It’s a sad day. The observatory has not only been used to observe radio wave signals in deep space. It’s also become an iconic landmark over the decades after being featured in countless films and TV shows including the 1995 James Bond blockbuster “GoldenEye.”
The observatory has also made significant contributions to the Search for Extraterrestrial Intelligence (SETI), spotting mysterious radio signals emanating from distant corners of the universe.
“This decision is not an easy one for NSF to make, but safety of people is our number one priority,” Sean Jones, the assistant director for the mathematical and physical sciences directorate at NSF, told reporters today over a conference call, as quoted by The Verge.
The automotive industry is knee deep in the vast transition to electric, but one place where gas is still going strong is out on the water. Seattle startup Zin Boats wants to start what you might call a sea change by showing, as Tesla did with cars, that an electric boat can be not just better for the planet, but better in almost every other way as well.
With a minimalist design like a silver bullet, built almost entirely from carbon fiber, the 20-foot Z2R is less than half the weight of comparable craft, letting it take off like a shot and handle easily, while also traveling a hundred miles on a charge — and you can fill the “tank” for about five bucks in an hour or so.
Waiting for the other shoe to drop? Well, it ain’t cheap. But then, few boats are.
This simple laser demonstration is actually a great crash course on how these anti-drone weapons work.
At first glance, this video is just a simple promotional video for Rafael’s Drone Dome, an anti-drone laser weapon. But at just two minutes long, it does a really excellent job at explaining what how a laser weapon actually takes down a drone.

Desertification is a type of land degradation in dry-lands in which biological productivity is lost due to natural processes, or induced by human activities, whereby fertile areas become increasingly arid, and may be caused by a variety of factors, such as climate change and over exploitation of soil.
ADIFO stands for All-DIrectional Flying Object. This miniature prototype could someday turn into a supersonic vehicle capable of suborbital flight as well as flying upside down!
This is the episode for anyone who’s interested in learning more about our grand spiral neighbor, the Andromeda Galaxy. Join my guest Lowell Observatory, astronomer Phil Massey as we discuss how our beguiling behemoth of a neighbor helped shape contemporary astronomy.
First cataloged by Al Sufi as a mere optical smudge high in the winter sky, the Andromeda Galaxy has lately been a cornerstone of everything we know about contemporary astronomy and the cosmos as a whole. Join Lowell Observatory astronomer Philip Massey as he outlines how this grand spiral neighbor changed what we know about cosmology. And if you happen to be in the Northern hemisphere, by the end of the episode, you may be ready to try and spot the galaxy with just your naked eyes.
VTOL (vertical take-off and landing) drones are quite versatile, as they combine the vertical flight of a helicopter with the fast and efficient forward flight of a fixed-wing airplane. This one features an extended range, thanks to a fuel cell power system.
The experimental aircraft was developed by a team at the Netherlands’ Delft University of Technology (TU Delft), working with colleagues from the Royal Netherlands Navy and the Netherlands Coastguard. It has a 3-meter wingspan (9.8 ft), weighs 13 kg (29 lb), and features 12 motor/propeller units distributed on its two wings. Even if several of the motors fail, it can reportedly still fly and land successfully.
The drone is also a “tail-sitter”-type VTOL. This means that when taking off and landing, its body is angled upwards, allowing the propellers to work more like a helicopter’s rotor blades. For going into forward flight, the thrust is electronically redistributed between the 12 motors, causing the aircraft to level out into a horizontal orientation.
This may be good news for those who have damaged joints due to sports or old age.

Human knees are notoriously vulnerable to injury or wearing out with age, often culminating in the need for surgery. Now researchers have created new hybrid bioinks that can be used to 3D print structures to replace damaged cartilage in the knee.
The meniscus is the rubbery cartilage that forms a C-shaped cushion in your knee, preventing the bones of your upper and lower leg from rubbing against each other. This stuff is susceptible to damage from sports injuries, but can also wear out with age – and if it gets particularly bad, sometimes the only thing left to do is surgically remove some of the damaged meniscus.
If there’s one major thing that’s holding back an electric revolution in the aviation world, it’s energy storage. But there are a ton of very clever people banging away at the problem of how to increase the energy density of batteries, and another growing faction working to make long-range, fast-fueling hydrogen-fuel-cell powertrains the standard for future flight.
Either way, it’s going to happen in the coming decades, and one new company out of Minneapolis is turning its attention to the other critical element of the propulsion system. H3X Technologies is bursting out of the gate with an integrated electric motor design it says can deliver the same sustained power as some of the best motors on the market at a third or less of the total weight.
Weight, of course, is a big deal in aviation – and that goes double for electric aircraft. Every pound carried skyward represents a pound less payload you can carry, a reduction in the range you’ll get from your battery or hydrogen tank, and ultimately a loss of money for the owner.
