Exploring Ice-Ocean Interactions on Alien Moons

Posted by in categories: alien life, robotics/AI

“There’s a connection between the shape of the ice shell and the temperature in the ocean,” said Dr. Britney Schmidt. “This is a new way to get more insight from ice shell measurements that we hope to be able to get for Europa and other worlds.”

While Earth remains the only known world with bodies of liquid water on its surface, there are a myriad of worlds within our own solar system that have liquid water oceans beneath thick surfaces of ice. But what is the temperature of those interior oceans, and could the thickness of its ice shell determine it? This is what a recent study published in Journal of Geophysical Research Planets hopes to address as a team of researchers led by Cornell University investigated how a process called “ice pumping” could determine the temperature of the interior ocean underneath thick icy shells, also known as ice-ocean interaction. This study holds the potential to help researchers better understand the conditions for finding life beyond Earth with a focus on Jupiter’s moon, Europa, and Saturn’s moon, Enceladus.

“If we can measure the thickness variation across these ice shells, then we’re able to get temperature constraints on the oceans, which there’s really no other way yet to do without drilling into them,” said Dr. Britney Schmidt, who is an Associate Professor of Astronomy & Earth and Atmospheric Sciences at Cornell University and a co-author on the study. “This gives us another tool for trying to figure out how these oceans work. And the big question is, are things living there, or could they?”

Doroni unveils production-intent H1-X eVTOL, offering personal air travel up to 120 mph [Video]

Posted by in categories: sustainability, transportation

Young urban air mobility (UAM) developer Doroni Aerospace is stepping out of the shadows and into the eVTOL startup with the official reveal of its flagship aircraft – the H1-X. The two-seat eVTOL was showcased during a livestream event today and is damn close to being market-ready, touting some impressive specs.

Doroni Aerospace was founded in 2016 by Doron Merdinger – a lifelong entrepreneur with 25 years of design, manufacturing, and firm management expertise.

To bring his dreams of sustainable aviation transportation to life, Merdinger assembled a team of engineers and technicians working together to democratize flight in a growing eVTOL segment.

2024 U.S. Electric Cars Compared By Price Per Mile Of EPA Range

Posted by in categories: sustainability, transportation

Electric vehicles’ price and driving range are probably the two most important factors for most buyers. In today’s post, we will look at the mix of the two parameters—the price per mile of the EPA Combined range.

That may sound complex, but it’s merely a metric that indicates the best value proposition overall, and something that gives us an idea of the “cost” of range. By checking this metric, we can also see whether there is progress over time compared to earlier reports: see February 2022, February 2021 or April 2020. As it turns out, progress is happening on this front, and the cost of the driving range is going down.

Before we jump into details, let’s just explain the basics. There are more than 300 individual EV configurations on sale, including different battery sizes, ranges, powertrain setups, and wheels—all of which directly affect the price and range. We collected numbers for about 300 configurations, that are currently available for order or reservation, some upcoming models, and a few that have been discontinued but may still be found on dealer lots as reference points.

The business behind Tesla opening its Supercharger network: selling ‘memberships’

Posted by in categories: business, transportation

While I believe Tesla’s move to open its Supercharger network to other automakers is ultimately going to have a great impact on EV adoption, it is also a smart business move from Tesla.

Here’s the business behind Tesla opening its Supercharger network.

Tesla, to no fault of its own, has been using its Supercharger network as a moat in the North American EV market.

‘This is my calling’: building point-of-care diagnostic tools to fight tuberculosis

Posted by in categories: biotech/medical, chemistry

Inside her small office, with a window overlooking the iconic Kerckhoff Hall student centre at University of California, Los Angeles (UCLA), chemical biologist Mireille Kamariza is pursuing her big dream. Since 2015, she has steadily worked to stop transmission of deadly tuberculosis (TB) superbugs, which in 2022 infected more than 10 million people and killed more than one million.

As a PhD student working with Nobel laureate Carolyn Bertozzi, now a chemist at Stanford University in California, she developed a fluorescent diagnostic test that could be used for quick detection of TB, especially in resource-poor settings. In 2019, alongside Bertozzi, Kamariza founded the biotech start-up company OliLux Biosciences, based in Los Angeles, to develop reliable tools for detecting TB that are tailored to the complex needs of poorer countries. Nature sat down with Kamariza to talk about her progress in testing these diagnostic tools for use in the real world, and the uphill battle in fighting the spread of TB.

Black Holes Were Such an Extreme Concept, Even Einstein Had His Doubts

Posted by in categories: cosmology, physics

Einstein’s theory of relativity paved the way for black holes’ discovery, but the concept behind their existence was so bizarre that even the scientific visionary was not convinced.

More than a century ago, Albert Einstein stunned the world when he explained the universe through his theory of general relativity. The theory not only described the relationship between space, time, gravity and matter, it opened the door to the theoretical possibility of a particularly mind-boggling phenomenon that would eventually be called black holes.

Aptera’s latest update teases its solar EV app, battery tech, and delivery timelines [Video]

Posted by in category: transportation

Solar EV startup Aptera Motors continued its welcomed level of public transparency today, posting another progress update video for February, offering some juicy details. Aptera co-founder Steve Fambro walks you through the first glimpse at the upcoming Aptera app, which promises several cool features; plus, we get a look at some Solar EV battery packs and some hints at how safe the production vehicle will be. You can learn more in the full video below.

There is a multitude of reasons why Aptera Motors is different from the other OEMs out there. The most obvious is that the California-based startup is really the only company left trying to bring Solar EVs to full-scale production, and it is closer than ever, following a successful $34 million crowdfunding program.

Additionally, Aptera constantly keeps its growing fanbase as well as EV enthusiasts in the know of its progress in developing its solar EVs, posting monthly updates to YouTube. There is also plenty of news coming out of Aptera HQ in between those monthly videos. For example, Aptera offered the public a look at its production-intent build process in mid-February.
