Tesla Semi electric truck to have up to 621 miles of range, says Elon Musk

Posted by in categories: Elon Musk, sustainability, transportation

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.

AI and the transformation of the medical world

Posted by in categories: biotech/medical, robotics/AI

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.

Industrial drone maker Percepto raises $45M and integrates with Boston Dynamics’ Spot

Posted by in categories: drones, military, robotics/AI

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.

How A Leading Educator For Gifted Students Discovers Untapped Potential Of Migrant Children Through Math

Posted by in categories: mathematics, neuroscience

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.

Sestrin makes fruit flies live longer

Posted by in categories: biotech/medical, food, life extension

10% longer.

Reduced food intake, known as dietary restriction, leads to a longer lifespan in many animals and can improve health in humans. However, the molecular mechanisms underlying the positive effects of dietary restriction are still unclear. Researchers from the Max Planck Institute for Biology of Aging have now found one possible explanation in fruit flies: they identified a protein named Sestrin that mediates the beneficial effects of dietary restriction. By increasing the amount of Sestrin in flies, researchers were able to extend their lifespan and at the same time these flies were protected against the lifespan-shortening effects of a protein-rich diet. The researchers could further show that Sestrin plays a key role in stem cells in the fly gut thereby improving the health of the fly.

The health benefits of have long been known. Recently, it has become clear that restriction of certain food components, especially proteins and their individual building blocks, the , is more important for the organism’s response to dietary restriction than general calorie reduction. On the , one particular well-known signaling pathway, named TOR pathway, is important for longevity.

Quantum X-ray microscope “ghost images” molecules using entanglement

Posted by in category: quantum physics

Engineers at Brookhaven National Laboratory have designed a strange new X-ray microscope that takes advantage of the spooky world of quantum physics to “ghost image” biomolecules in high resolution but at a lower radiation dose.

X-ray microscopes are useful tools for imaging samples in high resolution, but the radiation involved can damage sensitive samples such as viruses, bacteria and some cells. Reducing the radiation dose is one way around that problem, but unfortunately that also reduces the resolution of the image.

Now, the Brookhaven team has found a way to maintain higher resolution with a lower radiation dose – and all they had to do was tap into the quirks of quantum physics that boggled minds like Einstein’s.

Amateur astronomer Alberto Caballero finds possible source of Wow! signal

Posted by in category: alien life

Amateur astronomer and YouTuber Alberto Caballero, one of the founders of The Exoplanets Channel, has found a small amount of evidence for a source of the notorious Wow! signal. In his paper uploaded to the arXiv preprint server, Caballero describes searching the Gaia database for possible sun-like stars that might host an exoplanet capable of supporting intelligent life.

Back in 1977, astronomers working with the Big Ear Radio Telescope—at the time, situated in Delaware, Ohio—recorded a unique signal from somewhere in space. It was so strong and unusual that one of the workers on the team, Jerry Ehman, famously scrawled the word Wow! on the printout. Despite years of work and many man hours, no one has ever been able to trace the source of the signal or explain the strong, unique signal, which lasted for all of 72 seconds. Since that time, many people have suggested the only explanation for such a strong and unique signal is extraterrestrial .

In this new effort, Caballero reasoned that if the source was some other , it would likely be living on an exoplanet—and if that were the case, it would stand to reason that such a life form might be living on a planet similar to Earth—one circling its own sun-like star. Pursuing this logic, Caballero began searching the publicly available Gaia database for just such a star. The Gaia database has been assembled by a team working at the Gaia observatory run by the European Space Agency. Launched back in 2013, the project has worked steadily on assembling the best map of the night sky ever created. To date, the team has mapped approximately 1.3 billion .

A good COVID-19 vaccine is one that works for rich and poor alike

Posted by in categories: biotech/medical, health

And, of course, there is patriarchy. In some parts of the world, women have no control over their health. It is the men – fathers, husbands and uncles – who decide what treatment “their” women receive. Humanitarians have seen men refuse emergency caesareans for their wives. They have also seen them refuse vaccinations for women whose bodies they effectively control.

The Oxford-AstraZeneca vaccine has launched the world on a pro-poor route to fair global vaccination against COVID-19. This is wonderful news. Now we need to address the challenges of a pro-poor roll-out. A major part of this must involve all States getting behind the COVAX effort to ensure fair global access to COVID-19 vaccination tools. It is good to see the UK co-leading on this with others.
