If you were a bird flying thousands of miles over land or sea with other migrating birds, what would you talk about to pass the time? Songbirds may converse with other species during their long migrations, forming social bonds and possibly exchanging information about the flight, according to a new study led by researchers at […]
Like humans, animals experience complex emotions like empathy, love, grief and joy. They can also hold grudges. In a recent study, a team of biologists found that ants can learn from experience and hold grudges when confronted with competitors from another nest with whom they’ve had previous negative experiences. “We often have the idea that […]
Most spiders have eight legs, no ears and use fine leg hairs connected to nerve cells or their webs to hear sounds in their environment. But how do they smell? A new study by an international team of researchers has found that male spiders “smell” with their legs, using olfactory hairs — wall-pore sensilla — […]
Global sea temperatures reached an all-time high in 2024, according to a new study published Friday in the journal Advances in Atmospheric Sciences. The 54 researchers from seven countries deployed thousands of instruments to collect ocean data both at the surface and up to 2,000 meters below the surface — the latter called ocean heat […]
Fueled by the climate crisis, the global average temperature soared above the 1.5 degrees Celsius threshold for the first time in 2024, intensifying extreme weather. Experts from the United Nations World Meteorological Organization (WMO) have confirmed that last year was the planet’s hottest on record, reaching 1.55 degrees Celsius above the pre-industrial average, reported UN […]
Microplastics — the ubiquitous tiny plastic particles that are the result of the breakdown of plastic water bottles, packaging and synthetic clothing fibers — can run through wastewater treatment plants, making their way into the environment. Researchers have engineered bacteria that is commonly found in the treatment plants to break down microplastic pollution before it […]
A quarter of all freshwater animals, including crustaceans, fish and insects, face a high risk of extinction from threats like pollution, farming and dams, a new study has found. Rivers, lakes, wetlands and other bodies of freshwater cover a relatively small amount of Earth’s surface — less than one percent — but are home to […]
In Australia, researchers are considering how genetic engineering could allow mosquitoes to produce venom proteins, like those produced by spiders and sea anemones, in their sperm to transfer the poison to female mosquitoes when mating. In a study led by Macquarie University, researchers first used genetically modified fruit flies to test what has been dubbed […]
In 1979, when President Jimmy Carter famously unveiled 32 solar panels on the White House roof, he remarked, “A generation from now, this solar heater can either be a curiosity, a museum piece, an example of a road not taken or it can be just a small part of one of the greatest and most […]
