An editorial published in a journal noted that remote surgery and types of videoconferencing for sharing expertise have been and could be used to support doctors in Ukraine. A forum contribution analyzed Russian users' reactions to the Bucha massacre on social media – on nationalist Telegram channels. Computer science and technology was also used to defend against the 2022 Russian invasion such as with military technology, to document and communicate war events including via facial recognition of dead Russian soldiers and Russian war crimes, and for aggregated information about support opportunities for Ukrainian scientists.
  • Researchers demonstrated an MRI-ML-based approach that can diagnose early Alzheimer's disease and may help identify unknown related changes in the brain.
  • A study explored the efficacy of GitHub Sponsors, launched in 2019, in terms of supporting FOSS-efforts and the sponsors' intentions as well as the motivation of sponsors and various quantitative and qualitative analyses relevant to this approach of FOSS-funding.
  • Progress in climate change mitigation living review-like works:
The living document-like aggregation, assessment, integration and review website Project Drawdown added 11 new CCM solutions to its organized set of mitigation techniques. The website's modeling framework was used in a study document to show that metal recycling has significant potential for CCM. A revised or updated version, using computer models, of a major worldwide 100% renewable energy proposed plan and model was published.

  • Thomas Metzinger, a German philosopher of cognitive science and applied ethics, called for a "global moratorium on synthetic phenomenology" which, "until 2050", precautionarily bans "all research that directly aims at or knowingly risks the emergence of artificial consciousness on post-biotic carrier systems" – and could be gradually refined. The paper does not describe mechanisms of global enforcement of such proposed regulations which do not consider biotic or semi-biotic systems and aims to limit suffering risks.
  • – A new global food emissions database indicated that the current food systems are responsible for one third of the global anthropogenic greenhouse gas emissions.
  • – In a static proprietary article that appeared in and was co-reviewed by a scientific journal, authenticated scientists analyzed data from multiple public databases to create a regional representation of levels of deforestation induced by nations' recent, largely unmodulated, trade-, production- and consumption-patterns.
  • A study found that carbon emissions from Bitcoin mining in China – where a majority of the proof-of-work algorithm that generates current economic value is computed, largely fueled by nonrenewable sources – had accelerated rapidly and would soon exceed total annual emissions of countries like Italy, interfering with climate change mitigation commitments. Available under .
  • Neuralink revealed a male macaque with chips embedded on each side of its brain, playing a mind-controlled version of Pong. While similar technology has been demonstrated for decades, and wireless implants have existed for years, some observers noted that the organization increased the number of implanted electrodes that are read wirelessly.
  • Scientists reviewed materials strategies for organic neuromorphic devices, suggesting that "their biocompatibility and mechanical conformability give them an advantage for creating adaptive biointerfaces, brain-machine interfaces, and biology-inspired prosthetics".
  • Researchers published the first in-depth study of Web browser tab interfaces. They found that many people struggle with tab overload and conducted surveys and interviews about people's tab use. Thereby they formalized pressures for closing tabs and for keeping tabs open. The authors then developed related UI design considerations which could enable better tools and changes to the code of Web browsers – like Firefox – that allow knowledge workers and other users to better manage their tabs.
  • Operation of the U.S. Colonial Pipeline was interrupted by a ransomware cyber attack.
  • A new record for the smallest single-chip system was achieved, occupying a total volume of less than 0.1 mm3.
  • Scientists demonstrated the first brain–computer interface that decodes neural signals for handwriting. The character output speed of a patient with a paralyzed hand was up to 90 characters per minute – more than double the previous record. Each letter is associated with a highly distinctive pattern of activity in the brain, making it relatively easy for the algorithm to distinguish them.
  • Archivists initiated a rescue mission to secure enduring access to humanity's largest public library of scientific articles, Sci-Hub, due to the site's increased legal troubles, using Web and BitTorrent technologies.
  • Google demonstrated a research project called LaMDA, an automatic language generation system designed to sustain a conversation with a person on any topic.
  • The most comprehensive 3D map of the human brain – of a millionth of a brain and requiring 1.4 petabytes of storage space – was published.
  • El Salvador passed the Bitcoin Law, making it the first country to give cryptocurrency and bitcoin a status of legal tender. The law was passed by the Legislative Assembly of El Salvador on June 8, 2021, giving the cryptocurrency bitcoin the status of legal tender within El Salvador after September 7, 2021. It was proposed by President Nayib Bukele. The text of the law states that "the purpose of this law is to regulate bitcoin as unrestricted legal tender with liberating power, unlimited in any transaction, and to any title that public or private natural or legal persons require carrying out".
  • GitHub Copilot, a programmer assistant AI, was released. Later FOSS variants of the tool included FauxPilot.
  • In the debate regarding the cognitive impacts of smartphones and digital technology, a group reported that, contrary to widespread belief, scientific evidence does not show that these technologies harm biological cognitive abilities and that they instead change predominant ways of cognition – such as a reduced need to remember facts or conduct mathematical calculations by pen and paper outside contemporary schools. However, some activities – like reading novels – that require long attention-spans and don't feature ongoing rewarding stimulation may become more challenging in general.
  • Open 3D Engine – a game engine that is free and open source software and has Linux support – was released.
  • Researchers used a brain–computer interface to enable a man who was paralyzed since 2003 to produce comprehensible words and sentences by decoding signals from electrodes in the speech areas of his brain.
  • Japan achieved a new world record Internet speed: 319 Tbit/s over ~3000 km which, albeit not being the fastest speed overall, beats the previous record of 178 Tbit/s.
  • Scientists reported that worldwide adolescent loneliness and depression increased substantially after 2012 and that loneliness in contemporary schools appears to be associated with smartphone access and Internet use.
  • DeepMind announced that its AlphaFold AI had structure prediction|predicted] the structures of over 350,000 proteins, including 98.5% of the ~20,000 proteins in the human body. The 3D data along with their degrees of confidence for accuracy was made freely available with a database, doubling the previous number of protein structures in the public domain.
  • Scientists published the first complete neuron-level-resolution 3D map of a monkey brain which they scanned within 100 hours.
  • A researcher reported that solar superstorms would cause large-scale global months-long Internet outages. She described potential mitigation measures and exceptions – such as user-powered mesh networks and related peer-to-peer applications – and the robustness of the current Internet infrastructure.
  • Scientists concluded that personal carbon allowances could be a component of climate change mitigation. They found that the economic recovery from COVID-19 and novel digital technology capacities open a window of opportunity for first implementations. PCAs would consist of – e.g. monetary – credit-feedbacks and decreasing default levels of per capita emissions concessions. The researchers found that recent advances in machine learning technology and "smarter home and transport options make it possible to easily track and manage a large share of individuals' emissions" and that feedback effective in engaging individuals to reduce their energy-related emissions and relevant new personalized apps could be designed. Issues may include privacy, evaluating emissions from individuals co-running multinational companies and the availability and prices of products and services.
  • Cerebras announced a new hardware and software platform that can support AI models of 120 trillion parameters, enabling neural networks greater than the equivalent number of human brain synapses.
  • Pathogen researchers reported the development of machine learning models for genome-based early detection and prioritization of high-risk potential zoonotic viruses in animals prior to spillover to humans. They concluded that their tool could be used for virus surveillance for pandemic prevention via measures of "early investigation and outbreak preparedness" and would have been capable of predicting SARS-CoV-2 as a high-risk strain.
  • A loss of public IP routes to the Facebook DNS servers due to malfunctioning capacity-assessment code, routinely triggered after configuration changes of routers of the company's data centers, resulted in stoppage of BGP routing information broadcasts caused the 2021 Facebook outage.
  • A study of data traffic by popular smartphones running variants of the Android software found substantial by-default data collection and sharing with no opt-out and implications for users' privacy, control and security.
  • Media outlets reported novel technologies for virtual try-ons of clothes for more sustainable fashion and improved online shopping, which increased relative to shopping at local shops that store clothes Impact of the [COVID-19 pandemic on the fashion industry|due to the COVID-19 pandemic].
  • A method of DNA data storage with 100 times the density of previous techniques was announced.
  • Scientists demonstrated that grown brain cells integrated into digital systems can carry out goal-directed tasks with performance-scores. In particular, playing a simulated Pong which the cells learned to play faster than known machine intelligence systems, albeit to a lower skill-level than both AI and humans, was reported. Moreover, the study suggested it provides the "first empirical evidence" of information-processing capacity differences between neurons from different species.
  • Researchers reported the development of organic low-power neuromorphic electronics which they built into a robot, enabling it to learn sensorimotorically within the real world, rather than via simulations like in the study above. For the chip, polymers were used and coated with an ion-rich gel to enable the material to carry an electric charge like real neurons.
  • Researchers reported the development of a system of machine learning and hyperspectral camera that can distinguish between 12 different types of plastics such as PET and PP for automated separation of waste of, as of 2020, highly unstandardized plastics products and packaging.
  • A scientific review summarized research and data about telemedicine. Its results indicated that, in general, outcomes of such ICT-use are as good as in-person care with health care use staying similar.
  • The Log4Shell security vulnerability in a Java logging framework was publicly disclosed two weeks after its discovery. Because of the ubiquity of the affected software, experts have described it as a most serious computer vulnerability. In a high-level meeting, the importance of security maintenance of open-source software – often also carried out largely by few volunteers – to national security was clarified.
  • Researchers reported the development of a database and analysis tool about perovskite solar cells which systematically integrates over 15,000 publications, in particular device-data about over 42,400 of such photovoltaic devices. Authors described the site – which requires signing up to access the data and uses software that is partly open source but to date not free software – as a participative "Wikipedia for perovskite solar cell research" and suggest that extensively capturing the progress of an entire field including interactive data exploration functionalities could also be applicable to many fields in materials science, engineering and biosciences.
  • A third main convergent graphical shell and UI framework, based on KDE/Kirigami, for the Linux operating system on smartphones, desktops and other devices, was released.
