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 neurological diseases, 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.
Researchers uncover critical genetic drivers of the gut’s ‘nervous system’ development
Vanderbilt researchers, including those from the Vanderbilt Brain Institute, have made significant strides in understanding how the enteric nervous system—sometimes called the “brain” of the gut—forms and functions.
In a study published in Cellular and Molecular Gastroenterology and Hepatology, the lab of principal investigator, Michelle Southard-Smith, sheds light on how the SOX10 protein contributes to the development of gut cells that play a role in gastrointestinal motility, or how food moves through the digestive system.
The paper is titled “Single Cell Profiling in the Sox10Dom Hirschsprung Mouse Implicates Hox genes in Enteric Neuron Trajectory Allocation.”
A fiber optic cable spied on Greenland’s glaciers. It found an alarming problem
One of the buzziest technologies in modern science may be running right under your feet. Fiber optic cables bring you the internet as data-rich pulses of light, but they also detect signals from the surrounding environment: Researchers can analyze the light that’s scattered when a volcanic eruption or tsunami jostles the wiring. Known as distributed acoustic sensing, or DAS, the technique is so sensitive that it can track your footsteps as you walk over a cable, and may one day even warn you of an impending earthquake.
Now, researchers have laid a fiber optic cable on the seafloor near a glacier in Greenland, revealing in unprecedented detail what happens during a calving event, when chunks of ice drop into the ocean. That, in turn, could help solve a long-standing conundrum and better understand the hidden processes driving the rapid deterioration of the island’s ice sheet, which would add 23 feet to sea levels if it disappeared.
Even before humans started changing the climate, Greenland’s glaciers were calving naturally. The island is covered in glaciers that slowly flow toward the ocean, breaking into icebergs that float out to sea. When temperatures were lower, the ice sheet was also readily regenerating as snow fell.
