Nearly 100 tech companies have filed an amicus brief condemning U.S. President Donald Trump’s executive order concerning immigration.

The legal brief emphasizes what the companies believe to be the importance of immigrants in both the economy and society.

This from the brief:

Immigrants make many of the Nation’s greatest discoveries, and create some of the country’s most innovative and iconic companies. America has long recognized the importance of protecting ourselves against those who would do us harm. But it has done so while maintaining our fundamental commitment to welcoming immigrants—through increased background checks and other controls on people seeking to enter our country.

The brief cites the executive order as illegal, discriminatory, and ultimately damaging for U.S. companies. The complete list of opposing companies follows:

In an effort to purify water, researchers from the University at Buffalo are using carbon-dipped paper to make dirty water drinkable.

Those behind the research believe this new development could be a cheap and efficient way to address a global shortage in drinking water, specifically in developing areas.

“Using extremely low-cost materials, we have been able to create a system that makes near maximum use of the solar energy during evaporation,” says Qiaoqiang Gan, lead researcher. “At the same time, we are minimizing the amount of heat loss during this process.”

This from University at Buffalo:

The team built a small-scale solar still. The device, which they call a “solar vapor generator,” cleans or desalinates water by using the heat converted from sunlight. Here’s how it works: The sun evaporates the water. During this process, salt, bacteria, or other unwanted elements are left behind as the liquid moves into a gaseous state. The water vapor then cools and returns to a liquid state, where it is collected in a separate container without the salt or contaminants.

New technology that mimics the branches and leaves of a cottonwood tree can generate electricity with the help of the wind.

Researchers say that the new technology is not meant to be a replacement for wind turbines, but could offer an alternative electricity source for those looking for small, unobtrusive machines to transform wind into energy.

“The possible advantages here are aesthetics and its smaller scale, which may allow off-grid energy harvesting,” says Michael McCloskey, co-author of the study. “We set out to answer the question of whether you can get useful amounts of electrical power out of something that looks like a plant. The answer is ‘possibly,’ but the idea will require further development.”

On top of efficiency and affordability, consumers are also looking for alternative energy technologies to be aesthetically attractive, as demonstrated in Tesla’s solar roof.

According to McCloskey, cell phone towers in urban locations are sometimes camouflaged as trees to offer better aesthetic properties. The researchers believe that towers such as this, which already host fake leaves, could be greatly improved by implementing this technology to tap energy from the leaves and provide further functionality.

When a May 2016 crash killed the person operating a Tesla Model S driving in Autopilot mode, advocates of autonomous vehicles feared a slowdown in development of self-driving cars.

Instead the opposite has occurred. In August, Ford publicly committed to field self-driving cars by 2021. In September, Uber began picking up passengers with self-driving cars in Pittsburgh, albeit with safety drivers ready to take over.

October saw Tesla itself undeterred by the fatality. The company began producing cars it said had all the hardware needed for autonomous operation; the software will be written and added later. In December, days after Michigan established regulations for testing autonomous vehicles in December, General Motors started doing just that with self-driving Chevy Bolts. And just one day before the end of his term, U.S. Secretary of Transportation Anthony Foxx designated 10 research centers as official test sites for automated vehicle systems.

Three of the most significant developments in the industry happened earlier this month. The 2017 Consumer Electronics Show (CES) in Las Vegas and the North American International Auto Show in Detroit saw automakers new and old (and their suppliers) show off their plans and innovations in this arena. And the National Transportation Safety Board (NTSB) issued its report on the Tesla fatality. Together, they suggest a future filled with driverless cars that are both safer than today’s vehicles and radically different in appearance and comfort.

By using one of the world’s most powerful electron microscopes, a team of researchers from Lawrence Berkeley National Laboratory has successfully mapped the exact location and chemical type of 23,000 atoms in a nanoparticle made of iron and platinum. The team believes this work could reveal more information about material properties at the single-atom level, opening the doors to improving magnetic performance for next-generation hard drives.

“Our research is a big step in this direction. We can now take a snapshot that shows the positions of all the atoms in a nanoparticle at a specific point in its growth,” says Mary Scott, who conducted the research. “This will help us learn how nanoparticles grow atom by atom, and it sets the stage for a materials-design approach starting from the smallest building blocks.”

The ECS Toyota Young Investigator Fellowship kicked off in 2014, establishing a partnership between The Electrochemical Society and Toyota Research Institute of North America, aimed at funding young scholars pursuing innovative research in green energy technology.

The proposal deadline for the year’s fellowship is Jan. 31, 2017. Apply now!

While you put together your proposals, check out what Patrick Cappillino, one of the fellowship’s inaugural winners, says about his experience with the fellowship and the opportunities it presented.

The Electrochemical Society: Your proposed topic for the ECS Young Investigator Toyota Fellowship was “Mushroom-derived Natural Products as Flow Battery Electrolytes.” What inspired that work?

Patrick Cappillino: This research was inspired by a conversation with a colleague. I was relating the problem of redox instability in flow battery electrolytes. He told me his doctoral work had focused on an interesting molecule called Amavadin, produced by mushrooms, that was extremely stable and easy to make. The lightbulb really went off when we noticed that the starting material was the decomposition product of another flow battery electrolyte that has problems with instability.

The American Association for the Advancement of Science (AAAS) is calling on U.S. President Donald Trump to work with the world’s largest scientific organization to ensure the free flow of scientific talent from around the world.

The latest response from AAAS comes just after President Trump’s executive order limiting immigration and travel from seven countries in the Middle East. AAAS’s CEO, Rush Holt, issued a statement emphasizing the need to keep U.S. borders open to scientists and students from around the world.

“Scientific progress depends on openness, transparency, and the free flow of ideas. The United States has always attracted and benefited from international scientific talent because of these principles,” Holt said in the release. “We know that fostering safe and responsible conduct of research is essential for scientific advancement, national prosperity, and international security. Therefore, the detaining of students and scientists that have already been screened, processed, and approved to receive a visa to visit the United States is contrary to the spirit of science to pursue scholarly and professional interests. In order for science and the economy to prosper, students and scientists must be free to study and work with colleagues in other countries.”
