Last week was jam-packed with interesting news straight from the world of science. Today’s summary will include music from spider webs, opposing thumbs on pterosaurs and a floating laboratory.
Google Earth Timelapse shows how climate change has affected our planet
Google Earth Timelapse combines 24 million satellite images taken from 1984 to 2020, and it took thousands of machines to process these materials, for a total of about two million hours. I have to admit that the business impact is exciting, because satellite images cover the entire planet, not just the places that the experts choose. Among the proposed sites there are, among other things the coast of the United Arab Emirates, mining areas in Chile or melting glaciers in Alaska.
Thumbs up in the age of dinosaurs? Meet the “Poductil Monkeys”
The so-called monkeys lived on Earth about 160 million years ago and were pterosaurs. Its wingspan was about 85 cm, although from a scientific point of view it is not the dimensions that are the most important in this case, but the presence of an opposing thumb. The authors of the find believed that such an anatomical feature appeared in representatives of the species Kunpengopterus antipollicatus As part of an adaptation to life in trees.
Face recognition is used in permission to pay. The system will have billions of users
An analysis by scientists associated with Juniper Research shows that over the next few years, billions of people around the world will use facial recognition technology to allow payments via smartphones, tablets or smart watches. Fingerprint sensors were found in 93% of the first devices. In contrast, the number of users using voice recognition will increase to more than 704 million.

Scientists want to study the Alpha Centauri system. Information about the mission has been disclosed
As part of the Breakthrough Starsho mission, a miniature spacecraft will be attached to a lightweight and durable solar sail. The said sail will be driven by laser pulses that provide a velocity of 1/5 of the speed of light. In this way, scientists plan to send a historic mission to Alpha Centauri, the closest planetary system to ours. With such ultra-fast performance, a nanotransformer could travel 4.37 light years in just 20 years.
Earth 300 will be like a floating laboratory. There will be 160 scientists on board
Earth 300 is designed to search, explore the world, and take on today’s most important challenges. Its producer, Salas Jefferson, says up to 160 scientists can be on board at the same time. Earth 300 will also have a fleet of advanced submarines for deep exploration. The group will even include an air traffic control helicopter and take the crew to the ground and back.
Music was created from spider webs. In the future, this could ensure contact with spiders
Scientists assigned individual strings of the spider’s web to different sound frequencies, creating “notes”. Then they combined it into patterns that generate melody. The resulting sounds make up a chunk that lasts more than a minute and is very annoying. Argentine artist Tomás Saraceno participated in the project, the main role was the web woven by a spider-type. Cyrtophora Citricula.
We found out when was the boring day ever
William Tunstall-Pedoe in 2010 created an algorithm to search his now defunct website True knowledge, Which described more than 300 million facts related to, among other things, people and events over the years. Using this program, the man decided to objectively decide which day deserves to be called the most boring day in history. The winner was on April 11, 1954, when nothing happened that deserved more attention: Oldham sports player Jack Shufflebotham died and Turkish scientist Abdullah Atalar was born.

What strength could King Kong have if he really existed?
Rhett Allen of the University of Southeastern Louisiana concluded that the King Kong film was about 100 meters high and weighed about 42 million kilograms, or 42,000 tons. One of the most interesting calculations made by Allen is the potential power of a giant ape. His calculations show that such an animal could lift up to 7.5 million tons. For comparison, western gorillas can lift around 1,800 kilograms of weight.
T. rex was more than we think. Scientists have counted the number of individuals who have lived throughout the history of the Earth
Using fossil records, paleontologists have estimated that the average T. rex weighs 5,200 kg. As part of other calculations, scientists determined that as many as 20,000 individuals could exist on Earth at one time. Taking into account the fact that T. rex inhabited our planet for about 2.5 million years, it is possible to calculate the approximate total number of these species over the years: two and a half billion. This indicates that, on average, only one in 80 million individuals has been preserved and is found as a fossil.
Human and monkey creatures have survived for much longer than scientists expected
Scientists from China and the United States have created an illusion that combines the traits of humans and monkeys. The embryos survived for much longer than expected, with some for 19 days. Throughout the experiment, the percentage of human cells in the embryos remained constant at a high level. How might the conclusions of this type of research be helpful? Researchers hope that their achievements will translate into a number of benefits in the future, including in the form of growing organs for transplantation or drug testing.
