JUST IN: Harvard scientists detect radio signals directly from a planet outside our solar system for the first time, located 64 light-years from Earth.
Readers added context they thought people might want to know
The detected signals are natural auroral radio emissions from β Pictoris b's magnetic field, not evidence of intelligent life or technology.

Children who take music lessons develop a larger corpus callosum, the bridge between the two halves of the brain, and the change is permanent. A 2005 review in the Annals of the New York Academy of Sciences found that early music training produces structural brain changes that persist into adulthood, even if the person stops playing.
The review was led by Gottfried Schlaug at Harvard Medical School, one of the leading researchers on music and the brain. He found that children who started instrumental training before age seven had a significantly larger anterior corpus callosum than non-musicians, and the size difference was still visible in adults who had not touched an instrument in years.
The corpus callosum carries signals between the left and right hemispheres. A larger one means faster, richer communication between the two sides, and the effect shows up in tasks that have nothing to do with music: spatial reasoning, verbal memory, and the ability to process multiple streams of information at once. The music built the highway, and the brain uses it for everything.
Schlaug also found that musicians had larger cerebellums, the region involved in timing and motor coordination, and more grey matter in the areas that process sound. The brain had physically reorganised itself around the demands of the instrument, and the reorganisation was visible on a scan.
The age window matters. Children who started before seven showed the largest changes. Children who started after ten showed smaller ones. Adults who took up an instrument for the first time showed the least structural change, though they still showed some. The brain is most willing to be rebuilt by music during the years when most parents are debating whether to sign their child up for lessons. pubmed.ncbi.nlm.nih.gov/1659…

There is something special about #CarFreeDay in Kigali.
For a few hours on a Sunday morning, the city slows down. We walk, run, bike, exercise, and bring the children out, to simply enjoy streets that feel a little quieter, on a sunny morning that asks nothing of us.
These moments are a kind transition, between one week and the next.
Just a little space in between, like a precious reset before we begin again.
Happy Sunday, Kigali. ☀️

Taxi driver in New York asked me if I knew Stefanos Tsitsipas.
I said, "We're very close."
He said, "Good. Tell him to stop taking bathroom breaks like he's searching for Narnia."
I pulled my hood up and pretended I was a tourist from Oslo.

“Today, connectivity is no longer the end goal. We are now transitioning to the era of data-driven growth. Artificial intelligence is the common denominator that will redefine healthcare, education and energy, among many other sectors. As a commission, our mission is to ensure this transformation does not widen existing divisions.
The task ahead of us is urgent, but we will face challenges. The objective isn’t just to have a conversation. It is to ensure everything we agree to do, gets translated into tangible and practical outcomes.” President Kagame
President Kagame joined fellow Co-Chair Marc Benioff and Vice-Chair Doreen Bogdan-Martin for a fireside chat marking the launch of the AI for Good Global Commission. He then chaired the Commission’s inaugural meeting alongside Marc Benioff and Doreen Bogdan-Martin.
The high-level initiative brings together 44 commissioners to identify practical ways to harness artificial intelligence to address some of the world’s most pressing challenges.

“Artificial intelligence has the power to transform lives and strengthen economies. Africa is well-positioned to contribute to the digital economy. By 2050, our continent will have the largest, fastest-growing workforce in the world. There are many success stories about what our young people are doing on the continent with artificial intelligence. We have to invest in them. It will be a win-win for everyone. The bottom line, is that for A.I. to serve humanity as a whole, we must get it right in Africa and everywhere else.” President Kagame | #AIforGood Global Summit 2026

“My advice is simple: do not waste your energy fighting those who insult you.
Put your energy into building, building yourselves, and building your country, so that insults and the people who make them become insignificant and have no impact on you.
Ignore them, and keep doing what you are supposed to do. That is what matters.” ~ HE @PaulKagame

You asked, we delivered. If you’re a U.S. Google user, you can now change your account username for tools like Gmail, Photos, Drive and more — while keeping your emails, data and account history. Here’s what to know:
1️⃣ You can choose any available @gmail.com username.
2️⃣ Your old username will become an alias, so you won’t lose access to it. You can still sign in and send and receive emails with both usernames. Plus, you can also revert to your old username.
3️⃣ You can choose a new username once a year — up to three times total.

We trained a new flood forecasting model designed to predict flash floods in urban areas up to 24 hours in advance.
To help address a flash floods data gap, we created Groundsource: a new AI methodology using Gemini to identify 2.6M+ historical events across 150+ countries.
We’re open-sourcing this dataset to advance global research, and urban flash flood forecasts are live now in Flood Hub to help communities stay safe.

🚨 JUST IN: A migratory bird just shattered world records — flying 8,425 miles (13,560 km) NON-STOP across the Pacific without landing once.
The bar-tailed godwit doesn’t stop to eat, drink, or sleep during its migration across the Pacific Ocean. Its journey from Alaska to Australia takes roughly 11 days of continuous flight, covering over 13,000 kilometers through storms, headwinds, and open ocean with zero land beneath it the entire time.
Before departure, it does something almost surgical to its own body. It shrinks its digestive organs down to almost nothing, converting the stomach, intestines, and liver into raw fuel. The bird essentially eats its own gut to make room for fat reserves that will power its wings for nearly two weeks straight.
The brain doesn’t fully sleep either. Half of it stays active while the other half rests, alternating in shifts mid-flight at altitude over the open Pacific. The godwit is simultaneously unconscious and navigating with magnetic field sensitivity that no human instrument in the 18th century could replicate.
What makes this genuinely staggering beyond the physical record is the navigational precision involved. The bird leaves Alaska and arrives in New Zealand with accuracy that would embarrass early GPS systems. It reads Earth’s magnetic field, atmospheric pressure gradients, star positions, and potentially quantum-level compass mechanisms inside its eye that literally let it see magnetic field lines overlaid on its visual field.
Evolution spent millions of years building an aerospace navigation system inside a 300 gram animal.
We spend billions engineering machines that do what this bird does on instinct, fat reserves, and half a sleeping brain.
The longest recorded non-stop flight by a commercial aircraft is around 20 hours.
This bird does 11 days.
Without a runway.

According to @SBakerMD (and I believe him) the guy (verified 81 yo) in this video started sprinting at 66. Super impressive!
PS: First person to comment on the indoor lighting slowing him down needs a MRI.
