This month we have new works by several big name authors. Cixin Liu and Ann Leckie both have easy-to-read collections of short texts. It also depicts a dystopian future by award-winning Thea Obret, and a world where woolly mammoths have been brought back from the world. Douglas Preston's bestseller.He also loves the sound of Scott Alexander Howard's debut song another valleya town where past and future versions exist in the following valleys, and the space adventures of Sofia Samatar. Practice, horizon, and chain. There are so many things I want to read and not enough time…

This is a collection of short stories by science fiction author Liu, who is currently on the rise thanks to a new Netflix film. three body problem, from essays and interviews to short stories. I love this excerpt from an essay about science fiction fans. In it he calls us “mysterious aliens in the crowd.” They “jump like fleas from the future to the past and back again, floating like gas clouds between nebulae. In an instant we can reach the edge of the universe or tunnel into quarks.” or swim inside the core of a star.''Aren't we lucky to have a world like this on our shelves?

Leckie is a must-read author for me, and this is the first complete collection of her short stories, ranging from science fiction to fantasy. On the sci-fi side, we'll be able to dip in again. imperial latch And we're also promised to “learn the secrets of the mysterious Lake of Souls” in a brand new novel.

In the disastrous future, an 11-year-old girl arrives in Morningside with her mother. Once a luxury high-rise, Morningside is now another crumbling part of Island City, half submerged under water. Obrecht won the Orange Prize for Fiction in 2011 for her debut novel. tiger's wife.

Samatar won all kinds of awards for his first novel. Stranger in Olondria. Her latest work depicts the story of a boy who grew up working on a mining ship in the stars, but whose life changes when he is given the opportunity to receive an education at the ship's university. Sounds interesting.

It's set in a Rocky Mountain valley, where guests at the luxury resort can see woolly mammoths, giant ground sloths and Irish moose brought back from extinction through genetic engineering. But then a series of murders begins, and the two investigators must find out what's really going on.this is what it looks like Jurassic Park-It looks like a lot of fun. And if you want more mammoth-related reading, try my colleague Michael Le Page's excellent explanation of why they won't be coming back anytime soon.

The award-winning author we have to talk about kevin Reflecting her thoughts on the so-called “culture wars” in her fiction, she imagines a world where the “spiritual equality movement” is at its peak, and “the worst thing you can do is call someone 'stupid'.” There is.

This speculative novel alternates endlessly through the wilderness, with the same town to the east 20 years ahead of its time, and the same town to the west 20 years behind. Border crossings are only allowed on “memorial tours,'' which allow people to see the dead in towns where they are still alive. Odile, 16, will take a seat on the Conseil Commission, which can decide who can travel across borders. I love this sound.

Many may wonder if Marvel's superhero stories are really science fiction, but I'm leaning toward the multiverse aspect of this here and including it because it seems kind of interesting. This is the first installment in a new series that reimagines the origins of some of our biggest heroes. Here, Thor died defending Earth from Loki's pranks, and the Norse trickster god, exiled to our planet, is now dealing with the consequences.

the second book of eternal desert The series is set 500 years in the future. Ajungo's lie, which follows a junior peacekeeping force in the last remaining free city in the Eternal Desert, which has been under siege for centuries. It was actually released in March, but I missed it then, and science fiction contributor Sally Addy introduced it as a title to watch this year, so I'm introducing it now.

The Unexpected Advantages of an Asymmetric Face, Body, and Brain

When you look in the mirror, you may notice slight imbalances in your facial features, such as your nose crooked to the left, a wrinkle that only appears under one eye, or your ears slightly higher than the other. .

For centuries, this lack of perfect balance has been thought to detract from our beauty, and there are a number of services aimed at “fixing” it, from photo filters to cosmetic surgery. But asymmetry is built into the human body and brain, and for good reason. Moreover, new research suggests that it has little effect on your appeal to others.

First, lopsided arrangement of our internal organs. For most people, the heart, stomach, and spleen are all on the left side of the spinal cord, and the liver and gallbladder are on the right side. This makes more efficient use of thoracic and abdominal space compared to a structure that aligns all organs to the spine.

Why is the human brain asymmetrical?

What about your brain? Although her two hemispheres may appear to be reflective of each other, corresponding areas on each side have different responsibilities. You will notice the effect this has on your movements. If you're right-handed, it's because the left hemisphere of your brain, which is connected to the right side of your body, is slightly more specialized in controlling the fine muscles of your fingers, increasing your manual dexterity. .

You may be surprised to find that this “lateralization” is seen in many fields…

Researchers can now estimate your biological age based on a snapshot of your body

It is now possible to measure a person’s biological age, which refers to the wear and tear of the body’s cells, as opposed to the chronological age based on the number of years lived. Chinese scientists have developed a new method to predict biological age using artificial intelligence to analyze 3D images of the face, tongue, and retina.

This approach provides a way to estimate biological age more accurately than previous methods that primarily relied on DNA or blood tests and brain scans. By combining images of the face, tongue, and retina, scientists have created a model that can accurately predict biological age. This allows for easier, more accessible, and less invasive methods to estimate a person’s biological age compared to traditional tests.

Research from China’s Macau University of Science and Technology and Shanghai Jiao Tong University involved testing this model on healthy individuals and those with chronic diseases. The results showed that the biological age of individuals with chronic diseases was significantly higher than their chronological age compared to healthy individuals, indicating the potential impact of chronic diseases on aging.

Furthermore, this new method could also be used to assess the effectiveness of anti-aging treatments, such as diet, exercise, and longevity drugs. Dr. Andrew Steele, a longevity expert, highlighted the potential for using photos to evaluate the efficacy of anti-aging strategies and speed up clinical trials in the future.

Starfish possess only a substantial, compressed head and lack a body.

Scientists trying to figure out where the starfish’s head is located have come to the surprising conclusion that the starfish is practically the entire body of the animal. The discovery not only solves this long-standing mystery, but also helps us understand how evolution created the dramatic diversity of animal forms on Earth.

Starfish, also known as sea stars, belong to a group of animals called echinoderms, which includes sea urchins and sea cucumbers. Their strange body design has long puzzled biologists. Most animals, including humans, have distinct cranial and caudal ends, and a line of symmetry runs down the middle of the body, dividing it into two halves of its mirror image. Animals with this bilateral symmetry are called bilateral animals.

Echinoderms, on the other hand, have five lines of symmetry radiating from a central point and no physically obvious heads or tails. However, they are closely related to animals like us, having evolved from bilaterally symmetrical ancestors. Even larvae are bilaterally symmetrical and then radically reorganize their bodies as they metamorphose into adults.

These large differences make it difficult for scientists to find and compare equivalent body parts in bilateral animals to understand how echinoderms evolved. “Morphology tells us very little,” he says. Laurent Formery at Stanford University in California. “That’s too strange.”

Formalie and his colleagues decided to examine a set of genes known to direct head-to-tail control. All bilateralist organizations. In these animals, these genes are turned on and expressed in stripes in the outer layers of the developing embryo. The genes expressed in each stripe define which point it is on the cranio-caudal axis.

The aim was to see if gene expression patterns could reveal the hidden “molecular anatomy” of echinoderms. “This particular gene suite is ideal for investigating the diversity of the most extreme forms of animals,” says the team leader. chris lowe, also at Stanford University. “I think echinoderms are a very extreme experiment in how to use that bidirectional network to produce very, very different body plans.”

To the team’s surprise, the gene that determines the head edge of bilateral animals was expressed in a line running down the center of each star star’s lower arm. The next leading gene is expressed on both sides of this line, and so on.

Even more bizarrely, genes normally expressed in the trunk of bilateral animals were missing from the animals’ outer layers. This suggests that the starfish abandoned its trunk region and released its outer layer to evolve in a new direction, Formery said.

The findings show that “the bodies of echinoderms, at least with respect to their external surfaces, are essentially lip-walking heads.” Thurston Lacari from the University of Victoria, Canada, was not involved in the study. Animals like us may have swam away to escape predation. “Echinoderms didn’t need trunks because they were hunched over and armored,” Lacari says.

The idea that echinoderms are “head-like” animals is “interesting and powerful,” he says. Andreas Heyland at the University of Guelph in Ontario, Canada. This raises some very important and fundamental questions about how ecological factors shape the evolution of anatomy, he says. “Finding the underlying conserved patterns provides important insights into how development evolves.”
