In a recent study that was sent to MNRAS, a group of researchers worked together to use the first batch of data from the James Webb Space Telescope (JWST) to find a candidate galaxy, CEERS-93316, that formed about 250 million years after the Big Bang and set a new record for redshift with a value of z = 16.7. This discovery is very exciting because it shows how good JWST is, even though it has only just started sending back its first set of data. The Cosmic Evolution Early Release Science Survey, or CEERS, was made so that it could be used with JWST to take pictures.

“The past few weeks have been surreal, watching all the records that stood for a long time with Hubble be broken by JWST,” says Dr. Rebecca Bowler, who is an Ernest Rutherford Fellow at the University of Manchester, and a co-author on the study. “Finding a z = 16.7 galaxy candidate is an amazing feeling – it wasn’t something we were expecting from the early data.”

This new study talks about a dozen previous studies that measured objects up to redshifts z 10 using a mix of ground-based observations and the Hubble Space Telescope and Spitzer Space Telescope.

Recent work has reported a realization of a time crystal in the form of the Bose-Einstein condensate of magnons in superfluid 3He. Here, the authors study the dynamics of a pair of such quantum time crystals and show that it closely resembles the evolution of a two-level system, modified by nonlinear feedback.

Octopuses have fascinated scientists and the public with their remarkable intelligence, from using tools to engaging in creative play, problem-solving, and even escaping from aquariums. Now, their cognitive abilities may provide significant insight into understanding the evolution of complex life and cognition, including the human brain.

An international team of researchers from Dartmouth College and the Max Delbrück Center (MDC) in Germany has published a study in the journal Science Advances.

<em>Science Advances</em> is a peer-reviewed, open-access scientific journal that is published by the American Association for the Advancement of Science (AAAS). It was launched in 2015 and covers a wide range of topics in the natural sciences, including biology, chemistry, earth and environmental sciences, materials science, and physics.

Biological molecules, like organisms themselves, are subject to genetic drift and may even become “extinct”. Molecules that are no longer extant in living systems are of high interest for several reasons including insight into how existing life forms evolved and the possibility that they may have new and useful properties no longer available in currently functioning molecules. Predicting the sequence/structure of such molecules and synthesizing them so that their properties can be tested is the basis of “molecular resurrection” and may lead not only to a deeper understanding of evolution, but also to the production of artificial proteins with novel properties and even to insight into how life itself began.

There’s still nothing quite like thumbing the pages of a real-life print magazine, but the latest evolution of E Ink’s color tech is creeping tantalizingly close — at least as far as my eyes are concerned.

You’ve heard it all before: A lifetime of staring at screens has worn out my eyes, leading me down a rabbit hole of lifehacky solutions to ease the fatigue. Some of the tricks I picked up over the years have helped — especially the one where I simply take breaks and go for walks — but one thing hasn’t changed: I still spend more time than I’d like gazing at glossy displays.

Scientists who watched nerve cells connect inside the eyes of growing squid have uncovered a remarkable secret — the cephalopods’ brains independently evolved to develop in the same way ours do.

.The discovery, made using high-resolution cameras focused on the retinas of longfin squid (Doryteuthis pealeii) embryos, reveals that, in spite of 500 million years of divergent evolution, the basic blueprint for how complex brains and nervous systems evolve may be the same across a wide range of species.

The intelligence of cephalopods — a class of marine animals that includes octopuses, squid and cuttlefish — has long been a subject of fascination among biologists. Unlike most invertebrates, these animals possess remarkable memories; use tools to solve problems; excel at camouflage; react with curiosity, boredom or even playful malevolence to their surroundings; and can dream, if the ripples of colors that flash across their skin as they sleep are any indication.

In this video I showcase a program that I have been working on for simulating evolution by natural selection. I dive into various mechanisms of the simulation and go over some interesting real-life biology in the process. The key aim of this project is to evolve multicellular organisms, starting from single-celled protozoa-like creatures that must collect mass and energy from their surroundings in order to survive, grow and reproduce.

00:56 — Life of a protozoan.

Chinese scientists precisely confirmed the latest volcanic activity on moon happened about 2 billion years ago after they studied the lunar samples collected by Chang’e-5 lunar probe in 2020.

The outcome was announced by the China National Space Administration on Monday.

In 2021, a team of scientists carried out researches on the volcanic rock, which is a type of basalt to help indicate the time of volcanic activity occurred, from the lunar samples and proved that the volcanic activity continued until 2 billion years ago, a new refresh for human beings toward the lunar magmatic activity and the lunar evolution.
