Researchers and artists have created a striking facial reconstruction of a Stone Age woman who lived roughly 10,500 years ago in what is now Belgium. The detailed depiction of the prehistoric hunter-gatherer, known as the “Margaux woman,” is based on various scientific data, including the remains of her skeleton and ancient DNA, according to a … Read more
Scientists have developed a new kind of “electronic ink” that can be used to print electronic circuits capable of switching between rigid and soft states when heated. The technology could pave the way for next-generation electronic devices that change shape or stiffness depending on how and where they’re used, from medical implants that soften inside … Read more
Despite being known as the Red Planet, Mars shows off its swirling yellows, oranges and browns in a new satellite photo from the European Space Agency (ESA). The Earth-toned surface also reveals an impact crater and four sneaky dust devils making their way across the region. The Rothko-like image was taken by a high-resolution camera … Read more
Ancient DNA from Stone Age burials in Turkey has finally put to rest a decades-long debate about whether the 9,000-year-old proto-city of Çatalhöyük was a matriarchal society. The research finally confirms what experts have long suspected: Women and girls were key figures in this agricultural society. “With Çatalhöyük, we now have the oldest genetically-inferred social … Read more
Artificial intelligence (AI) models can blackmail and threaten humans with endangerment when there is a conflict between the model’s goals and users’ decisions, a new study has found. In a new study published 20 June, researchers from the AI company Anthropic gave its large language model (LLM), Claude, control of an email account with access … Read more
Scientists in Switzerland have created a new “living” material that contains blue-green algae and could one day be used in buildings to fight climate change, they say. Thanks to the blue-green algae, or cyanobacteria, the new material is photosynthetic. This means it can chemically convert carbon dioxide (CO2), sunlight and water into oxygen and sugars, … Read more
After decades of preparation, the Vera C. Rubin Observatory released its first images to the world in a live stream on Monday (June 23). The photos, taken by the world’s largest digital camera, are highly-detailed and show relatively large areas of the sky. In a televised news conference, scientists from the observatory revealed new details … Read more
Nowadays, the dark of night is interspersed with the light of stars. But before the stars were born, did light shine at the beginning of the universe? The short answer is “no.” But the long answer reveals light’s extraordinary journey. At first, the early universe’s light was “trapped,” and it took several hundred thousand years … Read more
The more advanced artificial intelligence (AI) gets, the more it “hallucinates” and provides incorrect and inaccurate information. Research conducted by OpenAI found that its latest and most powerful reasoning models, o3 and o4-mini, hallucinated 33% and 48% of the time, respectively, when tested by OpenAI’s PersonQA benchmark. That’s more than double the rate of the … Read more
Our understanding of plant and tree roots may have been somewhat shallow. New research reveals many plants have a hidden second set of roots that extend far deeper into the soil. According to a new study published June 17 in the journal Nature Communications, this second layer of roots extend over 3 feet (1 meter) … Read more
