“The state government should consider managing the invasive population of spotted-thighed frogs at Streaky Bay. This should include education programs to inform people about what to do if they find a frog, as well as the feasibility of exterminating the population in South Australia.

“Importantly, if you do see one of these critters in your travels – leave it be. We don’t want it hitchhiking any further.”

While watching the launch of SpaceX Crew Dragon, I noticed that, once the astronauts came out of the elevator in the fixed service structure, they had to ‘climb up’ one level using the stairs, before entering the white room through the crew access arm. I’m curious to know why doesn’t the elevator take them directly to the crew access arm level?

Earlier, I thought the reason might be due to the height difference between the side hatches on the Space Shuttle and Crew Dragon. But after seeing the following image it became evident that the difference is more than one level:

It has previously been discovered that tanycytes—cells found in part of the brain that controls —detect nutrients in and tell the brain directly about the food we have eaten.

Tanycytes do this by responding to found in foods, via the same receptors that sense the flavor of amino acids (“umami” taste), which are found in the taste buds of the tongue.

In the paper ‘Hypothalamic tanycytes generate acute hyperphagia through activation of the arcuate neuronal network.’ published today, the 8th June, in the journal PNAS, researchers from the School of Life Sciences at the University of Warwick, explain how tanycytes can increase appetite.
