Today's bite sized chunks of good news.

  • A rescue cat helps children: Danielle Crull, an optician in America, rescued Truffles five years ago and trained her how to sit and to give high fives. She then decided to teach her how to wear glasses, thinking it might help nervous children, and it's been a huge success! "It's just like magic," Crull told Today. "As soon as the kids see her, they're like, 'Okay, glasses are amazing.'"

  • If the sight of a ship apparently hovering above the sea is a very rare event in the UK, then two in a fortnight is remarkable. Recently a giant tanker was pictured floating above the water off Cornwall - an optical illusion known as a superior mirage - and now a similar image has emerged of a cruise ship off the Dorset coast. But hang on, cruise ship? Actually, cruise ships that would usually be in far-flung locations are now simply being anchored off the English coast.

  • Why do hummingbirds hum? Finally, scientists unlock the secret and take the “hmm?” out of hummingbirds.

  • Synergy: Vivaldi and Canaletto - You can’t get a closer match between sound and vision than these two 18th-century Venetian greats. To kick off a new online concert series, Orpheus Sinfonia play from this beautiful gallery. Wallace Collection online, this evening at 6pm GMT (and any time thereafter).

  • The Trump administration deleted the U.S. Environmental Protection Agency's main climate change webpage in October 2018. Now, it's back. The EPA announced that it rebooted its climate webpage, which includes information about how the climate is warming and how the regulatory agency seeks to curb heat-trapping greenhouse gas emissions. "Climate facts are back on EPA's website where they should be," the new EPA Administrator Michael Regan said.

  • It may look like a power station with a golf course on it, but it's actually the world's cleanest waste-to-energy power plant with a ski slope on it. OGN featured Copenhagen's Amager Bakke last year in Hedonistic Sustainability, and this new photo shows the landscaping around the winding green ski slope has bedded in, so the whole sloping side of the power station looks like a bright green hillock. Starting at a height of 90m, the 400m long slope makes a 180 degree turn as it twists down to ground level - to the lift back to the top.

  • EV battery swapping service: Batteries are the single most expensive component in electric vehicles. Wouldn't it be a good idea to remove the battery from the upfront cost and to swap the running cost of your old petrol car to renting the battery in your new electric car in order to make your EV substantially cheaper?

  • A small parade of rescued young sea turtles has headed into the Gulf of Mexico from Louisiana - a bright note in a tough season for sea turtles. The 13 released at Grand Isle were among more than 1,100 cold-stunned turtles that have been rescued and re-released in recent weeks in America.

  • Amazonian psychedelic: The pyschedelic that's used in shamanic rituals by Amazonian tribes is to be trialled as a treatment for depression.

  • UK achieves Covid vaccine milestone as more than half of all adults have now had their first jab. Yesterday was the biggest day yet for UK vaccinations, with more than 711,000 doses administered.

  • Today's shameless nature video: Single swimming sloth looking for love...
