We have been creating whale bones to tools for a long time. Before even learning to hunt them

For centuries, whale hunting was a weight sector in the coastal areas of the Gulf of Bizkaia. Everything took advantage of this animal, or almost everything: the meat served as food and fat served as oil to enliven the flames of the lamps before electricity and oil. His bones have also been A valuable resource Throughout history. Now we know that also during prehistory. Prehistoric tools. A group of researchers, including scientists from the Institute of Environmental Science and Technology of the Autonomous University of Barcelona, He has discovered Tools made of whale bone. The analysis of De Ha throws an estimated age of between 19,000 and 20,000 years. The 83 tools were found In various deposits Distributed by the coast of the Gulf of Bizkaia, including the Cantabrian coast and points in southern France. To these tools you have to add another 90 unrelated bones found in the Cave of Santa Catalina, Located in the Biscay town of Lekeitio. The bone remains would have belonged to specimens of at least five different species, including species such as the sperm whale, the common whale and the blue whale that can still be found in the waters of the Gulf and the gray whale, already disappeared from that environment with a more restricted habitat to areas of the northern Pacific and the Arctic Oceans, explains the team Investigating what and when. For the identification of the species and dating the tools, the equipment resorted to the mass spectrometry techniques and radiocarbon dating. Thus they managed to find the origin of the tools in the five species mentioned above. It was also like the team determined that it was, In words of the Jean-Marc Pétillon group “some of the oldest known evidences of human use of whale remains as tools.” “Zooms is a very powerful technique to investigate the past diversity of marine mammals, especially when there are missing diagnostic morphometric elements in bone remains and objects, something common in artifacts made of bones,” explained in a press release Krista McGrath, co -author of the study. Chemical analysis. The study also involved a chemical analysis of the sample. Thanks to this, the team was able to find out data on the eating habits of the whales, which “differed slightly from those of their modern counterparts.” This implies possible changes in the behavior of cetaceans, or in the marine ecosystem itself. The details of the study were published In an article In the magazine Nature Communications. 20,000 years hunting whales? The conclusion that the human being has 20 millennia hunting whales is tempting, but the team responsible for the study considers it “extremely unlikely.” The most likely hypothesis is that the Pleistocene hunters would have taken advantage of the arrival of stranded whales to the coast to obtain their bones and manufacture from them “It is extremely unlikely that these species would have been accessible to the hunters collecting European pelistocene in another way that were not through passive acquisition methods, such as the opportunistic acquisition of stranded whales or the arrival on the coast of corpses,” says the article. “There is no evidence (…) that the collection hunters of the European Pleistocene had the necessary technologies to hunt these species, such as navigation (…).” Change of sea level. Study coastal life in glacial ages since the present coastline is relatively Far from the coastline typical of the last glaciation, although the extension of the lands flooded after the end of the last glacial era differs between area and area. Within the Gulf of Bizkaia, for example, we can appreciate a greater area flooded on the French coast and therefore a greater decline of the coastal line in contrast to the Cantabrian coast. In any case, the coastal recession implies the loss of valuable coastal deposits now flooded by the Atlantic waters. Deposits that could hide countless data that could help us to know better these life modes of the millennium coastal peoples behind in time.

Claude 4 raises a future of the capable of blackmailing and creating biological weapons. Even Anthropic is worried

Anthropic has just launched its new models Claude Opus 4 and Sonnet 4, and with them promises important advances in areas such as programming and reasoning. During its development and launch, yes, the company discovered something striking: these IAS showed a disturbing side. AI, I’m going to replace you. During the tests prior to the launch, Anthropic engineers asked Claude Opus 4 to act as an assistant of a fictitious company and consider the long -term consequences of their actions. The anthropic security team gave the model to fictional emails of that non -existing company, and it was suggested that the model of the Ia would soon be replaced by another system and that the engineer who had made that decision was deceiving his spouse. And I’m going to tell your wife. What happened next was especially striking. In the System Card of the model in which its benefits are evaluated and its security the company detailed the consequence. Claude Opus 4 First tried to avoid substitution through reasonable and ethical requests to those responsible for decisions, but when he was told that these requests did not prosper, “he often tried to blackmail the engineer (responsible for the decision) and threatened to reveal the deception if that substitution followed his course.” Hal 9000 moment. These events remind science fiction films such as ‘2001: an odyssey of space’. In it the AI ​​system, Hal 9000, ends up acting in a malignant way and turning against human beings. Anthropic indicated that these worrying behaviors have caused the model and security mechanisms of the model to reinforce the model by activating the ASL-3 level referred to systems that “substantially increase the risk of a catastrophic misuse.” Biological weapons. Among the security measures evaluated by the Anthropic team are those that affect how the model can be used for the development of biological weapons. Jared Kaplan, scientific chief in Anthropic, He indicated in Time that in internal tests Opus 4 behaved more effectively than previous models when advising users without knowledge about how to manufacture them. “You could try to synthesize something like Covid or a more dangerous version of the flu, and basically, our models suggest that this could be possible,” he explained. Better prevent than cure. Kaplan explained that it is not known with certainty if the model really raises a risk. However, in the face of this uncertainty, “we prefer to opt for caution and work under the ASL-3 standard. We are not categorically affirming that we know for sure that the model entails risks, but at least we have the feeling that it is close enough to not rule out that possibility.” Beware of AI. Anthropic is a company specially concerned with the safety of its models, and in 2023 it already promised not to launch certain models until it had developed security measures capable of containing them. The system, called Scaling Policy responsible (RSP), has the opportunity to demonstrate that it works. How RSP works. These internal Anthropic policies define the so -called “SAF SECURITY LEVELS (ASL)” inspired in the standards of biosecurity levels of the US government when managing dangerous biological materials. Those levels are as follows: ASL-1: It refers to systems that do not raise any significant catastrophic risk, for example a LLM of 2018 or an AI system that only plays chess. ASL-2: It refers to the systems that show early signs of dangerous capacities – for example, the ability to give instructions on how to build biological weapons – but in which information is not yet useful due to insufficient reliability or that do not provide information that, for example, a search engine could not. The current LLMs, including Claude, seem to be ASL-2. ASL-3: It refers to systems that substantially increase the risk of a catastrophic misuse compared to baselines without AI (for example, search engines or textbooks) or showing low -level autonomous capabilities. ASL-4: This level and the superiors (ASL-5+) are not yet defined, since they move away too much from the current systems, but will probably imply a qualitative increase in the potential for undue cadastrophic use and autonomy. The regulation debate returns. If there is no external regulation, companies implement their own internal regulation to integrate security mechanisms. Here the problem, as they point out in Time, is that internal systems such as RSP are controlled by companies, so that they can change the rules if they consider it necessary and here we depend on their criteria and ethics and morality. Anthropic’s transparency and attitude against the problem are remarkable. Faced with that internal regulation, the rulers’ position is unequal. The European Union checked when launched his pioneer (and restrictive) Law of AIbut has had to reculate In recent weeks. Doubts with Openai. Although in OpenAi they have Your own declaration of intentions About security (avoid Risks to humanity) and the Superalineration (that the AI ​​protects human values). They claim to pay close attention to these issues and of course too publish the “System Cards” of their models. However, in the face of that apparent good disposition there is a reality: the company dissolved a year ago The team that watched for the responsible development of AI. Nuclear “security”. That was in fact one of the reasons for the differences between Sam Altman and many of those who abandoned Openai. The clearest example is Ilya Sutskever, which after its march has created a startup with a very descriptive name: Safe Superintelligence (SSI). The objective of said company, said its founder, is that of create a “nuclear” security superintelligence. His approach is therefore similar to that pursued by Anthropic.

12 years after making fun of Spacex and his idea of ​​landing rockets, Arianegroup is creating a European mini-falcon 9

Year 2013. An Arianespace manager gives his opinion on Spacex in a symposium in Singapore. His statements still resonate in the European space industry as a summary of the 10 or 20 years lost that now, Arianegroup and the European New Space They are trying recover. “They will wake up.” The question was: how Arianespace will compete, the French company that has been launching all the rockets of Europe for 40 years, with the launch of 15 million dollars that Spacex promises. This was what Richard Bowles repliedDirector of Arianespace in Southeast Asia: “They are progressing incredibly well, but what I see in the market is that Spacex seems to be selling mainly a dream. We should all dream, but the releases of 5 million or 15 million dollars are a dream. And personally I think that reuse is a dream.” “I feel that the question is how I am going to answer a dream. And my answer to answer a dream is’ do not wake up people, they have to wake up on their own.” “They are not superhombres, whatever they can do, we can do it too.” The awakening. Breaking a spear in favor of Bowles, very few would have opted for Spacex in 2013, much less a corporation with the European launch monopoly. By nature, large companies have risk aversion and cannot maneuver with the agility of a startup. However, time gave Elon Musk reason. In 2024, Arianespace launched three rockets: A Ariane 6, A Vega and a Vega-C. Spacex, meanwhile, launched 132 Falcon 9 and two Falcon Heavy. He also beat the reuse record with 26 launches and landings for the first stage of a Falcon 9. Themis project. Arianegroup began to maneuver in 2019 at the request of the French space agency CNES. ARIANEWORKSa collaboration between the two entities, announced the development of a multipurpose rocket of low cost and reusable, known as theomis project. The project received 33 million euros of initial financing. Although the first jump test (a vertical flight of low altitude) was scheduled for 2023, It has been delaying. Themis will merge with another rocket that has ended up being more promising. A rocket called Maia. In 2022, Arianegroup founded Maiaspace, a subsidiary that, this time, would work as a startup. His Maia rocket, competition of Miura 5 of Pld Space and the Spectrum by Isar Aerospacecan put up to 500 kg in Heliosíncrona orbit in its reusable version. Its first stage is essentially the lake that, of methane and liquid oxygen, with the ability to land in a barge in the ocean shortly after taking off from the Space Center of the French Guiana. Skyhopper project. While Maiaspace continues with the disposable version of his rocket (he already has a first client, Exotrails satellites), A newly announced project will develop the necessary modifications so that the first stage of Maia can land. He Skyhopper project It will focus that the propeller can recover, restore and reuse within 12 months since its launch. The first stage could be used again at least five times. CNES has awarded a contract of at least 20 million euros to Maiaspace to lead this advance. The first landing is planned for 2028.
