Gold-enhanced TiO₂ catalyst enables efficient and selective flow synthesis of propane from methane

Methane (CH₄), the colorless and odorless gas that makes up most natural gas on Earth, has so far been converted into useful fuels and chemicals via energy-intensive processes that need to be carried out at high temperatures. Some energy researchers, however, have been exploring the possibility of transforming this gas into useful hydrocarbons and chemicals via photocatalysis.

Photocatalysis is a process through which the energy contained in light, typically solar energy, activates a material known as a “catalyst,” driving desired chemical reactions. Converting CH₄ into specific fuels or chemicals via photocatalysis instead of conventional methods that rely on the burning of fossil fuels could be highly advantageous, as it could contribute to the reduction of greenhouse gas emissions.

Researchers at Hebei University and other institutes in China recently introduced a new photocatalysis-driven approach to convert CH₄ into propane (C₃H₈), a hydrocarbon that is easier to use in real-world settings, as it becomes liquid at specific pressures, which facilitates its storage and transport.

Astronomers capture breathtaking first look at a planet being born

WISPIT2b, a gas giant forming around a young Sun-like star, has been directly imaged for the first time inside a spectacular multiringed disk. Still glowing and actively accreting gas, the planet offers a unique opportunity to study planetary birth and evolution.

An international team of astronomers, co-led by researchers at University of Galway, has made the unexpected discovery of a new planet.

Detected at an early stage of formation around a young analog of our own Sun, the planet is estimated to be about 5 million years-old and most likely a gas giant of similar size to Jupiter.

Could We Accidentally Destroy the Universe?

What if the end of everything came not from cosmic fate, but from us? This episode examines the physics, probability, and peril of experiments that could, in theory, unravel the universe.

EBITDA vs Milestones: The Real Unlocks in Elon’s 2025 Comp Plan

Questions to inspire discussion.

🤖 Q: How will Tesla’s CyberCab production differ from traditional assembly? A: CyberCab production will be unboxed with Tesla bots, not humans, using four major pieces that snap together like Lego, making it faster and more efficient.

🚕 Q: What is Tesla’s approach to building its robotaxi network? A: Tesla plans an Airbnb-style network using existing cars and fast-built CyberCabs to reach 1 million robotaxis and $50 billion EBITDA within 1–2 years after launch.

🌆 Q: How might the robotaxi network impact urban landscapes? A: The network could make transportation cheaper for everyone, especially older people and non-drivers, potentially transforming cityscapes and encouraging suburban expansion.

Financial Targets.

💰 Q: What are the market cap milestones in Tesla’s compensation plan? A: The plan requires reaching a $2 trillion market cap initially, with subsequent milestones up to $8.5 trillion, requiring sequential achievement.

Ultrasound helmet enables deep brain stimulation in people without surgery

An ultrasound device that can precisely stimulate areas deep in the brain without surgery has been developed by researchers from UCL and the University of Oxford, opening up new possibilities for neurological research and treatment of disorders such as Parkinson’s disease.

A paper describing this work appears in Nature Communications.

Scientists have long been looking for a way to modulate brain function, which could improve our understanding of how the brain works and help to treat , using non-invasive methods that don’t involve surgery. One technology that could help is transcranial ultrasound stimulation (TUS), which was recently discovered to be able to modulate the activity of neurons (the brain’s key communication cells) by delivering gentle mechanical pulses that influence how these cells send signals.
