NASA launched the Juno mission to Jupiter on August 5, 2011. After a five-year flight, the spacecraft entered orbit on July 4, 2016.
Jupiter is the largest planet in the Solar System, with an equatorial diameter of 142,984 kilometers. It is so large that it could contain all of the other planets within its volume. Since Jupiter rotates in a mere 9.925 hours, its equatorial diameter is more than 9275 kilometers greater than the distance between its poles.
Anyone who’s owned a vintage car can tell you—and boy, will they tell you—how much time, money, and maintenance is required to keep their baby running. And don’t forget the gasoline, garage oil puddles, or tailpipe pollution involved.
A California startup may have the answer: A plug-and-play innovative motor to convert that finicky old gas-guzzler into an electric car. Eric Hutchison and Brock Winberg first gained attention by rescuing a moldering, V-8-powered 1978 Ferrari 308—you may know it as the model that “Magnum: P.I.” drove on TV—and transforming it into an electric marvel. Now, the co-founders of Electric GT have developed a DIY, electric “crate motor” that will let traditional gearheads or EV fans do the same.
“A lot of guys go out for a weekend in a classic car that’s 40 or 50 years old, but they get a ride home with AAA; it ends up being a one-way trip,” Hutchison says. “Here, you’re taking out 95 percent of the maintenance, which is the biggest problem with classic cars. So this is for enthusiasts who love their cars, but want a fun, reliable car that’s good for 100 or 125 miles on a weekend drive.”
Molten salt storage in concentrated solar power plants could meet the electricity-on-demand role of coal and gas, allowing more old, fossil fuel plants to retire.

3D printers are revolutionizing manufacturing by allowing users to create any physical shape they can imagine on-demand. However, most commercial printers are only able to build objects from a single material at a time and inkjet printers that are capable of multimaterial printing are constrained by the physics of droplet formation. Extrusion-based 3D printing allows a broad palette of materials to be printed, but the process is extremely slow. For example, it would take roughly 10 days to build a 3D object roughly one liter in volume at the resolution of a human hair and print speed of 10 cm/s using a single-nozzle, single-material printhead. To build the same object in less than 1 day, one would need to implement a printhead with 16 nozzles printing simultaneously!
Now, a new technique called multimaterial multinozzle 3D (MM3D) printing developed at Harvard’s Wyss Institute for Biologically Inspired Engineering and John A. Paulson School of Engineering and Applied Sciences (SEAS) uses high-speed pressure valves to achieve rapid, continuous, and seamless switching between up to eight different printing materials, enabling the creation of complex shapes in a fraction of the time currently required using printheads that range from a single nozzle to large multinozzle arrays. These 3D printheads themselves are manufactured using 3D printing, enabling their rapid customization and facilitating adoption by others in the fabrication community. Each nozzle is capable of switching materials at up to 50 times per second, which is faster than the eye can see, or about as fast as a hummingbird beats its wings. The research is reported in Nature.
“When printing an object using a conventional extrusion-based 3D printer, the time required to print it scales cubically with the length of the object, because the printing nozzle has to move in three dimensions rather than just one,” said co-first author Mark Skylar-Scott, Ph.D., a Research Associate at the Wyss Institute. “MM3D’s combination of multinozzle arrays with the ability to switch between multiple inks rapidly effectively eliminates the time lost to switching printheads and helps get the scaling law down from cubic to linear, so you can print multimaterial, periodic 3D objects much more quickly.”
Scientists at the University of Birmingham have unravelled the genetic mechanisms behind tiny waterfleas’ ability to adapt to increased levels of phosphorus pollution in lakes.
By mapping networks of genes to the physiological responses of ancient and modern waterfleas (Daphnia), the researchers, based in the University’s School of Biosciences, were able to show that a cluster of over 800 genes, many of them involved in metabolic processes, evolved to become “plastic”, or flexible.
This allows the modern Daphnia to adjust its gene expression according to the amount of phosphorus present in the environment. This is particularly fascinating as their 700-year-old ancestors were incapable of such a plastic response.
While quantum computers won’t be found on your office desk anytime soon, these blueprints could, over time, make quantum computing much more accessible Soon, with companies like D-Wave continually improving quantum computing through user input, advancements could come sooner than expected.
“Federal health officials say the numbers of antibiotic resistant bacteria much worse than previously thought the centers for disease control warned in twenty thirteen that poor stewardship of antibiotics was causing more infections that couldn’t be treated a new report today says those cases have double billions are affected and tens of thousands dying in the U.

Ebola is now officially preventable and treatable. Today the World Health Organization (WHO) prequalified an Ebola vaccine for the first time in the history of the world. The Ervebo vaccine is now recommended by the WHO Strategic Advisory Group of Experts (SAGE) as a key tool in treating Ebola, as it’s been officially shown to be effective in protecting humans from the Ebola Zaire virus.
