A fox family with seven babies living under an Etobicoke home shed are now the unsuspecting stars of their own ongoing movie. Toronto couple Jason Tremblay and Katelyn Darlington, both paramedics in Peel, are live-streaming on YouTube the comings and goings of the red fox father, black fox mother and their seven kits, which they discovered in their backyard two weeks ago.
In moments of peril, superheroes don’t hesitate, they leap into action. And so, it seems, do little boys if their baby sister’s life depends on it. When 8-year-old Jaxson Dempsey realized his 20-month-old sister Lelia was choking on a chicken nugget, he didn’t panic. Instead, he calmly directed his dad to pull over the car they were driving in and proceeded to dislodge the obstruction from Lelia’s airway. Jaxson said he’d learned the lifesaving technique from watching WWE superstar John Cena perform the maneuver on an episode of the Nickelodeon show The Substitutes. Jaxson’s father Matt has nothing but gratitude for his son, whose quick thinking staved off a potential tragedy. “I couldn’t hear her because she was choking. She wasn’t coughing; she wasn’t panicking. She just had no air going through; she wasn’t breathing,” Dempsey told WNEP-News. “Thank God Jaxson was there because, without him, I don’t know if Lelia would be here.” While kudos were the last thing on Jaxon’s mind for doing what came naturally when his sister needed him, they’ve been rolling in nonetheless ever since.
A patient with a genetic form of childhood blindness gained vision, which lasted more than a year, after receiving a single injection of an experimental RNA therapy into the eye. The gene editing research was conducted at the Perelman School of Medicine in the University of Pennsylvania. Results of the case, detailed in a paper published April 1 in Nature Medicine, show that the treatment led to marked changes at the fovea, the most important point of human central vision. In the international clinical trial, participants received an intraocular injection of an antisense oligonucleotide called sepofarsen. This short RNA molecule works by increasing normal CEP290 protein levels in the eye’s photoreceptors and improving retinal function under day vision conditions. The treatment was designed for patients diagnosed with Leber congenital amaurosis (LCA) — an eye disorder that primarily affects the retina — who have a CEP290 mutation, which is one of the more commonly implicated genes in patients with the disease. Patients with this form of LCA suffer from severe visual impairment, typically beginning in infancy.
In the country’s oldest science fair, 17-year old high schooler Dasia Taylor submitted a surgical suture that changes colors to warn of possible infections. This invention, aimed at helping surgery patients in Africa detect infections before they become serious, elevated Dasia into the 40 finalists of the national Regeneron Science Talent Search. The sutures are the perfect solution to a problem which Smithsonian Magazine summarizes—where not only are post-surgical infection rates typically higher in Africa, but expensive, smartphone-based infection early warning systems aren’t practical in many African countries where basic cell phones are widely used, but not smartphones. Beginning her project back in 2019 in her chemistry class at Iowa City West High School, the process from theory to practice ended up winning Dasia several regional science fair prizes. Her method uses beetroot, famous as any cook knows for turning everything red and purple. The pH of our skin is acidic and averages at 5, while an infected wound raises that pH to a level of 9, and as it turns out beets change color from candy apple red to deep purple as the pH level of its environment grows.
When a wildfire destroys the forest on your property, what are your options for restoring what has been lost? DroneSeed will fly a squadron of seed-dispersing aerial robots to lay the foundations for a new forest atop ones that have been torched. Carrying 57 pounds of tree seeds, the drones weigh over 100 pounds in total, and operate in teams of five using satellite-guided software to identify hundreds of “microsites”—areas where trees will be expected to grow the best. Holders of the only Federal Aviation Administration license for operating “heavy lift drone swarms,” DroneSeed can seed the ground 6x faster than hand-planting seedlings can—covering around 40 acres per day at a cost of around $275 to $400 per acre. This may seem like a lot, but as well as saving a huge amount of time—a lot of the cost can be offset with discounts offered by DroneSeed if they can successfully offer the land’s reforestation as carbon credits on the global carbon market. This can help make the cost of planting seedlings 60-70% less than traditional reforesting.
