Bizarre new dinosaur with giant claws discovered in China
It walked on two legs and may have looked like a feathered bear with giant claws. Meet Kayrasaurus changliensis—well, its almost complete skeleton, to be precise.
Could negative mass exist and be observed?
Unlike electric charge, as far as we know all mass is positive, and positive masses attract one another. Could negative mass exist, and if so, what would be the ramifications?
Zika virus assembles without protein segment long deemed essential
For years, scientists were certain that two factors were involved in the assembly of active, highly infectious Zika viruses in human cells: a specific viral protein in its entirety and a turncoat human enzyme that assured ...
Pigeons' proposed inner-ear compass runs into a noise problem
A pigeon turning its head might seem an unlikely electricity generator. Yet one proposed explanation for the bird's magnetic sense depends on exactly that: Turning through Earth's magnetic field would produce tiny electrical ...
Light beam 'swims' upstream through a quantum fluid by violating Newton's third law
Just as a leaf drifts along with a stream, objects in other moving fluids normally drift along with the flow. That is, unless they exert energy to move against it. Although it may be less intuitive, light waves or photons ...
What billiard balls reveal about computers and the limits of prediction
When is a billiard ball not a billiard ball? When mathematicians get involved and view a popular game as a model computer.
Astronomers detect radio signals coming from an exoplanet for the first time
Exoplanets are exotic worlds orbiting distant stars far beyond our solar system. Ever since the first ones were discovered in the 1990s, astronomers have turned their attention to these distant worlds to understand more about ...
Quantum protocol securely verifies a device's position using stations 2 km apart
Reliably verifying the location of a device connected to the internet or other networks is important for various real-world applications. For instance, it could be valuable for authorizing financial transactions, securing ...
Carbon nanotube foams reveal a new kind of mechanical memory
In their earliest years of development, computers used mechanical gears and levers to store information. Today, researchers are exploring whether a material itself can hold onto information, storing memory in how it bends ...
Antarctica's lost mountains may have helped early life flourish
Beneath the vast frozen wastes of Antarctica lie the remains of ancient mountains that have long since eroded. Even though they're no longer standing, they can still reveal a few lost secrets. New research published in Earth ...
