Metro Skyway, a subsidiary of the Tel Aviv-based Urban Aeronautics, just introduced its plans to build a four-person, hydrogen-powered “flying car” that it hopes will be buzzing above skyscrapers by 2022.

New window screens with pollutant-trapping nanofibers may allow residents of smog-choked cities to breathe easier. The fibers are made of nitrogen-containing polymers and are sprayed onto screens in a technique called blow-spinning, in which a stream of air stretches out droplets of polymer solution in midspray to form an extremely thin layer of nanofibers.
Swarms of cheap “CubeSats” are currently being planned by companies who want to bring wireless internet access to every corner of the globe. But there’s nothing to stop these sprawling “megaconstellations”, which would include thousands of spacecraft, from colliding with other satellites and unleashing hazardous space debris in low Earth orbit.
A squadron of miniature spacecraft has set off on an expedition to a little-known zone of Earth’s atmosphere. Riding an Atlas V rocket, they took off from Cape Canaveral in Florida at 1111 local time today, headed for the International Space Station.
Some scientists are thinking about what human space travelers will look like in the future. They might be extra-small and radiation-proof.
Forty years ago, Canadian physicist Bill Unruh made a surprising prediction regarding quantum field theory. Known as the Unruh effect, his theory predicted that an accelerating observer would be bathed in blackbody radiation, whereas an inertial observer would be exposed to none.

There’s a particular type of lizard that changes the color of its spots as it ages — and researchers have just discovered the mathematical rules that govern this peculiar metamorphosis.
New research from Emory University School of Medicine shows that a chemical in the mucus of South Indian frogs is capable of killing certain strains of the influenza virus.
Komodo dragon blood contains an important compound which scientists think could offer a new treatment for infected wounds.
The reptile’s saliva harbours many different types of bacteria, which somehow do not affect the dragon.
For a long time, medieval medicine has been dismissed as irrelevant. This time period is popularly referred to as the “Dark Ages,” which erroneously suggests that it was unenlightened by science or reason. However, some medievalists and scientists are now looking back to history for clues to inform the search for new antibiotics.
Egyptian archaeologists have unearthed several mummies, colourful wooden sarcophagi and more than 1,000 funerary statues in a 3,500-year-old tomb near the city of Luxor, hailing an “important discovery”.
One of the world’s first nature pictures was a wild cow. A team of archaeologists found the earliest known depiction of an animal on a slab of rock in Southwestern France. According to a research paper published in the journal, Quaternary International, in January, the artifact was created by the Aurignacians, the first humans to migrate from Africa to Western Eurasia between 40,000 and 50,000 years ago.
Studies of bones from Ice Age megafaunal animals across Eurasia and the Americas have revealed that major increases in environmental moisture occurred just before many species suddenly became extinct around 11-15,000 years ago. The persistent moisture resulting from melting permafrost and glaciers caused widespread glacial-age grasslands to be rapidly replaced by peatlands and bogs, fragmenting populations of large herbivore grazers.
Four hundred and thirty million years ago, long before the evolution of barracudas or sharks, a different kind of predator stalked the primordial seas. The original sea monsters were eurypterids—better known as sea scorpions.
The Red Planet lacks a source of carbon dioxide that could transform its thin, cold atmosphere into something resembling conditions on Earth.
Massive landslides, similar to those found on Earth, are occurring on the asteroid Ceres. That’s according to a new study led by the Georgia Institute of Technology, adding to the growing evidence that Ceres retains a significant amount of water ice.
Many physicists delving deep into the heart of matter in recent decades have been lured to the more exotic and unfamiliar subatomic particles: mesons, neutrinos and the famous Higgs boson — not the humble proton.
