Once fruitful, Libyan village suffers climate crisis

In the Libyan village of Kabaw in the Nafusa Mountains, M'hamed Maakaf waters an ailing fig tree as climate change pushes villagers to forsake lands and livestock.

Once flourishing and known for its figs, olives, and almonds, fields around Kabaw, located some 200 kilometres (124 miles) southwest of Tripoli, are now mostly barren and battered by climate change-induced drought.

'Meaty rice'? South Korean professor aims to change global protein

In a small laboratory in Seoul, a team of South Korean scientists are injecting cultured beef cells into individual grains of rice, in a process they hope could revolutionize how the world eats.

From helping prevent famines to feeding astronauts in space, team leader and professor Hong Jin-kee believes his new so-called "meaty rice" could become an eco-friendly, ethical way for people to get their protein.

Low snow on the Himalayas threatens water security: study

Millions of people dependent on Himalayan snowmelt for water face a "very serious" risk of shortages this year after one of the lowest rates of snowfall, scientists warned Monday.

Snowmelt is the source of about a quarter of the total water flow of 12 major river basins that originate high in the region, the report said.

Quantum computers are like kaleidoscopes − metaphors illustrate science and technology

Quantum computing is like Forrest Gump’s box of chocolates: You never know what you’re gonna get. Quantum phenomena – the behavior of matter and energy at the atomic and subatomic levels – are not definite, one thing or another. They are opaque clouds of possibility or, more precisely, probabilities. When someone observes a quantum system, it loses its quantum-ness and “collapses” into a definite state.

Quantum phenomena are mysterious and often counterintuitive. This makes quantum computing difficult to understand. People naturally reach for the familiar to attempt to explain the unfamiliar, and for quantum computing this usually means using traditional binary computing as a metaphor. But explaining quantum computing this way leads to major conceptual confusion, because at a base level the two are entirely different animals.

Space weather forecasting needs an upgrade to protect future Artemis astronauts

NASA has set its sights on the Moon, aiming to send astronauts back to the lunar surface by 2026 and establish a long-term presence there by the 2030s. But the Moon isn’t exactly a habitable place for people.

Cosmic rays from distant stars and galaxies and solar energetic particles from the Sun bombard the surface, and exposure to these particles can pose a risk to human health.

Foreign-born pandas join China’s efforts to boost wild population

After years of charming millions of people around the world with their furry bodies and clumsy antics, foreign-born giant pandas are adapting to new lives in China.

The fluffy envoys are loaned to overseas zoos as part of Beijing’s “panda diplomacy”, with the offspring returned to China within a few years of their birth to join breeding programmes.

100 years ago, our understanding of the universe exploded

Astronomers, maybe more than anyone, appreciate what an island of perfection our Earth is. Our orbit may put us at a perfect distance from the sun for life to flourish, but it is too small to easily help astronomers determine how big the universe is.

Late Renaissance scholar Nicolaus Copernicus suggested that the Earth orbits the sun in 1543, but it took 300 years to prove it.

Google’s use of AI to power search shows a problematic approach to organizing information

From government documents to news reports, commerce, music and social interactions, much of the world’s information is now online. And Google, founded in 1998 with the mission “to organize the world’s information and make it universally accessible and useful,” is the way we access this torrent of knowledge and culture.

In April 2024, Google’s search engine accounted for 90 per cent of the Canadian search market. For academics, its specialized Google Scholar and Google Books are mainstays of our research lives.

It’s Earth Day 1990, and Meryl Streep walks into a bar. She’s distraught about the state of the environment. “It’s crazy what we’re doing. It’s very, very, very bad,” she says in ABC’s prime-time Earth Day special, letting out heavy sighs and listing jumbled statistics about deforestation and the hole in the ozone layer.

The high-tech art lab hidden underneath Paris

It looks like the lair of a Bond villain: behind armored doors, buried underground below the Louvre in Paris, lies one of the most high-tech art labs in the world.

Across three floors and nearly 6,000 square meters, the Centre for Research and Restoration of Museums of France (C2RMF) includes its own particle accelerator called AGLAE, and is bustling with radiologists, chemists, geologists, metallurgists, archaeologists and engineers.

North Macedonia's beekeepers face climate change challenge

Every day, Magda Miloseska dons a white, protective suit and enters the domain of the honeybees in the backyard of her small weekend house in North Macedonia.

She has been producing honey in this picturesque corner of the country for more than 20 years. But climate change and disease have made what used to be a simple pleasure much harder work, she says.

Gray whales shrinking fast as climate warms

Pacific coast gray whales have shrunk in length an astonishing 13 percent since 2000, adding to evidence that climate change and other human activities are making marine mammals smaller, a study says.

Their diminished size could have big impacts on survival rates and reproductive success -- and trigger ripple effects throughout their entire food webs.

Polar bears could vanish from Canada's Hudson Bay if temperatures rise 2C

An international team of scientists said Thursday that polar bears faced local extinction in Canada's Hudson Bay by mid-century if global warming exceeds limits set under the Paris climate accords.

Climate change has sharply increased the number of days where Arctic sea ice is too thin for polar bears to hunt seals.
