Could Ukraine hold a presidential election right now? Will Europe use frozen Russian assets to fund war? How can Ukraine rebuild China ties? 'Ukraine is running out of men, money and time' Ukrainian President Volodymyr Zelenskyy said that a state of emergency was being declared for Ukraine's energy sector, after repeated Russian attacks destroyed electricity and heat infrastructure. Zelenskyy said he asked the government to review curfew restrictions during "this extremely cold weather".

President Trump signed a proclamation on Wednesday to impose a 25 percent tariff on a narrow list of foreign semiconductors, providing a way for the government to earn revenue off the sale of lucrative chips used in artificial intelligence. The tariff, which would take effect Thursday, is far more limited than what the president initially threatened. Last year, the administration began an investigation aimed at encouraging tech companies and chip makers to buy semiconductors made in America. But instead of approving sweeping tariffs that would affect the industry, Wednesday's announcement showed the administration has settled for narrower levies that allow it to take a cut of artificial intelligence chips sold to China. A document released by the White House said a 25 percent tariff would be put on A.I. chips made by companies like Nvidia and AMD that are imported into the United States and then re-exported to other countries. The tariff would not apply to semiconductors that are brought into the country to be used domestically in data centers or in products for American consumers, industry or the government.

The news is a blow for Thinking Machines Lab. Two narratives are already emerging about what happened. Thinking Machines cofounders Barret Zoph and Luke Metz are leaving the fledgling AI lab and rejoining OpenAI, the ChatGPT-maker announced on Thursday. OpenAI's CEO of applications, Fidji Simo, shared the news in a memo to staff Thursday afternoon. The news was first reported on X by technology reporter Kylie Robison, who wrote that Zoph was fired for "unethical conduct."

Elon Musk's AI model Grok will no longer be able to edit photos of real people to show them in revealing clothing, after widespread concern over sexualised AI deepfakes in countries including the UK and US. We have implemented technological measures to prevent the Grok account from allowing the editing of images of real people in revealing clothing such as bikinis. This restriction applies to all users, including paid subscribers, reads an announcement on X, which operates the Grok AI tool. The change was announced hours after California's top prosecutor said the state was probing the spread of sexualised AI deepfakes, including of children, generated by the AI model. The update expands measures that stop all users, including paid subscribers, editing images of real people in revealing outfits.

Zelensky declares state of emergency in Ukraine's energy sector Ukraine has declared a state of emergency in the country's energy sector, with particular focus on Kyiv, as ongoing Russian strikes continue to leave thousands of residents without power. The nation is in the midst of a particularly cold winter, with overnight temperatures in Kyiv dropping to around -20C. After a special cabinet meeting, President Volodymyr Zelensky said a round-the-clock task force would be set up to deal with the damaging consequences of Russian airstrikes and worsening weather conditions. He accused Moscow of deliberately exploiting the harsh, sub-zero temperatures to target critical infrastructure, including energy distribution facilities. In recent weeks, Kyiv has been particularly affected by Russian attacks, leaving thousands of homes without regular power, heating or running water.

Structure-based and ligand-based computational drug design have traditionally relied on disjoint data sources and modeling assumptions, limiting their joint use at scale. In this work, we introduce Contrastive Geometric Learning for Unified Computational Drug Design (ConGLUDe), a single contrastive geometric model that unifies structure- and ligand-based training. ConGLUDe couples a geometric protein encoder that produces whole-protein representations and implicit embeddings of predicted binding sites with a fast ligand encoder, removing the need for pre-defined pockets. By aligning ligands with both global protein representations and multiple candidate binding sites through contrastive learning, ConGLUDe supports ligand-conditioned pocket prediction in addition to virtual screening and target fishing, while being trained jointly on protein-ligand complexes and large-scale bioactivity data. Across diverse benchmarks, ConGLUDe achieves state-of-the-art zero-shot virtual screening performance in settings where no binding pocket information is provided as input, substantially outperforms existing methods on a challenging target fishing task, and demonstrates competitive ligand-conditioned pocket selection. These results highlight the advantages of unified structure-ligand training and position ConGLUDe as a step toward general-purpose foundation models for drug discovery.

Dr Jessica Rose, a Canadian researcher and expert in immunology from Memorial University of Newfoundland, said her 2021 study exposing a connection between Covid vaccines and myocarditis was mysteriously withdrawn just three weeks after it was published by the journal Current Problems in Cardiology without explanation. Myocarditis is a dangerous inflammation of the heart that can cause chest pain, shortness of breath, fatigue, irregular heartbeat, and swelling in the legs. In severe cases, it can lead to heart failure, blood clots, stroke, or sudden death. Using information from a government-run database to track vaccine side effects, Rose found a significant increase in heart damage weeks after people received the Covid vaccine.

Apple's Siri AI will be powered by Gemini The company is also blocking image generation entirely from non-subscribers. XAI logo dislpayed on a screen and Grok account on X displayed on a phone screen are seen in this illustration photo taken in London, Great Britain on July 9, 2025. X says it is changing its policies around Grok's image-editing abilities following a multi-week outcry over the chatbot repeatedly being accused of generating sexualized images of children and nonconsensual nudity. In an update shared from the @Safety account on X, the company said it has "implemented technological measures to prevent the Grok account from allowing the editing of images of real people in revealing clothing such as bikinis." The new safeguards, according to X, will apply to all users regardless of whether they pay for Grok.

The killing of George Floyd in 2020 prompted a wave of statements from tech companies and CEOs. Today, pushback against ICE is largely coming from employees, not executives. Since Donald Trump returned to the White House last January, the biggest names in tech have mostly fallen in line with the new regime, attending dinners with officials, heaping praise upon the administration, presenting the president with lavish gifts, and pleading for Trump's permission to sell their products to China . It's been mostly business as usual for Silicon Valley over the past year, even as the administration ignored a wide range of constitutional norms and attempted to slap arbitrary fees on everything from chip exports to worker visas for high-skilled immigrants employed by tech firms. But after an ICE agent shot and killed an unarmed US citizen, Renee Nicole Good, in broad daylight in Minneapolis last week, a number of tech leaders have begun publicly speaking out about the Trump administration's tactics.

Police say at least 25 kids used e-bikes and scooters to evade arrest and intimidate drivers. Breakthroughs, discoveries, and DIY tips sent six days a week. Australian police are cracking down on groups of unruly teenagers who they say are using deceptively speedy e-bikes and scooters to engage in "antisocial riding behavior." Their solution: confiscate the popular micromobility devices and crush them. The roundup, dubbed Operation Moorhead, began last week in the suburbs of Perth in southwestern Australia.
