How many holes does the human body have?
The human body is very complex, with several openings and several exits. But exactly how many holes does a person have? This seems like an easy question to answer. List job information and add them up. However, when you start thinking about questions like “What exactly is a hole?”, it’s not so simple. “Do openings […]
AI is getting better at generating faces, but it can be trained to spot fakes
Facial images generated by artificial intelligence (AI) are so realistic that it is only by chance that even an elite group of “super-recognizers” with extremely powerful facial processing abilities can detect fake faces. People with typical cognitive abilities are worse than chance, most of the time assuming that AI-generated faces are real. This is according […]
6 ‘lost’ cities that archaeologists have yet to discover
Archaeologists are busy unearthing lost civilizations, but they haven’t found everything. There are still prominent ancient cities, such as capitals of great kingdoms and empires, that have not yet been excavated by scholars. We know about these cities because they are described in ancient texts, but their locations can be lost over time. In some […]
Eye denture surgery, ‘blood chimerism’ and pregnancy from oral sex: 12 bad medical cases we covered in 2025
Each week, Live Science features interesting case reports from the medical literature, exploring unusual symptoms, rarely seen diagnoses, and ready-to-use treatments. This Diagnostic Dilemma series describes how doctors work to finally discover the cause of a patient’s illness. In complex cases, this diagnostic process can be very difficult. One reason doctors share case reports is […]
10 things we learned about our ancestors in 2025
Our understanding of how our species evolved has improved dramatically since we began analyzing ancient DNA. This year, researchers made impressive discoveries spanning 3 million years of human evolution, most of which relied on DNA, genome, or proteomic analyses. Here are 10 major discoveries about human ancestors and ancient relatives that scientists will announce in […]
Winter constellations that are easy to find even for beginners
On a clear winter night, the sky looks like a starry blanket, but it’s not a blanket, it’s a map. Constellations are signposts to the stars, simple stick figures that turn randomly scattered points of light into things you can recognize, remember, and navigate. Just learn a few things and the whole winter sky will […]
Flat-headed cat not seen in Thailand for 30 years rediscovered
Researchers have photographed a rare cat in Thailand that has not been seen in the country for about 30 years. And it’s so adorable. The flathead cat (Prionailurus planiceps), named for its flat forehead, is scattered across Brunei, Indonesia and Malaysia, but was feared to be extinct in Thailand. Researchers rediscovered the cat in Thailand’s […]
We now know much more about how our ancestor ‘Lucy’ lived — and died
From a distance, it might have looked like a small child was wending her way through the waving grass along a vast lake. But a closer look would have revealed a strange, in-between creature — a big-eyed imp with a small head and an apelike face who walked upright like a human. She may have […]

This condition is known as a “watering” perineum. The man had a history of various urinary problems, […]
Breakthrough in graphene supercapacitors could improve energy storage capabilities in future EVs and other household devices
Scientists have discovered a new way to manipulate graphene to create a material with record energy and power density. This new form of graphene, when incorporated into energy storage devices called supercapacitors, could be the key to high-capacity, fast-charging energy storage that can deliver power faster than traditional batteries, the researchers said in a statement.
