You’d like to get into the drone sensation, but you don’t want to break the bank to do it. Don’t worry: there are plenty of options in the $100–300 range that include everything you need.

Before we continue: the term “drone” is a misnomer, since it technically describes something that can navigate on its own, not simply a remote control device. But then again, some of the more advanced models available—even a few on this list!—can indeed fly on their own, returning to their operator if a signal is lost, performing some pre-programmed tricks, or even avoid obstacles. So perhaps a persnickety terminology gripe is unwarranted, but we always want to ensure our readers are well informed and end up with a product that meets their expectations.

We’ve selected the best all-around drone for beginners, a cheap and durable one for kids, a drone that folds up for easy travel, one that’s ideal if you want to get into the exciting drone racing scene, and an upgrade model if you’re ready to spend a little more for advanced features.

Speaking in a September 7th interview with French newspaper Courrier International, Dr. Francis Rocard – director of French space agency CNES’ solar system exploration program – had little good to say about SpaceX and CEO Elon Musk’s long-term ambitions in space, going so far as to question the CEO’s driving ethics and label the company’s next-generation rocket and propulsion system “science-fiction”.

There’s something out there that physicists have never seen before, and it’s coming up from the bottom of the Earth. Scientists think it’s a brand-new particle.

Just how valuable is that stretch of space between Earth and the moon’s orbit? Might this celestial real estate become hot property as an extension of military arenas in low Earth orbit, medium Earth orbit, and geosynchronous orbit?

Given forecasts of 21st-century activity on and around the moon by both private and government entities, could this be an economic area of development that needs protection in sthe years and decades to come? [In Photos: President Donald Trump and NASA].

A recent open-access mouse study published by Xi’an Institute of Tissue Engineering and Regenerative Medicine scientists in the journal Bone Research describes how the ALPL gene affects bone aging and suggests that metformin might constitute a viable therapeutic option to prevent it [1].

Study abstract

Mutations in the liver/bone/kidney alkaline phosphatase (Alpl) gene cause hypophosphatasia (HPP) and early-onset bone dysplasia, suggesting that this gene is a key factor in human bone development. However, how and where Alpl acts in bone ageing is largely unknown. Here, we determined that ablation of Alpl induces prototypical premature bone ageing characteristics, including bone mass loss and marrow fat gain coupled with elevated expression of p16INK4A (p16) and p53 due to senescence and impaired differentiation in mesenchymal stem cells (MSCs). Mechanistically, Alpl deficiency in MSCs enhances ATP release and reduces ATP hydrolysis. Then, the excessive extracellular ATP is, in turn, internalized by MSCs and causes an elevation in the intracellular ATP level, which consequently inactivates the AMPKα pathway and contributes to the cell fate switch of MSCs.

The alliance urges the European Commission to implement an AI strategy for the EU as a whole along the lines of the US National AI Research and Development Plan that was released in late 2016, and China’s Next Generation AI Development Plan that was issued the following year.

More than 2,000 researchers join forces to urge EU to help continent build ‘Google-style’ infrastructure as counterweight to the two leading AI players.

Astronomers found something not predicted by current theory when they took a closer look at the emissions from a neutron star with a very strong magnetic field.

British set designer Es Devlin has been chosen to create the UK Pavilion at the Dubai Expo 2020, with a performative structure that will use artificial intelligence to write poems.

Called the Poem Pavilion, the structure will feature an illuminated “message to space” made up of numerous AI-generated poems, which the Expo’s anticipated 25 million visitors will be invited to contribute to.

The 20-metre-high, cone-shaped pavilion will be made up of rows of protruding slats that extend outwards from one central point to form a circular facade. Poems lit up in LEDs will scroll across the facade.

Microsoft and Shell are teaming up to try and make pumping gas safer by developing AI capable of alerting employees when an idiot smokes at the pump.
