Coal power is costing India up to 10% of its rice and wheat crops

According to new research led by researchers at Stanford University in the US, coal-fired power plants are quietly depleting India’s rice and wheat output, destroying up to 10% of the yield in several states. The emissions from coal power plants include carbon dioxide, nitrogen oxides, sulphur oxides, fly ash, soot, suspended particulate matter, and other … Read more

How will Trump’s fund cuts hit the US’s technological competitiveness?

America has already lost its global competitive edge in science, and funding cuts proposed in early 2025 may further a precipitous decline. Proposed cuts to the federal agencies that fund scientific research could undercut America’s global competitiveness, with negative impacts on the economy and the ability to attract and train the next generation of researchers. I’m an astronomer, and … Read more

Evolution of intelligent life on earth may not have been so unlikely

A popular model of evolution concludes that it was incredibly unlikely for humanity to evolve on Earth, and that extraterrestrial intelligence is vanishingly rare. But as experts on the entangled history of life and our planet, we propose that the coevolution of life and Earth’s surface environment may have unfolded in a way that makes the evolutionary … Read more

Researchers spot a clue as to why human and mouse genomes overlap

Eighty million years ago humans, rats, and mice shared the same mammalian ancestor. More recently, researchers made the astonishing discovery that even today our genomes contain close to 500 segments that have remained totally unchanged since then. These segments are called ultra-conserved elements (UCEs). Nearly all the UCEs are also highly unchanged in the chicken … Read more

Why don’t century years get leap days unless divisible by 400?

Time measurements and calendars have often been refined over the years. | Photo Credit: Alexey Savchenko/Unsplash A: A tropical year is the time (365.242199 days) the earth takes to revolve around the sun once. By having just 365 days in a calendar year, 0.242199 days are lost each year. To correct this error, Julius Caesar … Read more

The Science Quiz | Unusual materials

Questions: 1. This material is one of the lightest solids known, since more than 99% of its composition by volume is air. Making it involves extracting the liquid component of a particular type of semisolid by supercritical freezing. Name it. 2.

Baboons and human fear: a deep history behind the cruel attacks in South Africa

Encounters between baboons and people are common in parts of South Africa. WhatsApp groups often share stories of baboons raiding a kitchen and stealing all the food. And stories appear in the media about the torture and killing of baboons. Recently the hashtag #JusticeForRaygun has been widely shared on social media. A young male baboon named Raygun was being tracked as … Read more

Art and science illuminate the same subtle proportions in tree branches

Do artists and scientists see the same thing in the shape of trees? As a scientist who studies branching patterns in living things, I’m starting to think so. Piet Mondrian was an early 20th-century abstract artist and art theorist obsessed with simplicity and essence of form. Even people who have never heard of Mondrian will likely recognize his … Read more

Chinese rivals to Musk’s Starlink accelerate race to dominate satellite internet

Space is about to get more crowded for Elon Musk. The billionaire’s Starlink communications network is facing increasingly stiff challenges to its dominance of high-speed satellite internet, including from a Chinese state-backed rival and another service financed by Amazon.com founder Jeff Bezos. Shanghai-based SpaceSail in November signed an agreement to enter Brazil and announced it … Read more

Physicists propose tabletop experiment to test gravity’s quantumness

General relativity and quantum mechanics are two highly successful theories. The former explains gravity and the latter teams up with special relativity to describe the other three forces of nature: electromagnetic, strong nuclear, and weak nuclear forces. However, scientists don’t know how gravity fits into quantum mechanics. In fact, they have been proposing experiments that … Read more
