Researchers found evidence of a possible planet around the white dwarf HS 0209+0832, using old observations from NASA’s Hubble Space Telescope.

Hubble first recorded about 100 chemical signatures it could not identify in this system in 1999.

The team matched many of those signatures to niobium, an element that can form in the unusual conditions inside dying stars.

The amount detected was about 1,000 times the level in our Sun, pointing to a planet made from material shed by the star.

Yale researchers found that lacosamide may help treat osteoarthritis, a condition in which joint cartilage wears away.

Current treatments can ease pain, but do not repair the cartilage; severe cases may require joint replacement surgery.

In tests using mice and human cartilage cells in the lab, lacosamide slowed cartilage damage, encouraged repair and reduced pain.

The drug blocks Nav1.7, a protein involved in pain signals and the balance between cartilage breakdown and repair.
