New Images reveal what Neptune and Uranus really look like

New images reveal what Neptune and Uranus really look like

Neptune is fondly known for being a rich blue, and Uranus green—but a new study has revealed that the two ice giants are actually far closer in color than typically thought.

The correct shades of the planets have been confirmed with the help of research led by Professor Patrick Irwin from the University of Oxford, which has been published today in the Monthly Notices of the Royal Astronomical Society.

He and his team found that both worlds are in fact a similar shade of greenish blue, despite the c...

Yale researchers have identified a drug target that may alleviate joint degeneration associated with osteoarthritis, a debilitating condition that afflicts as many as 30 million people in the United States alone, which they report on Jan. 3 in the journal Nature.

Pain relievers and lifestyle changes, such as exercise and reduced excess weight, have long been the therapies most commonly used to treat the joint stiffness and pain caused by degenerative disease, but there is a pressing need for therapies that can prevent joint breakdown that occurs in osteoarthritis.

It is known that specialized proteins known as sodium channels found in cell membranes produce electrical impulses in “excitable” cells within muscles, the nervous system, and the heart.

And in p...

ICFO and Qurv researchers have fabricated a new high-performance shortwave infrared (SWIR) image sensor based on non-toxic colloidal quantum dots. In their study published in Nature Photonics, they report on a new method for synthesizing functional high-quality non-toxic colloidal quantum dots integrable with complementary metal-oxide-semiconductor (CMOS) technology.

Invisible to our eyes, shortwave infrared (SWIR) light can enable unprecedented reliability, function and performance in high-volume, computer vision first applications in service robotics, automotive and consumer electronics markets...

Face to Face with Sun-Eclipsing Proba-3

Through exquisite, millimeter-scale, formation flying, the dual satellites making up ESA’s Proba-3 will accomplish what was previously a space mission impossible: Cast a precisely held shadow from one platform to the other, in the process blocking out the fiery sun to observe its ghostly surrounding atmosphere on a prolonged basis.

Ahead of the Proba-3 pair launching together later this year, the scientists who will make use of Proba-3 observations were able to see the satellites with their own eyes...
