Drone footage shows orcas chasing and killing great white shark

Scientists say behaviour, filmed in South Africa, has never been seen in detail before – and never from the airScientists have published findings confirming that orcas hunt great white sharks, after the marine mammal was captured on camera killing one of the world’s largest sea predators.A pod of killer whales is seen chasing sharks during an hour-long pursuit off Mossel Bay, a port town in...

Glass microspheres aren't the answer for saving Arctic sea ice

A proposal to cover Arctic sea ice with layers of tiny hollow glass spheres about the thickness of one human hair would actually accelerate sea-ice loss and warm the climate rather than creating thick ice and lowering the temperature as proponents claim, according to a new study.

Documenting the world's crop diversity and making it available

Genebanks play an important role in the long-term conservation of plant genetic resources for food and agriculture. Out of 1,800 genebank collections worldwide, more than 600 are in Europe. This vast array of crop diversity can be exploited to make our crops more nutritious, productive and resilient to pests, diseases and environmental changes, only if we have information about it.

How does Airbnb contribute to projecting the image of tourist destinations?

"Wander around Trastevere like a Roman"; "This little café in the Latin Quarter in Paris is wonderful"; "Tips to make you feel like a real Berliner." An increasing number of platforms in the sharing economy such as Airbnb are using slogans like these to create and project the image of tourist destinations in the digital world.

Science fiction exhibition in London takes visitors on a journey into space

Voyage to the Edge of Imagination at the Science Museum uses AI and interactive exhibits to create an immersive experienceScience fiction often taps into preoccupations of the day, from the existential threat of nuclear war to the rise of advanced AI. But when it comes to climate change, humanity is on such a clear trajectory that dystopian fiction is no longer required to picture where we might...

New approach improves identification of natural-gas emitters

A new study in New Mexico's San Juan Basin will boost efforts to identify and reduce methane emissions, a key element of the Global Methane Pledge. The research team found that using multiple methods to measure the ratio of ethane to methane in the ambient air around fossil energy development regions can be used to attribute emissions to specific polluters.

A possible explanation for Uranus's odd tilt angle and opposite spin

A small team of researchers with members from Sorbonne Université, the University of Maryland College Park, the University of Pisa and Université Côte d'Azur has developed a theory to explain the odd tilt of Uranus and its opposite spin. The group has published a paper describing their work on the preprint server arXiv and are awaiting results of peer review before it is published in the...

New RNA-based tool can illuminate brain circuits, edit specific cells

Researchers have developed a customizable, RNA-based platform to target cells rather than genes. CellREADR enables scientists to add any protein to a designated cell type. Initial evidence demonstrates the new technology works for brain tissue in rodents and humans and its design relies on an enzyme found in every animal cell, suggesting easy adoption for other creatures and organs. It may provide...
