Genetic analysis of bones and teeth found in caves in Siberia is helping to decipher the social and family structure of Neanderthals. Little is known about how the species came together: remains of bones and teeth found in two Siberian caves are helping scientists decipher the social structure of the Neanderthals. By sequencing the DNA of these relatives of modern humans, the researchers analyzed the social life of a community of species that lived about 54,000 years ago. For the study, published Wednesday (Oct. 19), scientists analyzed the DNA of 13 Neanderthals, eight adults and five children and teenagers, and found an interconnected web of relationships, including father and daughter, and possibly an aunt or grandmother and nephew. The analysis also showed that all Neanderthals were blood relatives, indicating that the communities consisted of small groups of close relatives numbering 10 to 20 people. The study also concludes that it was women who migrated to other communities, while men tended to stay where they were born. Scientists believe that at least 60% of women came from other communities to join the families of their partners. The caves were the base of the group, which roamed the surrounding areas in search of raw materials and food. In addition to samples, numerous stone and bone tools were found in the Chagr caves. According to the researchers, hunting for horses, bison and other animals in the river valleys of the region provided the population with meat and skins. One of the largest genetic studies of Neanderthals. The analysis also found no evidence of interbreeding between Neanderthals and Denisovan hominids, the remains of which were found 100 kilometers from the caves from which the samples were taken. Published in the journal Nature, this is one of the largest genetic studies ever conducted on the Neanderthal population. The study was conducted by scientists from the Institute of Evolutionary Anthropology. Max Planck, including this year’s Nobel Prize in Medicine laureate Svante Paabo. Previous research has shown that Neanderthals were more sophisticated than previously thought, adopting customs such as burying the dead and making elaborate tools and jewelry. However, little is known about their family and social structure. “Our discoveries make Neanderthals closer and in some ways more human. They lived and died in small family groups, probably under extreme conditions. However, they managed to survive for hundreds of thousands of years,” said population geneticist Benjamin. Peter, co-author of the study. Who were the Neanderthals Neanderthals are a subspecies of archaic humans who split from modern humans between 315,000 and 800,000 years ago. Experts believe that its population ranged from 3,000 to 12,000 individuals that bred before becoming extinct 40,000 years ago. The small population has made this species prone to decline due to disease, low fertility, and competition with other animals. The reason for their disappearance remains a mystery, but theories include climate change, disease, and the emergence of modern humans. Compared to modern humans, Neanderthals had a stronger body and shorter limbs. Experts believe that they were hardy and could retain body heat well to live in cold climates. Previous research has shown that Neanderthals treated the sick with painkillers and penicillin made from plants and fungi. Fossils of species found show that 79% to 94% of them had some kind of traumatic injury. One study found that 74% of samples analyzed had injuries caused by animal attacks. The first Neanderthal genome was sequenced just over a decade ago by Paabo and other scientists at Max Planck. This work earned Paabo the current Nobel Prize. The study, published on Wednesday, is a continuation of that first sequence. cn/ek (DW, Reuters, DPA, AFP)

Adobe Fresco is now available in the Microsoft Store

Adobe Fresco is now officially available for download from the Microsoft Store, giving users a new way to access the Adobe digital painting app. Previously, the app was only available through the Adobe website. The store version is still provided and managed by Adobe, which means it is not actually hosted on the Microsoft platform. Either way, it was an easier way to access it.

Adobe Fresco is now available in the Microsoft Store

Fresco is one of Adobe’s most advanced creative tools, a digital drawing and painting application designed primarily for touch devices. It’s actually available on iPad and iPhone, but not on macOS. So it’s really designed for touch screens, even on Windows 11.

According to Adobe, Fresco has the largest and “most advanced selection of brushes” in the world, thousands of which are available in the Adobe Library. The purpose of this app is to mimic real life as much as possible. So when you use watercolor for example, you will see the colors blend in real time. You can also paint in oils and use many other tools to create your desired piece of art. Fresco supports layers, layer masks and other features you would expect from a graphic design tool. Because it’s part of the Adobe Creative Cloud, it’s also linked to assets from Photoshop or Illustrator.

Meanwhile, in addition to being able to share finished work, Fresco has built-in real-time streaming capabilities to make it easier for you to share your knowledge with others. Plus, you can export a time-lapse of your drawing and painting process when you’re done.

However, this version of Fresco lacks support for ARM-based devices such as the Surface Pro 9 with 5G or the Surface Pro X. This is what Adobe originally promised back in 2019 when Surface Pro X arrived. Three years later, he still hasn’t done it. Recently at the Snapdragon Summit, the company confirmed its intention to release an ARM version in 2023, so let’s hope it won’t be long.

xrOS: Apple’s augmented reality glasses will get a new operating system

xrOS: óculos de realidade aumentada da Apple terão novo sistema operacional

fans Apple waiting for the launch of the headset augmented reality (RA) companies at the beginning of 2023 – in January, to be more precise; however, the change was revealed in an interesting detail. The tech giant announced that the hardware operating system will be called “realityOS‘, however the name will be xroOS, according to the latest reports. The effort invested by the pros has increased in recent months, indicating that the launch of the device is close.

According to recent announcements, Apple’s operating system for the augmented reality headset will be called xrOS.

One suggested reason for the name change is that the “xrOS” designation for international consumers will make it easier to identify the type of content that will be projected with the AR headset. Letters”XR” is an abbreviation for “andXcourted Rreality”, indicating the availability of resources possible with augmented reality, in free translation and interpretation.

Apple’s augmented reality glasses still don’t have a set release date

That is: based on the assumption that the equipment will play mixed content such as RA, as well as virtual reality resources (van), the consumer will be informed about what can be found easily. On the one hand, part of the intended experience is to combine real-time graphical information with the use of the environment and, at the same time, immerse the person in a differentiated experience with aspects of virtual reality, with a headset display.

The equipment will be able to play mixed content, such as AR itself, as well as virtual reality (VR) resources.

Because these approaches require powerful resources to run, despite being portable and lightweight, the hardware must also be powerful. Users will have access to new applications designed to provide unique experiences using product features. A wide range of options is expected, such as cards, messengers adapted for the mentioned technologies and much more.

Unfortunately, while the news was positive for those concerned, sources weren’t able to pinpoint the launch window. Therefore, many expect the presentation to take place in early 2023. Expectations are recommended to be controlled, because this is Apple’s first attempt in the segment, and unforeseen events may occur.

Portugal has been “sending” SMS for 27 years. Peaked in 2012

Portugal has been "sending" SMS for 27 years.  Peaked in 2012

The text messaging service, launched in 1995 in Portugal, peaked in 2012 with over 27 million SMS sent, and according to ANACOM data, that number has dropped to 10 million in 2021.

The world’s first SMS (Short Message Service) was sent 30 years ago, on December 3, 1992, by Briton Neil Papworth, a telecommunications engineer at Sema Group Telecoms, in the United Kingdom.

A Merry Christmas message was sent from Neil Papworth’s computer to Vodafone’s Richard Jarvis’ Orbitel 901 mobile phone.

The historic moment reached a new level in December 2021 when the first 15-character SMS was auctioned off as NFTs (“Non Fungible Tokens” or “Non Fungible Token”) for 107,000 euros during an event hosted by Aguttes in France. .

In Portugal, the messaging service was launched in October 1995 when TMN (currently MEO) and Telecel (currently Vodafone) were in the mobile carrier market, according to data sent to the Lusa Autoridade Nacional de Comunicações (ANACOM) agency.

In October 1995, Telecel first launched the feature for contract services that were not prepaid, a small percentage of the customer base, said Lusa Nuno Taveira, a former product manager for SMS and “messaging” at Vodafone.

One of the turning points in the development of SMS was in February 2000, when an agreement was signed between the three existing operators (after the introduction of Optimus in 1998, now NOS) allowing users to communicate between different networks, the regulator cites.

The first data available in ANACOM refers precisely to the year 2000, when the number of SMS reached 550 million, i.e. about seven SMS per active user per month.

The peak of SMS traffic was reached in 2012, when each effective user sent 180 messages per month, for a total of 27,860,126 messages.

However, according to ANACOM, this number is decreasing. In 2021, 68 SMS were sent per effective user per month (-62% compared to 2012), for a total of 10,729,392.

Another turning point for SMS in Portugal was the introduction of prepaid services, which allowed mobile services to become mainstream, said Lusa Teresa Salema, president of Fundação Portuguesa das Comunicações.

“We must remember that the mobile network first grows in higher segments. It was only after 1995, with the introduction of prepaid services, that we had a greater mass, and at that time, text messages also appeared with greater intensity and reached an absolute level. records,” he said, noting the arrival of the “famous MIMO developed at the time by Portugal Telecom in the laboratories of Aveiro.”

There are now more popular alternative ways to send messages, “instant messaging” such as Whatsapp or Messenger apps available for “smartphones” that combine text with the ability to send images, sounds, documents or popular GIFs.

In 30 years, SMS has had a peak in usage and is now in decline. But its use in advertising and marketing, from a security point of view, as an authentication factor or to create a particular spelling, such as using “k” to mean “it”, is a legacy that continues today.

However, the President of the Portuguese Communications Foundation stated that the technology currently available to the public involves the integration of several factors.

“There are three things that are needed because, in addition to the equipment, access to networks with the bandwidth and speed that we currently have with optical fiber or 5G is needed. And “cloud” (cloud). These are three things that we need to have the services that we have now,” he analyzed.

Teresa Salema, who worked at the Companhia Portuguesa Rádio Marconi in the early 1990s and has a three-decade career in the sector, also defended that technology exists to “improve the quality of life as well as the health of the planet.” .

While there are better ways to send messages these days, Teresa Salema points out that all technology eventually finds its place.

“The fixed network has its own space. And SMS also has its place,” he stressed.

In the case of SMS, its popularity and widespread use via mobile phones ended with another service that had gained relevance earlier: pagers or the “beep-beep” service, he recalled.

“Today, in our museum, we only have what a written message of this type looked like. It was almost like a telegram, so it was even shorter than an SMS.”

In addition, the Fundação Portuguesa das Comunicações, now 25 years old, has a dual mission of “preserving and displaying the entire heritage of the communications sector in Portugal” through the Communications Museum in Lisbon.

Teresa Salema said the history of communication is “much longer” compared to the decade in which SMS was born, and in Portugal it is “five centuries ago, in 1520, with the creation of the postal service”.

“At one time, King D. Manuel created a postal service specifically to support the Portuguese maritime expansion. Because, as is obvious, any economic development is based on a communication network,” he stressed.

The Museum of Communications now has an exhibition to mark its 25th anniversary where you can “touch and experience objects” of old and working technologies such as the typewriter, fax, telex and some GSM equipment, including Nokia co the famous game “Snake”.
