Beyond playgrounds: How less structured city spaces can nurture children's creativity and independence
Children's play is essential for their cognitive, physical and social development. But in cities, spaces to play are usually separated, often literally fenced off, from the rest of urban life.
Japan launches a climate change monitoring satellite on mainstay H2A rocket's last flight
Japan on Sunday successfully launched a climate change monitoring satellite on its mainstay H-2A rocket, which made its final flight before it is replaced by a new flagship model designed to be more cost competitive in the global space market.
Pakistan flash floods, heavy rain kill 45 in just days
Heavy rain and flash flooding across Pakistan have killed 45 people in just a few days since the start of the monsoon season, disaster management officials said Sunday.
Earth is trapping much more heat than climate models forecast—and the rate has doubled in 20 years
How do you measure climate change? One way is by recording temperatures in different places over a long period of time. While this works well, natural variation can make it harder to see longer-term trends.
Cold baths, climate shelters as Southern Europe heat wave intensifies
Authorities across Southern Europe urged people to seek shelter Sunday and protect the most vulnerable as punishing temperatures from Spain to Portugal, Italy and France climbed higher in the summer's first major heat wave.
Buried for 23,000 years: These footprints are rewriting American history
Footprints found in the ancient lakebeds of White Sands may prove that humans lived in North America 23,000 years ago — much earlier than previously believed. A new study using radiocarbon-dated mud bolsters earlier findings, making it the third line of evidence pointing to
Scientists just reconstructed half the neanderthal genome—thanks to Indian DNA
India’s complex ancestry—intertwined with Iranian farmers, Steppe herders, and local hunter-gatherers—has now been decoded through genomic data from 2,762 people. The study uncovers surprising levels of Neanderthal and Denisovan DNA, and how ancient migrations and community
The gene that hijacks fear: How PTEN rewires the brain’s anxiety circuit
Deleting a gene called PTEN in certain brain cells disrupts the brain’s fear circuitry and triggers anxiety-like behavior in mice — key traits seen in autism. Researchers mapped how this genetic tweak throws off the brain's delicate balance of excitation and inhibition in the
Brain scan breakthrough reveals why Parkinson’s drugs don’t always work
Researchers are using an advanced brain imaging method called MEG to understand why Parkinson’s drug levodopa doesn’t work equally well for everyone. By mapping patients’ brain signals before and after taking the drug, they discovered that it sometimes activates the wrong brain
This brain scan sees Alzheimer’s coming—but only in some brains
USC researchers have found a promising new brain scan marker that could better detect Alzheimer’s risk — but only for some. The tau-based benchmark works in Hispanic and White populations when paired with another Alzheimer’s protein, amyloid, but falls short for Black
Why brands are embracing fantasy: The psychology behind escapist marketing in anxious times
Why did Aritzia open a café inside its flagship store in Toronto? Why did Burberry pivot from fashion photography to cinematic ads that transport viewers into dreamlike sequences? And why is Simons, Canada's remaining department store, incorporating art and interactive
A strange bright burst in space baffled astronomers for more than a year. Now, they've solved the mystery
Around midday on June 13 last year, my colleagues and I were scanning the skies when we thought we had discovered a strange and exciting new object in space. Using a huge radio telescope, we spotted a blindingly fast flash of radio waves that appeared to be coming from
Scientists reveal a spontaneous reaction that could have started life
Scientists have uncovered a surprising new way that urea—an essential building block for life—could have formed on the early Earth. Instead of requiring high temperatures or complex catalysts, this process occurs naturally on the surface of tiny water droplets like those in sea
New Orleans is sinking—and so are its $15 billion flood defenses
Parts of New Orleans are sinking at alarming rates — including some of the very floodwalls built to protect it. A new satellite-based study finds that some areas are losing nearly two inches of elevation per year, threatening the effectiveness of the city's storm defenses.
