. And while nobody wants climate change to be real, it is, though some would rather ignore the supporting evidence and overwhelming consensus of the scientific community to reinforce their own denial. There’s a growing cult of ignorance in which people pride themselves on their lack of scientific knowledge, and it threatens to plunge us all into a new dark age.
Nowhere is this being felt more acutely than in the U.S., where the new Trump administration — along with many Congressional Republicans — is firm in its denial of climate change and in their desire to control the national conversation on a range of scientific issues. Through anti-science appointments, the barring of publications from federal science agencies, and the freeze of all research funding, it all amounts to an unprecedented attack on fact-based knowledge. It’s the chilling — and terrifying — first step of a process in which truth can become whatever a group of politicians say it is.
To protect their findings, and the truth, scientists began frantically grabbing and preserving climate change data before the administration came into office. Since the inauguration, employees of muzzled departments have started rogue Twitter accounts as an uncensored outlet for information — unfortunately, many of these have now been handed over to others as employees fear for their jobs.
Caroline Weinberg, one of the march’s organizers, says, “This is not a partisan issue. People from all parts of the political spectrum should be alarmed by these efforts to deny scientific progress. Scientific research moves us forward and we should not allow asinine policies to thwart it.” She adds that science lovers are as welcome as scientists to participate in the march.
It’s not the first time scientists have tried to act as a conscience of a wayward federal government. For example, scientists were key players in the 310,000-person 2014 People’s Climate March. And Harvard science historian Naomi Oreskes, speaking to KQED, reminds us, “It is the scientists who mobilized against the arms race in the late 1950s and 1960s. So that tells you how scientists feel now. This is an existential threat.”
This is an excerpt from an article appearing in the August 20, 2016, Science News with the headline, “Quenching society’s thirst: Desalination may soon turn a corner, from rare to routine.”
When Khaled Moustafa looks at a beach, he doesn’t just see a place for sunning and surfing. The biologist at the National Conservatory of Arts and Crafts in Paris sees the future of farming.
In the April issue of Trends in Biotechnology, Moustafa proposed that desalination could supply irrigation water to colossal floating farms. Self-sufficient floating farms could bring agriculture to arid coastal regions previously inhospitable to crops. The idea, while radical, isn’t too farfetched, given recent technological advancements, Moustafa says.
Floating farms would lay anchor along coastlines and suck up seawater, he proposes. A solar panel–powered water desalination system would provide freshwater to rows of cucumbers, tomatoes or strawberries stacked like a big city high-rise inside a “blue house” (that is, a floating greenhouse).
Each floating farm would stretch 300 meters long by 100 meters wide, providing about 3 square kilometers of cultivable surface over only three-tenths of a square kilometer of ocean, Moustafa says. The farms could even be mobile, cruising around the ocean to transport crops and escape bad weather.
Such a portable and self-contained farming solution would be most appealing in dry coastal regions that get plenty of sunshine, such as the Arabian Gulf, North Africa and Australia.
“I wouldn’t say it’s a silly idea,” Voutchkov says. “But it’s an idea that can’t get a practical implementation in the short term. In the long term, I do believe it’s a visionary idea.”
Floating farms may come with a large price tag, Moustafa admits. Still, expanding agriculture should “be more of a priority than building costly football stadiums or indoor ski parks in the desert,” he argues.
Whether or not farming will ever take to the seas, new desalination technologies will transform the way society quenches its thirst. More than 300 million people rely on desalination for at least some of their daily water, and that number will only grow as needs rise and new materials and techniques improve the process.
“Desalination can sometimes get a rap for being energy intensive,” Dave says. “But the immediate benefits of having access to water that would not otherwise be there are so large that desalination is a technology that we will be seeing for a long time into the future.”
The scorching temperatures mean 2016 is all but certain to be the hottest year ever recorded, beating the previous hottest year in 2015, which itself beat 2014. This run of three record years is also unprecedented and, without climate change, would be a one in a million chance. Scaife says: “Including this year so far, 16 of the 17 warmest years on record have been since 2000 – it’s a shocking statistic.”
Shattered records show climate change is an emergency today, scientists warn
Unprecedented temperature levels mean more heatwaves, flooding, wildfires and hurricanes as experts say global warming is here and affecting us now

New Gecko-Inspired Adhesive
Flexible patches of silicone that stick to skin and conduct electricity could serve as the basis for a new, reusable electrode for medical applications.
For years, researchers have recreated the microscopic hair-like pillars on gecko feet that, through atomic forces known as van der Waals’ interactions, allow the animals to scurry up walls and across ceilings. Such gecko-inspired adhesives could have a variety of applications, including medical bandages, but materials scientist Seokwoo Jeon at the Korea Advanced Institute of Science and Technology (KAIST) and colleagues wanted to apply these materials to create a novel wearable electrode.

Flash back one year ago. Six very happy NYU students won the grand prize of $75,000 in the Entrepreneurs Challenge, held by Stern’s Berkley Center for Entrepreneurship and Innovation, for Ephemeral, a clever temporary tattoo ink system.
Traditional tattoos last forever because the ink is made of very large molecules. Macrophages, the cells your immune system uses to get rid of stuff like bacteria, just can’t break down the huge dye molecules.
Ephemeral uses a different approach. Lam, another of Ephemeral’s co-founders and the company’s Senior R&D Researcher, said that each dye molecule in their ink is small but it’s encased in a special capsule.
“The reason it’s encapsulated is so that it stays in the skin, so the macrophages can’t eat it up,” Lam said.
These capsules protect the ink from your immune system, but they also can easily be dissolved by a removal solution that Ephemeral has developed. If you decided you no longer want an Ephemeral tattoo, an artist would simply retrace the design with a tattoo gun loaded with the removal solution.
The Ephemeral team included Chemical and Biomolecular Engineering students: Jason Candreva (Ph.D.), Brennal Pierre (Ph.D.), Vandan Shah (Ph.D.), Anthony Lam (B.S.), and Seung Shin (B.S.) and Joshua Sakhai (B.S.), a Stern student majoring in Math, Finance, and Computer Science.

A Mercury Transit Music Video from Solar Dynamics Observatory
Video Credit: NASA‘s Goddard Space Flight Center, Genna Duberstein; Music: Encompass by Mark PetrieExplanation: What’s that small black dot moving across the Sun? Mercury. Possibly the clearest view of Mercury crossing in front of the Sun earlier this week was from Earth orbit. The Solar Dynamics Observatory obtained an uninterrupted vista recording it not only in optical light but also in bands of ultraviolet light. Featured here is a composite movie of the crossing set to music. Although the event might prove successful scientifically for better determining components of Mercury’ ultra-thin atmosphere, the event surely proved successful culturally by involving people throughout the world in observing a rare astronomical phenomenon. Many spectacular images of this Mercury transit from around (and above) the globe are being proudly displayed.
