The scientific term for these huge puffballs is Calvatia Gigantea, which translates from Latin as "giant bald head"—exactly what they resemble. They appear in late summer and fall and like many mushrooms, they grow after a good rain. The huge mushrooms may grow anywhere there is organic matter, including forests, lawns and golf courses. They are common across Canada, particularly in Ontario, Quebec and British Columbia. "They do tend to show up in the fall like a lot of mushrooms actually. That's because they kind of show up when conditions of the humidity accumulates and then the nights start being a little cooler. Then this kind of combination of humidity, cool nights and then some warm days then you get these you know these mushrooms are popping out," said Richard Hamelin, a professor at the University of British Columbia in the faculty of forestry and environmental stewardship.

Evidence for intelligent design in nature may be clear to you, while other matters relevant to faith remain far more perplexing. Our physicist colleague Brian Miller talked with Jana Harmon on the eX-skeptic podcast, in a very personal conversation, and offered a helpful analogy. He agreed that, for him, there are “tensions” and “unanswered questions.” But here’s the difference. When you have, let’s say, a magnifying glass and you use that magnifying glass to see the small print on your medicine bottle, what happens is that [with the] magnifying glass, what’s in the center is very clear.

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.

Forests that stood on Mozambique's coast thousands of years ago now lie beneath shallow seas, and they have become fish-filled "peat reefs" with marine life comparable to coral reefs, researchers report in Scientific Reports. A team from the Bazaruto Center for Scientific Studies (BCSS) Ocean Observatory, led by Mario Lebrato, documented the submerged peat in the Bazaruto Archipelago in the Western Indian Ocean. BCSS, founded in 2017, describes itself as Africa's first permanent ocean observatory. Working with universities and institutions in the U. K., U. S. and Canada, the team believes it has carried out the first ecological study of peat reefs anywhere in the tropics. Old forests, new seafloorRadiocarbon dating shows the peat formed between about 300 and 5,000 years ago, and chemical analysis indicates it came mostly from coastal land plants and trees. Some samples contain up to 40% organic carbon by dry weight. Lebrato said the coastline has very little natural hard seabed, mostly shifting sand. As rising seas expose the old peat layers, they create rare solid habitat where marine life can settle, hide and feed.
