There's a rare, inherited sight condition, involving faulty copies of the CaBP4 gene, that causes poor vision from childhood. The protein made by the gene is crucial for chemical signaling in the retina. It's also something that can affect dogs – and in treating pooches, researchers have discovered a therapy approach that promises to be transformative. In a study published in Molecular Therapy Advances, researchers led by a team from Michigan State University in the US report that a single-dose gene therapy treatment not only stopped blindness from progressing, it physically repaired damaged connections. It raises the tantalizing prospect of treatments that can repair nerve cells in mammals, something which had previously been thought by many to be impossible. "We were able to show three independent structural changes supporting plasticity in the adult retina," says veterinary ophthalmologist Billie Beckwith-Cohen, from Michigan State University. "Not only were new components added, but pre-existing abnormalities were repaired.

The building is 30 feet away from the edge of the Don Valley Parkway, which is a safety concern for travelling cars and the demolition crew. Janice Golding repo A portion of the Don Valley Parkway is closed until Friday morning, as a building next to the highway is being demolished after it was destroyed by a massive fire. City officials said the northbound lanes of the DVP are blocked from the Gardiner Expressway to Dundas Street until 6 a.m. The fire broke out at 2 Matilda St. shortly after 9:30 p.m. on Wednesday. The building is located adjacent to the highway, just south of Dundas Street. Historic warehouse in Riverside erupts in flames: Fire crews investigating suspicious circumstances Historic warehouse in Riverside erupts in flames: Fire crews investigating suspicious circumstances “As the building is only approximately 30 feet away from the edge of the Don Valley Parkway, the roadway needs to be closed during that demolition to ensure the safety of both the travelling public and the demolition crews,” Ashley Curtis with the City of Toronto’s Transportation Services, said in a news conference on Thursday afternoon. “The work will be completed overnight to minimize disruption

Milky Way’s first microblazar candidate sits 12,000 light-years away, offering a rare ground-level lab for studying relativistic jetsA black hole 12,000 light-years away is firing a jet of plasma almost directly toward Earth. At that distance, no known or expected danger to Earth has been identified by the researchers or the institutions involved. What astronomers have actually found is rarer and more interesting than a threat. Researchers have identified IRAS 18293-0941 as a compelling candidate for the Milky Way’s first microblazar, a class of object that gives astrophysicists a close-up laboratory for studying some of the most violent physics in the galaxy. What Astronomers FoundThe discovery centers on a binary system whose black hole expels plasma jets at close to three-quarters the speed of light, pointed almost directly toward Earth. The system pairs a hot, massive star with a black hole that completes a full orbit roughly every 11.38 days. Material drawn from the companion star feeds the black hole, and some of that matter gets expelled outward as opposing jets traveling at approximately three-quarters the speed of light. Terminology matters here.
