Megafloods on Mars. 😃


Swept Away

The end result — which the scientists identified using data from NASA’s Curiosity rover — is that the floods shaped the surface of Mars into 30-foot-tall ripples of rock and dust. The water itself is long gone — but the scientists speculate that the floods means the planet may have been inhabitable at the time.

“Early Mars was an extremely active planet from a geological point of view,” study coauthor Alberto Fairén, an astrobiologist visiting Cornell, said in the release. “The planet had the conditions needed to support the presence of liquid water on the surface — and on Earth, where there’s water, there’s life.”

Jupiter and Saturn will be aligned this December, it seems. Something not seen since the middle ages. 🙂


Jupiter and Saturn are about to line up in a way not seen since the Middle Ages, astronomers say.

When the sun sets on 21 December – the winter solstice – people looking up to the sky will see Jupiter and Saturn closer than anyone alive has ever seen them before.

It will be the first time that such a sight has been seen for 800 years.

Werner Herzog criticizes Musk and SpaceX prepares to break a rocket reusability record. What’s next for Crew Dragon? It’s Musk Reads: SpaceX Edition #221.

Back in 2013, Elon Musk released the “Hyperloop Alpha” PDF outlining his vision for a space-age styled pod that would speed 700 mph through a vacuum tube. More than seven years later, one company is actually coming close to making it a reality — and we have an exclusive interview with its co-founder and first passenger. You’ll only read it in Musk Reads+.

Elon Musk made new comments about the Tesla Semi program, Tesla’s upcoming electric semi truck, and said that the vehicle will eventually have up to 1,000 km (621 miles) of range.

This new range is going to be achieved, thanks to Tesla’s new in-house battery cells and battery pack technology.

When launching Tesla Semi in 2017, the automaker said that the production versions of Tesla Semi, which is a class 8 truck with a 80,000-lb capacity, will have 300-mile and 500-mile range options for $150,000 and $180,000, respectively.

Another great advantage is the ability to incorporate AI at early stages of image acquisition. Among other things, this enables us to reduce the amount of radiation needed to acquire a high-resolution CT or shorten the duration needed for an MRI scan. And this leads to patient welfare improvements as well as healthcare cost reductions.

AI applications

In recent years there has been tremendous work in this field mainly focusing on cardiovascular, ophthalmology, neurology, and cancer detection.

Consumer drones have over the years struggled with an image of being no more than expensive and delicate toys. But applications in industrial, military and enterprise scenarios have shown that there is indeed a market for unmanned aerial vehicles, and today, a startup that makes drones for some of those latter purposes is announcing a large round of funding and a partnership that provides a picture of how the drone industry will look in years to come.

Percepto, which makes drones — both the hardware and software — to monitor and analyze industrial sites and other physical work areas largely unattended by people, has raised $45 million in a Series B round of funding.

Alongside this, it is now working with Boston Dynamics and has integrated its Spot robots with Percepto’s Sparrow drones, with the aim being better infrastructure assessments, and potentially more as Spot’s agility improves.

This is a story about math educator Mark Saul, and his Math on The Border program for migrant children. Mark and his team are trying to work with these children, and to encourage them. Mark is not only one of the best math educators in the world, he is also an amazing human being.


Having an opportunity to use one’s brain is a basic human need, says Saul. Back at the Templeton Foundation, he studied under-exploited human capital and the boundless human potential. Despite their difficult past and uncertain future, migrant children are eager to build their math skills. Resourceful and resilient in the face of failure, they reshuffle the pieces and try again. They work in groups and make new friends along the way. Many of them are highly gifted – Saul can attest to that. It doesn’t take him long to see what these children, abandoned by life, are capable of with just a little encouragement. And he can tell from the looks on their faces how delighted they are at having their abilities recognized and valued.
