The second law of thermodynamics is among the most sacred in all of science, but it has always rested on 19th century arguments about probability. New arguments trace its true source to the flows of quantum information.
Theoretical physicist Marcelo Gleiser raises the issue that the multiverse hypothesis suffers from the unscientific property of non-falsifiability. Embedded in his article is a solid acknowledgement of the fine-tuning of physical parameters for life to exist in our universe.
In his lengthy article, Bell draws attention to evolutionary hurdles to the origin of eukaryotic cells. The “chasm” between eukaryotic and prokaryotic cells is causing a re-think of the universal common ancestor notion.
Davide Castelvecchi: Chemists say they have solved a crucial problem in a theory of life’s beginnings, by demonstrating that RNA molecules can link short chains of amino acids together.
In an article summarized at The Conversation, recent research affirms the suite of conditions involving plate tectonics and resultant mountain-building, coupled with erosion and volcanic activity, that has helped to maintain a habitable climate on our planet.
Astrophysicist Jeff Zweerink reminds us that the theoretical prediction of black holes and their subsequent discovery highlights the comprehensibility of the universe by human minds–even relating to phenomena far beyond anything in our experience.
The next couple of nights will offer early-morning sky-watchers the opportunity to view our nearest planetary neighbors (going outward from the sun) appearing to be separated by only about the width of a full moon.
An updated giraffe genome, published March 17, 2021 in Science Advances, reveals new insights into how the species accommodates a “blatantly strange body architecture.”
For those who have eyes to see, nature reveals design across the scientific disciplines.
Jeff Zweerink, senior research scholar at Reasons to Believe, discusses the movement efficiency of Kinesin-1 in the context of a perceived design inefficiency in the reconnaissance aircraft SR-71.
Sean Raymond, Beibei Liu & Seth Jacobson offer a solar system model affirming that the “dynamical instability” of our early solar system had to go just right, or we probably wouldn’t be here.
Astronomy: Time is an elusive concept: We all experience it, and yet, the challenge of defining it has tested philosophers and scientists for millennia.
Bechly: In the end, Farina’s potshots against intelligent design and Discovery Institute completely miss their targets. “Professor Dave” needs to do more than recycle past discredited claims if he wants to be taken seriously by anyone genuinely interested in pursuing the truth.
The stunning imagery shows previously known and newly-discovered features, including supernova remnants, huge magnetised radio filaments and the blazing inferno surrounding the 4-million-solar-mass black hole at the core of the galaxy.
Researchers have untangled the intricate physics and neural controls that enable dragonflies to right themselves while they’re falling.
