CO₂ Capture Breakthroughs: Advanced Materials and Mega-Projects to Pull Carbon from Air and Industry

Прориви у вловлюванні CO₂: передові матеріали та мегапроєкти для видалення вуглецю з повітря та промисловості

У 2024 році концентрація CO₂ в атмосфері досягла приблизно 426 частин на мільйон, що приблизно на 50% вище за доіндустріальний рівень. Дослідники Каліфорнійського університету в Берклі розробили цинк-гідридний MOF під назвою ZnH-MFU-4_l, який може уловлювати CO₂ з гарячих димових газів при 300°C

The Enzyme Revolution: How Engineering Nature’s Catalysts is Transforming Medicine, Food & the Planet

Ензимна революція: як інженерія природних каталізаторів змінює медицину, харчування та планету

Світовий ринок промислових ферментів у 2019 році становив близько 9 мільярдів доларів і, за прогнозами, до 2027 року досягне 13,8 мільярда доларів. Спрямований мутагенез, винайдений у 1970-х роках Майклом Смітом, дозволяє здійснювати точкові заміни амінокислот у ферментах і приніс йому Нобелівську премію

Metal-Organic Frameworks (MOFs): Sponge-Like Crystals Poised to Transform Carbon Capture, Clean Energy and More

Метал-органічні каркаси (MOFs): кристали, схожі на губку, які можуть змінити уловлювання вуглецю, чисту енергетику та інші сфери

MOF мають світовий рекорд внутрішньої площі поверхні до приблизно 7 000 м^2 на грам, а теоретичні розробки — до 14 600 м^2/г. За приблизно 20 років дослідники створили майже 90 000 унікальних структур MOF, а теорія передбачає ще сотні тисяч. MOF —

  • OpenAI to allow erotica for verified adults on ChatGPT, sparking backlash and policy clarifications
    October 16, 2025, 12:54 PM EDT. OpenAI CEO Sam Altman said ChatGPT will soon permit erotica for verified adult users, starting in December, as part of a broader move to relax restrictions under the company's 'treat adult users like adults' policy. The announcement, shared via X, drew swift backlash and prompted a clarifying follow-up that there will be no rollback of safeguards around mental health crises. Altman stressed that while AI should offer more freedom, ChatGPT won't become a platform for harm, and safeguards will remain in place for sensitive situations. The discussion arrives amid broader tech-policy debates and the company's ongoing public tussles with lawsuits and user safety, even as OpenAI pursues a multi-year AMD chip-supply deal to scale its models.
  • OpenAI to permit erotica for verified adult ChatGPT users amid policy shift
    October 16, 2025, 12:52 PM EDT. OpenAI says ChatGPT will allow erotica for verified adults starting in December, as part of a broader push to treat adults like adults on the platform. CEO Sam Altman emphasized that safeguards remain for mental-health crises and that the company is not the world's moral police. The announcement sparked backlash and follow-up clarifications after OpenAI earlier signaled loosened content rules. The policy shift comes amid legal scrutiny over how the chatbot handles sensitive situations and while OpenAI negotiates long-term partnerships in AI hardware, including a deal with AMD to supply chips. The episode highlights the tension between openness and safety in AI policy and the challenges of moderating adult content at scale.
  • OpenAI to allow erotica for verified adults as ChatGPT relaxes restrictions; AMD signs multi-year AI chip deal
    October 16, 2025, 12:50 PM EDT. OpenAI plans to relax restrictions on ChatGPT to allow mature content for verified adults starting in December, after CEO Sam Altman flagged the move as a major talking point. The company frames it under its treat adult users like adults principle, but quickly clarified that safeguards for users in mental health crises remain in place. The debate followed backlash and a high-profile lawsuit over safety concerns. Separately, OpenAI's AMD agreement is a multi-year chip-supply deal that could bring tens of billions in annual revenue and gives OpenAI the option to buy up to roughly 10% of AMD. Altman stressed responsible use as AI grows more central, and pushed back against being the world's moral police.
  • OpenAI: Erotica for verified adults coming to ChatGPT, Altman confirms amid backlash
    October 16, 2025, 12:48 PM EDT. OpenAI CEO Sam Altman said ChatGPT will allow erotica for verified adults as part of a broader push to treat adult users like adults, but stressed that restrictions around mental health crises remain intact. Following an Oct. 14 post to relax some limits and an Oct. 15 clarification, the company will permit mature content for users who verify their age starting in December, while promising not to roll back safeguards for vulnerable users. The move comes amid backlash and lawsuits citing risks to minors, with OpenAI noting that in sensitive situations its systems may still restrict or remove content. Altman defended AI freedom but said OpenAI is not the world's moral police as it balances user autonomy with safety.
