    Meet the Bobcat Nanowagon, the world’s smallest monster truck

    WASHINGTON, D.C. — The world’s smallest monster truck has a chemical curiosity under its hood.

    Made out of a mere five molecules, the Ohio Bobcat Nanowagon checks in at 3.5 nanometers long and 2.5 wide — about the width of a DNA strand. Even so, it was the heftiest contender in the first-ever nanocar race earlier this year. This pip-squeak vehicle took home the bronze, but perhaps more...

    Patience is one virtue scientists must embrace

    There’s a lot of waiting in science. Collecting and interpreting evidence demands skill and commitment, creativity and curiosity — and time. Though Saturn has been known since ancient times, Galileo first observed it with a telescope in 1610. He saw the rings, but didn’t identify them as such. Not until the 1650s did Dutch astronomer Christiaan Huygens report a flat ring around Saturn. The...

    Inquiries about the moon's twilight zone, and more reader feedback

    Locked up

    Simulations suggest that heat from an infant Earth, the sun and the moon could have vaporized the moon’s metals into a thick atmosphere, Lisa Grossman reported in “Metallic air may have swaddled moon” (SN: 8/5/17, p. 7). One way to test the idea would be to look for a ring of extra sodium in rocks around the moon’s twilight zone, where sodium snow would have accumulated. This zone...

    As Cassini’s tour of Saturn draws to a close, a look back at postcards from the probe

    Take a bow, Cassini. It’s been a marathon performance: 20 years in space, more than 200 orbits around Saturn, and hundreds of thousands of images of the giant planet, its splashy rings and its many moons. On September 15, the veteran spacecraft will use its last burst of fuel to plunge into the sixth planet from the sun. Scientists and space enthusiasts around the world will watch it go with...

    This ancient sea worm sported a crowd of ‘claws’ around its mouth

    View the video

    Predatory sea worms just aren’t as spiny as they used to be.

    These arrow worms, which make up the phylum Chaetognatha, snatch prey with Wolverine-like claws protruding from around their mouths. Researchers now report that a newly identified species of ancient arrow worm was especially heavily armed. Dubbed Capinatator praetermissus, the predator had about 50 curved...

    Seeing one picture at a time helps kids learn words from books

    We’re going through a comic book phase at my house. Since lucking into the comics stash at the library, my 4-year-old refuses any other literary offering. Try as I might to rekindle her love of Rosie Revere, my daughter shuns that scrappy little engineer for Superman every single night.

    I know that comic fans abound, but I’ll admit that I get a little lost reading the books. The multi-...

    New antennas are up to a hundredth the size of today’s devices

    Antennas just got a whole lot smaller.

    Tiny chips that communicate via radio waves are a tenth to a hundredth the length of current state-of-the-art compact antennas. At only a couple hundred micrometers across — comparable to the thickness of a piece of paper — these next-gen antennas can relay the same types of signals as those used by TVs, cell phones and radios, researchers report...

    These chip-sized spacecraft are the smallest space probes yet

    Spacecraft have gone bite-sized. On June 23, Breakthrough Starshot, an initiative to send spacecraft to another star system, launched half a dozen probes called Sprites to test how their electronics fare in outer space. Each Sprite, built on a single circuit board, is a prototype of the tiny spacecraft that Starshot scientists intend to send to Alpha Centauri, the trio of stars closest to the...

    Birth control research is moving beyond the pill

    Mention “the pill,” and only one kind of drug comes to mind. The claim that oral contraceptives have on that simple noun testifies to the pill’s singular effect in the United States. Introduced in 1960, the pill gave women reliable access to birth control for the first time. The opportunity to delay having children opened the door to higher education and professional careers for many women....
