This article is part of a special issue that explores important questions about skin care. Check out the entire series here.
As we age, our skin inevitably loses some elasticity. Once upon a time, the main weapon against wrinkles and sagging, for those who could afford it, was the use of a surgeon's knife. Today, there are a wealth of minimally invasive alternatives that promise to tighten and rejuvenate our skin. There's everything from Botox injections to devices that shine light or ultrasound waves on your skin, to “vampire” facials that inject blood extracts into your face. .
Given that healthy skin has a wide range of health benefits, do these “tweaks” rejuvenate you from the outside in? “The question is, is this just vanity, or is it more important to your future self?” “Are you doing something useful?'' says the dermatologist. clare keeley At Guy's and St Thomas' Hospital, London. “It depends on the type of treatment.”
lost elasticity
Aging involves many changes, but the main cause of wrinkles is the loss of collagen and elastin, proteins that provide firmness and elasticity. Treatments such as Botox (an injection of botulinum toxin to prevent muscle contraction) cannot stop these changes, but when injected into specific facial muscles, it can be an effective way to prevent frown lines. There is a gender. Similarly, gel-like substances called dermal fillers, injected under the skin, can smooth wrinkles and add volume to sagging tissue, but they do not address underlying structural changes and are associated with risks.

A plant-eating sauropod dinosaur that evolved in a humid environment during the early Jurassic period.
Marcin Ambrozik
The contents of feces and vomit from 200 million years ago are helping to show how dinosaurs conquered the world at the beginning of the Jurassic period.
Whole insects embedded in various shapes and sizes of well-preserved plants, bones, fish parts, and even ancient animal feces show that dinosaurs varied in comparison to other groups of animals. This suggests that dinosaurs were able to survive in the ecosystem thanks to their wide-ranging diet. This led to their further growth and eventually led to the establishment of a “land dynasty.” Martin Kvarnström At Uppsala University, Sweden.
Fossil evidence shows that the first dinosaurs had prominent hip joints that placed their legs underneath their bodies like mammals, rather than sprawling sideways like lizards. More than 230 million years ago During the Triassic. For tens of millions of years, these early dinosaurs blended into a landscape filled with many other types of reptiles. But by about 200 million years ago, dinosaurs had essentially taken over the Earth, around the time most other reptiles disappeared during the end-Triassic extinction.
What led to this dominance remains somewhat of a mystery. Kvarnström and his colleagues suspected that important clues might be hidden in the bromalites (fossilized feces and vomit) of dinosaurs and other animals. So they Polish Geological Institute collected by a prior research group from eight locations in Poland between 1996 and 2017.
The research team estimated the age of each bromalite based on the layer of sediment in which it was found, and determined its size, which ranges from a few millimeters to a “fairly large fecal mass,” and the animals that may have produced it. A suitable shape was used. The researchers then 3D scanned the fossil to examine its contents. “We noticed that it was clogged with food debris,” Kvarnström says.
Coprolites, or fossilized feces, of herbivorous dinosaurs containing plant remains

Combining the known fossil record and past climate information, researchers determined that the emergence of dinosaurs occurred in several different stages. First, the omnivorous ancestors of early dinosaurs began to outnumber non-dinosaurs. They then evolved into the first carnivorous and plant-eating dinosaurs.
At that point, increased volcanic eruptions and movement of tectonic plates caused flooding and waterway development. The resulting humidity and related changes in climate likely led to a wider range of plants and the evolution of larger and more diverse herbivorous dinosaurs. On the other hand, animals other than dinosaurs (such as dicynodonts, which eat plants weighing up to 1 ton) Lisowisia, Their feces contained mainly coniferous debris and they were less able to adapt to changes in vegetation.
As herbivorous dinosaurs grew larger, so did their predators. By the beginning of the Jurassic period, about 30 million years after the first dinosaurs appeared, the transition to a dinosaur-dominated world was complete, Kvarnström says.
“This study shows how climate primarily affected dominant plants, which created opportunities for new herbivores at certain points in time,” he says. michael benton from the University of Bristol, UK, was not involved in the study.
Although it's difficult to be sure that the researchers matched the scat to the right animal, the discovery nonetheless suggests that the dinosaur species had already expanded significantly in South America before major climate change. This confirms earlier research, he says. “But it took the end-Triassic mass extinction for the final stage of the takeover to begin.”
for emma dunn The study, conducted at Germany's Friedrich-Alexander University, helps answer long-standing questions about the emergence of dinosaurs. “It's not every day that a fossil poop is published in such an influential journal,” said Dunn, who was not involved in the study. “This is obviously interesting, but it's also very useful for understanding prehistoric environments. So if you think of the evolution of early dinosaurs like a jigsaw puzzle with pieces missing, there are new It’s just a lot of pieces thrown in.”
