We should be open about organoid research to avoid a backlash

Research that involves creating "mini-organs" from human cells, including those from fetuses, may leave people uncomfortable 鈥� so the best approach is to explain the reasoning behind the work and its potential benefits

Melting of Greenland ice could cause European heat extremes this year

When lots of freshwater from Greenland pours into the North Atlantic Ocean, it triggers feedback loops that lead to hotter and drier weather in Europe, according to a study of the past 40 years

Does 23andMe’s decline show genetic-based medicine has been overhyped?

23andMe's DNA test was once named "invention of the year", but now the company is in dire financial straits. Is this a sign that genetically based medicine's promise has been exaggerated?

Photographer Name: Jasper Doest Image Name: Untitled Year: 2024 Image Description: Elephants charge through Livingstone?s narrow streets, their towering figures trumpeting into the night. Altered habitats mean they emerge from the national park at dusk to seek food within Livingstone. A nighttime curfew, urging the community to stay indoors, aims to reduce human-wildlife conflict. Series Name: In the Footsteps of Giants Series Description: The delicate equilibrium between humans and elephants in rural parts of Zambia is being disturbed as both populations vie for limited resources. The expansion of settlements and unsustainable agriculture is encroaching on elephant habitats, jeopardising the well-being of both human livelihoods and the elephant population. The question arises: can humans and elephants coexist? These problems have been escalating in the past decade, and with the expectation of increased droughts due to our warming climate, establishing transfrontier wildlife corridors becomes essential. However, the establishment of these corridors faces challenges posed by settlements, agriculture and infrastructure, which results in daily human-wildlife conflict. As these persistent issues continue it is increasingly evident that the local community plays a vital role in fostering a harmonious coexistence between humans and elephants. Developing economically and socially viable models for coexistence within the local community will be crucial for the long-term survival of both elephants and humans. Copyright: ?

Culture

An animation of the primitive Earth in the process of formation, more than four billion years ago. We view the newborn world from its troubled surface a sea of lava dotted with volcanoes spewing more lava, ash and smoke into the atmosphere. Meteorites fall frequently, illuminating the black, lifeless, surface rocks. And in the sky, the Moon -- much closer to us then than it is now -- endures a similar bombardment.
