Looking deeper into graphene using rainbow scattering
Posted by Genevieve Klien in categories: materials, particle physics
Graphene is a two-dimensional wonder material that has been suggested for a wide range of applications in energy, technology, construction, and more since it was first isolated from graphite in 2004.
This single layer of carbon atoms is tough yet flexible, light but with high resistance, with graphene calculated to be 200 times more resistant than steel and five times lighter than aluminum.
Graphene may sound perfect, but it very literally is not. Isolated samples of this 2D allotrope aren’t perfectly flat, with its surface rippled. Graphene can also feature structural defects that can, in some cases, be deleterious to its function and, in other instances, can be essential to its chosen application. That means that the controlled implementation of defects could enable fine-tuning of the desired properties of two-dimensional crystals of graphene.

SpaceX Falcon Heavy to launch world’s largest private communications satellite on July 26
Posted by Genevieve Klien in categories: internet, satellites
SpaceX is poised to launch the world’s largest commercial communications satellite.
On Wednesday (July 26), a SpaceX Falcon Heavy rocket will launch Maxar Technologies’ largest ever satellite, the Jupiter 3. The communications platform will join others in the Hughes Jupiter satellite fleet already in orbit, which provides broadband internet services to North and South America. According to a Hughes statement, the satellite will be the world’s largest commercial communications satellite once it’s fully deployed.

Denver Offers to Train Interpreters for Free to Deal With Influx of Foreigners
Posted by Brent Ellman in category: futurism
In Denver, people can now turn their bilingual skills into cash — and perhaps a promising future — thanks to a first-of-its-kind program being rolled out by the Denver Office of Immigrant & Refugee Affairs in which residents will be able to get free interpreter training and a chance at contract work with the city.
DOIRA officials are looking for anyone who is proficient in English and one of more than a dozen listed languages, including Vietnamese, Amharic, Cantonese, Mandarin, Arabic, Russian, French, Burmese, Karen, Farsi, Somali, Nepali, Korean, Urdu, Haitian Creole, Khmer Armenian and Swahili, and are open to those who speak additional dialects, as well.
With the city welcoming more and more foreign-born residents — including refugees looking for help with local services — the Office of Immigrant & Refugee Affairs is in need of interpreters. It plans to start training polyglots next month, with classes beginning on August 21 and running for about three weeks.

The World’s First Flying Car Approved in US: Here’s What It Looks Like
Posted by Dan Breeden in category: transportation
In two years, the world’s first flying car will no longer be a science-fiction concept. The Federal Aviation Administration gave the Alef Aeronautics “Model A” car a Special Airworthiness Certification in June, approving the vehicle for road and air tests, the New York Post reported.

What Happens When Scientists Put a Human Intelligence Gene Into a Monkey?
Posted by Omuterema Akhahenda in categories: biotech/medical, evolution, genetics, neuroscience
Scientists adding a human intelligence gene into monkeys — it’s the kind of thing you’d see in a movie like Rise of the Planet of the Apes. But Chinese researchers have done just that, improving the short-term memories of the monkeys in a study published in March 2019 in the Chinese journal National Science Review. While some experts downplayed the effects as minor, concerns linger over where the research may lead.
The goal of the work, led by geneticist Bing Su of Kunming Institute of Zoology, was to investigate how a gene linked to brain size, MCPH1, might contribute to the evolution of the organ in humans. All primates have some variation of this gene. However, compared with other primates, our brains are larger, more advanced and slower to develop; the researchers wondered whether differences that evolved in the human version of MCPH1 might explain our more complex brains.
