➽➜P⇢➤BIRDS The Climate Crisis Is Making Birds Smaller
North American birds are getting smaller, a study published Wednesday in Ecology Letters has found, and scientists think the climate crisis is to blame.
Researchers from the University of Michigan and the Field Museum in Chicago studied 70,716 dead birds from 52 different species, including sparrows, thrushes and warblers, that were collected between 1978 and 2016, according to CNN. They found that 49 species got smaller by a statistically significant degree.
“We found almost all of the species were getting smaller,” lead author and assistant professor at the University of Michigan’s School for Environment and Sustainability Brian Weeks told BBC News. “The species were pretty diverse, but responding in a similar way. The consistency was shocking.” https://www.ecowatch.com/climate-change-bird-size-2641523464.html?rebelltitem=1#rebelltitem1

➽➜P⇢➤Physicists Have Discovered a Metal That Conducts Electricity but Not Heat
Not only does this change what we know about conductors, it could also be incredibly useful. (TMU) — A team of researchers in the United States have defied what we have always believed to be true about the intimate relationship between electricity conduction and heat. Conductors are no longer behaving as some physical laws stated. https://themindunleashed.com/2019/12/metal-conducts-electricity-but-not-heat.html

➽➜P⇢➤Is the Great Red Spot of Jupiter About to Disappear Forever?
Jupiter’s Great Red Spot is not dying, scientist says. (CONVERSATION) — In the last 10 years, but in the last five months in particular, the press has reported dire warnings that the Great Red Spot of Jupiter is dying. However, some astronomers believe, to paraphrase Mark Twain, that the reports of its death are greatly exaggerated, or at least premature.
Robert Hooke, an early British physicist who discovered cells, first described the Great Red Spot in 1665. In 1979, when two Voyager spacecraft flew close by Jupiter, images showed that the spot was a red cloud that rotated as part of a huge vortex several times larger than the Earth. https://themindunleashed.com/2019/11/great-red-spot-of-jupiter-dying.html
➽➜P⇢➤The 11 Biggest Unanswered Questions About Dark Matter In the 1930s, a Swiss astronomer named Fritz Zwicky noticed that galaxies in a distant cluster were orbiting one another much faster than they should have been given the amount of visible mass they had. He proposed than an unseen substance, which he called dark matter, might be tugging gravitationally on these galaxies. https://www.livescience.com/64113-dark-matter-mysteries.html
➽➜P⇢➤Long-Standing Problem of ‘Golden Ratio’ and Other Irrational Numbers Solved with ‘Magical Simplicity’ Most people rarely deal with irrational numbers—it would be, well, irrational, as they run on forever, and representing them accurately requires an infinite amount of space. But irrational constants such as π and √2—numbers that cannot be reduced to a simple fraction—frequently crop up in science and engineering. These unwieldy numbers have plagued mathematicians since the ancient Greeks; indeed, legend has it that Hippasus was drowned for suggesting irrationals existed. Now, though, anearly 80-year-old quandary about how well they can be approximated has been solved. https://www.livescience.com/irrational-numbers-golden-ratio-conjecture-solved.html
