The dark, pitted rock, nicknamed 'Skull Hill', was discovered by NASA's Perseverance rover as its searched for signs of ancient life in the hills and rocky outcrops of Mars' barren Jezero Crater — a bowl-shaped depression that scientists suspect once held a huge ancient lake.
The rock stands out against the lighter-toned rock that surrounds it, leading scientists to suspect that it may not have formed there. Rather, it may have been transported on a Martian river or lake to its current position, billions of years ago. However, many questions still remain about the rock's origin and what it can tell us about the history of our cosmic neighbor.
The color, described by study participants as a "blue-green of unprecedented saturation," was made visible using a technique called "Oz" to stimulate a particular group of light receptors at the back of the participants' eyes.
The researchers say their method could be developed to restore color vision in those with color blindness, and that it could potentially provide enhanced digital viewing experiences in the future.

Pet cats, especially those with access to the great outdoors, sometimes bring their owners dead animals.

If you have an outdoor cat, you've probably been presented with "gifts" from your furry companion — usually in the form of dead birds and rodents. But have you ever wondered why they do this?
Your cat had to use a lot of energy to capture this prize, so eating it themselves would be the most sensible action from a survival perspective. But experts say there are several hypotheses for why they continue this bizarre behavior.
The new operating system is the first in the world that allows quantum computers with different kinds of qubits to function together in a single network.
Operating systems, like Microsoft Windows and Apple iOS, manage and control our computers' hardware and software. They enable users to interact with applications and allow different devices to connect with each other.
Most existing quantum computers are designed and built to carry out a specific function and use different kinds of quantum bits (qubits) to run their calculations. But now, a first-of-its-kind quantum operating system called QNodeOS has been developed to allow multiple quantum computers to connect and be controlled by a single central platform, regardless of the type of qubits they use.
Atlantic ocean currents regulate the climate, and they may be weakening, emerging research suggests.

The Atlantic Meridional Overturning Circulation, also known as the AMOC, is a large system of ocean currents that brings warm water from the tropics northwards and ferries colder water from north to south.
The system, which acts like an enormous watery conveyor belt, ensures that the oceans are continually mixed and that heat is distributed around the planet. However, a mysterious "blob" of water in the North Atlantic that has puzzled scientists for decades could be an ominous signal that these essential currents are slowing down. So, what would this mean for us?
Something for the weekend
If you're looking for something a little longer to read over the weekend, here are some of the best long reads, book excerpts and interviews published this week.
The video, shared by the Schmidt Ocean Institute, shows the two parasitic crustaceans called copepods trailing alongside the rattail fish, their long egg sacs flowing behind them like a pair of pigtails.
The footage was captured as part of an expedition to examine the seafloor and the diversity of weird and wonderful creatures that live down there.
